Model Pembinaan Petani Perkebunan Karet Rakyat Berkelanjutan Di Provinsi Riau
(wahyu sari yeni, 2018-01-09) Nurhamlin, Nurhamlin
Karet alam memiliki peranan penting dalam kehidupan manusia. Tanaman karet selain pelestari fungsi lingkungan hidup (penghasil karbon, konservasi tanah dan air, dan habitat satwa) juga memberikan nilai tambah secara sosial ekonomi kepada masyarakat pedesaan sebagai sumber mata pencaharian dan sumber pendapatan. Namun pada dekade terakhir ini harga karet alam di pasar internasional mengalami kemorosotan yang sangat signifikan, yang mengakibatkan petani karet hidup dalam keadaan miskin. Banyak program pembangunan yang dilakukan pemerintah RI untuk meningkatkan kesejahteraan petani karet namun belum memberikan hasil yang optimal. Berdasarkan hasil analisis Multi Dimensional Scaling (MDS) indeks keberlanjutan ekologi (52,95%), keberlanjutan teknologi (62,35%), keberlanjutan ekonomi (60,18%), keberlanjutan sosial (53,62%) dan keberlanjutan kelembagaan (20,73%). Penataan kelembangan petani karet diharapkan mampu meningkatkan pemberdayaan kepada petani karet sehingga memiliki daya saing yang tinggi yang pada akhirnya akan meningkatkan kesejahteraannya secara berkelanjutan di masa yang akan datang.
Partisipasi Masyarakat Dalam Penetapan Hak Ulayat Di Daerah Aliran Sungai Singingi
(wahyu sari yeni, 2018-01-09) Yusri, Ali; Adlin, Adlin; Handoko, Tito
This study aims to find the problem of weak community participation and the commitment of local governments in establishing customary rights along the singingi river basin in the form of regional regulations in accordance with the mandate of the 35th constitutional court ruling in 2015. The study uses a qualitative approach by interviewing informants from the ancestors of customary land, the local government of Kuantan Singingi district and Riau Malay Customary institutions in Singingi and Singingi Hilir sub-districts. The results of the study show that there are inhibiting factors from the community side in participating in policy making regarding the communal land, namely the apathy attitude; Lack of Knowledge and Understanding of the Community; Strong and entrenched Peternalistic culture; There is no reward (follow-up) for community participation; Poor community responsibility; Community Does not know the mechanism of channeling aspirations; Limited public access to information; The lack of support from community elements that should empower the community such as NGOs and mass media. In addition there are also obstacles from the bureaucratic side, namely: a bureaucratic system that has not given space to the public, tend to reject community involvement under the pretext of high cost, lack of understanding of the bureaucrats about the meaning of participation fundamentally
Studi Kelayakan Energi Pada Daerah Aliran Sungai Wilayah Taman Nasional Kerinci Seblat
(wahyu sari yeni, 2019-01-03) Rauf, Rosnita; Nazalul, Chairul; Azman, Azmil
The group in the Kerinci Seblat National Park area is the main watershed, namely the Batanghari watershed, Musi watershed and the western coastal watershed, the watershed is vital to fulfilling the water needs of the lives and lives of millions of people living in the area . The potential of existing water in the forest area can be used to drive the electricity generation system. Existing water potential is one of the primary energy that can be used as renewable energy. Electric energy is already a primary need for modern Indonesian society today. This situation is characterized by the community's dependence on electrical energy in carrying out activities of daily life, both at home, at the office, in hotels and in industrial processes, all of which rely heavily on electrical energy. Indonesia is blessed with primary energy resources thar are very potential to build new and renewable energy-based power plants such us nuclear, geothermal power, hydropower, niomass, wind power, solar power and ocean wave energythat have notbeen optimall utilized. Consideration of energy conservation and the environment require us to immediatelybe able to ultilize renewable energy – which is easily available and more environmentallt friendly than fossil energy. Alternative energy development is absolutely necessary, therefore it is necessary to survey river potential, especially in the Kerinci Sebelat National Park area (TNKS) to meet the electricity needs of the community. With the availability of these water resources, it can be developed into a Micro Power Plant or Mini Hydro. The purpose of this primary energy utilization is to reduce our dependence on fossil fuel energy use whose availability is starting to worry. Several alternative energy sources that are abundant in Indonesia can be utilized without having to substitute the existing conventional energy values. It is hoped that through the use of new and renewable energy can slowly reduce the priority of using fossil fuel-based energy to further replace its role as a counterweight. The use of conventional energy continues to be used, not diverted and even eliminated, but slowly led to changes in the priority scale of its supply needs in remote areas. The time for modern/big cities to change the paradigm to make new and renewabable energy a new ―lifestyle‖, given that for the sake of the environment in its role to reduce CO2 esmissions

(wahyu sari yeni, 2019-01-03) Mulyadi, Aras; Efriyeldi, Efriyeldi; Ilahi, Ilham
The era of regional autonomy has triggered the development of Dumai City towards a better direction. As a coastal area in Riau Province, it is estimated that it will threaten one of the potential coastal ecosystems, Dumai City is a mangrove forest. This study aims to analyze deforestation of mangrove ecosystems in Dumai City, Riau. Analysis of deforestation using ArcGIS and NDVI clasic version 4.5 software for imagery in 2005, 2010 and 2015. The causes of deforestation were carried out through interviews with the community. In 2005 there was 649.64 ha of mangrove area, but 46.79% of deforestation had occurred in the Dumai City mangrove forest so that in 2010 the remaining area was 345.06 ha. The main factors driving the deforestation of mangrove forests in Dumai City stem from the conversion of land into industrial estates, the construction of ports, roads, plantations, agriculture, and settlements. In addition, it is also caused by the use of mangrove wood for household needs, charcoal wood and building materials. The utilization of mangrove wood can be proven from the magnitude of the percentage of logged-over stumps which is more dominant (amounting to 67.32%) compared to natural dead stumps

(wahyu sari yeni, 2019-01-03) Simanjuntak, Juni Tika; Azka, Mukhamad Adib; Dzikiro, Tesla Kadar
Water is the most important thing in our life. Therefore, the lack of water (deficit) will be very harmful to all living creatures and it is almost certain that water deficit areas will experience drought. Water deficit can be caused by El Nino. In 2015, El Nino is listed at an intermediate level moving towards a strong level. Bima region, West Nusa Tenggara is one of the affected areas of El Nino. Therefore, it is interesting to study the availability of soil mosture in the area. The availability of soil mosture can be measured by a water balance analysis. The study was conducted using rainfall data and temperature from meteorology station Sultan Muhammad Salahuddin. Rainfall and temperature data are averaged over the El Nino period in 2015 to make land balance calculations yielding surplus and deficit data. The supporting data in atmospheric dynamics analysis using sea surface temperature data were processed using GRADS, wind data, and Southern Osilation Index data obtained from BOM (Bureau Of Meteorology, Australia). The method used is the method of calculating the water balance of Thorthwaite Mather , while the method of calculating the nature of rain using the method of classification of rain properties with normal criteria (85% - 115%), below normal (<85%) and above normal (> 115%) then presented in graphic. This condition shows that El Nino has a big influence on availability of soil mosture in Bima, West Nusa Tenggara. The most deficit of soil mosture occured in August.

(wahyu sari yeni, 2019-01-03) Soerianto, M. Genta; Prayoto, Prayoto
Various flora and fauna had disappeared in peat swamp forest before they were recorded, identified, and utilized. Hence, we conducted vegetation analysis in Kampar Peninsula, Riau. There were 44 species from 29 families in two-hectare sample plot. The vegetation community was a regenerating logged-over peat swamp forestand. Shannon-Weiner's Diversity Index for the area ranged from2.21 to 2.88. Tree density and basal area in plot two (186 stems/ha and 17 m²/ha) was higher than plot one (127stems/ha and 8 m²/ha). Tree volume and carbon stock in plot two were (252.19 m³/ha and 100.95 ton/ha)—than they plot one (99.04 m³/ha and 59.75 ton/ha). Syzygium acutifolium has the highest Important Value Index (IVI) in all growth stages. The tree families which have high IVI value were Myrtaceae, Dipterocarpaceae, and Sapotaceae. The forest structure was dominated by tree diameter of less than 20 cm (81%). There were three species that are listed in the IUCN Red list which were found in the area, namely Shorea uliginosa, Gonystylus bancanus, and Combretocarpus rotundatus. Based on the forest’s current condition, we suggest that the policy that regulates logged-over peat swamp forest conversion to acacia plantation or oil palm plantation to be reviewed.
Kesesuaian Jadwal Tanam Melalui Penerapan Sistem Informasi Kalender Tanam Di Kabupaten Siak
(wahyu sari yeni, 2019-01-03) Fahri, Anis; Yusuf, Rachmiwati
The agricultural sector has the most serious impact, especially in the food crop sector which is most vulnerable to climate change. Crop failure in a production center can cause shock in other regions, especially in areas that are not agricultural centers. Changes in rainfall patterns, increased extreme climate events, and rising air temperatures and sea water pollution have caused agricultural production, especially the food crop sub-sector to decline significantly. For this reason, the Research and Development Agency has developed adaptive technology with climate change, namely the integrated Planting Calendar (KATAM) information system. The development of integrated planting calendars is a necessity, which is expected to increase agricultural yields and reduce crop losses due to droughts and floods. This planting calendar provides complete information for farmers. The operational guidelines are set at the sub-district level. KATAM (planting calendar) as one of the important tools in adjusting cropping patterns of food crops with climate change. Delivering information about the direction, strategy and policies of the agricultural sector on climate change in the form of a road map to stakeholders and related parties. Referring to the Recapitulation of the Calendar of Rice Planting Potential of Siak Regency, the planting season of MH 2017/2018 (October 2017 - March 2018), it is known that the paddy planting index is 200%. The suitability of the real planting schedule is compared with the recommended planting schedule covering an area of 8,353 hectares (98.69%).

Rokan Hulu and Rokan Hilir Regencies are included in the Rokan and Kubu Watersheds. In the Rokan Hulu district there are several rivers, two of which are fairly large rivers, the Rokan Kanan River and the Rokan Kiri River. Rokan Hilir Regency is also passed by the Rokan Kanan River, which is a place of union with the Rokan Kiri River. Next to these large rivers there are many tributaries that all flow into the big river. At the edge and along the river, including tributaries, is often a flood subscription during the rainy season. The purpose of this study was to identify floodprone areas, in Rokan Hulu and Rokan Hilir Regencies so as to produce maps of flood-prone areas in Rokan Hulu and Rokan Hilir Regencies. To map flood-prone areas in Rokan Hulu and Rokan Hilir Regencies, it can be done with the help of remote sensing data based on Geographic Information Systems (GIS). From the analysis based on overlay maps of soil types, slope classes, land cover and rainfall with the scores and weightings given for each parameter that influence each other to identify the level of flood vulnerability in the study area, in the safe category 14,709.48 ha or 0.9%, Non-hazardous category 921,554.03 ha or 56.33%, the dangerous category is 496,025.36 ha or 30.32% and the category is very vulnerable for flood disaster 203,790.36 ha or 12.46% respectively from the study area

(wahyu sari yeni, 2019-01-03) Wawan, Wawan
In recent years it has been claimed that the use of peat land for oil palm production was declared to be damaged. To clarify these claims, the research has been done with the purpose of evaluating the suitability and degradation of the peat soil which is used for oil palm plantation in area of PT. Subur Mandiri Lestari (PT.SML). This research has been done with survey method. The research location was determined with purposive sampling methods. While the sampling is done with transect method and the sampling point on every transects was determined with free grid method. On this research there is two transect, each transect had set for 5 and 4 sampling point. The determination of land suitability class is done with limiting factor method with matching technique, while the determination of peat land degradation was done with comparative method. The result of analysis shows that the peat land which is used for oil palm plantation in the area of PT. SML have an actual land suitability class of S3-f (marginally suitable with pH and low base saturation as limiting factor) and the potential land suitability of S2 (suitable). The results of the analysis of peat degradation indicate that peat land are used for oil palm plantations in the area of PT. SML if referring to PP No. 71/2014, PP No. 57/2016 and PP no. 150/2000 all damaged (degraded). However, if the degradation analysis refers to BBSDLP (2018), then the peat land is not degraded

The flood disaster has caused many losses to human life. In an effort to reduce the impact caused by natural disasters, it is necessary to have disaster mitigation. Making maps of flood-prone zones is one form of non-structural mitigation. The purpose of this study was to determine the zoning level of flood vulnerability, design a dynamic model of flood vulnerability, and develop a floodprone area policy in Limapuluh Kota Regency, West Sumatra Province. The method used for the manufacture of flood-prone zones using a geographic information system (GIS) using GIS 10.1 software, then to determine dynamic modeling using a systems approach analyzed with powersim 10. Conclusion 1) Land use for gambir plants (Uncaria Gambir) has a large impact against floods. The mining activities of the excavated land also have a significant effect on the increase in flood disasters. 2) The study area consisted of three flood-prone zones, namely high vulnerability, 6.2% of the total area, prone zones while 50.6% zones were around 43.2% low hazard zones
Nilai Ekonomi Mangroves: Sebuah Meta-Analisis
(wahyu sari yeni, 2019-01-03) Hanifah, Abu; Eddiwan, Eddiwan
This article presents a synthesis of literature that evaluates mangrove ecosystems through metaregression analysis. The main contribution of this study is the first meta-analysis that only focuses on mangrove forests, as one type of wetland in Riau province, Indonesia. The number of studies included in the regression analysis was 44 for a total of 145 observations. We include several regressions with the aim of overcoming outliers in the data as well as possible correlations between observations from the same study. We also investigate possible interaction effects between service types and GDP per capita. Our findings show that mangroves show a decrease in scale results, that GDP per capita has a positive effect on mangrove values, using replacement costs and contingency valuation methods produce higher estimates than using other methods. We also found that there were statistically significant interaction effects that affected the data. Finally, the results of this study indicate that using a weighted regression can provide better compatibility than the others. However, in terms of forecast performance, we found that all the models that were estimated to be carried out, in the same way, were unable to conclusively conclude whether one of the performances could exceed the others

(wahyu sari yeni, 2019-01-03) Nugraha, Idham; Astuti, Puji; Manan, Mardianto; Asteriani, Febby; Hisyam, M. Iqbal
Land cover changes were one of the variables that can affect the watershed system. Land cover changes were in the form of anthropogenic activities. The aim of this research was to identify land cover changes in Sail Sub Watershed using remote sensing data. The data that were used are Landsat 5 TM Imagery year of 2000, 2005 and 2015. The data has been digitized using GIS techniques by on screen digitization. The results showed remote sensing data quite accurate to land cover or land use information extraction with 88% accuration. Land cover in Sub DAS Sail has been classified by using local knowledge. The results shown that land cover in Sub DAS Sail can divided into 6 (six) classes such us built up land, bush, swamp area, agriculture, oil palm plantation and water body. From 2000-2015 built up land area and oil palm plantation has increasing pattern, meanwhile bush and swamp area were decreasing over the year. This condition surely can impact the watershed condition like hydrological conditions. This information will be useful for the watershed management, especially in floods case and the general for regional planning.

(wahyu sari yeni, 2019-01-03) Sadad, Abdul
Tourism in Indonesia is one of the supporting economies that has bright prospects, but until now it has not shown a role that is in line with expectations in the development process in Indonesia. Riau Province is one of the regions on the island of Sumatra whose eco-tourism development is still quite slow, when compared to several other sectors. One of the potentials that can be developed from several types of tourism is natural tourism, including the Nature Tourism of the Bukit Thirty National Park in Indragiri Hulu Regency. The purpose of this study was to find out the government's efforts in managing environmentally sound natural tourism in the Bukit Tigapuluh National Park in Indragiri Hulu district. The method used is a qualitative method through interviews, mainly used to describe (descriptive) and explain (explanatory or confirmatory). The results of this study indicate the potential of Bukit Tigapuluh National Park in Riau Province is very large to be developed, which are located at Camp Granit and Rantau Langsat Village Batang Gansal District, Indragiri Hulu Regency towards ecotourism as well as natural tourism and cultural tourism
Kebijakan Pengelolaan Ekosistem Mangrove Berkelanjutan Di Kabupaten Bengkalis Provinsi Riau
(wahyu sari yeni, 2019-01-03) Mashur, Dadang; Sujianto, Sujianto; Afrizal, Afrizal; Zulkarnaini, Zulkarnaini
The condition of mangrove forests in Bengkalis Regency is now very alarming, caused by the first due to natural factors namely abrasion caused by waves from the strait and secondly because human factors openly cleared mangrove forests by shrimp farming entrepreneurs who allegedly violated the rules and AMDAL and the exploitation mangrove wood that is cut down illegally for social and economic needs, such as the existence of a charcoal trading business, a shaky wood business, and a firewood business. Utilization and development activities in the Bengkalis Regency mangrove ecosystem continue to be carried out without regard to the concept of sustainable development, then Bengkalis Regency has the potential to lose all of its mangrove forests. For this reason, a forest management policy is needed that can truly guarantee the sustainability of mangrove forests so that future generations can enjoy the environmental services of this mangrove forest. At present there are six policies in the form of laws related to the management of mangrove ecosystems. Then each law has a derivative in the form of a Government Regulation (PP), the next policy is at the level of a particular ministry to implement or coordinate the implementation of the law. Damage starts from low, moderate to severe. This has caused the decline in biodiversity and environmental services of mangrove ecosystems due to changes in land function so as to increase disaster risk. Management of mangrove forests in Bengkalis Regency is currently directed to rehabilitation because of the large number of damaged areas so that if the activity is successful, it is expected to restore its ecological function to provide environmental services for the surrounding community and for communities outside the area. However, these rehabilitation activities cannot ignore economic and social issues related to the presence of the surrounding community.

(wahyu sari yeni, 2019-01-03) Nurdin, Nurdin; Suprayogi, Imam; Sujatmoko, Bambang; Suwondo, Suwondo; Mustofa, Riyadi; Anggoro, Hafiz Catur
Galugur Kapur IX Sub district watershed is one of the upper watersheds in the Kotopanjang hydropower reservoir which has the potential to trigger a reservoir sedimentation rate increasement due to land clearing for plantations so that it will speed up the filling of dead bin of reservoir significantly which will have an impact on the reduction of the planned service life of the reservoir. The research objective is to analyze the potential for erosion in the Galugur watershed using Geographic Information System (GIS) as an information of a watershed management policy. The research approach method for erosion estimation is the Universal Soil Loss Equation (USLE) method. The USLE method is influenced by four factors: rain erosivity factor (R), soil erodibility factor (K), downhill length and slope factor (LS), and land utilization factor (CP). These erosion estimation factors are then converted into four thematic maps, namely rain erosivity map (R), soil erodibility map (K), downhill slope and length map (LS), land cover and management map (CP). All thematic maps that have been generated are overlaid and will produce an erosion distribution map. The main results of the study proved that erosion that occurred in the Galugur watershed based on GIS was dominated by low category erosion approximately 43% of the total area of 5787,123 ha. Confirmed by the results of research that states that the Galugur watershed erosion product will blend with the water flow from the upstream to the reservoir, so that the sediment in the reservoirs will occur in large scale quantities. The reservoir sedimentations have the potential to be a threat to the reduction in the service life of the Kotopanjang hydropower reservoir which is designed to operate for 100 years.
