Kampar District is traversed by two large rivers and several small rivers, including Kampar River which is ± 413.5 km long with an average depth of 7.7 m, and an average width of 143 m. Referring to Central Statistics Agency Kampar Regency (2015), Kampar residents numbered 703,005 people with a growth of 2.57% that exceeded the national population growth in 2010 of 1.49%. The Kampar Kanan River has a much larger flood impact than Kampar Kiri River because the majority of the population lives along the banks of the Kampar Kanan River. Areas that are always targeted need to be mapped in the form of flood vulnerability maps within Kampar regency. To map areas susceptible to flooding in Kampar District can be done using remote sensing data based on Geographic Information System (GIS). Analysis of the overlay map results as an indicator of flooding in 4 flood vulnerability classes in Kampar regency. Overlaid maps consist of Rainfall Map, Slope Map, Land Use Map and Geological Map, which resulted in the widest area in Kampar District in the prone category of 459,977.89 ha or 42.86% of the district area. The second sequence is in the non-vulnerable category 236,082.39 ha or 22.00%. While the order of the 3rd area is in very vulnerable category that is 219.279.54 ha or 20.43%, and the smallest area is in the safe category of 157,835.01 ha or 14.71% of Kampar Regency area.

This study aimed to determine the application of techniques and the efficiency level of rice farming in Riau Province. Descriptive analysis and Data Envelopment Analysis was used to analyze the efficiency level. The main findings of the study indicate that the application of rice farming technique in Riau Province has not been done properly. The using of maintenance and cultivation technique have not fully implemented the Six Precise system, i.e the exact number, place, type, price, quality, and time. Based on the results of the analysis using DEA: Firstly, most rice farming is technically inefficient because of the land using, seed, fertilizer, pesticide and labor which still exceeds the required capacity. Secondly, almost all rice farmers are inefficiently allocative because of the high ratio of input prices and output prices. Third, rice farming is almost entirely economically inefficient. The policies that can be applied by the government is to subsidize production factors, especially seeds, fertilizers and pesticides. It is necessary to apply the policy of giving bigger price incentive to the farmers on every kilogram of rice produced. Besides, the policy of agricultural insurance to rice farmers need to be applied so that farmers remain motivated to continue to conduct rice farming activities.

Bagaimana Imbal Jasa Lingkungan Mendukung Pengelolaan Das Secara Terpadu Dan Meningkatkan Kesejahteraan Masyarakat? Fakta Dan Potensi Das Musi
(wahyu sari yeni, 2018-09-19) Ulya, Nur Arifatul; Waluyo, Efendi Agus; Kunarso, Adi; Syabana, Tubagus Angga Anugrah
The National Medium Term Development Plan (NMTDP) 2015-2019 states that the Musi watershed is one of the priority watersheds to be restored. Given the coverage of the Musi watershed covering 3 provinces (South Sumatra, Bengkulu and Jambi), 14 districts and 4 municipalities, the utilization and management of the Musi watershed require synergy between stakeholders, including local governments. This study aims to explore the potential of payments of environmental services of Musi watershed using case study approach and data analysis generally refers to an institutional development analysis developed by Ostrom (2008). The payments of environmental services by downstream beneficiaries can make conservation activities become more attractive option for stakeholders in upstream Musi watershed, even encouraging them to adopt this mechanism. Payments for environmental services should be clear, more than an additional benefit to stakeholders regarding alternative land use. Although the reward of environmental services is not designed specifically to improve the welfare of the community but in the implementation of this mechanism can play a role in improving the welfare of the community in the upper Musi watershed. Payments for environmental services approach to communities that maintain and manage upstream watersheds can play a role in improving community welfare.

Watershed management is a planned effort to manage natural environmental factors that are disrupted for river flow and resulting in a change or retention of the watershed resources. Therefore watersheds management is very important in order to gain high productivity and sustainability. Watershed management should be designed as an integrated and sustainable management model. Watershed management should consider the social, economic and institutional aspects of society to address the needs and minimize the conflict of interest among stakeholders, as well as damage control in watershed area. This paper aim is to understand the socio-economic and institutional dynamics in integrated and sustainable watershed management. The method used in this paper presented is through a literature study. The results showed that ownership, pattern of agricultural land use and development of Bajawa city contributed to social economic vulnerability of the watershed. Institutions at the village, kabupaten and central levels have less role in integrated and sustainable watershed management because the conservation activities, especially in the upper watershed, are very low. Therefore, the strategic improvement for integrated and sustainable Aesesa Flores watershed management strongly depend on the institutional aspects
Disparitas Institusi Sosial Masyarakat Tani Hulu Dan Hilir Das Musi Dalam Pemanfaatan Sumberdaya Hutan Dan Air
(wahyu sari yeni, 2018-09-19) Martin, Edwin; Waluyo, Efendi Agus; Ulya, Nur Arifatul
Forests and water are common property resources that often experience tragedy of the common. National policies and programs for damage control of watershed tend to be uniform across and within a watershed. In terms of the site situation, the Musi Watershed landscape in South Sumatra was showing different performance between the regions. Downstream areas have almost no primary natural forests, but upstream there are sporadic forests and not far from the agricultural areas of the community. Therefore, the implementation of national policies and programs requires a location-specific approach, based on an understanding of the interaction of local communities and their environment. This paper aims to explain the differences between social institutions of farming communities in the upstream and downstream of Musi watersheds in the use of forests and water. This comparative study attempts to compare the results of [1] research on Semende's cultural capital in Muara Enim district (upstream) with cultural studies of peoples around the peatlands in OKI (downstream) districts. The study used modern ethnographic approach, through in-depth interview method and participant observation in some villages in OKI District. The results show that there are differences in the worldview of upstream and downstream village communities on forests and water. In addition, the downstream community has more livelihood options, is more adaptive and responsive to technological and market changes, and focuses on financial capital. This disparity implies differences in the existence of social institutions in interacting with forest and water resources. We recommend a different approach in upstream and downstream river basin management. Forest and water resources in the downstream area require the introduction of new social institutions, while upstream needs the strengthening of existing social institutions

Kajian Erosi & Sedimentasi Akibat Perubahan Tataguna Lahan Daerah Aliran Sungai (Studi Kasus DAS Betung Sub DAS Pebari-Jelitik Kabupaten Bangka)
(wahyu sari yeni, 2018-09-19) Sabri, Fadillah
Tin mining activity by the local community of Bangka Belitung has caused quite a serious damage. The changes in land use, especially of watershed land, have increased the number of degraded lands in Bangka Belitung Island Province. From 2006 to 2011there had been an increase in the run off-CH ration by 2% especially in Ajang Mabat and Mancung Watersheds, Bangka Regency and West Bangka Regency. The same goes for the potential of land erosion due to the forests changing into mining areas, which increased by more than 25% for the same period and fitted into the category of severe erosion (BP.DAS Batusa-Cerucuk,2013). Pebari-Jelitik Watershed, the object of this study, has an area of ± 3762 Ha and is a part of BetungWatershed of Bangka Regency that has an area of 14.282 Ha. The soil types are:Aluvial, Kambisol, and Podsolik; most of the area is catchment area that has 0%-8% slope.The land cover consists ofhousing, moor/field, mining area, and plantation. The magnitude of erosion in Pebari-Jelitik Watershed obtained using USLE equation is 1.016.052,6ton/year, or an average of 270,083 ton/ha/year, which fits into the category of class IV (severe). Based on the analysis using the Mayer-Peter andMuler (MPM) equation, the amount of sediment that goes into Pebari-JeitikRiver caused by land erosion is 38.384,78 ton/year in the upstream, 55.119,78 ton/year in the middle,and 52.753,60 ton/year in the downstream. The cause of erosion in the Pebari Jelitik Subwatershed is caused more by the percentage of C value (coefficient of Run Off) which is more than 60% and highly influenced by land use. The value of P (soil management factor) = 1, shows that in the subwatershed there is no soil conservation effort. The material of soil erosion goes into Pebari-Jelitik River and causes a highly unnatural sedimentation in Pebari-Jelitik River. Erosion and Sedimentationare real evidences that the number of degraded lands in Bangka Belitung will continue to increase due to the changes in land use.

(wahyu sari yeni, 2018-09-05) Yanti, Bayu Vita Indah
Kebijakan pemanfaatan dan pengelolaan sumber daya ikan untuk perairan darat salah satunya harus memperhatikan dari sisi keberlanjutan. Salah satu hal yang harus diperhatikan dari sisi pengelolaan pada kegiatan penangkapan ikan adalah pengaturan lisensi hak penangkapan ikan. Pengaturan lisensi hak penangkapan ikan ini bukan merupakan hal baru jika melihat pada praktek penangkapan ikan yang dilakukan di beberapa wilayah perairan darat di beberapa kabupaten di wilayah Propinsi Sumatera Selatan. Lelang lebak lebung sungai (L3S) merupakan salah satu model pengelolaan yang sudah dilakukan secara turun-temurun dalam usaha penangkapan ikan, dan telah diformalkan dalam peraturan daerah. Kajian normatif pada kebijakan L3S ini dilakukan untuk melihat apakah ada perbedaan penerapan kebijakan pengelolaan L3S pada saat dilakukan secara turun-temurun oleh masyarakat adat dengan penerapan L3S secara formal oleh Pemerintah Daerah. Penelitian ini merupakan penelitian hukum normatif, dengan lebih banyak mengkaji (mereview) dari bahan primer peraturan daerah. Berdasarkan hasil kajian, kebijakan pemerintah daerah terkait L3S secara tidak langsung merupakan salah satu bentuk pengaturan lisensi hak penangkapan ikan
