DIMENSI PENGETAHUAN LOKAL DALAM PENGELOLAAN DANAU DI DESA TAMBAK KECAMATAN LANGGAM KABUPATEN PELALAWAN PROVINSI RIAU
(2014-01-29) Bathara, Lamun; Rina; Kusai
Penelitian ini dilaksanakan pada bulan November 2010, di Desa Tambak Kecamatan Langgam Kabupaten Pelalawan Provinsi Riau. Penelitian ini bertujuan untuk mengetahui dimensi pengetahuan lokal masyarakat dalam pengelolaan waduk. Metode yang digunakan dalam penelitian ini adalah metode kualitatif dengan menggunakan pendekatan fenomenologis. Teknik pengumpulan data menggunakan teknik snowball sampling. Data kualitatif diinterpretasikan dengan menggunakan beberapa teori, antara lain: teori dimensi sosial dan budaya masyarakat nelayan, teori konflik sosial nelayan dan teori etika lingkungan. Dimensi pengetahuan lokal masyarakat tergambar dalam tindakan dan cara mereka berinteraksi dengan sumberdaya perikanan di lingkungan mereka yaitu menganggap sumberdaya perairan (danau) adalah anugerah Tuhan Yang Maha Kuasa yang harus dijaga secara bersama-sama. Perairan danau di daerah ini tidak secara bebas diakses oleh setiap orang, karena mekanisme pengelolaannya bersifat regulated fisheries, yakni dalam bentuk lelang. Persepsi masyarakat dalam koservasi sumberdaya perikanan berupa larangan menggunaan pukat tarik dan putas dalam penangkapan ikan di perairan sungai atau danau dan larangan melakukan penangkapan pada suatu lokasi tertentu. Penegakan peraturan dan sanksi bersumber dari masyarakat berupa denda, penyitaan alat tangkap dan larangan beroperasi kembali. Pengelolaan sumberdaya perikanan berbasis masyarakat ini tetap dipertahankan dan dapat dijadikan rujukan pemerintah daerah dalam membuat suatu kebijakan.

PENENTUAN LOKASI BALAI BENIH KEPITING BAKAU DI KABUPETAN INDRAGIRI HILIR
(2014-04-04) Rusliadi
Kabupaten Indragiri Hilir memiliki komoditi perikanan unggulan salah satunya adalah kepiting bakau (Scylla serrata). Sampai saat ini kepiting bakau hanya dieksploitasi dari alam, dengan demikian keberadaan kepiting bakau semakin terancam. Realitas ini mininal didukung oleh 4 hal yang mendasar : 1). Perburuan terhadap induk kepiting bakau semakin meningkat dengan pembongkaran sarang, 2). Semakin rusaknya kawasan hutan mangrove sebagai habitatnya, 3). Semakin menurunnya kualitas perairan di kawasan tempat hidupnya dan 4). Persepsi masyarakat menjelaskan bahwa semakin tahun semakin sulit mencari kepiting bakau. Untuk mengantisipasi kemungkinan punahnya kepiting bakau salah satunya dengan melakukan usaha budidaya. Pemerintah Kabupaten Indragiri Hilir berencana akan membangun fasilitas pembenihan kepiting bakau atau balai benih. Dengan adanya balai benih kepiting bakau ini diharapkan dapat memberikan konstribusi dalam penyediaan benih kepiting baik untuk budidaya maupun restoking Untuk keperluan tersebut diidentifikasi sebanyak 6 lokasi yaitu Sungai Buluh, Pulau Cawan, Tanjung Baru, Kuala Patah Parang, Teritip dan Teluk Nibung. Dari enam (6) lokasi yang diidentifikasi berdasarkan parameter aksessibilitas, topografi, status lahan, kulaitas air, infrastruktur, kodisi tanah, keamanan, tata ruang dan persepsi masyarakat; ternyata lokasi yang paling sesuai untuk lokasi Balai Benih Kepiting di Kabupaten Indragiri Hilir terletak di Desa Tanjung Baru Kecamaatan Tanah Merah. Kelebihan lokasi ini dengan lokasi lain terletak pada parameter aksessibilitas, topografi dan ketersediaan linstrik PLN

(2014-11-09) Rifardi; Edwar, Rufli; Syahminan; Suwarni; Renti, Butar Butar; Nunung, Fidiatur
The main purpose of this study is to reveal the sedimentary enviroments based on sediment characteristics and relative sedimentation rates. The obtained data are all based on analysis results of core samples taken from the Dumai Coastal Waters located off the north coast of Dumai City Indonesia. Bottom sediment samples were collected at 7 stations in the waters using gravity corer in March 2011. The samples were used for mechanical grain size analysis, ignition loss method, and bulk chemical analysis. In addition, the topmost one centimeter of core samples, which approximately 10 cc of wet sediments, was utilized for benthic foraminiferal study, namely, the study of of L/Tl values to infer the relative sedimentation rates. The Dumai Coastal Waters, Riau Province Indonesia is subdivided into three areas based on the general trend of sediment characteristics and relative sedimentation rates as following: 1) the central part of the waters is characterized by coarse-grained sediments, high relative sedimentation rates and dominantly terrigeneous sediments which under influence of rather strong tidal currents, 2) the eastern and western parts of the waters are characterized by relatively coarse-grained sediments, rather high relative sedimentation rates and relatively high biogeneous sediments which are influenced by longshore currents, and 3) the area off the coast (central part) is characterized by fine-grained sediments, the highest relative sedimentation rates. The area correspond to the boundary between the waters masses derived from Rupat Strait and of from Dumai Waters and is under influence of weak tidal current The distribution of crude oil content in sediments indicate that study area under influence of tidal and longshore currents. Judging from the distribution pattern of crude oil content in sediments, sediments polluted by crude oil were transported northwestward and northeastward by longshore currents and spread toward north by tidal currents, of the Dumai Coastal Waters. Key words : sedimentary enviroments, relative sedimentation rates, Dumai Coastal Waters
Komposisi Butiran Pasir Sedimen Permukaan Selat Bengkalis Propinsi Riau
(2014-11-09) Devy, Yolanda Putri; Rifardi
Penelitian ini dilaksanakan pada Bulan Mei-Juni 2012 di Perairan Selat Bengkalis, bertujuan untuk mengetahui material penyusun sedimen secara horizontal di Perairan Selat Bengkalis. Sampel diambil menggunakan Eckman Grab dari 7 titik stasiun kemudian dianalisis untuk menentukan komposisi dan kandungan bahan organik pada sedimen. Hasil penelitian menunjukkan bahwa komposisi sedimen di Perairan Selat Bengkalis tersusun atas lithogenous (batuan, mika, dan kuarsa) dan biogenous (serasah, foraminifera, dan molusca). Komposisi lithogenous khususnya batuan mendominasi di perairan dan keberadaannya merata pada setiap stasiun. Persentase tertinggi terdapat pada lokasi yang dekat dengan daratan dan merupakan salah satu daerah yang mendapatkan pengaruh arus pasang pertama kali sehingga diduga material yang terbawa arus pasang dari Selat Malaka dan arus surut dari Sungai Pakning tertumpuk di sekitar stasiun ini. Selain itu, jenis batuan juga dapat berasal dari hasil erosi dan kegiatan antropogenik di pinggir sekitar perairan. Persentase lithogenous yang terendah terdapat pada daerah yang dekat dengan kawasan mangrove dimana pada stasiun ini tinggi akan komposisi biogenous khususnya serasah karena banyak mendapat suplai bahan organik sertas arus yang lemah mengakibatkan serasah mengendap dengan baik di daerah ini. Kandungan bahan organik sedimen pada stasiun yang dekat dengan kawasan mangrove tertinggi diantara stasiun lainnya karena mendapatkan suplai bahan organik dari kawasan mangrove di sekitar perairan dan arus yang lemah di pinggir perairan menyebabkan bahan organik dapat mengendap dengan baik. Sedangkan stasiun yang mengandung bahan organik terendah berada pada stasiun yang dekat Selat Malaka, ini diduga material yang terbawa arus pasang tidak banyak mengandung bahan organik . Sementara pada stasiun yang dekat dengan Sungai Siak dan Sungai Pakning mengandung bahan organik yang cukup tinggi, hal ini diduga bahwa aliran sungai membawa banyak kandungan bahan organik.

Paddy farming isa key agenda in achieving food security in Malaysia. One of the govemmenrs policies for achieving this goal is through the establishment of the Northern Terengganu Integrated Development Project (IADA KETARA). This study is intended to clarify the effects of IADA KETARA on sustainable paddy farming based on economic, social and environmental aspects. For the purpose of this study, a total of 425 rice farmers were selected as respondents for their perceptions related to the purpose of the study. Determinants of agricultural sustainability were analyzed according to the methods of structural equation modeling (SEM) using the AMOS program. The results showed that the capacity of economic factors have a positive effect (0.011) on the sustainability of rice farming in IADA KETARA while loading factors forsocial and environmental elements also have a negative effect (-0.028 and -0.067).
Archaeology, Culture and History: Concept and Their Contribution in Malaysia
(2015-01-26) Ramli, Zuliskandar
Archeology, history and culture are seen as capable of contributing to national development The three things are linked because the three have a strong bond. In the opinion ofthe author, archaeology, history and culture are in harmony of each other. This is because archeology is part of history and cultural data. including the paleo-environment data (ecofact), which are the primary data in archaeological research. However, this view would conflict with those who adhere to the idea that 'archeology is anthropology or it is nothing. It is the faith of those who subscribe to the "New Archaeology" born in America. The movement began in the late 1950's when American researchers began to move the entire discipline away from the study of artifacts to the study of people behavior. Work of Gordon Willey and Philip Philips in 'Method and Theory in American Archaeology' stated that "American archaeology is anthropology or it is nothing (Whillwy and Phillips 1958: 2). The idea implied that the goals of archaeology were, in fact, the goals of anthropology, which were to answer questions about humans and human society. This was a critique of the former period in archaeology, the culture-historical phase in which archaeologists thought that any information which artifac1s contained is about past people and their way of live once the items are included in the archaeological record. All they felt that could be done was to catalogue, describe and create timelines based on artifacts (Trigger, 1989).

A Real Efforts to Avoid Smoke Claim to Indonesia From the Neighborhood Countries
(2015-01-26) Erdi
Its difficult to argue that the Provmce of West Kalimantan (WK) IS one of the areas that ex1st 1n produc1ng smoke in the event of drought. Combustion is not only done on the fariT] but also 1n residential areas. EnVIronmental clearrup act1vit1es done by the people in the dry seaso ~ is always followed by combustion activities; ranging from household waste burn to grass o r bush burn Thus simultanously, make smoke become a problem not only for the people of West Ka limantan, but also for people 10 neighboring countries. But then, the plantation and forestry sector IS considered as the main culprit of the onset of the smoke and be prolonged paradox Not only WKwho became 1ndustnal smoke in the Southeast Asian region. There are still as many as 13 prov inces were equally strong existence with WKr in producing smoke There are NAD, North Sumatra, We& Sumatra, R1au, Riau Islands, Bangka Belitung Jamb1 South Sumatra, Bengkulu, Lampung, South Kalimantal'\ East Kalimantan and Central Kalimantan. Existence smog was not only due to the absence of local regulations on the prohibition of burning, but also not touching the inte rests of farmers in developing palm oil that owned by the people. When the government issued prohibit burn policy, the industrial estates will obey that regulation, but not for the people. When the local regulation is not accommodating the interests of farmer~ the burning activity is become a smart choice to reduce the production costs and this phenomenon Will be occurs along t1me and never be ending. In the lo calleve~ 1t tu rns out the re are people who do not apply the f1res 1n t he1rplantat1on actiVIties. There IS a custom concept successfully applied on an ongoing basis into the plantation business by a local group 1n West Kalimantan. Apparent ly, it could be put as the good practices of local communities, can be developed to in1t 1ate Indonesia Without smog in the next drought.

(2015-01-27) Windarti; Efizon, Dani; Yani, Alit Hindri; Vicaya, Dwi Sumba
Anabas testudineus is a type fish that commonly inhabit blackwater area such as swamp, stream and canals in Riau. Eventhough this fish can be found easily, information on its biological aspect is rare. To understand the reproductive biology of this fish, a study has been conducted. The A. testudineus was sampled in irrigation canals in the palm tree plantation area in the Bencah Kelubi Village, Kampar Regency, Riau, from January to March 2013. There were 153 fishes ( 68 males and 85 females) captured. The size offish is various, female ranged from 61 -145 mm TL and 11 -126 gr BW, and that of the male was 49- 131 mm n. and 4-79 gr BW. In January, almost all of fish were in the 111 to 2"d maturity stages and there was no mature fish. In February and March, however, there were mature males and females captured. It is predicted that mature male released pheromone that attract females and causing sex ratio between male and female was around 1 : 2.4 in the last 2 months. The male can be distinguished by longer dorsal fin, slimmer and darker body color. Study on histological structure of gonads shown that the ovary of mature female is dominated by mature eggs, indicated that this fish is a total spawner. In the testes tissue, surprisingly, there is trace of egg remains, indicated in special condition this fish might be able to reverse their sex
