Abstract

The objective of this research was to study how much yield difference of fresh fruit bunch of oil palm between dry and rainy season, and whether the yield difference much in dry land compare with wetland. The research was conducted in Entisol of PTPN VII Betung, and in Ultisol of PTP Hindoli, both in Sungai Lilin Regency. Yield data used in this study was data of year 2007−2010. Rainfall data during 2007−2010 showed no absolute dry month during dry seasons. The result of the study indicated that yield in dry land higher than in wetland either in dry season or in rainy season. Yield fluctuated between dry and rainy season either in dry land or in wetland. But, yield in rainy season did not consistently higher than in dry season. It was concluded that oil palm yield was influenced not only by soil water supply and rainfall quantity, but also internal and many other external factors.

Abstract

AbstractUtilization of natural resources in the form of coal mines has a positive impact on economic and energy development, in addition to coal mining activities have a negative impact on the environment that result in environmental pollution in soil, water, and air. Pollution begins when clearing land, taking exploitation, transporting, stockpile and when the coal is burned. When land clearing causes damage to forest ecosystems. At the time of exploitation impact on air pollution by coal dust particles, the erosion, siltation of the river, the pollution of heavy metals and the formation of acid mine drainage (AMD). The high acid conditions cause the faster heavy metals such as Hg, Cd, Pb, Cr, Cu, Zn and Ni present in the coal dissolved and carried to the waters. Coal stockpile activity also causes pollution in the air, soil, and water. At the time the coal is burned as an energy source causes the emission of hazardous materials into the air of Hg, As, Se and CO2 gas, NOx, SO2. This condition has an impact on the environment and ultimately on human health. Keywords: coal, pollution, heavy metal, gas emission  Abstrak (Indonesian)Pemanfaatan sumber daya alam berupa tambang  batubara berdampak positif dalam pembangunan perekonomian dan energi, disamping itu aktivitas penambangan batubara berdampak negatif bagi lingkungan yang berakibat pencemaran lingkungan di tanah, air dan udara. Pencemaran dimulai ketika membuka lahan, pengambilan batubara (exploitasi), pengangkutan, penyimpanan sementara (stockpile) dan saat batubara tersebut dibakar. Ketika pembukaan lahan untuk penambangan batubara, hutan mulai di tebang sehingga menyebabkan kerusakan ekosisitem. Pada saat exploitasi berdampak pada tercemarnya udara oleh partikel debu batubara, terjadinya erosi, pendangkalan sungai, pencemaran logam-logam berat dan terbentuknya air asam tambang (AAT). kondisi asam yang tinggi menyebabkan semakin cepat logam-logam berat seperti Hg, Cd, Pb, Cr, Cu, Zn dan Ni yang ada pada batubara tersebut terlarut dan terbawa ke perairan. Aktivitas penyimpanan sementara (stockpile) batubara juga menyebabkan terjadinya  pencemaran di udara, tanah dan air. Pada saat  batubara tersebut dibakar sebagai sumber energi menyebabkan emisi bahan berbahaya ke udara berupa Hg, As, Se dan gas CO2, NOx, SO2. Kondisi ini yang berdampak pada lingkungan dan akhirnya pada kesehatan manusia.  Katakunci : batubara, polusi, logam berat, emisi gas.

Abstract

Rawa lebak merupakan ekosistem yang dinamis, mengalami perubahan dua arah dari sistem akuatik ke sistem terestrial, dipengaruhi oleh faktor-faktor hidrologi, mutu air, vegetasi, fauna, kepemilikan dan pemanfaatan. Penelitian ini dilaksanakan di rawa lebak Kecamatan Pampangan Kabupaten Ogan Komering Ilir Provinsi Sumatera Selatan, bertujuan untuk merumuskan pola pengelolaan rawa berbasis keterpaduan (integrated system) antara ekologi, ekonomi dan sosial budaya. Pengamatan karakteristik hidrologi, ekologi, pola pemanfaatan, sosial dan budaya menunjukkan bahwa tipologi rawa lebak di lokasi penelitian dapat dibagi tiga yaitu rawa banjiran, rawa tadah hujan dan rawa campuran. Dari hasil analisis keterkaitan faktor internal dan eksternal, penilaian untuk rawa tadah hujan adalah 104 sedangkan rawa banjiran dan rawa campuran masingmasing 68 dan 45. Pola pengelolaan yang dapat disarankan untuk rawa tadah hujan diarahkan pada mempertahankan kekhasan ekosistem dengan pemanfaatan bagi sektor perikanan dengan kegiatan tambahannya adalah pertanian dan peternakan. Pada rawa banjiran diarahkan pada kegiatan pertanian dengan kegiatan lainnya adalah perikanan dan pertanian tergantung pada musim dan ketersediaan air, dan pada rawa campuran diarahkan pada peningkatan efisiensi pemanfaatan air dengan menyediakan lebung dan penyerasian pola tanam dengan daur banjir.Lebak swamp is a dynamic ecosystem, seasonally changed from aquatic to terrestrial ecosystem vice versa. Swamp functions were influenced by charateristic of hydrobiology, water quality, vegetation, wild animal, property right and utilization. The research conducted in lebak swamp of Pampangan Subdistrict, Ogan Komering Ilir District, South Sumatra Province to know environmental characteristic as components to builtd management scheme of those swamp dealing with integrated system between ecology, economy and socio cultural. The characteristics of hydrobiology, ecology, utilization, sociocultural show that in research location, the swamp could be divided into three types,i.e., floodplain swamp, rain-fed swamp and mixed swamp. The result shows that relationship between internal and external factor with ecosystem services gave value of 104 for rain-fed swamp, while floodplain and mixed swamp were 68 and 45 respectively. Suggested management scheme for rain-fed swamp with high ecology score as more natural swamp ecosystem is a fishing area with additional utilization as agricultural land and animal husbandry. Floodplain swamp can manage for agricultural land with additional activity fisheries and animal husbandry depending on season and water table. The management for mixed swamp can suggested primarily on water conservation by preparing fish pool and planting pattern due to maintain water table for agriculture use during dry season.

Abstract

One of the concrete efforts made by the Indonesian government is through social forestry policy as a trigger for land conflicts. One area that has implemented a pattern of social forestry is a forest area located in the management area of the Regional Technical Implementation Unit(UPTD) KPHRegion I Meranti located in Musi Banyuasin Regency. Only 3 social forestry scheme permits have been issued. So the aims of this study was to find out and analyze the process of implementing social forestry policy and analyze the factors that influence. The study was conducted in Pangkalan Bulian and Lubuk Bintialo Villages, Batang Hari Leko District, Musi Banyuasin Regency, South Sumatra Province. Used descriptive method combined (mixed methods) from two different approaches namely quantitative or qualitative approaches. Funding and staff resources (human resources) are still lacking. The process of collective action between actors is running well with the existence of a committed PPS Working Group. Technical rules are clear with the existence of SOPs that are derived from the rules of government and local government.Communication goes well between communities (Forest farmer groups and cooperative members) - local government and facilitators, but not so well between government structures (village heads and apparatus and local government.The Social forestry policy in Musi Banyuasin District, South Sumatra has been effectively implemented from the perspective of policy accuracy in resolving forestry problems and environmental accuracy in accepting policies.
