Judul: Study of Status and History of Land Use for Smallholding Oil Palm Plantation in Gunung Meriah Sub-district, Aceh Singkil
Abstrak: Kabupaten Aceh Singkil merupakan salah satu sentra perkebunan kelapa sawit di Provinsi Aceh. Luas areal perkebunan kelapa sawit yang terus meningkat setiap tahun menyebabkan terjadinya perubahan penggunaan lahan atau alih fungsi lahan yang diduga berasal dari kawasan hutan. Konversi hutan secara besar-besaran menyebabkan kekhawatiran banyak pihak karena merupakan penyebab deforestasi. Oleh karena itu, perlu dilakukan kajian status dan riwayat penggunaan lahan kebun sawit swadaya di Kabupaten Aceh Singkil. Penelitian dilakukan dengan menganalisis penafsiran citra google earth dan overlay peta kebun sawit swadaya dengan peta kawasan hutan Aceh, peta Rencana Tata Ruang Wilayah Provinsi (RTRWP) Aceh tahun 2011-2031, wawancara, dan studi pustaka. Hasil penelitian menunjukkan bahwa status lahan kebun sawit swadaya menurut peta kawasan hutan Aceh dan peta RTRWP Aceh sebelum menjadi perkebunan adalah Area Penggunaan Lain (APL) dan Arahan Perencanaan Kawasan (APK) Perkebunan. Riwayat penggunaan lahan dan tutupan lahan sebelum menjadi kebun sawit swadaya adalah hutan sekunder dan ladang berpindah., Aceh Singkil Regency is one of the centers of oil palm plantations in Aceh Province. The area of oil palm plantations is increasing annually, causing in land use changes that are thought to be originated from forest areas. Concerns about large scale forest conversion have been blamed by many parties as the cause of deforestation. Therefore, it is necessary to study the origin status and history of land use of smallholdings oil palm plantations in Aceh Singkil District, with an analysis of the interpretation of google earth imagery and an overlay of smallholder oil palm plantation maps with maps of Aceh forest areas, maps of Provincial Spatial Planning (RTRWP) of Aceh, interviews with smallholders’ oil palm owner, and literature studies. The results showed that the status of smallholdings oil palm plantations according to the Aceh forest area map and Provincial Spatial Planning of (RTRWP) Aceh map before being converted into plantations were Other Land Uses (APL) and Area Planning Direction (APK) for Plantation. The history of land use and land cover before becoming smallholdings oil palm plantations is secondary forest and shifting cultivation.

Judul: Economic and Institutional Analyses of Small Holder Palm Oil Plantation in West Kotawaringin District, Central Borneo
Abstrak: Pengembangan sektor perkebunan menjadi prioritas utama di Kabupaten Kotawaringin Barat sejak sektor kehutanan mengalami kemunduran, karena eksploitasi yang berlebihan dan tak terkontrol. Kelapa sawit merupakan 3alah satu komoditi perkebunan yang saat ini menjadi andalan daerah. Walaupun masih didominasi olell perkebunan swasta, tetapi perkebunan rakyat terus mengalami peningkatan. Penelitian ini berupaya mengkaji penomena dall masalah yang dihadapi dalam pengembangan perkebunan kelapa sawit rakyat baik dari aspek ekonomi maupun kelembagaan. Secara lebih spesifik, permasalahan yang dikaji dalam penelitian ini adalah yang terkait dengan masalah kelayakan dan efisiensi usaha, kebijakan pemerintah, sistem kontrak pertauian, serta sistem kelembagaan dan tataniaga dalam perkebunan ke!apa sawit rakyat., In the West Kotawaringin district, estate plantation sector development has substituted for forestry sector. This research makes serious efforts to study observable fact a.."J.d problems faGed in dQv~lopment of small holder pahn oil plantation, including economic and institution aspects. Results of this research indicate: small holder palm oil plantations are more efficient if run in fann size of 1-3 ha, land reform policy is still weak as indicated by lack cognition on the propc,ty right of communal society, small profit margin gained by farmers where the benefit belongs to other market players (middleman and processing factories) in crude palm trading, and not so higt probability of under taking institutional refonn in tlus district.

Judul: Approximation of the Median of Poisson Distribution Using the Relation of Poisson-Gamma Distribution
Abstrak: A major drawback of median is that median cannot usually be defined in closed form, even in the cases where their distribution functions are known. This study gives an approximation of the closed form for the median of the Poisson distribution by using the relation of Poisson-Gamma distribution. The approximation uses elementary techniques based on the monotonicity of certain sequences involving tail probabilities of the Poisson distribution and the Central Limit Theorem. Furthermore, a closed form expression for the mean absolute deviation 􀜧|􀜰􀰒 􀵆 􀜯􀝁􀝀􁈺􀜰􀰒􁈻| is also studied. The median is relevant because of the fact that it minimizes the mean absolute deviation of a Poisson random variable (􀜰􀰒􁈻 by considering median as central tendency.
