RESPON PERTUMBUHAN BIBIT KELAPA SAWIT DI MAIN NURSERY AKIBAT KOMBINASI PUPUK KOTORAN AYAM DAN NPK PADA TANAH PMK
Full text linkSeedlings of oil palm in the main nursery take place from the age of 4 to 12 months of seedlings, in that period the oil palm seedlings already need additional nutrients in the growing media. Utilization of PMK soil as a growing medium is faced with low soil fertility, low levels of organic matter availability, and lack of nutrient content. The limited carrying capacity of PMK soil needs to be overcome by adding organic matter and nutrients to improve soil fertility of PMK as a growing medium for nurseries in the main oil palm nursery. This study aims to determine the effect and dose of the best combination of chicken manure and NPK fertilizer on PMK soil for the growth of oil palm seedlings at the main nursery stage. The study was conducted in Ngabang, West Kalimantan on January 17, 2022 to May 17, 2022. This study used a field experiment method with a completely randomized design (CRD) one factor, namely a combination of chicken manure and NPK fertilizer. The combinations in question are A= Chicken manure 0 % + 100 % NPK, B= Chicken manure 20 % + 80 % NPK, C= Chicken manure 40 % + 60 % NPK, D= Chicken manure 60 % + 40 % NPK, E= Chicken manure 80 % + 20 % NPK, F= Chicken manure 100 % + 0 % NPK. The variables observed in this study were plant dry weight (g), root volume (cm3), plant height (cm), stem diameter (cm), and number of leaves (strands). The growth response of oil palm seedlings in the main nursery on the 100 % NPK treatment was better than the 100 % chicken manure treatment on the variables of plant height, stem diameter and equally good on the variables of plant dry weight, root volume and number of leaves. Treatment of 100 % NPK resulted in the highest average plant dry weight, root volume, plant height, stem diameter and number of leaves compared to other treatments

Full text linkOil palm supply chain gaps in the Ketungau landscape of Sintang district, West Kalimantan province. The development of oil palm plantations in Sintang Regency has been rapid in the last decade. Sintang Regency has declared to implement sustainable oil palm plantations while still considering environmental sustainability aspects. Management of the oil palm trading system to be effective and efficient is the main indicator of sustainable oil palm plantations. Gap analysis in the trading system is an important effort as a basis for making various policies. The Gap Analysis of Oil Palm Supply Chain in the Ketungau Landscape, Sintang Regency, West Kalimantan Province is aimed to identify the gaps that occur between levels of oil palm trading actors in the Ketungau Landscape, Sintang Regency. The analysis is carried out using a comparison method between the current reality and the perspectives expected by the stakeholders. The results of the analysis show that in the palm oil supply chain in the Ketungau Landscape, gaps still occur at every level of the supply chain. The gap between independent oil palm smallholders and the government is the lack of assistance programs and capacity building for smallholders and improving the quality of infrastructure. The gap between the government and companies is that the government's supervision of palm oil business actors is still not maximal. The gap between independent smallholders and companies is that there is still no understanding between the two parties, especially regarding the quality criteria for FFB. The results of this study indicate that independent oil palm farmers in the Ketungau Landscape still require policy intervention from the government and oil palm companies

DAMPAK KONVERSI HUTAN MENJADI LAHAN PERTANIAN TERHHADAP PEMBANGUNAN DESA STUDI KASUS DI HUTAN LINDUNG PINANG LUAR – KABUPATEN KUBU RAYA
Full text linkForest conversion activities into non forestry purposes impacts on decreasing of forestfunction as a main role sustainable development, especially as water regulators and as carbon storage. Therefore, deforestation not only causes a direct loss of forest habitat but also leads to indirect impacts as ecosystem services deteriorate or fail. Forests provide ecosystem services that include the regulation of weather and climate at local, regional and even global levels. Existence of protected forest Pinang Luar ± 3.228 acres take an important part and people living in the area has a high dependency on the forest. Farming activities become a treat to the forest and their indications show that cropland and palm estate already in the forest area. Land cover changes in protected forest Pinang luar at 2003 – 2012 impacts on villages at ring 1 area hierarchy decrease cause by population growth are not followed by the additional of infrastructures in economy, health and education. It is also caused by landconversion that occurred in the protected forest Pinang Luar. In the period 2003 - 2012, the villages directly affected (ring 1) have a level area hierarchy is much worse compared to villages that are not directly affected (Ring 2). And it affected to the development of the villages in the ring 2 which is better than the village at ring 1. These conditions happen because at the village in ring 1 change only on land not on the impact on the level of development that could affect the region hierarchy. This is in contrast with the ring 2 villages where the changes occur not only on land but also on its impact on the development so as to enhance the region hierarchy in ring 2 villages
