Abstract

Oil 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.

Abstract

Kebakaran lahan adalah masalah lingkungan yang menimbulkan banyak kerugian di bidang kesehatan, ekonomi dan lingkungan. Tujuan penelitian ini adalah membuat peta kerentanan kebakaran di Kabupaten Kubu Raya. Metode yang digunakan sesuai Perka No. 2 BNPB Tahun 2012. Parameter penyusun bahaya kebakaran hutan dan lahan terdiri dari parameter jenis penutupan, iklim, dan jenis tanah. Setiap parameter diidentifikasi untuk mendapatkan kelas Parameter dan dinilai berdasarkan tingkat pengaruh/kepentingan masing-masing kelas menggunakan metode skoring. Hasil penelitian menunjukkan bahwa terdapat 4 kecamatan di Kabupaten Kubu Raya yang memiliki kerentanan kebakaran yang luas yaitu: Kecamatan Batu Ampar, Kubu, Sungai Raya dan Sungai Ambawang. Namun jika kerentanan kebakaran dipersentasekan per luasan masing-masing kecamatan, maka Kecamatan Rasau Jaya yang memiliki porsi yang paling tinggi yaitu 81%, diikuti oleh Kecamatan Sungai Ambawang, Sungai Kakap, dan Kubu.

Abstract

The use of peat land for the development of oil palm plantations is considered to have a negative impact on the environment based on the release of CO2 emissions. Some of the results of the study show that emissions measurements using a closed hood method with a measurement duration of 2-4 minutes that takes place during the day. The aim of this study was to measure CO2 flux at night on oil palm plantation areas of 9 years and 10 years in peatlands and to analyze the relationship of CO2 flux at night in oil palm plantations on peat with Temperature Soil, Groundwater Face, Water Content Gravimetric, Soil pH, and Eh Soil. Location this research was carried out on the oil palm plantation area of PT. Sintang Raya. The location of the research plot is located in the village of Olak-olak Kubu, Kubu District, Kubu Raya Regency, West Kalimantan in July 2018 until October 2018. Measurements were made using vaisala with CO2 sensors namely InfraRed Gas Analyzer (vaisala) and conducted for ≤4 minutes per plot. This measurement is carried out in the afternoon until the morning and is repeated every 4 hours at 18.00, 22.00, 02.00 and 06.00. The measurement of CO2 flux is done once a week starting from August to September. The results showed that nighttime CO2 flux in oil palm plants on peatland was between 0.27 g CO2 m-2 hours-1 to 0.34 g CO2 m-2 hours-1 or equivalent to 26.86 tons CO2 ha-1 year-1 to 29.74 tons CO2 ha-1 year-1. Differences in levels of organic matterand ash content between peatlands in TM 6 and TM 7 did not cause significant differences in CO2 flux values between the two locations. Variation in the time of measurement of real estate at night, but does not affect real changes in flux values. This is related to the level of organic matter, ash content, and also the temperature associated with CO2 flux, including other factors that also determine the amount of nighttime CO2 flux on peatland.Keywords: CO2 Flux, Measurement Time, Plant Age.

Abstract

Effect of Sludge and MKP Fertilizer Doses on Radish Plant Growth and Yield on Peatsoils. The development of the horseraean plant in peat land is faced with the number of obstacles in low, low ph, inlet, high c-organics with varying degrees of maturity and low - base base soils that are causing the growth and development of plants to be stunted, That would make a sludge delivery out of MKP fertilizer. The study is aimed at seeing the effect that doses of sludge given and MKP fertilizers have on the growth and growth of turnip plants in the peat soil. The research was conducted on KEP’S Agroland at Jl. Sui Raya Dalam, Pontianak City from March 12th to April 31th  2021. The study uses field experimental methods with comprehensive design prosecutions consisting of 2 treatment factors. The first factor is the sludge with the levels of treatment and the second factor is MKP fertilizer. Each factor is repeated 3 times, each denteronomy consisting of 4 plant samples, making the total number of plants 108. The first factor is the dose of sludge and the second is the dose of MKP fertilizer which has three levels of treatment each. Every treatment is repeated three times. A sludge dose consists of 0, 200, 320 g/polybag (equivalent to 0, 25, 40 tons /ha), while the MKP dosage consists of 0, 2, 4 g/polybag (equivalent to 0, 150, 250 kg/ha). The observed variabel is that of the number of leaves, the fresh weight of the plant, the fresh weight of the bulbous, the length of the tuber diameter and the plant’s dry weight. The research suggests and that there is no interaction between her and MKP for all variables. The treatment of sludge and MKP involving a dose of sludge 25 tons/hectares is equivalent to 200 g/polybag and MKP 150 kg/hectares is equivalent to 2 g/polybag is an efficient gift.
