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.

The relationship of biological properties of peat with oil palm basal stem rot (BSR) caused by Ganoderma. Indonesia as the largest palm oil producer in the world, has the large percentage of oil palm on peatland. The serious problems of cultivating oil palm on peatland is the presence of BSR disease caused by Ganoderma. There are no effective methods to control the spread of this disease. Biological control is an environmentally friendly alternative method focus, but on peatland, the development of this method is constrained by lack of information about the effect of biological environmental factors. This study aims to determine the effect of the biological propertiess of peat on the intensity of Ganoderma attacks on oil palm. The relationship between the intensity of Ganoderma attacks and biological properties of peat was carried out by correlation test. The correlation analysis showed that the biological properties of peat has not correlated with the Ganoderma attacks, except Summed Dominant Ratio of vegetation which tends to positively correlate to the number of Ganoderma antagonists. These results indicate that peatland vegetation management by maintaining the diversity of vegetation around oil palm can help reduce Ganoderma attacks.

Penyusutan lahan pertanian yang subur merupakan kendala yang dihadapi dalam budidaya pertanian di Indonesia. Salah satu upaya yang telah dilakukan untuk mengatasinya adalah dengan memanfaatkan lahan-lahan marginal seperti lahan gambut yang kurang subur dengan memperbaiki kondisi mikrobiologis lingkungan tanaman dengan memanfaatkan mikroorganisme spesifik lokal terutama dari kelompok jamur yang mampu membantu pertumbuhan tanaman. Jamur asal tanah gambut yang diketahui mampu membantu pertumbuhan tanaman adalah Aspergillus sp. Isolat SNTH003 dan Penicillium sp. isolat SNTH001 asal lahan gambut Kuburaya, Kalimantan Barat. Tujuan penelitian ini adalah untuk menguji bahan-bahan berupa limbah yang dapat digunakan sebagai bahan pembawa bagi jamur PGPF. Penelitian telah dilakukan di Laboratorium Hama dan Penyakit Tumbuhan Fakultas Pertanian Universitas Tanjungpura Pontianak, dari bulan Agustus 2010 sampai Februari 2011, meliputi produksi massal jamur pada Medium Kultur Beras, penyiapan, inokulasi dan evaluasi ketahanan jamur PGPF pada bahan pembawa. Dari empat bahan yang digunakan yaitu dedak, ampas sagu, gambut dan serbuk gergajian kayu, penggunaan bahan dedak mampu menghasilkan pertumbuhan dan produksi spora yang lebih banyak dibandingkan bahan lainnya, yaitu sebesar 133108 cfu/gr, tetapi kurang mampu medukung daya tahan spora dalam bahan selama 12 minggu pengamatan. Sedangkan untuk jamur Penicillium sp. isolat SNTH001, bahan yang paling mampu mendukung pertumbuhan dan menghasilkan spora yaitu sebesar 120108cfu/grserta mampu mempertahankan daya hidup spora selama 12 minggu adalah bahan gambut.

Cucumber plants are a popular fruit vegetable in Indonesia. The development of cucumber cultivation on PMK land has problems including poor macro and micro nutrients, mass pH and slow decomposition. Efforts are being made to overcome this problem by using NPK fertilizer to add macro and micro nutrients to the soil, as well as providing Biosaka to reduce excessive use of chemical fertilizers. Biosaka is an elicitor that functions to increase resistance to disease and pests. This research was conducted in Pontianak City, West Kalimantan. Taking place from May 2024 to June 2024. This research used a Split Plot Design consisting of 2 treatment factors repeated 3 times, each replication consisting of 4 sample plants. The first factor of giving Biosaka (F) consists of 2 levels, namely f1 = not given biosaka, f2 = given biosaka and giving NPK (N) consists of 4 levels, namely n1 = 0 g/polybag, n2 = 5 g/polybag, n3 = 10 g/polybag, n4 = 15 gpolybag. The observation variables observed were plant dry weight, root volume, number of fruit/plant, fruit diameter, fruit length, fruit/fruit weight and fruit/plant weight. The results of the research showed that giving 15 g NPK fertilizer/polybag was the best treatment for the growth of cucumber plants and giving 10 g NPK fertilizer/polybag was the best treatment for cucumber plant results on PMK soil. Biosaka treatment was the best treatment in this research. There was no interaction between Biosaka and NPK fertilizer on all observed variables.

The development of long bean cultivation on peatlands has problems including poor macro and micro nutrients, acidic pH, and high cation exchange capacity (CEC). Efforts were made to overcome this problem by using chicken manure to improve the biological, physical and chemical properties of the soil, as well as adding Trichoderma sp to accelerate the decomposition of chicken manure as organic material. This research was carried out in Punggur Kecil Village, Sungai Kakap District, Kubu Raya Regency, which took place from March 1 2024 to May 13 2024. This research used a Factorial Completely Randomized Design (CRD) consisting of 2 treatment factors replicated as many times as 3 times, each replication consisted of 4 sample plants so there were 144 plants. The first factor in giving Chicken Manure (K) consists of 3 levels, namely k1 = 100 g/polybag, k2 = 200 g/polybag, k3 = 300 g/polybag and Trichoderma sp (T) consists of 4 levels, namely t1 = 0 g/ polybag, t2 = 5 g/polybag, t3 = 15 g/polybag, and t4 = 25 g/polybag. The observation variables observed in this research were plant height, root volume, plant dry weight, number of productive branches, number of plant fruit pods, fruit/plant weight, and pod/plant length. The results of this research show that giving chicken manure at a dose of 200 g/polybag is the best treatment for the growth and yield of long bean plants in peat soil. However, the dose of Trichoderma sp. best was not found in this study. There was an interaction between chicken manure and Trichoderma sp. to pod length per long bean plant

The development of tomato plants on peat soils has problems including low soil pH and low nutrient availability. Efforts to overcome these problems require liming which aims to increase the pH of peat soil. The ameliorant material used is Sea Shell Ash to improve the biological, physical, and chemical properties of the soil, and the addition of SP-36 fertilizer to increase the growth and yield of tomato plants. This study aims to obtain the best dose of sea shell ash and SP-36 fertilizer for the growth and yield of tomato plants on peat soil. The research was conducted at Bengkayang Dormitory, Jalan Sepakat, from June to August. The design used was a complete randomized design (CRD) consisting of 2 factors, namely the Shell Ash factor (A) and SP-36 Fertilizer (P). The seashell ash factor is a1: with 100 g/polybag, a2: with 200 g/polybag, and a3; with 300 g/polybag. The SP-36 fertilizer factor is p1: with 2 g/polybag SP-36 fertilizer, p2: with 4 g/polybag SP-36 fertilizer, and p3: with 5 g/polybag SP-36 fertilizer. The observation variables in this study included: plant height (cm), root volume (cm3), plant dry weight (g), number of fruits per plant (fruit), fruit weight per plant (g), and weight per fruit (g). The results showed that SP-36 fertilizer had no effect on the yield of tomato plants, but cane ash did.
