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

Identification of Coconut Plantation Area Changes In Sungai Kakap Sub-District Kubu Raya Regency, Land cover turnover and land use cannot be averted. Growth of the city and change in needs of facilities have caused the agricultural and plantation lands to undergo change in their functions. This reasearch aims to identify the change of coconut plantation land area in Sungai Kakap sub-district, Kubu Raya regency. The methods used in this research were surveys and landsat imagery interpretation of 2002 and 2017. The result shows that there were an increasement of coconut plantation area amounted to 6452,19 ha or about 403 ha per year from 2002 to 2017. The increasement of plantation area is due to the improvement of coconuts' selling price, thus encouraging farmers to manage and to expand the plantation area of coconut.

Abstract

Seedlings 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.
