Abstract

Abstrak: Desa Malikian Kecamatan Mempawah Hilir, Kabupaten Mempawah adalah salah satu desa penghasil kelapa di Kalimantan Barat. Selama ini kelapa diolah menjadi kopra, dengan nilai jual yang rendah. Sementara jika kelapa diolah menjadi virgin coconut oil (VCO) harga jual akan meningkat 5-12 kali lebih tinggi dari kopra. Kegiatan pengabdian ini bertujuan untuk meningkatkan pengetahuan dan keterampilan masyarakat dalam membuat VCO untuk diversifikasi produk minyak kelapa, sehingga berpotensi meningkatkan pendapatan. Metode yang digunakan adalah pelatihan dengan tahapan: penyampaian materi, diskusi, dan praktek langsung membuat VCO. Mitra sebagai peserta pelatihan adalah ibu-ibu anggota PKK yang berjumlah 25orang. Hasil evaluasi menunjukkan bahwa kegiatan pelatihan diterima positif oleh mitra. Pengetahuan dan keterampilan masyarakat dalam membuat VCO meningkat 76,5% dari 21,5% sebelum pelatihan menjadi 98% setelah mengikuti pelatihan. Jika masyarakat konsisten melakukan diversifikasi produk minyak kelapa menjadi VCO, maka pendapatan akan meningkat, dan ke depan dapat diperluas produknya menjadi sabun mandi, shampoo dan body lotion berbasis VCO.Abstract: Malikian Village, Mempawah Hilir District, Mempawah Regency is one of the coconut-producing villages in West Kalimantan. So far, coconuts are processed into copra, with a low selling value. Meanwhile, if coconut is processed into virgin coconut oil (VCO), the selling price will increase 5-12 times higher than copra. The objective of this service activity was to increase the knowledge and skills of the community in making VCO for coconut oil product diversification, so that it has the potential to increase their income. The method used is training with stages: delivery of material, discussion, and hands-on practice of making VCO. Partners as training participants were PKK members, totaling 25 people. The evaluation results show that the training activities were received positively by the partner. Community knowledge and skills in making VCO increased by 76.5% from 21.5% before training to 98% after attending training. If the community consistently diversifies coconut oil products into VCO, their income will increase, and in the future, their products can be expanded into body soap, shampoo, and body lotion based on VCO.

Abstract

Mangrove habitats play an essential role in the sequestration and storage of carbon. Mangroves absorb CO2 through photosynthesis to create carbohydrates stored as biomass in the leaves, stems, and roots. The objective of this study was to estimate the amount of mangrove carbon in the region of the 2012 planting year located in the mangrove forest area of Setapuk Besar Village. Biomass estimation employs a survey and non-destructing method by measuring tree stem diameter at breast height (DBH). According to the findings of this study, the mangrove forest area in Setapuk Besar Village can store up to 139.62 tons of carbon per hectare, equivalent to carbon dioxide (CO2) that can be absorbed at 511.98 tons/ha. Carbon stored above and below the soil surface and soil carbon contain respective values of 65.60 tons C/ha, 50.91 tons C/ha, and 23.11 tons C/ha.Keywords: Carbon stocks, forest biomass, mangrove forest, Setapuk Besar SingkawangAbstrakEkosistem mangrove mempunyai peran untuk menyerap dan menyimpan karbon.

Abstract

Currently, tropical peatland forests are under considerable pressure because of increasing deforestation and degradation of forests. In Kalimantan, degradation and deforestation of peatland forests are driven primarily by industrial logging, expansion of agricultural activities through primarily conversion of forests to agricultural land and oil palm plantations. By the establishment of intensive drainage, it can induce wildfires in peatland. Unmanaged drainage ditches will alter water table levels within the site adjacent to the drainage including to surrounding peatland forest. Water table assessments were conducted before and after peatland drainage on 2007/2009 and 2012/2015 in Kubu Raya, West Kalimantan. This paper studies the effect of drainage ditches into the peatland water table. Results show the establishment of drainage ditches on this peatland landscape lowered the water table by more than 3 times from ~11.7 cm (SE = 1.5, n = 5) to ~37.3 cm (SE = 2.1 cm, n = 26). The effect on the water table was in drier months of July-August. Lowering the water table level altered worst the soil micro climate, peat temperature and peat water content. The results indicate the land use changes in peatland with the establishment of drainage affects peatland water table currently. In the area of less than 500 m from the drainage, the water level tends to lower toward the drainage feature. Therefore, recovery of peatland forests should be initiated by managing the landscape hydrology (i.e. water table) to restore the ecosystem and to protect the remaining peat swamp forest.
