The current study was aimed to determine the effect of ameliorant on Pak choi (Brassica rapa chinensis) productivity, CO2 emissions, and factors affecting the rate of CO2 emission. The study was carried out using a non-factorial completely randomized design with seven treatments. The imposed treatment are without ameliorant (control), 10, 20, 30 ton ha-1 chicken manure, 4 ton ha-1 Dolomite + Chicken Manure @ 10 ton ha-1, Dolomite 4 ton ha-1 + Chicken Manure @ 20 ton ha-1 and Dolomite 4 ton ha-1 + Chicken Manure @ 30 ton ha-1. The variables observed are the chemical properties of peat soil, fresh and dry weight of pak choi, CO2 emissions, and factors that affect CO2 emissions. The results of the study revealed that the combination of Dolomite and chicken manure has a significant effect on the studied parameters and the combination of 4 ton ha-1 dolomite + 30 ton ha-1 chicken manure had the highest pH change (average of 6.36), highest productivity, and CO2 emission (344.42 mg cm-2hr-1). Results of the study can be concluded that Dolomite and chicken manure has a significant effect on the various growth parameters of B. rapa chinensis and the properties of the peat soil.
This study aims specifically to produce an analysis of the suitability of forest plantations on former coal mining land. The research was conducted in two stages. The first stage is a general description of the research area and the second stage is the study of the suitability of forest plantations on former coal mining land. Eucalyptus was chosen because it is able to grow both on marginal lands and in swamps and waterlogging areas, able to adapt to soils with poor drainage, fire resistance and tolerance to soils with low to high salinity. This Sengon plant was chosen because it has the advantage of very fast growth, very diverse uses, and can grow on critical land.
The purpose of this study is to analyze policies on the prevention and handling of forest and land fires in Central Kalimantan Province and analyze the factors that influence the prevention and handling of forest and land fires in Central Kalimantan Province. The study used qualitative research methods, with research informants consisting of the Governor, the Head of the Forest Service, the Head of the Environmental Service, Community Leaders, and the people of Central Kalimantan Province. The data collection technique is done by observation, interview, and documentation study. At the same time, the data analysis used is an interactive model analysis consisting of data condensation, data display, and drawing conclusions/verification. The results showed that in accordance with Regional Regulation No. 5 of 2003 and Governor's Regulation No. 24 of 2017, the policy of preventing and handling forest and land fires in Central Kalimantan Province was carried out in two stages, namely the prevention policy and the policy of handling forest and land fires. However, in its implementation, it prioritizes the policy to extinguish forest and land fires because it has more economic, social, educational, and health impacts. Efforts to prevent and handle forest and land fires in Central Kalimantan Province are constrained by inadequate human resources, limited budget, and lack of facilities and infrastructure.
Kegiatan yang dilakukan pada Kawasan Kanal Kalampangan, Blok C eks PLG, lebih diarahkan pada kegiatan restorasi gambut untuk mendukung pengembangan kegiatan ekowisata dengan memanfaatkan berbagai potensi yang ada di kawasan ini. Posisi kawasan yang tidak jauh dari Palangka Raya, menjadikan lokasi ini penting dan mempunyai keunggulan. Kegiatan yang dikembangkan pada dasarnya sebagai wahana pendidikan tentang gambut yang akan meliputi pemahaman sifat dan ciri gambut, pemanfaatan lahan gambut (utamanya untuk kegiatan pertanian) dan dampak lingkungan yang ditimbulkan serta kegiatan restorasi gambut. Semua objek yang rencananya ditampilkan dalam jalur jalan sepanjang 5-6 km tersebut, diinisiasi melalui pendanaan dari BRG dan selanjutnya diharapkan para stakeholder terkait gambut melakukan investasi dengan membangun sarana wisata tersebut. Hakekat dari kegiatan agroekowisata, selain sebagai wahana pendidikan, juga diharapkan masyarakat di kawasan tersebut menjaga kawasan gambut dari kerusakan terutama akibat kebakaran hutan dan lahan yang terjadi setiap musim kemarau. Kegiatan awal yang dilakukan dengan pendanaan dari BRG mencakup 3R yakni rewetting, revegetasi dan revitalisasi ekonomi masyarakat.
