ABSTRACT: A microcosmic experiment was conducted to estimate CO2 emission from peat soils. Two treatments, peat humification levels (F = Fibric, H = Hemic, S = Sapric) and water levels (G0 = 10 cm; G1= 0 cm; G2 = -10 cm; G3 = -20 cm), were tested and arranged according to factorial randomized complete block design (RCBD) with 3 replicates. Current study revealed that CO2 emission was significantly affected (p<0.01) by peat humification levels and water levels. The sapric peat emitted significantly higher CO2 (696.69 b ± 43.95 mg CO2 g-1 peat d-1) than hemic (504.62 a ± 105.72 mg CO2 g-1 peat d-1)and fibric (492.56 a ± 90.69 mg CO2 g-1 peat d-1)peats. Decreases in water level shifted anaerobic condition into aerobic condition, causing significant increases in CO2 emission. Regardless of peat humification levels, CO2 emission and water table depth in current study showed a nonlinier relationship. It seems that a threshold water tables for enhanced CO2 emissions was within the range of -10 to -20 cm below peat surface.Keywords : microcosmic, peat, humification, CO2 emission. ABSTRAK (Indonesian): Tujuan percobaan skala mikrokosm ini adalah untuk estimasi emisi CO2 dari tanah gambut. Pengaruh 2 (dua) perlakuan, yaitu tingkat humifikasi gambut (F = Fibrik, H = Hemik, S = Saprik) dan tinggi muka air (G0 = 10 cm; G1= 0 cm; G2 = -10 cm; G3 = -20 cm), disusun menurut Rancangan Acak Lengkap Faktorial (RALF) dengan 3 (tiga) ulangan. Hasil penelitian menunjukkan bahwa perlakuan tingkat humifikasi gambut dan tinggi muka air mempengaruhi emisi CO2 secara nyata (p<0.01). Emisi CO2 dari gambut dengan tingkat humifikasi saprik menghasilkan emisi CO2 secara nyata lebih tinggi (696.69 b ± 43.95 mg CO2 g-1 gambut hr-1) dibandingkan dengan emisi CO2 dari gambut hemik (504.62 a ± 105.72 mg CO2 g-1 gambut hr-1) dan fibrik (492.56 a ± 90.69 mg CO2 g-1 gambut hr-1). Penelitian ini juga menunjukkan bahwa perubahan suasana reduktif menjadi oksifatif akibat penurunan muka air juga diikuti oleh peningkatan emisi CO2 secara nyata pada semua tingkat humifikasi gambut. Besaran emisi CO2 dan muka air tanah menunjukkan pola hubungan nonlinier pada ketiga tingkat kematangan gambut. Hasil penelitian ini juga menunjukkan bahwa tinggi muka air pada ketiga tingkat kematangan gambut yang menjadi pemicu percepatan emisi CO2 adalah berada pada kisaran -10 to -20 cm di bawah permukaan gambut.Kata kunci : mikrokosm, gambut, humifikasi, emisi CO2.

AbstractUtilization of natural resources in the form of coal mines has a positive impact on economic and energy development, in addition to coal mining activities have a negative impact on the environment that result in environmental pollution in soil, water, and air. Pollution begins when clearing land, taking exploitation, transporting, stockpile and when the coal is burned. When land clearing causes damage to forest ecosystems. At the time of exploitation impact on air pollution by coal dust particles, the erosion, siltation of the river, the pollution of heavy metals and the formation of acid mine drainage (AMD). The high acid conditions cause the faster heavy metals such as Hg, Cd, Pb, Cr, Cu, Zn and Ni present in the coal dissolved and carried to the waters. Coal stockpile activity also causes pollution in the air, soil, and water. At the time the coal is burned as an energy source causes the emission of hazardous materials into the air of Hg, As, Se and CO2 gas, NOx, SO2. This condition has an impact on the environment and ultimately on human health. Keywords: coal, pollution, heavy metal, gas emission Abstrak (Indonesian)Pemanfaatan sumber daya alam berupa tambang batubara berdampak positif dalam pembangunan perekonomian dan energi, disamping itu aktivitas penambangan batubara berdampak negatif bagi lingkungan yang berakibat pencemaran lingkungan di tanah, air dan udara. Pencemaran dimulai ketika membuka lahan, pengambilan batubara (exploitasi), pengangkutan, penyimpanan sementara (stockpile) dan saat batubara tersebut dibakar. Ketika pembukaan lahan untuk penambangan batubara, hutan mulai di tebang sehingga menyebabkan kerusakan ekosisitem. Pada saat exploitasi berdampak pada tercemarnya udara oleh partikel debu batubara, terjadinya erosi, pendangkalan sungai, pencemaran logam-logam berat dan terbentuknya air asam tambang (AAT). kondisi asam yang tinggi menyebabkan semakin cepat logam-logam berat seperti Hg, Cd, Pb, Cr, Cu, Zn dan Ni yang ada pada batubara tersebut terlarut dan terbawa ke perairan. Aktivitas penyimpanan sementara (stockpile) batubara juga menyebabkan terjadinya pencemaran di udara, tanah dan air. Pada saat batubara tersebut dibakar sebagai sumber energi menyebabkan emisi bahan berbahaya ke udara berupa Hg, As, Se dan gas CO2, NOx, SO2. Kondisi ini yang berdampak pada lingkungan dan akhirnya pada kesehatan manusia. Katakunci : batubara, polusi, logam berat, emisi gas.

To simplify the description of the damage phenomenon to the earth, the concept of ecological footprint can be used. This concept is not specifically built to calculate the destruction of the earth. This concept calculates how much space (land and water) humans need to produce the resources they need including absorbing the waste they produce. This study calculates Indonesia's ecological footprint by observing variations according to geography and the level of regional government. This research uses the Environmental Care Behavior Survey Year 2013, Village Potential Census Year 2011 and the 2013 National Social Welfare Survey, or SUSENAS. All were surveyed by the Indonesian Central Bureau of Statistics. As a result, Indonesia's ecological footprint is 1.51 gha. At the provincial level, the ecological footprint of Jakarta is the highest compared to other provinces’ of 1.84 gha. While East Nusa Tenggara has the lowest ecological footprint, which is 1.30 gha. Indonesia's ecological footprint follows the general pattern in the world, of higher ecological footprint in urban area compared to other types of regions such as villages, watersheds, beaches, mountains, forests or hilly areas.

To simplify the description of the damage phenomenon to the earth, the concept of ecological footprint can be used. This concept is not specifically built to calculate the destruction of the earth. This concept calculates how much space (on land and water) humans need to produce the resources they need including absorbing the waste they produce. This study calculates the ecological footprint in Palembang and its surroundings according to demographic factors and local government. To investigate the general pattern of ecological footprint and its determinants based on the respondents’ reports, a survey was launched in October 2017. As a result, the average ecological footprint in Palembang Metropolitan and its surroundings is 0.591 global hectares (gha). The ecological footprint in Palembang Metropolitan and its surroundings is formed by 4 things, namely: diet and food choices, shelter/home life, transportation and lifestyle choices. The largest portion is given by diet and food choices (26.8 percent), while the smallest contribution is contributed by transportation (24.1 percent). Taking into account demographic factors, a high ecological footprint is owned by a group of male individuals, aged 30-39 years, highly educated, working, and after hearing and understanding climate change and ecological footprint. Finally, if observed according to the type of government, metropolitan cities have a high ecological footprint than others. Finally, the ecological footprint of Palembang as a metropolitan city is higher than the others.

Fertilisers, especially those containing NPK nutrients, have become a necessity in farming both rice fields and dry land. Most of the application of fertilisers is based on plant commodities and less based on the nature of the diversity of the soil or growing media. This study aimed to determine the balance of NPK nutrients and the nutrient elements that became the limiting factor in the rice and dryland maize cropping systems. The study was conducted at a rice field in Jember District and on dry land in Bogor District with maize plants. The fertiliser used is organic fertiliser. Nutrient balance is obtained by calculating the difference between the total input of nutrients N, P, and K given and the total output of nutrients N, P, and K transported by plants. The results showed that the combination of fertilizing treatment with biochar (50%), fish waste (25%), and chicken manure (25%) up to 10 t/ha on rice field soil at the experimental location in Jember had to limit factors for plant growth: low organic matter content, trace elements essential nutrients N and P are also low. Likewise, the combination of inorganic NPK fertiliser treatment with organic fertiliser up to 600 kg/ha on dry land in Bogor has not been able to improve its fertility status with limiting factors: low organic matter content, low N-total, and low exchangeable K.

Unpredictable conditions of rice cultivation on fragile peatlands in Indonesia due to land-use changes would be an obstacle to agricultural food production and food security. This study aimed to determine the changes in land usage in Bengkulu, from prospective rice fields to oil palm plantations. The study was conducted from June to October 2020 at Air Manjuto irrigation paddy fields in Mukomuko Regency, Bengkulu Province. The analysis used satellite imagery with appropriate resolutions and multitemporal time from the United States Geological Survey's Landsat 5 Thematic Mapper (TM), Landsat 7 Enhanced Thematic Mapper + (ETM+), and Landsat 8 Operational Land Imager (OLI) collected from the years of 2000, 2008, and 2019. (USGS). The landscapes covering the Air Manjuto area were mostly marginal swampy peaty soils with ordo of Inceptisols, Histosols, and Entisols, which favor intensive rice cultivation. Oil palm plantation covers about 80% of the area, and in the last ten years, the cultivation by small-scale farmers increased sharply, about 8,219 ha or 68% from the previous decade, and no bush and bare land. In contrast, rice fields were an extraordinary loss of 6,819 ha or about 74% in the last decade, from 9,187 ha in 2008 to 2,308 ha in 2019. The loss of a huge area for rice cultivation at the Air Manjuto irrigation area threatens production in Bengkulu. The loss should be reversed through supporting infrastructure facilities and incentives, agrochemical subsidies, and agricultural insurances, and no more rice fields should be converted.

Technical Assistance Using Liquid Organic Fertilizer for Improving Small-Scale Rubber Production in Payaraman Barat, Kabupaten Ogan Ilir. Liquid organic fertilizer (POC) is getting more attention from users (researchers, farmers, planters and others) because of the various advantages it has. Its manufacture is not too difficult and can use local raw materials ( agricultural waste, market waste or potential household organic waste). One of the advantages is that it can reduce the cost of fertilization. POC can be used to improve soil fertility and it is hoped that in the end it will be able to increase the productivity of rubber plants. This community service activity aims to provide technical guidance on how to make POC in a simple way and then apply it to rubber plants, accompanied by sanitation of the garden environment by cleaning weeds. There are four waste materials or plant materials used to make POC, namely pineapple peel waste, papaya fruit, banana peel and water hyacinth. The material is fermented in a simple reactor made of a gallon or bucket of used paint that is perforated and fitted with a faucet. The fermentation process is assisted by black soldier flies which will come into the reactor by themselves. After two weeks it will begin to produce fermented liquid. After four weeks the liquid is dried in the sun until it turns dark brown and is ready to use. In this activity, doses of 10, 20, 30 or 40 mL of POC were dissolved into 1 liter. The results of the socialization showed that 15 members of the farmer group did not know about POC and were very interested in using it. Preliminary data (n=30) showed a fairly large variation in sap production (59.7±48.6 grams/tree). Some rubber stems do not release sap, and the highest can reach 142.9 grams/tree with an average of 41 to 83 grams/tree. The collection of results is carried out every week according to latex sales. After 4 weeks of application of POC pineapple peel production can reach 165 to 470 grams/tree.
