Desain Sistem Pengelolaan Sampah Melalui Pemilahan Sampah Organik Dan Anorganik Berdasarkan Persepsi Ibu - Ibu Rumah Tangga

Saat ini, volume sampah yang tinggi di Jakarta merupakan salah satu masalah penting bagi masyarakat Jakarta Timur. Berdasarkan data yang diperoleh dari Dinas Kebersihan Pemerintah Jakarta Timur, ada sekitar 30% dari volume sampah yang tidak dikirim ke TPA per hari. Masalah ini berkaitan dengan kurangnya pendidikan tentang pentingnya pemisahan sampah oleh sebagian besar warga. Aturan pemerintah tentang pengelolaan sampah masih belum sepenuhnya dilaksanakan. Suatu lembaga konseling terpadu yang mengelola sampah untuk semua komponen di masyarakat diperlukan untuk memberikan hasil yang optimal. Sistem Pengelolaan Sampah harus melibatkan ibu-ibu rumah tangga dan harus menerapkan Pemerintah Peraturan Nomor 81 Tahun 2012 tentang tentang Pengelolaan Sampah Rumah Tangga dan jenis sampah rumah tangga yang lain. Penelitian ini menunjukkan bahwa dengan menggunakan sistem pemisahan pengelolaan sampah terpadu, volume sampah akan dturunkan sebesar 33%. Penurunan ini disebabkan karena daur ulang sampah anorganik. Melalui cara ini, pemerintah Jakarta hanya perlu untuk mengelola sampah organik yang yang terdiri 67% dari semua limbah. Ini adalah suatu cara untuk mengurangi jumlah volume sampah di Jakart

Forest and Land Fires Are Mainly Associated with Deforestation in Riau Province, Indonesia

Indonesia has experienced extensive land-cover change and frequent vegetation and land fires in the past few decades. We combined a new land-cover dataset with satellite data on the timing and location of fires to make the first detailed assessment of the association of fire with specific land-cover transitions in Riau, Sumatra. During 1990 to 2017, secondary peat swamp forest declined in area from 40,000 to 10,000 km2 and plantations (including oil palm) increased from around 10,000 to 40,000 km2 . The dominant land use transitions were secondary peat swamp forest converting directly to plantation, or first to shrub and then to plantation. During 2001–2017, we find that the frequency of fire is greatest in regions that change land-cover, with the greatest frequency in regions that transition from secondary peat swamp forest to shrub or plantation (0.15 km−2 yr−1 ). Areas that did not change land cover exhibit lower fire frequency, with shrub (0.06 km−2 yr−1 ) exhibiting a frequency of fire >60 times the frequency of fire in primary forest. Our analysis demonstrates that in Riau, fire is closely connected to land-cover change, and that the majority of fire is associated with the transition of secondary forest to shrub and plantation. Reducing the frequency of fire in Riau will require enhanced protection of secondary forests and restoration of shrub to natural forest

Emisi Karbon Dioksida (CO2) Rizosfer Dan Non Rizosfer Dari Perkebunan Kelapa Sawit (Elaeis Guineensis) Pada Lahan Gambut Dangkal

. CO2 emission consists of autotrophic and heterotrophic respirations. An autotrophic emission is not considered as negative, and in contrast, a heterotrophic oxidation of peat soils has detrimental impact on the global warming. The aim of this study is to investigate rates of emissions between autotrophic and heterotrophic respirations, generated by oil palm (Elaeis guineensis) plantation on shallow peat. The research site was located in Rasau Jaya Umum, Kubu Raya District, West Kalimantan Province, Indonesia. The ages of palms are 6 to 7 years. A total of twelve closed chambers were placed in both rhizospheres, representing autotrophic and heterotrophic oxidation, and non-rhizospheres, repsenting heterotrophic oxidation only. CO2 emissions were measured once a month, with an infrared gas analyzer (EGM-4), from January to May 2015. The results show rhizospheric emissions are significantly higher than non-rhizospheric emissions, i.e., 0.93 and 0.44 g m-2 hr-1, respectively. Values of CO2 emissions increase as water table level is low, indicating a positive correlation between water table level and CO2 emission from peats

Capillary Water Rise in Peat Soil as Affected by Various Groundwater Levels

Capillary water in peatlands has a very important role in supplying water to the root zone of plants. The current water content in the root zone depends mainly on groundwater levels in some areas with shallow water levels. The study aimed to measure the capillary water dynamics in peat soils at various soil densities and groundwater levels which were observed from the changes in peat color, moisture distribution, water content and hydrophobicity of peat soil. The study was conducted in the greenhouse of Indonesian Swampland Agricultural Research Institute, Banjarbaru, South Kalimantan. The experiment was arranged in a randomized block design with two factors and three replications. The first factor was the bulk density (BD) of peat, namely BD-1 (on actual condition, 0.1 g cm-3) and BD-2 (compressed into 0.2 g cm-3). The second factor was simulated groundwater levels (GWL) consisting of GWL-1 (-100 cm), GWL-2 (-70 cm) and GWL-3 (-40 cm) from soil surfaces. The results showed that the rise of capillary water in peat soil reached a maximum height of 50 cm which was characterized by the increase in water content at the top layer in the range of 105–127% for BD-1 and 141–181% for BD-2. The highest value of water content (308%) was achieved in the treatment of GWL-3 with BD-2 and the lowest (37%) was in the treatment of GWL-1 with BD-1. The rate of capillary water rose progressively corresponded to the increase in BD value because the number of micropores of BD-2 was greater

Analisis Hubungan Kode-kode Spbk (Sistem Peringkat Bahaya Kebakaran) Dan Hotspot Dengan Kebakaran Hutan Dan Lahan Di Kalimantan Tengah

Land and forest fire is one of causes ofland degradation in Central Kalimantan. Remote sensing dataapplications, especially READY-ARL NOAA and CMORPH data, are benefit forthe available climate observation data. The objectives of this research are: (1) to analyzis relationship between hotspots, FDRS and occurences of land and forest fire, and (2) to develop the estimation model of burned area from hotspot and FDRS codes. The result of this research showed that burned area can not be estimated by using number of hotspots. The drought code (DC) wich is one of FDRS codes has correlation with burned area. So, burned area can be estimated using drought code (DC) (R-sq = 58%) by using the following formula: Burned Area (Ha) = -62.9 + 5.14 (DC – 500)

Air quality and health impacts of vegetation and peat fires in Equatorial Asia during 2004–2015

Particulate matter (PM) emissions from vegetation and peat fires in Equatorial Asia cause poor regional air quality. Burning is greatest during drought years, resulting in strong inter-annual variability in emissions. We make the first consistent estimate of the emissions, air quality and public health impacts of Equatorial Asian fires during 2004–2015. The largest dry season (August—October) emissions occurred in 2015, with PM emissions estimated as 9.4 Tg, more than triple the average dry season emission (2.7 Tg). Fires in Sumatra and Kalimantan caused 94% of PM emissions from fires in Equatorial Asia. Peat combustion in Indonesian peatlands contributed 45% of PM emissions, with a greater contribution of 68% in 2015. We used the WRF-chem model to simulate dry season PM for the 6 biggest fire years during this period (2004, 2006, 2009, 2012, 2014, 2015). The model reproduces PM concentrations from a measurement network across Malaysia and Indonesia, suggesting our PM emissions are realistic. We estimate long-term exposure to PM resulted in 44 040 excess deaths in 2015, with more than 15 000 excess deaths annually in 2004, 2006, and 2009. Exposure to PM from dry season fires resulted in an estimated 131 700 excess deaths during 2004–2015. Our work highlights that Indonesian vegetation and peat fires frequently cause adverse impacts to public health across the region
