Abstract

One of the priority problems in Balikpapan is the limited availability of raw water. This is due to the rapid growth of domestic and non-domestic activities in Balikpapan while the Manggar Reservoir as the main source of  water supply is almost close to maximum capacity. The impact that will occur is a decrease in the environmental carrying capacity of Balikpapan. So it is necessary to predict when the availability of water in Balikpapan will reach a critical point. The method used in this study is to calculate the need and availability of water in Balikpapan, then calculate the ratio of water availability and demand to determine the carrying capacity and the water criticality index. The results of the calculation of the Environmental carrying capacity status in this study indicate that the water resources in Balikpapan from 2019 to 2029 are worth between 1-2 so that they are included in the conditional safe category. The calculation of the Water Critical Index  shows that in 2019 and 2024 is approaching critical (50-70%). Meanwhile, in 2029 the water criticality index of Balikpapan will reach critical status (84%). So it is necessary to conserve water resources in Balikpapan.

Salah satu wilayah rawan banjir yang ada di Kota Balikpapan adalah daerah Kelurahan Batu Ampar. Masalah yang dapat ditimbulkan oleh banjir sangat merugikan masyarakat, oleh karena itu perlu solusi agar banjir yang terjadi khususnya di daerah Kelurahan Batu Ampar dapat teratasi. Salah satu metode untuk mengurangi potensi banjir adalah dengan pembuatan lubang resapan biopori (LRB). LRB dapat digunakan untuk meningkatkan infiltrasi air pada tanah dengan cara pembuatan lubang resapan. Metode yang dilakukan untuk menentukan jumlah kebutuhan LRB pada Kelurahan Batu Ampar yaitu observasional kuantitatif. Terdapat tiga lokasi yang menjadi daerah rawan banjir pada Kelurahan Batu Ampar. Pada ketiga lokasi dilakukan perhitungan laju infiltrasi pada lubang resapan biopori menggunakan alat double ring infiltometer dan didapatkan laju infiltasi lokasi 1 adalah 0,108 m3/jam, laju infiltasi pada lokasi 2 adalah 0,087 m3/jam, dan laju infiltrasi pada lokasi 3 adalah 0,105 m3/jam. Pada ketiga lokasi pengamatan ditentungan juga debit air limpasan menggunakan periode ulang hujan 2 tahunan didapatkan debit limpasan pada lokasi 1 adalah 263 m3/hari, debit limpasan lokasi 2 adalah 933 m3/hari, dan debit limpasan lokasi 3 adalah 46 m3/hari. Berdasarkan luas wilayah, laju infiltasi, dan debit limpasan didapatkan keperluan jumlah lubang resapan biopori pada Kelurahan Batu Ampar pada lokasi 1 adalah 2.442 buah, lokasi 2 adalah 10.635 buah, dan lokasi 3 adalah 47 buah.

Abstrak: Air bersih di Kota Balikpapan masih belum dapat dinikmati oleh seluruh masyarakat terutama daerah Kelurahan Karang Joang, tepatnya berada di Km 21 RT.41. Penerapan prinsip konservasi air pada kehidupan sehari-hari dapat menjadi solusi dari keterbatasan akses air bersih. Salah satu cara konservasi air yaitu menerapkan sistem pemanenan air hujan di daerah krisis air bersih. Oleh karena pada kegiatan pengabdian masyarakat ini bertujuan untuk meningkatkan pengetahuan masyarakat terhadap penerapan sistem pemanenan air hujan berfilter dalam upaya konservasi air di daerah krisis air. Metode yang digunakan yaitu sosialisasi terkait pentingnya koservasi air, manfaat penerapan sistem pemanenan air hujan berfilter dan cara pembuatan sistem pemanen air hujan berfilter. Berdasarkan hasil sosialisasi sekaligus praktik terjadi peningkatan pemahaman masyarakat sebesar 93% terhadap upaya konsrvasi air melalui penerapan alat pemanen hujan dan filter air hujan. Sedangkan hasil monitoring alat pemananen hujan selama satu minggu, alat pemanen belum berjalan dengan optimal karena dipengaruhi beberapa faktor salah satunya terjadi kebocoran pada bagian inlet tandon dan filter air. Selanjutnya perlu ada perbaikan pada sistem pemanenan air hujan.Abstract: Clean water in Balikpapan City cannot be enjoyed by the whole community, especially in Karang Joang Village at Km 21 RT.41. Applying the principle of water conservation in daily life can be a solution for limited access to clean water. One way to conserve water is to implement a rainwater harvesting system in clean water crisis areas. Therefore, this community service activity aims to increase public knowledge of the application of filtered rainwater harvesting systems in water conservation efforts. The method used is socialization regarding the importance of water conservation, the benefits of implementing a filtered rainwater harvesting system and how to make a filtered rainwater harvesting system. Based on the results of socialization as well as practice, there was an increase in community understanding of 93% of water conservation efforts through the application of rainwater harvesting. While the results of monitoring the rain harvester for one week, the harvester has not run optimally. It is influenced by several factors, one of which is a leak at the inlet of the reservoir and water filter. Furthermore, there needs to be improvement in the rainwater harvesting system.

Abstract

Meranti trees can capture and store carbon from the atmosphere, helping in the mitigation of greenhouse gas emissions. The Balikpapan City government has to realize and maximize its potential. This study intends to calculate biomass, carbon stock, and CO2 uptake in the Meranti ecotourism area in Balikpapan City to help the city's emission reduction target. The biomass of meranti plants was determined using an equation. The biomass of each upper meranti plant was determined using the formula ln(AGB) = -1.533 + 2.294 x ln(DBH) + 0.56 x ln(WD). The lower part uses the equation BGB = AGB x 0.2. The analysis of carbon stocks was conducted using formula C = 0.47x (AGB+BGB). Determine the amount of carbon in leaf waste by multiplying the leaf biomass by the percentage of carbon present. The study revealed that the Meranti ecotourism area in Balikpapan City has a biomass of 7,731 g and a carbon stock of 7,092 g. Both values can decrease CO2 emissions in the atmosphere by 10,711 grams of CO2 per hectare. The Meranti ecotourism region has the potential to expedite the Balikpapan City Government's efforts to reach the aim of lowering greenhouse gas emissions.

Abstract

Microplastics (MPs) significantly damage the environment and human health, leading to a growing global concern. MPs have been detected not only in the natural environment but also in the drinking water treatment process. One of the configurations of the drinking water treatment unit is filtration. Only a few research studies have been published on microplastic removal in the water system. This study was conducted to determine the performance of a rapid sand filter (RSF) in removing microplastics in water with a variation in the effective size (ES) of silica sand and microplastic size. In this study, microplastics are artificially made with size variations of < 400 μm and >400 μm. The filtering uses two variations in the adequate size (ES) of silica sand, namely 0.4 mm and 0.7 mm. At the same time, anthracite is only a control variable with ES = 0.69 with a flow speed of 4 m / h and an observation time of 30, 60, 90, and 120 minutes. The results show that the filter media ES 0.4 has the highest efficiency values of 91.30% for the microplastic size MPs <400 µm and 95.80 % for the larger microplastic >400 µm. In addition, the average percentage removal of ES 0.7 mm was 77.24 % for the size of MPs <400 µm and 95.77% for the size of Mps >400 µm. Gaining insight into the mechanisms involved in removing microplastics from drinking water is essential for developing more effective techniques for eliminating them.
