Abstract

Pulau Untung Jawa Village is one of the districts in the Kepulauan Seribu Regency, DKI Jakarta. The amount of managed waste in the Pulau Untung Jawa Village is only 30%, while the percentage of the unmanaged waste is 70%. The less optimal waste management in the Pulau Untung Jawa Village is due to limited waste processing facilities and the lack of waste recycling activities which are limited to collecting plastic waste with economic value and then selling it to garbage collectors. If not properly managed, garbage can become a serious problem for preserving the surrounding environment. One of the efforts that can be made to optimize waste recycling is by having a Temporary Waste Storage facility based on the Material Recovery Facility (MRF). This research aims to study waste generation's amount and composition and calculate the MRF land area planning. Waste generation in the Untung Jawa Village Island is 14.1 m3/day with a waste density of 180 kg/m3. The composition of the measured waste is organic 54.21%, paper 1.28%, rubber 2.12%, plastic 14.64%, glass 0.91%, cloth 2.41%, metal 0.37%, nappies 2, 71%, Styrofoam 2.96%, wood 10.12%, B3 waste 0.02% and other types of waste 8.24%. The total MFR land requirement in the planning year is 286.3 m2. With the MRF, the amount of waste that can be recycled in the planning year is 64.96% of the total waste generated, or the equivalent of 1.65 tons/day, with a residual waste of 0.89 tons/day.

Abstract

Beberapa parameter air limbah domestik di IPAL Margasari Kota Balikpapan melebihi baku mutu, yaitu parameter amonia, Biological Oxygen Demand (BOD), dan Chemical oxygen Demand (COD). Salah satu opsi pengolahan secara biologi adalah menggunakan teknik fitoremediasi dengan menggunakan tanaman eceng gondok (Eichhornia crassipes). Penambahan aerasi dapat membantu mempercepat proses penyerapan polutan yang ada pada air limbah. Tujuan penelitian ini adalah untuk mengetahui efisiensi penyisihan dan menganalisis pengaruh variasi massa eceng gondok dan penambahan aerasi terhadap penurunan kadar amonia, BOD, dan COD pada Inlet IPAL Margasari. Penelitian ini menggunakan reaktor sistem batch dengan variasi massa tanaman eceng gondok 500 gram, 750 gram dan 1000 gram. Pengamatan dilakukan secara time series pada hari ke 3, 6, dan 9. Hasil penelitian menunjukkan waktu efektif tanaman eceng gondok dalam penyisihan kadar amonia, BOD, dan COD adalah 3 hari. Pada parameter amonia perlakuan tanpa aerasi 500 gram memiliki efisiensi yang paling tinggi yaitu 99,66% dan untuk parameter BOD dan COD pada perlakuan kombinasi antara fitoremediasi dan aerasi dengan massa 1000 gram dan 750 gram memiliki efisiensi yang paling tinggi yaitu 96,42% dan 85,92% dalam menurunkan kadar BOD dan COD pada air limbah domestik. Air limbah di IPAL Margasari bersifat biodegradable dengan nilai rasio BOD/COD 0,39-0,42.

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

This study objected to finding the best-fit probability distribution method using four distributions: Normal Distribution, Gumbel Distribution, Log Normal Distribution, and Log Pearson Type III Distribution. According to the score of the goodness-of-fit test, Log Pearson Type III was selected as the best-fit probability distribution. Design rainfall and rainfall intensity were also calculated for the return period of 2 years, 5 years, 10 years, 15 years, and 25 years. In relation to the rainfall intensity, the IDF curve was created. The IDF curve shows higher intensity in the first 5 hours of rainfall, and then the trend decreases gradually. Moreover, it shows that the higher the return period, the higher the rainfall intensity. The movement of curves is essential for designing drainage, flood intensity, and planting period.

Abstract

Cassava, a widely used raw material in Indonesia's food industry, amounted to 14.9 million tons in 2022. Typically, cassava peel, comprising 2-5% of the plant, is discarded in landfills or left untreated. However, recent research suggests its potential as a source of refuse-derived fuel (RDF), given its high calorific value of 4253 kcal/kg and 12.55% fixed carbon. Another potential RDF source is spent bleaching earth (SBE), a by-product of oil treatment, containing 20-40% oil. This study explores the impact of different compositions of cassava peel, SBE, and various binders on RDF characteristics. Binders like tapioca flour, durian seed, and rejected papaya were tested in ratios ranging from 70:20:10 to 90:0:10. The findings reveal that the 90:0:10 composition with rejected papaya binder yielded RDF with the highest calorific value and volatile matter content. Specifically, RDF from 90% cassava peel exhibited a calorific value of 5320 kcal/kg, fixed carbon of 13.9%, volatile matter of 80%, ash content of 5.7%, and moisture content of 0.3%. These results meet Indonesia's RDF standards, which mandate a calorific value above 3000 kcal/kg and volatile matter between 50-80%.

Abstract

The laundry wastewater contains phosphates that can lead to eutrophication. Treatment of laundry wastewater with phosphate concentration can be done physically or chemically. The adsorption method was selected due to its high efficacy, and economical operation. Activated carbon derived from Empty Palm Oil Fruit Bunch (EPOFB) biomass waste was utilized as the adsorbent, leveraging its lignocellulosic components such as cellulose, hemicellulose, and lignin, that can adsorb pollutants. This study aims to assess the impact of adsorbent dosage and contact time on the adsorption capacity and phosphate removal efficiency. The activated carbon was produced from EPOFB via carbonization and activation processes at 400°C and KOH 6M. The variables including adsorbent dosage and contact time, ranging from 0.2 to 1.0 g/100mL and 20 to 100 minutes, respectively. Results indicate that the adsorbent dosage affects phosphate removal from synthetic laundry wastewater, while contact time does not significantly impact removal efficiency. The highest removal efficiencies of 67.37% and 70.03% were achieved at optimal doses of 8 g/L and 10 g/L, respectively, with contact times of 20 and 80 minutes. The isotherm model and kinetics of phosphate adsorption onto synthetic laundry wastewater using EPOFB adsorbent were identified as Freundlich and pseudo-second order, respectively.

Abstract

Energy consumption in Indonesia is still mostly dependent on fossil fuels like coal, leading to their gradual depletion. Therefore, there is a need for environmentally friendly alternative energy sources from biomass waste, such as Refuse Derived-Fuel (RDF). Biomass waste with a high calorific value, like palm kernel shells and empty palm kernel bunches (EFB), is promising as RDF raw material. The size of the particles affects the characteristics of RDF because it impacts the structure and composition of RDF pellets. The tested composition ratios of palm kernel shells, EFB, and adhesives were (90:0:10), (80:10:10), (70:20:10), (60:30:10), and (50:40:10), with particle sizes of 60, 80, and 100 mesh. The RDF characteristics evaluated included moisture content, ash content, volatile matter, fixed carbon, and calorific value. The best RDF composition was found to be 70% palm kernel shells, 20% empty palm kernel bunches, and 10% adhesive at a particle size of 60 mesh, resulting in a moisture content of 5.2%, ash content of 4.64%, volatile matter of 78.89%, fixed carbon of 9.64%, and a calorific value of 4404.32 cal/g. XRD analysis indicates that RDF contains amorphous carbon, silica, and, with the addition of EFB, contributes to the potassium content. SEM analysis shows that larger particle sizes of the raw material form larger pores in RDF compared to smaller particle sizes.

Abstract

Wisata Hutan Meranti yang berlokasi di kota Balikpapan merupakan salah satu destinasi wisata baru yang masih berfokus mempromosikan hutan lindung khususnya pohon meranti. Luas wilayah Wisata Hutan Meranti adalah 77 hektar menjadi salah satu sumber daya alam yang sangat berpotensi untuk dikembangkan kedepannya. Hutan yang ditanami jenis pohon meranti ini menghasilkan sampah organik berupa daun dan ranting dalam jumlah yang cukup besar. Sampah organik yang ada di Wisata Hutan Meranti belum dimanfaatkan dengan maksimal karena hanya ditumpuk dan dibakar begitu saja. Hal ini dapat menyebabkan polusi udara dan pencemaran lingkungan. Pembuatan kompos dari bahan organik seperti daun dan ranting dapat menjadi salah satu solusi dalam pemanfaatan sampah organik yang ada di Wisata Hutan Meranti. Produk kompos yang dihasilkan juga dapat dimanfaatkan oleh masyarakat sebagai komoditas dengan nilai ekonomi. Untuk mendukung kegiatan pembuatan kompos, dibangun juga satu buah bangunan rumah kompos yang difungsikan sebagai tempat proses pembuatan dan penyimpanan kompos. Pada kegiatan pengabdian masyarakat juga dilakukan pembagian kuisioner untuk melihat dan mengevaluasi pemahaman masyarakat terkait pengolahan limbah organik khususnya pengomposan.

Abstract

Fossil energy is among the most widely utilized energy sources in Indonesian industry, but its continuous use is leading to its depleted. Refuse-derived fuel (RDF) offers an alternative made from organic and inorganic waste. Durian peel is identified as a promising raw material for RDF due to its high calorific value of 6,274 Kcal/kg. Additionally, Lubricant Treatment Sludge (LTS), which is collected from the oil treatment industry, is used to enhance RDF’s calorific value, as it contains residual oil rich in hydrocarbons. To bind the RDF components, tapioca starch, durian seeds, and rejected papaya were selected as adhesives. The mixture ratios of durian skin, LTS, and adhesive were tested at compositions (90:0:10), (85:5:10), (80:10:10), (75:15:10), and (70:20:10). Subsequent RDF characteristics analyses included tests for moisture content, ash content, volatile matter, fixed carbon, and calorific value. Based on these evaluations, the most optimal composition was determined to be 90% durian peel, 0% LTS, and 10% tapioca starch adhesive. This composition exhibited a moisture content of 1.6%, volatile matter of 74.6%, ash content of 8.4%, fixed carbon of 15.2%, and a calorific value of 3,516 Kcal/kg. Tapioca starch emerged as preferred adhesive due to its favorable properties and characteristics.

Abstract

Sentra Industri Kecil Somber (SIKS) produces sludge waste from the Wastewater Treatment Plant (WWTP). Sludge can be utilized as a renewable energy source, for example by processing it into briquettes. This research uses a mixture of cassava peel biomass to increase the calorific value of briquettes and uses tapioca starch adhesive. The purpose of this research is to analyze the characteristics of briquettes produced by WWTP sludge with a mixture of cassava peel and analyze the optimum composition variation of WWTP sludge and cassava peel waste on briquette characteristics with the composition of WWTP sludge, cassava peel, and adhesive of (10:83:7); (15:78:7); (20:73:7); (25:68:7); (30:63:7). The parameters tested are moisture content, ash content, volatile matter, fixed carbon and calorific value based on ASTM, after which data processing is carried out with the help of software, namely graphs with Sigma Plot and Microsoft Excel software to facilitate and minimize errors or human errors. The water content of briquettes A, B, C, D, E was 4.2%, 4.8%, 5.4%, 5.7%, 5.9%. Ash content 12.8%, 13.7%, 14.5%, 15.6%, 16.8%. Volatile matter 12.2%, 14.3%, 15.2%, 15.9%, 16.2%. Fixed Carbon 70.8%, 67.2%, 64.9%, 62.8%, 61.1%. Calorific value 3301.04 cal/gr, 3245.2 cal/gr, 3223.36 cal/gr, 3187.54 cal/gr, 3172.98 cal/gr. The optimum briquette characteristics that meet SNI 6235-2000 are briquette A with a moisture content of 4.2%, volatile matter of 10.2% and those that are close to SNI 6235-2000 are ash content parameters of 12.8%, fixed carbon of 70.8% and calorific value of 3301.04 cal/gr.
