Abstract

One of the businesses in West Kalimantan involved in the rubber industry is PT. X. This business converts raw rubber in the form of lumps and solid sheets into rubber sir, also known as semi-finished rubber. Apart from creating the intended products, PT. X also generates waste in the form of B3 waste from running the machinery that processes rubber. The purpose of this study is to assess, identify, and offer recommendations for the B3 waste management system of PT. X. Using a Likert scale, the evaluation is conducted in accordance with Permen LHK No. 6 of 2021 and PP No. 22 of 2021. Recommendations for B3 waste management are made by taking into account the evaluation results that do not comply with applicable regulations, According to study results, the reduction criteria's evaluation scores were in the 55.56% bracket, which is considered to be fairly good,; the criteria for containers and packaging were 95.24% category 'Very Good'; the criteria for storage was 86.67% category 'Very Good'; the criteria for storage buildings was 94% category 'Very Good'; the criteria for waste labels was 100% category 'Very Good'; and the criteria for transportation was 100% category 'Very Good'. Based on the findings of the evaluation, suggestions are given for the management of B3 waste at PT.X, starting with the phases of reduction, storage, and transportation.

Abstract

Sanitasi masyarakat disediakan oleh Sungai Seminis, yang merupakan sub-DAS dari Sambas dan bermuara ke Sungai Sambas Kecil. Perkebunan kelapa sawit, desa-desa, dan penambangan emas ilegal merupakan mayoritas perubahan penggunaan lahan di Sungai Seminis. Kualitas air sungai dipengaruhi oleh kegiatan-kegiatan ini, yang menyebabkan pencemaran sungai. Tujuan dari penelitian ini adalah untuk mengkatalogkan berbagai sumber pencemaran di Sungai Seminis dan menentukan kualitas airnya menurut tingkat kelas II yang ditetapkan dalam Peraturan Pemerintah No. 22 Tahun 2021 tentang Pengelolaan dan Perlindungan Lingkungan Hidup. Pencemar di Sungai Seminis berasal dari perkebunan, industri skala besar, pertambangan emas saat ini dan masa lalu, dan sebagainya, menurut temuan inventarisasi. “Titik 1 (Area Penambangan Emas Ilegal) dan titik 4 (Area Perkebunan) memiliki nilai Biochemical Oxygen Demand (BOD) masing-masing sebesar 4,44 mg/L, 8,75 mg/L, dan 15,03 mg/L yang tidak memenuhi baku mutu sesuai ketentuan mutu air Sungai Seminis golongan II (Peraturan Pemerintah Nomor 22 Tahun 2021). Sedangkan untuk parameter pH, nilainya sebesar 5,95 mg/L hanya terpaut 5 angka di bawah baku mutu”.

Abstract

Semakin meningkatnya jumlah kebutuhan minyak goreng menyebabkan semakin bertambahnya minyak jelantah yang dihasilkan. Minyak jelantah memiliki kandungan pencemar yang tinggi sehingga bisa menyebabkan kerusakan lingkungan. Penelitian tentang pemanfaatan timbulan minyak jelantah ini dilakukan untuk mengetahui jumlah timbulan minyak jelantah dan pemanfaatannya menjadi pembersih lantai yang dihasilkan dari industri kuliner, khususnya penjual makanan di kawasan kuliner Terminal Mempawah.  Pemurnian minyak jelantah menggunakan arang batok kelapa yang sudah diaktivasi dan menggunakan variasi waktu 24 jam, 48 jam, dan 72 jam. Berdasarkan hasil penelitian yang telah dilakukan diketahui karakteristik minyak jelantah di kawasan kuliner, Terminal Mempawah adalah kadar air 0,522%, asam lemak bebas 14,2%, serta bilangan peroksida 14,39 meq O2/kg. Hasil minyak jelantah yang telah dimurnikan dengan menggunakan arang batok kelapa didapatkan hasil yang paling optimal adalah 48 jam dengan karakteristik kadar air 0,224% asam lemak bebas 12,1% serta bilangan peroksida 6,39 meq O2/kg, dengan efektifitas penurunan kadar air 57%, asam lemak bebas 15% dan bilangan peroksida 55%. Cairan pembersih lantai yang telah dibuat dengan minyak jelantah hasil pemurnian memliki nilai ALT <25 koloni/ml dan telah memenuhi standar baku mutu pembersih lantai, sedangkan parameter pH memiliki nilai 12,6 tetapi belum memenuhi SNI nomor 1842 tahun 2019 tentang pembersih lantai.

Abstract

Population growth in Mukok District, Sanggau Regency, and West Kalimantan Province has resulted in the expansion of residential areas that are difficult to access by local government waste disposal facilities. The enormous volume of waste is the result of the community's lack of understanding of the significance of appropriate waste management and disposal. Burning rubbish is a common sanitary practice. The purpose of this research is to investigate the current waste management system in Mukok District, estimate the expected waste volume till 2032, and build an effective waste management system for Mukok District. The collection and measurement of waste samples adhere to the SNI 19-3694-1994 criteria. Inggis, Semuntai, and Kedukul villages generate 2.66 m3/day, 9 m3/day, and 3.05 m3/day of rubbish, respectively. The waste management plan calls for isolating organic and inorganic trash at the source, using individual containers for each residence, and collecting trash on a daily basis with three-wheeled bike.

Abstract

This Community Service Program (PkM) was carried out at SMA Negeri 3 Pontianak with the aim of providing training to students related to the implementation of Internet of Things (IoT) technology in smart home and smart farming systems. This activity was chosen because most of the Indonesian population does not have an understanding and knowledge of the IoT concept, especially the younger generation of school age. The implementation method includes socialization, training and direct simulation of making IoT-based smart home and smart farming prototypes using ESP8266 sensors as microcontrollers. The PkM activities succeeded in increasing the participants knowledge about IoT.  The results of this questionnaire prove the increased understanding of participants from the delivery of material and increased ability to use and develop IoT and increased learning motivation to apply IoT technology in everyday life. This proves the positive impact of the facilitator's involvement on partners, with this training it is hoped that new ideas or ideas will emerge from the younger generation to face the digital era and be able to identify and solve problems around them by utilizing Internet of Things technology.

Abstract

Pasar Ikan Bersih in Singkawang is a fish market located on GM Situt Street, West Singkawang District. The fish market activities produce waste water from the remaining fish washing which is directly dumped into the river. This activity causes a decrease in the quality of river water around the fish market. The study was conducted to determine the water quality, water quality status using the pollutant index method and the pollution load capacity using the Streeter Phelps. The parameters to be studied are temperature, pH, DO, BOD, COD, and TSS. Parameters such as temperature, pH, and DO are analyzed manually.on site, while other parameters were analyzed in the laboratory. The results obtained from the water quality analysis were that there were several parameters that exceeded the quality standards of class II PP No. 22 of 2021, namely DO, BOD, and COD. In addition, the results obtained from the analysis of water quality status showed that the river was classified as lightly polluted with a value range of 2.36 - 3.44. From these calculations, it shows that the river in Singkawang is able to accommodate a pollution load of 2189.18 kg/day.

Abstract

The catfish farming industry is an industry that uses a lot of water for its production process, so the amount of waste produced is quite large. Waste from fish farming activities generally results from the accumulation of leftover feed used for catfish consumption and the excretion results of the fish being kept. Waste produced from fish farming activities contains organic material in the form of particles. The aim of this research is to analyze the quality of waste water produced in catfish cultivation in terms of the water quality parameters in freshwater fish cultivation SNI 7550:2009, and the efficiency produced in processing liquid waste using the anaerobic method with bamboo media. This research uses the Anaerobic Processing method with bamboo media. Water samples are taken using the grab sampling method. The area studied is the residential scale catfish farming industry. The quality of wastewater discharged from catfish farming, most parameters such as dissolved oxygen (DO), Cadmium (Cd), Lead (Pb), ammonia (NH3), and nitrite (NO2-) do not meet the quality standards specified in SNI 7550: 2009. The anaerobic method significantly succeeded in reducing the concentration of ammonia (NH₃) with an efficiency of 83% and nitrite (NO₂⁻) with an efficiency of 89%, showing efficiency in reducing nitrogen compounds that are harmful to aquatic ecosystems
