Abstract

ABSTRACTThe use of disposable diapers contributes significantly to environmental issues. One approach to address this issue is to compost. The Takakura method offers a potential solution, although feces in diapers raises concerns about pathogen contamination. This study aimed to evaluate the safety and quality of compost produced from organic waste and disposable diapers using the Takakura method, focusing on fecal coli levels. Organic waste is a mixture of vegetable and fish waste in different proportions. The two treatments tested were 75% organic waste (vegetable/fish) + 25% diapers and 25% organic waste + 75% diapers, observed on days 10 and 20. On day 20, the 75% fish waste + 25% diaper mixture produced the lowest fecal colony level (33 MPN/g), meeting the Indonesian National Standard (SNI) No. 19-7030-2004. The decrease in fecal coli levels was due to microbial interactions, including lactic acid bacteria and Bacillus from fish waste, which have antimicrobial properties. This study shows that composting disposable diapers with the Takakura method and organic waste can produce compost that meets the standard, especially with 75% organic waste composition. However, due to potential pathogen risks, it is more suitable for non-food crops. Keywords: composting, disposable diapers, MPN fecal coli, organic waste, Takakura

Abstract

ABSTRAK  Buruknya kualitas udara menjadi salah satu masalah yang serius untuk kota-kota besar, khususnya Jakarta. Salah satu indikator dalam polusi udara adalah Particulate Matter (PM). Penelitian ini mengkaji pengaruh populasi penduduk, kasus kebakaran, luas ruang terbuka hijau (RTH), dan kadar karbonmonoksida (CO) terhadap kadar PM 2.5 di Jakarta menggunakan metode linear mixed model (LMM). Hasil penelitian menunjukkan bahwa luas RTH memiliki pengaruh signifikan terhadap penurunan kadar PM 2.5 dengan koefisien negatif, artinya semakin luas RTH, semakin rendah tingkat polusi udara. Kadar CO juga berpengaruh signifikan terhadap PM 2.5 secara mandiri. Populasi penduduk, meskipun tidak signifikan secara langsung, menunjukkan pengaruh signifikan ketika diinteraksikan dengan variabel lain terhadap PM 2.5. Di sisi lain, kasus kebakaran tidak berpengaruh signifikan terhadap polusi udara, bahkan interaksinya dengan variabel lain juga tidak menunjukkan pengaruh signifikan. Penelitian ini dapat menjadi acuan bagi pemerintah DKI Jakarta dalam menyusun regulasi dan kebijakan untuk mengendalikan polusi udara, terutama dengan memperhatikan pentingnya memperluas RTH dan mengendalikan kadar CO sebagai upaya mengurangi PM 2.5, serta mencegah dampak buruk kualitas udara terhadap kesehatan masyarakat seperti penyakit pernapasan. Kata kunci: kebakaran, kualitas udara, LMM, pernapasan, polusi ABSTRACT Poor air quality is a serious problem for big cities, especially Jakarta. This study examines the effect of population, fire cases, green open space (GOS) area, and carbon monoxide (CO) levels on PM 2.5 levels in Jakarta using the linear mixed model (LMM) method. The results showed that the area of green space has a significant effect on reducing PM 2.5 levels with a negative coefficient, meaning that the wider the green space, the lower the level of air pollution. CO levels also have a significant effect on PM 2.5 independently. Population, although not significant directly, shows a significant effect when interacted with other variables on PM 2.5. On the other hand, fire cases do not have a significant effect on air pollution, and even their interaction with other variables also does not show a significant effect. This research can serve as a reference for the DKI Jakarta government in developing regulations and policies to control air pollution, especially by paying attention to the importance of expanding green spaces and controlling CO levels as an effort to reduce PM 2.5, as well as preventing adverse effects of air quality on public health such as respiratory diseases. Keywords:  air quality, breathing, fire, LMM, pollution

Abstract

ABSTRAK Biaya energi total PT. Air Minum Bandarmasih Kota Banjarmasin melebihi rata-rata biaya energi nasional pada tahun 2022. Biaya energi yang tinggi disebabkan oleh kondisi topografi di Kota Banjarmasin yang relatif rendah dengan parameter kemiringan tanah hanya sekitar 0,13%. Kondisi tersebut menyebabkan pemanfaatan energi potensial (gravitasi) menjadi kurang optimal dalam proses distribusi air. Salah satu upaya dalam menurunkan biaya energi adalah dengan mengoptimalkan operasional pompa menjadi efisien. Tujuan penelitian ini adalah mengetahui efisiensi penggunaan energi dengan metode perbandingan variasi operasional pompa. Metode penelitian yang digunakan meliputi pengukuran parameter kelistrikan, debit dan tekanan pada pompa distribusi zona BTBS; analisis efisiensi pompa; dan analisis potensi penghematan yang dapat dilakukan. Fokus penelitian dilakukan pada jam operasional pompa pada periode minimum pemakaian air (pukul 23.00 – 05.00). Hasil penelitian menunjukkan biaya listrik dengan operasional menggunakan 2 pompa lebih hemat (sebesar Rp 18.493.621,41 per bulan) dibandingkan operasional menggunakan 1 pompa. Operasional menggunakan 2 pompa memberikan efisiensi pompa rata-rata sebesar 55%, dibandingkan dengan operasional 1 pompa (18,93%). Bahkan potensi penghematan masih bisa dilakukan dengan meningkatkan frekuensi putaran pompa pada suatu batasan tertentu atau dengan menambah 1 unit pompa kapasitas 500 m3/jam. Kata kunci: biaya energi, efisiensi pompa, operasional pompa  ABSTRACT The total energy cost of PT Air Minum Bandarmasih Banjarmasin City exceeds the average national energy cost in 2022. High energy costs are caused by the relatively low topographic conditions in Banjarmasin City with a land slope parameter of only about 0.13%. This condition causes the utilisation of potential energy (gravity) to be less than optimal in the water distribution process. One approach to reducing energy costs is by optimizing the operational efficiency of the pumps. This study aims to assess the energy efficiency by comparing variations in pump operations. The research methodology includes the measurement of electrical parameters, flow rate, and pressure in the BTBS zone distribution pumps; pump efficiency analysis; and potential savings analysis. The study focuses on the operational hours of the pumps during periods of minimal water usage (from 23:00 to 05:00). The results indicate that using two pumps is more cost-effective (saving Rp 18,493,621.41 per month) compared to operating with one pump. The two-pump operation yields an average pump efficiency of 55%, compared to 18.93% for the one-pump operation. Furthermore, there is still potential for savings by increasing the pump rotation frequency within certain limits or by adding an additional pump with a capacity of 500 m3/hour. Keywords:  energy cost, pump operation, pump efficiency

Abstract

ABSTRACT Particulate Matter (PM2.5) is a hazardous air pollutant commonly found in urban areas, where emissions from transportation, industry, and fuel combustion significantly contribute to its concentration, posing serious risks to human health, air quality, and ecosystems. With rapid urbanization (1,073,451 people), transportation activities, and industrial growth, Bandar Lampung faces high PM2.5 concentrations from January to December 2023, up to 10.6 times the WHO threshold limit. This study analyzes the influence of daily meteorological conditions, such as wind speed, humidity, and temperature inversion, on the accumulation of PM2.5 pollutants in Bandar Lampung in 2023, focusing on August as the period with the highest pollution index (ISPU 155). This study utilizes the HYSPLIT application, which analyzes the sources and transport of PM2.5 pollutants based on wind direction. The HYSPLIT model results indicated that pollutants originate from the southeast at an altitude of 500 m and exhibit a more complex pattern at higher altitudes. Low wind speed (2.6 m/s) and low humidity (69%) during the month influenced the accumulation of PM2.5, reaching 53.6 µg/m³, exceeding the national threshold by 10.6 times. This study provided spatial information to support PM2.5 pollution mitigation efforts in Bandar Lampung by using the HYSPLIT model.  Keywords: Bandar Lampung, HYSPLIT, meteorology, PM2.5, wind speed

Abstract

ABSTRAK Ekosistem hutan mangrove di Indonesia memiliki fungsi ekonomis dan ekologis. Salah satu dari potensi ekonomis mangrove R. apiculata merupakan bahan alami yang berfungsi sebagai bioaktif yang digunakan dalam pengobatan bagi manusia maupun hewan. Masyarakat pesisir juga menggunakan daun mangrove sebagai bahan pembuatan produk minuman berkhasiat. Selanjutnya potensi ekologis yaitu menjadi penahan ombak laut dan sebagai habitat biota. Namun, kandungan senyawa daun mangrove yang dikumpulkan dari sekitaran Pantai Lhok Bubon dapat mempengaruhi kelangsungan hidup ikan dan memiliki pengaruh langsung dengan perubahan parameter kualitas perairan. Dampak perendaman daun mangrove ini beresiko mengganggu aktivitas fisiologis ikan kemudian jika perairan mengalami perubahan faktor fisika dan kimia perairan dapat menghasilkan toksik bagi berbagai biota. Tujuan penelitian ini adalah untuk mengetahui nilai LC50-96 jam selama perendaman daun R. apiculata yang berdampak toksik terhadap biota uji. Biota uji yang digunakan adalah ikan molly (Poecilia sp.) yang biasanya digunakan untuk indikator perubahan lingkungan. Penelitian ini dilakukan dengan penentuan konsentrasi antara lain 10, 20, 30, 40, 50% kemudian dianalisis melalui metode analisis probit. Hasil penelitian memiliki nilai LC50-96 jam yang diperoleh dari hasil komposit seluruh perlakuan konsentrasi dari perendaman daun R. apiculata sebesar 559.16 ppm yang artinya termasuk kategori toksik rendah. Meskipun demikian, persentase tingkat toksisitas menunjukkan sebesar 6% sehingga dapat menyebabkan kematian ikan. Kata kunci: LC50-96 jam, toksisitas, mortalitas ikan ABSTRACT  Mangrove forest ecosystems in Indonesia have economic and ecological functions. One of the economic potentials of R. apiculata mangrove is a natural ingredient that functions as a bioactive used in medicine for humans and animals. Coastal communities also use mangrove leaves as ingredients for making nutritious beverage products. Furthermore, the ecological potential is as a barrier to sea waves and as a habitat for biota. However, the content of compounds in mangrove leaves collected from Lhok Bubon coast that can affect the survival of fish directly influences changes in water quality parameters. The impact of soaking mangrove leaves is at risk of disrupting the physiological activity of fish, then if the waters experience changes in physical and chemical factors, it can produce toxins for various biota. This study aimed to determine the LC50-96 hour value during immersing R. apiculata leaves which have a toxic impact on the test biota. The test biota used was mollyfish (Poecilia sp.) which is usually used as an indicator of environmental change. This study was conducted by determining concentrations including 10, 20, 30, 40, 50% then analyzed using the probit analysis method. The results showed an LC50-96 hour value obtained from the composite results of all concentration treatments from soaking R. apiculata leaves of 559.16 ppm, which means it is included in the low toxic category. However, the percentage of toxicity level showed 6% so that it could induce fish mortality. Keywords:  LC50-96 hour, toxicity, fish mortality
