Abstract

Due to human activities, both domestic and non-domestic, river pollution can occur over time. One of the rivers in Surabaya, which is located in a densely populated area, is Bokor River. Residents use Bokor River for pond activities, so the water's quality must meet these quality standards. This study aims to analyze the suitability of river water quality in Bokor River, Surabaya City, which has met its quality standards for this activity. Water quality measurement is carried out by existing testing with the standard method that is used as a reference in Indonesia. Water quality measurements were determined based on the parameters BOD, COD, DO, TSS, Phosphate (PO4 3-), Nitrate (NO3), and Ammonium (NH4). The measured DO, BOD, phosphate, and ammonia parameters did not meet these quality standards. However, DO parameters in the upstream still meet the quality standard (above 3 mg/L), while after that, they experience a decrease in quality. Meanwhile, nutrient parameters, especially ammonia, do not meet quality standards, as it is known that ammonia can provide toxic properties to fish. In addition, there is an opportunity for eutrophication of this quality. Pollutants entering the Bokor River are point sources and non-point sources, which cannot be located precisely and generally consist of many relatively small individual sources.

Abstract

Kegiatan industri pertambangan pada PT X menghasilkan air limbah domestik yang terdiri dari blackwater dan greywater. Fasilias di PT X yang menghasilkan air limbah domestik adalah hunian pekerja, kantor, kantin, dan binatu (laundry). Sumber greywater berasal hunian pekerja, kantin, dan binatu. Sedangkan blackwater berasal dari toilet hunian pekerja dan kantor. Efluen air limbah masih melebihi baku mutu. Instalasi Pengolahan Air Limbah Domestik (IPALD) dibutuhkan untuk mengolah air limbah domestik agar dapat memenuhi baku mutu. Pada perancangan ini diawali dengan perhitungan debit air limbah domestik dari setiap fasilitas pada PT X, kemudia dilakukan analisis karakteristik greywater dan blackwater. Data debit dan karakteristik air limbah tersebut dijadikan sebagai dasar acuan dalam perhitungan unit IPALD. Unit IPALD yang digunakan yaitu oil and grease trap, bak pengmpul, biofilter anaerob-aerob, bak pengendap, dan desinfeksi. Efisiensi untuk unit oil and grease trap adalah 95%, biofilter anaerob 85% untuk BOD dan COD, biofilter aerob 80% untuk BOD dan COD, bak pengendap 90% dan 75% untuk ammonia dan TSS, dan unit desinfeksi 95% untuk total koliform. Berdasarkan perancangan ini air limbah hasil pengolahan nilainya telah memenuhi baku mutu

Abstract

Penelitian ini membahas tentang indeks kekeringan pada Provinsi Nusa Tenggara Timur berdasarkan data hujan historis dan data hujan proyeksi dengan tujuan untuk dapat mengetahui gambaran kondisi kekeringan pada Provinsi Nusa Tenggara Timur dan dapat memperkirakan resiko kekeringan yang terjadi di wilayah tersebut pada masa mendatang. Metode yang digunakan pada penelitian ini adalah metode Standardized Precipitation Index (SPI), dengan input data curah hujan historis selama 17 tahun (awal tahun 2004 sampai akhir tahun 2020) dan data curah hujan proyeksi selama 30 tahun terakhir abad ke-21 (awal tahun 2071 sampai akhir tahun 2100). Proses perhitungan nilai indeks SPI dilakukan secara otomatis dengan bantuan software SPI Generator v 1.7.5. Hasil nilai SPI berdasarkan data hujan historis menggambarkan kondisi kekeringan di Provinsi NTT masih relatif normal, tetapi ada daerah seperti Kabupaten Belu yang beresiko cukup tinggi mengalami kekeringan. Dari hasil nilai SPI berdasarkan data historis pula, dapat ditentukan periode SPI prioritas yang merupakan periode yang terbaik dalam menggambarkan kondisi kekeringan di lapangan. Kemudian hasil nilai SPI berdasarkan data hujan proyeksi menggambarkan kondisi NTT pada masa mendatang, yang memiliki kondisi (indeks) yang lebih kering dibandingkan dengan indeks SPI berdasarkan data historis.

Abstract

The high production and sufficient calorific value content of the fecal sludge make it can be made as a raw material for producing briquettes. This supports the world's program in an effort to create alternative energy to replace fossil fuels. The purpose of this research is to design a production building and storage of fecal sludge into briquettes in a sewage treatment company so as to minimize the potential hazards of the sludge (accidents in the work placement and the negative impact on the environmenty) as flammable hazardous waste. At the beginning of the design, 3 alternative designs were assessed using the Analytical Hierarchy Process (AHP) method. the chosen alternative is alternative 3 with the proposed redesign of the briquette storage building, production site, and fecal sludge storage area separately, where the sludge storage area which was originally a hangar was converted into a waste impoundment system. The building design criteria for alternative 3 are fire-resistant buildings whose specifications are regulated by the Indonesian National Standard 03-1736-2000 and several other regulations (PERMENLHK No. 12, 2020 and BAPEDAL No. 1, 1995). With a planned storage duration of 1 year, the waste impoundment is designed to cover an area of 2304 m3 of fecal sludge, 72 storage drums for carbonated sludge, and 95 storage drums for fecal sludge briquesttes. In addition, the waste impoundment design is based on the PERMENLHK standard No. 12 of 2020. Waste impoundment can reduce the pH and Total Suspended Solid (TSS) of hazardous waste to below the quality standard threshold. the acidity level of the waste can be neutral to pH 7.79 (threshold 6-9), and TSS down to 86.67 mg/l (threshold 200 mg/l). The results of this study can make a major contribution to the field of hazardous waste management, especially fecal sludge, not only for Indonesia but also for countries that have similar conditions.

Abstract

There is evidence that marine plastic pollution affects marine life and ecological services. The potential hazard to human health from chemical additions in plastics is also present. Although desirable, the recycling of plastics is now limited by the complexity of the materials and chemicals, the limitations of available technologies, and market demands. This study was conducted to discover the challenges and future of marine debris policy. This study takes two locations, Indonesia and Taiwan, which have issued marine debris policies simultaneously. At the same time, the Indonesian and Taiwanese governments 2018 issued a policy to reduce marine debris. Following Presidential Decree Number 83/2018 concerning Handling Marine Debris, the Government of Indonesia published a National Action Plan for Handling Marine Debris for 2018–2025. Following this law, the Indonesian government agreed to handle 70% of the solid trash generated within eight years between 2018 and 2025, eliminate marine debris by 70%, and reduce solid waste by 30%. In Taiwan, the "Action Plan of Marine Debris Governance, " issued in 2018 by this alliance and the EPA, contains a schedule for the phase-out of four single-use plastic items (plastic bags, straws, utensils, and takeaway cups). Source reduction, prevention and removal, monitoring and surveying (including research), and outreach and public involvement are the four objectives of this action plan. Although implementing the policy is different, the objectives carried out in Indonesia and Taiwan are the same: reducing waste from sources and increasing community participation in action plan programs.

Abstract

Natural rubber is one of the agricultural products in exceptionally high demand for industrial materials. In Indonesia, rubber is a major plantation crop grown all across the country. This research seeks to use the LCA technique, but its primary objective is to examine the consequences of the crumb rubber industry. Using sulfuric acid causes the emission of roughly 11,94705 kg equivalent of the gas sulfur dioxide into the environment. In contrast, using isoprene as a base material causes the emission of approximately 1090 kg equivalent to the gas carbon dioxide. Coal-derived energy accounts for up to 719,748 MJ, or 199,930 kWh, and is the critical focus in the quest for alternative energies. Because the macerator, creeper, hammer mill, and drying machine take 199.93-kWh of electricity to operate.

Abstract

Drainage is one way of removing unwanted excess water in an area and dealing with the effects of excess water in the system. When the rainy season comes, there are almost floods or puddles on urban roads. The large population also makes the volume of drainage channels fill up quickly, while the drainage capacity tends to decrease due to rainwater (erosion) and sedimentation. Meteorological Street, Laut Dendang Village, Percut Sei Tuan sub-district, Deli Serdang Regency, is one of the villages that is frequently flooded every time it rains. On these issues, the researcher highlights the importance of evaluating the Deli Serdang Regency's drainage system along Meteorological Road to anticipate when the rainy season comes. The general exponential method can determine whether the existing drainage volume can still accommodate terrestrial run-off and domestic wastewater in the next 30 years and calculate the population growth. Based on the research results from rainfall data obtained from Meteorology Road, the rainfall intensity value for the last ten years (2010 - 2019) was 10.538 mm/day. Thus, the amount of discharge flowing in the drainage channel (Qplansning) is equal to 0.832 m3/sec, while the planned Q for the next ten years is 0.874 m3/sec, for the next 20 years is 0.953 m3/sec, and 30 years into the future. front is 1.111 m3/sec. Based on the calculation results, Qplans exceeds Qeksisting. Therefore, a new channel plan is needed.

Abstract

Due to the Covid-19 pandemic, the impact of the lockdown on the water quality of major rivers due to restrictions on activities within the country will have an effect. This research compared the Cimalaya Watershed water quality index values before and during the Covid-19 pandemic. River status was conducted using STORET and Pollution Index based on 2019 and 2020 river quality data. Calculations for each method use the same amount of data and parameters, including TSS DO, BOD, COD, TP, Fecal Coliform, and Total Coliform. The results showed a decrease in concentration for water quality parameters in 2020 or during the Covid-19 pandemic compared to 2019. The parameters that experienced a reduction included TSS, DO, BOD, and COD. But besides that, there has been an increase in water quality parameters in 2020, namely the parameters TP, Fecal Coliform, and Total Coliform. The average STORET and Pollution Index values in 2020 indicated that the river is getting moderately polluted than in 2019. This research can be a preliminary study, but using more parameters and methods will make the analysis more comprehensive.
