Abstract

The Drinking Water Safety Plan (WSP) is a systematic approach to ensuring the quality and safety of the community's drinking water. With increasing challenges such as contamination of raw water sources, climate change, and population growth, the development of WSPs is critical to protecting public health from the risks of waterborne diseases. In addition, the lack of guidance in the development of RPAMs indicates that clear documents and training are critical to the successful implementation of WSPs. The process of developing a WSP document involves four main stages: preparation, risk analysis system, management and communication, and feedback. Each stage is designed to help identify and manage risks that may affect the quality of water the community receives. Stakeholder involvement and clear guidance are critical to the successful implementation of the WSP. Through this approach, the WSP is expected to increase community access to safe and quality drinking water in line with the Sustainable Development Goal (SDG) 6.1 target to achieve universal and equitable access to safe and affordable drinking water for all by 2030.

Abstract

The global climate change phenomenon is prompting initiatives aimed at transitioning energy sources towards more sustainable pathways. Pyrolysis technology offers significant potential in the conversion of biomass and plastic waste into alternative energy sources. The objective of this literature review is to analyze the effect of feedstock type on pyrolysis product characteristics and its potential as an energy source. The results of the literature study indicated that the feedstock from biomass possessed a lower calorific value in comparison to waste composed of polymer compounds. The pyrolysis process yields three primary byproducts: char, bio-oil, and gas. Char can be utilized as a solid fuel, such as briquettes. The processing of bio-oil into liquid fuel, bioethanol, is a viable option. The pyrolysis gas is a versatile material that can be utilized as a fuel for stoves and generators. Pyrolysis, a promising technology, has the potential to convert biomass and plastic waste into alternative energy. The type of feedstock employed is a critical factor in determining the quality and quantity of pyrolysis products. Through process optimization and technological development, pyrolysis has the potential to play a substantial role in reducing reliance on fossil fuels and addressing environmental concerns.

Abstract

The streaming current monitor (SCM) is an instrument used to measure small particles suspended in water and ensure their stability. It can be operated in real time to detect changes in water quality and temperature. The SCM provides a continuous flow that can quickly and accurately measure changes in water quality. In the Water Treatment Plant (WTP), it supplements conventional laboratory tests, enabling longer testing times and reducing the cost of chemical materials. The SCM also provides real-time data analysis which is logged in the Supervisory Control and Data Acquisition (SCADA) system. Integrating this technology reduces the need for manual decision-making and minimises human error, offering flexibility and control to operators. SCM technology was developed at IPA Sadu in Soreang to improve operational efficiency. It also uses other real-time monitoring instruments, such as those measuring pH, turbidity and chloride. These instruments are integrated into the SCADA data management system, enabling data collection and monitoring of potential issues and enhancing the efficiency and accuracy of the water quality control process.

Abstract

Rapid population growth in urban areas of Indonesia, particularly in satellite cities such as City X, has led to an increase in domestic wastewater generation. This condition causes negative impacts on the environment, especially on the quality of water bodies and public health. Limited land availability, uneven distribution of sanitation services, and fluctuations in pollutant loads are major challenges in domestic wastewater management. To address these issues, the construction of a Wastewater Treatment Plant (WWTP) is planned with characteristics of small land footprint, low operational costs, and the ability to accommodate fluctuating pollutant loads. The WWTP service area is planned to cover 591,514 m², with the projected population at the end of the planning period reaching 9.072 people in 2088. Wastewater entering the WWTP system has the following characteristics: BOD 162 mg/L, COD 268 mg/L, TSS 210 mg/L, ammonia 48,57 mg/L, and total coliform 22 × 10⁸ MPN/100 mL. The proposed treatment design alternatives include: a bar screen with dimensions of 2,4 m × 0,5 m × 0,5 m, grit chamber 13,5 m × 10 m × 1 m, grease trap 8,5 m × 2,82 m × 1,19 m, equalization tank 24 m × 24 m × 2 m, MBBR 20,57 m × 4,57 m × 4,57 m, and a disinfection unit 29,76 m × 1,25 m × 3 m. The treated wastewater is expected to comply with domestic wastewater quality standards in accordance with the Regulation of the Minister of Environment and Forestry No. 68 of 2016. The total land area required for this WWTP is 856,6 m².

Abstract

Trihalometan (THM) merupakan produk samping disinfksi yang terbentuk akibat relasi antara klorin dengan bahan organik alaa (natural organic matter/NOM) pada sumber air baku air minum, dan keberadaannya menjadi perhatian penting karena berpotensi menimbulkan dapat kesehatan jangka panjang. Penelitian ini bertujuan untuk mengkaji dan membandungkan karakteristik, faktor dominan, serta tingkat konsentrasi pada system penyediaan air minu di wilayah tropis dan non-tropis melalui pendekatan studi literatur. Metode yang digunakan adalah literatur review dengan penelusuran artikel ilmiah terbitan sepuluh tahun terakhir yang membahas konsentrasi THM, prekursor pembentukkannya, serta pegaruh kondisi lingkungan dan kualitas air baku. Hasil kajian menunukkan bahwa pembentukan THM secara umum didominasi oleh keberadaan bahan organik terlarut, khususnya fraksi humik dan aromatic yang direpresentasikan oleh parameter DOC, UV254, SUVA, seta chromophoric dissolved organic matter (CDOM). Di wilayah tropis seperti, Indonesia, Thailand, Sri Langka, dan Brezil konsentrasi THM cenderung tinggi dan bervariasi, dengan pebentukan hampir 1.000 µg/L dengan karakteristik lahan gambut. Kondisi ini dipengaruhi oleh tingginya kandungan NOM, dan suhu lingkungan yang tinggi, serta kualitas air baku yang terpapar aktivitas antropogenik. Wilayah non tropis seperti Eropa dan Amerika Utara, konsentrasi THM umumnya lebih rendah dan realtif lebih terkendali, meskipun masih dipengaruhi oleh kualitas sumber air dan praktik pengolahan.

Abstract

Peningkatan kapasitas produksi Crude Palm Oil (CPO) di PT XYZ, yang mencapai 792.000 ton TBS pada tahun 2024, berimplikasi pada melonjaknya kebutuhan air bersih untuk unit utilitas seperti boiler dan refinery dan kebutuhan domestik. Di sisi lain, pemanfaatan air permukaan dan air tanah menghadapi kendala polusi, salinitas tinggi, serta regulasi lingkungan yang ketat (UU No. 32/2009). Penelitian ini bertujuan untuk merencanakan sistem desalinasi Seawater Reverse Osmosis (SWRO) sebagai solusi pemenuhan kebutuhan air industri yang mengalami peningkatan. Metode penelitian menggunakan pendekatan perencanaan teknik dengan bantuan analisis Multi Criteria Decision Analysis (MCDA) untuk pemilihan unit pre-treatment. Berdasarkan hasil analisis MCDA, konfigurasi pre-treatment yang dipilih meliputi unit koagulasi-flokulasi, sedimentasi, filtrasi, dan cartridge filter guna melindungi membran SWRO dari fouling dan scaling.
