Abstract

Aim: The purpose of this study was to determine the efficiency and characteristics of pig wastewater treatment. This was to be achieved using ABR with the addition of effective microorganism4 (EM4) as a bio-activator during the startup process (R1) and without EM4 (R2). Methodology and Results: Piggery wastewater is poured into ABR with 12 hours HRT (hydraulic retention time), though it is reduced to 6 hours after the concentration is stable. The COD removal efficiency at 12 hours HRT was 60% (R1) and 51% (R2). However, the results did not change significantly, since the 6 hours HRT COD efficiency was 57.8% (R1) and 51.3% (R2). The biomass growth rate at R1 is faster than R2 with Food to Microorganism Ratio (F/M) 0.4-0.89 (R1) and 0.68-1.38 (R2) while the yield of methane gas formation was 0.25-0.28 L-CH4/g-COD. Conclusion, significance, and impact study: COD effluent is the total organic material present in the piggery wastewater effluent, which is discharged into water bodies without meeting the set quality standards. This damages the quality of water bodies. The wastewater treatment needs to be prioritized to meet quality standards of COD effluent. Also, the addition of EM4 to the activated sludge reactor improves the COD removal efficiency and biomass growth, though advanced treatment is still needed for piggery wastewater.

Abstract

Marine debris is an important problem because it can directly impact the environment and public health. Good waste management is required to manage coastal waste. One of the coasts on the Indonesian border, which is experiencing an increase in waste in the ocean, is Lengkang Island. This study aims to evaluate the need for waste management facilities based on waste generation and composition. This research was carried out quantitatively and qualitatively, and the generation and composition of the waste were measured by field observations. Qualitatively, this was accomplished through a literature review. The average amount of waste in the marine waters of Lengkang Island is 19.5±3.7 kg/m2. As much as 64% of the waste thrown into the sea is plastic, and the remainder consists of paper/cardboard, rubber, and wood. Managed waste is usually illegally stockpiled, collected in temporary shelters (tempat pembuangan sampah/TPS), and then burned. These problems must be resolved by planning from source, collection, and transportation to processing at the final processing site (tempat pemrosesan akhir/TPA).

Abstract

Pengolahan air limbah domestik yang saat ini umum digunakan adalah kolam stabilisasi yang terdiri dari anaerob, fakultatif, dan aerobik. Di dalam prosesnya setelah melalui kolam stabilisasi dapat dapat ditampung melalui reservoir. Dalam proses pengolahan dengan proses kolam stabilisasi kehadiran gulma seperti duckweed dapat memban meningkatkan efisiensi penyisihan nutrient. Tujuand ari studi ini adalah untuk mengevaluasi kehadiran duckweed pada air limbah dan potensi pemanfaatannya di sistem kolam stabilisasi. Studi ini dilakukan dengan cara observasi lapangan dan studi literatur. Sistem kolam stabilisasi terdiri dari 3 sel: sel IA dan sel IB, sel IIA dan IIB, dan sel III. Sel I terdiri dari dua bagian yaitu sel IA dan sel IIB. Duckweed dalam sistem hanya tumbuh di kolam sel IB, sel IIA dan reservoir. Sesuai dengan karakteristiknya, alga memang sudah seharusnya tumbuh di sel IIA. Sel IIA adalah kolam fakultatif, yang memiliki daerah aerobik dan daerah anaerobik. Saat pagi dan sore hari alga tidak muncul ke permukaan dan air terlihat bening. Alga yang muncul di reservoir didominasi oleh alga kelas Chlorophyta karena memiliki warna hijau. Duckweed dapat digunakan sebagai pakan ternak seperti ikan, sapi, domba, kuda dan babi. Selain itu duckweed juga daapat dijadikan sumber energi dengan teknologi termokimia telah banyak digunakan untuk menghasilkan produk bio-minyak, arang dan gas.

Abstract

The urban center of Batam faces recurrent water crises. The introduction of the Bengkong Sadai Wastewater Treatment Plant (WWTP) offers a potential solution, converting domestic wastewater into reusable water, thereby addressing scarcity concerns. This research provides a comprehensive SWOT analysis of the WWTP, aiming to understand its potential for ensuring sustainable water management in Batam. We identified that while the WWTP capitalizes on state-of-the-art infrastructure, making a notable contribution to water reclamation and organic fertilizer production, it also confronts challenges like community engagement and operational complexities. Based on the analysis, the study emphasizes the criticality of proactive maintenance, robust stakeholder collaboration, and the need for a forward-thinking approach. This work sheds light on Batam's endeavors and offers a blueprint for other urban locales grappling with similar challenges.

Abstract

This research examines the escalating environmental degradation observed along the Tanjung Uma coastline, juxtaposing its unique challenges with the global narrative of declining coastal health. As a thriving marine ecosystem, Tanjung Uma has recently experienced considerable ecological decline, cascading effects on local biodiversity, community livelihoods, and socio-cultural dynamics. The study provides a granular understanding of the region's strengths, weaknesses, opportunities, and threats by combining a comprehensive literature review and a SWOT analysis. Findings highlight the dire state of the marine environment, driven by factors such as pollution, waste accumulation, and broader implications of climate change. However, the research also underscores the potential for regional cooperation, community engagement, and leveraging traditional knowledge as avenues for sustainable intervention. As a microcosm of global coastal challenges, Tanjung Uma's case offers insights that can inform broader strategies for marine conservation and community resilience.

Abstract

Water is a human need to carry out activities ranging from daily essentials to agricultural needs and others. Domestic wastewater must meet physical, chemical, and biological requirements so that humans cannot be polluted by the water, especially the water around the Pasir Panjang Village area in Batam, Riau Islands. This study aims to determine the potential use of water hyacinth for environmental health. This research was conducted by direct observation and measurement of water quality by grab sampling. Observation results show that not all residents use septic tanks as wastewater treatment results from daily activities. Some residents drain their wastewater directly into water bodies or surrounding land, resulting in decreased environmental aesthetics. Water quality testing for nutrient parameters shows that the quality standards have been met. However, further measurements are needed for total nitrogen and phosphate. Besides that, it also causes a population explosion of water hyacinth. In addition to the ability to treat water hyacinth waste, its economic potential is also analyzed. The growth of water hyacinth is sufficient and fulfills its capacity, and water hyacinth can be used for various crafts that can improve the community's welfare.

Abstract

The wastewater treatment plant (WWTP) in the Nusa Dua area has implemented a stabilization pond to reduce organic matter and nutrients. Because it has been operating since 1980, it is necessary to evaluate the existing conditions. The aim of this study was to determine the percentage of organic and nutrient reduction from the WWTP system. Organic removal in the form of BOD and COD parameters were 71.84% and 75.11%, respectively. Meanwhile, nutrient parameters in the form of NH3-N, TN, and TP have a percentage of 83.64%; 59.41%, and -375.81%, respectively. TP is the only parameter that has increased, causing a problem which is caused by the explosion of algae population in the reservoir. TP allowance should be a concern in choosing advanced treatment.

Abstract

Postur kerja yang tidak sesuai bisa menjadi pemicu timbulnya keluhan fisik pada pekerja, terutama jika dilakukan dalam waktu lama dan berulang. Penelitian ini bertujuan untuk menganalisis postur kerja operator dalam proses penggerindaan ulir pada pipa OCTG dengan menggunakan metode Rapid Entire Body Assessment (REBA), serta perbaikan ergonomi yang dibutuhkan untuk mengurangi potensi risiko. Penilaian dilakukan menggunakan metode REBA dengan pendekatan deskriptif semi-kuantitatif. Data diperoleh dari observasi langsung di lapangan, dokumentasi foto, pengukuran sudut tubuh menggunakan AutoCAD, dan wawancara dengan dua orang operator. Hasil awal menunjukkan bahwa posisi kerja operator termasuk dalam kategori risiko sedang, dengan skor REBA sebesar 7. Untuk mengurangi risiko tersebut, dudukan gerinda dibuat yang disesuaikan dengan tinggi badan operator. Setelah perbaikan dilakukan, skor REBA menurun menjadi 2, yang menunjukkan risiko rendah. Perubahan terlihat jelas terutama pada posisi punggung, leher, dan kaki yang menjadi lebih tegak dan seimbang. Hasil ini menunjukkan bahwa perbaikan sederhana yang memperhatikan kenyamanan postur kerja dapat berdampak besar terhadap kesehatan dan kenyamanan pekerja, serta membantu menciptakan lingkungan kerja yang lebih baik.
