Abstract

UNICEF secara alamiah membuat referensi pada situasi masalah udara dan sanitasi yang mengganggu dan menjadikan aman masyarakat di India sebagai organisasi yang membantu membangun perlindungan bagi masyarakat dan juga memandang hal ini sebagai suatu keharusan. Tujuan dari Penelitian ini adalah untuk berkontribusi UNICEF dalam upaya program WASH (Water, Sanitation, and Hygiene) untuk mengatasi masalah udara dan sanitasi di India. Dengan menggunakan penelitian kepustakaan, metodologi penelitian kualitatif deskriptif diterapkan. Hasil penelitian menunjukkan bahwa UNICEF telah melakukan berbagai upaya luas untuk memastikan pelaksanaannya program WASH secara optimal, termasuk dukungannya terhadap sektor pendidikan. Selain itu, UNICEF berperan penting sebagai wadah kolaborasi, komunikasi, dan pengembangan perencanaan serta pelaksanaan program bersama. Diskusi yang diselenggarakan oleh UNICEF bersama LIXIL, UNILEVER, dan Xylem menghasilkan beberapa solusi untuk mengatasi kekurangan dalam pelaksanaan program MENCUCI. Selain itu, UNICEF juga bertindak sebagai aktor independen yang mengembangkan program dan kemitraan untuk menangani isu sanitasi dan udara di India. Terlihat jelas bahwa berbagai konsep kebijakan didasarkan pada kerangka kerja yang dibuat oleh UNICEF sendiri tanpa tekanan dari pihak lain. Dalam praktiknya, UNICEF berhasil menghalangi kebijakan para anggotanya agar fokus pada kelangsungan hidup anak-anak, khususnya terkait akses terhadap air bersih dan sanitasi.

Abstract

The province of Southwest Papua is characterized by its mountainous terrain, which influences the region's precipitation patterns. The typical rainfall distribution in this area takes on an "A" shape, exhibiting a peak of highest rainfall in the middle of the year. This pattern is observed in regions shaped by local features such as topography and wind systems, with significant rainfall typically occurring in June and July. To enhance the accuracy of climate forecasting, Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG) has revised its climatology data, updating the Normal Rainfall figures from the period 1981-2010 to those from 1991-2020. This updated framework serves as a reference for identifying rainfall types across Indonesian territories, particularly in eastern Indonesia and Southwest Papua. Analysis of rainfall data collected from various monitoring stations in the Southwest Papua region for the years 2020 to 2024 reveals the existence of two distinct rainfall patterns: Local type 1 observed at the Majener, Malagusa, Klasmelek, DEO Sorong Meteorological Station and Sorong Geophysics Station, and Local type 2 noted at the Walal, Klamalu, Mariyai, and Waisai rain posts. The most intense rainfall peaks typically occur in July and August, ranging from 300 - 600 mm per month, whereas the lowest precipitation levels are generally recorded in February, with values between 0 - 100 mm per month.

Abstract

Good environmental quality is essential to support the optimal life and development of communities. Hu’u District, Dompu Regency, possesses abundant natural resource potential; however, human activities, especially agriculture, can affect the local environmental conditions. This study aims to evaluate the environmental health status in Hu’u District, focusing on groundwater quality, soil, and air parameters based on the standards outlined in the Regulation of the Minister of Health of the Republic of Indonesia Number 2 of 2023. Sampling conducted during the wet season (February–March 2023) at nine groundwater locations, ten soil locations, and five air sampling sites around villages in Hu’u District. Physical, chemical, and microbiological analyses were performed to assess water and soil quality. The results showed that several groundwater parameters, such as color, turbidity, and total dissolved solids (TDS), exceeded the established thresholds, likely due to natural organic matter, mineral dissolution, and agricultural activities. Total coliform bacteria were detected at several points, indicating potential domestic waste contamination, although Escherichia coli was not found. Concentrations of heavy metals include Barium (Ba), Copper (Cu), and Zinc (Zn), in some soil locations exceeded quality standards, suspected to be associated with agricultural activities and active geological characteristics. Additionally, air quality for chemical parameters is classified as good, but CO concentrations need to be prioritized for monitoring as its potential to increase due to the burning of agricultural waste activities. These findings provide an important basis for developing adaptive environmental management policies in Hu’u to maintain ecosystem sustainability and community quality of life.

Abstract

Domestic wastewater produced by industrial areas, although not directly derived from the production process, still has the potential to cause environmental pollution if not properly treated. This waste generally contains organic pollutants, nutrients, oil and fat, and pathogenic microorganisms. If not properly treated, waste discharge into water bodies can increase BOD, COD, TSS, Oil and Greaset, Ammonia, and Total Coliform levels, which have an impact on water quality degradation. This study aims to evaluate the effectiveness of the performance of the Wastewater Treatment Plant (WWTP) at PT MGS Menggung PT Pertamina EP Cepu by utilizing primary data through field observations and interviews, as well as secondary data in the form of laboratory test results for the period July–December 2024. The evaluation was carried out on six wastewater quality parameters, namely Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Oil and Grease, Ammonia, and Total Coliform. The analysis results show that the average BOD reduction efficiency is 42.8% and COD is 52.31%, which is considered quite effective. Conversely, the reduction efficiency of TSS (38.80%) and Total coliform (39.32%) was still less than optimal. This low efficiency indicates the need for improvements in the sedimentation and disinfection units. Therefore, it is recommended to add a coagulation-flocculation process and optimize the chlorination system to improve WWTP performance so that the treated product meets domestic wastewater quality standards as stipulated in applicable regulations

Abstract

Batik wax waste and oyster mushroom baglog waste have high potential as raw materials for biomass-based alternative energy. Batik wax waste contains carbon with a calorific value of approximately 42 MJ/kg, while mushroom baglog waste has a high lignocellulose content that functions as a natural adhesive. This study aimed to determine the effect of varying the composition of batik wax waste on the quality and emissions of pyrolyzed mushroom baglog waste-based bio-coke. Mushroom baglog waste was pyrolyzed at 350–400°C for three hours, then mixed with batik wax waste in varying concentrations of 10%, 20%, 30%, 40%, and 50%, with a total mass of 100 grams each. The pressing process was carried out using a Leybold-Heraeus Compact MDP 10-1 machine with a pressure of 2 tons. Bio-coke characterization included proximate tests (moisture content, ash content, volatile matter, and fixed carbon), calorific value using a Parr-6400 Calorimeter, and exhaust emissions using a KOENG KEG-500 Automotive Gas Analyzer. Results showed that increasing the composition of batik wax waste increased the calorific value from 20.37 MJ/kg (P10) to 27.31 MJ/kg (P50). Ash content decreased from 30.2% to 24.88%, while volatile matter increased from 16% to 26.5%. CO and HC emissions decreased significantly, approaching zero at mixtures of ≥20%. Thus, the addition of batik wax waste can improve energy efficiency and reduce pollutant emissions, making pyrolysis-derived bio-coke suitable for development as an environmentally friendly fuel to replace firewood in the small industrial sector.

Abstract

Expired pharmaceutical waste is increasingly recognized as a significant environmental pollutant due to its persistent active compounds that can contaminate water systems. Hospitals generate substantial amounts of pharmaceutical waste, including unused liquid and solid drugs. This study aims to utilize expired drugs as raw material for adsorbent production through carbonization and chemical activation processes, thereby offering a sustainable solution for hospital wastewater treatment. The methodology involved collecting expired drugs, subjecting them to high-temperature carbonization, and applying chemical activation to enhance surface area and adsorption capacity. Adsorption tests were conducted on hospital wastewater samples, focusing on COD, BOD, and heavy metal parameters. Results demonstrated that drug-derived adsorbents reduced COD and BOD levels by up to 60% and showed significant efficiency in heavy metal removal. Compared to commercial adsorbents, the performance of expired drug-based adsorbents was competitive, while also being cost-effective and environmentally friendly. This research highlights the dual benefits of reducing pharmaceutical waste and providing an alternative adsorbent material for wastewater treatment. The findings support the concept of circular economy in pharmaceutical waste management, emphasizing resource recovery and environmental sustainability.

Abstract

Pharmaceutical compounds discharged into aquatic environments, such as antibiotics and analgesics, are resistant to natural degradation and pose risks including microbial resistance and ecological imbalance. This study investigates the application of nanotechnology-based photocatalysts, specifically TiO₂ nanostructures, for the degradation of pharmaceutical pollutants in wastewater. The photocatalyst was synthesized using a sol-gel method and characterized by XRD and SEM to confirm its crystalline structure and morphology. Degradation experiments were conducted on paracetamol and selected antibiotics under UV irradiation. Results indicated that TiO₂ nanostructured photocatalysts achieved up to 75% degradation within 120 minutes. The photocatalytic mechanism involves the generation of hydroxyl radicals that attack the chemical bonds of pharmaceutical compounds, producing simpler and less harmful byproducts. Enhanced degradation efficiency was observed with increased light intensity and larger surface area of the photocatalyst. Compared to conventional treatment methods, this approach is energy-efficient and does not generate hazardous residues. The findings highlight the potential of nanotechnology-based photocatalysis as a sustainable solution for pharmaceutical wastewater treatment, aligning with green technology initiatives in environmental engineering.

Abstract

Pharmaceutical waste discharged into aquatic environments can significantly deteriorate water quality and disrupt ecosystems. Even at low concentrations, active pharmaceutical compounds may induce physiological changes in aquatic organisms and contribute to the emergence of antibiotic resistance. This study aims to analyze the impact of pharmaceutical waste on water quality and evaluate bioremediation using indigenous microorganisms as a sustainable treatment approach. Water samples contaminated with pharmaceutical residues were collected near healthcare facilities. Parameters such as pH, dissolved oxygen (DO), chemical oxygen demand (COD), and pharmaceutical concentrations were measured. Indigenous microorganisms capable of metabolizing pharmaceutical compounds were identified and applied in bioremediation experiments over 14 days. Results revealed a 50% reduction in pharmaceutical residues, accompanied by improved water quality indicators, including increased DO and decreased COD. The microorganisms demonstrated adaptability to polluted environments and utilized pharmaceutical compounds as energy sources. These findings underscore the potential of bioremediation as an eco-friendly strategy for pharmaceutical wastewater treatment. The study contributes to the development of sustainable waste management practices, emphasizing the role of local microbial resources in mitigating environmental pollution.
