Abstract

Pembangunan berkelanjutan telah menjadi salah satu capaian penting di beberapa perguruan tinggi di Indonesia termasuk di Universitas Pembangunan Negeri (UPN) Veteran Jawa Timur. Program tersebut menuntut kampus untuk melakukan pengelolaan sampah yang efektif dan berkelanjutan, sehingga analisis sistem tata kelola sampah perlu dilakukan. Penelitian ini berfokus pada sistem pengelolaan sampah di Fakultas Teknik, UPN Veteran Jawa Timur. Pengambilan data meliputi berat, volume, komposisi, dan sistem pewadahan sampah. Data timbulan dan pewadahan sampah dievaluasi berdasarkan pada standar yang berlaku di Indonesia. Hasilnya menunjukkan bahwa jumlah tempat sampah yang ada di Fakultas Teknik, UPN Veteran Jawa Timur belum dapat menampung timbulan sampah harian. Selain itu, sekitar 24% wadah tidak sesuai dengan standar yang berlaku. Oleh karena itu, diperlukan peningkatan fasilitas dan sistem pengelolaan sampah terutama dalam proses pewadahan.

Abstract

Penggunaan oli bekas sebagai bahan tambahan senyawa pestisida untuk mengusir hama pada pertanian padi di Kabupaten Karawang berpotensi menyebabkan kontaminasi tanah oleh hidrokarbon yang bersifat toksik. Salah satu upaya pemulihan yang dapat diterapkan adalah bioremediasi menggunakan teknik pengomposan yang memanfaatkan jerami pasca panen dan kapur dolomit sebagai bahan baku kompos. Penelitian sampel bersifat eksperimen, dimana tanah diambil pada sawah seluas 0,15 ha sebanyak 9 (sembilan) titik pada kedalaman 0,00-30,00 cm yang kemudian dikomposit menjadi satu. Proses pengomposan dilakukan dengan mencampurkan tanah dan bahan baku kompos (rasio 1:1, b/b) menggunakan 5 (lima) variasi yaitu kontrol tanah (tanah 4.500 g), kontrol jerami (4.500 g), A (tanah:jerami:dolomit sebanyak 4.500 gr: 4.410 gr: 90 gr), B (tanah:jerami:dolomit sebanyak 4.500 gr: 4.275 g: 225 g): dan C (tanah:jerami:dolomit sebanyak 4.500 g: 4.050 g: 450 g) dengan 3 (tiga) ulangan selama 30 hari. Hasil penelitian menunjukkan bahwa nilai pH, suhu, dan kelembaban semua rekator berada pada rentang optimal yaitu 5,07-6,43; 33,00-40,00°C; 50,00-70,00%. Kondisi tersebut mendukung terjadinya biodegradasi bahan organik melalui kadar hidrokarbon, dimana penurunan tertinggi ditemukan pada variasi C sebesar 66,22%.

Abstract

Anaerobic Baffled Reactor (ABR) systems have only been utilized to reduce pollutant compounds in wastewater. Anaerobic conditions in ABR can double as an anode chamber in Microbial Fuel Cells (MFCs) which require anaerobic conditions. This study aims to test the ability of COD and TSS removal in tofu wastewater and the potential electricity generated from a combination unit of ABR and MFCs. The experiment was conducted on a laboratory scale using a continuous system for 96 hours. ABR reactor was made consisting of 5 compartments, where the second compartment was installed anode for MFCs. The cathode chamber of the MFCs system was made separate from the ABR reactor and filled with electrolyte solution. The anode chamber in the ABR and the cathode chamber are connected by a salt bridge. Electrodes used in MFCs are zinc as anode and copper as cathode. The removal of pollutants in tofu wastewater reached 55.85% for COD and 88.68% for TSS. The electrical potential of MFCs increases along with the increase of organic matter removal in wastewater. The electric voltage generated reached 0.94 V and electric current 0.40 mA. The power density generated in this MFCs system reached 94 mW/m².

Abstract

Climate change, driven by greenhouse gas (GHG) emissions, necessitates transformative shifts in the global energy sector. This is particularly critical for Indonesia, which continues to rely heavily on fossil fuels. In this context, Combined Cycle Gas Turbine (CCGT) power plants have emerged as a potential transitional technology, offering higher efficiency and lower operational emissions than coal-fired power plants. This study employs a Life Cycle Assessment (LCA) framework to analyze the carbon footprint of a CCGT power plant in Indonesia, providing a comprehensive evaluation of its environmental impacts across all stages—from fuel extraction to plant operation and electricity distribution. The findings reveal that the natural gas combustion process and upstream gas production are the primary contributors to the total emissions, accounting for approximately 0.473 kg CO₂-eq/kWh and 0.26 kg CO₂-eq/kWh, respectively. Despite these emissions, the CCGT plant demonstrates a significantly lower carbon footprint compared to coal-fired power generation. The study also identifies key strategies for mitigating emissions, including enhancing methane leak detection technologies, optimizing natural gas transportation, and integrating Carbon Capture and Storage (CCS). Based on these findings, we provide technical and policy recommendations to support a sustainable energy transition in Indonesia.

Abstract

River water pollution has now become a serious problem for society with population growth. The development of various industries and pesticides usage. One of the rivers in Lamongan, namely Kaliotik is heavily polluted. One of the rivers in Lamongan, namely Kaliotik is heavily polluted. Therefore, the research aim is to analyze the distribution of Kaliotik River water quality pollution zones. The research type is a quantitative descriptive analysis, with the research design used the true experimental time series design. Identification of river pollution zones along the Kaliotik river is based on the self-purification zone. contamination zone is identified based on the content of BOD, COD, DO as well as microscopic and biometric tests of the diversity of water organisms. River water quality assessment using Biotilics is carried out by calculating the diversity of family types, the diversity of EPT types, percentage of EPT abundance, and the Biotilic Index. The results of the research showed that Station I obtained a biotylic index of 2.45; Station II obtained a biotylic index of 2.66; station III obtained a biotylic index of 2.82; Station IV obtained a biotylic index of 2.82 and Station V obtained a biotylic index of 2.97. From these results it can be concluded that the Kaliotik river is heavily polluted and in a polluted zone.

Abstract

The climate crisis and increasing intensity of natural disasters demand an integrated solution encompassing both structural and social dimensions. The construction industry, particularly the use of Portland cement (OPC), accounts for approximately 7–8% of global carbon emissions, and the vulnerability of infrastructure to disasters further elevates risks for communities. This study addresses a gap in the literature by integrating low-carbon material innovations, specifically geopolymer concrete, with community-based preparedness strategies within the framework of disaster risk mitigation and IPCC climate policy. A systematic literature review was conducted on 35 selected publications from Scopus, ScienceDirect, Google Scholar, and IPCC AR6 reports. Findings indicate that geopolymer concrete can reduce carbon emissions by up to 97%, exhibits high resistance to heat, earthquakes, and corrosive environments, and is suitable for infrastructure in disaster-prone areas. Social strategies such as education, evacuation drills, and strengthening local institutions have proven effective in enhancing community resilience. This study proposes a “dual-resilience” framework that combines structural strength with social capacity, which is relevant for mainstreaming in sustainable development policies in Indonesia.

Abstract

This paper examined the wastewater production attributed to the solvent-based cooking oil extraction using Aspen Plus simulation facilitated which has been confirmed by experimental results. Distillate condensates that had remaining solvents as well as free fatty acids (FFAs) were identified as waste streams. Three feedstocks were tested, Crude Nyamplung Oil (CNO), high-FFA Crude Palm Oil (CPO-acid), and regular Crude Palm Oil (CPO-regular). CNO generated 0.288 t/h of hexane and methanol traces of wastewater, whereas CPO-acid (1.338 t/h) and CPO-regular (1.419 t/h) contained ethanol. The stoichiometric oxidation was used to estimate chemical oxygen demand (COD), whereas FFA content was used to determine oil and grease (O&G). The COD values of untreated streams were 293.236 mg/L (CNO), 2511.39 mg/L (CPO-acid), and 1662 mg/L (CPO-regular), which were higher than the Indonesian standard (350 mg/L). Oil and Grease (O&G) values of the untreated waste streams were not met the standards. Solvent based processes are less polluting as compared to refinery effluents (COD >15000 mg/L, O&G 4000mg/L), yet not in compliance with COD. Solvency and FFA value to biodiesel or PFAD are suggested to be enhanced to decrease the environmental burden.
