Domestic wastewater management on university campuses is a crucial aspect of supporting sustainable development. As a center of academic and non-academic activities, Universitas Andalas produces a significant volume of domestic wastewater from the daily activities of its 31,549 academic community members as of 2023. One of its key facilities is the Shared Lecture Building complex, consisting of 10 buildings (A–J), which applies a separated wastewater management system: greywater from floor drains and washbasins is discharged directly into the nearest drainage, while blackwater from toilets is channeled into septic tanks. Currently, Universitas Andalas lacks comprehensive data and planning related to its Domestic Wastewater Management System (SPALD), despite Government Regulation No. 22 of 2021 requiring domestic wastewater to be safely treated before discharge into water bodies. This study aims to evaluate and provide recommendations for an effective and efficient SPALD, specifically for the Shared Lecture Buildings. The method used involves field observations to collect data on the existing conditions. The results show that of the 19 septic tanks observed, 36.84% did not meet vent pipe requirements, 21.05% did not follow the appropriate desludging interval, and 42.11% lacked inspection openings. Furthermore, the effluent from these septic tanks is directly discharged into drainage channels without further treatment, posing a risk of contamination to surrounding water bodies and groundwater. This study is expected to serve as a basis for improving septic tank systems in accordance with SNI 2398:2017, so that wastewater management at Universitas Andalas can operate more optimally and sustainably.

All attempts have been taken by majority nations to reduce and invent the greenhouse gases (GHG) emission, but none of them provide any quantitative framework to assess ecosystem capacity for carrying carbon. To measure ecosystem boundaries to offset carbon and how far the emission has exceeded beyond them, this paper aims to calculate the carbon carrying capacity and evaluate its availability to sequester CO2 emission in a certain area. Considering forests, the major carbon reservoir to be the key ecosystem and taking West Sumatera Province in Indonesia as the case study, the Carbon Carrying Capacity (CCC) assessment is conducted with ecological footprint concept through carbon capacity surplus-deficit. The results show the forest CCC was fluctuated which were the highest 3.9 million ton in 2016 and the lowest 2.4 million ton in 2019, and primary mangrove land cover was the biggest carbon sequesters for 114 ton C/ha every year. The forest CCC was dominantly deficit which interpreted as limited and unavailable forest capacity to offset carbon emission. To improve forest CCC, forest area needs to be conserved, also develop low-carbon and green economic transformation to reduce GHG emission. The local society can take role to conserve the forest through customary laws application, then the government ought to plan spatial strategies through limiting land use for the primary forest and prohibiting mangrove and swamp forest conversion, also monitor, control and make legal approach to achieve national targets on reducing CO2 emission.

Air limbah proses pengolahan gula yang dikumpulkan berasal dari pabrik gula X dari di Selangor. Inokulum mikroba diperoleh dari mikroflora yang terdapat dalam lumpur sedimentasi pada instalasi pengolahan air limbah. Proses pengolahan dilakukan dalam kondisi gelap, dengan parameter operasi utama meliputi pH, ukuran inokulum, dan suhu temperatur. Parameter yang diamati mencakup kebutuhan oksigen kimiawi (COD), total padatan tersuspensi (TSS), pH, dan produksi biogas. Inokulum diinkubasi selama dua hari menggunakan substrat berupa air limbah pengolahan gula, dengan pH disesuaikan menjadi 5,0 untuk menghambat aktivitas bakteri metanogenik. Pengolahan dilakukan dalam vial tertutup dengan volume kerja sebesar 10 mL. Studi pendahuluan menunjukkan bahwa waktu optimum pengolahan adalah 60 jam, berdasarkan efisiensi penurunan COD dan volume biogas yang dihasilkan. Dalam eksperimen utama, parameter operasi divariasikan, yaitu ukuran inokulum (10%, 20%, 30%) dan temperatur (30°C, 35°C, 40°C). Proses ini mampu menurunkan COD hingga 82%, serta mikroflora yang digunakan menunjukkan kemampuan menghasilkan biogas hingga 1,6 mL per 10 mL limbah. Penurunan pH selama proses pengolahan diamati sebagai akibat aktivitas bakteri penghasil asam (asidogenik). Selain itu, terjadi peningkatan signifikan pada TSS, dengan kenaikan maksimum mencapai 460%, yang mengindikasikan pertumbuhan mikroba dan akumulasi biomassa.
