Abstract

Anaerobic digestion is to treat organic waste such as vegetable solid waste (VSW). Anaerobic co-digestion is the mixture of two or more different waste types with the aim to enhance the efficiency of the anaerobic digestion process. In this study, anaerobic digestion of vegetable solid waste (VSW) is compared to the anaerobic co-digestion of VSW and sequencing batch reactor (SBR) sludge. This investigation is focussed  on the varying the organic loading rate (OLR) which is the mixing ratio of VSW to SBR sludge; and pH (6, 7 and 8) of the mixture. The mixtures were kept in serum bottles and placed in a shaker for 7 days at 150 rpm. Experiments with OLR 2:1, VSW composition of 1:2:1:1 and pH 6 produced the highest total biogas in anaerobic co-digestion. Thus, for anaerobic co-digestion, the optimum composition of VSW, OLR and pH are 1:2:1:1, 2:1 and 6 respectively. The range of % reduction in total solids (TS), total suspended solids (TSS) and total dissolve solids (TDS) in anaerobic co-digestion is 4-46, 0-43 and 0-64 respectively. In a comparison with single digestion, only 1 in 5 samples of co-digestion exceed that amount of biogas produced by single digestion and this shows that single anaerobic digestion resulted in higher biogas yield. The range of % reduction in TS, TSS and TDS in anaerobic digestion is 13-54, 15-66 and 9-58 respectively. Comparatively, single digestion performs better in solids removal than anaerobic co-digestion and thus, co-digestion method may not be suitable for all types of organic waste.

Abstract

Batu Busuk has an excellent opportunity to become one of the tourist areas in the eastern region of Padang City. As a tourist area, the aspects of comfort and cleanliness in the area and surroundings are essential to provide a memorable travel experience, including the residential areas nearby. Lack of public awareness of waste management and waste treatment and no application of the 3R principles of reduce, reuse and recycle are the problems encountered in Batu Busuk. The community service implementation team carried out a series of activities from 2021-2022 to support sustainable tourism development. This activity aims to increase community understanding of waste and the importance of waste management and introduce and enhance the formation of a waste bank in Batu Busuk. The activities included counselling on waste management, comparative studies and field visits to Farmers Women Group Tunas Harapan and Panca Daya waste bank, which have implemented the treatment of organic and non-organic waste into various economically valuable products. It can be concluded that waste management in Batu Busuk is needed to support sustainable tourism. A Batu Busuk Waste Bank unit is required to effectively solve the waste management problem and reduce waste generation in Batu Busuk and its tourism area. Training on the method to treat both organic waste into plant nutrients and non-organic waste into various crafts must be conducted. The products have economic value and are an effective solution for reducing the volume of waste.

Abstract

The growth of illegal shrimp ponds in Batang Anai, Padang Pariaman Regency has been very widespread recently. This is because the advantages of shrimp cultivation include fast growth, high survival rate, high shrimp appetite, greater resistance to disease attacks and relatively short rearing time, namely 90-100 days per cycle. As shrimp cultivation develops in this area, environmental pollution problems arise. Of course, this is contrary to Law number 36 of 2009 concerning Health, Article 4 and Article 6 states that everyone has the right to health and everyone has the right to a healthy environment for achieving a level of health. Based on preliminary interviews with the community around the shrimp ponds, it was stated that the existence of illegal shrimp ponds does not take into account the impact on the environment, and even disturbs the community. Meanwhile, there is no action by the district or local government to control or manage the impacts, so various efforts are needed to restore optimal health status for the surrounding community.

Abstract

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. Kata Kunci: air limbah pabrik gula, microflora, pengolahan anaerobik, penyisihan COD, ukuran inoculum,

Abstract

Penelitian ini bertujuan untuk mengevaluasi potensi filter biochar susunan seri dalam menyisihkan detergen dan fosfat dari air limbah artifisial. Filter yang digunakan terdiri atas media biochar dan busa poliuretan dengan perbandingan volume 2:1, disusun dalam dua kolom seri masing-masing setebal 40 cm. Proses filtrasi berlangsung selama 14 hari, dengan konsentrasi awal detergen sebesar 0,701 mg/L dan fosfat sebesar 1,303 mg/L. Hasil penelitian menunjukkan bahwa konsentrasi detergen pada efluen kolom seri 1 dan 2 masing-masing berkisar 0,21-0,43 mg/L dan 0,19–0,33 mg/L, dengan efisiensi penyisihan 39–70% dan 53–72%. Sementara itu, konsentrasi fosfat pada efluen kolom seri 1 berkisar 0,33–0,84 mg/L dengan efisiensi 35–74%, dan pada kolom seri 2 sebesar 0,14–0,66 mg/L dengan efisiensi 49–89%. Penyisihan yang lebih tinggi setelah melewati kolom seri 2 menunjukkan bahwa waktu retensi aliran berperan penting dalam meningkatkan efisiensi penyisihan kontaminan. Secara keseluruhan, penelitian ini menegaskan bahwa filter berbasis biochar berpotensi sebagai media ramah lingkungan untuk pengolahan air limbah yang mengandung detergen dan fosfat.
