Abstract

This study aims to design and manufacture an aerobic composter that is different from the existing composters and to test the aerobic composter by composting household organic waste. Household organic waste used in this research consisted of two different compositions. The first composter (A) consisted of 2 kg of vegetable-fruit skin scraps and 0.5 kg of rice residue, while in the second composter (B), there was an addition of 0.25 kg of eggshell flour. Composting was done for 28 days. EM4 was used as an activator in the amount of 15 ml diluted with 500 ml of water and added with a starter of commercial organic compost as much as 20% of the total mass of raw materials. The results showed that (1) the aerobic composter that was designed and made in this study has three main parts, namely the upper part functions as a place for enumeration, the middle part functions as a place for composting, and the bottom part serves as a place for liquid fertilizer leachate so that the composter is more integrated and practical compared to existing composters, (2) aerobic composter can be used for the composting process of household organic waste. The compost produced meets Indonesian National Standard Number 19-7030-2004 for physical parameters, namely temperature (25°C), humidity (20%) and pH (6.8), and meets the Regulation of Minister of Agriculture of The Republic of Indonesia Number 70/Permentan/SR.140/10/2011 on the C/N-ratio parameter, which is 25 for compost A and 22 for compost B.   Abstrak Tujuan dari penelitian ini adalah merancang dan membuat alat pengomposan aerobik yang berbeda dari alat pengomposan yang sudah ada dan menguji alat pengomposan aerobik dengan cara mengomposkan sampah rumah tangga. Sampah organik rumah tangga yang digunakan pada penelitian ini terdiri atas dua komposisi  berbeda. Komposter pertama (A) terdiri atas 2 kg limbah sayur dan kulit buah serta 0,5 kg limbah nasi, sedangkan pada komposter kedua (B) ditambahkan tepung cangkang telur sebanyak 0,25 kg. Pengomposan dilakukan selama 28 hari. EM4 15 ml digunakan sebagai aktivator, diencerkan dengan 500 ml air, dan ditambahkan starter kompos organik yang tersedia secara komersial sebesar 20% dari total massa bahan baku. Hasil penelitian menunjukkan bahwa: (1) komposter aerobik yang telah dirancang dan dibuat pada penelitian ini memiliki tiga bagian utama, yaitu bagian atas berfungsi sebagai tempat pencacahan, bagian tengah berfungsi sebagai tempat pengomposan, dan bagian bawah sebagai tempat menampung lindi pupuk cair sehingga komposter ini lebih terpadu dan praktis dibandingkan dengan komposter yang telah ada saat ini, (2) komposter aerobik dapat digunakan untuk proses pengomposan sampah organik rumah tangga.

Abstract

This study investigates the use of nanocellulose and polyvinyl alcohol (PVA) suspension as a coating formulation on a paper substrate and its effects on the paper’s oil and water barrier properties. The PVA/nanocellulose coating suspension was prepared via a simple nanocellulose mixing procedure with various concentrations of PVA. The coating was carried out by depositing an adhesive agent and multiple layers of nanocellulose/PVA suspension on the paper surface using a bar coater. The results showed that coating up to the fourth layer decreased the opacity index and air permeability rate of the coated papers, but there was a slight increase in the air permeability at the sixth layer. The deposition of PVA/nanocellulose suspension on the paper surface also increased the water and oil barrier performance. The highest contact angle (CA) of 82° and oil kit value of 14 was obtained at the fourth layer of coating using suspension with 2 wt% of PVA content, as compared to the uncoated paper (CA 43°). It is interesting to note that coating paper using nanocellulose/PVA suspension can effectively enhance the hydrophobicity and oil barrier performances of the paper. This satisfactory results in paper properties after being coated with nanocellulose/PVA suspension can be a potential environmentally friendly material in food packaging applications.

Abstract

The batik industry in Pekalongan benefits the economy but harms the environment when untreated batik waste is discharged into rivers. The fungus Aspergillus sp. can degrade batik wastewater as an absorbent using its mycelium. Immobilizing mycelium with substrates such as loofah or oyong (Luffa cylindrical) is a practical method for waste degradation. These substrates offer unique tubular fiber structures, affordability, easy availability, environmental friendliness, high stability, and rapid adsorption ability. This study aimed to determine the decolorization of Pekalongan batik dye wastewater using Aspergillus sp. immobilized on Luffa at different incubation times and types of inoculums. This research will provide scientific information about the ability of Aspergillus sp. immobilized on Luffa to batik waste, particularly in the Pekalongan batik industry. The initial research used a dry immobilization model to study the spore and mycelium inoculum. The spore inoculum type was found to decolorize batik wastewater by 75%, which was better than the mycelium inoculum type, which achieved 37.5% decolorization. The research showed that Aspergillus sp. immobilized on Luffa without a drying process could decolorize Pekalongan batik wastewater. The most optimal decolorization results were obtained with spore inoculum treatment at an incubation time of 72 hours, achieving 99.7% decolorization. This research is supported by measurements of the dry weight of Aspergillus sp. immobilized on Luffa, pH value, DO content, TSS content, TDS content, and temperature, with respective values of 2.294-4.416 g; 5-7.14; 12-16 mg/l; 70-148 mg/l; 2013.2-3761 mg/l; and 29-31ºC.   Abstrak Industri batik di Pekalongan menguntungkan secara ekonomi bagi masyarakat, namun berdampak negatif bagi lingkungan ketika limbah batik tidak diolah dan langsung dibuang ke sungai, sehingga menyebabkan polusi. Jamur Aspergillus sp. dapat digunakan untuk mendegradasi air limbah batik karena menghasilkan enzim, dan secara non enzimatis sebagai penyerap dengan menggunakan miselium. Mengimobilisasi miselium dengan substrat, seperti buah gambas atau oyong (Luffa cylindrical), dapat menjadi metode praktis untuk degradasi limbah. Substrat ini memiliki keunggulan seperti struktur serat berbentuk tabung yang unik, harga yang terjangkau, mudah didapat, ramah lingkungan, stabilitas yang tinggi, dan kemampuan adsorpsi yang cepat. Tujuan penelitian ini adalah untuk mengetahui dekolorisasi air limbah pewarna batik Pekalongan menggunakan Aspergillus sp. yang terimobilisasi pada Luffa pada waktu inkubasi dan jenis inokulum yang berbeda. Manfaat penelitian ini untuk memberikan informasi ilmiah mengenai kemampuan jamur Aspergillus sp. terimobilisasi Luffa dalam mendekolorisasi limbah batik, khususnya industri batik di Pekalongan. Pada penelitian awal, jenis inokulum spora dan miselium dikaji dengan menggunakan model imobilisasi kering. Jenis inokulum spora ditemukan dapat mendekolorisasi air limbah batik sebesar 75%, yang lebih baik daripada jenis inokulum miselium yang mencapai 37,5% dekolorisasi. Hasil penelitian berupa perlakuan Aspergillus sp. terimobilisasi Luffa tanpa proses pengeringan yang diujicobakan dapat mendekolorisasi air limbah batik Pekalongan. Hasil dekolorisasi yang paling optimal diperoleh pada perlakuan inokulum spora dengan waktu inkubasi 72 jam, yaitu sebesar 99,7%. Penelitian ini didukung oleh pengukuran berat kering Aspergillus sp.3 terimobilisasi Luffa, nilai pH, kadar DO, kadar TSS, kadar TDS, dan nilai temperatur berturut-turut sebesar 2,294-4,416 g; 5-7,14; 12-16 mg/l; 70-148 mg/l; 2013,2-3761mg/l; dan 29-31ºC.

Abstract

Establishing a waste bank in Surakarta City is not only intended to manage household waste The waste bank can also serve to improve the community's economy. Since 2014, the Surakarta City Environmental Services (DLH) has been promoting the formation of waste banks. There were 123 waste banks recorded in Surakarta City until 2020; in 2021, only 70 remained. Furthermore, not all waste banks can run well. Therefore, this study examines how to develop waste bank management to improve household income in Surakarta City. This study used a descriptive method and Miles and Huberman analysis using 120 waste bank customers and 13 managers as respondents. The result showed that the waste bank contribution to the household income was IDR 26,461/month, which means that some aspects need improvements, such as human capacity, infrastructure and facilities, time management, economic incentives, and the program itself. This study provides recommendations on how to maintain and increase waste bank activities to enhance household welfare and environmental quality.

Abstract

The coastal area of West Kalimantan has a wealth of marine and river fishery resources that have the potential to be utilized optimally, including fishing, conservation, port activities, marine cultivation, coastal tourism, and water. Various problems in coastal areas that need to be prioritized to provide solutions include the occurrence of illegal fishing, damage to coral reef ecosystems and mangroves, coastal abrasion, not yet optimal development of ponds where utilization only reaches 40% of their potential, natural disasters which result in increased poverty and ecosystem damage, as well as the growth of corruption and injustice. The number of people living in poverty has been steadily increasing at an average rate of 6.86% over the past three years, reaching 353,350 individuals in 2023. This research aims to develop coastal areas, creating local economic development innovations to reduce poverty, unemployment, and inequality and preserve natural resources. The method developed in this study was carried out descriptively and qualitatively by developing an in-depth analysis through SWOT. The results provide solutions for improvements and innovations, which include implementing a blue economy by utilizing the modernization of fishing gear, developing a paradigm shift from land to water resources, and producing garbage filters in rivers so they do not wash away into the sea. This study will improve the quality of life economically and socially while maintaining the ecology in coastal areas.

Abstract

Increasing concern about sustainability and environmental issues caused by the massive amount of solid biomass waste in Indonesia has driven efforts to develop new products for various endues applications in energy, environment, and health sectors. This study uses coconut husk as the cellulose source to fabricate magnetic cellulose (MC) via coprecipitation with iron chloride salts. Combining cellulose with magnetite nanoparticles aims to improve the removal rate of synthetic dye as the latter provides high catalytic activity in the Fenton degradation process to eliminate persistent pollutants. The paramagnetic characteristics that MC possesses also make them quickly recovered after use. The adsorption capacity is found at 252.2 mg/g (pH 7, temperature of 30°C, the dye initial concentration of 100 ppm, and the precursor mass ratio of 1:4.8:25) for Rhodamine-B. The dye mineralization in this condition also reaches 50%, indicating that this adsorbent can be used as an efficient material to adsorb and degrade dye from an aqueous solution. This magnetic adsorbent will be of immense potential application for removing organic contaminants, particularly synthetic dyes, due to its good performance, simple separation, and ability to perform both adsorption and degradation processes simultaneously.
