Abstract

ABSTRAKTujuan penelitian dengan mengkaji potensi air limbah industri tahu (whey) menjadi suatu produk yang bernilai ekonomi bagi masyarakat. Penelitian dilakukan dengan metode survey untuk mengidentifikasi produksi air limbah whey pada industri tahu dan dilanjutkan dengan eksperimen karakterisasi dan pengolahan air limbah whey dengan skala laboratorium. Air limbah whey diolah dengan menggunakan biodigester anaerob sarang lebah (Honeycomb Biodigester) dengan kapasitas 120 liter. Tahapan penelitian dengan melakukan pembuatan starter dari campuran kotoran sapi, air, dan air limbah whey (3:1:1) yang difermentasi selama 21 hari. Setelah starter memperlihatkan pertumbuhan mikroorganisme (MO) berada pada fase log, maka dilanjutkan dengan pengumpanan air limbah whey sebanyak satu liter setiap hari. Hasil yang diperoleh memperlihatkan bahwa air limbah whey mengandung protein 0,9482%, karbohidrat 0,4473% dan lemak 0,2186% yang merupakan substrat bagi MO. Pengolahan air limbah whey secara anaerob dengan menggunakan Honeycomb Biodigester menghasilkan biogas dengan nyala api merah biru (gas metana > 45%). Kemudian  slury Honeycomb Biodigester mengandung senyawa urea yang merupakan kandungan pupuk. Oleh karena itu, potensi pengolahan air limbah whey dapat menghasilkan energi terbarukan (biogas), pupuk organic cair dan padat dengan kandungan vitamin E dan  tiophospatoethyl aminohexylurea  (unsur N dan P) serta menjadi solusi dalam penaganan pencemaran lingkungan, sehingga tercipta industri yang berkelanjutan.  Kata kunci : Biogas, pupuk organic, sarang lebah, whey. ABSTRACTThe research aims to examine the potential of tofu industry wastewater (whey) to become a product of economic value for society. The research was carried out using a survey method to identify whey wastewater production in the tofu industry and continued with experiments on the characterization and processing of whey wastewater on a laboratory scale. Whey wastewater is processed using a honeycomb anaerobic biodigester with a capacity of 120 liters. The research stage involves making a starter from a mixture of cow dung, water, and whey wastewater (3:1:1) which is fermented for 21 days. After the starter shows that the growth of microorganisms (MO) is in the log, it is continued with one liter of whey wastewater every day. The results obtained show that whey wastewater contains protein 0,9482%,, carbohydrate0,4473%  and fat0,2186%  which is a substrate for MO. Anaerobic processing of whey wastewater using a honeycomb anaerobic biodigester produces biogas with a blue flame (methane gas > 45%). Then the Honeycomb biodigester slurry contains urea compounds which are fertilizer ingredients. Therefore, the potential for processing whey wastewater can produce renewable energy (biogas), liquid and solid organic fertilizer containing vitamin E and  thiophospatoethyl aminohexylurea (N and P elements) as well as being a solution for handling environmental pollution, thereby creating a sustainable.  Keywords: Biogas, organic fertilizer, Honeycomb, whey.

Abstract

Abstrak. Penelitian ini bertujuan untuk menentukan pengaruh model pelatihan SOLID (self confidence-opportunity- learning of technology-initiative–decision) terhadap pengetahuan dan keterampilan pelaku industri tahu pada pengolahan dan pemanfaatan limbah okara. Penelitian eksperimental ini merupakan bagian dari pengembangan model pemberdayaan masyarakat yang melibatkan 25 peserta untuk memanfaatkan okara menjadi pakan ternak dan pupuk kompos. Model pelatihan dilakukan pada bulan Mei-Agustus 2024. Aspek pengetahuan yang dinilai mengenai potensi okara, pengolahan okara, kandungan okara dan dampak lingkungan. Aspek keterampilan yang dinilai adalah kemampuan pada proses fermentasi okara, maggot sebagai agen pendegradasi, pakan ternak maggot, dan kompos berbahan okara. Berdasarkan analisis terdapat pengaruh penerapan model SOLID yang signifikan terhadap pengetahuan dan keterampilan bagi pelaku industri tahu dalam pengolahan dan pemanfataan okara menjadi produk pakan dan pupuk kompos. Hasil penelitian menunjukkan bahwa Model SOLID efektif meningkatkan pengetahuan sebesar 76 – 88 persen dan keterampilan sebesar 64 – 80 persen.  Kata Kunci : Industri tahu, okara, maggot, SOLID

Abstract

Many environmental problems currently faced globally are related to air pollution, primarly originating from biomass combustion on both small or large scales. Major contributors to particulate matter (PM2.5) and harmful organic substances such as CO can be found in the smoke from the combustion process. These particulates and toxic substances have been known to have adverse effects on human health. This study presents the design and development of a device called Clean Smoke, which has an efficiency rate of 78.65% in reducing harmful substances in air emissions and effectively trapping organic compounds from biomass. In addition, the test results showed that the residual waste liquid or liquid smoke produced by this tool showed a significant turbidity increase from 4.16 NTU to 25.5 NTU, indicating the ability of the tool and activated carbon to bind hazardous particulates in water. With further development, Clean Smoke device could significantly reduce exposure to emissions and toxic substances from combustion processes in small to large-scale industries, thereby contributing to a healthier environment and supporting the global goal of achieving zero-net emissions.

Abstract

Safflower, were extracted using propanol solvent at different time intervals: 10, 20, and 30 min at a constant temperature of 40°C. The extracts were analyzed by GC/MS technique. The major compounds identified were tetrapentacontane, tetracontane, triacontanol, gamma sitosterol, myristic acid, linoleic acid, stearic acid, palmitic acid, oleic acid, and lauric acid. However, some levels of palmidrol, beta-amyrin, cubenol, and tocopherol were also found in safflower extracts. Most of the volatile compounds were detected between 10–30 min time of extraction. The 30 min time of extraction also showed the maximum content of polyphenols and antioxidants in safflower extracts. Thus, 30 min was suggested as the most suitable time for maximum extraction of bioactive volatiles, antioxidants, and polyphenols from Safflower using propanol solvent.

Abstract

The purpose of this research is to determine the potential of solid and liquid waste produced from the tofu industry and do conduct management and processing studies by approach the clean production process applied to the tofu industry. Research methods were done through interviews and observations in the tofu industry in the urban village of Bara-Barayya. The results of the determination of the mass balance of the soybean washing and clumping with the each wastewater capacity range of 1,485 L and 1,262 L. The process of tofu production was totally producing solid waste of 420.65 kg per day and waste water ranged from 3,065.4 liters per day for production capacity of 150 kg of soybean or equivalent to 20.4 m3/ton daily. Predictions of waste water potential in the washing and clumping process in a month-on time was modeled using the Stella program. The quality standard of waste water for the soybean processing for the highest of 20 m3 per ton. Implementation of net production process were through the process of good house keeping, recycle, and on-site-reuse process.
