Abstract

Laundry atau yang dikenal dengan jasa cuci pakaian saat ini merupakan suatu aktifitas yang tumbuh pesat di tengah masyarakat modern. Perilaku dari aktifitas ini menghasilkan limbah buangan yang sangat beragam ke lingkungan. Salah satunya adalah Fosfat (P) yang dihasilkan oleh detergen dan hasil reaksi antara zat additif yang ada pada pakaian dan detergen pencuci. Untuk melakukan pengendalian kepada limbah buangan laundry tersebut, maka diperlukan suatu proses penyerapan atau adsorbsi terhadap Fosfat (P) yang dapat mencemari lingkungan. Secara umum adosrben yang ada di pasaran dan cukup dikenal adalah Silika Oksida (SiO2) dan Karbon Aktif ( C ). Tujuan dari penelitian ini adalah untuk mencari angka optimalisasi rasio penggunaan adsorben silika oksida dan/atau karbon aktif dalam proses penyerapan Fosfat (P) dalam limbah buangan laundry. Perlakukan yang dilakukan pada penelitian ini adalah dengan memvariasikan berat adsorben yaitu 50 gram silika oksida, 15 gram silika oksida dan 35 gram karbon aktif, 25 gram silika oksida dan 25 gram karbon aktif, 35 gram silika oksida 15 gram karbon aktif dan 50 gram karbon aktif kedalam limbah sebanyak 250 ml larutan limbah dan diaduk didalam erlenmeyer selama 150 menit. Dari hasil penelitian ini ditemukan bahwa penggunaan karbon aktif tunggal sebagai adsorben memberikan daya adsorbsi yang lebih besar dari pada seluruh variasi perlakuan yang dilakukan. Untuk penggunaan karbon aktif jumlah Fosfat (P) terserap sebanyak 61,18%. Sedangkan untuk penambahan silika oksida lebih dari 70% menyebabkan penurunan daya adsorbsi yang semakin besar. Tercatat untuk penggunaan adsorben 35 gram silika oksida dan 15 gram karbon aktif, Fosfat (P) yang terserap hanya sebesar 6,86%.

Abstract

Tofu also has a weakness, namely its high water content, so it is easily damaged because it is easily overgrown by microbes. Preservatives added are not limited to preservatives that are allowed, but many businessmen are naughty by adding formalin. White tofu is one that is circulating in the market. At room temperature the yower storage knows an average of 1-2 days. Efforts to preserve tofu by means of steaming and storing in a refrigerator can only preserve tofu for 1 day. This causes traders to commit fraud, one of which is preserving tofu so that it is durable, one of which is the addition of chemicals. According to the Food and Drug Supervisory Agency (BPOM). The treatment research method with the application of chitosan as an edible coating on white tofu is carried out in four stages, namely the preparation stage, immersion stage, storage stage, and testing stage. The preparation stage is carried nut by preparing all the materials and tools that will be used in the immersion, storage and testing stages. The immersion stage was done by soaking white tofu with concentrations varying of 0.5%  The results of the long storage test for tofu coated with chitosan showed that the tofu soaked with chitosan solution with the addition 0.01 %.

Abstract

Research has been carried out on the utilization of biomass waste of coconut trunk sawdust using the pyrolysis method to produce two products simultaneously, namely charcoal and liquid smoke. In order to obtain charcoal products with optimum calorific value, it is necessary to understand the optimum pyrolysis conditions. One of the optimum conditions, namely pyrolysis temperature, was studied in this research. Pyrolysis was carried out in a simultaneous pyrolysis reactor at a flow rate of argon inert gas into the reactor of 2 liters/minute and a pyrolysis time of 2.5 hours with pyrolysis temperature variations of 350, 400, 450, and 500°C, respectively. The study showed that the optimum temperature of 400oC was obtained which gave a yield of 34% charcoal with a calorific value of 7229 kcal/kg. Compared to the calorific value of the raw material for coconut sawdust which is 4400 kcal/kg, there was an increase in the calorific value of the pyrolysis product by 64%. Based on the optimum temperature condition, liquid smoke as a by-product was also obtained with a yield of 45%. Charcoal can be used as a solid fuel or as a bioadsorbent in the treatment of liquid waste or clarification of liquid food products such as virgin coconut oil (VCO). Grade 3 liquid smoke can be used as a biopesticide, while grade 1 liquid smoke can be used as a food preservative. Given the benefits of the two pyrolysis products, both of the products from the current research have a promising market value.

Abstract

Liquid smoke is a product resulting from the pyrolysis of biomass waste that contains chemical compounds with various applications, such as food preservatives, natural pesticides, and raw materials for the chemical industry. Liquid smoke is a by-product of simultaneous pyrolysis. To maximize the yield of liquid smoke while minimizing mass loss that could potentially pollute the environment, the simultaneous pyrolysisreactor needs to operate under optimal condensation conditions. This study observed two condensation parameters: the flow rate and the cooling water temperature of the condenser, using the case study of pyrolysis of biomass waste from coconut trunk sawdust. Pyrolysis was conducted at a temperature of 400°C for 2.5 hours, varying the flow rate of the cooling water in the condenser (1, 2, 2.5, 3, and 3.5 liters/minute)and the temperature of the cooling water (10°C, 20°C, 25°C, and 30°C). A multivariable nonlinear mathematical model was obtained, relating the yield of liquid smoke (y; %) to the water temperature parameter (x1) and the flow rate of the cooling water in the condenser (x2), which is expressed as y = 6.68 + 1.89x1 – 0.04x1² – 0.41x1x2 + 13.06x2 – 0.89x2². It was concluded that the optimal condensation conditions consist of a flow rate and cooling water temperature of 2 liters/minute and 20°C, respectively, yielding a maximum of 36% liquid smoke, 33% charcoal, and a minimum mass loss of 31%. Based on the coefficient values in the obtained mathematical model, it can also be concluded that the more dominant parameter affecting the yield of liquid smoke is the flow rate of the cooling water in the condenser, with a coefficient value of 13.06. An effective condensation system can enhance the conversion efficiency of pyrolysis vapour into liquid smoke and minimize potential pollution, demonstrating significant potential in processing biomass waste into valuable products, such as liquid smoke and charcoal, while being more environmentally friendly and energy-efficient.

Abstract

This study examined the effectiveness of utilizing household wastewater as asubstrate for biogas production through anaerobic fermentation at ahousehold scale in Tobarakka Village, Pitumpanua District. The objectives ofthe study were to assess the ability of various types of wastewater (ricewashing, vegetable waste, and a mixture) to produce biogas and to modeltheir production kinetics. Samples were processed in a simple biodigester(household-scale plastic bottles) and gas production was measuredperiodically using the air displacement method; data were analyzed statistically (ANOVA / LMM) and modeled with the Modified Gompertzequation. The results showed that biogas production per interval decreasedover time but the 40-day accumulation was highest in the mixture treatment(450 mL), followed by rice washing (355 mL) and vegetable waste (135 mL).Changes in pH and mesophilic conditions (≈30–35 °C) were noted to supportmethanogenic activity even though the final pH was close to the loweroptimal limit. The ANOVA/LMM test indicated that the effect of time washighly significant (p < 0.001), the effect of treatment was approaching significance (p ≈ 0.050), and the Treatment×Time interaction was significant(p = 0.028), suggesting different production patterns between substrates overtime.Modified Gompertz modeling confirmed the mixture as the substrate withthe highest cumulative potential and production rate. Limitations include thesmall number of replicates (n = 3) and the lack of gas composition analysis(%CH₄, %CO₂, H₂S) and VFA/COD parameters; therefore, additionalreplicates, gas composition measurements, and mixing ratio optimization arerecommended for further research. Practically, the utilization of household liquid waste, especially in combination, has the potential to be a householdscalerenewableenergysolutionwhilereducingenvironmentalpollution.
