Abstract

Limited subsidized fertilizer has caused the Tirtobakti II Farmers Group to provide organic fertilizer independently. Even though the process of making organic fertilizer using fermentation is well known, the process of making organic kasgot fertilizer is the choice of KT Tirtobakti II because it is more practical and efficient. KT Tirtobakti II's kasgot production process is constrained by limited maggot production resources and limited maggot production facilities. Empowerment activities at KT Tirtobakti II aim to develop the capabilities of KT Tirtobakti II members in increasing kasgot production capacity by providing maggot feed and production facilities. Activities are carried out through a series of activities in the form of education, practice, mentoring, and evaluation. The positive impact of empowerment activities can be seen in the increasing ability of KT Tirtobakti II members to calculate the need for maggot feed ingredients according to kasgot production targets, the existence of partnership cooperation between KT Tirtobakti II and fruit and vegetable traders in traditional markets to meet maggot feed needs, and increasing production capacity by using maggot house facilities.

Abstract

Hydrogen is the promising ideal energy carrier with no emission but water on its combustible in the next generation. Hydrogen production using biological methods is greener than other methods using fossil fuel. One of the major factors affecting the operation of biohydrogen production is pH level in bioreactors. Restrain of declining pH is expected to increase hydrogen production. Pretreatment is one key factor in successful biohydrogen fermentation using mixed microbes. This study aims to investigate the natural buffer effect on biohydrogen using hot compressed water pretreatment. This batch fermentation experiment was operated in a 110 mL glass reactor with 3.75 g/L glucose as substrate. Mixed culture was obtained from cow dung compost treated with hot compressed water pretreatment at 150 ºC, 0.5 MPa for 40 minutes. Fine dried eggshell powder and calcinated eggshell were added with 1 g/L, 3 g/L, and 5 g/L concentrations as buffer agents. The result showed that the addition of 1 g/L eggshell obtained the highest hydrogen production rate of 0.92 mol H2/mol glucose. Butyric acid and acetic acid are recognized as an indicator of hydrogen production and the Butyric/Acetic molar ratio over 2.6 as efficient biohydrogen fermentation. The highest B/A ratio in this experiment was 4.62 on 3g/L addition of eggshell powder.

Abstract

The rapid expansion of agro-industrial activities in Indonesia has led to a significant increase in exhaust gas emissions, including formaldehyde (HCHO), volatile organic compounds (VOCs), carbon dioxide (CO₂), and carbon monoxide (CO). These pollutants contribute to the formation of tropospheric ozone, acid rain, and greenhouse effects, which directly impact human health and ecosystems. Although wet scrubber technology is widely used to reduce such pollutants, conventional systems remain limited, particularly in capturing non-polar gases and micro-particles. This study developed a biomaterial-based wet scrubber system that integrates a mechanical approach (nozzle diameter variation) with a material approach (banana-stem biomaterial filter) to improve pollutant gas absorption efficiency. Four nozzle diameters (0.8, 0.5, 0.3, and 0.1 mm) and three biomaterial filter densities (50, 75, and 100 g/L) were tested for their performance in absorbing HCHO, VOCs, CO₂, and CO gases. The results demonstrated that the combination of a 0.3 mm nozzle and a 100 g/L banana-stem filter achieved the highest absorption efficiencies 87.5% for VOCs, 84.2% for HCHO, and 90.1% for CO₂. The decrease in water pH from 7.1 to 5.8 indicated enhanced dissolution of acidic gases, while the increase in TDS up to 1.350 mg/L reflected the accumulation of dissolved compounds due to absorption reactions. ANOVA analysis confirmed that both nozzle diameter and filter density significantly affected system efficiency (p < 0.05). This study highlights the potential of integrating biomaterial-based wet scrubber technology as an effective, economical, and sustainable solution for industrial air pollution control, supporting the transition toward green industrial practices in Indonesia.

Abstract

Indonesia’s agroindustrial sector has experienced rapid growth in response to increasing demand for processed agricultural products; however, this development has also introduced environmental challenges in the form of air pollution from biomass combustion, such as sugarcane bagasse, tree branches, and organic waste. These combustion processes generate hazardous pollutants, including HCHO, TVOC, PM2.5, PM10, CO, and CO₂. This study aimed to develop and evaluate a wet scrubber system to reduce these emissions using three treatment methods: a water sprayer, a water trap, and a combination of both. Experiments were conducted using a mixture of sugarcane bagasse and organic waste with a combustion duration of 10 minutes and three replications for each treatment. Measured parameters included HCHO, TVOC, PM2.5, PM10, CO, CO₂, as well as water quality indicators (pH and TDS). Data were analyzed using ANOVA followed by Tukey’s HSD test. The results demonstrated significant reductions in HCHO (98.02%), TVOC (96.70%), CO (98.52%), and CO₂ (87.77%), with the combined method showing the best overall performance, although the effectiveness in reducing PM2.5 and PM10 remained limited. Overall, wet scrubber technology offers a practical and environmentally friendly solution for emission control in agroindustrial activities and supports the implementation of sustainable industrial practices.

Abstract

This study evaluates the drying efficiency of tobacco (Nicotiana tabacum L.) using the traditional hanging (jantur) method combined with calcium carbide (CaC₂) as an acetylene-generating accelerator. Motivated by common challenges in smallholder postharvest handling—long drying times, weather dependence, and uneven quality—we conducted an experimental trial comparing three treatments: control jantur without CaC₂, jantur with 100 g CaC₂ per chamber, and jantur with 200 g CaC₂ per chamber. Each treatment used randomized placement of 100 sticks, and monitoring included periodic moisture measurements, temperature and relative humidity logging, organoleptic grading, and economic cost analysis. Data collection occurred three times daily to capture drying dynamics and to construct drying curves for each treatment. Results show that all jantur treatments reduced drying time relative to conventional sun drying, achieving final moisture contents near industry targets within approximately 12 days. Average drying rates were close across treatments (≈5.65–5.79% per day), and ANOVA produced non-significant differences (F = 0.3009, p = 0.7421). However, grading outcomes favored the 200 g CaC₂ treatment, which yielded the highest proportion of Grade B leaves (90%) and no Grade C, while 100 g produced mixed results with reduced Grade D but higher Grade C share. Economic assessment indicates substantial cost savings per cycle for jantur treatments compared to sun drying, even after allocating greenhouse investment and CaC₂ costs. In conclusion, integrating CaC₂ into jantur drying offers practical benefits for smallholders by shortening drying cycles and improving grading consistency at modest additional input cost. Although statistical differences in drying rate were not significant, quality and economic indicators support trial adoption, particularly at the 200 g dosage. We recommend larger-scale trials, residue analysis, and safety assessments to validate these findings and ensure safe field application. Further outreach and farmer training on safe CaC₂ handling and ventilation practices should accompany extension of this technique to communities.

Abstract

Research was conducted to discover the ideal microwave blanching parameters for producing high-quality tomatoes. The experiment employed response surface methodology (RSM) with Box Behnken Design (BBD) and consisted of 17 treatments; each treatment combination was tested in duplicate. The independent variables were power (W) (X1), time (sec) (X2), and blanching water (mL) (X3). The experimental results were analyzed using ANOVA, and the optimization process was carried out and verified. The best treatment outcomes were obtained using a combination of 200 W power, 120 sec duration, and 450 mL of blanching water. After validation, the optimal yield response was 100.01%, with total soluble solids at 3.6 ºBrix, vitamin C at 154 mg/100 g, and total tomato carotene at 3.3 mg/100 g. Overall, these data have a 95% confidence interval ranging from low to high.Keywords: blanching, microwave-assisted, optimization, response surface methodology, tomatoes
