Abstract

Farmers’ skills in maintaining water pumps remain limited, although these skills are essential for sustaining agricultural production. This study is presented as a pilot study aimed at assessing the effectiveness of participatory training in improving the knowledge, skills, and attitudes of water pump mechanics. The study involved nine mechanics under the guidance of UPTD ALSINTAN Dinas Pertanian Kabupaten Bandung, each representing one of nine affiliated areas. Evaluation was conducted using pre-test and post-test instruments with 20 items on a five-point Likert scale, analyzed descriptively without inferential statistics. The initial findings indicated an increase in the overall mean score from 3.55 to 4.78, with the largest improvements observed in skills (+46.27%) and knowledge (+39,83%). These results suggest improvements in competence, although they remain exploratory. The main limitations of this study are the small sample size and reliance on self-reported measures. Further studies with larger samples and stronger designs are recommended.

Abstract

This research focuses on the design and development of a solar-powered egg incubator specifically for free-range chickens, incorporating an automated sliding rack mechanism. One of the main issues encountered by poultry farmers is the inconsistency of electricity supply and the uneven distribution of heat within conventional incubators, both of which contribute to low hatch rates. To address this, the study employed the Quality Function Deployment (QFD) methodology alongside the House of Quality (HOQ) framework to systematically convert user requirements into engineering specifications. Primary data were gathered through Focus Group Discussions (FGD) with poultry practitioners, followed by experimental evaluations concerning thermal distribution performance and the reliability of the solar-powered backup system. Findings demonstrate that the integration of the automated rack and solar panel system resulted in a full (100%) hatching rate, with a stable incubation temperature maintained within the optimal range of 37 to 40°C. Additionally, the solar energy system ensured uninterrupted operation for approximately 7 hours in the event of a power outage. This technological innovation offers a sustainable, eco-friendly solution that holds the potential to significantly boost the productivity of local poultry farming.

Abstract

Indoor air quality (IAQ) plays a crucial role in the health and comfort of building occupants, where pollutants like formaldehyde can cause serious health issues. To reduce formaldehyde levels, photocatalytic oxidation (PCO) technology using titanium dioxide (TiO2) substrates has been shown to be effective. This study aims to optimize the PCO system design using TiO2-coated stainless steel mesh substrates in a honeycomb monolith reactor configuration to enhance formaldehyde degradation efficiency. Three variations of stainless steel mesh layers (5, 10, and 15 layers) were tested to evaluate their impact on formaldehyde (HCHO) concentration reduction. The results indicated that increasing the number of mesh layers significantly improved the formaldehyde degradation efficiency. The highest efficiency, 96.06%, was observed with 15 layers, compared to 74.67% with 5 layers and 83.19% with 10 layers. The increase in mesh layers enlarged the surface area of the substrate, enhancing the reaction area and interaction between pollutants and the photocatalyst. This study suggests using more than 10 layers of stainless steel mesh in the PCO system design to achieve optimal performance in formaldehyde pollutant reduction. The findings are expected to contribute significantly to improving indoor air quality, particularly in areas exposed to pollutants such as cigarette smoke.

Abstract

Indoor air pollution, particularly from cigarette smoke, contains harmful Total Volatile Organic Compounds (TVOC) that poses significant health risks. This study aims to evaluate the effectiveness of a Photocatalytic Oxidation (PCO)-based air purification system utilizing a Titanium Dioxide (TiO2)-coated stainless steel mesh reactor and Ultraviolet Light Emitting Diode (UV-LED) sources at 365 nm and 390 nm wavelengths. The methodology involved synthesizing TiO2 sol and immobilizing it onto a stainless steel 304 mesh substrate via a dip-coating technique. Performance testing was conducted in a closed room (volume approx. 136 m³) where smoke from two cigarettes was introduced as the pollutant source. TVOC concentrations were monitored every 5 minutes at five distinct measurement points (center and corners) over a 2-hour period to assess spatial distribution and degradation performance. The results demonstrated that the PCO system with a 365 nm UV-LED reduced the average TVOC concentration from 0.78 ppm to 0.33 ppm, achieving a reduction rate of 57.69%. Meanwhile, the 390 nm UV-LED system decreased the concentration from 0.86 ppm to 0.32 ppm, corresponding to a 62.8% reduction. While the difference in UV-LED wavelength did not significantly alter the photocatalytic performance, light intensity and initial pollutant concentration were found to influence the degradation rate. Overall, the TiO2-coated stainless steel mesh reactor proved to be an effective solution for reducing indoor cigarette smoke pollutants.
