Abstract

Natural fibers are increasingly utilized as reinforcing materials in the modern materials industry. In this study, composites comprising 15% untreated coconut fiber, pineapple leaf fiber, palm fiber, corn husk fiber, or sugar cane fiber and 85% polyester were fabricated. Water absorption was evaluated by immersing the composites for 3, 7, 14, and 21 days. The tensile strength and morphology of unsoaked composites were also assessed to determine the influence of fiber type. Water absorption increased with immersion time for all composites, although the trends varied among fiber types. The coconut fiber composite exhibited the highest water absorption rate, whereas the pineapple leaf fiber composite demonstrated the lowest. The pineapple leaf fiber composite also achieved the highest tensile strength. In contrast, composites containing coconut fiber, palm fiber, corn husk fiber, and sugar cane fiber displayed lower tensile strength, attributed to imperfect interfacial bonding between the fibers and the polyester matrix.

Abstract

This study aims to improve the energy efficiency of a 100 kg/h fire-tube mini boiler through combustion chamber redesign and analysis of air intake variations. The redesign was conducted using SolidWorks software with thermal insulation made of bricks, cement, sand, and refractory cement to reduce heat loss. Experiments were carried out by varying blower air velocity from 3 to 17 m/s, measuring combustion chamber temperature, steam temperature, water temperature, pressure, fuel consumption, and energy efficiency. The results show that an air velocity of 11 m/s achieved the best performance, with a maximum efficiency of 86% at 1 bar pressure. Efficiency decreased at lower air velocity due to limited oxygen supply and at higher velocity due to excessive air absorbing heat energy. The redesigned combustion chamber produced more stable combustion, reduced fuel consumption, and improved continuous steam production

Abstract

This study aims to analyze the effect of biodiesel blend variations on the performance and exhaust emission characteristics of a diesel engine equipped with a Common-Rail Direct Injection (CRDI) system. The experimental tests were conducted using two types of fuel, namely B50 (50% biodiesel and 50% diesel) and B100 (pure biodiesel). The evaluated parameters included fuel consumption (FC), specific fuel consumption (SFC), and exhaust emissions consisting of CO, CO₂, NO, NOₓ, O₂, and SO₂. Tests were performed at three engine speeds (800, 1000, and 1500 rpm) and three electrical load levels (600 W, 1000 W, and 2000 W). The results showed that both FC and SFC increased with higher engine speed and load, where the average SFC of B100 was 5–15% higher than that of B50 due to the lower calorific value of biodiesel. In terms of emissions, the use of B100 reduced CO concentration by up to 10% compared to B50, while NOₓ emissions increased by approximately 15–25% at higher speeds. SO₂ emissions were recorded at 0 ppm under all test conditions, indicating that biodiesel is sulfur-free. These findings confirm that pure biodiesel can be effectively utilized in modern diesel engines with common-rail injection systems, providing good combustion efficiency and contributing to the reduction of exhaust gas emissions.

Abstract

The fish smoking industry in Wonosari Village, Demak Regency, produces around 20-25 tons daily, relying on traditional methods that often result in inconsistent quality and compromised hygiene. This study seeks to boost efficiency and product quality by introducing semi-automatic smoking technology powered by technopreneurship principles. The technology integrates conveyor systems and rapid cooling to streamline the smoking process. Using an experimental approach with a technopreneurship twist, the research team collected data through observations, interviews, and prototype testing at Sentra Asap Indah. The testing focused on temperature control, smoking duration, and product quality analysis, including texture, aroma, and food safety. The prototype demonstrated significant efficiency gains, cutting smoking time by 30% and standardizing the process. The rapid cooling system successfully brought the fish temperature down from 80°C to 30°C within 30 minutes, a crucial step in preventing bacterial growth and preserving texture. The overall quality of the smoked fish, in terms of color, taste, and aroma, showed consistent improvement. By integrating conveyor systems for process standardization and rapid cooling for enhanced food safety, this technopreneurship initiative has the potential to increase the competitiveness of local smoked fish products and drive business sustainability.
