Abstract

The milling station is a station where sugar cane-based sugar is produced, readiness is needed especially from the point of view of equipment maintenance in order to support the production process. Total Productive Maintenance (TPM) is one method of maintenance approach with Overall Equipment Effectiveness (OEE) is one of the measuring tools in calculating the effectiveness of equipment. Failure Mode and Effect Analysis (FMEA) is one method in analyzing the cause and effect of each device so that later it is hoped that this research can determine the value of the effectiveness of the equipment and provide recommendations for improvements. The calculation of the effectiveness of the equipment at the milling station that the effectiveness values ​​from 2013 to 2017 are 75.87%, 84.17%, 87.58%, 61.53% and 92.59%. In 2013, 2014 and 2016 showed that the value of effectiveness is still below the standards of world class effectiveness values. Factors that influence the effectiveness of 2013 to 2017 are Reduce Speed ​​Losses and Set-up adjustments time. Improvement of recommendations according to the TPM pillar in increasing productivity is 5S (Seiri, Seiso, Seiton, Seiketsu, and Setsuke). Keyword: Total Productive Maintenance (TPM), Overall Equipment Effectiveness (OEE), Failure Mode and Effect Analysis (FMEA).

Abstract

The production of syngas from coffee husk biomass waste as a raw material offers significant potential as an alternative automotive fuel source through the gasification process, considering the abundant resources available. Therefore, this study aimed to characterize the physical properties of the fuel initially, in order to observe the differences in these properties after the fuel underwent Ultra Fine Bubble treatment. The objective was to analyze the combustion characteristics of syngas derived from coffee husk biomass waste, to develop a sustainable alternative to fossil fuels for automotive applications. The results showed that with increasing air discharge, the concentration of CO and H₂ gases in gasified syngas increased while the concentration of CH4 decreased. Additionally, higher air discharge resulted in lower tar content, higher flame temperature, higher flame height visualization, and higher generator power output as a review of the feasibility of alternative automotive fuels.

Abstract

Biomass gasification is a promising renewable energy technology for the production of synthetic gas (syngas), consisting of hydrogen (H₂), carbon monoxide (CO), and methane (CH₄). This technology's primary challenge is tar formation – a heavy hydrocarbon compound that can block equipment, poison catalysts, and deteriorate syngas quality. Therefore, this study aimed to examine different tar reduction methods to support clean energy production through biomass gasification. To achieve this aim, two main approaches were adopted and the first was in-situ, focusing on modifying gasifier design and adjusting operational parameters. The second was ex-situ, which included catalytic reforming, thermal cracking, and plasma technology. The analysis also assessed different catalysts, such as biochar, and dolomite, as well as nickel- and iron-based materials, comparing their efficiency, sustainability, and economic viability. Several key factors influenced tar formation and reduction, namely feedstock type, operating temperature, air ratio, and reactor configuration. The result showed that combining in-situ and ex-situ technologies had substantial potential to significantly reduce tar, improve syngas quality, and optimize system performance. However, some challenges observed were reduced catalyst efficiency, high energy costs, and the need for more sustainable technologies. To improve the performance of gasification systems, this study provided information on catalyst development, operational parameter optimization, and plasma technology integration. Finally, the analysis provided a scientific basis and strategic recommendations to overcome tar problems and encourage the commercial use of biomass gasification towards a clean energy transition.

Abstract

Indonesia's natural resources, such as coffee hulls in Jember Regency, are potential sources of biomass raw materials that can be processed into biomass energy. Gasification is the process of converting solid fuels into combustible gases (CO, CH4, H2) through a heating process with minimal air conditions. This research focuses on the effect of air flow rate on the syngas productivity of coffee husk biomass gasification. It was found that higher air flow rate produces higher syngas content. The highest syngas composition with the highest LHV value was obtained by the 40 SCFH air flow rate variation with an LHV value of 141.7 kJ/mol.

Abstract

The purpose of this study was to determine the effect of eggshell catalyst (CaO) on the combustion characteristics of nyamplung oil biodiesel droplets (Calophyllum inophyllum L) on flame visualization, ignition delay, and temperature. At present, Indonesia still uses fossil fuels, namely diesel. However, over time there are alternative fuels using palm oil raw materials. However, palm oil is also used as a source of food so that it will have an impact on the scarcity of palm oil. In this study, we looked for alternative energy using nyamplung seeds (Calophyllum inophyllum L.) with catalyst weight variations of 1%, 3% and 5%. The tested droplet volume of 1 ml was placed in a type K thermocouple. The results of this study showed that the percentage of catalyst weight increased temperature and shortened ignition delay. The highest temperature and lowest ignition delay were found at a variation of 5% with the highest temperature of 679.5 °C and ignition delay of 3000 ms.

Abstract

This study examined how surface roughness and nanoceramic coating, influences the boiling heat transfer coefficient (BHTC) and critical heat flux (CHF) of a conical cylindrical copper test specimen. Three test specimens exhibiting surface roughness of 0.22 µm, 0.14 µm, and 0.04 µm were analyzed for comparison. Two additional test specimens were treated with nanoceramic coatings utilizing silicon carbide as the base material: one specimen received a single-layer coating and the second was applied with a double-layer coating. The behavior of the bubbles was closely observed with a high-speed camera to deepen the analysis. The experimental results showed that the test specimen with higher surface roughness exhibited higher BHTC and CHF. The 0.22 µm surface roughness specimen demonstrated a 55.69% greater BHTC than the 0.04 µm surface roughness specimen. In contrast, the 0.04 µm surface roughness specimen had the lowest CHF, 426.09 kW/m². Nanoceramic coating also enhanced the BHTC and CHF. The specimen with a single-layer coating had the highest BHTC, 40.81% higher than the uncoated specimen. The specimen with a double-layer coating showed a 60.12% increase in CHF compared to the specimen with a single-layer coating. The bubble observation results indicated that test specimens with higher BHTC and CHF had more active nucleation sites. The quantity of active nucleation sites plays a vital role in producing a large number of bubbles, enhancing heat transfer, and maintaining the surface temperature.

Abstract

The Silo subdistrict is one of the coffee-producing villages, with a production amounting to more than 40% of the total coffee production in Jember Regency. The coffee processing produces coffee husk waste, which is often discarded into the environment and potentially causes pollution. Coffee husk waste has a high calorific value and is suitable for use as biomass fuel to produce syngas through gasification methods. The partner for this community service is GAPOKTAN Suka Maju, located in Pace Village, Silo Subdistrict, Jember Regency. GAPOKTAN Suka Maju is led by Mr. Zainal Arifin, who has 30 members. This community service aims to provide knowledge to GAPOKTAN Suka Maju members about the environmental impact of coffee husk waste disposal and the utilization of coffee husk waste as an energy source through gasification methods. The community service method consists of pre-activities, activity implementation, and evaluation. The pre-activities include designing the gasification equipment, making the gasification equipment, and drying the coffee husk waste. The implementation consists of socializing the environmental impact of coffee husk waste disposal, the energy potential of coffee husk waste, and training in gasification equipment. The results show a significant increase in the participants' understanding of the environmental impact of coffee husk waste disposal, the energy potential of coffee husk waste, and the gasification method and equipment to convert coffee husk waste into fuel.
