Abstract

Technological developments have encouraged the use of generator sets as an alternative source of electricity, but this also causes problems, such as excessive heat production that disrupts comfort in the work area. This study aims to utilize sawdust and egg tray waste as heat-insulating materials for generator sets. Sawdust, which is often discarded, can be utilized to reduce the negative impacts of using generator sets and overcome environmental pollution caused by this waste. Previous studies have shown that the combination of sawdust and starch at certain temperatures can produce products with good compressive strength. The results of the ANOVA analysis in this study showed that the volume fraction of 35%: 15% with a thickness of 20 mm gave the highest heat absorption coefficient of 43.06°C, while the volume fraction of 40%: 10% with a thickness of 10 mm produced the lowest value of 35.8°C. These findings emphasize the importance of selecting volume fractions and thicknesses in increasing heat absorption efficiency, as well as providing alternative solutions for the management of sawdust and egg tray waste.

Abstract

The increasing dependence on fossil fuels drives the need for alternative energy solutions to reduce environmental impacts and reliance on petroleum. Coal, particularly anthracite, has emerged as one of the best options due to its abundant availability in Indonesia. However, coal combustion often results in the emission of harmful gases, requiring special handling. This study aims to develop coal briquettes using lime water as a binder. In addition to improving the mechanical characteristics of the briquettes, lime water is also intended to reduce sulfur gas emissions during the briquette combustion process. The briquettes were produced using a binder-to-water ratio (5:6, 5:7, 5:8, 5:9), pressing pressure (8, 9, 10 tons), and drying time (2, 4, 6 days). Compression testing was conducted following the ISO 844 standard using a Universal Testing Machine. The highest result in this study was 502 kPa (5.11 kg/cm²), achieved with a binder-to-water ratio of 5:9, a pressing pressure of 8 tons, and a drying time of 4 days. However, this result remains far below the SNI standard (50 kg/cm²).

Abstract

Coal is one of Indonesia's most abundant energy and mineral resources in the mining sector, remaining a primary energy source globally. This study aims to analyze the effect of combining anthracite coal and coconut shell charcoal powder on the compressive strength of briquettes with variations in process parameters, including temperature, heating time, and water:molasses ratio as a binder. Briquettes were produced using a composition of 90% anthracite coal and 10% coconut shell charcoal powder, with molasses binders in ratios of 4:1 and 4:3. Compressive strength tests were conducted at temperatures of 100°C and 120°C with heating times of 60 and 90 minutes. The results indicate that the optimal combination to achieve the highest compressive strength was at a temperature of 120°C, a heating time of 90 minutes, and a water:molasses ratio of 4:3, yielding a compressive strength of 506.3 kPa (5.166 kg/cm²). Increasing temperature and a higher molasses ratio significantly improved the mechanical strength of the briquettes, while prolonged heating at lower temperatures tended to reduce compressive strength due to binder degradation. Therefore, further research is needed to optimize process parameters to meet national standards and enhance briquette durability.

Abstract

The transition away from reliance on fossil fuels is critical to fostering the development of renewable energy sources, with briquettes emerging as a particularly popular alternative. This study evaluates the effects of drying processes and variations in binder fractions on the compressive strength of anthracite briquettes. The briquettes were produced using binder fractions (water: dolomite lime) of 4:10, 4:12, 5:10, and 5:12 and subjected to mechanical pressures of 8, 9, and 10 tons with drying durations of 2, 4, and 6 days. The findings indicate that the 5:12 binder fraction achieved the highest compressive strength of 544 kPa after 6 days of drying, reflecting enhanced mechanical strength due to increased dolomite lime content. Conversely, an optimal drying time of 4 days was identified, balancing moisture reduction and briquette structural stability. This research provides valuable insights for developing high-quality briquettes as efficient and environmentally friendly renewable energy sources.

Abstract

This study aims to analyze the effect of the heat treatment (quenching) process on the hardness of S55C carbon steel used as cutting blades for plastic shredding machines. JIS S55C steel was chosen as an alternative material, with hardening temperature variations of 850°C, 950°C, and 1050°C, and cooling media consisting of well water, young coconut water, and cooking oil (3 liters each). The test results showed that the hardness of the steel before heat treatment was 29.6 HRC. After heat treatment, the highest hardness was achieved at a temperature of 950°C with a value of 56 HRC using well water as the cooling medium. This study concludes that temperature variations and cooling media significantly influence the hardness of S55C steel.

Abstract

The Indonesian government recognizes the importance of transitioning away from dependence on fossil fuels. Briquettes are becoming the most popular option for overcoming fossil fuel dependence. This study examines the effect of the drying process and variation of anthracite mixture with wood sawdust on ash content and volatile matter in briquettes. The study used a factorial method with three process variables: water and molasses fractions, temperature, and holding time. The results showed that the highest ash content was obtained in briquettes with a water and molasses fraction of 1:1, while the lowest ash content was at a fraction of 2:1. The temperature and drying time also affected the ash content, where lower temperature and longer drying time resulted in lower ash content. Regarding volatile matter, briquettes with a drying temperature of 120°C and a drying time of 60 minutes produced the lowest volatile matter content. This study concludes that combining the drying process and the right mix of ingredients can improve the quality of briquettes, although the results obtained have not met the established SNI standards.

Abstract

Indonesia is a country rich in natural resources, particularly coal and coconuts. The purpose of this research is to determine the effect of drying processes and the addition of coconut shell biomass to anthracite briquettes on volatile matter content and ash content. A full factorial method was employed in this study, with three factors: drying temperature, drying time, and water-to-molasses ratio. The results show that the coconut shell biomass added to anthracite briquettes significantly affects the volatile matter content. The lowest volatile matter content, 24.8%, was observed in briquette samples dried at 120? for 90 minutes with a water-to-molasses ratio of 4:3. On the other hand, the highest volatile matter content, 28.1%, was produced by briquette samples dried at 100? for 90 minutes with a water-to-molasses ratio of 4:1. The lowest ash content, 41.1%, was found in briquette samples dried at 120? for 60 minutes with a binder ratio of 4:1, while the highest ash content, 35.8%, was observed in samples dried at 100? for 60 minutes with a binder ratio of 4:3.

Abstract

In order to satisfy the wants and desires of human life, science and technology have advanced quickly. Science and technology are developing in many facets of life. Technological advancements also happen in composite materials, which are still being studied today. Particleboard is a manufactured board created by pressing industrial waste from plantations, forestry, and agriculture together with organic adhesives. Low-quality wood waste products that may contain cellulose and lignin, such as sawdust, twigs, lathing residue, and others, can be used. The PVAc polymer was subjected to temperatures of 90°C, 100°C, and 110°C in this work, which employed a direct experimental method. The parameters used were mesh 10, 20, and 30 with a volume fraction of 60%: 40%, 70%: 30%, and 80%: 20%. In this study, the results of the largest impact strength were found in the volume fraction of 60%:40% on mesh 30 with heating at 90°C for 15 minutes amounting to 16.34 J/m2, and the smallest impact value was found in the volume fraction of 70%:30% on mesh 10 with heating at 100°C amounting to 9.28 J/m2, where these values do not meet the SNI-03-2105-2006 standard for making particle boards.

Abstract

The use of metal materials in the industrial world is increasingly widespread, so that over time metals are becoming increasingly difficult to obtain and people are required to think critically so they can look for alternative materials from the limitations of metals that are easily available and abundant, one of which is composite materials. Composite is a combination of two or more materials with different ingredients. The aim of this research was to determine the effect of thatch stalk length of 50, 60, 70 mm and a volume fraction of 35% with an oven temperature of 90°C for 45 minutes, 40% with an oven temperature of 100°C for 45 minutes, and 45% with an oven temperature of 110°C for 45 minutes when soaking the thatch stalks in 4% NaOH for 2 hours for the bending test. The highest flexural strength value was at a shank length of 50 mm with a volume fraction of 35% with an oven temperature of 90°C of 48.23 MPa. This is because the shorter the thatch stalks, the denser the thatch stalk composite looks and at a volume fraction of 35% the thatch stalks and resin stick well and the oven temperature should not exceed 90°C because if it exceeds the thatch stalks it will shrink and the flexural strength will increase. small.
