Abstract

This study is devoted to the performance and emission evaluation of automotive diesel engine as affected by coco biofuel utilization. The concentration of palm biodiesel used in the test was ranged from B0 (pure petro-diesel), B10, B20, B30, B50 and B100 (pure biodiesel). The engine performance was evaluated through torque, power, and specific fuelconsumption, while the emission was evaluated through carbon monoxide (CO), hydrocarbon (HC), particulate matter (PM), carbon dioxide (CO2), and NOx pollutants. The result shows that higher content of palm biodiesel can reduce the emission of CO, HC, PM, and CO2. It was found that the addition of biodiesel could increase the power and torque. Further more, NOx also decreased when the content of palm biodiesel increases, which is in contrast with those generally found in the previous non palm biodiesel studies.Keywords: palm oil biodiesel, petro-diesel, carbon monoxide, hydrocarbon, particulate, matter, O2,and NOx pollutants

Abstract

A biomass stove is one of the alternative tools made from bio pellet as a substitute for LPG gas stove (Liquefied Petroleum Gas). Biomass stoves are currently less known by the public due to their traditional use and lack of socialization of biomass fuels. Starting from the problem, biomass stoves currently need further development in order to be used in daily life. Therefore, it is necessary to develop the biomass stove by adding a 12-volt lithium-ion battery as the main power source and a circuit dimmer as a fan speed regulator. The treatment variable in this study is to provide variations in fan speed. Variations used are low, medium, and high fan speeds. The main fuel of the biomass stove is a wood grain bio pellet with the weight of each bio pellet used per treatment as much as 300 grams. The method used in this study used a one-way ANOVA that produced a difference in variation had no real differences and had a noticeable effect on the rate of combustion, the temperature of the fire, and the length of time the water was boiled.

Abstract

Rapid and massive damage on peatland mainly due to conversion to a production system in the presence of perennial crops for the purpose of financially profitable agribusiness, such as oil palm plantations and other industries, can lead to increased greenhouse gases. Greenhouse gas emissions are influenced by biophysical processes are complex, such as peat decomposition and compaction, nutrient availability, soil water content, and soil water content. When land clearing increased significantly in the area of peatland is not followed by the application of sustainable agriculture, then, will peat land would become flammable and the greater the volume of CO2 gas that emits into the atmosphere that causes global warming and climate change. This paper reviews about the expansion of agriculture and plantations on peatland and action needs to be done by following sustainable agricultural systems. Noting the condition of peatland that have been severely damaged due to the expansion of oil palm plantations, the mitigation and adaptation in the land through sustainable agricultural system is highly recommended to reduce the more severe damage to the peatland areas and minimize the release of CO2 into the atmosphere.

Abstract

Abstrak. Sampai sekarang, penggunaan biodiesel khususnya biodiesel dari kelapa di Indonesia belum menyentuh kepada penggunaan sebagai bahan bakar, baik untuk bahan bakar transportasi ataupun bahan bakar industri. Dari perkembangan yang ada terutama di luar negeri bahan bakar biodiesel sudah digunakan sebagai bahan bakar transportasi meskipun hanya dalam bentuk campuran. Ketersediaan bahan bakar minyak bumi semakin hari semakin terbatas. Selain karena alasan ketersediaan minyak bumi yang terbatas, pengembangan produk biodiesel dari minyak tumbuhan seperti minyak sawit, juga diarahkan pada sifat bahan bakunya yang dapat diperbaharui. Secara teknis hasil pengujian laboratorium terhadap unjuk kerja mesin diesel menghasilkan bahwa campuran biodiesel 30% dengan 70% solar mempunyai daya maksimum 5,36 HP pada 2.190 rpm lebih rendah bila dibandingkan dengan solar 100%, 5,41 HP pada 2.200 rpm. Sedangkan torsi maksimum campuran biodiesel 30% adalah 1,748 Nm lebih rendah dari solar 100% 1,761 Nm. Kandungan carbon monoxide campuran biodiesel dan hydro carbon campuran 30% biodiesel dengan 70% solar juga lebih rendah daripada solar 100%.Improved Performance of Diesel Engines With the Production of Biodiesel From Coconut (Coconut Nufera) and Performanced Based on Direct Injection System With TransesterificationAbstract.

This research aimed to develop and a rice cleaning and grizzly-type sieving machine which also evaluates its performance. It consisted of designing, assembling, and performance evaluating of the machine. The desired machine was developed in six main components, i.e., power source, hopper, rice cleaner, rice siever, outlets, and machine frame. The research used three rotational speed treatments (Slow-Middle-Fast or L-S-C rotations) for data collections, whereas the parameters of performance testing consisted of work capacity, engine rotation speed, airflow rate, pulley rotational slip, and grain loss percentage. Engine rotation speeds at L-S-C treatments are 1654, 1817, and 1979 rpm and resulted in 7.04, 7.79, and 8.50 m/s, respectively, for airflow rates produced by the suction from a blower. The most significant rotational slip is occurred at Pulley-4 resulted in 3.27% (operating without samples) and 1.70% (operating with samples); this pulley transmitted rotational power to vibrate the 10-mesh grizzly sieve. The work capacities at L-S-C rotational treatments were 78.5, 81.6, and 146.7 kg/h, respectively. The optimal separation of brans was at C-rotational treatment, while the optimal separation of groats was at L-rotational treatment. The high percentage of grain loss occurred along with a reduction in speed that made the machine work ineffectively.

Abstract

Okra is famous as super food sources that prevent diabetes and reduce cholesterol. To meet the increasing demand for okra, it is necessary to develop plantation for okra cultivation. In this sense, land suitability analysis for okra plantation is needed as base information to develop the plantation development strategies. This study aimed to identify the okra plantation development strategies in Jember Regency. The strategies involved the technology recommendations needed to improve land conditions. Land suitability evaluation parameters were analyzed using ArcGIS software. The results of the analysis were used to determine internal and external factors in the SWOT (strengths, weaknesses, opportunities, and threats) analysis to determine the technology needed. Results showed that suitable area for okra plantation was divided into class S1 (highly suitable) of 56.85%, and class S2 (moderately suitable) 43.15% of the area. Moreover, based on SWOT analysis the proposed technology strategies for 7 sub districts were in the quadrant II, meaning had weaknesses. Increasing compost as fertilizer was recommended to increase N, K, and P in the soil as well as to increase soil solum. In addition, irrigation and drainage system was proposed to solve problems regarding rainfall. Recommendation to reduce sloping area included terracing development. Keywords: GIS, Land suitability analysis, Okra (Abelmoschus esculentus L.), Plantations development strategies, SWOT.
