Abstract

One use of alternative fuel that has the potential to be developed currently is crude palm oil (CPO). However, the use of CPO must go through a series of direct tests before it is widely applied. So the aim of this research is to carry out tests related to the use of CPO fuel and determine the effects in terms of engine performance and exhaust emissions. The fuel used in this research is CPO and B35 as existing fuel. The method used is an experimental method, through direct observation and measurement of phenomena when CPO fuel is tested for performance and exhaust emissions. The research used a diesel engine coupled to a generator and loaded with halogen lamps. The loading varies, namely 0.5; 1; 1.5; 2; 2.5; 3; 3.5; 4; up to 4.5 kW. Based on research results, the use of CPO fuel in general will produce higher power, torque and SFC, namely 2.55% each; 2.55%; and 17%. However, when comparing the thermal efficiency, hydrocarbon (HC) emissions and smoke opacity of CPO fuel, it produces a lower value of 10.54%; 15.4%; and 72% compared to B35 fuel engines. This is generally influenced by CPO fuel which has a lower calorific value, viscosity value and higher density than B35.

Abstract

Area mapping is used to find out the potential that can be explored in an area. Geographically, Glagah District is located in the area of Lamongan Regency which is located in the northern hemisphere, approximately 15 Km from the capital of Lamongan district, located at coordinates between 06° 53' 30.81'' – 7° 23'6'' South Latitude and 112° 17' 01.22'' – 112° 33'12''. Glagah District has an area of 3,888 ha of agricultural land and makes agricultural products in this area quite large. Grain production in Glagah sub-district was 29,104 tons and 18,623.29 tons of rice production in 2019. The large amount of grain obtained makes the potential for processing rice husk waste a thing that needs to be considered. One way to process rice husks is by converting rice husks into burnt charcoal, considering that the silica content in rice husk ash is quite large at 87-97% of dry weight. This method is fairly easy to do and burnt husk charcoal can be used for organic fertilizer that is beneficial for plants.

Abstract

Glagah District, located in Lamongan Regency, has a lot of potential that can still be optimized, one of which is fish processing. This area produces popular fish on the market and only becomes waste if not processed, such as small fish, fish with too many spines, and fish heads. This is the main concern in processing unsold fish as one of the main raw materials in the production of fish meal. Mapping fish processing sources aims to build and maximize fish production potential. The method used is a descriptive and qualitative method with a field survey to obtain an overview of the distribution points of fish processing sources. From the results of field surveys and mapping carried out, there are 196.2456 hectares, including swamps, rivers and reservoirs, with a production scale of around 125.4635 tons. Meanwhile, the results of aquaculture include fish ponds, rice fields, ponds, floating-net-cages, and step-net-cages, which cover an area of around 4,179.48 hectares with a production scale of 12,915.9608 tons. The use of fish includes flour, pellets, crackers, presto, and fish cake, which can add selling value. This can also be a way to reduce fish and increase the village's income.

Abstract

Dependence on fossil fuels has encouraged Indonesia to develop biodiesel, in line with the mandatory B40 policy. This study examines the effect of air velocity variations on the combustion performance of B40 (40% palm biodiesel and 60% diesel) and B100 (100% palm biodiesel) fuels. Experiments were conducted using an oil burner with air velocities of 20, 35, 45, 50, and 55 m/s. The flame temperature distribution was measured at distances of 150 mm, 300 mm, 450 mm, 600 mm, 750 mm, and 900 mm from the burner nozzle using a K-type thermocouple. The results showed that the flame temperature increased with air velocity, peaked at 45 m/s, and decreased at higher velocities. The B100 fuel produced a higher flame temperature than B40, with a maximum temperature of 1052°C. The decrease in temperature above 45 m/s is due to the cooling effect of the stronger airflow, which reduces combustion efficiency. The flame temperature also tends to decrease as the distance from the burner nozzle increases, reflecting the influence of turbulence and natural cooling on heat distribution. This study highlights the importance of controlling air velocity and measurement distance to optimize flame temperature and combustion efficiency in burner systems.
