Abstract

The use of vehicles using diesel engines is increasing and has a direct impact on increasing exhaust emissions, especially particulate matter (PM), which is harmful to health and the environment. This study aims to analyze the installation of a honeycomb Diesel Particulate Filter (DPF) made of galvalum on exhaust emissions and engine temperature in a Mitsubishi L300 vehicle. The DPF was designed using galvalum material with a square honeycomb configuration and glasswool variations of 50, 100, and 150 grams. The test was conducted experimentally by comparing conditions without DPF and after DPF installation, including testing exhaust emissions, engine oil temperature, radiator water temperature, and exhaust manifold temperature. The installation of a diesel particulate filter (DPF) can reduce exhaust emissions by up to 37.1% at DPF 150 variations. DPF installation also relatively increases the temperature of radiator water, engine oil, and exhaust manifold in diesel engines. The largest temperature increase in exhaust manifold temperature is up to 8.02% compared to without using DPF at idle conditions. This temperature increase is caused by the honeycomb and glasswool structures that can create obstacles to the flow of exhaust gases. When the engine speed reaches 2000 rpm, there is an increase in exhaust manifold temperature of up to 15.09% compared to idle speed. This increase is due to faster engine speed so that combustion heat also increases.

Abstract

Sukalaksana hamlet in Cikahuripan  village, Lembang sub-district, West Bandung district has diverse regional potential and needs to be developed. However, the lack of availability of regional databases in Sukalaksana can hinder the development of the region's potential. Spatial-based region potential development aims to present spatial information that can be used in development planning. This study aims to map resource potential and analyze population pressure and capacity on land in Sukalaksana. The research method used is participatory mapping. The data is collected by using observation, interviews, documentation, and focus group discussions (FGD). Data analysis was carried out using spatial analysis techniques.  The results indicate that there are four potential that can be developed in Sukalaksana, namely the potential of human, economics, social, and land resources. Those potentials will be profitable and prosperous for the community if managed effectively and efficiently, as well as a sustainable pattern of cooperation in community life. Population pressure in Sukalaksana hamlet is 45.14, which is high category due to an imbalance in the number of population on the availability of agricultural land. The land capacity value in Sukalaksana is 0.02, which means that farmers are no longer able to carry out expansive and exploratory agricultural development.
