Abstract

The purpose of this study was to analyze the implementation, constraints and impact of the implementation of the cash for work program in Karang Gading Village on the poverty of the people of Karang Gading Village, Labuhan Deli District, Deli Serdang Regency. This research uses a qualitative descriptive method, to make descriptions, pictures, or paintings systematically and accurately about the facts, characteristics and relationships between the phenomena being investigated. The results showed that the implementation of the cash for work program from the Karang Gading Village Fund on the concrete rebate activity for sirtu hoarding in Dusun VI for the 2020 fiscal year the results were not optimal, this can be seen from four aspects in accordance with Edward III's theory of communication that is not yet optimal, Resources are inadequate, the Bureaucratic Structure is not completely well organized, and only the Disposition / Attitude is sufficient, the obstacles faced are inadequate human resources, and minor conflicts in the form of protests from villagers who are not empowered as workers or recipients. Village Cash Workforce Wages and rumors circulating that the Village Head and TPK only empower families and relatives as workers / recipients of Village Cash Workforce wages.

Abstract

As the population increases, waste generation and composition will increase. Therefore, there is a need for planned and effective waste handling so that the problem of waste can be resolved in accordance with the 3R (Reuse, Reduce, and Recycle) concept. The aim of this research is to calculate the amount of waste generation and the composition of domestic waste produced by the residents of Medan Denai, and also devise the type of 3R Waste Treatment Plant for the District of Medan Denai. The method for measuring the generation and composition of waste are based on SNI 19-3964-1994, that is based on income level. Meanwhile, the typical planning of TPS 3R is obtained from the calculation of waste generation which is associated with the projection of population. The result showed that the average of household waste in the District of Medan Denai was 0.265 kg/person/day or 1.4 l/person/day. The composition of household waste generation in the District of Medan Denai is dominated by food waste 65.38 %. It is estimated that in 2026, the waste generation produced in the District of Medan Denai would reach about 41,593.7 kg/day. The economic potential that can be generated by using 3R concept is estimated reaching about Rp11,687,190 - Rp85,370,971 per day. Managing waste with 3R concept require a TPS with 1,488.24 m2 of area to process the household waste, with the estimated cost required to build the facility is Rp598,960,540 and the operational cost is Rp104,000,000 per month.

Abstract

The discrepancy between the use of vehicle fuel types and the vehicle's technical specifications is expected to affect exhaust emissions. This study aims to examine the effect of using four types of fuel with different octane number specifications on two four-wheeled motor vehicles with an EFI fuel delivery system on exhaust gas emission parameters of carbon monoxide (CO), hydrocarbon (HC), carbon dioxide (CO2) and non-emitting gases Oxygen (O2). With a quantitative experimental approach method using the Automotive Emission Analyzer and simple linear regression analysis, the results showed that the use of variations with octane numbers RON 98, RON 92, RON 90, and RON 88 fuels at the same time as variations in engine speed (1000 – 3000) RPM showed an effect on concentration. HC and CO emissions decreased with each increase in the octane number of fuel, RON 92 fuel with the lowest average CO / HC (0.0013% / 0.46 ppm) and RON 98 with the lowest average CO / HC (0.0026% / 0 ppm). The use of RON 92 fuel is more effective and inexpensive to apply to vehicles with an EFI fuel delivery system (with compression of 1:10/10.2) compared to RON 98 fuel which emits higher CO and HC emissions at low engine speed (1000 -1500) RPM.
