Abstract

This study aims to obtain RDF adhesives made from organic waste and to determine the effect of adhesives on RDF performance. The method used in this research is the experimental method. The data analysis technique used is descriptive quantitative. The various types of adhesives used are waste banana peels, cassava peels, and cocoa peels. The ratio of the composition of RDF and adhesive waste is 9:1 mass unit. RDF material is mashed and filtered using mesh 10, after being mixed with adhesive then pressed with pressure 5; 7.5; 10; and 12.5 bar, then dried in an oven at 150 0C for 3 hours and dried in the sun for two days. RDF testing was carried out by proximate for water content and ash content, by bomb calorimeter for calorific value, and by Shore Hardness Test for hardness. The results showed that waste banana peels, cassava peels, and cocoa peels can function as RDF adhesives for organic waste and meet industry standards, replacing plastic or flour-type adhesives that have been used so far. The calorific value, moisture content, and ash content of RDF with the three adhesives were (5495.410 cal/g, 7.78%, and 16.74%) for banana peel adhesive, (6068.007 cal/g, 6.18%, and 17.14%) for cassava peel adhesive and (5,504.438 cal/g, 5.36%, and 17.19%) for cocoa shell. The results of the hardness test of RDF materials with the three adhesives each with variations in pressure showed (6 Shore D 5 bar, 8.5 Shore D 7.5 bar, 13 Shore D 10 bar, and 19 Shore D 12.5 bar) for banana peel adhesive, (6.5 Shore D 5 bar, 10 Shore D 7.5 bar, 14 Shore D 10 bar, and 20 Shore D 12.5 bar) for cassava peel adhesive and (8 Shore D 5 bar, 12 Shore D 7.5 bar, 18 Shore D 10 bar and 24 Shore D 12.5 bar) for cocoa shell adhesive.

Abstract

This research aims to analyze traffic characteristics and their impact on the level ofservice on Jalan Jenderal Gatot Subroto in Pacitan Regency. This road section isone of the important arteries that connects various areas in Pacitan Regency, andhas a big influence on mobility and the local economy. The research methodinvolves collecting traffic data through direct observation, traffic volume surveys,and measuring vehicle speeds during peak and off-peak hours. The collected datawas analyzed using road capacity analysis methods and traffic simulation models toassess the level of service (LOS) on the road section. The results of the researchshow that the characteristic pattern of Jalan Gatot Subroto, vehicle volume isdominated by motorbikes on holidays or weekends with a maximum volume of200.06 cur/hour with a maximum average speed of 31.52 cur/hour at monitoringpoint 2 which is in front of the Bus Terminal. Pacitan with the level of serviceadapted to Jalan Jenderal Gatot Subroto Pacitan from the four points surveyed was2.35, which was obtained at point 2 with a service level of D with a flow dominatedby motorbikes towards the beach tourist attraction at a stable and tolerable speed.These findings provide important insights for traffic planning and management, aswell as recommendations for infrastructure improvements to increase trafficefficiency and safety in the region.
