Abstract

Pollution of plastic waste to the environment is a big obstacle because plastic waste is difficult to recycle directly. Waste management should implement processes, such as reduce, reuse, recycle and replace potentially waste items into Recycle (Replace) materials. Recycling plastic waste has the potential to change what was previously waste that has no economic value into an item that has economic value and at the same time reduces environmental pollution problems. The purpose of this study was to design a plastic waste chopper with a capacity of 85Kg. The method used in this research is the method of design and calculation. The results of the design of a plastic chopping machine with a capacity of 85Kg, the dimensions of the shaft length are 50cm, the shaft diameter is 8cm and the cutting blade holder is connected to the shaft. The blade is designed so that it can be adjusted forward and backward according to the thickness of the plastic to be chopped. There are 6 dynamic blades and 2 static blades. The cutting angle of the blade is 45°. The hooper design has dimensions of 40cm long, 40cm wide and 60cm high with a plate thickness of 0.8mm. The frame of the garbage chopper has dimensions of 40cm long, 40cm wide and 70cm high. The result of calculating the engine capacity on a plastic chopper with a capacity of 85kg hour is 1400g minute.

Abstract

This study aims to identify the potential utilization of banana stem fiber (BSF) as a locally sourced composite material to support building infrastructure in North Maluku. The research focuses on analyzing the tensile and impact properties of the composite. An experimental method was used, incorporating different treatment durations for the fibers by immersing them in liquid smoke for 1, 2, and 3 hours. The treated fibers were then heated at 40°C for 30 minutes. The next step involved fabricating BSF-reinforced composite specimens by preparing the resin and fibers, with a fiber length of 10 mm and a composition of 30% BSF and 70% resin. Tensile and impact tests were conducted to evaluate the mechanical properties of the composites. The results showed that the tensile strength of the P3J composite increased to 88.351 MPa, representing a 3.79% improvement compared to the untreated composite (TP). Meanwhile, the impact strength showed the highest increase after 1 hour of immersion, reaching 10.911 KJ/m, which is 25.45% higher than TP. These findings indicate that liquid smoke treatment enhances the tensile and impact properties of the composite.

Abstract

The intensity of solar energy is an important factor in viewing the performance of the thermoelectric generator (TEG). Most studies only look at the effect of treatment on the TEG module in the form of cooling mode and its materials. Therefore this study examines the effect of the solar intensity value on the magnitude of the module voltage. On the hot side of the module are placed heat absorber plates of copper, Fe and aluminum plates as well as non collector plates. Modules are cascaded and connected in series as many as 14 modules per plate, so that a total of 56 TEG modules are used. Data collection is carried out simultaneously on all plates. The test results show that the increase in solar intensity is liner with the magnitude of the TEG module voltage or in other words the correlation is positive. The data also shows that copper collector plates produce the highest voltage difference, followed by Ferro, Alumina and no-plates at ∆V 0.871, 0.805; 0.369 and 0.153 V, respectively
