Abstract

This study investigates the effect of using Liquefied Petroleum Gas (LPG) as an alternative fuel to Pertalite on the performance, energy efficiency, and operating cost of a 6.5 HP gasoline engine-driven water pump. Experiments were conducted at three engine operating conditions: minimum, average, and maximum engine speeds. The evaluated parameters included engine speed, water discharge, hydraulic power, shaft power, brake specific fuel consumption (BSFC), thermal efficiency, overall system efficiency, and fuel operating costs. The results indicate that the pump's hydraulic performance, as measured by water discharge and hydraulic power, is not significantly affected by the type of fuel used. However, engines that use Pertalite tend to have slightly better thermal and system efficiencies than LPG engines. From an economic perspective, LPG offers a substantial advantage, with lower operating and energy costs per unit of power. Therefore, despite Pertalite's slightly superior technical efficiency, LPG is a more economical alternative fuel for long-duration water pump applications.

Abstract

Moisture-induced degradation remains a critical reliability issue in photovoltaic (PV) modules, particularly in humid tropical climates. While biomass-derived carbon materials have been widely investigated for electrochemical applications, their use as functional supporting layers in PV modules remains limited. This study develops potato-derived carbon nanofibers through moderate-temperature carbonization (700 °C, N₂ atmosphere) followed by electrospinning. Structural and chemical properties were evaluated using XRD, FTIR, Raman spectroscopy, and BET surface area analysis. Morphology and fiber diameter distribution were examined via SEM. Electrical conductivity was measured using a four-point probe method. Water vapor permeability (WVP) and biodegradation behavior were assessed to evaluate durability and moisture regulation capability. The synthesized material exhibits predominantly amorphous turbostratic carbon with characteristic D and G Raman bands (ID/IG ≈ 0.92), specific surface area of 186 ± 12 m²/g, and electrical conductivity of 3.8 ± 0.4 S/m. Nanofiber diameters range from 72–108 nm (mean ± SD). Controlled WVP (3200–4100 mg/day/L) and moderate biodegradability (8–12% mass loss over 14 days) indicate balanced vapor diffusion and structural integrity. The results demonstrate the feasibility of potato-derived carbon nanofibers as sustainable moisture-regulating supporting layers in photovoltaic modules.

Abstract

Making fishing rod weight pendulums using a metal casting process, namely by pouring molten metal into a mold, to produce the final shape of the product according to what we want. The aim of metal casting activities is to produce fishing rod weight pendulums using permanent aluminum molds, and identify defects in the casting results. The method used is a simple method, the materials used are portable stoves, portable gas cans, can melting furnaces, solder tin, aluminum molds, wire. From this research, it was obtained that casting results had several defects at the end of the casting process, namely the defects that occurred were mold shift defects (deformation defects), and hole defects (porosity defects). Through carrying out research on metal casting activities using simple tools, it was concluded that the results obtained from the metal casting process using aluminum molds were not good because there were many defects in the castings.

Abstract

Metal casting is a manufacturing process that uses molten metal and molds to produce shapes that closely resemble the final geometry of a finished product. The molten metal is poured or pressed into a mold cavity that matches the desired shape or design. The objective of this research is to create a mold pattern using plastilin as a medium, identify the defects in the casting results, evaluate the advantages and disadvantages of using plastilin molds, and determine the shrinkage that occurs in the cast product. The research method applied in this metal casting process is the experimental method, where the mold is made from plastilin. The results show that the casting process led to several defects in the final product. The observed defects include porosity, a rough surface, and shrinkage. The porosity defects, characterized by small holes, were caused by trapped air during the pouring of the molten metal. The rough surface was due to the plastilin mold melting when the molten metal was poured into the mold. It can be concluded from this study that using plastilin as a mold medium is less effective, as the plastilin mold melts during the casting process, resulting in many casting defects. The pouring temperature affects the level of porosity in the casting, where higher pouring temperatures lead to increased porosity.

Abstract

Metal casting is a manufacturing process that is widely used in industry. This research aims to examine the tin solder casting process using sand casting molds to make spoon handles. Soldering tin was chosen because it is often used in the electronics industry to connect components. The method used in this test is Sand Casting using a silica sand mold. The silica sand molds used include disposable molds or Expandable Molds. The results of tin solder casting show that the silica sand sand casting mold produces baby spoon handle products. This research shows that casting tin solder using silica sand sand casting molds produces size error defects which result in dimensional changes between the sample object and the casting product. These dimensional changes indicate that the dimensions of the casting product are smaller than the sample object. Apart from that, there are also holes in the form of air cavities or porosity experienced by casting products.

Abstract

Abstract This study aims to analyze the efficiency and cutting quality of a plastic ring cup cutting machine as a solution to the manual separation process, which is time-consuming and less effective. An experimental test was conducted using a cutting machine with a design capacity of 100 kg/hour and a 1 hp electric motor operating at a speed of 627.2 rpm. The testing focused on production capacity efficiency, cutting time, accuracy, and the quality of the cut. From ten trials, the average actual output was 44.69 kg/hour with an efficiency of 44.69% compared to its maximum capacity. These results indicate that several factors, including blade sharpness, machine size, and operational conditions, influence the machine’s performance. In terms of quality, some samples showed rough or incomplete cuts due to reduced blade sharpness. Nevertheless, the cutting machine proved capable of significantly improving the speed and efficiency of plastic waste processing on a small scale. With design improvements and proper blade maintenance, the machine’s performance can be optimized, making it a practical and environmentally friendly alternative for plastic waste processing equipment.
