Abstract

Composites using natural fibers are being widely developed and researched, this is because natural fibers are easy to find and abundant. In this study, the natural fibers used were bamboo fiber and banana stems. Banana fiber has good mechanical properties and is easy to find, while bamboo fiber is easy to find and has a low density. In this study, the aim was to determine the effect of fiber orientation and treatment on the tensile strength and toughness of natural fiber reinforced composites using a polyester matrix. The variation of the fiber orientation used is 30o and 90o, and the fiber treatment used is alkali and bleaching treatment. Based on the research results, the 90o angle with fiber bleaching treatment has the highest tensile strength value, which is equal to 37.33 MPa with a modulus of elasticity of 5 GPa. As for toughness through impact testing, the highest value is 2.74 x 10-2 J/mm2 at an angle of 90o with bleaching treatment.

Abstract

This study aimed to analyze BKI Grade (KI-A) plate material using the pre-heat process to determine tensile strength and hardness. The method involved welding with shielded metal arc welding (SMAW) type. The pre-heat variations used several temperatures, such as 50⁰C, 120⁰C, 220⁰C, and without heat treatment. The tensile strength obtained specimen without pre-heating had the lowest tensile strength of 442.64 MPa, and the specimen with pre-heating to 220⁰C had the highest average tensile strength of 450.11 MPa. The result showed that tensile strength was proportional to the pre-heating temperatures given. The hardness observation found that the hotter the pre-heating temperature obtained, the higher the hardness value of the base metal and HAZ would obtain. It was different with weld metal which would decrease. From those two parameters, it could be concluded that the most optimal pre-heat temperature was 220⁰C.

Abstract

This study shows that the condition of the well water tested based on physical, chemical and biological parameters to determine the feasibility of the water used by the surrounding community still meets the required quality standard thresholds. Although somewhat polluted because of the mining. Underground water in the karst area of Gunungkidul Regency is safe as raw water for drinking by residents and meets the standards set by the Indonesian Ministry of Health and Government Regulation Number 82 of 2001 concerning Water Quality Management and Water Pollution Control. If used as drinking water, it still has to go through water treatment or be heated to a certain boiling point, because it contains bacteria that may be harmful to humans.

Abstract

This paper presents an on-site investigation of a fuel consumption comparison between a Front Wheel Drive (FWD) and Rear Wheel Drive (RWD) vehicle as those are the two most common drive type used in the commercial vehicle. The study focuses on the fuel consumption rate by comparing the average distance achieved by one liter of fuel using the same type of engine. The road test was varied from the normal highway, uphill, downhill, as well as normal city road to give more insight about the fuel consumption characteristics of each variation. From the results, it is known that each road type gives significant different characteristics to the fuel consumption. Also, the comparison between FWD and RWD regarding fuel consumption gives interesting results for further vehicle transmission developments.

Abstract

PT. Rencana Mulia Baratama is one of the companies engaged in coal mining in Long Beleh Village. The area of WIUP OP owned is 3,993 ha with a Production Forest Area of 2,630.4. The drainage system applied at PT. Mulia Baratama's plan is Mine Dewatering, which is by flowing all runoff water into a well (sump) to be pumped out of the mining area which flows into the settling pond. The well is a place that serves to hold a temporary amount of water before being pumped out The actual volume of the well in pit 1 is 58,000 m3. The planned rainfall period based on the 5-year rain reset period is 179.473 mm/day and the duration of rain is 2.4 hours per day. So that the amount of rain intensity calculated by the monobe equation is 37.39 mm/hour. The total water discharge entering the mining site is 58,817,254 m3/day which comes from runoff water discharge of 13,260,552 m3/day and rainwater discharge of 45,556,704 m3/day. The pumping discharge carried out is 462.4 m3/hour using one type of centrifugal pump 200x150 using Rpm 150 so that the total water discharge that can be drained in a day is 7,398.4 m3/day.

Abstract

Fishing vessels in Indonesia conventionally use diesel engines as their main propulsion engine. However, the use of diesel engines has quite a bad impact on the surrounding environment. So the latest innovations using alternative energy are needed. One of them is the use of electric engines as a replacement for diesel engines in the ship's main propulsion engine. The use of this electric machine will have a friendly impact on the environment. Apart from that, you don't need to spend a lot of money to maintain this electric machine. We can see this by comparing the ship's thrust requirements with maximum speed.

Abstract

This study fabricated a novel sulfonated poly-eugenol/titanium dioxide nanocomposite membrane as an alternative polymer electrolite membrane (PEM) to direct methanol fuel cells (DMFCs), addressing the high cost of PEM, a major challenge for fuel cell (FC) commercialization. Sulfonated poly-eugenol (S-PE), synthesized by polymerizing eugenol with sulfuric acid, incorporated sulfonic acid groups to improve proton flows conductivity. Titanium Dioxide nanoparticles were incorporated into the sulfonated polymer matrix, forming a mixed membrane nanocomposite. Scanning electron microscopy confirmed a homogeneous TiO2 distribution in the polymer. The membranes' physicochemical properties, including air absorption, swelling, and methanol absorption, were evaluated and compared to commercial Nafion. The S-PE and TiO2nanocomposite membrane with 25% (S-PE) and 5% TiO2 exhibited higher water and methanol absorption than Nafion, but lower proton conductivity. However, its low methanol permeability can potentially improve fuel efficiency in direct methanol fuel cells. Incorporating TiO2 into sulfonated poly-eugenol represents a promising strategy for developing low-cost, efficient PEM for DMFCs applications.
