Abstract

The reduction of carbon monoxide (CO), unburnthydrocarbon (UHC) emission and fuel consumption on spark-ignition four-stroke engine is continuously attempted. The purposes from this research were to determine the effect of Hydrocarbon Treating System (HTS)  on levels of CO, UHC and fuel consumption. This is an experimental research. Its is conducted by comparing the exhaust pollutant concentration such as carbon monoxide, unburnt hydrocarbon and also fuel consumption between standard engine setting and Hydrocarbon Treating System applied. The research variable are HTS flow rate from Q1 = 0 cc/s (without HTS), Q2 = 1,5 cc/s, Q3 = 2 cc/s, Q4 = 2,5 cc/s, and Q5 = 33 cc/s. The research will be done in three conditions which are low, medium and high rotation. The result showed that Hydrocarbon Threating System decrease fuel consumption up to 19,43% with flow rate Q5 = 3 cc/s, but on the other hand it increase CO emission up to 80.84% with flow rate Q5 = 3 cc/s and UHC emission level up to 124.75% with flow rate Q5 = 3 cc/s from engine standart condition.

Abstract

Traffic accidents are terrible scourge that occur in many countries, specially for developing countries where transportation affairs like tangled yarn. Besides functioning as an engine compartment cover, the hood of modern compact SUV can also help to manage the impact energy of a pedestrian’s head in a vehicle-pedestrian impact. This paper presents outer hood design of Esemka R2 that has a potential to improve hood’s ability and also to absorb the impact energy of a pedestrian’s head. The developed method for the design of an outer hood configuration aims to provide a robust design and homogeneous of Head Injury Criterion (HIC) for impact position at WAD 1000 and three different thicknesses (1.25 mm, 1.35 mm & 1.50 mm) of outer hood panel of Esemka R2 compact SUV, taking into consideration the limited space available for deformation. The non-linear Finite Element Analysis (FEA) software (Explicit Dynamics) was used in this research to simulate the testing procedurs of head impact for child pedestrian. The results show that the average of comparison dimensional of outer hood panel of Esemka R2 was 4.89 mm. The minimum of deformation space meet the requirement for HIC value which required obtaining robust and homogeneous head impact performance. Outer hood thickness and materials were identified as the factors to influence the stress and HIC value of the hood. By comparing all outer hood panels, aluminium alloy as the best selected material which has the lowest value is 32.78% for the pedestrian protection.

Abstract

Penelitian ini bertujuan untuk menganalisa sifat mekanik material komposit berpenguat tempurung kelapa sebagai bahan dasar campuran kampas rem. Untuk menggantikan kampas rem berbahan asbes yang berbahaya bagi kesehatan dan lingkungan. Metode yang digunakan mencampurkan komposisi bahan kampas rem yang diteliti bermatriks phenolic resin penguat serbuk tempurung kelapa dengan limbah serbuk logam (aluminium, kuningan, barium sulfat, kalsium karbonat, grafit) dan fiberglass. Beban penekanan 10 ton serta waktu pengepresan campuran material yaitu 5 menit pada temperatur 150°C, 8 menit pada temperature 130°C dan 10 menit pada temperatur 120°C. Pengujian gesek dalam kondisi kering dan basah dengan pembebanan 15 kg serta pengujian kekerasan dengan durometer. Hasil penelitian yang didapatkan yaitu nilai keausan dan kekasaran kampas rem sangat dipengaruhi oleh komposisi material penyusun serta waktu dan temperatur penekanan.

Abstract

Vocational students need some skills that will be used when students finish their studies at school. One of the expected skills is the ability to draw using the AutoCAD program. Where the final ability is expected of the students will be able to create engineering drawings in the form of 2-D models. The purpose of the training program is to develop and improve the technical drawing skills of the XII class students in using the AutoCAD program. Therefore, the students of class XII SMK have the ability to draw machine components and other engineering drawings in 2-D format. The method used in this training program through pre-test instrument, AutoCAD module, discussion, display through slide how to make machine image in 2-D formats and practice how to make the engineering drawing then evaluated with post-test. The result of this program is the improvement of the ability of grade XII students in drawing machine components and other engineering drawings in 2-D format.

Abstract

Composite is a combination of materials formed from mixing between two or more of the forming materials. This research aims to determine the effect of variations in fiber length with lengths of 4cm, 6cm, and 8cm with a volume fraction of OPEFB fiber of 30% and NaOH alkaline immersion for 2 hours. The tests carried out were tensile testing using ASTM D3039 and bending testing using ASTM D7264. Based on the study's results with the 30% OPEFB fraction with the highest tensile strength yield, the 8cm fiber length of 13,33 MPa was achieved. Meanwhile, the lowest value was achieved with a length of 4cm of 3,2MPa.
