Abstract

The propeller is an important part of the ship's propulsion installation. Differences in propeller design can affect the propulsion performance of the ship. This study aims to determine the effect of variations in dimension ratio and propeller installation pattern on the performance of the contra rotation propeller type boat. The research was carried out experimentally by using variations of three-dimensional propeller ratios including R1 (1:1); R2 (1:1/2) and R3 (1:1/4), while the pattern of placement of the shaft tilt angle includes 15oand 20o. The flow pattern is conditioned with the waveless and wavy flow. Data collection includes boat speed and visualization of fluid flow behind the propeller which is then analyzed to obtain performance characteristics for each variation used. The results showed that the dimension ratio and the pattern of contra rotation propeller installation affected the speed and thrust of the boat, where the optimum power was obtained at the variation of the ratio R2 at a shaft tilt angle of 15owith the provision of a water flow mechanism without waves resulting in a speed of 0.576923 cm/second and under conditions of wavy at 0.523256 cm/second. The greatest thrust occurs in conditions of water flow without waves at the variation of the ratio R2 with a value of 33.23 kN and in wavy conditions of 30.13 kN. Visualization of fluid flow behind the shaft has shown the performance of the contra rotation propeller in various variations given through changes in the shape and length of the resulting path .Keywords: dimension ratio, installation pattern, contra rotation propeller, boat performance

Abstract

Kenyamanan dan keamanan dari pengendara kendaraan dapat ditentukan dari kestabilan dan Laju kendaraan. Kestabilan dari laju kendaraan ATV salah satunya ditentukan oleh ketepatan dari pemilihan dan perancangan sistem suspensi yang dipasang pada roda depan dan roda belakang. Namun dalam perkembangannya tidak semua sistem suspensi mampu memberikan kenyamanan dan kestabilan yang optimal. Dalam hal ini analisis kenyamanan dalam berkendaran difokuskan pada kemampuan sistem suspensi dalam menstabilkan guncangan. Data hasil penelitian menunjukkan bahwa dengan memperhitungkan kondisi jalan (jalan rata, sedikit bergelombang, dan bergelombang), beban yang diangkut (0 Kg, 40 Kg, dan 50 Kg), serta kecepatan yang sudah ditentukan (300 Rpm, 600 Rpm, dan 900 Rpm) pada kendaraan ATV menunjukkan tingkat kestabilan dan kenyamanan dari kendaraan ATV tersebut masih tergolong normal, karena tidak melebihi dari batas maksimum area kerja Shock Absober yang digunakan, yaitu sebesar 50 mm. Dari hasil penelitian didapatkan defleksi pegas tertinggi sebesar 22,22 mm dengan kondisi jalan bergelombang, dan dengan beban 50 kg, serta kecepatan yang digunakan 300 rpm. Data hasil penelitian didapatkan dengan bantuan alat khusus pengukur defleksi pegas yaitu sensor Ultrasonik SRF-04. Dari hasil penelitian juga ditemukan bahwa tingkat defleksi pegas tinggi ketika berada pada kondisi jalan yang bergelombang, serta semakin tinggi juga tingkat defleksi pegas ketika beban dinaikkan. Sedangkan ketika kecepatan dinaikkan maka tingkat defleksi pegas akan menurun.Kata kunci: Kendaraan ATV, Sistem Suspensi, Kondisi Jalan, Beban, Kecepatan, Shock Absober, Sensor Ultrasonik SRF-04

Abstract

Tobacco stems contain up to 35-50% cellulose, make them ideal for use as a renewable energy source. Tobacco varieties Na Oogst and Voor Oogst are characterized by their growing season. This study aims to obtain the effect of comparison of tobacco variants on the characteristics of bioethanol products. Each type is distinguished by its particle size (a) : 8-10 mm, (b) : 1.19 mm, (c) : 0.25 mm. A total of 100 grams of material was delignified using 1 liter of 4% HCl for 30 minutes. The material is then fermented using 10 grams of yeast for 10 days and distilled at a temperature of 78-80oC. Using Image J Software, the volume of the product is measured and then burned to examine the characteristics of the fire based on the duration of the flame, the percentage of color, and the dimensions of the flame. The volume of the product is also affected by particle size. The Na Oogst variant had the maximum volume with a particle size (c) of 120 ml and the lowest volume with a particle size (a) of 29 ml. The best fire characteristics were obtained in the Voor Oogst variant with particle size (c) and a blue flame percentage of 48 percent, whereas the Na Oogst variant with particle size (a) and a blue flame percentage of 10.2 percent had the lowest blue flame percentage.

Abstract

Handling heat energy in the industrial world is very necessary. Heat exchangers have a fluid system that can be designed and developed using pipes. Heat transfer in a heat exchanger is a support for the performance of a heat exchanger to make it better. In this study, a heat exchanger was tested by placing a variety of barriers on the field of heat transfer flow and the addition of variations in the flow rate on the heat pipe. This test uses a aliran inch water flow pipe and a 2.5 inch iron tube pipe and a barrier material using aluminum. Based on the test results obtained a graph of varying heat transfer increases in each barrier. Differences in barrier variations and variations in water discharge greatly affect the value of heat transfer results. The purpose of this study was to look for the effectiveness and effect of adding a flow barrier to the performance of heat transfer in a heat exchanger. Keywords: Heat Exchanger, Effectiveness of Heat Transfer Heat
