Abstract

Penggunaan energi bahan bakar dari fosil terbesar berada pada sektor transportasi, industri dan pembangkit daya atau listrik. Tujuan dalam penelitin ini adalah untuk mencari efektifitas rasio campuran limbah kotoran sapi dan limbah pohon pisang terhadap hasil pembuatan bio gas. Penelitian menggunakan varasi bahan campuran yang meliputi kotoran sapi dengan campuran limbah pohon pisang, air dan EM4 dengan rasio A (1:5:5:10:1), B (5:7:10:1) dan C (7:5:10:1). Proses fermentasidilakukan selama 10 hari dengan disertai pengukuran tekanan gas/hari menggunakan manometer U dan uji nyala api. Analisis nyala api meliputi pengukuran luas penampang api, warna api dan temperatur api. Hasil penelitian menunjukkan bahwa rasio campuran berpengaruh terhadap karakteristik gas produk. Tekanan gas tertinggi pada campuran C sebesar 251,74 Kpa dan terkecil pada variasi campuran B sebesar 189,81 Kpa. Sedangkan produk api paling unggul ditunjukkan pada variasi campuran C dengan luas penampang api 48.3 cm2, didominasi warna api biru 75.56%. Sehingga diketahui efektifitas rasio campuran bahan terbaik di pengaruhi oleh rasio bahan limbah kotoran sapi hal ini disebapkan oleh kandungan CH4 dari kotoran sapi lebih besar dibandingkan dengan limbah pohon pisang..Kata kunci: limbah, pohon pisang, kotoran sapi, biogas, efektifitas

Abstract

Unwanted grass growth on land will cause problems for humans. Generally, the sickle is a tool that is often used to cut grass. The use of a sickle has several disadvantages, namely using manual labor, in some cases there is a narrow-angle that makes it impossible to cut with a sickle. This study uses variations of 2, 3, and 4 blades with motor rotation speeds of 666 RPM, 1713 RPM, and 3454 RPM. The data collection method is done by determining the mass of grass by 25 grams, then the grass is arranged and moved closer to the blade with a cutting time of 10 seconds. The shortest cut grass results were obtained on the number of blades 4 with a motor rotation speed of 3454 RPM, which is 10.92 mm. The difference in mass of grass clippings in the variation of blade 4 with RPM 1 and 3, which is 4 grams, indicates the overall cut grass Keywords: blade, motor rotation speed, grass cutted

Abstract

Hammer mill is a machine for crushing hard materials and flour. By modifying the hammer shapes and varying the motor rotation speed, it is hoped that it will be able to crush the shells into powder with different product dimensions. The quality of the product produced will describe the performance of the hammer mill machine. Experiments were carried out by making the ends of the batter dimensions 1, 2 and 3 cm with a motor speed of 1000 rpm, 1100 rpm and 1200 rpm. The highest yield of the 3 cm bat type is at 1200 rpm at 96.7%. Keywords: Clamshell, Hammer Mill

Abstract

Window film is a thin layer on car glass that functions as a medium for repelling sunlight. This study aims to determine the effect of percentage of window film density on the thermal and lighting distribution of the vehicle cabin. This research was conducted using a room model measuring 50x50x30 cm. The variation of window film uses two brands of Ultima and 3M, with the respective percentages of 40% and 60%. When the experiment was carried out in an open space, the irradiation process was carried out for 2 hours using the sun's rays at 11.00 - 13.00 WIB in each variation. Temperature measurement uses a digital thermometer on the surface of the coated glass (T1) and indoors (T2), while the measurement of light intensity uses a lux meter that is placed outdoors (I1) and indoors (I2). Data analysis using the equations of temperature rate and effectiveness of heat and light reduction. The results showed that the difference in the percentage of glass film density affected the rate of heat transfer and the intensity of the light entering the room. The heat transfer rate tends to increase in Q1 with a value of 58375.61 joules, and decrease in Q2 with a value of 1160.46 joules in the variation of 3M glass film brands with a 60% concentration level. Meanwhile, the average temperature increase rate is 0.002 ℃ / minute for all variations of window film brands with a light intensity of 0.007 - 0.008 lux. Keywords : window film, temperature rate, light intensity, heat transfer.

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
