Analisa Pengaruh Penggunaan Tabung Induksi Nova Dash Racen Terhadap Emisi Gas Buang Pada Sepeda Motor Honda Beat
Full text linkThis study aims to analyze the effect of using the Nova Dash Racen induction tube on exhaust emissions in Honda Beat motorcycles. Exhaust emissions are a key indicator for assessing the negative impact of motor vehicle engines on human health and the environment. The research uses an exhaust emission testing method on a Honda Beat motorcycle before and after the installation of the Nova Dash Racen induction tube. The measured emission parameter is carbon monoxide (CO). The results indicate that using this induction tube can reduce harmful exhaust emissions. At 1500 RPM without the tube, the CO content is approximately 9.6% to 9.9%, while with the tube, the CO content is around 7.8% to 7.9%. At 2000 RPM without the tube, the CO content ranges from 8.8% to 9.1%, whereas with the tube, the CO content is around 7.7% to 8.2%. At 2500 RPM without the tube, the CO content is approximately 9.0% to 9.7%, and with the tube, the CO content is around 7.4% to 8.1%

Full text linkIn the current era of globalization, transportation is a very important part in the development of a country or region, the problem that often occurs at this time is that the bow of the ship at its base will often collide when it will lean into the port (jeti), when the impact occurs over time the bow and the inside will not be able to withstand the impact which will cause dents or deformation. The purpose of adding this construction is to increase the strength of the bow of the barge because the bow is often docked to the jeti (dock) and is easily deformed. The purpose of the author in this case uses a solution using the Ansys application. ANSYS is one of the software used to analyze various kinds of structures, fluid flow, and heat transfer from several other analysis software, namely Nastran, Catia, Fluent, and others. The stages of solving the problem to get the stress and strain distribution on the bow due to static loads using the finite element method (FEM) are considered symmetrical in shape and loading so that the modeling is made ¼ part).ANSYS is a product of the ANSYS Inc. company, ANSYS is a product of ANSYS Inc. which is used for Simulation and Engineering Design of 3D products. the result of this study is the impact force due to collisions received by the ship of = 8.528 tons
Pengaruh Variasi Tekanan Proses Pengepresan Dan Komposisi Bahan Perekat Terhadap kekerasan Dan Kerapatan Briket Tempurung Kelapa
Full text linkThe fuel energy crisis and the currently dwindling availability of fuel oil have given the impression that now is the time for us to switch to alternative fuels, one of which is charcoal briquettes. The aim of this research was to determine the effect of variations in pressing process pressure and the ratio of binding materials (starch, sago, and fox glue) on the hardness and density of coconut charcoal briquettes and to obtain good quality in accordance with specified standards. The problem boundaries in this research are tapioca flour, sago and fox glue with composition ratios of 95:5, 90:10 and 85:15. The pressing pressure used is 20, 25, and 30 Bar. The drying process uses sunlight, using a 750 ML air supply. The method used in this research begins with preparing the research stages, literature search to preparation of tools and materials to data processing analysis using ANOVA. Next, the quality of the briquettes is tested, namely hardness (kg/cm2) and density (gr/cm3). The results of testing the quality of coconut charcoal briquettes obtained an average hardness value for tapioca of 605 kg/cm2, sago 1,635 kg/cm2, and fox 45,124 kg/cm2, while the density values obtained were for tapioca 0.742 gr/cm3, sago 0.743 gr/cm3, and fox 0.728 gr/cm3
Rancang Bangun Console Game Portable 8bit Berbasis Esp-32
Full text linkThe rapid development of technology has greatly facilitated human activities and entertainment, with gaming serving as an effective means to reduce stress and enhance cognitive function. This study presents the development of a Portable 8Bit Game Console based on the ESP-32 microcontroller, which uses buttons for control and displays gameplay on a TFT LCD. The console is also equipped with a rechargeable battery. System testing yielded satisfactory results: the LCD displayed outputs with 100 % accuracy, the speaker’s average sound was 49,8 dB, buttons functioned optimally, battery voltage averaged 1.27 V, and the SD card data transfer speed was 30 MB/sec. The console operated according to specifications with no errors observed in the testing of five games
