Abstract

Global warming, climate changes mostly associates with solar-renewable energy; however wind-energy potential has no detail reports in Indonesia. This study aims to mapping of characteristics and potential of wind as renewable-energy from long-term (1997-2009) satellite remote-sensing. Wind direction (WD), speed (WS) derives from microwave/ scatterometer sensor on satellite operational years as follows: ADEOS (1997), DMSP (1998-1999), AMI (1997-1999), QuikSCAT (1999- 2009). Data processed into 0.25o grid, monthly temporal resolution. The regional characteristics of WD/WS, seasonal and zonal-longitudinal reveals by statistic. Electrical energy derives from kinetic energy of turbine-blades per-unit time. Energy conversion uses power-curves and technical parameters of 1.50 and 3.40 MW (GE 1.5s, 3.4-137 models) onshore installations with 25km2 per point, 15% availability area. Result shows WS has low characteristics in Indonesian-waters (<3.7ms-1). WS has high at north-south Java-Sumatra, Banda waters (<6.9ms-1). The zonal-seasonal wind variability of WD, WS stables at equator. Increases of degree-zonal (>5deg), wind curve follows north-south hemisphere characteristics and crosses in April, October. The north-west, south-east monsoon shows clearly only on north-western of Java-Sumatra waters. WS has range of 0-25.20ms-1, average 6.64ms-1 with Std. 1.64ms-1. With these WS, generation of electrical energy has range from 104.0 to 2230.5 kWh per-point installation grid.

Abstract

Converter kits are equipment used to translate fuel oil (CNG) into gas fuel (CNG) in convertible vehicles. The use of a converter kit with CNG liquefied petroleum gas (LPG) will be used to optimize engine performance while driving, but its use is not yet known among the public because it is not affordable and there is no transition from fuel to consumed gas. Therefore, it is necessary to design a simple converter kit, affordable by the community, and can be supported on two different fuels. This study redesigned the manual converter kit with a research focus on aluminum gas mixer components with variations in the number of intake mixers (1, 2, and 3) and added mixing zones in the mixer area, using 110 cc single cylinder motorized engine with carburetor fuel system with a variation of 1500-9000 rpm. Engine performance testing is done using a chassis dynamometer. The use of LPG fuel in various types of input mixers is able to increase torque and power on the engine. Engine performance test data shows that the best torque value on the use of LPG materials in input mixer 1, 2, and 3 holes respectively are 17.44 Nm, 16.77 Nm and 11.71 Nm, while for gasoline fuel is 16 Meanwhile, the value of power in the use of LPG fuel with the input of mixer 1, 2 and 3 holes is capable of producing maximum power respectively 7.1 Hp, 7.4 Hp and 7.3 Hp, while for gasoline fuel at 7.7 Hp. The use of LPG fuel with the number of 1 hole mixer input is the best variation compared to gasoline fuel and the number of mixer inputs in the other variations.

Abstract

The availability of telecommunication infrastructure affects the development of an area, especially areas that have the potential for tourism and agricultural products such as Tenjolaya Village. The development of RT RW net as internet network infrastructure using Wi-Fi technology can be a supporting sector for the economic development of the village. Network deployment is carried out in three stages: preparation, construction and measurement. In the preparation stage, the number of users is calculated and a survey of the installation location is carried out. Furthermore, network development is carried out based on the network architecture that has been designed with CPE totaling four points. In the final stage, four parameters are measured to check the network conditions. The parameters are throughput, signal strength, CCQ, and SNR. From the measurement results, the measured throughput at the access point has a value range of 17 to 30 dBm. The measured Tx signal strength has a value of -75 to -39 dBm while the Rx signal strength is between -72 to -37 dBm. The CCQ value is between 76 and 100%. The measured SNR parameter has a value of 38 to 77 dBm.

Abstract

Objective this research is to automatically schedule student final assignments using genetic algorithms in the Automation Engineering Technology Study Program of the Manufacturing Polytechnic in Bandung. Genetic Algorithm (GA) is a heuristic method or a method of finding optimal values using the principles of evolution. GA is used as a solution search algorithm in this research. The solution was implemented into a program that can create a schedule automatically based on the limitations set by program users. Scheduling parameters that are focused on in this study are duplication or clash issues and category suitability between the final project and examiners. Based on these parameters the program can produce the optimal schedule with varying success rates depending on the ratio between the number of trial examiners and the number of examiners needed at one time, where a ratio above 2: 1 result in success above 90% for duplication cases, and the ratio is above 1.5: 1 for category conformance cases.

Abstract

Virus Corona (COVID-19) adalah virus yang sedang menjadi pandemi di dunia. Di Indonesia, tercatat lebih dari 700 ribu kasus positif dengan lebih dari 21 ribu orang meninggal akibat infeksi virus corona. Penanganan pasien COVID-19 tentu perlu menjadi perhatian untuk mengurangi penyebaran virus tersebut.  Upaya yang bisa dilakukan adalah meminimalkan kontak kecuali memang sangat mendesak dan darurat. Penggunaan robot sebagai pelayan medis menjadi alternatif untuk mengurangi kontak dengan pasien yang dikarantina. Robot pelayan medis dapat digunakan untuk melaksanakan pelayanan rutin seperti mengantar makanan, obat atau keperluan lain yang sifatnya tidak mendesak. Dalam penelitian ini, Robot yang telah dirancang mampu dikendalikan menggunakan gawai berbasis Android yang dikoneksikan menggunakan jaringan tanpa kabel. Robot yang telah dirancang juga memiliki fitur untuk video call sebagai sarana konsultasi jarak jauh dengan tenaga kesehatan. Selain itu, Robot tersebut juga mampu membawa beban hingga 40 kilogram.

Abstract

The availability of crucible furnaces is still limited, so the price in the market is relatively expensive, even though this tool is very important, especially in educational institutions as media for the practice of metal casting. The purpose of this study is to design, build and test the work of a crucible furnace that utilizes used cylinders by using LPG gas heat sources. The design of the furnace uses the autodesk inventor application while the manufacture uses machine tools. Technical data from this crucible furnace is that the body is made from used gas cylinders with an outer diameter of 280 mm, an inner diameter of 140 mm and a height of 490 mm. In the combustion chamber installed a 25.4 mm diameter gas pipeline with a length of 370.5 mm and an air channel diameter of 50.8 mm with a length of 367 mm. Kowi is made of steel with a 110 mm dimension and a height of 280 mm. The results of trials with aluminum smelting show that the crucible furnace is capable of melting 5 kg aluminum for 60 minutes with fuel consumption of 3 kg gas. The maximum temperature that can be reached 1367 oC for 15 minutes by a crucible furnace.Keywords: design, manufacture, furnace trials

Abstract

Superhost Airbnb is an experienced host and provides excellent service to its customers. Superhost has features that can increase the number of bookings and revenue. SuperHost profile is one thing that can be used as a reference for other hosts to improve the quality of service. In this study, an analysis of exploration and visualization of Airbnb hosts' data in the city of Amsterdam and the city of Madrid to find out the profile of superhost from the aspect of price and consumer reviews. The city of Amsterdam and the city of Madrid are chosen because the two cities are the leading destinations for tourists in Europe. The study was conducted using a machine learning approach that has four work steps, namely understanding business processes, data retrieval, data processing, and exploratory analysis and data visualization. The tools used in this study are Jupyter Notebook with the Python programming language. The results obtained from this study are superhost in Madrid, mostly offering rental prices in the price range of $60 - $80. They get the highest reviews from customers based on cleanliness, communication, and check-in. As for Amsterdam, the superhost offers the most rental prices in the price range above $ 140. Superhosts in this price range gets the most reviews from customers in all review groups.
