Full text linkConsuming alcoholic beverages improperly or excessively has a very bad impact on the health of the human body, it can even cause accidents, fights, theft, murder and the risk of death. This research produces a tool that can detect alcohol content in liquid herbal using the MQ-3 sensor, DHT22 sensor, data logger to store test results data and the test results are grouped by means of manual calculations with Microsoft Excel and Matlab software simulations. The type of liquid herbal used is liquid herbal for rheumatic pain, gout, dizziness, colds and coughs. In each liquid herbal test, it takes 10 minutes/liquid herbal medicine and is repeated 6 times for each liquid herbal test. Based on the test that the higher the temperature affects the increase in the proportion of the alcohol content of the liquid herbal and the minimum temperature obtained is 30.8°C to 32.9°C. Microsoft excel calculations and matlab simulation software, clusters are divided into 3 according to the type of alcohol content group and the iteration stops at the 12th iteration with the objective function value = 0.00074 < error = 0.001.

Full text linkPT. Samihasa Kita is a glass product distributor company that was founded in 1989, which is located in the city of Semarang, Central Java, with sales area coverage in Central Java, D.I Yogyakarta, Jakarta, and Kalimantan. So far, PT Samihasa Kita has an erratic amount of demand for goods, as a result, sometimes the number of goods produced for sale with the goods purchased by consumers is not balanced. This resulted in PT Samihasa Kita not getting the maximum profit. Based on this problem, Fuzzy Tsukamoto logic was chosen to determine the optimal daily production amount. By using fuzzy logic can be determined the relative size of the production of goods. The Fuzzy Tsukamoto method can also be used to forecast sales in the coming month based on the amount of inventory. Thus the amount of production and demand for goods PT. Samihasa Kita is predictable and balances transactions. This research aims to be able to predict demand and procurement of goods that will have an impact on optimizing revenue at PT. Samihasa Kita
Design of Savonius Double-Stage Wind Turbine, Capacity 300W: Perancangan Turbin Angin tipe Savonius Double-Stage, Kapasitas 300W
Full text linkThe use of fossil energy sources is increasing along with the increasing need to make reserves of fossil energy sources dwindling. Without the discovery of new reserves, oil in Indonesia will run out in the next nine years, natural gas will run out in 22 years, and coal will run out in 65 years. According to ESDM data, with current technology, the electricity potential from renewable energy reaches 432 GW, or 7-8 times the current total installed generating capacity. Wind energy (wind) is one of the renewable energy potentials, and the most widely available among all energy sources. Therefore, to anticipate the depletion of energy reserves that we have and to take advantage of the existing energy potential, research is being carried out on designing wind turbines so that we can take advantage of the existing energy potential, and not only depend on fossil energy which is depleting, and the main goal is know how to design and get the appropriate size and design of the turbine. From the design results obtained the value of the rotor diameter is 442 mm, the height of the rotor is 884 mm, the blade height is 439 mm, the diameter of the end plates is 486.2 mm, and the diameter of the shaft is 18 mm. As well as from the simulation, the maximum shaft stress value is 30,794 N/m2, the maximum displacement is 0.313 x10-4 mm, the minimum safety factor is 3.028, and the strain value is 0.114 x10-6, where these results can be used as a reference for the manufacture of this wind turbine later

Design and Development of an Automatic Angklung Robot Based on Microcontroller: Rancang Bangun Robot Angklung Otomatis Berbasis Mikrokontroler
Full text linkThe angklung is a traditional musical instrument from West Java, Indonesia. It can be played both individually and in groups. Playing the angklung requires precision in terms of tempo, rhythm, pitch, and beats to ensure that the music aligns with the intended song and is enjoyable to listen to. Therefore, not everyone can play the angklung, as it demands skill to achieve the right tempo, pitch, rhythm, and beats. To address this issue, a solution was developed, which involved creating a system and device capable of playing the angklung automatically. In this research, a system was designed to move the angklung automatically, simulating a robot, and it is referred to as the "angklung robot." This angklung robot consists of a set of 16 notes, and the electrical components used include an Arduino Mega 2560 as the microcontroller, a 16-channel relay module, motor drivers, a micro SD module. To play a song, the device uses a score file that has been converted and stored on a micro SD card, adjusting the tempo to match the desired Beats Per Minute (BPM).Through several experiments, the angklung robot successfully played 10 pre-composed songs with a 100% accuracy rate. According to the opinions of 10 music enthusiasts who were surveyed, the level of accuracy in which the angklung robot played the songs was 90%.This innovation brings automation to the traditional art of playing the angklung, making it accessible to a wider audience and ensuring consistent and precise musical performances
