Abstract

At present the use of wind energy in Indonesia is still relatively low, but has enormous potential. One reason is because the average wind speed in the territory of Indonesia is classified as low wind speed, which ranges from 3 m / s to 5 m / s making it difficult to produce electrical energy on a large scale. However, the wind potential in Indonesia is available almost all year long, making it possible to develop small-scale power generation systems. Innovations in modifying windmills need to be developed so that in conditions of low wind speeds can produce electrical energy. In this research, a prototype was developed by designing a vertical axis windmill power plant model Savonius using a permanent magnet generator, which can produce optimal electrical energy by utilizing relatively low wind speeds.From the generator test it was found that with a rotor rotation of 50 rpm up to 500 rpm can produce an electrical voltage of 0.02V to 10V and an electric current of 0.60A to 4.53A.

Abstract

Dalam penggunaan motor listrik sebagai penggerak mesin-mesin produksi pada suatu industri diperlukan suatu sistem pengaman proteksi yang hares dipasang pada motor tersebut untuk mengurangi kerugian-kerugian yang ditimbulkan aldbat gangguan yang mungkin terjadi. Hal ini diperlukan terutama pada motor-motor listrik yang panting/ vital dan mempunyai kapasitas besar sehingga motor yang digunakan benar-benar mempunyai kehandalan dalam pelayanannya, dimana untuk menunjang proses produksi maka dalam pengoperasian motor listrik ini hams mempunyai keandalan yang tinggi untuk menjaga kestabilan dan kontinuitasnya, karena masalah kestabilan dan kontinuitas sangat berpengaruh terhadap suatu proses produksi. Tujuan penelitian ini adalah membuat slat untuk mengamankan peralatan listrik yang mana peralatan tersebut dilihat dan' harga sangat mahal seperti motor listrik inverter. Alat ini dipasang pada motor tersebut dan kontrolnya dihubungkan secara seri dengan kontrol rangkaian lain seperti contactor dan thermal overload relay. Metode penelitian yang digunakan adalah metode Engineering Research yang dilaksanakan melalui empat tahap yaitu Define (perumusan masalah), Design (perancangan sistem), Develop (pengembangan atau implementasi rancangan dan uji coba) dan Disseminate (distribusi dalam lingkup terbatas). Melalui perhitungan secara teoritis dan uji coba, rangkaian pengaman/ proteksi motor listrik 3 fasa, 350 volt, 50 Hz hasilnya lebih akurat.

Abstract

Ant Colony Algorithm (ACA) is an optimization algorithm was inspired by ant behavior when searching for the shortest distance from the food center. In this study, ACA is used for power plants with a fuel cost fitness function. ACA can search destinations faster than conventional methods such as Lagrange. In this study ACA used the optimal power flow of six power plants in the Java Bali 500 KV system, the optimization results reduced fuel costs by 23% and Lagrange 17.4% compared to real conditions.

Abstract

To turn on and turn off lights in the mosque area in general still use a manual system that is to turn off and turn on the lights using a switch located on the wall. Therefore, currently a system that has been designed automatically is needed to control the light of life and the outages of lights based on a predetermined time and based on the detection of human presence, so that the lights will turn on and off automatically at the set time according to needs, namely using Real Time Clock (RTC) and Passive Infrared Receiver (PIR) sensors. The results obtainedin the form of a light controller system in the area of the mosque using DS3231 RTC and Arduino Nano At mega 328P PIR Sensor. At 3:00 and 17:00 the condition of the lights is on and at 05:30 and 21:00 the lights are off. For the measurement of PIR sensor detection distance, the distance of 5 meters of the PIR sensor can still detect the presence of human movements, after 5 meters or even 6 meters of the PIR sensor cannot detect human movement. So that within a distance of 6 meters or more, the toilet lights cannot turn on automatically or turn off.

Abstract

The automatic fish grill is a tool that is very helpful for food vendors who are processed in a roasting manner. For now, conventional automatic grills that are already on the market have very expensive prices so that many traders still use manual fish grills which are less efficient in the process of doing them. The purpose of making this automatic fish grill design is to help human work to save more time and energy. The automatic fish roasting box is designed with heat absorbers in each layer, equipped with two racks, each measuring 50cm and also equipped with 2 250 watt heaters. From the test results using different types of carp with different weights, it shows that the automatic fish grill works well and gets a 100% percentage result with evenly cooked fish. The economical level of automatic fish grill has a good value, the whole design of automatic fish grill uses good quality materials and materials. For now, automatic roasters on the market have very expensive prices, this difference in price has made many traders not take full advantage of the technology. Because of this problem, researchers created an automatic fish grill based on a temperature controller, which is targeted at an inexpensive price, but can still be used safely and with maximum results. Thus, using a temperature controller-based automatic fish grill design can help simplify work to make it more efficient and safer.

Abstract

Increasing energy demand, depleting fossil fuel reserves, and environmental concerns have put renewable energy sources in the spotlight in Indonesia. Wind energy in particular, which has received a lot of attention because it is inexhaustible and friendly to the environment. The main problem of the two generating systems is not continuously available. Wind turbines are the main medium used to convert wind energy into electrical energy. A good wind turbine design will determine the performance of a wind power plant (PLTB). This tool is to control the electric power generated from the wind generator, the electric power generated from the generator will be measured the current and voltage. The way the tool works when the generator wheel rotates, the generator will produce electrical power which has been connected to the charger controller before the electric power is stored in the battery. The use of electric power from the battery will be converted using an inverter to convert the DC current to AC. This research was conducted on wind turbine generators in the use of coastal street lighting as objects to generate electric power in order to reduce the need for PLN electricity.

Abstract

Honey is a natural sweet substance produced by bees with nectar flower ingredients containing various nutrients such as carbohydrates, proteins, amino acids, vitamins, minerals, plant pigments and aromatic components. Honey consists of water (17%), fructose (38.2%), glucose (31.3%), other disaccharides (5%), melezitose (<0.1%), erlose (0.8%) , other oligasakarida (3.6%), minerals (0.2%), amino acids (0.3%). It also contains anti-microbial substances, which can prevent some disease on human. Because it has a high economic value and contains unique substances, honey is often falsified. Honey can be faked in various ways by mixing natural artificial sweetener components or by giving the sugar (sucrose) into the honey, so it is dangerous if given to infants or people suffering from diabetes mellitus. The design of this research used spectrofotometer methode and pattern recognition algorithm (machine learning) system for classifying honey quality. It is based on honey having a chromophore group responsible for absorbance, electronic transition and color giver. We can also knowing the type of honey by using pattern recognition algorithm support vector machine.In this research is used three types of honey to using a spectrophotometer at a wavelength of 500 nm, the absorbance obtained in randu honey type of 0.523-0.654, coffee honey for 0.735-0.824, and rubber honey by 0.947-1.043.
