Abstract

LPG (Liquid Petroleum Gas) has been used in everyday life. But if there is leakage it will cause poisoning and explosion. Underlying this, the authors made research on monitoring and control of air quality. The purpose of this study is to make a device that can detect earlier leakage of LPG. This device can detect excess levels of carbon monoxide in the air. Even more, it can avoid the danger of fire and poisoning. The research method used descriptive analysis method and quantitative analysis method. Measurements and testing with accurate reference measuring instruments. Based on testing and analysis, the device can work well with an average percentage error of 1.92% for CO gasmeasurement and 3.1% for LPG gas measurement. Increasing gas content in each sensor is proportional of increasing in the sensor output voltage. Some of the factors that cause errors were the differences of sensor sensitivity and environmental conditions where the sample measured.

Abstract

TDS meter is a measure of the conductivity of solutes in liquids, this tool is often used as an important component in determining water quality before use. There are still several components to be examined beside TDS, one of which is temperature. Temperature is an important component to measure the feasibility of water. Temperature measuring devices can be used to find out how much the temperature of the liquid being measured. The TDS meter that is already in the general public can only be used to find out the TDS. So, if people want to measure other components such as temperature, a thermometer is needed to measure it, of course this becomes inefficient and requires a higher cost because if you want to measure other components, the public must buy another measuring instrument. Therefore, on this occasion to make measurement tools become more efficient, the writer will design a measuring instrument that can be used to measure 2 components at once, namely a TDS meter and a thermometer designed in one device. TDS meter uses a conductivity sensor and a thermometer uses a DS18B20 waterproof temperature sensor.

Abstract

Every human being has a feeling of saturation in carrying out his daily activities. There are many ways you can do to get rid of boredom, one of which is by doing hobbies that we like. Currently there are many hobbies that can be done, one of which is a hobby of decorating an aquarium (Aquascape) by using stones, wood, sand and using water plants. Which is starting to be of interest to various circles of society. For Aquascape owners, sometimes their daily activities are busy. In fact, these other activities can take up to days. The solution to the problem of fan negligence when maintaining the Aquascape is to build an aquarium system that can adjust the lighting periodically as needed, stabilizing the water temperature in the aquarium

Abstract

Poor waste management and lack of public awareness of environmental hygiene, especially if waste is disposed of in the local trash can, causes garbage to accumulate and emit bad odors which can be a source of disease transmission. The lack of information technology for waste management by janitors can cause slow waste disposal. Based on these problems, it is necessary to equip an automatic trash can with a monitoring function in real time. Added the IOT (Internet of Things) function, which can provide initial information indicating that the trash can is full and can be quickly picked up by the garbage collector. The smart trash can prototype uses an ESP 32 microcontroller as a system control. Servo to control the trash can cover. The output of DF Player is in the form of thanks to people who throw garbage in its place. Ultrasonic sensors can detect human presence and waste volume and send monitoring results in real time as well as notifications to the blynk application as a notification if the trash can is full.

Abstract

Development of Metaheuristic Algorithm in engineering problems grows really fast. This algorithm is commonly used in optimization problems. One of the metaheuristic algorithms is called Firefly Algorithm (FA). Firefly Algorithm is a nature-inspired algorithm that is derived from the characteristic of fireflies. Firefly Algorithm can be used to solve optimal power flow (OPF) problem in power system. To get the best performance, firefly algorithm can be combined with fuzzy logic. This research presents the application of hybrid fuzzy logic and firefly algorithm to solve optimal power flow. The simulation is done using the MATLAB environment. The simulations show that by using the fuzzy-firefly algorithm, the power losses, as well as the total cost, can be reduced significantly.

Abstract

This paper introduces two advantages of a fuzzy logic controller for the first is stability voltage and the second is maximum energy extraction for fixed speed wind power generation systems. Maximum energy extraction is determined by thetip speedratio (TSR) and the power factor of a wind turbine in order to capture the maximum efficiency and control the speed of turbine in order to control voltage stability.While the TSRand power factor were taken as output variables we propose control the tip speed of generator in surrounding the value of maximum TSR. The proposedmodel produced fuzzy logic controller can keep the voltage stability at maximum TSR and nearest. The results indicate that we can do two task (power max extraction and stability voltage) in one design.

Abstract

Dalam pengoperasian sisitem tenaga listrik harus selalu diusahakan agar daya yang dibangkitkan sama dengan permintaan daya system. Pengaturan pembangkitan untuk memenuhi permintaan tenaga listrik, disusun menurut prioritas, yaitu pembangkit dengan biaya bahan bakar paling murah ditempatkan untuk mendukung beban dasar, sedangkan pembangkit yang tidak efektif digunakan untuk mendukung waktu beban puncak.Pengaturan penggunaan tenaga listrik adalah program pengaturan waktu dan besaran pemakaian tenaga listrik agar diperoleh pemakaian yang efisien dan hemat. Pengaturan dilakukan dengan menurunkan atau menghemat tenaga listrik, pemasangan beban puncak dan pengalihan beban dari waktu beban puncak (WBP) ke luar waktu beban puncak (LWBP), sehingga suplai pembangkit yang tidak efisien bahan bakarnya dapat berkurang. Metoda pengaturan pemakaian tenaga listrik dari sisi pengguna adalah high efficiency lighting, improved refrigerators, improved air conditioning, improved motors, penggunaan tenaga listrik pada luar waktu beban puncak, energy manajement audits, efficient new construction. Pelaksanaan metoda tersebut perlu penghematan sosialisasi ke konsumen tenaga listrik. Penghematan yang diperoleh dapat digunakan untuk menunda rencana pembangunan system tenaga listrikyang disebabkan pertumbuhan permintaan tenaga listrik, pemenuhan permintaan calon pelanggan tenaga listrik dan menurunkan pembayaran rekening listrik.
