Abstract

Abstract - Solar energy is one of the alternative energy sources which can be used as electrical energy. As the effect of earth rotation and revolution, it had not been optimized maximally yet. The rotation of earth causes the sun moves from east to west every day, and the revolution of earth causes the sun move from north to south every year. These phenomenons cause the different intensity of sun light in every earth surface. To optimize the sun light, the design and realization of solar tracker is very important. The solar tracker has to be able to track the position of the sun and move the solar cell to face the sun light. The solar tracker can move in two axis with moving type of rotate and tilt, so  it works optimally every time. This solar tracker is designed by using photo diode as light sensor and servo motor as actuator. The system uses ATMega8535 as control unit which able to process signal from the sensor and resulted Pulse Width Modulation to control servo motor moving. The testing showed this solar tracker capable to raise the average power to 0.676 watt and the eficiency to 36,216%. The error of tracking is 90 at heavy cloud. Key Word: Light Sensor, Servo Motor, Solar Tracker

Abstract

AbstractIndonesia is one of the areas prone to disasters, especially floods. The impact of flooding can be reduced if the community is better prepared to face the coming flood. Therefore we need an early flood detection tool that can give a signal to the community through early warning so that the community can be more alert in facing flood disastersThe results of this design make two systems, the main control system and the receiving system. The main control system consists of an ultrasonic sensor, SIM800L module and NodeMCU Wi-Fi module. The receiving system consists of a SIM800L module and a siren. The results showed that the ultrasonic sensor used has a good level of accuracy with an error value <1%. The results of SMS testing have a delay until the SMS to the recipient is around 5-10 seconds. The test results also show that 4G network technology has 100% delivery accuracy and 3-4 seconds delivery delay per data. The final result shows thatthe system is able to work as desired and is able to be well connected to the web server.Keyword:Flood Disasters, SIM800L, Ultrasonic sensor, Web Servers, SMS

Abstract

Point of Sales System (POS System) is a recent popular application that able to overcome the daily business operational problems of SMEs, because it provides information on thetypes of goods, prices, and inventories. This activity introduces POS and training partnersto use the application. These activities are successfully implemented a method that isspecifically designed for the layman who do not understand the science of accounting. Themethod is called puzzle drilling method. This method proved to be effective to change themindset quickly. At first all the partners prepare an income statement with the concept ofmoney going out and money coming, but with this method partners quickly realized theirmisunderstanding and ignorance about the income statement. Generally this activity hasits own benefit for the SMEs owner.Keywords: Point of Sales System, Puzzle Drilling Method, Income Statement

Abstract

Cukup tingginya tingkat fatalitas kecelakaan lalulintas (laka lantas) di Bengkulu hingga saat ini disinyalir disebabkan oleh ketidakpatuhan terhadap aturan dan pengabaian prinsip keselamatan saat berkendara. Kondisi ini tentu menjadi perhatian khusus Sat Lantas Polres Bengkulu. Petugas berkomitmen untuk tegas menindak tilang terhadap pelanggaran lalu lintas oleh pelajar. Kecelakaan jalan raya, termasuk tabrakan antar kendaraan banyak terjadi di simpang yang banyak dilalui oleh kendaraan untuk menuju ke arah yang menjadi tujuan. Apabila kendaraan dalam keadaan mengebut dan tidak mengurangi kecepatan, maka probabilitas terjadinya kecelakaan akan semakin tinggi. Hal ini didukung juga oleh tidak tepatnya penempatan lampu lalu lintas di persimpangan dan jalan yang memiliki roundabout (bundaran).Penelitian telah menunjukkan bahwa bundaran lebih aman daripada tanda berhenti tradisional atau persimpangan yang dikendalikan sinyal. Roundabout mengurangi kecelakaan akibat kecelakaan sebesar 75 persen di persimpangan tempat tanda berhenti atau sinyal sebelumnya digunakan untuk kontrol lalu lintas, menurut sebuah studi oleh Lembaga Asuransi untuk Keselamatan Jalan Raya (IIHS). Dengan adanya pengabdian ini, mahasiswa pengguna jalan raya akan semakin waspada dan memahami tentang penggunaan roundabout yang baik dan benar.
