Abstract

Krisis energi khususnya energi listrik yang melanda Indonesia dan negara di dunia telah memaksa berbagai pihak untuk mencari solusi dalam mengatasi persoalan ini. Banyak sekali penelitian yang telah dilakukan untuk mencari sumber energi alternatif selain dari minyak bumi, batubara dan gas alam. Sumber energi tersebut menyebabkan pencemaran udara, air dan tanah serta menghasilkan gas rumah kaca (green house gas) yang berperan dalam pemanasan global. Oleh sebab itu, dilakukan penelitian di berbagai energi alternatif dan terbarukan (go green) , diantaranya energi medan magnet bumi, biomassa ,energi panas bumi, energi surya, energi air, energi angin dan energi samudera. Disini penulis tertarik untuk mengkaji energi magnet bumi khususnya energi medan magnet bumi sebagai energi alternative di masa depan. Kata Kunci: Bahan bakar fosil , Greenhouse gas, Pemanasan global ,Energi terbarukan ,Medan magnet bumi.

Abstract

In the 4.0 era, walking aids for the visually impaired are needed, especially when the user is indoors and outdoors. There are already many tools created, one of which the author wants to make is a wristband. Components include: Ultrasonic Sensor HC-SR04, Arduino Nano, Servo SG90 Motor, and Buzzer. The stages in this study are designing hardware, designing programs, and implementing and testing tools. The testing carried out on this tool is to read the results of objects with distances of 80cm, 90cm, 100cm, 110cm and 120cm. Not only did it test the distance, it also tested the rotation angle performed by the servo motor to drive ultrasonic sensors by 0o,60o,and 120o. It aims to be able to detect in any direction. The results of this tool test have a repeatability rate of 98%, as well as a 97.33% success rate for detecting objects.

Abstract

Patrol that is distributed to the public must meet the requirement for the quality, quantity and continuity. Pertamina as one of the companies that is responsible for the distribution of patrol to the public through gas stations and must have competent management and services. However, problems arise in the community and even companies in controlling fuel consumption and queues for sales services at gas stations. One solution is to use a station that is connected to smartphone wirelessly and a cashless. Through the "Smart Fuel Station and Management System Based on Arduino and Internet Of Things", that will be able to help the community and companies in controlling their fuel consumtion and making savings. This monitoring tool uses the Arduino ESP8266 which is combined with Internet of Things (IoT) Technology which is displayed on the LCD and the Internet Web. Customers can purchase the patrol at gas stations independently, by connecting the smartphone application with the gas station wireless and purchase and make payments through the application. By having top up the balance on the application to be able to make purchases as needed and the balance will continue to decrease according to usage. The fuel filling station will issue it according to the nominal or the number of liters we choose in the application. Customers can view detailed fuel purchase for place, date, time, amount and total balance.
PEMANFAATAN LIMBAH TONGKOL JAGUNG MANIS (ZEA MAYS L SACCHARATA) SEBAGAI BAHAN BIOPLASTIK DENGAN PENAMBAHAN ZnO DAN GLISEROL Tri Kurniawati, Cici; Sutrisno, Joko; Adi Walujo, Djoko; Prijo Sembodo, Budi

Abstract

Bioplastik adalah plastik atau polimer yang secara alamiah dapat dengan mudah terdegradasi baik terurai oleh mikroorganisme sehingga dapat menjadi alternatif pengganti plastik komersial. Penelitian ini bertujuan untuk memanfaatkan limbah tongkol jagung manis (Zea Mays L Saccharata) sebagai bahan dasar pembuatan bioplastik dengan penambahan variasi penguat ZnO dan gliserol sebagai platicizer. Penelitian ini dilakukan dalam beberapa tahap, yaitu preparasi bahan, pembuatan pulp, pembuatan bioplastik dengan variasi konsentrasi ZnO (3%, 6%, 9%) dan gliserol (25%, 30%, 35%), serta karakteristik bioplastik. Bioplastik yang dihasilkan dari berbagai perbandingan ZnO dan gliserol memiliki karakterisitik yang berbeda-beda. Analisis gugus fungsi, tidak ditemukan adanya gugus fungsi baru dalam bioplastik dibandingkan terhadap gugus fungsi yang ada pada bahan pembentuknya. Hasil analisis sifat mekanik bioplastik menunjukkan bahwa semakin besar konsentrasi ZnO maka nilai kuat tarik bioplastik akan meningkat sedangkan nilai elongasi bioplastik akan menurun. Semakin besar konsentrasi gliserol maka nilai elongasi bioplastik akan meningkat sedangkan nilai kuat tarik bioplastik akan menurun. Bioplastik dengan konsentrasi 35% gliserol mempunyai tingkat presentase penurunan degradibilitas lebih tinggi dibandingkan dengan konsentrasi gliserol 25% dan 30%. Dari hasil penelitian ini dapat disimpulkan bahwa komposisi paling baik untuk pembuatan bioplastik berbahan dasar limbah tongkol jagung manis dengan penambahan penguat ZnO dan plasticizer gliserol adalah 9% ZnO dan 30% gliserol.
