Abstract

Efforts to reduce the use of chemicals that pollute the environment need innovations to tackle the problem. One of them is to replace the chemicals contained in the battery by utilizing the waste of orange peel. Citrus skin has citric acid (C6H8O7) which can be used as an electrolyte solution as the contents of the battery because the citric acid can produce cations and anions that conduct electricity. This research aims to make the latest innovations so that the battery used now not only depends on synthetic chemicals, determining the pH value of the orange peel is suitable to serve as electrolyte-making material in Battery, look for the current strong value as well as the maximum voltage that can be generated from unused parts of the fruit as an electrolyte in the battery, understand the principle of bio-battery work by utilizing the Orange peel as a material maker Its electrolyte, utilizing the abundant natural resources as well as possible, reduces the environmental pollution effect due to the content of the battery content made from synthetic chemicals. The research method is done by sorting the orange peel then smoothed, after it was given the addition of H2O water, the mixing is left evenly mixed, then separate the water with the orange skin mixed. After that, the water is mixed with wood charcoal and dried until the water is 50% reduced, so it is ready to be used as an electrolyte on the battery. The results showed that the orange Peel had a pH of 3.8 and had acidic properties so that it could be used as an electrolyte on batteries. The electrolyte produced by the orange Peel produces a voltage of 0.81 volts and has a strong current of 0.049 mA with a resistor load mounting of 4.7 KΩ. Battery capacity with a length of 4 cm, width of 2 cm and a height of 9 cm to produce a battery capacity that can be utilized by 4.752 mAH with a voltage of 0.8 Volt.

Abstract

Ketika tindak kejahatan yang semakin meningkat, terutama dalam kasus pencurian kendaraan bermotor. Solusi yang dilakukan oleh pemilik kendaraan bermotor biasanya hanya menggunakan kunci ganda. Pencuri dapat membuat duplikat kunci kendaraan sehingga pencuri dengan santai bisa untuk mengambilnya.Dalam perkembangan teknologi saat ini, teknologi telepon seluler telah berubah menjadi perangkat multifungsi. Dengan memanfaatkan SMS(Short Message Service) dapat mengontrol sistem keamanan kendaraan bermotor menggunakan Mikrokontroler AT-Mega 328, serta modul GPS SIMCOM SIM908 untuk bisa mengetahui lokasi kendaraan tersebut berada. Dengan teknologi yang semakin canggih sekarang diharapkan kejahatan, terutama pencurian kendaraan dapat dikurangi. Dengan sistem keamanan kendaraan bermotor menggunakan GPS berbasis media SMS dapat memberikan keamanan lebih kepada pemilik kendaraan, karena pemilik kendaraan dapat mengetehui keberadaan kendaraanya jika terjadi suatu pencurian

Abstract

Dalam penelitian ini dilakukan proses perancangan dan implementasi alat ukur tegangan, arus dan frekuensi listrik arus bolak-balik satu fasa. Dalam proses perancangan instrumen ukur listrik bukanlah hal yang mudah, karena harus memperhatikan faktor kesalahan alat, serta efisiensi penggunakan teknologi instrumentasi elektronika yang digunakan. Pada alat ukur yang dibuat dalam pengukuran tegangan dan arus dilakukan dengan proses transformasi besaran yang di ukur menjadoi bentuk besaran tegangan dan arus yang lebih rendah menggunakan tranformator penurun tegangan dan OTTO transformator arus sehingga sinyal keluarannya dapat diproses pada perangkat pemroses data menggunakan analog to Digital Converter (ADC) dengan lebar data 10 bit pada mikrokontroler AVR Atmega8535. Untuk pengukuran frekuensi dilakukan dengan menghitung banyaknya zero crossing per satuan waktu dengan menggunakan fasilitas Interupsi Eksternal pada mikrokontroler. Untuk perangkat penampilan data hasil pengukuran digunakan perangkat Liquid Crystal Display (LCD) dan ditampilkan dalam program Graphic user Interface (GUI) pada personal computer berbasis Microsof Visual C# 2008 Express Edition. Dalam pengujiannya alat pengukur Tegangan, Arus dan Frekuensi listrik arus bolak-balik satu fasa ini terdapat kesalahan rata-rata pengukuran (error pengukuran) pada pengukuran tegangan sebesar 0.45%, pengukuran frekuensi sebesar 0,09%, dan pengukuran arus sebesar 2%.

Abstract

The progress of a city can be seen in its lighting system, such as billboard lights, street lights and traffic control systems. Lighting the lights on each street requires a lot of electrical energy because there are quite a number of these lights and they light up for a long time. The street lighting system will beautify buildings, shops, hotels and offices at night and create a sense of security for the community. The purpose of this study is to utilize a street light lighting control system to adjust the intensity of street lighting according to busy road conditions. This research method was carried out by observing the amount of energy used by conventional street lights and observing the energy absorbed by street lights with controls according to the needs of street lighting intensity. In this study, the energy entering the lamp is regulated from 18.00 - 22.00 by 100%, at 22.01 - 24.00 by 55%, at 00.01 - 04.00 by 30% and at 04.01 - 05.59 by 100% so that it can save energy by 42, 55% compared to 50 watt COB lamps which are supplied 100% from 18.00 - 05.59. Energy savings of 42.55% if implemented within one month can save around 9.66 kwh and if implemented within one year can save 115.92 kw
