Abstract

Abstrak Kasus pencurian sepeda motor semakin meningkat akhir – akhir ini. Namun tingkat pengukapan kasus yang berhasil dilakukan oleh pihak kepolisian tergolong minim. Salah satu penyebabnya adalah sulitnya tim penyelidik untuk mecari lokasi kendaraan yang dicuri tersebut berada. Salah satu solusi yang bisa dilakukan adalah dengan memasang pelacak pada sepeda motor kita. Dengan semakin berkembangnya teknologi, perangkat GPS dapat kita gunakan sebagai alat untuk melacak kendaraan kita dari tindak pidana pencurian. Dengan mengaplikasikan GPS pada sepeda motor, kita bisa mengetahui posisi kendaraan tersebut, di belahan bumi manapun motor itu berada. Kemudian ditambah perangkat GSM, posisi kendaraan tersebut dapat dikirimkan menggunakan GPRS. Sehingga jika suatu ketika motor tersebut hilang, kita dapat dengan mudah untuk menemukannya kembali. Pada tugas akhir ini akan dibahas perancangan alat pelacak menggunakan modul GPS NEO 6M dan pengaman menggunakan modul GSM SIM900 untuk kendaraan sepeda motor dengan menggunakan mikrokontroler ATMEGA644PA sebagai pengendalinya. Hasil penelitian ini menyimpulkan modul GPS yang digunakan memiliki selisih sekitar 0,23”-0,25” untuk koordinat lintang dan 0,02”-0,05” untuk koordinat bujur dan alat yang dirancang dapat bekerja sesuai dengan yang diinginkan meskipun terdapat sedikit perbedaan pada posisi awal pelacakan kendaraan. Kata Kunci: GPS, GSM, ATMEGA644, keamanan, Sepeda Motor.  Abstract Cases of motorcycle theft has increased lately. But the level of completion successful cases done by the police relatively minimal. One reason is the difficulty a team of investigators to look for the location of the stolen vehicle is located. One of the possible solutions is to install a tracker on our motorcycles. With the development of technology, the GPS device can be used as a tool to track our vehicles from criminal act of theft. By applying the GPS on a motorcycle, we can know the position of the vehicle, anywhere in the world that the motor be. Then added a GSM device, the position of the vehicle can be sent using GPRS. So if an when the motor is gone, we can easily to find it again. This final project will discuss the design of a GPS tracking device using NEO module 6M and safety devices using SIM900 GSM module for motorcycle by using ATMEGA644PA microcontroller as controller.

Abstract

In this study, the effect of adding latitude stone as a substitute for cement on the compressive strength of mortar in the manufacture of construction materials was analyzed to produce building materials with better quality. One of the ingredients in the manufacture of mortar is cement with the main formers is calcium. The addition of laterstone is an effort to increase the calcium element needed in the pozzolanic reaction when mixed with SIO2 in laterstone. The purpose of this study was to increase the compressive strength of mortar by adding laterstone as a substitute for cement. The research method used is a quantitative experimental method with data collection from laboratory research and using laterstone powder that passes the 200 sieve, in mortar mixes with percentage variations of 0%, 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9% and 10%. The proportion of mortar mixture in this study used a ratio of 1: 3 (Cement: Sand) with a cement water factor (FAS) of 0.5 and was carried out using a compressive strength tool on a 5cm x 5cm x 5cm cube-shaped mortar at a time (age) of 7, 14, 21 and 28 days. Various tests were conducted on the materials and specimens to analyze the compressive strength and mass density of the mortar. The results of this study showed that the mortar achieved the highest compressive strength of 20.33 MPa with 3% laterstone mix variation at the age of 28 days. Mortar with more than 3% laterstone mixture variation will result in a decrease in compressive strength, thus reducing the compressive strength. This can be one solution to reduce the use of cement while reducing the exploitation of limestone mountains in Indonesia.

Abstract

Forensics has become an essential part of the disclosure of criminal evidence. A bioinformatics approach in the form of DNA forensics and digital forensics can be a good combination in disclosing digital-based criminal evidence. This study explains how the role of bioinformatics through the digital approach can be a means of forming new approaches in integration with digital forensics, called cyber-bioinformatics. Despite many hopes and challenges ahead, it does not rule out the possibility of criminal cases related to the privacy of human genomic data, so it proposes a new hypothesis, “cyber-bioinformatics.” The role of cyber-bioinformatics is very central in this regard.

ABSTRACTFuel Oil (BBM) is one of the fuels that have been used to drive most of vehicles such as motorcycles. The authors did the research on motorcycles using electrical energy to be more environmentally friendly. Experiments were done by using the direct test method and analyzing the obtained data to determine how much power was released and how much battery capacity was used to drive an electric motorcycle with variations of the driver's weight as much 60 Kg, 90 Kg, and 125 Kg and speed variations such as 10 Km/Hour, 20 Km/Hour, 30 Km/Hour, and 38 Km/Hour. The experimental results shows that the greater the weight and the speed of the motorcycle, the greater the power and capacity of the battery, so that could be concluded that the use of the battery on the motorcycle becomes more wasteful and the battery life will be shorter.ABSTRAKBahan Bakar Minyak (BBM) menjadi salah satu bahan bakar yang digunakan untuk menggerakkan kendaraan seperti sepeda motor.
