Abstract

ABSTRAKDari banyaknya strategi yang diusulkan untuk proses self-assembly pada swarm robotics, hanya beberapa grup riset berkonsentrasi di bidang ini yang mengusulkan proses paralel pada penggabungan antar robot. Tetapi, strategi ini hanya digunakan ketika sebuah robot memerlukan tumpuan dari dua robot atau lebih pada satu waktu. Berdasar pada kebutuhan untuk menyebarkan ratusan hingga ribuan robot pada satu swarm, strategi penggabungan antar robot satu-demi-satu memerlukan waktu yang sangat lama untuk diselesaikan. Di artikel ini, strategi self-assembly antar robot pada suatu swarm secara paralel diusulkan untuk mengurangi waktu proses self-assembly dengan menempatkan sejumlah robot di posisi tertentu. Saat penggabungan, robot-robot ini akan bergerak menempatkan dirinya sesuai dengan posisi akhir yang ditargetkan. Hasil menunjukkan bahwa strategi ini dapat mereduksi waktu proses self-assembly hingga setengah dari waktu yang diperlukan dengan proses penggabungan satu-demi-satu.Kata kunci: swarm robot, self-assembly, proses paralel ABSTRACTDespite the number of strategies proposed for self-assembly process in swarm robotics, only few research groups working in this area have proposed the parallel process of robots assembled each other. However, this strategy only works when a robot needs to be supported by two or more robots in a time. When deploying hundred to thousand robots in a swarm is required, the strategy of robots connecting to the structure of assembled robots in a one-by-one manner requires an extremely long time to accomplish. In this paper, a strategy of parallel selfassembly for robots in a swarm is proposed for reducing the self-assembly process time by placing a number of robots at particular positions. While connecting, they will move to position themselves appropriately to the targeted final structure. Result shows that this strategy can reduce the process of self-assembly time up to half of the time required for one-by-one process.Keywords: swarm robots, self-assembly, parallel process

Abstract

ABSTRAK Langkah utama dan mendasar yang diperlukan untuk navigasi pada robot secara autonomous pada medan yang tak beraturan dan tidak diketahui keadaannya secara dinamis, setidaknya adalah identifikasi koordinat titik jalan (waypoint), tindakan yang harus dilakukan di titik jalan, identifikasi dimensi kerja, dan hambatan yang diketahui. Penelitian ini bertujuan untuk mengimplementasikan titik jalan otomatis (automatic waypoint) pada robot pencari potensi keberadaan korban pasca bencana, dilengkapi dengan kemampuan robot untuk navigasi dari titik awal berjalan mencari potensi keberadaan korban sebagai titik acuan hingga kembali ke titik awal (return trip) secara autonomous. Metode yang digunakan pada perancangan sistem merupakan pengembangan dari metode waypoint menjadi automatic waypoint untuk navigasi secara autonomous. Hasil yang didapat, robot mampu mendeteksi keberadaan korban maksimal dalam radius 3 meter di dalam simulasi reruntuhan. Ketercapaian rata-rata akurasi pembacaan posisi robot terhadap korban dan titik awal sebesar 6,76 meter. Kata kunci: robot, autonomous, automatic waypoint, korban, return trip. ABSTRACT There are necessary steps required for a robot to navigate autonomously on an unknown and uncertain environment. Those steps consist of the identification of the waypoint coordinates, the actions to be conducted, the identification of the environment?s dimension, and the known obstacles. This study aims to implement an automatic waypoint on a robot for searching the potential existence of post-disaster victims. The robot is equipped with the ability to navigate from the starting point to search for potential victims and then return to the starting point autonomously. We modified the existing waypoint method into an automatic waypoint for autonomous navigation. Results show that the robot is able to detect the presence of the victim within the maximum radius of 3 meters in the simulation of rubble (tables, chairs, wood and iron poles). The accuracy of robot in reading the position of the victim and the starting point is 6,76 meters. Keywords: robot, autonomous, automatical waypoint, victims, return trip.

Abstract

ABSTRAKPada penelitian ini dikembangkan sistem remote control yang digunakan untuk melakukan setting (pengesetan) waktu pada sistem Automatic Time Switch (ATS) secara ‘jarak jauh’, sehingga lebih mempermudah setting waktu sistem ATS yang digunakan sebagai saklar otomatis berbasis waktu untuk pengontrolan lampu halaman. Pengembangan ini merupakan langkah untuk menyempurnakan sistem ATS-C2I versi 1 yang hanya memiliki beberapa setting waktu default. Referensi waktu yang dipergunakan pada sistem ini menggunakan komponen Real Time Clock (RTC)-DS1307 yang memiliki pengaturan setting waktu dalam satuan detik, menit, jam, hari, bulan dan tahun. Setting waktu ini ditransmisikan dari sistem remote control menuju sistem ATS melalui sistem komunikasi frekuensi radio 315 MHz. Dari hasil pengujian diperoleh bahwa sistem ATS telah dapat menerima setting waktu dari sistem remote control dengan utuh dalam jangkauan jarak maksimum 22 meter. Selain itu, sistem ATS pun telah berfungsi untuk mengatur aktifasi saklar lampu sesuai dengan setting waktu yang diberikan. Keberadaan sistem ATS-C2I versi 2 ini dapat menghemat pemakaian aliran listrik serta dapat membantu meningkatkan keamanan rumah pada saat ditinggalkan pemiliknya.Kata kunci: Automatic Time Switch (ATS), Real Time Clock (RTC), remote control, frekuensi radio, saklar lampu.ABSTRACTA remote control system applied for remote time setting of the Automatic Time Switch (ATS) system was developed in this current research to make easier on the performing of time setting for ATS system that implemented to control a switch of front yard lamp automatically based on time setup. This development was also a further step to improve the first version of ATS-C2I system that just has some in system default time setup options. Time reference for this system utilized a Real Time Clock (RTC)-DS 1307 that has time setting duration from second, minute hour, day, month and year. This time setting was transmitted from remote system to ATS system through 315 MHz radio frequency communication system. From the experiment results, the ATS system has been able to receive time setting from remote control system completely on maximum distance range 22 meters. Beside of that, the ATS system has been able to control a lamp switch activation based on user time setting setup. The availability of the second version of ATS-C2I system can increase saving energy as well as can help to improve a home security system.Keywords: Automatic Time Switch (ATS), lamp switch, radio frequency, Real Time Clock (RTC), remote control.

Abstract

In Indonesia, many farmers use pesticides, especially in East Kalimantan, specifically in Loa Janan Ulu Village. Farmers use pesticides as an effort to reduce pest or insect attacks. The use of pesticides poses a risk to humans in the form of acute chronic poisoning and even death. Cholinesterase is an enzyme found in cell fluids whose job is to stop the action of acetylcholine by hydrolyzing it into choline and acetic acid. The aim of this research was to determine the levels of the cholinesterase enzyme in farmers who use pesticides in Loa Janan Ulu village. The type of research used was descriptive with a sample of 80 farmers in Loa Janan Ulu village who met the inclusion and exclusion criteria. The sampling technique was carried out using purposive sampling, with univariate analysis. The research results are based on the characteristics of respondents in the largest age group, namely 51-60 years (15 respondents), working period 21-30 years (14 respondents). The frequency of spraying was once a week (25 respondents). It can be concluded that in 33 samples the cholinesterase enzyme levels of 95% of farmers met normal standards and 5% did not meet normal standards.
