Abstract

The needs of Tilapia is quite high and  popular for that the needs of this fish increasingly every year. The needs of tilapia should be support also by the availability of its seeds which determan by the ponds water conditions such as temperature, water clarity and its height.  This research designs a  prototype of a system to maintain the optimum temperature condition  in the range of 25°-30° celcius for tilapia seeds pond. When the system  indicate that the water temperature hits 25oC or below, it activate the heater to heat the water pond until it reach the temperature of 28oC. The fish seeds develop well for the water height between 40-60 cm. When the water is too high so the system will activate the pump to drain the pond to the normal level, otherwise the pump will fill the pond whenever the system indicate the water level in the pond is low. The best water for tilapia seeds is a pond with clear and clean water. The the water pond indicate to be muddy it also activate the pump to drain water to the low level and fill it again to the normal level.  This simulation results show that the prototype of automation of water conditioning controller has work properly to  drain, to fill, to clarify, to warm the water pond automatically and able to send messages to the user about those condition.  AbstrakIkan nila adalah salah satu jenis ikan yang bernilai ekonomis tinggi sehingga kebutuhan benih maupun ikan yang layak cenderung  meningkat setiap tahunnya. Seiring meningkatnya permintaan ikan maka harus diiringi dengan penyedian benih ikan yang berkualitas, di mana hal ini sangat ditentukan oleh kondisi air kolam seperti suhu, kejernihan dan ketinggian air. Penelitian ini membuat rancang bangun suatu sistem yang mengatur kondisi suhu optimal untuk kolam pembibitan ikan yaitu 25°-30° celcius. Apabila suhu air kolam dibawah 25° celcius maka sistem mengaktifkan heater sampai pada suhu 28° celcius. Untuk ketinggian air yang baik untuk kolam pembibitan adalah berkisar antara 40-60 centimeter. Penelitian ini mensimulasikan tiga level ketinggian yaitu rendah, normal, dan tinggi. Pada saat air berada pada kondisi level air tinggi maka pompa pengurasan aktif hingga ketinggian air sampai pada level normal yang akan menghentikan pompa. Selanjutnya pada saat level air rendah, maka pompa akan mengisi kolam hingga pada level normal yang akan menghentikan kerja pompa. Untuk kejernihan air, kondisi yang diharapkan adalah air yang jernih dan bersih. Pada saat air keruh maka pompa pengurasan akan aktif sampai batas level rendah kemudian melakukan pengisian kembali sampai batas normal. Hasil simulasi penelitian ini memperlihatkan bahwa rancang bangun prototipe otomatisasi kontrol pengkondisian air, sudah dapat melakukan pengurasan, pengisian, penjernihan dan penghangatan otomatis serta mampu mengirim pesan pada pengguna.

Abstract

This research design a sistem to provide room security based on micro-controller. This research designs a system to secure a specific room using a specific code number for that only specific persons have the access to the secured room otherwise the alarm will on as a notification that inappropriate person try to enter the secured room. To enhance the security of the specific room, this research also added two others sensors; PIR sensor and fire sensor. The security system able to activates three conditions simultaneously.When the micro-controller find that one or more conditions meet the requirements, it will activate the alarm. The simulation results show that the alarm activate if somebody enter the room without deactivated the system or the system detects fire spot in the room. ABSTRAKPenelitian ini menyediakan sistem pengaman ruangan yang berbasis mikrokontroler. Mikrokontroller ini dipakai untuk mengontrol pengamanan ruangan yang menggunakan akses kode pin sehingga hanya orang tertentu yang mengetahui kode PIN tertentu dapat masuk dalam ruangan tersebut tanpa alarm berbunyi. Dengan mikrokontroller yang sama, sistem keamanan ruangan dapat ditingkatkan dengan menambah dua jenis sensor yaitu sensor yang peka terhadap tubuh manusia (PIR) dan sensor yang dapat mendeteksi Api.  Sistem pengaman ruangan ini dirancang dengan tiga kondisi yang akan aktif secara pararel. Jika satu atau lebih kondisi terpenuhi maka alarm berbunyi sebagai tanda bahwa ruangan dalam keadaan tidak aman. Hasil simulasi sesuai rancangan bahwa alarm berbunyi jika sesorang berada dalam ruangan tanpa menonaktifkan sistem atau ada nyala api dalam ruangan tersebut. Rancang Bangun Prototipe Pengaman Ruangan Dengan Kode PIN dan Multi Sensor Berbasis Mikrokontroller dapat menjadi model sistem pengaman ruangan yang mempunyai tingkat keamaman yang lebih baik.

Abstract

Currently, people at Lekke Village use electricity supplied by Micro hydro Power Plant. The plant of this turbine is located at about 5-6 km from the village and operates only about 10-12 hours per day, from 06.00 PM in evening to 06.00 AM in the morning. The remote location of the micro hydro plant decreases the received voltage at the community. Besides, the unstable condition of turbine installed at Lekke Village resulted in the fluctuation of the output frequency and voltage.  At dry season, the decrement of water flow makes the decrement of the supplied power from the micro hydro plant. While in rainy season, the turbine sometimes fail to operate properly because of garbage, dry leaves, etc. which fall into the river and blocked its flow. Due to this condition, the needs of electricity at Lekke Village are crucial and needs the installation of solar power to meet the community needs. This activity trains local people to have a basic ability on how to build hybrid power installation of turbine and solar power. For this purpose Pengabdian Kepada Masyarakat (PKM) Team from Enginering Faculty of Atmajaya Makassar University is funded by Dirjen Pendidikan Tinggi, Riset dan Teknologi Kementerian Pendidikan dan Kebudayaan through Kegiatan Bantuan Pendanaan Program Penelitian Kebijakan Merdeka Belajar Kampus Merdeka dan Pengabdian Masyarakat Berbasis Hasil Penelitian dan Purwarupa PTS Ditjen Diktiristek.  This training provides 2 basic skills to local people: 1). How to install Solar Power to be used at Sound System and lighting in the St.Anna church; 2) How to build the control system for the hybridization of micro hydro power-solar power.  This training conducts in 2 consecutive session which is training session and installation session. Training session provide basic knowledge of micro hydro power-solar power to the local people and at the installation session the local people together with the trainer work together to install the solar power at St. Anna Church. This activity installs 2X140 WP solar panel with capacity equal to 140 Watt. The solar panel supported by 2x60 Watt batteries. After the installation, the installed system at St.Anna Church able to work 24 hours, supply 70 Watt Sound System and activate 10 lighting points where each point needs 7 Watt. The hybrid installation equipped with a controller that gives ability to select the input power from micro hydro power or from solar power
