Kinerja sebuah generator sinkron dapat diukur dengan perhitungan efisiensi perbandingan antara daya input pada generator dan daya output generator. PT. Pembangkit Listrik Palembang Jaya memiliki generator sinkron yang tersambung secara sinkronisasi pararel yang dihidupkan secara nonstop atau terus menerus. Suatu efisiensi generator sinkron dapat dipengaruhi oleh jumlah pembebanan dan faktor daya berupa naik turunnya nilai cos phi pembebanan. Menurunnya faktor daya (Cos phi) akan mengakibatkan turunnya sebuah efisiensi. PT. PLPJ menggunakan nilai Cos phi 0.85 dan untuk nilai cos phi optimal pada generator PT. PLPJ sebesar 0.90. Semakin besarnya pembebanan maka akan semakin turunnya sebuah efisiensi. begitu pula sebaliknya, semakin kecilnya pembebanan maka akan naiknya efisiensi.","PeriodicalId":404492,"journal":{"name":"Jurnal Ampere","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115643842","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.   Abstrak Ikan 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.

But in use, the motor quickly decreases its speed and the sound gets louder. This is due to the high value of the losses on the motor, which results in a low value of efficiency, 59.1%. High losses cause the motor to heat up, so that the speed decreases and the sound becomes even more noisy. In the shaded pole induction motor, the iron core is very dominant, it can reach 60% of the total motor material. This will make the magnetic field path long, which can result in lower motor efficiency.
