Authors: Murtono Ari , Budi Edi Sulistio , Hariyadi Herman 
Published: April 2021

Ripel pada tegangan dan arus DC dihindari pada kebanyakan beban-beban DC, karena dapat menambah energi yang tidak perlu. Baterai adalah beban DC, saat aki dalam kondisi diisi oleh charger. Pengisian muatan listrik pada aki memerlukan waktu sampai penuh. kami me-neliti sejauh mana pengaruh amplitudu ripel terhadap kecepatan pe-ngisian penuh pada aki pada frekwensi ripel 100 Hz. Tanda bahwa aki sudah bermuatan penuh, ketika arus beban (I2) sangat kecil atau bahkan mendekati nol. Pada ripel rendah, memerlukan waktu yang lebih panjang, menurut yang ada di penelitian ini pada detik ke 3000, arus I2 masih belum mencapai angka nol. Pada ripel sangat tinggi tinggi, pada detik ke ke 160 arus I2 sdh mencapai mencapai Nol de-ngan lembah negatip. Dapat disimpulkan bahwa riak sangat berpe-ngaruh untuk mengurangi waktu pengisian. Metode penelitian ini, mendesain: rangkaian konverter dc-dc, amplitudu ripple, rangkaian ekivalen baterai, mensimulasi dengan software PSIM, analisis, dan simpulan.

Ripple on DC voltage and current is avoided at most DC loads, because it can add unnecessary energy. The battery is a DC load, when the battery is charged by the charger. Charging an electric charge on the battery takes time to full. we investigated the effect of ripel amplitude on the speed of full charge on the battery at 100 Hz ripple frequency. Sign that the battery is fully charged, when the load current (I2) is very small or even close to zero. At low ripel, requires a longer time, according to what is in this study at 3000 seconds, the current I2 still has not reached zero. At a very high ripel, at 160 seconds the current I2 reaches zero with the negative valley. It can be concluded that the ripple is very influential to reduce the charging time. This research method, design: dc-dc converter circuit, ripple amplitude, battery equivalent circuit, simulates with PSIM software, analysis, and conclusions.

Authors: Sutjipto Rachmat 
Published: April 2021

Obyek dari penelitian ini adalah transformator no 6 di Gardu Induk Kebonagung (150 kV / 20 kV, 60 MVA) di mana pada saat beroperasi akan mengalami fluktuasi pembebanan yang bervariasi. Untuk mendukung proses analisis maka pengambilan data (name plate, data harian trafo, suhu dll) dalam penelitian ini dilaksanakan secara langsung dalam periode tertentu pada transformator no 6 di GI Kebonagung. Setelah dilaksanakan analisa secara perhitungan & grafis maka diketahui bahwa fluktuasi pembebanan dari transformator dan perubahan suhu lingkungan menyebabkan perubahan temperature hotspot dari kumparan. Semakin besar temperatur hotspot dan suhu lingkungan, maka akan berimbas dengan naiknya nilai tahanan transformator. Jika tahanan semakin besar maka menyebabkan nilai rugi tembaga transformator juga akan semakin besar.. Meskipun demikian, besarnya temperature hotspot (52,5oC) masih di bawah standar IEC 60076-7 (120oC) dan besarnya rugi inti (26,47 kW (0,0367 %)) dan rugi total (1.721,99 kW (2,87 %)) juga masih di bawah standar yang ditentukan pada SPLN D3.002-1:2007 yaitu 10% untuk rugi inti dan 5% untuk rugi total transformator.

The object of this research is transformer no. 6 at the Kebonagung Substation (150 kV / 20 kV, 60 MVA) where during operation it will experience variable loading fluctuations. To support the analysis process, the data collection (name plate, daily transformer data, temperatures, etc.) in this study was carried out directly in a certain period in transformer no 6 in Kebonagung GI. After calculating & graphical analysis, it is known that the fluctuation in loading of the transformer and changes in ambient temperature cause changes in the hotspot temperature of the coil. The greater the hotspot temperature and ambient temperature, the higher the impact value of the transformer. If the resistance increases, the copper loss value of the transformer will also increase. However, the magnitude of the hotspot temperature (52.5oC) is still below the IEC 60076-7 (120oC) standard and the amount of core loss (26.47 kW (0, 0367%)) and total loss (1,721.99 kW (2.87%)) are also still below the standard specified in SPLN D3.002-1: 2007 which is 10% for core loss and 5% for total transformer loss.

Autonomatic guided vehicle (AGV) merupakan salah satu jenis robot pengangkut barang yang memiliki roda dan dapat berpindah tempat dengan panduan sensor. Pada saat robot berpindah dibutuhkan kecepatan yang cepat dan akurat, untuk mencapai kecepatan yang konstan. Kecepatan robot akan selalu berubah sesuai dengan lintasan yang dilaluinya. Pengaturan kecepatan agar robot dapat berpindah sesuai dengan kecepatan yang diinginkan atau sesuai dengan set point. Kecepatan berubah – ubah sesuai kondisi seperti pada saat akselerasi lintasan lurus, lintasan berbelok dan pada saat robot akan berhenti. Untuk mencapai target kecepatan yang sesuai maka menggunakan metode fuzzy logic. Metode fuzzy logic adalah metode yang tepat untuk mengontrol kecepatan robot Automatic guided vehicle. Fuzzy logic menggunakan input berupa error dan delta error. Dengan metode fuzzy logic membuktikan bahwa hasil yang didapat dengan set point 30 cm/s dan 40 cm/s robot AGV dapat berjalan secara dengan respon yang cepat dan menghasilkan tingkat osilasi yang rendah.
Automatic guided vehicle is one type of goods transport robot that has wheels and can move places with sensor guidance. When the robot moves, it needs a fast and accurate speed to achieve a constant speed. The speed of the robot will always change according to the path it passes. Speed regulation so that the robot can move according to the desired speed or according to the set point. Speed changes according to conditions such as when the track acceleration is straight, the track turns and when the robot stops. To achieve the appropriate speed target then use the fuzzy logic method. To achieve the appropriate speed target then use the fuzzy logic method. Fuzzy logic method is the right method to control the speed of robots Automatic guided vehicle. This method does not need to always adjust the gain when the load changes or when a set point changes. With this method the results can be analyzed that the fuzzy logic method can stabilize the AGV robot speed to the maximum with a range of 30 to 40 rpm.
