Abstract

The grounding system in the distribution transformer substation is very important for the reliability of the supply of electrical energy and protects humans and equipment from overvoltages or leakage currents, besides that the mainly good neutral grounding system will produce the perfect voltage. To protect humans and distribution substation equipment BA 003 Distribution Transformer 250 KVA from touch voltage, especially in the dry season, sunny weather and peak loads using a 250 KVA Transformer requires parallel grounding Arrester and Grounding Body or Transformer shell. From the measurement results, the peak load occurs at night with the loading reaching 54% of the 250 KVA distribution transformer capacity of 194 KVA. For the measurement of the largest resistance on the grounding of the Transformer Arrester of 8.1 Ω, occurs at 14.00 - 15.00 WIB, the greatest resistance on the grounding of the Transformer Body or Shell of 8.3 Ω occurs at 14.00 - 15.00 WIB. From the parallel measurement of the grounding installation of the Transformer Arrester and the Transformer Body or Shell of 7.7 Ω at 14.00 - 15.00 WIB, with sunny weather conditions during the day.ABSTRAK Sistem Pentanahan  pada gardu transformator distrbusi sangatlah penting untuk kehandalan suplai energi listrik serta melindungi manusia dan peralatan dari tegangan lebih atau arus bocor, selain itu sistem pentanhan terutaman pentanhan netral yang baik akan menghasilkan  tegangan yang sempurna. Untuk melindungi manusia serta perangakat gardu distribusi BA 003 Transformator Distribusi 250 KVA dari tegangan sentuh terutama pada musim kemarau, cuaca cerah dan  beban puncak penggunaan Transformator 250 KVA diperlukan paralel grounding Arrester dan Grounding Bodi atau cangkang Transformator. Dari hasil pengukuran  Beban puncak terjadi pada malam hari dengan pembebanan mencapai 54% dari kapasitas transformator distribusi 250 KVA sebesar 194 KVA.

Abstract

This study aims to anticipate a high value of grounding resistance by utilizing drainage or waste water from household waste as a planting medium to reduce the value of grounding resistance. The research method used is an experimental method of testing and measuring at field locations. In this study, a round rod electrode is coated with copper, namely testing with one electrode rod and two electrode rods that are installed in parallel or better known as the use of a driven rod. The results showed a decrease in the value of the grounding resistance where the average value for 1 grounding rod was 18.32 ohms and 11.82 ohms for the measurement of 2 grounding rods installed in parallel. From the test results, there was a decrease in the resistance value of 59.52% for 1 electrode rod and a 51.75% decrease for 2 electrode rods, where the decrease in the resistance value in the field was caused by factors of water, humidity and used water minerals from household waste. In conclusion, housing with reddish yellow podzolic soil that is clay (high soil resistance) by utilizing water drainage is a solution to reduce grounding resistance.

Abstract

Permasalahan pembumian yang selalu dialami adalah resistivitas tanah atau lahan dimana pada lahan tanah berpasir meliliki resistivitas tanah yang cukup tinggi, bila menggacu pada PUIL 2011 resitivitas tanah pada tanah berpasir  bernilai 200 Ω. Sehingga untuk menurunkan resistivitas pada tanah pasir, maka untuk penanaman elektroda batang diperlukan  resitivitas tanah yang rendah, maka dipilihlah lokasi saluran air bekas pada lahan tanah berpasir yang basah.  Pemilihan lahan tanah berpasir yang basah menunjukan penurunan resistivitas tanah yaitu mencapai 129,27 Ω. Dengan resistivitas tanah yang rendah akan lebih mudah memproteksi manusia dan peralatan-peralatan listrik terhadap sentuhan langsung dari arus bocor atau tegangan induksi sehingga arus bocor tersebut langsung dialirkan kedalam tanah. Dengan turunnya resistivitas lahan tanah berpasir tentunnya terjadi penurunan pada resistansi pentanahan, pada penelitian ini pengujian penanaman grounding rod untuk menentukan nilai resistansi pentanahan dilakukan didaerah desa sukomoro kabupaten banyuasin yang memiliki spesifikasi tanah berpasir. Dengan metode pengukuran 3 titik maka dari hasil pengujian didapat nilai resistansi terbesar dengan menggunakan satu elektroda batang mendapatkan nilai resistansi pentanahan sebesar 67,4 Ω. Nilai resistansi pentanahan terjadi penurunan dengan menambahkan elektroda batang yang dipasang sejajar berjarak 3 meter disetiap penanaman elektroda batang, pada pengukuran menggunakan dua batang elektroda yang dipasang sejajar nilai resistansi yang didapat sebesar 43,6 Ω dan terjadi penurunan Kembali bila dipasang dengan tiga batang elektroda yang dipasang sejajar yaitu 24,4 Ω. Sehingga pemasangan elektroda batang pada lahan berpasir basah yang digenangi air memiliki dampak penurunan resistivitas pentanahan dan penurunan resistansi pentanahan.Kata kunci : Resistivitas tanah, Resistansi pentanahan, Lahan tanah pasir basah.

Abstract

The research was conducted by assuming when the hotel room was fully occupied by guests. This research is to find out in more detail about the use of energy, especially for electrical energy at the Carrissima Hotel Palembang, to find out and implement energy saving opportunities and increase the efficiency of electricity use. The research method used is the literature method, interview method, and observation method. From the calculations carried out, the results obtained for hotel lighting, especially in the hotel lobby, cannot be said to be effective in the use of electrical energy, from the calculations obtained the intensity of lighting is 16.25 Watt/m2, while the maximum limit specified is 20 Watt/m2, while for rooms hotels, the intensity of lighting is 5.16 Watt/m2, while the maximum limit specified is 17 Watt/m2. So the intensity of the Carrissima hotel room does not have an indication of energy wastage, but it is not efficient, lastly for the use of Air Conditioning (AC) at the Carrissima hotel, from the results of these calculations based on the Energy Consumption Index (IKE), where the level of comfort and energy saving in air-conditioned buildings is 23.75 to 37.75 W/m2. The use of air conditioning at the Carrissima hotel is above the convenience of wasting energy. The highest AC power intensity is on the 2nd and 3rd floors, which is 18.33 W/m2, while the lowest intensity is on the 1st floor, which is 1.38 W/m2.
