Abstract

Bale Gong is a very important building in the temple. This is because every ceremony at the temple is accompanied by a gamelan gong. In every piodalan ceremony at Sindetan Temple always make a tent for the Bale Gong. Tents that are installed are usually made of materials that are easily damaged, namely bamboo, coconut leaves, and tie rope. In making these tents, it takes a lot of people who have expertise and cost of making the tent is quite expensive. After completing the ceremony, the tent is dismantled where the materials cannot be reused at the next piodalan ceremony. This is because these materials will break down quickly. The solution to this problem and at the same time is the goal of this service is in the form of innovation in making tents from strong and durable materials. The materials that will be used are iron and cloth. This iron is used instead of bamboo and cloth is used instead of slepan and tie rope. The final result of this service is has designed and made tent that are strong, aesthetic, comfortable, and easy to assemble and disassemble. The tents that have been made are installed in Bale Gong and then handed over to the residents of Sindetan Temple. Keywords: Bale Gong, Sindetan Temple, tent, design, strong, aesthetic.

Abstract

Liquid waste cannot be disposed of directly, so it must be processed so as not to cause pollution to the surrounding environment. Both BOD (Biological Oxygen Demand) and COD (Chemical Oxygen Demand) treatment, oxygen is also required so that the quality of the liquid waste is safe for the environment. Liquid waste treatment mostly utilizes aerators to produce high pressure air in liquid waste containing oxygen (O2). The problem that occurs in most wastewater treatment is the determination of the working time of the aerator, resulting in excessive use of electrical energy, but the results of the waste are still within unsafe limits. In general, the operating time of the aerator is manually, this causes the use of electrical energy to be wasteful. This research was conducted, how to develop a control system design for aerator operating time on the quality of liquid waste. The development of the control system used is Sugeno interval fuzzy logic type-2 with 2 (two) input types of Gauss membership function. The advantage of interval fuzzy logic type-2 over type-1 fuzzy logic is the ability to provide more accurate output for higher input uncertainty. The input variables used are waste volume and COD reduction, while the output is the aerator's operating time. The results obtained in the system design can be applied properly and in accordance with the setting point with an average aerator operating time of 6.8 hours and can reduce the use of electrical energy by 38.2%.

Abstract

This study aims to analyze and compare the performance of three frequency load controller methods in a hybrid generator consisting of three types of energy generation, namely microhydro, diesel and wind. The controller methods being compared are the PID (Proportional Integral Derivative) method, ANFIS (Adaptive Neuro-Fuzzy Inference System), and Fuzzy. This analysis was carried out to improve the efficiency and stability of the hybrid generating system by optimizing the frequency load controller. Frequency instability can occur due to load fluctuations, changes in environmental conditions, or system disturbances. Therefore, the use of an effective and adaptive controller method is very important in maintaining the stability and reliability of the hybrid generator system. The analytical method used in this study involved data collection and computer modeling. The required data includes information on load variations, energy production, and environmental conditions. Furthermore, the PID, ANFIS, and Fuzzy methods are applied to the data to build a frequency load controller model. The results of the analysis show that the three controller methods have different performance in maintaining frequency stability in the hybrid generator system. The PID method provides a fast and accurate response to load fluctuations, but is less adaptive to environmental changes. While the ANFIS method is able to adapt well to changes in system conditions, it requires time for model training. Fuzzy methods can provide control that is more adaptive and tolerant to disturbances, but may require more complex tuning. However, in general, the use of intelligent controller methods such as ANFIS and Fuzzy can improve the performance of hybrid generators by producing more adaptive and stable controls. This research has important implications for the development of more efficient and reliable hybrid power systems. By choosing the right controller method, hybrid power plants can provide energy in a more stable and environmentally friendly manner, and reduce dependence on limited fossil resources. Therefore, this research can make a significant contribution to the development of renewable energy and sustainable development in the future.

Abstract

Sistem tenaga listrik yang baik merupakan suatu sistem yang dapat melayani beban secara berkelanjutan serta tegangan dan frekuensinya stabil. Perubahan frekuensi terjadi disebabkan oleh permintaan beban yang berubah-ubah dari waktu ke waktu. Pengaturan frekuensi pada sistem pambangkit PLTG tergantung pada pengisisan daya aktif dalam sistem. Pengaturan daya aktif ini dilakukan dengan mengatur besarnya kopel penggerak generator. Pengaturan frekuensi dilakukan dengan menambah dan mengurangi jumlah energi primer (bahan bakar) dan dilakukan pada governor. Simulasi dalam studi analisis governor sebagai load frequency control pada PLTG menggunakan fuzzy logic controller dilakukan dengan memberikan empat jenis pembebaban yaitu sebesar 0,1 pu, 0,2pu, 0,3 pu dan 0,4 pu. Simulasi dilakukan untuk membandingkan output respon frekuensi dinamik dan waktu kestabilan yang dihasilkan menggunakan fuzzy logic controller dengan PI controller. Berdasarkan hasil analisis perbandingan yang dilakukan membuktikan bahwa governor sebagai load frequency control menggunakan fuzzy logic control lebih baik dibandingkan dengan menggunakan PI kontroller. Hal ini dapat dilihat dari output respon frekuensi dan waktu kestabilannya.

Abstract

Pada jaringan transmisi sering terjadi berbagai macam jenis gangguan, antara lain gangguan hubung singkat satu phasa ke tanah, gangguan hubung singkat phasa ke phasa, gangguan antar phasa ke tanah dan gangguan simetris. Pendeteksian terhadap gangguan tersebut dapat dilakukan dengan metode jaring syaraf tiruan. Jaring syaraf tiruan terdiri dari sejumlah elemen penghitung tak linier yang masing-masing dihubungkan secara paralel melalui suatu pembobot. Proses training pada jaring syaraf tiruan ini terdiri dari proses pelatihan terhadap gangguan hubung singkat satu phasa ke tanah, gangguan hubung singkat phasa dengan phasa, gangguan hubung singkat antar phasa dengan tanah, dan gangguan simetris. Proses pelatihan pada jaringan transmisi ini menggunakan konfigurasi 6 data intput, 10 hidden layer, 6 data target, dan 6 output (6-10-6-6). Hasil pelatihan menunjukkan bahwa nilai arus dan tegangan gangguan untuk semua jenis gangguan pada jaringan transmisi berhasil di bangkitkan, dimana output berupa nilai tegangan dan arus dari proses pelatihan akan disimpan dan dijadikan sebagai refrensi untuk menentukan jenis gangguan hubung singkat yang terjadi pada jaringan transmisi. Data hasil simulasi jaringan transmisi dapat dikatakan normal saat mendekati nilai output atau sebaliknya ketika jaringan transmisi mengalami gangguan hubung singkat. [TURNITIN CHECK 75 19042017]

Abstract

The power system must be able to server the load in a sustainable manner with good service quality, such as constant voltage and frequency, quickly stabilized when load changes occur. The control generator automatically changes the frequency to the highest value when the system changes every time. This is called AGC. To keep the frequency in a stable state required frequency control system. Currently developing a lot of control system with fuzzy logic method. The simulation is performed using 5 membership functions and gives a loading of 0.1 pu, using MATLAB-Simulink software. From the analysis result, the comparison of output of frequency response in overshoot condition with conventional method yielded , settling time of 20.5 second. While the fuzzy logic controller method produces frequency response output in the overshoot state that is , settling time is 12 seconds. Whit the fuzzy logic controller method produces better performance and faster than conventional methods.
