The use of electrical energy increases globally every year. The laboratory prediction energy control system (LPECS) predicted energy demand. This research was conducted in the Electrical Engineering Vocational Education laboratory by comparing the artificial neural fuzzy system (ANFIS) with the fuzzy logic. The comparison of methods aimed to determine their reliability in the energy demand prediction systems. The results showed that the minimum value of the target data using the conventional method (actual data) was 44.42%. Meanwhile, the prediction data using the ANFIS method was 44.33%, and the prediction data using the fuzzy method was 59.31%. The maximum value of the conventional ways (actual data) of ANFIS and fuzzy was similar by 77.59%. The RMSE ANFIS value was 0.1355%, the mean absolute percentage error (MAPE) was 0.2791%, and the fuzzy logic was 0.1986%. Thus, the ANFIS is applicable to determine the minimum and maximum values. Meanwhile, fuzzy can only show the maximum value but cannot reach the minimum value properly.

This research aimed to explore the results of the evaluation of Electrical Installation Training of the Technical Support Unit of Employment Training Center of Pandeglang Regency based on aspects including context, input, process, product, and outcome, so that recommendation can be obtained for the next training. This study employed a qualitative descriptive method. The CIPPO evaluation model was used in this study. The results indicated that while the setting, process, and product elements could be classified as satisfactory, the input and outcome aspects remained in the poor category. Nonetheless, even with remaining limitations in terms of input and implementation outcomes, the training program can run well. This electrical installation training can be extended by strengthening program components on the input side, particularly facilities and infrastructure, as well as on the output side, in order to maximize labor absorption and reduce unemployment.

Tingginya aktivitas manusia dalam memenuhi kebutuhan ekonomi semakin mengurangi waktu bagi manusia untuk berada di sekitar rumah, baik untuk berkumpul bersama keluarga maupun untuk menjaga keamanan tempat tinggal tersebut, sehingga banyak terjadi hal-hal yang tidak diinginkan seperti kebakaran rumah dan pencurian. Penelitian ini bertujuan untuk merancang peralatan sistem pemantau jarak jauh menggunakan multisensor yaitu sensor api, sensor asap dan motion sensor yang dapat memantau kondisi rumah dari bahaya kebakaran dan pencurian. Sistem ini mampu memberikan informasi dari kondisi rumah secara jarak jauh dengan menggunakan layanan SMS (Short Message Service). Perancangan alat ini menggunakan mikrokontroller ATMega16 yang berfungsi sebagai sarana pengolahan data berupa Protocol Data Unit (PDU) untuk pengiriman/penerimaan SMS (SMSGateway).Hasil pengujian menunjukkan bahwa respon waktu SMS yang dikirim dari sistem tidak lama, sehingga informasi dapat terkirim dengan cepat kepada handphone user untuk mengetahui keadaan rumah dari bahaya kebakaran dan pencurian. Sistem dapat memberikan informasi SMS kepada 3 nomor handphone secara jarak jauh. Sistem ini juga didukung oleh back-up power supply yang berfungsi sebagai suplai tegangan cadangan untuk menedukung kinerja sistem pada saat listrik utama yang berasal dari PLN terputus.

The energy use that is in excess of practicum students’ needs and the disturbed comfort that the practicum students experience when conducting practicums in the Electrical eengineering vocational education (EEVE) laboratory. The main objective in this study was to figure out how to predict and streamline the use of electrical energy in the EEVE laboratory. The model used to achieve this research’s goal was called the adaptive neuro-fuzzy inference system (ANFIS) model, which was coupled with principal component analysis (PCA) feature selection. The use of PCA in data grouping performance aims to improve the performance of the ANFIS model when predicting energy needs in accordance with the standards set by the campus while still taking students’ confidence in conducting practicum activities during campus operating hours into consideration. After some experiments and tests, very good results were obtained in the training: R=1 in training; minimum RMSE=0.011900; epoch of 100 per iteration; and R=0.37522. In conclusion, the ANFIS model coupled with PCA feature selection was excellent at predicting energy needs in the laboratory while the comfort of the students during practicums in the room remained within consideration.

A simulation is needed to observe and indicate how much preventive measures influence the pandemic flow, controlling and stopping it. This study succeeded in making a stochastic susceptible infected recovered deceased (SIRD) simulation using Python programming language to determine the effectiveness of prevention methods such as masks policy, social distancing, vaccination, quarantine, and lockdown. Every preventive measure is modeled based on an equivalent actual event and every essential aspect that affects the course of the pandemic. A person is represented as a circle moving freely in two-dimensional space, and disease spreads through person-to-person contact. This simulator then tested using parameters to simulate COVID-19 and found significant results between communities that implement preventive measures and those that do not. We found that within 106 days, 284 people were infected, but when five preventive methods are applied for a total of 33 days, only 31 people were infected. Adequate to simulate epidemic events and their prevention measures, this simulator can also be used as a learning tool with factors in epidemic events such as population density, mobility, infection rate, disease mortality, and every effect of each preventive measure. Users can change and influence the simulation course using interactive and straightforward software tools.
