This research was conducted to determine the electrical energy demand of PT. PLN (Persero) UP3 Sukabumi using analytical methods, econometrics and trends in 2019-2029. This research used a combined method which was a method compiled by combining several the models such as econometrics, analysis, and trends with a sectoral approach which was an approach by grouping electricity consumers into four sectors, namely the household, commercial, public, and industrial sectors. The results showed that the population rate rose 0.36% per year, the growth GRDP rate rose 6.26%; the number of electricity customers in the household sector rose 5.26% per year, the number of commercial electricity customers rose by 13.96% per year, the number of public sector electricity customers rose 7.58% per year, and the number of industrial sector electricity customers rose 3.53 % per year. it can be concluded that over the next 10 years the electricity demand will increase by 3,080.83 Gwh with an average growth of 10.69% per year.
The purpose of this study is to find out how much electric load to Sukabumi from 2019 until 2029 at PT. PLN (Persero) UP3 Sukabumi. Forecasting of electrical load using historical data. This research uses a combined method, which is a method compiled by combining several models such as econometrics, analysis, and trends with a sectoral approach, which is an approach by grouping electricity consumers into four sectors, namely the resident, commercial, public, and industrial sectors. The population forecast of Sukabumi in 2019-2029 shows an average growth of 0.36% per year. Gross Regional Domestic Product (GRDP) for resident sector growth of 6.26% per year, commercial sector growth of 6.26% per year, public sector growth of 6.26% per year, and the industrial sector growth of 10.07% per year. The electric customers for the resident sector growth of 5.26%, commercial sector growth of 13.96% per year, public sector growth of 7.58% per year, and industrial sector growth of 3.53% per year. The electric contracted power for the resident sector growth of 5.19% per year, commercial sector growth of 14.96% per year, public sector growth of 7.28% per year, and industrial sector growth of 3.36% per year. Growth of population, GRDP, number of electric customers, and power contracted, as shown in forecasting 2019-2029, will affect to increasing electrical load. The total electrical load will be 1,054.22 MVA in 2019 and 2,043.80 MVA in 2029 or growth of 6.74% per year.
E-learning is very supporting the implementation of learning, because it uses teaching materials that are independent, so it can be accessed at any time. E-learning can improve students’ absorption of subject matter, active student participation, and the ability and quality of information that when using ordinary devices will be difficult. If carefully designed, e-learning can increase levels of learning interactions. Unlike the case with conventional learning, not all students can ask questions or express their opinions in the discussion, because the opportunities are very limited. Based on these assumptions, it is necessary to conduct a study of the e-learning prototype development strategy. Specifically, the purpose of this study was to develop a prototype of an electronic learning device using Moodle. This research is Research and Development with the Four-D development model. The results of the study were in the form of a prototype e-learning CASE-based Mathematics learning device. In conclusion, the prototype can be developed into a complete mathematics learning media.
This article aimed to analyze the energy consumption and energy efficiency in government office buildings of Bengkulu, Indonesia. This research was conducted using a quantitative descriptive method. The research step begins by observing the initial conditions of Energy Consumption Intensity (ECI) to determine the category of buildings that are efficient or not in terms of energy use, then collecting data on the profile of the use of the building and its rooms, recapitulation of the use of energy sources (both electrical energy and other chemical energy), a list of equipment that consumes electrical energy (lighting, air conditioning, and others). Furthermore, measuring the performance of systems and equipment that consumes energy and conducting efficiency analysis to then make recommendations with operating settings, to replace inefficient equipment with more efficient equipment. The final step is to draw conclusions about the final Energy Consumption Intensity (ECI) obtained based on the results of the analysis and recommendations obtained on the previous Energy Consumption Intensity (ECI) value. It can be concluded that the final Energy Consumption Intensity (ECI) of government office buildings of Bengkulu based on the results of the analysis and recommendations such as performing preventive maintenance on air conditioners, the temperature of the air conditioner is set to always be at 24°C, replacing the type of lamp in the artificial lighting system that still uses TLD lamps with LED lamps, and efforts in organizing energy management systems will decrease around 13 percent from the previous Energy Consumption Intensity (ECI) or down from 40.9 kWh/m2/year to be 35.6 kWh/m2/year.
Pelatihan Perbaikan Dan Perawatan Air Conditioner (AC). Pelatihan ini bertujuan untuk memberikan pengetahuan dan ketrampilan perbaikan dan perawatan Air Conditoner kepada TKI yang sudah kembali ke Indonesia sehingga mendapatkan bekal yang positif. Pelaksanaan pelatihan perbaikan dan perawatan Air Conditioner dilaksanakan di TUK SMKN 26 Jakarta. Pelatihan dibagi dalam 2 (dua) sesi, yaitu sesi teori, dan sesi praktik. Pada sesi pertama peserta diberikan pengetahuan terkait dengan teori berupa materi - materi penunjang praktik. Materi disampaikan dengan metode ceramah, dan diskusi/tanya jawab. Dan pada sesi kedua peserta diberikan ketrampilan praktik terkait pencucian unit AC (pembersihan indoor dan outdoor) dan pengecekan performa AC. Materi disampaikan dengan metode demontrasi/ peragaan dan praktik yang diikuti oleh peserta. Kesimpulan dari pelatihan ini adalah peserta pelatihan peduli dan antusias terhadap materi pelatihan pelatihan perbaikan dan perawatan Air Conditioner, peserta pelatihan sangat berperan aktif dalam kegiatan pelatihan perbaikan dan perawatan Air Conditioner, peserta pelatihan sebagian besar dapat memahami materi yang diajarkan meskipun materi yang diajarkan merupakan hal yang baru, peserta pelatihan memiliki pengetahuan terkait perbaikan dan perawatan Air Conditioner, peserta pelatihan memiliki ketrampilan berkaitan perbaikan dan perawatan Air Conditioner.
