Abstract

The problem facing by city of Jakarta today is the increasing volume of waste, reaching 7,000 tons per day sent to Bantar Gebang TPST which is currently not handled properly. The purpose of this research was to analyze the application of Landfill and Thermal Waste Power Plant (PLTSa) in Bantar Gebang TPST from the perspective of Energy Security by measuring Energy Supply Security Index (ESSI) using 4 dimensions and 5 approach indicators : Availability (Indicator: Working hour per year), Accessability (Indicator: Access to technology), Affordability (Indicator: Cost of generation per kWh) and Acceptability (Indicator: Avoided CO2 Emission kg per MWh and percentage reduction in waste volume per day). Energy security analysis results are obtained: aspects of availability with working hour indicators per year: PLTSa Landfill = 0.95, PLTSa Thermal = 0.98; aspects of accessibility with ease of technology access indicators: PLTSa Landfill = 0.74, PLTSa Thermal = 0.58; affordability aspects with indicators of the cost of electricity generation: PLTSa Landfill = 0.99, PLTSa Thermal = 0.983; aspects of accessability with two indicators, avoided (CO2) emission: PLTSa Landfill = 1.0, PLTSa Thermal = 0.14, and the percentage of waste reduction: PLTSa Landfill = 0.50, PLTSa Thermal = 0.85.

Abstract

In the current era of technological and information advancements, the growth of industry and business is becoming faster and faster. But this also encourages higher energy use and makes energy use a major contribution to operational costs that must be spent. This study aims to conduct a comparative analysis of Energy Consumption Intensity (IKE) at the Mercure Pontianak Hotel and the Ibis Styles Hotel SoekarnoHatta Airport Jakarta. The method used in this study is the Survey and Literature Study methods. Primary data is obtained from the 2018 Electricity Bill. The data is then used to calculate the Energy Consumption Intensity and then a simulation of energy savings using solar solar with Homer software simulation. The results showed that the IKE in the Mercure Pontianak Hotel building is bigger than the Ibis Styles Hotel SoekarnoHatta Airport which is 323,390 kWh / m2 / year meaning the energy usage in the Mercure Pontianak Hotel building is greater than the Ibis Styles Hotel SoekarnoHatta Airport Jakarta building with a difference of 79,389 kWh / year with a building age difference of +/- 5 years older Mercure Pontianak Hotel while the building area and number of rooms are almost the same. The simulation results of using solar cells obtained energy production of 221,866 kWh per year at a cost of Rp. 972 / kWh, meaning energy savings of 6-8% a year.

Abstract

Industrial and business growth develops rapidly from time to time. This also encourages higher energy use and energy use is a major contributor to operational costs. This study aims to carry out planning and economic studies in the use of PV towards a low-energy building at Hote Inaya Putri Bali. The method used in this research is the survey method and literature study. Primary data is obtained from the 2019 Electricity Bill. The data is then used to calculate the Intensity of Energy Consumption, then taken from energy simulations using solar solar with Homer software simulations. The results showed that the IKE in the Inaya Putri Bali Hotel building was 131.8 kWh / m2 / year, meaning that energy use in the Inaya Putri Bali Hotel building was still efficient. Using the solar cell simulation results, the energy obtained is 443,732 kWh per year at a cost of Rp. 972 / kWh, which means energy savings of Rp. 35,942,292 per month or 14.5% per year.

Abstract

Untuk mengurangi ketergantungan yang sangat besar terhadap energi fosil yang mulai habis, perlu pemanfaatan energi terbarukan yang berasal dari sumber lain yang bukan berasal dari fosil. Salah satu energi bukan fosil yang dapat dimanfaatkan adalah energi angin yang bisa diubah menjadi energi listrik. Dalam tulisan ini energi listrik tersebut digunakan sebagai sumber daya listrik bagi data recovery center (DRC). DRC ini adalah tempat penyimpanan data cadangan dari Data Center, yang merupakan pusat penyimpanan data dengan server yang beroperasi 24 jam sehari, tujuh hari seminggu dan harus berada dalam kondisi lingkungan yang terkendali, hal tersebut menjadikan Data Center dan DRC sebagai salah satu pengguna listrik terbesar di dunia. DRC merupakan tuntutan dari kemajuan teknologi informatika yang menuntut tersedianya penyimpanan data yang besar dan aman, dimana syarat utama DRC adalah letaknya sebaiknya cukup jauh dari ibukota/kota besar sehingga fungsinya sebagai pusat cadangan data terpenuhi sewaktu Data Center terkait mengalami bencana (banjir, gempa bumi, dll) serta diperlukannya tenaga listrik yang stabil untuk menjaga data yang disimpan tetap aman. Dalam tulisan ini akan dibahas potensi energi angin yang bisa diubah menjadi energi listrik dan digunakan sebagai sumber daya listrik Data Recovery Center (DRC) di wilayah Pandeglang, Jawa Barat. Adapun penelitian yang dilakukan adalah melalui studi pustaka, informasi teknis turbin dan informasi teknis mengenai kecepatan angin di Indonesia yang didapat dari jaringan internet.

Abstract

This paper discusess the calculation of solar photovoltaic energy using a probabilistic approach in Nias and Mentawai districts. The application used is the @RISK Risk Analysis Project Model. In this research, the calculated random variable is the average temperature, the length of sunshine per month and solar radiation according to the regional zone. These three variables are fluctuating, so that the approach of each varianble uses a uniform distirbution function. From the three variables, it can be calculated that the energy generated by solar photovoltaic with a capacity of 100 Wp in Nias Regency is 21.062,57 kWh in one year with a probability of 55% and a capacity factor of 24,04%. Meanwhile, in Mentawai District, the same solar photovoltaic capacity of 100 Wp produces 19.249,47 kWh of energy with a probability of 50% and a capacity factor of 21,97%. From the results of this study it can be seen that the average temperature, duration of solar radiation and solar radiation can determine the electrical energy that can be generated by solar radiation can determine the electrical energy that can be generated by solar photovoltaic

Abstract

Coronavirus Disease 2019 (COVID-19) has been declared by WHO as a global pandemic and in Indonesia it is stated as a type of disease that causes public health emergencies and non-natural disasters, so it is necessary to make prevention efforts including prevention and control (Kemenkes RI, 2020) regarding prevention guidelines. and control of coronavirus disease 2019 (COVID-19). One way to prevent the spread of covid-19 is to spray disinfectants on objects suspected of having a virus. Especially for the human body, disinfectant spraying is carried out in a specially designed room or room. These booths are placed in markets, malls, schools, places of worship and so on. This research was conducted from September 2020 to December 2020 at the Faculty of Engineering, Christian University of Indonesia, Jakarta. Based on the test, it was found that the temperature and humidity can be displayed on the LCD and mobile phones via the Blynk application. Temperature regulation is done by activating or deactivating the exhaust fan and fan. At a temperature of> 280C the exhaust fan and fan will be active, then not active if the temperature is ≤280C. This tool has a measurement accuracy level for a temperature of 99.99% and 99.98% humidity with a thermohygrometer as a measurement reference tool.
