Pertumbuhan pendapatan perkapita rata-rata di Kabupaten Tapak Tuan sampai tahun 2019 diperkirakan sebesar 6%, maka PLN Ranting Tapak Tuan dan Blang Pidie akan mengalami pertumbuhan penjualan lisrik rata-rata sebesar 6,5% dengan pertumbuhan beban sekitar 6,4% per tahun. Beban puncak pada tahun 2019 diperkirakan menjadi 17,7 MW. Dengan asumsi cadangan N-1 (masing-masing PLTD unit terbesar) maka daya mampu Pembangkit yang ada di subsistem Tapak Tuan sebesar 13,3 MW maka pada tahun 2013 akan mengalami deficit sebesar 0,35 MW dan akan terus meningkat bila tidak ada penambahan pembangkit baru atau pembangunan T/L 150 KV dan GI baru. Dengan memperhatikan data beban pada malam hari yang mencapai 13,378 MW dan dengan daya mampu pembangkit 15,090 MW, maka sistim ABDASEL hanya mempunyai cadangan daya yang kecil, yaitu 17,12 MW, ini berarti kurang dari 12%, sehingga perlu adanya tambahan daya pembangkit. Rencana PLTM Kr. Jambopapeun terletak di Desa Lhok Pawoh, Kecamatan Sawang, Kabupaten Aceh Selatan, Provinsi Aceh dengan memanfaatkan aliran dan tinggi jatuh yang terdapat pada DAS Krueng Jambopapeun. Pada tahap studi awal, PLTM Kr Jambopapeun memiliki debit rancangan 11,87 m³/s, tinggi jatuh efektif 107 m, kapasitas terpasang 10,8 MW dan kapasitas listrik dapat terjual 71,195 MWh/thn Dengan masuknya PLTM Jambopapen (10MW) dan PLTM Jambopapeun (10MW), diharapkan dapat menambah cadangan daya hingga 54%, yang cukup untuk mengantisipasi pertumbuhan kelistrikan yang diperkirakan 6% per tahun hingga 7 tahun kedepan, dengan asumsi bahwa kondisi pembangkit yang ada tetap beroperasi, serta cadangan dapat dipertahankan 30%.

Disease transmission is often caused by viruses or bacteria contained in salivary droplets. Salivary droplets are produced from breathing, coughing, and sneezing activities. The extent of droplet dispersal can determine the safe distance between individuals when interacting, many studies have taken a simulation and modeling approach, arguing that the risk of exposure to pathogens. In this study, we attempted to set up an instrument to experimentally observe the flow of saliva droplets emitted during sneezing using a High-Speed Camera (HSC) model Phantom T-1340 without using a light sheet. Additionally, this study did not use lasers for the comfort and safety of individuals during recording of sneezing phenomena. The observation results explain that the sneezing phenomenon occurs within a time frame of 300 ms. The number of droplets observed was 246 with an observation probability of only 66%. The saliva fluid emitted is considered as large particles (bulk droplets) that undergo refraction due to two main factors, namely external and internal factors. External factors are influenced by environmental air flow rate, humidity, and temperature. Internal factors refer to the contents present in saliva such as water, protein, enzymes, and mucus or mucin.

The energy consumption of the world building sector reaches 30% of overall energy consumption and accounts for one third of greenhouse gas emissions worldwide. Thermal energy storage is a simple and effective technique to be applied to buildings to improve building energy efficiency, and is expected to reduce the environmental impacts associated with energy use. Thermal storage by utilizing phase change material (PCM) is the most promising technique because of its high energy storage capability and small temperature changes. The combination of building materials and PCM is an efficient way to increase the thermal energy storage capacity of building components for the purpose of storing thermal energy directly in buildings. In this study the results of testing the use of beeswax as a phase change material in building concrete are given. The test results of concrete equipped with beeswax as PCM decreased the strength of the concrete but on the other hand it was able to absorb and store heat energy. The results of application analysis in buildings are able to reduce indoor cooling loads.

The heat pipe (HP) is a fundamental heat transfer component frequently utilized for energy recovery in heating, ventilation, and air conditioning (HVAC). However, a heat pipe transmits heat from the hot side (evaporator) to the cold side (condenser), resulting in a temperature difference on both sides. There are numerous methods for measuring heat pipe performance. Using the temperature difference between the evaporator and condenser, the performance characteristics may be evaluated. The objective of this study is to compare the thermal performance of thermosiphon and commercial wick heat pipes (WHP) utilizing water as the working fluid and varying temperatures between the evaporator and condenser. The copper thermosiphon and commercial wick heat pipe had a diameter of 10 mm, a length of 800 mm, and a vacuum pressure of 5000 Pa. The filling ratios range between 30% and 50%, and it was evacuated at a pressure of 5000 Pa; the hot water temperatures at the evaporator were 30, 50, 70, and 90 ºC. Temperature was steadily increased every 30 minutes, and variations were observed at multiple places, including hot water, evaporator, and condenser wall. The average difference in temperature between the WHP and thermosiphon was around 0.6 degrees Celsius. The decreased temperature difference (T) indicates that the heat pipe is performing well. In addition, if the temperature difference is very great, the HP will dry up, therefore the WHP performs better than the thermosiphon.
