Posyandu is a health service unit that provides various basic health services for the community. Posyandu is also the first place that people at the village or sub-district level can visit to get basic health services, especially for pregnant women and toddlers. One important part of implementing posyandu is recording. Data recording has an important role in health monitoring, making reports an…
In this modern era, it cannot be denied that cellular networks are needed as a medium for exchanging information. However, despite these needs, there is still a lack of technological infrastructure. One of the areas where the cellular network is not yet optimal is the Griya Bina Widya housing complex which is located in the city of Pekanbaru, Riau province. Therefore, it is necessary to design …
Rice is the staple food source of Indonesian society to this day. To produce rice, a long process is required after harvest. One of the most important stages of the post- harvest process is drying the rice grain. Based on this, in this research a tool was designed that can dry rice automatically in order to facilitate the drying process of rice grain. This tool uses a DHT22 sonor as a temperatu…
The PLTS Pertamina RU II Dumai Solar Power Plant has a capacity of 2 MW, featuring an on-grid system comprising 16 homogeneous arrays. In this research, a PLTS system simulation developed based on existing technical data from the PLTS Pertamina RU II Dumai. The PLTS system, created using Simulink in MATLAB software, consists of a single array system, with 8 sub-arrays. Each subarray is made up …
This research aims to evaluate the performance of the Load Shedding system at Pertamina RU II Dumai using simulation methods with Simulink Matlab software. In the testing phase, four main cases were explored, each divided into four scenarios covering all possible generator operation scenarios. The test results indicate that in Case 1, Load Shedding is not required as the power loss can be handl…
Induction motors are the most widely used driving components in the industrial world. One company that uses induction motors to drive its machines is PT. Riau Mainstay Pulp and Paper. In this research, we discuss the influence of electric motor parameters due to changes in frequency. Therefore, changing the frequency to lower or higher will greatly influence other electric motor parameters such…

Graphene has several advantages including high thermal conductivity which is able to conduct heat between materials and optimize energy transfer of 5000W/mK, has high electrical conductivity, good optical transparenc…
Plasma is an electrical phenomenon that occurs when air (gas) fails to function as an insulator due to a high electric potential at the electrode (conductor) tips. This leads to ionization processes forming an electrical path (dielectric thread) connecting the two electrodes. Plasma can be utilized for various applications such as cutting, welding, and synthesis. The aim of this research is to …
Candlenut (Aleurites Moluccana) is a tropical plant that grows in the Euphorbiaceae family and has a natural distribution in tropical regions. Before being converted into graphene, candle nut shells undergo a carbonization process, producing charcoal as a raw material. Candlenut charcoal has a high carbon content, making it a suitable raw material for testing conversion to graphene. Graphene is…
