Abstract

The distribution system is an important part of the electrical energy distribution activities as directly connected to the customers. Therefore, the distribution system is always required to have good reliability. One of solution to increase reliability is using recloser in the medium voltage feeder.Optimal placement of recloser will be able to maximize reliability. In this researched, the author used a Ant Colony Optimizization method in determining the optimal position of recloser. Objective function is combining SAIFI and SAIDI. SAIFI and SAIDI are calculated using section technique method. Simulation calculations using MATLAB (Matrix Laboratory) programming. Program testing was carried out on the Gurami Feeder network at PT. PLN (Persero) ULP West City Pekanbaru Area which distributes electrical energy sourced from the Garuda Sakti Substation. Gurami feeder is a radial distribution network. Based on the application of the ACO method, the best position for placing the addition of a recloser on the main feeder before the distribution transformer is KB-0508 (100kVA). The addition of the recloser with the best position resulted in a reduction in the SAIDI value from the initial value of 16.647 hours/year to 14.040 hours/year and the SAIFI value from the initial value of 18.907 times/year to 15,928 times/year. Keywords: reliability, ant colony optimizazition, section technique, recloser.

Abstract

Pekanbaru City is the capital city of Riau province, where the majority of the population is Muslim. Therefore, the existence of a representative mosque as the main means of worship for Muslims is very necessary. In general, the number of mosques in Pekanbaru City is sufficient, this is proven by the fact that it is not difficult for immigrants to find mosques when they are going to worship. However, the existence of the existing mosque building is still seen as not being able to represent the vision of the city of Pekanbaru "The Realization of Pekanbaru as a Smart City Madani", where one of the missions is to Increase Human Resources (HR) who are Faithful, Independent, Resilient and Highly Competitive. To realize a place of worship or a mosque that fulfills the mission of the city of Pekanbaru, a mosque is designed with a futuristic architect approach. Futuristic architecture is an understanding of freedom in expressing or expressing ideas or ideas into an unusual, creative and innovative display form. The design of a mosque with a futuristic architectural concept related to technology requires a special design that refers to space requirements, the appearance of the building and the use of materials with today's technology. The construction of this mosque is expected to become an icon of Pekanbaru City to support the vision of the city that has been set by the Mayor of Pekanbaru.Keywords: Futuristic Architecture, Mosque, Pekanbaru City

Abstract

Mikrotik has the ability to improve network performance through the RouterOS device. Junior High School named Tunas Bangsa uses a router that has not been configured properly so it has an impact on poor network quality. This is evidenced by the results of the Quality of Service (QOS) measurement from a throughput parameter which is included in the "bad" category based on the TIPHON throughput standard.The solution to improve network performance is design bandwidth management using the Per Connection Queue (PCQ) method. The method is designed for network condition that have many clients where the distribution of bandwidth can be done evenly because PCQ has complexity in determining parameters by grouping based on source and destination traffic.After the configuration done, the QOS calculation is carried out again to prove that the network has gained significant changes. The results show that the throughput has increased based on the TIPHON standard, it is included in the "good" category. This is proof of success in managing bandwidth on the network.Keywords: Mikrotik RouterOS, Network Performance, Per Connection Queue (PCQ).

Abstract

Microplastics are one of the major threats to ecosystems in rivers. Microplastic is the smallest part of plastic measuring <5 mm which if it enters the environment it will accumulate in the waters and is not easily removed because of its persistent nature. The abundance of microplastics is strongly influenced by their activities and pollutant sources. The Sibam River is a tributary that empties into the Siak River. The high activity along the river and the presence of settlements are thought to be the distribution route for microplastics to the river. The purpose of this study was to determine the abundance and types of microplastics in the Sibam River, Pekanbaru Riau. The abundance of microplastics obtained was based on 3 segments, which ranged from 4.444-11,555 particles/kg dry sediment. The types of microplastics found in this study were fiber (15.38%), film (40.38%), and fragments (44.24%).Keywords: microplasty, abundance, sediment, Sibam River
