A traffic accident is an event that occurs in a traffic flow due to an error in the traffic shaping system that involves humans as drivers, vehicles, roads, and the surrounding environment. In this study, the road that was studied was Rantau Berangin - Ujung Batu which was a class III collector road with a length of ± 66.5 km. This study aims to determine the level of traffic accidents in the area to obtain the Accident Rate value on the Black Spot and Black site . The method in this research is a qualitative method to get the value of the Black Spot and Black Site based on the accident rate. The data used are primary and secondary data obtained from the Kampar Police from 2014 - 2018, as well as those related to traffic accidents. The results of analysis of the received data show that the rate of traffic accidents on roads Rantau Berangin - Ujung Batu is relatively high with 24 scenes of the accident, which roads rantau Berangin - Silam be the point most vulnerable areas of traffic accidents with Accident Rate of the Black Spot by 9,767 and the Accident Rate of the Black Site is 1,205. Meanwhile, the factors that cause traffic accidents on the Rantau Berangin - Ujung Batu road section are dominated by human factors themselves, such as driving at high speed in crowds and using other drivers' lanes.

The development of Information Technology (IT) is now very rapid and has been used in various aspects of life both in the field of government, banking, socio- cultural, industrial, education, and even health. One type of disease that gets attention for the application of IT is corona virus or better known as Covid 19 because the spread is quite widespread throughout the country, especially in the territory of Indonesia. Corona virus disease development in Indonesia is growing, based on WHO data as of today on August 30, 2020 positive cases have reached 172,053 people, cases died 7,343 people and recovered 124,185 people and the number of cases is increasing every day. Based on these conditions, Central Aceh is in a state of alert against the threat of corona virus. then a form of prevention  of the widespread spread of the virus can be done by breaking the chain of transmission by doing social distancing. In this study, a system will be designed to anticipate the Covid-19 pandemic by predicting the rate of spread of covid-19, especially in central Aceh districts using the Naive Bayes Classifier method. The accuracy level of this system is a positive case of 60%.

The use of sea sand in construction work from an economic point of view does have advantages. One of them is increasing the income of the sea sand collectors who are spread throughout the area in Fakfak Regency. In addition, the potential availability of sea sand is quite large and is able to accommodate all types of concrete construction work in this area. This study aims to determine and analyze the use of sea sand in the AC-WC mixture of course by doing the Marshall test. This study uses variations in asphalt content of 5.0%, 5.5%, 6.0%, 6.5% and 7.0%, this study was carried out using Marshall testing in accordance with the general specifications of Bina Marga 2018. The results of the research conducted showed a relationship asphalt content and Marshall parameters such as stability value, VMA, density, MQ at an asphalt content of 5.0%-7.0%, meet the specifications of 1932 kg, 19.84%, 2.26 gr/cm3 and 1031 kg/mm. Values of VIM, VFWA and flow at 5.5% asphalt content are known to not meet the mix spasticity, namely 8.07%, 59.71% and 1.67 mm. Based on the Marshall parameter data, the Optimum Asphalt Content value is 6.5%.

Vapors or e-cigarettes are cigarettes with an evaporation process. One shop selling vapor products called the Independent Store sells various kinds of vapor products as well as liquids and other vapor equipment. This Independent Store store has problems in selling because it has not used an online-based sales system. Therefore, it is the desire of the researchers to be able to assist in the process of selling vapor products at the Independent Store store by creating a website. In the process of creating a website for selling vapor products, method is used SDLC (System Development Life Cycle) the waterfall model . With the hope of helping shop owners and employees in the sales process.

Perkembangan bisnis saat ini yang sangat kompetitif dan berkembang pesat karena aktivitas aktivitas dalam pemenuhan kebutuhan hidup tidak terlepas pada sektor transportasi dalam pengiriman barang dan material. Semua penyedia jasa mulai beralih ke media E-commerce dan menggunakan internet untuk media pertukaran informasi dan komunikasi. Perusahaan di Indonesia yang menggunakan media E-commerce yaitu Go-Jek di mana memiliki 100 ribu cabang di 50 kota. peneliti ingin mengetahui tingkat pengaruh kualitas pelayanan pada jasa E-Commerce Go-Jek termasuk pelayanan pengirimannya terhadap keputusan pembelian masyarakat. Hasil uji regresi linier sederhana menyatakan bahwa semakin banyak penyedia layanan, yaitu Go-Food, yang memberikan kualitas layanan yang diharapkan, maka akan meningkatkan penjualan produk karena terdapat pengaruh yang cukup positif dan signifikan antara variabel  kualitas pelayanan Go-Food terhadap variabel keputusan pembelian.

In the process of distributing electricity from the generator to the consumer, it goes through many processes and passes through several parts. Starting from the electric power distribution system, one of which is the distribution system. Considering that the scope of this distribution network is directly related and is located in an inhabited area, in addition to meeting technical quality requirements, it must also meet the requirements for being safe for users and familiar with the environment. In this distribution system there is a very important equipment in distributing electric power, namely the distribution substation. Because of the important role of the distribution substation, it must be protected from disturbances that may occur. One of them is the load imbalance between phases. In practice and in reality, in various locations of electric power distribution, a completely balanced load condition is obtained, mainly because of the large number of single-phase load groups that are serviced by a low-voltage three-phase distribution system. This is because the characteristics and types of electrical power user equipment vary with different consumer conditions and activities. To obtain load balance, load balancing is carried out between phases for load distribution so that load adjustments occur at distribution substations.

Research has been carried out on the load imbalance analysis on the transformer with the aim of knowing the percentage of load imbalance on the transformer. From the results of the analysis that has been carried out, it is known that the percentage of transformer loading is unbalanced and is in bad condition because it exceeds the balance standard that has been set, which is above 25% with a percentage for line 1 of 60% during the day and 80% at night. While on line 2 has a percentage of 35% during the day and 33% during the day.

Antre merupakan kegiatan yang sangat erat kaitannya dengan kehidupan sehari-hari dan timbulnya antrian yang panjang akan mengakibatkan hilangnya pelanggan/ nasabah. Salah satu antrian yang dialami adalah antrian berobat dengan menggunakan asuransi BPJS Kesehatan di Puskesmas Margadadi Kabupaten Indramayu yang memiliki administrasi yang berbelit-belit. Pemodelan dan simulasi sistem digunakan untuk menganalisis antrian dalam sistem sehingga dapat diketahui alternatif perbaikan yang dilakukan. Berdasarkan output model sistem yang telah dibuat menggunakan software Promodel 7.5 dengan input sesuai dengan data pengamatan yang dikumpulkan dan beberapa hasil validasi data, maka dapat diketahui jumlah entitas yang masuk dan keluar tidaklah sama, yaitu 48 orang masuk dan 20 orang keluar. Ini menunjukkan terdapat antrian dalam sistem. Secara keseluruhan, sistem antrian BPJS Kesehatan pada penelitian ini cukup efektif karena aktivitas entitas lebih banyak dihasbiskan dal proses operasi. Namun, berdasarkan beban kerja yang dialami petugas administrasi dan dokter diperlukan penambahan jumlah petugas dan dokter.
