This will certainly have an impact on the success of HF radio communication which is very dependent on the ionosphere layer. One of the impacts of solar activity is the variation in the ionosphere layer which has an 11-year cycle phase causing changes in the value of foF2. This study aims to analyze the measurement data of the ionospheric layer (ionosonda) to see the effect of the half cycle of solar activity for the period 2010 to 2015 which can be used for the Pekanbaru area, Indonesia with Near Vertical Incidence Skywave (NVIS) propagation mode. The results of the study indicate that there are differences in the use of working frequencies for each year that can be used between 2 MHz to 10 MHz, with the right communication time at 08.00 UTC+7 to 22.00 UTC+7. The change in the highest frequency value is caused by positive storms and negative storms that occur in the ionosphere layer which will interfere with high frequency radio communications and satellite-based navigation

However, there are some shortcomings in running the e-rapor application, such as a small server capacity so that the website is difficult to access, Random basic competencies make teachers time consuming in processing student grades, teachers cannot print student report cards if the automatic description of the system exceeds the description limit, admin cannot delete classes, e-rapors are not well integrated with DAPODIK(Education Principal Data) and there are no researchers who lead or lead to aspects of convenience, benefits and acceptance of the E-rapor information system. This study aims to analyze and determine the effect of the usability, benefits and perceptions of user convenience on the acceptance of web-based E-rapors at Asshofa Islamic High School Pekanbaru using the TAM method. The three variables used in this study are the perception of convenience and the perception of benefits on the perception of user acceptance. The sample in this study were 37 respondents. The results in this study indicate that if the convenience factor has a significant effect on user acceptance of web-based Erapors, then the benefit factor has a significant effect on acceptance of user acceptance of the E-rapor system and the convenience and benefits factors together affect the acceptance of E-rapors. This shows that if the convenience and benefits factors increase, the user acceptance of information technology or information systems will increase.

Material is the main thing in the smooth process of work at PT. PLN (Persero) Rayon Bangkinang that needs to be considered in the company's warehouse. The problem faced by this company is that the operator has difficulty in carrying out the activities of searching, importing, and releasing materials and leveling the material randomly placed (Random Storage) which makes it difficult for warehouse activities. In solving the problems faced by the company, the Class Based Storage method is used in designing the arrangement of new materials according to class and category by utilizing warehouse space owned by the company. Based on the results of calculations using Warehouse Slotting, there are 156 slots and 24 rows of shelves needed and the material is divided into 3 subgroups. Material classification uses a Pareto diagram to determine 2 material flows, Fast and Slow. Another suggestion in this study is the use of a shelf that has 7 levels of storage as a storage medium and has a shelf label to facilitate the search process.

Garbage management operations generally collect garbage from the source of the garbage generation and then transport it to a landfill. Starting from garbage collection on the streets, garbage collection at public facilities, at each point of the temporary disposal site and then transported by truck or garbage collection vehicle to the final disposal site. The problem of route for transporting garbage is a problem with the Vehicle Routing Problem (VRP), namely the problem of finding a route with minimal costs from one disposal site to another site which is scattered with different quantities of garbage. NN-SOS is believed to be able to make a good contribution to the metaheuristic algorithm By integrating NN and SOS, it is hoped that it will be able to improve the performance of local search which is more effective and the results are stable (steady state) in achieving values that resemble global optimal. It is proven that the total distance generated by the NN-SOS algorithm is 61,34 kilometers, while the total distance traveled in real conditions is 68 kilometers. Then this algorithm is able to provide a solution with a very fast average computation time of 11,9 seconds.

Perkembangan teknologi yang begitu cepat memaksa kita untuk dapat mengambil keputusan dengan cepat pula. Kredit macet menjadi salah satu resiko terbesar lembaga keuangan. Resiko kredit macet ini wajib diminimalisir dengan menganalisa faktor status nasabah berdasarkan data personalnya, sehingga dapat dilakukan klasifikasi berdasarkan hubungan antar faktor tersebut. Salah satu kunci utama memenangkan persaingan pasar yaitu dengan menentukan target pasar. Data mining menyediakan banyak alat bantu untuk klasifikasi, salah satunya dengan menggunakan metode analisis CHAID (Chi-square Automatic Interaction Detection Analysis). Diagram pohon keputusan yang dihasilan dari Analisis CHAID dapat memberikan informasi tentang derajat hubungan antara variable independent dan dependent, serta informasi tentang karakteristik masing-masing kategori.
