Writing can be said as an activity that forms symbols. But writing is more than producing graphic symbols, just as speaking is defined not only as the production of sound. These symbols must be arranged, according to certain conventions, to form words and words arranged to form sentences. The ability to write is not an ability that can be obtained automatically. The aim of teaching Arabic-Malay writing is to recognize, train, and develop the ability to understand and carry out how to read and write properly and correctly according to Arabic-Malay regulations, as well as express simple ideas or impressions orally and in writing. In conducting this research the authors used a type of quantitative research. In this study the data collection method was carried out by testing the ability to write Malay Arabic words in the questionnaire given. After conducting research on the ability to write Malay Arabic words for students in grade 4a at SD Negeri 148 Pekanbaru, it was found that the students in grade 4a at SD Negeri 148 Pekanbaru as a whole had the ability to write Malay Arabic words in the low category with a percentage of 18.62%.

This research was conducted at SMK Widya Praja Ungaran. Every year the Widya Praja Ungaran Vocational School holds a New Student Registration (PPDB) to select prospective students. In the 2018/2019 academic year, 396 people registered and 298 people were accepted. The PPDB process starts from prospective students filling out the registration form and ends with the payment of re-registration funds for accepted students. The system used in the implementation of PPDB is still paper-based so that the performance of the PPDB committee is less effective. The purpose of this study is to design a computer-based new student registration system that is structured in a database to assist the PPDB committee in processing registration participant data, reduce paper purchase costs, minimize the risk of data loss, data corruption, recording and counting errors. Data collection was obtained through observation, interviews, questionnaires and literature study. This system is made using dynamic web with PHP (Hypertext Preprocessor) programming language and MySQL database. The design of this system uses UML (Unified Modeling Language). The development method used is the R&D (Research and Development) method. This study resulted in a cash-based new student registration administration system using a dynamic web to provide convenience for the committee in processing PPDB participant data from the registration process to new student re-registration transactions, as well as presenting reports quickly and accurately. Based on the research conducted, the results obtained from testing the validity of the new system score from internal and external validators. The internal validator with 20 statements obtained a feasibility percentage of 94%. An external validator with 20 statements obtained a feasibility percentage of 97%. From the results of these tests, it can be concluded that the administrative system for registering new students can be a solution to the problems found and can be implemented in the object of research.

Soil in a construction must have a high soil density value, a high soil density value affects the carrying capacity of the soil in carrying the load on it. dynamic cone penetration test / DCP (Dynamic Cone Penetrometer) is often performed. To get the CBR value, the DCP test results are correlated with a DCP-CBR Value Correlation formula. However, to anticipate deficiencies in the CBR-DCP correlation test, it is necessary to correct it with the DCP-CBR Correlation Formula from the Ministry of Public Works and Housing which is generally accepted for all regions of Indonesia. This research was conducted by conducting DCP tests at 8 points in the field and then taking soil samples which would then be taken to the laboratory to test the physical properties of the soil. After all the data has been obtained, then analyze and formulate the DCP – CBR correlation formula and compare it with the correlation formula. After doing the research, it is found that the DCP – CBR correlation formula model studied has the formula Log CBR = 3.2322 – 1.512 Log DCP, where this formula is generally in accordance with the DCP – CBR correlation formula from the Ministry of Public Works because of the position of the curve. slightly above the curve of the DCP-CBR Correlation formula of the Ministry of PUPR
