Abstract

This study aims to determine and obtain the amount of APP / TMA Palembang airspace capacity after RNAV-1 is applied. This research was carried out at the LPPNPI Public Corporation Palembang Branch in March to April 2019. The method used in this research is the quantitative method. Data collection techniques used are structured observations with the results of the data obtained in the form of the amount of traffic and the total workload of ATC for one hour during peak hours, and literature studies that contain data on the calculation of airspace capacity before the application of RNAV-1 and monthly traffic data. The analysis technique used is to use parametric statistics with the SPSS application in the form of a simple linear regression between the amount of traffic and the total workload of ATC to get the results of airspace capacity after the application of RNAV-1. Before the application of RNAV-1 the airspace capacity had been calculated by the ATFM unit with the result that the airspace capacity in one hour was 16 traffic / hour. After research and analysis, after the application of RNAV-1 there was an increase in the amount of airspace APP / TMA Palembang to 18 traffic / hour. The increase in airspace capacity after the application of RNAV-1 is 12.5%. With these results, the application of RNAV-1 needs continuous implementation.

Abstract

Abstract Back-calculation is a method of analyzing the material properties of a pavement, which is supported by field testing in the form of Non-Destructive Testing using the Falling Weight Deflectometer. Analysis of the material properties gives the value of the modulus of elasticity, with the input data in the form of deflection of the results of the Falling Weight Deflectometer test. The back calculation in this study was carried out with the support of the ELMOD 6.0 computer program, and resulted in the root means square and backcalculated moduli values. As a case study, the Janti (Yogyakarta)-Prambanan (Central Java Province Boundary) road section was selected. The results obtained indicate that the modulus of elasticity in the north section for the Hot Mix Asphalt layer is 1401.31 MPa, for the base layer is 597.75 MPa, for the subbase layer is 116.79 MPa, and for the subgrade layer is 96.15 MPa. While in the south section, the modulus of elasticity for the Hot Mix Asphalt layer, base layer, subbase layer, and subgrade layer are 976.80 MPa, 128.22 MPa, 104.59 MPa, and 75.68 MPa, respectively. Keywords: back-calculation; road pavement; material properties; deflection; modulus of elasticity Abstrak Perhitungan balik merupakan suatu metode analisis material properties suatu perkerasan jalan, yang didukung dengan pengujian lapangan berupa Non-Destructive Testing menggunakan alat Falling Weight Deflectometer. Analisis terhadap material properties memberikan nilai modulus elastisitas, dengan input data berupa lendutan hasil pengujian Falling Weight Deflectometer. Perhitungan balik pada studi ini dilakukan dengan bantuan program komputer ELMOD 6.0, dan menghasilkan nilai root means square dan backcalculated moduli. Sebagai studi kasus dipilih ruas Jalan Janti (Yogyakarta)-Prambanan (Batas Provinsi Jawa Tengah). Hasil yang diperoleh menunjukkan bahwa nilai modulus elastisitas pada ruas utara untuk lapis Hot Mix Asphalt sebesar 1401,31MPa, untuk lapis base sebesar 597,75 MPa, untuk lapis subbase sebesar 116,79 MPa, dan untuk lapis subgrade sebesar 96,15 MPa. Sedangkan pada ruas selatan, nilai modulus elastisitas pada lapis Hot Mix Asphalt, lapis base, lapis subbase, dan lapis subgrade berturut-turut adalah 976,80 MPa, 128,22 MPa, 104,59 MPa, dan 75,68 MPa.

Abstract

Salah satu permasalahan yang muncul saat ini yaitu lunturnya pengetahuan mengenai budaya terutama pada kalangan Generasi Alpha. Dengan demikian, perlu dirancang sebuah media edukasi berupa aplikasi yang mampu menambah pengetahuan tentang matematika sekaligus mengenalkan budaya dengan memanfaatkan teknologi digital yang sudah sangat akrab di kalangan Generasi Alpha. Penelitian ini bertujuan untuk mengembangkan dan menghasilkan produk berupa media edukasi Blantik yang layak dan praktis sebagai upaya pencegahan erosi budaya di kalangan Generasi Alpha. Jenis penelitian menggunakan Research and Development (R&D) dengan model pengembangan ADDIE. Teknik pengumpulan data menggunakan instrumen validasi media serta angket respon guru dan siswa. Berdasarkan hasil validasi terhadap media edukasi Blantik dapat dikatakan layak untuk diujicobakan karena secara substansi, materi benar dan tidak terdapat kesalahan konsep, serta rata-rata yang diperoleh lebih dari 3,00. Kepraktisan media edukasi Blantik dapat dilihat berdasarkan data hasil angket respon siswa yaitu 82% dan guru yaitu 95%. Dengan demikian, disimpulkan bahwa aplikasi Blantik layak dan praktis untuk digunakan.   One of the problems that arise today is the fading of knowledge about culture, especially among the Alpha Generation. Thus, it is necessary to design educational media in the form of an application that can increase knowledge about mathematics while at the same time introducing culture by utilizing digital technology which is very familiar among the Alpha Generation. This research aims to develop and produce a product in the form of educational media Blantik that is appropriate and practical as an effort to prevent cultural erosion among Generation Alpha. This type of research uses Research and Development (R&D) with the ADDIE development model. Data collection techniques used media validation instruments and teacher and student response questionnaires. Based on the results of the validation of the educational media Blantik it can be said that it is feasible to be tested because in substance, the material is correct and there are no conceptual errors, and the average obtained is more than 3.00. The practicality of the educational media Blantik can be seen based on the data from the student response questionnaire, namely 82%, and teachers, namely 95%. Thus, it is concluded that the Blantik application is feasible and practical to use.

Abstract

This study discusses the interpersonal communication strategies used by religious teachers in conveying Islamic values ​​to students at TPQ Margoyoso Blangkon Mosque. The background of this study is based on the importance of the role of religious teachers as agents of change in shaping the character of students through an effective communication approach. The purpose of this study is to describe the interpersonal communication strategies applied and their influence on students' understanding of Islamic values. This study uses a descriptive qualitative approach with data collection techniques through observation, in-depth interviews, and documentation. The results of the study indicate that religious teachers apply communication strategies such as a personal approach, two-way dialogue, empathy, and role modeling. This strategy has proven effective in building emotional closeness and increasing students' understanding and practice of Islamic values. The implications of this finding indicate that the success of conveying Islamic values ​​does not only depend on the teaching materials, but also on the quality of interpersonal communication between teachers and students. Therefore, religious teachers need to continue to hone their communication skills to create an inspiring learning environment that touches the affective aspects of students.
