Abstract

 Abstract— The use of technology during the COVID-19 pandemic is very useful, none other than in service transaction activities.With this technology, it can help service actors and buyers in conducting service transactions. Services in Teguhan Village were previously still classified as manual, In the transaction process which is still classified as manual, the buyer must go to the service center and queue. Based on the results of interviews and observations with service actors and buyers, There are several problems experienced during the Covid-19 pandemic, and the problems experienced include the difficulty of service actors in getting consumers due to the covid-19 pandemic buyers are reluctant to go to the service place because they have to queue In the constraints experienced by the Bersinar UMKM, it can be concluded that in an effort to support the community service business of Teguhan Village,it is necessary media information system in the form of system design. Therefore, the author will design an information system design for offering various services based on E-commerce where service actors can offer a variety of services that offered to consumers and so that consumers can make transactions online to avoid queues.

Abstract

The decision tree method is built using data with variable input, rapot value, gender, and age of SMKN 1 Donorojo learners with label corners. Furthermore, the concept of C4.5 algorithm became one of the techniques in the formation of decision trees. In the procedure, the selection of attributes as a branch in the C4.5 algorithm uses the calculation results of the gain ratio. Based on the concept of calculations designed, the C4.5 algorithm is used in building decision trees in providing recommendations for learners at the college level. This research will qualitatively analyze the implementation of the decision tree method in determining student direction by using the C4.5 algorithm of data mining in the form of a gain ratio of rapot values, interests and talents of students. From the results of the C4.5 decision tree algorithm test can make more accurate predictions in the research of the management of majors and major recommendations for learners. The existence of these methods is expected to be able to provide solutions for students and schools concerned in determining the appropriate majors for students to pursue to the opportunity for success and improve the ability to study in college. C4.5 algorithm itself uses an induction approach where in this approach, the C4.5 algorithm. Divide data based on the criteria selected to create a decision tree.Keywords—: Decision tree, direction determination, C4.5 algorithm

Abstract

Salah satu inovasi game technology yang akan digunakan dalam membangun media pembelajaran biologi tentang mata sebagai penunjang kegiatan belajar mengajar siswa adalah Augmented Reality(AR), yaitu penggabungan dunia nyata dengan dunia maya, dimana objek virtual overlayed pada dunia nyata. Dari segi teknis, teknologi Augmented Reality merupakan teknologi transformatif, demana sistem intraksi melikupi keseluruhan lingkungan di luar tampilan layar. Dari segi strategis, pemanfaatan media pembelajaran berbasis Augmented Reality sangat berpengaruh dalam peningkatan minat belajra siswa untuk mengetahui dan memahami tentang mata melalui visual 3D. Dalam aplikasi ini terdapat objek mata 3 dimensi yang dibuat dengan menggunakan aplikasi Blender, dengan Unity sebagai game engine dan Vuforia sebagai library. Cara menggunakanya dengan mengarahkan kamera pada marker yang telah tersedia. Kemudian akan muncul gambar 3 dimensi pada layar smartphone beserta penjelasannya. Media pembelajaran biologi tentang mata dengan menggunakan Augmented Reality lebih mudah dipahami dari pada menggunakan gambar 2 dimensi. Karena siswa dapat melihat bentuk bola mata secara nyata dalam bentuk 3 dimensi.

Abstract

Dewasa ini halaman web merupakan salah satu media informasi modern yang berkembang pesat. Halaman web dibuat tidak hanya dari sisi desain dan informasi apa saja yang bisa disajikan, akan tetapi harus melihat dari aspek keamanannya juga. Karena keamanan halaman web merupakan hal yang sangat penting, jebutuhan tentang keamanan halaman web muncul untuk melindungi data dan informasi yang ada didalamnya. Metode yang digunakan untuk pengujian keamanan halaman web ini menggunakan tools yang berupa perangkat lunak dan dengan cara-cara tertentu untuk menguji keamanan halaman web. Sedangkan untuk melakukan analisis keamanannya juga digunakan tools yang serupa. Dengan demikian target khusus pada penelitian ini adalah seberapa rentan halaman web dari Program Studi DIV Teknik Informatika Politeknik Harapan Bersama dan dengan cara apa sajakah yang memungkinkan untuk menutup celah keamanan tersebut.

Abstract

Abstract— Pandanus fiber and teak sawdust were waste products that were abundant in availability, but have not been used optimally. Base pandanus fiber and teak sawdust were used as alternative reinforcement for composite materials. The purpose of this study was to test the tensile strength and water absorption of composites reinforced with base pandan fiber and teak sawdust with polyester resin as a matrix. This composite was made by hand lay up technique with variations in the volume fraction of coconut fiber fibers of 10%, 20%, 30%, 30%, 20%, 10% teak sawdust, 60% polyester resin with random fiber orientation, 30 mm fiber length. Composite specimens were cut according to ASTM D 638-01 standards for tensile testing and ASTM D 570 for water absorption tests. The results of this study were tensile strength, strain, modulus of elasticity with optimum strength respectively 30.28 MPa (volume fraction 30%; 10%; 60%), 1.508 mm / mm (volume fraction 10%; 30%; 60%) , 447.46 Mpa (volume fraction 10%; 30%; 60%). Water absorption was 2.07% (volume fraction 10%; 30; 60%).

Abstract

Vaccination is one of the policies taken by the Indonesia government to control the Covid-19 pandemic. Vaccination is expected to form community immunity to prevent the spread of Covid-19. This policy taken by the government has generated various responses from the public in the form of opinions posted on social media platforms, one of which is on the Youtube. In order to better understand public sentiment towards this vaccination policy, it is necessary to analyze the opinions given. The Support Vector Machine (SVM) algorithm used in this study to classify public sentiment on vaccination policy. The data sources used are comments posted on Youtube videos regarding Covid-19 vaccinations. Three scenarios were used in the test with variations in the ratio of the testing data and training data of 90:10, 80:20, and 70:30 with 10 tests on each variation of the data ratio. Based on the tests carried out, the results obtained accuracy of 86%, 85%, and 84%.

Abstract

In this era, infrastructure development in Indonesia continues. This continues to be pursued to facilitate community activities in various fields. Some of the infrastructure that continues to be built include toll roads and buildings. One of the most important materials for building infrastructure is concrete. Concrete also has various types, including normal concrete and HVFA-SCC. In this study, the two types of concrete will be compared and tested for compressive strength against the age of the concrete. The test were be done at 7 days, 14 days, 21 days, 28 days, and 90 days. The research step starts from preparing materials, conducting material testing, making job mix formulas, making test objects, testing compressive strength, and getting results. The obtained results shown that the fresh concrete of HVFA-SCC has met the self-compacting concrete according to the Slump flow test, L-Box test, and the V-Funnel test. Based on the compressive strength test, the results show that the age of the concrete has an influence on the compressive strength.
