Abstract

A tourist in determining the purpose of his tour, must be based on several criteria that are used as a determining factor in choosing. These criteria are taken into consideration by tourists in determining which tourist attractions will be chosen. Thus this study aims to assist tourists in choosing tourist attractions in North Sumatra based on the desired criteria and / or provide information to tourists about the best tourist attractions in North Sumatra in accordance with the desired criteria. The Elimination Et Choix Traduisant La Realita (ELECTRE) method which is a system that uses a multicriter decision making method based on the outranking concept by using a pairwise comparison of alternatives based on each appropriate criterion. This research resulted in a recommendation for natural tourist attractions in North Sumatra, namely Teluk Dalam tourism in the Nias Islands.

Abstract

The current large image storage capacity is increasingly important. This need, caused by the image to be stored more and more. Digital image processing in the field of image decomposition can be a solution to minimize memory needs in representing digital images. In this case the ratio in the decomposition process becomes the reference comparison between the decomposed image with the original image. In this research decomposition process using DWT algorithm. The image decomposition based discrete wavelet transform using the calculation system with the decomposition with the direction of the row and decomposition with the direction of the column. The decomposition process uses a leveling and subtraction formula by calculating the average value of two pairs of data. The results of this study indicate that the decomposition of digital images based on discrete wavelet transform is expected to be one useful algorithm in imaging technology for digital image decomposition. Keywords: digital image, decomposition, discrete wavelet transform

Abstract

Kertas pada umum merupakan bahan yang tipis dan rata yang biasanya terbuat dari kayu dengan kadar serat selulosa 39%. Maka dapat diprediksikan bahwa akan terjadi eksploitasi hutan secara besar-besaran yang dapat mengakibatkan terganggunya kestabilan lingkungan sehingga perlu mendapat perhatian khusus dan mencari alternatif dengan bahan lain. Bahan alternatif yang dapat digunakan antara lain jerami, ampas tebu, merang ,pelepah pohon pisang, batang keladi, batang genjer. Pada pembuatan kertas, penambahan larutan NaOH atau CaO, berfungsi untuk melarutkan lignin saat proses pembuburan (pulping) sehingga mempercepat proses pemisahan dan pemutusan serat. Penelitian ini bertujuan 1). Untuk mengetahui ketahanan tarik dan ketahanan sobek kertas dari batang genjer melalui Chemical Pulping (proses Kimia) dengan menggunakan NaOH dan CaO yang berbeda.2). Untuk mengetahui uji sensoris kertas dari Batang Genjer dan batang keladi melalui Chemical Pulping (proses Kimia) dengan menggunakan NaOH dan CaO.Penelitian dilakukan di Lab.

Abstract

This study aims to find out how the application and effectiveness of schoology learning media during the Covid-19 pandemic on biology learning outcomes at MTS Al-Wasliyah Tembung. This research is a qualitative research using case study method. The subjects of this study were the vice principal, teachers of science studies, and 85 students of class IX science at MTS Al-Wasliyah Tembung. The instrument used to collect data was by interviewing the vice principal and biology teachers. While the students used a questionnaire for class IX science students as many as 15 items and the results of learning biology on genetic material. Based on the results of this study, it was found from interview data, questionnaires and grades obtained by students in science subjects, especially in genetic material, which was above the KKM with a value of 70, where class IX-3 consisted of 40 students with an average value of 75.75 and class IX-3 IX-5, which consists of 45 students with an average score of 77.22 and the effectiveness of the use of schoology conducted by MTS Al-Wasliyah Tembung during the covid-19 pandemic is 72% and has been running effectively. While the inhibiting factor for learning schoology during the covid-19 pandemic was because students did not have android phones which had an impact on students' delays in joining classes. In addition, the internet network and data packages are also a problem for students at MTS Al-Wasliyah Tembung.

Abstract

The project based learning (PJBL) model is defined as an innovative model that is critically multistrategic basically for understudy progress in creating current 21 century abilities. The purpose of the study was to determine the influence of student learning outcomes on mushroom material by applying an entrepreneurship-based learning model (PJBL) first grade (X class) of Senior High School SMA Negeri 1 Aek Songsongan for the 2021/2022 academic year. Type of research with quantitative by True-ekperimental with the from of pre-test post-test control group design. Review test comprised of experimental class X MIA3 and control class X MIA4  selected by cluster random sampling. The research instrument uses diagnostic tests through multiple choice tests and student response questionnaires. Data analysis methods utilizing the assistance of IBM SPSS 24 and Microsoft Excel 2013. The calculation of the hypothesis test results, based on the significance level of α= 0.05 obtained a tcount 6,830 and a ttable value of 1,669. Cause tcount > ttabel, then H0 is dismissed and Ha is acknowledged. Then it can be interpreted by this, is a significant influence of the entrepreneurship based project based learning (PJBL) learning model on the learning outcomes of class X students on Mushroom material. With a typical score got by the control class of 45.15 and experimental class of 62.52 with the achievement of the maximum score of the control class 60 and the experimental class 83.
