Abstract

The limited use of media in mathematics learning becomes one of the reasons we develop this research. Therefore, this research aim is to produce learning media in the form of mobile applications on Android or smartphones using Smart App Creator (SAC). As subject of research, students at SMP Negeri 1 Pinogaluman in grades VIIA and VIIB was carried out. The method used in this research is Research and Development (R&D) with modifications to the development stages of the ADDIE development model (Analyze, Design, Development, Implementation, Evaluation). The feasibility of learning media is seen from three aspects, namely validity, practicality and effectiveness. Data collection techniques use interview instruments, observation, expert validation questionnaires, questionnaires and student responses, and test results. The product trial was conducted in two stages, namely a small-scale trial with research subjects of 5 students of class VIIB students and a large-scale trial with research subjects of 46 students of class VIIA and VIIB. The validity criteria for innovative learning media were obtained from the assessment of media experts and material experts with average scores of 4.30 and 4.40 (very feasible category). The product was given a practical value based on student responses with an average score of 91.53%, and an average teacher response of 94.49%. Innovative learning media is also considered effective based on test results with a one group pretest and posttest experimental design with an average pretest score of 54.57 and an average posttest score of 82.83

Abstract

This study examines whether the mathematical communitical skills of studens taught with the gallery walk cooperative learning model are effective, reviewed from the self-confidence of students in grade VII at SMP Negeri 1 Botupingge. This Quasi Experiment research implements the treatment by level 2 x 2 design with a two-track analysis test and a Tukey test. The results obtain that the mathematical communication skills of students with high self-confidence in gallery walk cooperative learning are 79.86, and student with low self-confidence in direct learning are only 64.29. it can also be proven through tests with a significant level of 5% and df=33 showing tcount > tcount, 3.485, α=0.05, and ttable=2.042. in conclusion, the mathematics communication skills of student with high self=confidence that are taught by gallery walk cooperative learning are higher and more effective than students with low self-confidence that are taught by direct learning.

Abstract

Salah satu kabupaten di Provinsi Sulawesi Selatan yang memiliki wilayah pesisir adalah Kabupaten Jeneponto. Bagi masyarakat Jeneponto, wilayah pesisir ini memiliki arti penting tidak hanya karena kekayaan keanekaragamannya namun juga karena aktivitas ekonominya, termasuk perikanan, budidaya rumput laut, dan rekreasi. Namun saat ini erosi pantai di Kabupaten Jeneponto sudah sangat parah. Sistem alam akan memburuk jika pencegahan abrasi air laut tidak dilakukan, sehingga mengubah garis pantai dalam prosesnya. Tujuan dari penelitian ini adalah untuk mengevaluasi rancangan bangunan keselamatan pantai yang akan dimanfaatkan di Pantai Tamarunang dan mencari alternatif penanggulangan yang akan dibangun. Proses analisis melibatkan pemilihan bangunan pengaman pantai pengganti dan perhitungan desainnya. Tembok laut atau penyangga beton heksagonal merupakan perlakuan dengan titik terbanyak menurut matriks yang digunakan dalam penelitian ini untuk memilih alternatif konstruksi keselamatan pantai. Namun dalam memilih perawatan pantai, perlu kembali mempertimbangkan berbagai kondisi di sepanjang pantai Tamarunang. Dari segi kesediaan masyarakat, selama tindakan pengamanan tidak menghalangi arus perahu yang membawa nelayan dan petani rumput laut, maka masyarakat boleh saja diberikan perlindungan di sepanjang pantai Tamarunang. Berdasarkan hasil penelitian, dapat diambil kesimpulan sebagai berikut: 1. Ketinggian tembok laut adalah 2,44 meter; 2. Batu yang digunakan untuk tembok laut memiliki berat 27 kg; dan 3. Diameter batu tersebut adalah 27 cm. Kata kunci: Pesisir, Abrasi, Buis Beton Segi Enam

Abstract

The purpose of this research is to identify the physical characteristics of the Suwawa High House and the Bele Li Tauda'a House. The research method uses descriptive qualitative with locations in Kab. Bone Bolango and Gorontalo District. Field surveys were carried out in April – May 2023, starting with initial data collection followed by semi-structured interviews, field observations then data structuring, as well as confirmation of data with realities on the ground and the views of traditional leaders. The results showed that the physical characteristics of both were the same on the roof, the top part was triangular in shape with a second layer in the middle of the roof of the building.

Abstract

Driver behavior is the most dominant factor in accidents. Almost all accidents are preceded by violations of traffic signs. Through previous accident data, important and useful information can be known. The study aims to analyze two-wheeled motorbike riding behavior using Naturalistic Driving Study (NDS) and determine the influence of age and behavior of 150cc motorbike riders. Data taken from recordings taken by respondents and questionnaires. The results of the regression test to determine differences in age on motorbike rider behavior with a constant value of a = 196.03 show that this figure is a constant number which means that, if it does not involve age (X), the value of riding behavior (Y) is -5, 3956x. The regression coefficient is -5.3945. This figure is minus (-), which means that age (X) has a negative effect on driving behavior (Y).

Abstract

Bamboo is a plant that can be found around us, especially in rural areas. Bamboo is an environmentally friendly building material compared to conventional building materials. In addition to being easily accessible, cheap, and lightweight, bamboo also possesses considerable strength. There have been numerous studies on the use of bamboo, but in this research, bamboo is utilized as a substitute material for coarse aggregates. The planned compressive strength is for concrete with a compressive strength of K250 (20.75MPa) with substitution proportions of 30%, 50%, and 100%, which will be compared with normal concrete. In this study, it is expected to determine the proportion of substitution of coarse aggregates in concrete using bamboo. Based on the tests conducted, ranging from testing concrete-forming materials to compressive strength tests, the compressive strength obtained for normal concrete (0%) at 28 days is 26 MPa. Meanwhile, the compressive strength for concrete with a 30% substitution proportion is 26 MPa, 50% proportion is 13 MPa, and 100% proportion is 9 MPa. Thus, it can be concluded that the greater the percentage of concrete substitution, the lower the compressive strength obtained.
