Abstract

Toraja carving is rich in mathematical concepts, especially geometric concepts, this is because in Toraja carving there are many geometric concepts such as squares, rectangles, triangles, and so on. This fact shows that the concepts of mathematics, especially geometry have been used by our ancestors since ancient times. The concept of geometry combined with Toraja local wisdom is expected to be able to facilitate learning geometry both in class and in college. Besides, it can be a means of preserving Toraja culture, especially for the younger generation of Toraja. The purpose of this research is to examine what geometric concepts are contained in Toraja carvings, as well as the meaning contained in them. This research was conducted in 3 (three) stages. Data were obtained using observation and interviews with 5 informants, namely those who understand the ins and outs of Toraja culture. From the research results, it is found that in Toraja carving, there are geometric concepts such as diagonals, parallel lines, symmetry, curved lines, squares, rectangles, trapezoid. Each carving has its own meaning and matches the name of each carving. The symbolic meaning in Torajan carvings generally describes the life of the Toraja people in relation to God, others, and their surroundings.

Abstract

Telah dilakukan pembuatanPrototype Pembangkit listrik Tenaga Hentakan Kendaraan di Jalan Raya” dengan tujuan umum memanfaatkan sumber EnergiBaru Terbarukan (EBT) sebagai pembangkit listrik. Salah satu sumber energi yang sangat melimpah dan belum banyak dimanfaatkan adalah energisentakan kendaraan. Tujuan khususnya adalah mendisain prototipepembangkit listrik tenaga hentakan kendaraan di jalan raya dimana listrik yang dihasilkan disimpan dalam baterai (accu). Tujuan Jangka Panjang adalahditemukannya alat konversi energy sentakan kendaraan di jalan raya dengan efisiensi maksimum sehingga dapat dijadikan pembangkit dan dapat menghasilkan daya cukup besar. Prototipe pembangkit listrik tenaga Hentakan kedaraan pada dasarnya sama dengan pembangkit listrik yang lain yang menggunakan dinamo. Pada prototype ini, gaya yang dimanfaatkan untuk memutar dinamo adalah dari sentakan kendaraan. Sebuah alat didesain untuk mengubah hentakan kendaraan menjadi energi rotasi yang akan memutar dinamo untuk mendapatkan arus listrik. Listrik yang diperoleh kemudian di simpan dalam baterai (accu). Dari prototype yang dihasilkan sebelum pemasangan dinamo pembangkit telah didapatkan putaran yang cukup tinggi untuk memutar dinamo untuk menghasilkan listrik. Setelah dinamo terpasang, putaran menjadi berkurang karena beban dari dinamo akantetapi putaranya masih cukup untuk mengaktifkan dinamo sebagai pembangkit. Indikator pembangkit telah berfungsi adalah matinya lampu indicator yang terpasang pada dinamo.

Abstract

One of the ways teachers design a learning environment is to use the right media in teaching a concept so that the concept is easily accepted and understood by students. Therefore, the author offers a solution to use the media or learning resources that exist in the environment of the students in this case ethnomathematics. There has been a lot of research from UKI Toraja that the culture of the Toraja people is rich in ethnomathematics. Therefore the author was inspired to use this in mathematics learning. In this study ethnomathematics will be packaged in student Worksheets. This is considered very appropriate because LKS, which contains instructions for the stages of solving a problem, will challenge students to solve it or find a concept in an interesting way because it uses media in Toraja culture, which is inseparable from the lives of students at SMP 1 Denpina or it can be said that the students are familiar with it. LKS which is based on Ethnomathematics, apart from being a learning medium that helps teachers convey messages to students, the use of ethnomathematics in learning is one way to maintain the local wisdom of the Toraja people so that the younger generation who are currently in the digital era still understand and even maintain the culture they have. This study aims to apply ethnomathematics-based student worksheets in mathematics learning in Schools. The research method used is a quantitative research method. Where in the stages, the author will design student worksheets based on ethnomathematics, then test its validity after it is used in the learning process and during the learning process, student activities will be observed to see the level of student activity during learning using LKS developed by the author. After the learning process is complete, students will be tested using a learning outcomes test. From the results of the study, it was found that the use of ethnomathematics-based LKS in grade VII students of SMPN I was effective, this can be seen from the learning outcomes and activities of the students studied meeting the effective criteria.

Abstract

The objective of this research were to find out 1). the level of grammatical and mechanic accuracy in the opinion essays by the third semester students. 2). the difference in the level of grammatical and mechanics accuracy between peer-correction and self-correction technique in writing opinion essay by the third semester students of UKI Toraja. This research is a quantitative research. The population of this research is the third semester students of English study program which consists of 3 classes. To select the sample, the writer uses a cluster sampling technique by selecting two classes. The instrument used to collect data is a written test. The results of the research shows that there were differences in the results of the implementation between the peer-correction technique and the peer-correction technique. The average score of students from the implementation of peer-correction is 76.5 and it is classified into the good category while the score of the self-correction implementation is 57.7 and it is classified into poor category. Therefore, it can be concluded that the peer-corection implementation is better than the selft-corection implementation.

Abstract

Metode mengajar yang digunakan dalam pembelajaran Matematika di SD sebaiknya dikemas dalam bentuk “belajar sambil bermain”. Pengajar sebaiknya bisa memilih dengan cermat metode mengajar yang mendorong siswa untuk aktif dalam kegiatan belajar mengajar. Hal ini bertujuan agar siswa lebih menguasai konsep dan nilai-nilai lebih mendalam dari bahan ajar Pendidikan Matematika. Salah satu metode yang bisa diterapkan yaitu Jarimatika. Masalah yang dihadapi oleh murid di SDN No. 213 Inpres Lemo dalam belajar matematika adalah mereka sulit memahami materi, menunjukkan sikap acuh tak acuh dalam pembelajaran, selain itu matematika dianggap sebagai pelajaran yang susah untuk dipahami sehingga berdampak pada motivasi yang rendah. Kegiatan abdimas ini dilaksanakan di SDN No.213 Inpres Lemo, Kab.Tana Toraja. Dengan metode pengajaran teknik jarimatika, ini dianggap paling ampuh dalam menanamkan konsep dasar matematika, karena di samping tidak terlalu memberatkan kinerja otak dalam berpikir, Teknik ini juga membangkitkan motivasi karena didalamnya anak belajar sambil bermain. Dari hasil abdimas ini, didapatkan kesimpulan bahwa permasalahan yang dihadapi mitra dapat tertangani, hal ini terbukti dari hasil belajar dan motivasi belajar yang mengalami peningkatan yang sangat signifikan. Penekanannya adalah guru perlu mendesain pembelajaran dalam bentuk yang menarik karena dengan cara itu terbukti mampu membuat hasil dan motivasi belajar anak lebih baik.
