Abstract

Pengabdian yang telah dilakukan merupakan kegiatan dalam rangka peningkatan usahadan pengembangan usaha mitra. Salah satu proses pengolahan batok kelapa menjadiarang adalah proses pemisahan debu arang dari lempengan arang, yaitu prosespengayakan. Proses ini merupakan salah satu permasalahan yang dihadapi oleh MitraUsaha Arang Batok Kelapa karena masih menggunakan cara manual. Oleh karena itu,diperlukan penerapan IPTEK yang lebih mumpuni untuk mengurangi beban tenagamanusia sekaligus meningkatkan kesehatan pekerja. Tujuan dari kegiatan ini adalahuntuk mengurangi beban pekerja, meningkatkan kuantitas dan kualitas produk arang,meningkatkan nilai ekonomis produk, serta memenuhi kebutuhan pupuk organik yangmurah bagi petani. Kegiatan PKM ini diawali dengan survei awal ke lokasi mitra untukmenentukan solusi atas permasalahan yang ada, dilanjutkan dengan pembuatan mesinpengayak, pemberian pelatihan cara operasional alat, perawatan, dan pembimbingan. Hasildari PKM ini adalah tercapainya target luaran PKM, di mana mitra telah diberikan bantuanberupa mesin pengayak yang beroperasi secara mekanis untuk menggantikan pekerjaanmengayak arang secara manual. Mitra dan pekerja telah mendapatkan pelatihan danbimbingan terkait pengoperasian serta perawatan mesin, sehingga mampu memproduksiarang tempurung kelapa secara maksimal dan efisien.

Abstract

Silat Perisai is one of the cultural heritages of the Pucuk Adat, Kampar Regency, Riau Province, which has existed since before the independence of the Republic of Indonesia and since 2017 has been included in the Intangible Cultural Heritage. This study aims to evaluate the results of ethnomathematical exploration carried out by students of Mathematics Education at Pahlawan Tuanku Tambusai University in the Silat Perisai movement. This research is a descriptive study with a case study on ethnomathematical exploration in Silat Perisai. Researchers observed the exploration process carried out by students, and evaluated reports on exploration results. Student errors are viewed from two aspects, namely aspects of mathematical concept errors and aspects of ethnomathematical exploration procedures errors. Before carrying out the exploration, the student group first validated the research instruments used, such as observation sheets and interviews. The results showed that the overall level of error in disclosing ethnomathematical concepts of flat shapes reached 50%, which means that students' errors in expressing concepts are still relatively moderate. The procedural error rate in ethnomathematical exploration reaches 40%.

Abstract

This study is based on the low ability of students in mathematical communication in class X of SMA Negeri 1 Kuok, which can be seen from their learning outcomes. The purpose of this study was to evaluate whether there was an impact of the implementation of the problem-based cooperative learning model on students' mathematical communication skills in class X of SMA Negeri 1 Kuok. This type of research is a quasi-experimental study with a sampling technique using simple random sampling. The population studied were students of class X of SMA Negeri 1 Kuok for the 2024/2025 Academic Year which were divided into two classes. The selected sample was class X.1 as the control group and class X.2 as the experimental group. The instruments used in this study included observation sheets and test questions to measure mathematical communication skills. The data analysis method applied was the Independent Sample T-Test with the support of SPSS 25 software. The average Pre-test score of students' mathematical communication skills in the experimental class was 40.00, while the control class reached 47.39. The average Post-test score of students' mathematical communication skills in the experimental class increased to 72.17, while the average control class was 61.96. Thus, it can be concluded that there is an influence of the Problem Based Learning learning model on students' mathematical communication skills in class X of SMA Negeri 1 Kuok. This can be proven through the Independent Sample T-Test which shows a sig (2-tailed) value of 0.000 which is smaller than 0.05, so H0 is rejected and Ha is accepted.

Abstract

Candlenut seeds are one of the plants that grow in Indonesia. Candlenut leaves and seeds have many benefits that are useful for human life. Candlenut oil can be used as a raw material for making varnish, paint, soap, fabric oil, resin, synthetic leather, lubricants, compost, and cleaning or polishing mixtures. Candlenut fruit has a shape ranging from oval to round, green to brownish green, with a length of ± 5–6 cm and a width of ± 5-7 cm. One candlenut contains one to three candlenut seeds. To get the candlenut seeds, they must be removed from their hard and thick shell by breaking them.So far, getting candlenut seeds has been done by breaking them manually by hitting them one by one. This is certainly not effective and takes a long time. Based on this, a tool was designed and made for breaking candlenut shells using a 2 HP motor drive. This candlenut shell breaker tool consists of a throwing part that rotates vertically, which, due to the centripental effect, throws the candlenut kernels against the wall of the breaker. The broken candlenut kernels and shells fall down into the filter section to separate the kernels and shells, then the candlenut kernels go inside. holding containers. To get the ideal launcher rotation, several speed variations were tested, namely: 1. 250 rpm, 2. 350 rpm, and 3. 500 rpm. Of the three variations of rotation, the best rotation was obtained with the shell breaking and the seeds releasing well without breaking, namely at 350 rpm.

Abstract

This study aims to analyze the effect of the JUCAMA learning model assisted by the Math Solver application on students' mathematical critical thinking skills. The background of this research is the importance of developing critical thinking skills in mathematics learning, as well as the need to utilize learning models and technology that can support this process. This study uses a quantitative approach with a quasi-experimental design and involves seventh-grade students at MTs in Sawah Village as research subjects. Sample selection was done using purposive sampling with two classes: the experimental class using the JUCAMA model and the control class using expository learning. The research instruments include a critical thinking skills test covering indicators of interpretation, analysis, evaluation, and inference. The research results indicate that there is a significant influence of implementing the JUCAMA learning model assisted by the Math Solver application on improving students' critical thinking skills. Students who participated in learning using the JUCAMA model showed higher achievement in the indicators of interpretation, analysis, evaluation, and inference compared to students who underwent expository learning. These findings suggest that using the JUCAMA model with the support of digital technology can be an effective strategy in developing students' mathematical critical thinking skills.
