Intuition is the first way humans get knowledge. A worker in making a traditional West Java house works using his experience to be able to determine how many building materials are needed to become a house. The roof of the house is one part that is quite complicated to determine the amount of wood needed. Workers using intuition based on experience that has been experienced greatly determine the accuracy of the measure. Through this research, the researcher hopes that the method of determining the amount of wood used to make the roof (suhunan) of houses in West Java has added scientific value because it is related to existing mathematical concepts. The subjects of this study were workers who made traditional houses in West Java Regency. This study uses a qualitative method with an ethnographic approach. This study aims to describe an in-depth study of how to determine the amount of wood used to make traditional houses and its relation to mathematical concepts. The results showed that the workers who made the traditional houses started outing for the first time by calculating the number of wood chips needed to make the KAP intact to make the roof from it, they were easier to determine the amount of wood needed.

Kompetensi pedagogik merupakan kemampuan guru dalam pengelolaan pembelajaran sedangkan kompetensi profesional merupakan kemampuan guru dalam menguasai pengetahuan bidang ilmu pengetahuan yang diampunya. Pedagogical Content Knowledge seorang guru dapat berkembang dengan baik seiring dengan pengalamannya dalam mengajar. Namun kenyataannya tidak semua memberikan pengalaman yang baik bagi pengembangan Pedagogical Content Knowledge. Sehingga penting mempersiapkan calon guru matematika mempunyai Pedagogical Content Knowledge yang baik. Alternatif pengembangan. Pedagogical Content Knowledge adalah dengan mengembangkan bahan ajar berbasis Didactical Design Research, dimana bahan ajar yang di hasilkan sesuai dengan kondisi respon mahasiswa. Untuk mengatasi permasalahan tersebut, salah satu upaya yang dapat dilakukan adalah dengan melakukan pengembangan bahan ajar melalui pembelajaran yang dapat mendorong mengembangkan pedagogical content knowledge. Pembelajaran yang memfasilitasi hal tersebut adalah pembelajaran dengan bahan ajar yang dikembangkan berbasis didactical design research (DDR). Penelitian ini menggunakan metode penelitian pengembangan dengan mengadaptasi model ADDIE (Analysis, Design, Development, Implementation, dan Evaluation). Hasil penelitian menunjukkan bahan ajar yang dikembangkan memenuhi kriteria valid berdasarkan ahli kurikulum, ahli materi dan ahli media dengan kategori penilaian sangat baik. Berdasarkan penilaian guru dan siswa, bahan ajar yang dikembangkan telah memenuhi kriteria praktis dengan kualitas sangat baik. Bahan ajar juga dinilai efektif karena hasil tes kemampuan pemecahan masalah matematika menunjukkan ketuntasan siswa sebesar 89,01%.

The water pollution caused by diamond mine activities can kill aquatic life. In this work, we used phytoremediation and filtration to treat pond water polluted by the tailings of a diamond mine located in South Kalimantan, Indonesia. Einchhornia crassipes (water hyacinth) was utilized as the biomass for the phytoremediation process. Gravel (10–15 mm) and sand (0.1–1 mm) were used as filter media in the simple filtration setup, using an up-flow system (bottom to top). In the experiment, 16 L of diamond tailing water was poured into five phytoremediation reactors (each 60 L in volume), which were then tested over seven days. A pretreatment analysis of the tailings water showed that its biochemical oxygen demand (BOD) of 8.9 mg L−1 and chemical oxygen demand (COD) of 22 mg L−1 exceeded the national maximum standards of 2 mg L−1 and 10 mg L−1, respectively. The experimental results demonstrate that both phytoremediation and filtration could increase the dissolved oxygen concentration (4.7 mg.L−1) and reduce the BOD (3.2 mg.L−1), COD (6.5 mg.L−1), Fe (0.6 mg.L−1), Mn (0.16 mg.L−1), and ammonia (0.63 mg.L−1) concentrations from those measured in the raw diamond-mine-tailings water. The phytoremediation performance was better than that of filtration. The COD values were successfully reduced to the permissible limit, although the other parameters still failed to meet the government water quality regulation requirements.

Indonesian pupils need help solving problems, particularly in mathematics, due to the need for practice questions with the higher-order thinking (HOT) type. This research aims to develop a reliable and valid tool for assessing students' higher-order thinking skills in mathematics. Developing a test involves gathering requirements, creating questions, assessing answers, running trials, analyzing data, making adjustments, and finally putting everything together. The instrument trial was conducted at SMAN at Majalengka, West Java. The total number of test subjects was 32 students. Research data were collected using a description test. The test instrument consists of 10 descriptions, but only 6 had good validity based on the value of V on the V-Aiken. In addition, the test package produces reliable questions based on Cronbach's Alpha scores. The test results of the instrument showed that the HOTS of mathematics for Grade X students was good. This step provides an overview to teachers in designing valid and relevant instruments.
