Tujuan pengabdian ini adalah menyediakan wahana bagi siswa-siswi SMP dan sederajat, untuk mengembangkan minat dan bakat dibidang IPA sehingga dapat meningkatkan kemampuan intelektual, emosional, dan spiritual 2) Meningkatkan komunikasi antara program studi dengan para stakeholder atau sekolah dan outcomes atau lulusan dan sekaligus sebagai ajang promosi program studi kepada masyarakat 3) meningkatkan kemampuan guru untuk membimbing siswanya untuk mengikuti olimpiade IPA. Metode yang digunakan dalam kegiatan ini adalah pendampingan kegiatan olimpiade IPA tingkat SMP se-Kabupaten Ngada dan Nagekeo. Terdapat 57 siswa yang berasal dari 12 sekolah. SMP yang mendaftar yaitu

Research paper thumbnail of Pengaruh Bentuk Daun Lontar Terhadap Intensitas Bunyi Alat Musik Sasando

Sasando tergolong alat musik chordophone karena dimainkan dengan cara dipetik. Salah satu penyusun konstruksi sasando adalah daun lontar (siwalan). Penelitian ini bertujuan untuk mengetahui pengaruh perubahan bentuk daun lontar (siwalan) secara horizontal terhadap intensitas bunyi yang dihasilkan. Lebar horizontal daun lontar divariasi sebesar 30 cm, 35 cm, 40 cm, 45 cm, 50 cm, dan 55 cm. Intensitas bunyi yang dihasilkan diukur dengan menggunakan Sound Level Meter (SLM). Berdasarkan hasil penelitian yang diperoleh menunjukan bahwa ada perubahan nilai intensitas bunyi jika diameter horizontal daun lontar dirubah-rubah ukurannya. Nilai intensitas bunyi rata-rata Sasando berubah bervariasi dari 9,68 x 10-7 W/m2 sampai 2,85 x 10-5 W/m2. Nilai intensitas bunyi yang paling tinggi berada pada diameter 40 cm sedangkan nilai intensitas bunyi yang paling rendah berada pada diameter 50 cm.

Research paper thumbnail of Analysis of the Mechanical Properties Brake Canvas with Basic Ingredients of the Durian Fruit Skin and Teak Leaves

This study aims see the mechanical properties of organic brake canvas made from durian fruit skin and teak leaves. Composite making was done by smoothing durian fruit and teak leaves to become powder. The resulting powder was filtered with mesh 60 so that the particle size is the same so as to facilitate mixing. After that, simple mixing with other ingredients such as magnesium oxide and polyester resin is carried out. The printing process was carried out with a hydraulic press with a load of 4 tons for 3 hours. The brake canvas produced were tested for hardness, wear resistance, and absorbency by varying the percentage composition of the powder of durian fruit fiber and teak leaves. There are five variations in the percentage of composite material composition tested. The results obtained the percentage of the most optimum composition that has a value of hardness, wear wear resistance, a...

The purpose of this study is to determine the supporting and inhibiting factors for the implementation of the independent curriculum at SMP Negeri 4 Golewa. This research method uses a qualitative approach. In collecting data, researchers use observation, interview, and documentation techniques. Data analysis carried out includes data condensation, data presentation and drawing conclusions. The results showed that supporting factors for the implementation of the independent curriculum include adequate facilities and infrastructure and teaching staff who want to learn about the independent curriculum, while inhibiting factors for implementation include lack of references, new teacher experience, and there are still teachers who do not attend the independent curriculum webinar

Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian studi kasus. Teknik pengumpulan data yang digunakan adalah wawancara, observasi, dan studi dokumen. Berdasarkan hasil penelitian di lapangan, dapat diketahui bahwa dari hasil pembelajaran tematik kelas awal di SDN Koeloda yang telah tercapai melalui perencanaan dan penggunaan strategi pembelajaran namun belum normal, maka dapat dikatakan pembelajaran tematik efektif untuk memberikan pengalaman belajar dan efisien dalam pelaksanaan serta memberikan daya tarik bagi peserta didik untuk belajar perlu ditingkatkan oleh guru.

Collecting data by using the observation sheet at each meeting. The technique of data analysis using descriptive analysis. Results of data analysis shows that on average during the three meetings have been 77.8% of students with a scientific high category, 19.4% of students have been scientifically medium category, and 2.7% of the students is still low in the scientific attitude. Thus the application of physics learning with computer media use through the implementation of an effective model for cooperative type STAD X 3 geade students at SMAN I west Bangkinang subject matter of heat.
