Abstract

Chaff waste which has no economic value will become of high value after being converted into rice bran through the milling process. Rice bran is very much in demand because it provides many benefits. The abundant and abundant availability of husk waste and only being left and burned is of course a problem due to the lack of information on utilizing this waste. By processing rice husk waste, it can be used as animal feed for boiler chicken and free-range chicken rations for residents who have poultry such as chickens. Furthermore, bran which is a by-product of the rice milling process can also be a staple food with high nutritional value. Bran has a high nutritional content, and so far only often used as animal feed can also be consumed with various properties, such as having a high content of B vitamins namely thiamine, niacin and B6 which play an important role in energy production, cardiovascular health and preventing depression It is also considered as a source of natural fiber. In order to be able to utilize the abundant rice husk waste, an appropriate technology design is carried out in processing rice husk waste in the Wanasigra village community into various alternative results of processing this waste to support food security. The results and outputs of community service activities for the food security scheme (PBM-KP) for the Wanasigra Village community, namely residents becoming more independent, residents can maintain the food security of their families, residents and farmer groups gain knowledge through coaching and counseling in utilizing the results from the design of rice husk waste processing technology , providing assistance to target partners to be more independent in processing rice husk waste, food availability, earning additional income for their families. The method used in the service is through counseling, discussion, mentoring and introduction and design of technology to marketing through agricultural experts appointed by external parties. Sales are facilitated by the appointed chairman to distribute to other areas outside the Wanasigra village.

Abstract

Hasil studi awal menunjukkan bahwa tingkat pemahaman konsep matematika serta konsentrasi belajar siswa, khususnya dalam topik trigonometri, masih tergolong rendah. Hal ini ditunjukan dengan sebagian peserta didik mengalami kesulitan dalam mengaitkan konsep-konsep tersebut, sehingga proses pembelajaran belum berlangsung secara maksimal. Selain itu, dinamika kelas dan lingkungan belajar yang kurang kondusif juga memengaruhi kemampuan mereka dalam mempertahankan konsentrasi selama pembelajaran. Penelitian ini bertujuan untuk mengidentifikasi sejauh mana implementasi musik klasik Mozart dapat berkontribusi terhadap peningkatan konsentrasi dan pemahaman konsep matematika dalam proses pembelajaran. Menggunakan metode penelitian kuantitatif dengan desain eksperimen semu tipe one group pretest-posttest, penelitian ini melibatkan peserta didik kelas X di salah satu SMA negeri di Ciamis sebagai sampel. Instrumen penelitian yang digunakan berupa tes pemahaman konsep dan angket konsentrasi yang telah diuji validitas dan reliabilitasnya. Analisis data dilakukan dengan Paired Sample t-Test dan N-Gain. Hasil penelitian menunjukkan bahwa terdapat peningkatan signifikan dalam rentang sedang pada pemahaman konsep. Pada konsentrasi, terdapat peningkatan yang juga dalam rentang sedang. Hasil ini menunjukkan bahwa implementasi musik klasik Mozart terbukti mendukung peningkatan pemahaman konsep matematika dan konsentrasi siswa.
