Abstract

Serangan Hama burung pipit dan monyet dilahan sawah mengakibatkan kerugian hasil panen yang signifikan. Selama ini, petani masih menggunakan metode tradisional seperti orang-orangan sawah dan bunyi-bunyian manual untuk mengusir hama, namun cara tersebut kurang efektif dalam jangka panjang. Serangan burung pipit mengakibatkan penurunan hasil panen hingga 50% sehingga tim pengabdian mengimplementasikan alat pengusir hama berbasis Internet of Things (IoT) yang dapat dipantau melalui perangkat Android yang telah dibuat. Alat ini menggunakan sensor ultrasonik untuk mendeteksi pergerakan hama yang dapat menjangkau area sawah yang sulit diawasi secara langsung. Pelaksanaan kegiatan meliputi implementasi alat, pelatihan penggunaan alat bagi kelompok tani, serta pendampingan lapangan selama masa uji coba. Hasil kegiatan menunjukkan bahwa penerapan alat IoT ini mampu mengurangi serangan hama hingga 70% dibandingkan metode manual sebelumnya. Selain itu, pemahaman petani terhadap teknologi tepat guna meningkat, terlihat dari kemampuan mereka dalam mengoperasikan serta merawat alat secara mandiri.

Abstract

Coffee is one of the plantation commodities which has an important role in Indonesia's economic activities. The development of coffee processing, both on a small scale and on an industrial scale, will produce by-products called coffee waste. Coffee grounds waste is waste produced from the coffee processing process which reaches almost 45% of total production. The aim of this research was to determine the secondary metabolite and total phenol content of robusta coffee grounds in Bener Meriah Regency. The method used in this research is the experimental method. The resulting coffee grounds will be extracted using a solvent, and the resulting extract will be tested for secondary metabolites and total phenols. This test will be carried out in the chemistry laboratories of FKIP Unimal and FKIP USK. The results of testing the secondary metabolite content and total phenol content in Robusta coffee grounds were Alkaloids (Dragendrof, Mayer and Wagner), Saponins, Flavonoids, Polyphenols and Steroids, and the total phenol content was 87.38 (mg GAE/g extract).

Abstract

The low level of students’ problem-solving skills and awareness of energy-saving behavior highlights the urgency of developing contextual teaching materials aligned with the Merdeka Curriculum. This study aimed to develop and evaluate the effectiveness of a Creative Problem Solving (CPS)–based e-module to improve students’ problem-solving skills while fostering energy-saving character. The research employed a quasi-experimental design with a pretest–posttest control group. The sample comprised two eleventh-grade science classes purposively selected from a senior high school in Aceh Utara Regency, Indonesia. Effectiveness analysis was conducted by comparing learning outcomes between the experimental and control groups. The results indicate that the CPS-based e-module effectively improved students’ problem-solving skills, with an average N-Gain score of 71.73, classified as high. In addition, the e-module contributed positively to the development of energy-saving character, as reflected in improvements in most indicators (frugality, accuracy, tolerance, and creativity) toward habitual behavior. These findings imply that CPS-based e-modules have the potential to serve as integrated learning innovations that enhance instructional quality while fostering energy-saving character at the secondary education level.
