Educators play an important role in developing learning tools that are interesting and by the needs of students. This aims to develop a QR Code-Practical Guide based on Guided Inquiry for Class XII MIPA at the High School Level on growth and development in plants and photosynthesis and to determine the validity, practicality, and effectiveness. This type of research is Research and Development with the ADDIE model which consists of 5 stages, namely Analyze, design, development, Implementation, and evaluation. The research location is at SMAN 2 Majene, East Banggae District, Majene Regency, West Sulawesi Province. The research subjects were class XI MIPA 5 which consisted of 31 students. The results of the validation of the QR Code Practical Guide based on Guided Inquiry using the assessment sheet of media experts and material experts who were assessed by 2 expert validators obtained a result of 3.8 which is included in the valid category. The results of the practicality of the QR Code Practical Guide based on Guided Inquiry using teacher response questionnaires and student response questionnaires. The results of the questionnaire analysis show that the value of the teacher's response is 92.6%, getting the very practical category and the value of the student's response is 86.6% getting the very practical category. The results of the QR Code Practical Guide based on Guided Inquiry using test questions, the learning outcomes obtained are 80.7% in the effective category. Thus the QR Code Practical Guide based on Guided Inquiry is declared valid, practical, and effective to be used as teaching materials.

Cilallang Fisherman's Village is a densely populated settlement because it is included in the Majene city area so that residents are constrained by the limited availability of land for farming. This Fisherman's Village is also a stunting locus that requires special attention in fulfilling nutritional intake for the children of local fishermen. Another condition that also occurs in this village was the high rate of waste disposal, both in the form of organic waste and inorganic waste. Therefore, this mentoring program aimed to provide education on how to grow healthy vegetables using the hydroponic technique, which did not require a large area of land and the planting media could use plastic waste from residents so that it was eco-friendly. The activity was carried out in several stages, namely: the preparation stage, the training stage, and the monitoring and evaluation stage. The results of the analysis of activity questionnaire data consisting of 31 respondents were 73.95% strongly agree (SS) and 23.56% agree (S) obtained the benefits of eco-friendly hydroponic vegetable cultivation education.

Sistem usahatani integrasi dapat memberikan manfaat tambahan bagi petani kecil, menengah, maupun besar yaitu berupa daur ulang limbah tidak terpakai sebagai sumberdaya yang dapat menyediakan sumber penting bagi produksi seperti pupuk, pakan, dan bahan bakar yang membuat aktivitas bertani berjalan ekonomis dan berkelanjutan secara ekologis. Tujuan penelitian ini yaitu (1) mengetahui pola kakao integrasi ternak, (2) menganalisis kelayakan usahatani kakao integrasi ternak, (3) menganalisis pendapatan usahatani kakao integrasi ternak dan usahatani kakao yang tidak terintegrasi di Desa Tapango Barat, Kecamatan Tapango, Kabupaten Polewali Mandar. Pengambilan sampel dalam penelitian ini dilakukan dengan cara purposive sampling, dengan observasi terlebih dahulu di daerah penelitian. Penelitian ini bertujuan untuk mengetahui pola penerapan usahatani kakao integrasi ternak dan mengetahui kelayakan penerapan usahatani kakao integrasi ternak serta mengetahui perbandingan pendapatan usahatani kakao integrasi ternak dengan usahatani yang tidak menerapkan integrasi (usaha kakao). Metode analisis usahatani kakao integrasi ternak data yang digunakan dalam penelitian ini adalah metode analisis pendapatan petani, metode uji-t dan metode R/C Ratio. Dari hasil penelitian dapat disimpulkan bahwa (1) Pola penerapan usahatani kakao integrasi ternak yaitu dilakukan secara tradisional yang dicirikan pemberian pakan dan kandang ternak yang sederhana, (2) Berdasarkan nilai R/C Ratio sebesar 1,8 maka usahatani kakao integrasi ternak layak untuk diusahakan, (3) Pendapatan petani kakao integrasi ternak lebih besar dibandingkan dengan petani yang tidak menerapkan integrasi (petani kakao). Adapun perbandingan pendapatan petani dengan menggunakan uji -t yaitu ada perbedaan pendapatan tapi tidak signifikan.
