Abstract

This research is experimental research. The research aims to analyze the absorbance and wavelength values on the certain color spectrum based on the age of noni leaf sample. Variation in absorption and wavelength occurs in the red spectrum ranges between 650 to 700 nm. Maximum absorption occurs in the middle of noni leaf followed by the tip of noni leaf sample but the yellow leaf sample results poor absorption. Chlorophyll a has main leaf pigment the most which occurs in the light reaction of photosynthesis. The maximum absorption which ranges between 3,5 to 4,0 A occurs in the blue spectrum ranges between 400 to 450 nm. Chlorophyll b absorbs photon energy in sun light. A wavelength ranges between 500 to 600 nm occurs in the green spectrum which has low absorption of three samples ranges 0,5 to 1,5 A. The chlorophyll reflects light of the green spectrum; therefore, it causes low absorption.

Abstract

Conventional learning models that still dominate the science learning process have a negative impact on learning psychology and student learning outcomes, for example the lecture method. In addition, the integration of local knowledge in learning almost done because the teacher thought local knowledge of science content is not relevant to modern science. This study has the prospect to develop an integrated learning tools nested models based on local wisdom phinisi boat. Products developed focuses on improving communication skills and conceptual knowledge of students. Adapting product development methods development framework Dick and Carey to modify it in 5 stages. Stages of needs analysis, product design, product development, product implementation and evaluation, and the final product. The results of product development tested in a limited class of the class VII SMPN 32 Bulukumba the 15 students who have been selected by purposive sampling. The choice of subjects represented each of 5 students with low, medium, and high abilities. Primary data were obtained from the assessment of the product by 2 experts and through the assessment questionnaire. The feasibility of the product in the category "very high". The syllabus has a validity level of 94.00%, RPP 93.75%, LKPD 96.00%, and assessment instruments 95.00%. Response practitioners and learners in the category ratings "high" and "very high" throughout the assessment indicators. In the implementation phase, learning nested models based on local wisdom boat phinisi provide more space for students to express their knowledge and digging skills

Abstract

Kedisiplinan berperan penting dalam membentuk karakter mahasiswa sains yang mandiri, bertanggung jawab, dan berintegritas. Namun, banyak mahasiswa masih menghadapi tantangan dalam menerapkan disiplin, seperti kurangnya ketepatan waktu, rendahnya kepatuhan terhadap aturan akademik, serta minimnya kesadaran akan tanggung jawab akademik dan sosial. Penelitian ini bertujuan untuk menganalisis peran kedisiplinan dalam membentuk karakter mahasiswa sains di Universitas Tompotika Luwuk. Metode yang digunakan adalah kualitatif deskriptif dengan teknik pengumpulan data melalui wawancara mendalam, observasi partisipatif, dan dokumentasi. Hasil penelitian menunjukkan bahwa tingkat kedisiplinan mahasiswa masih rendah, terutama dalam kepatuhan terhadap aturan akademik dan konsistensi dalam menyelesaikan tugas. Faktor-faktor yang memengaruhi kedisiplinan meliputi lemahnya kontrol akademik, minimnya keteladanan dari dosen, serta kurangnya motivasi internal mahasiswa. Oleh karena itu, diperlukan strategi yang lebih efektif, seperti peningkatan pengawasan, pembiasaan yang konsisten, serta pendekatan berbasis komunitas untuk membentuk karakter disiplin mahasiswa secara optimal.
