Abstract

Salah satu sub bab pada mata kuliah gizi dan kesehatan pada Jurusan Biologi UNNES adalah antioksidan. Pembelajaran antioksidan dalam pelaksanaanya belum disertai bahan ajar berdasarkan kehidupan nyata. Bahan ajar berbasis riset merupakan bahan ajar yang disusun berdasarkan hasil penelitian dalam kehidupan nyata. Penelitian ini bertujuan untuk mengkaji pola konsumsi masyarakat pesisir Indramayu, mengetahui sumber makanan antioksidan yang dikonsumsi, menganalisis kevalidan bahan ajar berbasis pola konsumsi, dan mengetahui kefektifan bahan ajar yang dikembangkan berdasarkan hasil belajar mahasiswa. Hasil penelitian menunjukkan bahwa pola konsumsi makanan pokok yaitu beras, pola konsumsi hewani cukup tinggi teruatama hasil laut dan tambak ikan, pola konsumsi buah-buahan masih rendah dengan frekuensi 0 dalam sehari sebanyak 75%, dan pola konsumsi sayuran cukup baik dengan frekuensi >3 kali dalam sehari sebanyak 43%; sumber makanan mengandung antioksidan yang dikonsumsi masyarakat pesisir Indramayu yaitu buah dukuh sebanyak 240 buah dalam sehari dengan kandungan antioksidan berupa vitamin A sebesar 13,0 IU/100g (USDA), dan terung sebanyak 20 buah dalam sehari dengan kandungan antioksidan berupa vitamin C sebesar 2,2 mg/100g, vitamin B sebesar 0,41 mgl100g, dan vitamin A sebesar 23 IU/100g; bahan ajar yang dikembangkan dinyatakan valid dengan rerata skor 3,9; dan bahan ajar dikatakan efektif berdasarkan perhitungan N-gain dengan kategori sedang.   One of sub chapters on nutrition and health courses in Biology Department of UNNES is antioxidant. However, in learning process, the material about antioxidant is not accompanied by a real-life teaching materials. Research-based instructional material is teaching materials that created based on the results of research in real life. This research was aimed to examine the consumption patterns of Indramayu coastal society, know the antioxidant food sources that are consumed, analyze the validity of teaching materials based on consumption patterns, and determine the effectiveness of developed teaching materials based on student results. The results showed that consumption pattern of staple foods such as rice, consumption pattern of animal is high enough especially seafood and fish from ponds, the consumption pattern of fruits is low with a frequency of 0 in the day as much as 75%, and the consumptionpattern of vegetables is quite good with a frequency of > 3 times in a day as much as 43%; source foods containing antioxidants consumed by Indramayu coastal society is dukuh fruit as much as 240 pieces in a day with the content of antioxidants such as vitamin A at 13.0 IU / 100g (USDA), and eggplant as many as 20 pieces in a day with the content of antioxidants such as vitamin C by 2, 2 mg / 100g, 0,41 mgl100g vitamin B, and vitamin A by 23 IU / 100g; then, developed teaching material is stated valid with a mean score of 3.9; and effective as a teaching material based on the calculation of the N-gain in the medium category.

Abstract

A total of 25% of 38 teacher in SMP Negeri 10 Semarang conducted a portfolio assessment. Observation results obtained attitudes and low process skills. Learning achievement of new motion system material is 44% complete Minimum Mastery Criteria (KKM) 75%. Alternative learning models used to overcome these problems are project-based learning (PjBL) with portfolio assessment. The purpose of this study was to analyze the completeness of attitude, science process skills, improvement of learning achievement, and differences in learning achievement of students in the material of the motion system with PjBL models using portfolio assessment. The design of this study was Pretest and posttest control group design. Completeness of attitudes, skills, learning achievements were analyzed by the proportion of one party. Improved learning achievement with the N gain test. Anava 1 way is used to see the difference between the two learning achievement scores of Experiment Groups 1, 2 and Control. Independent t-test is used to see Learning Achievement Levels for Experiments Groups 1 and 2. The results showed that: (1) the attitudes of the experimental class students reached completeness asan 63 (72.79) with a percentage of 81.26%; (2) the science process skills of the experimental class students reached completeness ≥ 63 (70.83) with a percentage of 90.63%; (3) Learning achievement results are stated to be completed individually with a value of ≥ 71 (mean 79.28) and classical with ≥ 80% (84.38%); Learning achievement in the motion system material with PjBL model using portfolio assessment increases with N-gain of 0.65 (moderate); (4) F count > F table (6,699> 3,094), so Ho is rejected, so there is significant differences between experimental class 1, experimental class 2, and control; (5) the value of t count < t table (1.165 <1.998) then Ho is accepted, which means that there is no significant difference between the experimental group 1 and experiment 2.
