Abstract

The type of research applied in this research is Research and Development. The development model used is Dick and Carrey. The purpose of this research and development is to design an Atlas and apply it to train the students' scientific reasoning abilities. Atlas is a teaching materials developed and applied to high school / vocational / MA level students. The sample chosen for the implementation of the Atlas of teaching materials was grade X of VOCATIONAL Health Yannas Husada Bangkalan students. The application of plants as natural indicators of acid-base tests is the material presented in the developed Atlas. Plants selected as indicators are tested first to be presented in the Atlas. Atlas is a teaching material that can convey information related to the use of natural indicators of the acid-base test to train the students' scientific reasoning skills. The four indicators of scientific reasoning that are trained are Theoretical Reasoning, Proportional Reasoning, Probabilistic Reasoning, and Correlational Reasoning. The data shows the students' scientific reasoning ability on the post-test results, as many as 20% of students are on the high criteria, 60% are moderate criteria, and 20% are still on the low criteria from the post-test results. The post-test result data is quite increased when compared to the pretet results, which 100% of students are in the low criteria.

Abstract

This research aims to produce IPA learning devices with the approach of Socio-Scientific Issues (SSI) on climate change materials to improve the science literacy of Junior high school students. The learning devices developed are syllabus, learning Implementation Plan, Student teaching materials, Student Worksheets, and Science literacy test. This type of research is development research with the model Dick and Carey. Test learning devices in the classroom using one group pre-Test post-Test design. The research instruments in this study are validation sheets, learning implementation observation sheets, activity observation sheets, test sheets, and student response polls. Data collection using validation methods, observations, tests, and polls. Data analysis techniques use quantitative descriptions. The results of the study show that learning devices are declared worthy of validity, practicality, and effectiveness. The validity aspect indicates that the learning device is very valid and reliable. The practicality aspect of the practice of learning has an average 3.66 with excellent criteria and an student activity is very active. The average achievement of science literacy from 32 students in class VII A when pre-test was at level 2 experienced an increase when post-test was at level 4. Based on N-Gain test the value of 0.50 is on medium criteria. Students ' response to the application of a Socio-Scientific Issues (SSI) approach to climate change material is very good.  Learners give a positive response of 87.60%.

Abstract

Perairan Indonesia memiliki potensi sumber daya laut yang tinggi, sehubungan dengan hal tersebut, Indonesia juga merupakan salah satu negara yang memiliki kawasan hutan mangrove (hutan bakau) terluas di dunia. Salah satu potensi dari tanaman mangrove yang mulai banyak dikembangkan yakni buah mangrove sebagai sumber pangan, seperti sari buah mangrove pedada. Tujuan dari penelitian ini adalah untuk mensintesis, karakterisasi, dan uji aktivitas antifungi nanosilver dalam sari buah mangrove. Pada penelitian ini sari buah mangrove dibagi menjadi tujuh perlakuan yakni K- tanpa penambahan agen antifungi (sebagai kontrol negatif), K+ dengan penambahan 0,1% natrium benzoat (sebagai kontrol positif), F1 hingga F5 dengan variasi kadar penambahan nanosilver sebesar 4%, 8%, 12%, 16%, dan 20%. Uji aktivitas antifungi dilakukan menggunakan metode Direct Microscopic Count (DMC) dengan teknik penghitungan langsung. Berdasarkan hasil penelitian ditunjukkan bahwa penambahan nanosilver memberikan pengaruh yang berbeda nyata di tiap konsentrasinya terhadap aktivitas antifungi dalam sari buah mangrove pedada. Perlakuan pada sampel F2 (dengan kadar penambahan nanosilver 12%) merupakan formulasi optimum dari semua perlakuan. Pada uji organoleptik, penambahan nanosilver hanya memberikan pengaruh nyata pada warna namun tidak memberikan pengaruh yang berbeda nyata pada mutu fisik berupa aroma, tekstur, dan juga pH.

Abstract

Gresik Regency is very rich in its typical food involving UMKM. They were still use many synthetic additives such as dyes, flavors, and flavorings with the aim of beautifying the appearance and strengthening the taste. The continuous use of synthetic additives can interfere with health and also many have not met halal criteria. They do not know or apathetic to the dangers posed by the use of additives, so it is necessary to carry out socialization related to healthy and halal ingredients. The methods used are counseling and practice of identifying ingredients based on nutritional composition and critical ingredients and conducting evaluations through response questionnaires. The results showed that 36.4% of participants did not know how to identify halal products; 36.5 – 45.5% still use synthetic additives and 90.9% their knew the effects of using synthetic additives. The practice showed that UMKM do not understand critical materials so that follow-up needs on understanding critical materials.
