Abstract

This research aims to develop a valid, practical, and effective Aksi learning model. The research method used is development research with adaptation of Thiagarajan development steps. Based on the results of the needs analysis on the questionnaire given to 15 science teachers in several regions in East Java, educators stated that the students' higher-order thinking skills were not optimal. Higher-order thinking skills show that students have C4, C5, and C6 knowledge abilities. Based on these data it is necessary to develop a learning model that fits the needs, the Aksi learning model. This research aims to develop a valid, practical, and effective Aksi learning model. The research method used is development research with an adaptation of the development steps developed by Thiagarajan. The 4D development model is carried out with 4 research stages namely Define, Design, Develop, and Disseminate. Aksi learning model development research produces data in the form of valid, practical, and effective values. The Aksi learning model has a validity score of 88.10% in the very valid category. The practicality value of the observation of the implementation is 89.24% in the very practical category, the teacher response test was 89,38% in the very practical category, and the student response test was 84.12% in the very practical category. The value of the model's effectiveness is to get an N-gain score for high-level thinking skills, which is 0.7 in the high category.

Abstract

The Piperaceae family is one of the aromatic plants that have a distinctive odor and is known to have tremendous benefits in human life.  Piperaceae is used as raw material for medicines, spices, antibacterial, antiviral, and insecticides. Research on the composition of volatile chemical compounds in Piperaceae members is still limited. This study aims to extract volatile chemical compounds in the Piperaceae family and classify Piperaceae members based on their volatile compounds. The type of research is laboratory research. The research samples were leaves of ten species of Piperaceae members, namely Piper cubeba, P. nigrum, P. betle, P. ornatum, P. retrofractum, P. sarmentosum, Peperomia pellucida, Peperomia scandens, Peperomia caperata, and Peperomia maculosa. The research instrument was an observation sheet of SPME-GCMS analysis results. Data in the form of metabo-analysis was obtained from laboratory analysis using SPME-GCMS by producing a comprehensive volatile compound profile of the Piperaceae family and revealing differences between species. The results of SPME-GCMS analysis on the Piperaceae family obtained 197 identified volatile chemical compounds. The largest group of chemical compounds in 10 species of the family consists of sesquiterpene (16.2%), monoterpene (11.7%), sesquiterpenoid (7.1%), alcohol (6.1%), aldehyde (4.6%), terpene (4.1%), terpenoid (4.1%), alkene (3%), fatty acid (2.5%), ketone (2.5%), phenol (2.5%), alkane (2%) and other groups less than 2%.  Characteristics of typical compounds in the genus Peperomia amounted to 10, namely Alpha-pinene, (-)-; Camphene; 2-beta-pinene; l-Limonene; Nonanal; (-)-.beta.-Elemene; alpha.-Copaene; Germacrene D; cis-caryophyllene; Bicycloelemene. In the genus Piper, the variation in the character of volatile chemical compounds is very large, typical characteristics possessed by 6 Piper species are alpha-pinene, (-)-; alpha.-Copaene; alpha.-Humulene; (-)-beta.-Elemene; and trans-Caryophyllene. The study concluded that 197 volatile compounds from 10 Piperaceae species had been identified. The results of this study can be recommended that the Piperaceae family can be optimized for public health.

Abstract

Piper sarmentosum Roxb or known as mana Karuk is an aromatic plant that has extraordinary potential, namely as a mucus expectorant, its roots are efficacious as a ureter and overcome gallstones. This plant is also used as an asthma drug, a cure for skin diseases such as tinea versicolor, stomach pain, malaria medicine, relieve bone pain and dental pain. The components of aromatic chemical compounds in the leaves and fruits from Meru Betiri National Park (MBNP) have not been identified. This study aimed to identify and analyze the aromatic components of P. sarmentosum leaves and fruits from MBNP using SPME-GCMS. The research method is laboratory research. The research samples and research materials were the leaves and fruit of the P. sarmentosum plant taken in MBNP. The SPME-GCMS tool is used in research to identify and analyze aromatic compounds. The research instrument used was an identification and analysis sheet of aromatic compounds from the P. sarmentosum plant. The data analysis technique uses the SPME-GCMS test. The results of the study showed that there were 46 volatile compounds found in the leaves, while in the fruit there were 29 volatile compounds. The main aromatic compound groups in the leaves and fruits of P. sarmentosum are terpenes, namely monoterpene. The other components consist of organic benzene compounds. P. sarmentosum Roxb. has 46 aromatic compounds in the leaves and 29 other aromatic compounds found in the fruit. Furthermore, research results must be tested in more depth regarding biological activity and mechanism of action through the best methods so that they can be recommended as new drug innovations in society.

Abstract

Abstract: This study aims to determine the validity and effectiveness of the Culturally Responsive Teaching-based science module in improving the ecoliteracy of junior high school students in Jember Regency. The subjects in this study were students of class VIII F SMPN 1 Ajung totaling 31 students, with 17 male students and 14 female students. The research model used in this study is the 4-D (Four D) development model which consists of four stages including define, design, develop, and disseminate. The instruments in this study were interview guidelines, validation sheets, and pre-test and post-test sheets for students. The validity data analysis was obtained through a validation questionnaire validated by three expert validators, and the effectiveness data analysis was obtained through the results of the pre-test and post-test given to students at the time before the application of the Culturally Responsive Teaching-based science module and at the time after the application of the Culturally Responsive Teaching-based science module. The validity results of this study obtained an average assessment score from the three expert validators of 94% with very valid criteria so that culturally responsive teaching-based modules can be applied to science learning. The results of the effectiveness of culturally responsive teaching-based modules produce an average N-Gain value at SMPN 1 Ajung of 0.85 with high-value criteria so that students can increase student ecoliteracy. Based on the research results, it is concluded that developing culturally responsive teaching-based modules is valid and effective in improving students' ecoliteracy.         Keywords: culturally responsive teaching, ecoliteracy, learning module. DOI: http://dx.doi.org/10.23960/jpmipa/v25i1.pp329-340
