Abstract

Nowdays, the necesity of the water go up on every sectors, so that it caused the water go down because of the management is not good enough. The purpose of this study is to know the kinds of the vegetation that found in the haze, that can be benefit to suport the water availibility and conservation, to know the potency of the vegetacy as the water availibility and conservation an also to know the society role to support it. This study is started from December 2020 until March 2021 placed in haze Banfanu village, North Central Timor regency. This study is used the qualitative and quantitave method. To collect the data and analysing the writer used an interview, observation and documentation. The determination estimasy data analysing is used point center quarter method (PCQM) to count point index value (PIV), the variety index shanon winner and averrage index. This study is made on twelve simpling with the vegetation data that is pick out from the tree, pilar and seedling. The result of this study is indicated that there are 28 species in the haze at the Banfanu village that consist of 16 families from 404 individu is devided in seedling, pilar and tree. The vegetation that could be benefit the water availibility and concervation is Switenia mahagoni, Casuarina junghuniana, Syzygum aqueum, Bambusa vulgaris, Ficus benjamina, Pandanus dubius Spreng, Paraserianthes falcataria (L) Nielsen, Anacardium occidentae L, Psidium Guajava L, Timonius sericeus (Deft) K. Schum, Syzygium cimunu L. The vegetation that indicate to keep up the water avalibility concervation is Bambusa vulgaris, the vicus kind is switenia mahogani, and iti is supported by the data analysis is higher index point value to tree strata is tectona grandis with IPV 74.50% and the lower IPV is Musa paradisiaca with IPV 1.80%. The higher point value for the pilar is Gliricidia sepium with IPV 92.13% and the lower is Vachellia leucophloea with IPV 2.99%, the high IPV for seedling is Tectona grandis with IPV 46.80% and the lower is switenia mahogani L and Sesbiana grandiflora with IPV 0.90%. The variety index value Shanon Winner and the averrage index categorize is lower. The vegetacy kind in the haze of Banfanu village categorize lower variety vegetacy, bad productivities, the condition is not rateable and lower pressure, but the ratebale index happend because of the domination on the kind certain species and in generally the kind of plant that growth up is limited.

Abstract

Salah satu tumbuhan yang memiliki senyawa antioksidan ialah rumput laut hijau atau Ulva Lactuca banyak ditemukan di Desa Tiberias, Kecamatan Poigar, Kabupaten Bolaang Mongondow, namun belum di manfaatkan untuk dikonsumsi oleh masyarakat sekitar. Tujuan dalam penelitian ini adalah menguji bahan aktif dan aktivitas antioksidan dengan menggunakan metode DPPH. Penelitian ini merupakan penelitian kuantitatif yang meliputi 3 tahap kegiatan, yaitu tahapan pertama untuk memproses penyiapan serbuk dan mengekstraks, tahap kedua yakni untuk menguji fitokimia dan uji aktivitas antioksidan, serta tahapan ketiga yakni untuk menganalisis data. Rancangan percobaan ini adalah rancangan acak lengkap (RAL) dan analisis data hasil percobaan untuk uji aktivitas antioksidan menggunakan uji One-Way ANOVA dengan program IBM SPSS statistics pada α = 0.05. Hasil uji fitokimia diperoleh ekstrak etanol 70% Ulva Lactuca menunjukkan adanya kandungan alkanoid, flavonoid, triterpenoid dan steroid. Hasil inhibisi pada etanol 70% Ulva Lactuca pada konsentrasi 25, 50, 75, dan 100 ppm secara berturut-turut menghasilkan rerata inhibisi sebesar 23.81%, 48.15%, 74.33% dan 85.05% dan rerata nilai IC50 sebesar 46.68 ppm. Sedangkan alfatokoferol yang digunakan sebagai senyawa pembanding memiliki nilai IC50 sebesar 4.44 ppm. Pada uji One-Way ANOVA diperoleh nilai sig. = 0.001 (H0 ditolak jika sig. < 0.05), sehingga H0 ditolak, dan Ha diterima. Sehingga rata-rata inhibisi dari ketiga perlakuan tersebut tidak identik (berbeda secara signifikan) atau bisa dikatakan terdapat hubungan antara konsentrasi ekstraksi dan inhibisi. Konsentrasi ekstraksi memberikan pengaruh terhadap besarnya penghambatan terhadap DPPH. Dengan demikian, ekstrak etanol 70% Ulva Lactuca memiliki aktivitas sebagai antioksidan yang efektif.

Abstract

Critical thinking is an ability that must be possessed by students because critical thinking is a basic skill needed in 21st century learning. In natural sciences, the problems that are often raised are environmental problems which are related to living things. By raising general problems that occur in the environment and living things, this can be used as an aspect of discussion in biology learning, such as in heredity material which studies how the inheritance of traits is passed down from parents to offspring and evidence of inheritance, as well as studying the determinants of genetic disorders. in living things. Students' critical thinking ability is assessed based on indicators of critical thinking skills consisting of interpretation, analysis, inference, evaluation, explanation, and self-regulation.The purpose of this study is to analyze the critical thinking skill of 9th grade junior high school students at SMPN 5 Kudus in solving problems question related to heredity based on measurement that is described from indicators of critical thinking ability. Of the 26 students, the average percentage of critical thinking skills in students from the six critical thinking indicators is 81% and belongs to the high category, because of the teacher's role in directing students to be able to improve their critical thinking skills and the characteristics of critical thinking skills that each student has.

Abstract

Critical thinking skills are thinking based on facts, which are meaningful, as well as thinking based on goals and reasons. Critical thinking skills are used in developing ideas from a problem. Critical thinking skills that have been studied so far are only limited to knowing whether or not the influence of the learning model on critical thinking skills at certain levels of education. No research has been found that examines the tendency of various learning models and levels of education in improving critical thinking skills. The research objectives are: (1) to determine the potential of the learning model in improving critical thinking skills, (2) to determine the factors that influence the strength or weakness of the learning model on critical thinking skills. This type of research is a meta-analytical survey of quasi-experimental research, learning model as the independent variable and critical thinking skills as the dependent variable. The data analyzed were 50 studies consisting of 2 articles, 12 theses, 29 theses, and 7 dissertations. The results showed that 47 studies had an effect on improving students' critical thinking. Most studies use innovative learning models in improving critical thinking. The learning model contains a learning syntax that contains strategies to improve critical thinking skills. The conclusion of the research is that most of the learning models in improving critical thinking skills are innovative learning models. Other factors that influence critical thinking skills are syntax excellence, teacher's ability to teach, condition, and students' intelligence.
