Kunyit putih banyak mengandung zat aktif yang dimanfaatkan sebagai obat tradisional. Tujuan dari penelitian ini adalah untuk mengisolasi dan menentukan jenis zat aktif dari ekstrak metanol rimpang Kunyit Putih (Curcuma mangga Val) fraksi etil asetat serta menentukan kadar zat aktifnya. Sebanyak 1000 g kunyit putih halus dimaserasi dengan pelarut metanol pada suhu kamar selama 24 jam, disaring dan diulangi sebanyak 7x. Ekstrak metanol tersebut dipekatkan kemudian difraksinasi menggunakan etil asetat. Ekstrak etil asetat kental yang didapat sebanyak 39,05 g dipisahkan dengan Kromatografi Kolom Gravitasi (KKG). Senyawa hasil isolasi menggunakan KKG sebanyak 0,035g. Berdasarkan kesamaan dalam spektra UV-Vis dan GC-MS maka diduga senyawa zat aktif yang ada dalam ekstrak metanol kunyit putih fraksi etil asetat adalah senyawa Labda-8(17),12-dien-15,16-dial dengan kadar sebanyak 0,00149%.

The objectives of this research are to identify whether the bioactivecompound of methanol fraction extracts of Sargasum sp can be used as anti hepatotoxic and to determine the dose of such compound in order that it may be used as anti hepatotoxic. The population used in this research was 2-month male white rats with almost similar weight. 39 rats were taken for the samples. Treating CCl4 injection carried out the bioactive compound activity test and the treatment of these compound extracts was observed by examining the liver cell damage microscopically and analyzing the GPT content. Examination was a/so conducted to the control rats (without CCI4 injection and bioactive compound treatment). From the result of the research it can be concluded that methanol fraction extract of Sargasum sp may be used as anti hepatotoxic. It wasfound that the bioactive compound activity appeared at the dose of 500 mglkg of weight with 5 times treatments.

SCIENCE WEB MODULE BASED ON GUIDED INQUIRY TO IMPROVE THINKING SKILLAbstractThe science web module is a systematically structured teaching material to achieve electronic learning objectives using website applications in which writing, animation, video, and navigation are exciting, interactive, active, and motivating learning that can facilitate students' thinking skills. Guided inquiry is a model that trains students to be actively involved in investigations with questions raised by teachers to direct students to find concepts. Guided inquiry-based web modules are used to improve students' thinking skills measured through written tests. This study uses a pretest-posttest control group design. Based on the results of the analysis using the Kruskal Wallis test, there are differences in the experimental class using the science web module based on guided inquiry and the control class using the science teaching materials commonly used by teachers. The results showed an increase in higher thinking skills in the experimental class than in the control class, resulting in the high effect size category so that the experimental class increased the thinking skills more effectively than the control class.

In higher Education, Graduate Students have a special characteristic of the learning process. Especially in the new normal era, Higher Education needs the best learning model that fits and comfortable for graduate students. This study aims to examine the effectiveness of Blended Learning with Peer Tutor (BL-PT) for graduate students in the new normal era, especially on the aspect of motivation and service satisfaction. It is descriptive quantitative research with the random sampling technique. In addition, this study also examined whether the level of satisfaction had an effect on student motivation in learning in the new normal period. There were 43 Graduate Students from Graduate School Program, Yogyakarta State University as participants in this study. The technique of data analyses was used comparative-descriptive and paired sample t-test using SPSS 24. The study reveals: (1) The BL-PT model has a positive impact on students motivation and service satisfaction of Higher Education; (2) there is not a significant difference in students motivation of male and female graduate students; (3) there is no significant difference of students service satisfaction level after learning with BL-PT. Learning with the BL-PT model can be an alternative for policymakers, Higher education Institution, and lecture to solve the learning model that fit and comfortable with graduate students in the New Normal Era

Curcuminoids are the main component found in many Zingiberaceae family plants. The aim of this study was to characterize curcuminoid and its activity test as an antioxidant and antibacterial. Dryed powder of C. xanthorrhiza (1 kg) was macerated with ethanol for 24 hours at room temperature. Ethanol extract of C. xanthorrhiza was subsequently fractionated with n-hexane and chloroform to take the yellow or orange indicated contain of curcuminoids. Analysis of total phenolic levels was carried out by the Follin-Ciaocalteau method. The isolation of curcuminoid componens from this fraction was carried out by chromatographic method and the structure elucidation was performed by interpretation of spectroscopic data, including UV, IR, 1H and 13C NMR 1D and 2D. The antioxidant activity test used the DPPH (2,2-diphenylpicrylhydrazyl) method, while the antibacterial activity test used Kirby Bauer test diffusion method. The results showed that the curcuminoid fraction yield was 10.06% from ethanol extract C. xanthorrhiza. The total phenolic content of curcuminoids fraction was 745.45 ± 18.5 mg galic acid (GA)/g extract. Curcuminoids fraction was isolated a known compound desmethoxycurcumin (1). The content of demethoxycurcumin (1) in curcuminoid fraction is 20.97 %.The antioxidant activity of curcuminoids fraction showed strongest activity with IC50 24.98 µg/ml. Antibacterial activity against of the four pathogenic bacteria showed medium activity. The study suggests that curcuminoids extract from C. xanthorrhiza rhizome have potential compounds could be suitable for antioxidant and the treatment of various infections caused of microbial.

Science and religion are closely related because they come from one source, namely God Almighty. Therefore, the concept of the integration of science and religion must be implemented in the form of integrating religious characters in the science learning process. This study aims to identify and inventory the learning methods used to integrate religious character values in chemistry learning. This research is conducted by reviewing the literature, both in books, journal articles and popular scientific writings, about methods of integrating religious character values in chemistry learning. The main data sources are from journal articles that discuss the integration of religious characters in chemistry learning. The journal articles that became the main data source were ten articles obtained from the Google Scholar website using the keyword "integration of religious characters in chemistry learning". The research data were analyzed descriptively and qualitatively. A critical study was also carried out on the literature to obtain the correct conclusion. According to the teacher's creativity, the study results concluded that religious character values can be integrated in chemistry learning in various ways/methods. However, in their article, the researchers did not clearly and unequivocally mention the name of the learning method used to integrate religious characters in chemistry learning. Based on this conclusion, it is recommended that other research is needed to develop a learning model that integrates religious character values in chemistry learning.
