Abstract

Each student has differences in problem-solving, scientific literacy, and higher-order thinking skills. Gender differences partially influence student mindset. The purpose of this study was to analyze the problem-solving skill and scientific literation of students on different genders. The study adopted and modified the one-shot case study design. The subjects of this study were 76 students who took the Animal Ecology course. Both experimental classes were given treatment using practical activities. Data on students' problem-solving skill were collected by using a test consisting of 25 questions. Whereas scientific literacy was collected by using essay questions. Students’ scientific literacy were categorized into 5 scales that were analyzed by using percentages. Statistical analysis uses descriptive and t-tests to determine differences in problem solving skill on different genders. The results showed that (1) 37.66% of students’ scientific literacy are on a multidimensional and conceptual scale, while the remaining 62.34% were on a functional, nominal and literacy scale, (2) students' problem-solving skill are in the medium category, and there is no difference in problem-solving skill in males and females (p>.05).

Abstract

The harmful effects of exposure to light (UV) can be prevented by using sunscreen. This study aims to determine the best formulation contained in various herbal plants to be used as a manufacturing material sunscreen. The method in this study is the study of literature from the research journal database on the internet, namely through google scholar and Proquest University of Mataram. Sunscreens are assessed in terms of light protection factor expressed by the SPF value (Sun Protection Factor) to determine the effectiveness of sunscreen preparations or the ability to withstand UV rays. Several types of herbal plants that grow in various regions in Indonesia contain photoprotective bioactive compounds. Aromatic ginger (Kaempferia galanga L.) is a herbal plant widely used as an ingredient in sunscreens with a high protection category. Cinnamic derivatives, namely ethyl para-methoxycinnamate (EPMS), are one of the compounds contained in aromatic ginger and can be used as a manufacturing material sunscreen that is good and safe for the skin.

Abstract

Leneng River is one of the rivers in Praya City, Central Lombok Regency, which receives domestic, agricultural, and household industrial waste. Various community activities along the banks of the Leneng River have affected river water quality. Some communities on the banks of the Leneng River, from upstream to downstream, still use river water for their daily needs. This study aims to 1) analyze the water quality of the Leneng River in terms of environmental parameters (Physical, chemical, and biological) and 2) Determine the level of pollution of the Leneng River water using the Pollution Index (IP) method. River water quality measurements were carried out at 3 (three) sample points. Parameters measured and observed were physical parameters, namely Total Solid Suspend (TSS); chemical parameters, namely pH, Total Phosphate (T.PO4), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Dissolved Oxygen (DO), and biological parameters namely Total coliform and Fecal Coliform. This type of research is survey research with a quantitative descriptive approach. The results showed that the TSS value at sample point 1 (upstream) exceeded the required quality standard; the highest TSS concentration value was 54 mg/L, and the lowest at sample point 2 (middle section) was 2.50 mg/L. Value parameter concentration pH 7.7-8.7, T.PO4 value 0.05 mg/L-0.29 mg/L, BOD value 0.17-0.42 mg/L, COD concentration value 8 mg/L -9mg/L, and DO value of 6.07 mg/L-7.57 mg/L, this shows that the concentration for chemical parameters still meets the class I water quality standards according to PP 22 of 2021, while the total coliform parameter value and Facel coliform have exceeded class I water quality standards. The total coliform concentration value is 10,000 - 20,000 MPN/100 mL, and the Fecal coliform value is 600 MPN/100 mL – 2,500 MPN/100 mL, while based on the Pollution Index (IP) quality status water in the upstream with a value of 2.84, the middle part of 1.97, and the downstream part of 2.84, this shows a decrease in water quality from upstream to downstream of the river, with a level of pollution in the lightly polluted category.

Abstract

Research This aims to develop practicum module for making soap with natural active ingredients to improve students' creative thinking skills. Practicum instructions will be applied to natural science and natural product chemistry practicum courses to provide innovations and appropriate technology for science education master students. The development of practicum instructions is a Research and Development (R & D) development with a define, design, develop, and disseminate (4D) model. The samples of this research were chemistry students and Master of Science Education students. The tests carried out were tests of physical properties (organoleptic, pH, and homogeneity) and antimicrobial tests with varying concentrations of trimyristin. Products in the form of practicum module are validated. The results showed that the validity value of the three validators obtained using the Aiken index was V = 0.84, which indicated that the natural science practicum module: the procedure for making trimyristin soap from nutmeg, was very valid and feasible to use. Meanwhile, practicality can be seen from the responses of students and lecturers, who show a positive response with average practicality of all components of 88% of student responses and 89% of lecturer responses. The results of the physical evaluation of trimyristin solid soap (organoleptic, pH, foam stability, and moisture content) produced from this study showed good results because they met several standards for the quality of solid soap SNI 3532-2016. Based on these data, the materials chemistry practicum module: procedures for making trimyristin soap from nutmeg seeds to support meaningful learning that is developed is very valid and very practical to use in the learning process

Abstract

The people of NTB have many distinctive cultures and cuisines. The use of plants is traditional medicine. This study aims to develop practical guidelines based on the medicinal plant sasambo, NTB. Development design is Research & Development with a 4D model (define, design, develop, and disseminate). The results of laboratory experiments are outlined in practicum guidelines for student activities. Chemistry lecturers in chemistry and natural product chemistry constructively validate the procedures. The analytical method uses Aiken's V formula and percentage agreement. The results of the expert validation show that the practicum guidelines meet very valid criteria with an Aiken value of 0.86. The guidelines also received positive responses from students and expert validators with an average practicality level of 88.6% with very practical criteria. Guidelines can be applied to learning with a percentage agreement of 100%. The cultural richness applied to learning can increase motivation learning and encourage students to be creative in developing products from the Sasambo milk medicinal plant.
