Abstract

As it has been widely known that the spectacular characteristics of nanomaterials are strongly dependent on their particle size, crystal structure, and molecular arrangement. The fine structure formation of nanomaterials is inevitable in an attempt of optimizing their promising applications in various fields. One of the notable nanomaterials up to now is hausmannite or Mn3O4. This paper presents a combination of coprecipitation and sonochemical routes in a concurrent way to produce spinel-structured hausmannite nanomaterials. The pH was varied during the synthesis at values of 9, 10, 11, 11.5, and 12. The crystal structure properties were evaluated by X-ray diffractometry (XRD) with the diffraction angle range of 15° - 80°. The functional groups were investigated by Fourier transform infrared (FTIR) spectrometry having wavenumber from 400 to 4000 cm-1. In this study, pH 10 was found to be the best synthesis parameter in producing Mn3O4. Both XRD and FTIR data analyses have agreed on the formation of spinel hausmannite nanomaterials.

Abstract

The purpose of this study was to design scaffolding that is connected to an ICT system (e-scaffolding) which was implemented with blended learning to improve students’ physics problem solving skills (PSS). The research method used is Borg & Gall research method and the effectiveness test used is T-test in analyzing whether there are differences physics PSS in the experimental and control classes. This article describes scaffolding systems that focus in procedural types which using prompt questions and facts found during the implementation of this product. The results showed that the developed e-scaffolding was appropriate to be used for several examinations after being evaluated by experts and practitioners. In a limited implementation, e-scaffolding has proven not to be out of the social constructivist scope and adapted to the actual abilities of students. At effectiveness test, e-scaffolding is able to connect between students in solving problems both in synchronous and asynchronous collaboration. In addition, e-scaffolding is able to split problem categories that students are experts and beginners, giving shape to performance and increasing students’ physics PSS. So, it can be concluded that e-scaffolding has been successfully developed. Suggestions for further research have been presented in this article.

Abstract

This research explores high school students' problem-solving abilities based on gender in a static and dynamic fluid material. The type of research is quantitative descriptive research design. The population of this research was class XII students at one of the state schools in Malang, East Java. The sampling technique was purposive sampling, which was done by selecting students taught by the same teacher. The selected sample consisted of 115 students, 34 males and 81 females. The data in this study was collected by giving a test, where the test instrument used was seven essay questions on fluid material, which had a reliability coefficient of 0.70 (high). The data obtained was then analyzed using descriptive statistics, t-test, and the ANOVA test. The research results show differences in problem-solving ability between male and female students, where female students have higher problem-solving ability than male students in all problem-solving processes. The physics approach is the highest process mastered by students, while the mathematical procedure is the lowest. A physics problem-solving process is still in the low category, indicating that efforts are needed to improve students' problem-solving ability.

Abstract

This research aims to develop an instrument for assessing understanding distance and displacement concepts. Distance and Displacement Inventory (DDI) is an instrument constructed in multi-representations, including picture, table, graphic, mathematical, and verbal representations. This instrument is in multiple-choice format with ten questions to assess students' understanding of distance traveled and displacement. DDI development refers to R&D design by Borg&Gall and test development flowchart by Beichner. DDI was applied to 357 students in Indonesia who had taken introductory physics courses. Student answers were analyzed to determine the DDI's psychometric properties and structural analysis. The analysis results show that the DDI is adequate for assessing students' understanding of travel distance and displacement concepts. Meanwhile, the structural analysis of students' knowledge results shows that students have different perceptions of each question item according to their representation. Furthermore, students who understand the concept of distance traveled and displacement in one representation may need help understanding it correctly in another representation. This research implies the necessity of designing learning designs based on multi-representations and teaching students about the changes between these representations.

Abstract

Single garlic is known to have many benefits as an alternative therapy for various types of metabolic syndrome. The bioactive compounds, allicin and alliin, in garlic are unstable and easily degraded in digestion. Chitosan-alginate microencapsulation is thought to increase stability and protect active compound so its therapeutic effect is more optimal. This study aimed to characterize the microencapsulation chitosan-alginate of single garlic extract (MCA- SGE), as well as to examine the antioxidant activity and kinetic release of MCA-SGE in vitro. The research procedure includes the steps of single garlic extraction, preparation of MCA-SGE, characterization of MCA-SGE (PSA, SEM, and FTIR) as well as biological testing of MCA-SGE through antioxidant activity and kinetic release tests. PSA results showed the mean particle size of MCA-SGE was 439.0 ± 1.9 nm or 0.4 m with a polydispersity index (PDI) value of 0.579 ± 0.046 and a zeta potential value of 15.4 ± 0.3 mV. The SEM results showed that the morphology of MCA-SGE was spherical with a smooth surface and a micrometre size of 0.4 - 0.7 µm. The FTIR results describe a shift in absorption and addition of SGE functional groups after encapsulation. The results of the antioxidant activity test showed the antioxidant activity of MCA-SGE was 65%, while SGE was 55%. The results of the kinetic release showed that more allicin and alliin were released by SGE than MCA-SGE during the 4-hour kinetic release simulation. MCA-SGE has the potential to be used as a drug delivery system with controlled release.

Abstract

In an effort to utilize the potential of Moringa leaves in Sumenep Regency, this service team proposes marketing of Moringa leaf products based on considerations from RIRN 2017-2045, RENSTRA UM, and KAPUS PHIKA LP2M UM. [Situation analysis] Moringa tree is a type of plant that is very easy to breed, grow and cultivate on community land, either in fields, gardens, the edges of rice fields and people's house yards. Moringa plants have many benefits that are spread in every part, ranging from leaves, seeds, stems, and roots. Moringa plants are able to overcome nutritional deficiencies and various health problems because they have a high nutritional content. Moringa also has potential as a raw material for medicines, cosmetic industry and environmental improvement from pollution with a high level of market demand. [Partner problems] Currently, partners need synergy to utilize the potential of natural materials for farming purposes (local resources), fruit farmers experience crop failure due to the drastic climate. [Solution] The UM service team offers a solution in the form of socialization and assistance for Moringa products, namely MOLP based on Green House agriculture. [Objective] The main objective in this service activity is to establish partnerships to take advantage of available business opportunities (utilization of Moringa leaves) and assist farmers' complaints regarding weather problems, in order to meet local and foreign market demands. The results of this service activity are expected to make Moringa plants a source of income for the people of Sumenep Regency (the supplier of MOLP). Furthermore, it is also expected to be able to increase synergy with the government in order to build domestic food security. [Method of implementation] This service activity will be carried out through a process of observation, planning, mentoring, and socialization.
