Abstract
The COVID-19 pandemic has forced schools to make a shift in learning mode, from face to face become online remote learning. This is also faced and done by chemistry teachers. The study was conducted to investigate the response of chemistry teachers to online learning in the COVID-19 pandemic. A purposive survey method was used in this study by giving online questionnaires through Google form containing 10 open questions about chemistry learning and practicum conducted by the chemistry teachers in the COVID-19 pandemic. The data were collected for a week at the beginning of June 2020. A total of 55 chemistry teachers from West Java participated as respondents. The result found that chemistry teachers had tried to utilize various technology platforms in conducting learning. Moreover, most of them faced difficulty to arrange the lab-work activities and did nothing. Some teachers try to find lab-work multimedia instead of real activities. However, the multimedia commonly did not make students pertain the processes skills. Since the pandemic could not be predicted when it will finish, this is a kind of challenges and opportunities to think about implementing online chemistry learning from now and then.

Authors: Romika Y , Atun S 
Published: March 2021

Abstract
Self-efficacy is described as an individual’s beliefs about their abilities to complete an action. It is a part of the social cognitive theory in the chemistry learning process. self-efficacy consists of six aspects, namely the choice of activities, effort, perseverance, learning, achievement and strategy orientation. The objective of this study was to develop an instrument of chemistry student virtual Laboratory self-efficacy (CSVL-SE) in a virtual laboratory within the chemical equilibrium topic. This research used research and development (R&D) method. The data was obtained through a self-efficacy questionnaire. The expert confirmed the content validity with 26 items that had been administered to 60 students in senior high school. Rasch Model used to analyse the data that met the unidimensionality, item fit, difficulty or ability estimation, reliability, and information function. The findings showed that 26 items match into the Rasch Model with reliability person and reliability item of 0.84 and 0.97. So that, this instrument is appropriate to collect the data.

Published: March 2021

Abstract
The purpose of this study was to identify the effects of practicum using inquiry-based laboratories of enzyme kinetics on local material to improve students’ critical thinking ability. The inquiry-based laboratory practice of enzyme kinetics has four stages to keep the students’ effort on track: pre-lab activities, an in-lab discussion, in-lab work and a post-lab assignment. This study used a quasi-experimental method, with single group pretest-posttest design. The subjects of this study involve 55 students enrolled in biochemistry practicum course from the sixth semester of chemistry study program. The critical thinking ability test instrument consist of 12 reasonable multiple choices question that includes two indicators of critical thinking ability i.e. basic support and inference and also supported by student worksheet. Data analysis of students’ score test using t-test. There was a statistically significant improvement of students’ critical thinking skills (symp.sig 0.000). Furthermore to see the increase in each students’ critical thinking indicator, N-gain is calculated. Based on implementation of the inquiry-based laboratory, it is reported that students’ critical thinking skills improved in medium category and also for students’ critical thinking indicator of ‘inference’. But in the students’ critical thinking indicator of ‘basic support’ they get high category.

Published: March 2021

Abstract
Prescription screening is an assessment of the suitability of prescriptions performed by pharmacies in order to minimize the occurrence of medication errors. It is necessary to use information technology so that prescription screening can be carried out quickly, precisely and accurately. The purpose of study was to develop a design model for prescription screening management information systems in Puskesmas Kotagede 1. This study was a descriptive study with a cross sectional design. The research was conducted at the outpatient pharmacy installation at Kotagede 1 Public Health Center in November 2019-April 2020. To determine the system requirements analysis, a descriptive analysis was carried out. The development of a prescription screening information system was carried out using the prototype method. The results of the system requirements analysis indicate that the identification of prescription screening has not been carried out completely by pharmaceutical officers. The development of a prescription screening information system model design at Puskesmas Kotagede 1 uses the waterfall method. The stages start from requirement analysis, system design, implementation, integration & testing, operation & maintenance. With the development of a prescription screening information system model, it can facilitate pharmaceutical work in the prescription screening process to be fast, precise and accurate.

Published: March 2021

Abstract
Map-based visualization of land ownership data is much needed by policymakers, both in government and private institutions. The utilization of this data is primarily to support macro planning, policy-making, and good governance. On the other hand, there are currently many application systems available which are the RDBMS database. This research examines the proposed RDBMS integration model and Google Maps maps to visualize land ownership data in a dynamic map view. The prototyping method is applied in this study to show how the available RDBMS can be improved to visualize land ownership data in a WebGIS-based application. The proposed model is tested using an application prototype. Technically the model can be implemented without significant constraints, but the actual implementation still faces obstacles, especially related to policies related to the cross-sectoral utilization of population databases and the obligation to maintain data confidentiality.

AbstractThe spread of the Covid-19 virus continues to increase, so it is necessary to take preventive measures through increasing public awareness of the implementation of the COVID-19 prevention health protocol. Raising awareness can be done through socialization starting from the dangers of civid-19 and implementing standards for the prevention of covid-19 health protocols. The method used can be through the lecture method through online meetings. the media that can be used are the material of the dangers of covid-19, and the health protocol for the prevention of covid-19 according to the standards of the Ministry of Health of the Republic of Indonesia. evaluation is carried out by providing a questionnaire before and after socialization activities. The results of the socialization show a significance of 0.000, which is less than the significance level (a) of 0.05. These results mean that there is a significant difference between awareness of the dangers of covid-19 and health protocol care behavior before and after socialization. The t table shows that the t count is negative, namely 7.844, which means that the average before was lower than after the socialization was carried out.
