Abstract

Physics learning using direct instruction method or speech method did not optimal in increasing concept mastery. This case results in low learning outcomes due to the low mastery of students' physics concepts. The solution to this problem is to develop learning instruments based on a cognitive conflict approach assisted by lesson videos to improve students' mastery of physics concepts as valid and appropriate products for use in learning. The learning tools developed are syllabus, lesson plans, Student’s Worksheet, lesson videos and concept mastery assessment instruments. The kind of research is research and development with the 4D method (define, design, develop, disseminate). This research is limited to the development stage, which includes validity testing. The results of this study can be concluded that the learning tools in the category are very valid and reliable. Based on these results, the learning tools developed are suitable for use in learning.

Abstract

Medical waste from dental practice is harmful to life and the environment. Previous studies reported that the total medical solid waste generated by dental practices in Pekanbaru City was 4.62 kg/day with an average of 0.3 kg ± 0.07 kg/day. Based on the type of waste generated, 69% is infectious waste, 27% is toxic waste, and 4% is radioactive waste. The purpose of the study was to analyze the medical waste generated and the environmental costs incurred by dentists using several scenarios of medical waste management policy intervention. The method used is a simulation model with a dynamic system approach. Simulations were carried out from 2018 to 2047. The results of the study obtained a percentage reduction for 30 years, it was found that the combination of providing training and cooperation with the waste management party had the largest decrease of 41.9%. The biggest decrease in environmental costs was the combined scenario of 99.69%, followed by the 99.62% cooperation scenario and 19.5% training. The most effective self-care solid medical waste management model is the scenario 3 model because it can reduce the waste generated and also reduce costs.

Abstract

The Community-Led Total Sanitation Program is an approach to change sanitation hygiene behavior through triggering activities, which has not yet achieved the national target. This study aimed to analyze the implementation of the Community-Led Total Sanitation Program in a sustainable environment in a suburban settlement. This was a qualitative study with an action research approach in three districts in the Siak River suburb. The participants of this study were residents who lived on the banks of the Siak river and the holders of the Environmental Health Program at the Public Health Center. Data were collected through direct observation and in-depth interviews regarding the Open Defecation Free (ODF) program, handwashing with soap, household food and beverage management, household waste management, and household liquid waste management. This study found that the community-led total sanitation program in the suburban of the three sub-districts of the city of Pekanbaru was not well implemented yet, especially in the ecological aspects of the Open Defecation Free (ODF) program, waste management, and liquid waste management program. Economically, the implementation of the program by non-governmental organizations had not been supported. Socially, health workers and community leaders provided education related to environmental sanitation and obtained a level of interpretation above 70%.

Abstract

Currently, there are still many people who are not aware of their disaster-prone areas. This is exacerbated by the lack of maximum community empowerment in disaster prevention and management. This study aims to determine the effect of the implementation of community-based disaster risk reduction (CB DRR) on the knowledge and skills of the community in disaster mitigation. This research is a quasi-experimental study, with a non-randomized control group pre-test - post-test design. The population and sample in this study were all community administrators who were aware of the disaster. The instrument used is a questionnaire that has been tested for validity and reliability. Research procedures include administrative procedures and technical procedures. Data processing is done through the process of editing, coding, scoring, processing, and cleaning. Data analysis techniques include univariate analysis, bivariate analysis (paired t-test), and multivariate analysis (General Linear Model Repeated Measure or GLM-RM). The p-value on the knowledge and skills variables were both 0.000 (<0.05). The value of the Greenhouse-Geisser sig analysis on the knowledge and skills variables has the same p-value of 0.000 (<0.05) or there is a difference in the average knowledge and skills of respondents after being given CB DRR training. Conclusion: The CB DRR program training influences the knowledge and skills of the community in carrying out disaster mitigation with a changing trend seen from the first measurement to the last measurement.

Abstract

The potential of agriculture in Indonesia has not been fully explored. Indonesia has favorable climatic conditions, natural resources and human resources. West Nusa Tenggara (NTB) has an unproductive land area of 1.807.463 ha of the total area of NTB. One of the efforts to increase the productivity of dry land is the application of biological fertilizer. Biofertilizer that are expected to have a high contribution in increasing fertilization efficiency are Vesicular Arbuscular Mycorrhizae (MVA). MVA is important to apply to infertile soils with low nutrient content. The aim of this study was to determine the effect of MVA isolates Indegenous and media types on the growth and yield of corn plant on dry land in Central Lombok The study was carried out for 3 months using a Completely Randomized Design (CRD) with consisted of 2 factors, namely the Indegenous MVA isolate type factor with consisted of 3 levels and the planting media type factor consisting of 4 levels where each treatment was repeated 3 times so that 36 unit were obtained test. The results showed that the variety of isolates showed significant differences in all parameters of growth and yield of corn plat (plant height, root lengthand root weight). The type of planting media showed a significant difference in the parameters of root weight of corn plants. The high growth and yield response of corn plant was thought to be due to the association between corn plant and MVA which was seen in the increased plant growth in all MVA inoculated treatments with the highest plant growth in the treatment using isolate I2 (Gigaspora sp.) on the parameters observed for plant height, root length and root weight. In all parameters observed for corn  plant growth, it was found that the genus Gigaspora was superior to the genus Glomus. The best kind of planting media in increasing the growth of corn plants is a mixture of rice husk and soil biochar media with a ratio of 1:3. The use of husk and soil biochar media that was given spores of the genus Gigaspora gave the best corn plant growth

Abstract

The purpose of this study was to obtain information about the good concentration of PGPR for the growth and yield of reciprocal crosses of purple waxy corn and sweet corn (Zea mays L.), the effect of PGPR on the character of a reciprocal cross between purple waxy corn and sweet corn (Zea mays L.) and the effect of reciprocal crosses of purple waxy corn with sweet corn (Zea mays L.) on the character of maize yield. The research was conducted in Tegalgondo Village, Karangploso District, Malang Regency, East Java Province. The study was arranged in a Split-Plot Design consisting of 4 main plots (PGPR Concentration) V0 (Without PGPR), V15 (15 ml PGPR / l water), V30 (30 ml PGPR / l water), V45 ( 45 ml of PGPR/ l of water) and consisted of 4 subplots (crosses) PW (Purple Waxy Maize), PWSC (Purple Waxy Corn♂ x Sweet Corn♀), SC (Sweet Corn) and SCPW (Sweet Corn♂ x Purple Pulut Corn). ). The data obtained were analyzed using the Analysis of Variance (ANOVA) at the 5% level. If there is a significant effect between treatments, it is continued with a comparison test with a 5% LSD test using Costad software and Microsoft Excel. Based on the results, it can be concluded that there is an interaction between the administration of PGPR and the reciprocal cross of purple waxy corn x sweet corn on the observation of sugar content characters. PGPR treatment with PGPR concentration of 45 ml/l water (V45) can increase growth and yield characteristics. The results of the reciprocal crosses (PWSC) of Purple Waxy Maize x Sweet Corn and (SCPW) Sweet Corn x Purple Waxy Maize showed that the female parents were more dominant than the male parents.
