Abstract

The research conducted aims to formulate and assess the feasibility of the Student Worksheet (LKPD) based on science literacy on the topic of environmental pollution, specifically water pollution, which can be used to develop students' knowledge about environmental pollution. The quality of the Student Worksheet refers to the criteria of validity, readability, and student responses to the Student Worksheet. This study uses a research and development (R&D) method with a 4D model consisting of stages: Define, Design, Development, without involving the Disseminate stage. Data collection was carried out through preliminary studies in the form of interviews, material and media validation questionnaires, as well as readability and student response questionnaires. The sequence of data analysis stages includes expert validation, readability testing by subject teachers and students, and student response questionnaires. This research was conducted at MA Negeri 1 Kota Bandung involving 16 students and 1 Biology teacher. The research results show that the developed LKPD is worthy, with a score of 72.66% from the material expert and 85.75% from the media expert, both of which fall into the eligible and very eligible categories. The overall average readability scores from the subject teacher and students were 80% and 91%, respectively. The response results from the students obtained a score of 89.16% with a very good interpretation. Thus, the developed LKPD can be used and supports the learning process in the classroom.

Abstract

The high yield gap between the potential of varieties and the real production of corn in the field is one of the problems in meeting the national corn needs, so various efforts to increase productivity are continuously carried out, one of which is the application of inorganic fertilizers that are suitable for plant needs and specific. The study was conducted at KP Mojosari AIAT East Java from November 2020 to February 2021. The experiment used a randomized block design (RAK) with 5 replications and 6 treatments including control (without fertilizer) and 5 other treatments which were a combination of the dose of ammonium chloride fertilizer and the dose of urea fertilizer. The results showed that treatment F showed the highest yields on plant height and canopy width, treatment E showed best results on leaf width variables, and treatment C showed the highest results on stem diameter variables. Meanwhile, result parameter shows that all treatment combinations obtained higher results than the control. The conclusion is that this ammonium chloride fertilizer can be used for corn because it has an additional Cl element which is useful for the efficient use of nitrogen in plants, but the application of Cl must be limited

Abstract

Background Schools and formal education can be a bridge for airborne disease to spread caused by air germs. Measurement of air germs result, shows that class 4 (9482 CFU/m3) and class 5(2371 CFU/m3) in SDN 5 Teluk, Purwokerto Selatan district.  The average air gems rate is 1685.33 CFU/m3 in SDN Karangmangu, Baturaden district. The aims of this study was to analyze predictive factors for air germs number in public elementary schools in Banyumas Regency. Methods This research is observational study with cross sectional analytic approach. The independent variables or predictive variables are temperature, humidity, lighting, occupancy density, occupant behavior, cleaning frequency, and ventilation area. The dependent variable is the number of air germs. The sample size was 46 classrooms. The analysis used simple and multiple regression. Research Resulth average temperature (29.9130C), humidity (74.087%), lighting (225.304 lux), occupancy density (2.050 m2 / person), cleaning frequency (2.5 times / day), occupant behavior (53.470% active), ventilation area (9,171%), air germ rate (3425,130 CFU / m3), wind speed (not detected by tools). Prediction of temperature with the number of air germs, Y = 1026.505 + 80.187 X, R = 0.169, p = 0.262. Prediction of humidity with the number of air germs, Y = 2719.038 + 9.531 X, R = 0.083, p = 0.585. Prediction of exposure with air germ count, Y = 3343.684 + 0.361 X, R = 0.059, p = 0.696. Prediction of occupancy density with air germ numbers, Y = 3959.041 + (-260.389) X, R = - 0.386, p = 0.008. Prediction of cleaning frequency with air germ count, Y = 3204.664 + 88.187 X, R = 0.150, p = 0.320. Prediction of occupant behavior with air germ count, Y = 3632.488 + (-3.878) X, R = - 0.160, p = 0.289. Prediction of ventilation area with air germ count, Y = 3965.421 + (-58.911) X, R = -0.427, p = 0.003. Simultaneously predict temperature, humidity, lighting, occupancy density, cleaning frequency, occupant behavior and ventilation area with air germ count, Y = (-1267.495) + (-194.907) (density p = 0.049) + (-42.019) ( Ventilation p = 0.061) + 148.449 (Temperature p = 0.072) + 90.826 (Cleaning p = 0.379) + 12.187 (Humidity p = 0.543) + (-2.205) (Behavior p = 0.561) + 0.111 (Exposure p = 0.913), R = 0.5850. Conclusion ,  predictive factors for occupancy density, ventilation and temperature are significant in predicting the number of airborne germs. Suggestions need to regulate the number of students in each class, the availability standard ventilation, and the addition of an Exhauster.

The research discussed how implementing information services in schools was viewed from the CIPP model. The study used descriptive qualitative methods, and the data analysis techniques used in this research were data reduction, presentation, data and conclusions. Input preparations made by BK teachers before implementing services include distributing AKPD, compiling RPL, and providing media and techniques/methods. Process information services were carried out through classical guidance, guidance boards and social media. Product evaluation was carried out in several ways, including questions that were asked directly and randomly appointed. Then, students provided conclusions on sheets of paper and, finally, through the quiz application. From the evaluation results, students can understand the material well, and if the counseling teacher randomly appoints them, students can explain according to their understanding
