Metode Pemicuan dalam Upaya Meningkatkan Budaya Pemberantasan Sarang Nyamuk (PSN) pada Masyarakat

This study aims to produce a triggering method to improve the culture of eradicating mosquito nests (PSN) in the community. The method used is quantitative research with research and development (R&D) design. The research results show that the PSN Mobile Triggering education model, namely the field triggering model followed by Android-based triggering, was declared feasible after the validation stage with 100% health promotion experts, 94.55% IT experts, 92% educational technology experts, and 80 practitioners. % and 93.85% one-on-one trials, 95% small group trials, and 96% large group trials. The PSN Mobile Trigger product effectively increases household mosquitoes' knowledge, attitudes, and behavior by up to 100% in eradicating mosquito nests. In conclusion, the educational model is feasible and effective to use to increase the knowledge, attitudes, and behavior of Jumantik Rumah in destroying mosquito nests.

OPTIMIZATION OF SELF-NANOEMULSIFYING DRUG DELIVERY SYSTEMS OF LEMONGRASS (CYMBOPOGON CITRATUS) ESSENTIAL OIL

Objective: Focus of this study was to optimize and to characterize the self-Nano emulsifying drug delivery system using lemongrass (Cymbopogon citratus) essential oil.Methods: The optimum formulas were analyzed using a D-Optimal mixture experimental design and performed using a Design Expert® Ver. 7.1.5. Formulation variables which include in the design were: oil component X1 (a mixture of Cymbopogon citratus essential oil and virgin coconut oil/VCO), surfactant X2 (Tween 80), and co-surfactant (PEG 400), while emulsification time in a sec (Y1) and transmittance in percent (Y2) as responses.Results: The optimum formula for SNEDDS in the current study were: Cymbopogon citratus essential oil (7.147%), VCO (7.147%), Tween 80 (71.417%), and PEG 400 (14.290%). From the optimizing formula can be shown that the mean of droplet size, polydispersity-index, zeta potential, and viscosity were: 13.17±0.06 nm, 0.17±0.05,-20.90±1.47 mV, 200±0mPa. s (n=3), respectively. Furthermore, the optimized formula has passed the thermodynamic stability test; meanwhile, transmission electron microscopy displayed spherical shape.Conclusion: The optimized SNEDDS formula was improving solubility of poorly soluble Cymbopogon citratus essential oil

COMPARING MODEL-BUILDING PROCESS: A MODEL PROSPECTIVE TEACHERS USED IN INTERPRETING STUDENTS’ MATHEMATICAL THINKING

Mathematical thinking is an important aspect of mathematics education and, therefore, also needs to be understood by prospective teachers. Prospective teachers should have the ability to analyze and interpret students’ mathematical thinking. Comparing model is one of the interpretation models from Wilson, Lee, and Hollebrands. This article will describe the prospective teacher used the model of the building process in interpretation students' mathematical thinking. Subjects selected by considering them in following the students’ strategies in solving the Building Construction Problem. Comparing model is a model of interpretation in which a person interprets student thinking based on student work. There are two types comparing model building process prospective teacher use in interpreting students’ mathematical thinking ie. comparing work and comparing knowledge. In comparing works, prospective teachers use an external representation rubric. This is used to analyze student activities in order to provide an interpretation that is comparing the work of students with their own work. In comparing knowledge, prospective teachers use internal representation rubrics to provide interpretation by comparing the students' work with their knowledge or thought

Live weight uniformity on the day-old chick of Indonesian local chickens

The uniformity of live weight in the early stage (DOC) is an indicator applied to evaluate the quality of brooding, raising, and growth management. This study aims to compare the live weight uniformity of DOC in three local breeds as a parental group, namely Merawang A and B (n:196), Murung Panggang (n:157), and KUB (n:416), as well as in five groups of Bulaksumur (BS) for crossbred group, namely BS-1 (n:136), BS-2 (n:76), BS-3 (n:106), BS-5 (n:81), BS-6 (n:164). The live weight data of DOC was obtained in Gunungkidul Regency under similar management. The results show that the BS groups had higher live weight (31.9 g ± 3.1) compared to Merawang A (24 g ± 3.1), Murung Panggang (28.2 g ± 2.3), and KUB (28.1 g ± 2.8). Furthermore, the live weight uniformity on the BS DOC averaged 71% across all groups, with the highest uniformity being BS-3 (87%). Murung Panggang had a higher live weight uniformity (82%) compared to Merawang A and B (42%, 64%) and KUB (63%). The average coefficient variance was less than 10%, except for Merawang A and BS-2 with 13.09% and 11.35%, respectively. In conclusion, the DOC of the crossbred (BS) was more uniform than its parental groups. However, to distinguish the significantly different in the chicken live weight in early stage, further analysis needs to be conducted in the future

ANALYSIS OF SOCIO ECONOMIC FACTORS THAT INFLUENCE COFFEE BUSINESS INCOME IN DONOWARIH VILLAGE, KARANGPLOSO DISTRICT, MALANG REGENCY

ABSTRAKThis study aims (1) to determine the income and efficiency of coffee farming and (2) to determine the socio-economic factors that affect the income of coffee farming. This research was conducted in Donowarih Village, Karangploso District, Malang Regency and carried out in January - March 2021. The selection of research locations was carried out purposively. The sampling method was carried out using the Simple Random Sampling method with the Slovin formulation, so that 41 coffee farmers were taken as samples. The data analysis method used is efficiency analysis and Cobb Douglas profit function analysis with Unit Output Price (UOP) technique. Based on the results of research in Donowarih Village, Karangploso District, Malang Regency, it shows that the average coffee farming income per hectare is Rp. 9,901,960 while the value of the R/C ratio is 3,30, which means that coffee farming is efficient and profitable. While the socio-economic factors that affect the income of coffee farming are land area, the price of ZA fertilizer, the price of phonska fertilizer, and the price of medicine.Keywords: coffee farming; efficiency; Socio-economic factorsABSTRAKThis study aims (1) to determine the income and efficiency of coffee farming and (2) to determine the socio-economic factors that affect the income of coffee farming.
