Abstract

Processing of poultry livestock waste is carried out by composting, using microorganisms and maggot as decomposers and detritivores. The aim of the study was to determine the effect of using maggot as a detritivor in the bioconversion process of various poultry wastes on C/N ratio, pH value, temperature, media shrinkage water content, and maggot biomass. The research used a Completely Randomized Design (CRD) with three treatments, P1 = broiler chicken feces, P2 = laying hen feces and P3 = quail feces and repeated 6 times. The data obtained were analyzed using variance and to see differences between treatments, the Duncan test was carried out.The results showed a decrease in the C/N ratio after the initial decomposition respectively P1 = 25.68%; P2 = 21.13%; P3 = 11.83%. Conditions of pH (4.5 – 6) and temperature of 24 – 34°C during 21 days of decomposition, in all treatments did not show significant differences, and formed the same pattern, the water content of the media after 21 days of decomposition reached 19.05 - 25, 72%. Media shrinkage and maggot biomass in various treatments showed significant differences, P3 = quail feces produced the highest shrinkage (55.1%) and the highest maggot biomass was produced in P1 = broiler chicken feces (1.620 g)

Abstract

In the 21st century, the development of information technology has made it easier to access information and supports the automation of routine activities as well as communication that can be done from anywhere. In the field of education, teachers are required to design learning media that keep up with the times. Learning media based on information technology, such as learning applications, are developed to help teachers deliver material more effectively. With that background, the researchers conducted a study aimed at developing and producing web-based learning media and analyzing its impact on improving students' static routing competence in the cognitive aspect of the Network Infrastructure Administration subject. This learning media is designed by applying the Project Based Learning model. The research was conducted using the Research and Development (R&D) method with the ADDIE development model. The trial design used is the One Group Pretest-Posttest Design. The research data was taken from the XI TKJ 1 class students at SMK Negeri 1 Sidayu, with a total of 35 participants, and involved several expert validators, including lecturers and teachers. The research results show that the validation of learning media reached a value of 96.36% (very valid), material validation 86% (very valid), test question validation 90% (very valid), and RPP validation 80.85% (valid). Hypothesis test analysis resulted in sig. (2-tailed) = 0.001, where 0.001 < 0.05, thus H0 is rejected and H1 is accepted. This indicates a significant effect of using website-based learning media with the Project Based Learning model on students' static routing competence. Based on the test results, it can be concluded that website-based learning media using the Project Based Learning model effectively improves students' static routing competence.
