Get PDFThis study aims to describe the readiness of science/chemistry teachers for the application of STEM learning (Science, Technology, Engineering, Mathematics) and to describe the supporting and inhibiting factors of science/chemistry teacher readiness for the application of STEM learning. This research is a descriptive research with a quantitative approach. The population of this study is the number of science/chemistry teachers who teach at SMA/SMK/MA Country in District Gerung. The sampling technique in this study used purposive sampling. The number of samples was 12 science/chemistry teachers in SMA/SMK/MA Country in District Gerung. Data collection techniques using interview guidelines and questionnaire techniques which have been declared valid and reliable. The results of the research on attitude readiness, emotional readiness, cognitive readiness and behavioral readiness in public SMA/SMK/MA Country in District showed an average gain of 74.04%. This means that the readiness of science/chemistry teachers towards the application of STEM learning is more likely to be ready. Based on this, it can be interpreted that some teachers have implemented STEM learning and have never implemented STEM learning, only to the extent that they are ready to do STEM learning. This readiness is also influenced by supporting factors such as: responsibility, enthusiasm, willingness to adapt, critical thinking, thinking contextually, aware of one's own worth and will, being able to integrate various scientific disciplines, carrying out partnership functions and being good at managing time. While the inhibiting factors are independence and awareness of strengths and weaknesses, this is because some teachers have never participated in STEM learning training and teachers have never tried to apply STEM education in science/chemistry learning. Furthermore, teachers find it difficult to improve their quality in preparation for implementing STEM learning and teachers are not yet proficient in preparing lesson plans that are appropriate to STEM learning.Penelitian ini bertujuan untuk mendiskiprisikan kesiapan guru IPA/kimia terhadap penerapan pembelajaran STEM (Science,Technology, Engineering, Mathematics) dan mendiskripsikan faktor pendukung dan penghambat kesiapan guru IPA/kimia terhadap penerapan pembelajaran STEM (Science,Technology, Engineering, Mathematics).

Effect of Different Feeding on The Growth Rate of Maggots (Hermetia illucens)
Get PDFPopulation growth and high consumption patterns have led to increased waste production. This encourages people to look for effective and economically valuable solutions. One potential action that can be taken is to convert organic waste into practical utilization as food for maggot (H. illucens). Maggot (H. illucens) is one of the decomposer organisms that has a fairly high nutritional content. The objective of this study was to evaluate the impact of various feed ingredients, including vegetable waste, rice husk and bran, on the growth rate of larvae (H. illucens). The study was conducted from October to November 2024 in Meurandeh, Langsa Lama, using experimental methodology with a Rancangan Acak Lengkap (RAL) with 6 treatments and 4 repetitions for 21 days. P1: 100% bran, P2: 100% vegetable waste, P3: 100% rice, P4: combination (50% bran + 50% vegetable waste), P5: combination (50% bran + 50% rice), P6: combination (50% bran + 25% vegetable waste + 25% rice. The results showed that treatment A produced the highest absolute biomass of maggots (H. illucens), with an average of 204.25 grams, while treatment B recorded the lowest absolute biomass of maggots (H. illucens), with an average of 157.25 grams. And the highest organic waste composition for maggot length growth (H. illucens) The average length recorded in treatment E was 3.88 cm, while treatment F showed the shortest average length. The Anova results show that different feeding has no significant effect (P>1.112) total weight of biomass maggot (H. illucens), this shows that one of the elements that influence maggot growth is the quality of feed that is rich in protein and normal water content so that it can allow maggot to receive nutrients optimally
