Abstract

This study aims to produce guided inquiry based learning modules on optical instrument material and test their effectiveness. This research and development refers to the modified Borg and Gall (1983) model. Techniques for collecting data through observation, questionnaires, tests and documentation. The results of the feasibility test showed that the physics learning module based on guided inquiry on optical instrument material was feasible to use with the percentage of the feasibility score from the material experts amounting to 87.27% and from media experts amounting to 91.67%. The effectiveness test results show that the module produced effectively. This is indicated by the results of t-test calculations on student learning outcomes test data obtained ttable 2.048 and tcount of 6.433, so tcountttable which means ????0 is rejected, ???????? is accepted.

Abstract

This RD research resulted in a four-tier diagnostic test instrument based on local wisdom. The purpose of the study was to describe the instrument's characteristics, test the validity, reliability, and characteristics of the items developed, and describe the misconception profile of the students of MA Islamiyyah Attanwir Talun. The development method uses the Borg Gall model with sample selection through purposive sampling. Data collection techniques include tests, interviews, questionnaires, and documentation. The test instrument was made by correlating physics material and the local wisdom of the community. The validity test results by the expert stated that the instrument developed was valid. The reliability of the developed instrument is 0.978. The test instrument consisted of 15 moderate and 13 difficult questions; with differentiating power, 12 items were corrected, seven were accepted but had to be corrected, and nine were accepted without improvement. There were 50% misconceptions about the answer, 57.14% about the reason, and 50% about the answer and reason. The highest misconception occurs in the concept of applying the moment of inertia, with a percentage of 67.23%. The lowest misconception is found in the concept of rigid body equilibrium, with a percentage of 38.98%.

Abstract

Tea is a beverage that contains caffeine, an infusion made by brewing leaves, leaf buds, or leaf stems. Kersen, also known as talok (Muntingia calabura), is a type of tree with small, sweet, bright red fruits. In addition to its edible fruits, the leaves can also be used as an ingredient for beverages. Kersen leaves have antiseptic and antibacterial properties, making them useful for boosting the immune system and treating various illnesses. For this reason, our team intends to provide assistance in producing tea from kersen leaves for the residents of RT 05 RW 05, Lamper Tengah Subdistrict, Semarang City. The stages of this community service program include: (1) Socialization of the benefits of kersen leaves; (2) Training; (3) Monitoring and mentoring.The impacts of this program include: (1) PKK women’s group members of RT 05 RW 05, Lamper Tengah Subdistrict gain knowledge about the benefits of kersen leaves; (2) Improved knowledge and skills in processing kersen leaves into tea bags; (3) Increased entrepreneurial motivation among PKK women’s group members of RT 05 RW 05.
