Abstract

Lecturers apply various models or learning strategies to the students which causes different student responses in joining the teaching learning process. However, the student responses only focus on their cognitive. It means that the lecturers only assess on the students’ achievement. Whereas the applicat ion different models or learning strategies have a purpose to achieve positive responses from the students. It is happened in learning linear program subject. In addition, there are also student responses on the teaching materials application for linear program subject based on contextual approach. Furthermore, the objective of the research is to describe student responses on the application of linear program teaching materials using contextual approach through Linever.Linever means that an acronym for Lindo and Excel Solver software. Moreover, textbook and student’ worksheets (LKM) are the teaching materials which are developed. The technique of data collection uses student responses questionnaires. The result of the research is the student responses on the linear program materials using contextual approach through Linever got 96.6%. In conclusion, this research had achieved the positive responses from the students in learning linear program subject.

Abstract

Oyster mushroom farmer group REJOSARI MAKMUR and MANDIRI are two mushroom business groups in Meteseh village which was formed in response to the decline of the indigenous economy. They process mushrooms into chips sold in traditional markets. Their problems are low production capacity, low product diversification, oil content in chips is still high, and product packaging is not carried out properly. The objectives are (1) to develop business partners' mushroom so that they are able to become economically independent communities, (2) improve creative and innovative skills, use appropriate technology skills in draining, packaging, storage and product marketing skills. The method of achieving the goal is to increase production capacity through baglog enhancement, improve the skills and creativity of making various processed mushroom foods, applying oil slicing machines, and developing methods for packaging mushroom food products using packaging machines and labeling on product packaging. The results showed that the durability of chips for not sluggish and rancid increased from 4 days to 16 days. Mushroom entrepreneurs have been able to make various processed mushroom foods from 1  (chips)  into  several  products  including  nuged  and  mushroom  meatballs. Packaging becomes better, attractive and tight so that the flavor increases and food resistant.Keywords: Oyster mushroom, capacity, packaging, product diversification

Abstract

Crackers "Sarah" and "Barokah" have decreased cracker production due to, firstly, low speed of chopping because it is still done manually, and second is the failure of drying crackers as a result of the absence of the sun. The purpose of community service is to improve the quantity and quality of cracker production. The method applied is by implementing chopper machine and dryer dryer machine on dry cracker cracker. The results show that the use of chopper machine is able to remind the speed of chopping while improving the quality of the grain. The use of cracker dryer machine can accelerate drying so as to increase the production of crackers.Keywords: chopper machine, drying machine, crackers

Abstract

The problems in this research are (1) the expository method used in learning processes becauses lack of motivation and activeness in students, (2) the students' understanding of mathematical concepts are low. This research is an R&D type research that aims to develop and aplly a valid and effectivekotakkatik media. Kotak-katik media uses the contextual approach with ADDIE development method and the TGT cooperative learning model. The population in this research consists of 8th grade students in JHS of Muhammadiyah 1 Kudus. The samples are obtained using purposive sampling. 85.5% validity rate is obtained, meaning that this media is very valid. Effectivity analysis shows that complete individual understanding of the concepts reaches the value of87.2667 and classical completion reaches the proportion of 86.6667%.Motivation and activeness are ability in understanding the mathematicalconcepts with effect percentage of 89,9%.  Application of this kotak-katiklearning media creates difference in the measure of mathematical concept understanding, in the experimental class is 87,2667 better than control class is 79.1333. Based on those results, therefore the development of kotak-katik media through contextual approach to mathematical concept understanding of straight-sided solid shapes is valid, effective, and suitable to use as a new variation in learning.
