Abstract

Production the Gracilaria. gigas Harv. is cultivation is influenced by cultivation methods and net systems used as well as environment factor. This research aim to know the growth and production of the Gracilaria gigas using different cultivation methods and net systems and also to determimine the different cultivation method and net system which result in the highest growth and G. gigas production in Selok Adipala ocean in Cilacap. This research used an experimental method with Splitplot Design in 3 times replication for each treatment combination. Research result indicate that the different of cultivation methods and net systems yield different seaweed growth and production. The highest growth was yielded from G. gigas use the modification of floathing method with double nets system that is equal to 4.25,00 g/day. G. gigas using the floathing method with apit net system yield that was equal to 1.610,00 g/ m2 of cultivation sea weed on Selok Adipala ocean in Cilacap Keywords: cultivation methods and net systems, Gracilaria gigas, Selok Adipala ocean in Cilacap

Abstract

Penelitian ini bertujuan untuk melakukan penapisan profil senyawa, uji aktivitas sitotoksik, dan induksi apotosis dari ekstrak batang brotowali (Tinospora crispa L.). Ekstraksi dilakukan dengan maserasi menggunakan etanol 96% kemudian di fraksinasi dengan n-heksan, kloroform, etilasetat berdasarkan tingkat polaritas. Uji dilanjutkan kromatografi lapis tipis menggunakan fase diam silika gel GF 254 dan fase gerak campuran. Spot yang ada dilihat dibawah UV 254 nm dan 366 nm serta disemprot dengan reagen penampak noda. Ekstrak dan fraksi kemudian diuji aktivitas sitotosiknya dengan metode MTT, serta induksi apoptosis dengan metode double staining dan flowcytometri. Hasil penelitian menunjukkan bahwa ekstrak etanolik batang brotowali mengandung senyawa flavanoid, fenolik, dan terpenoid. Ekstrak mempunyai efek sitotoksik dengan IC50 sebesar 314 µg/ml dan fraksi F3 sebagai fraksi aktif mempunyai efek sitotoksik dengan IC50 sebesar 146 µg/ml. Pada konsentrasi 25 µg/ml, fraksi mampu menginduksi apoptosis sebesar 28,9 %, kontrol sel 17,90% dan doksorubisin 63,12%. Pemacuan apoptosis ditunjukkan dengan adanya warna orange dan terjadinya banyak badan apoptosis pada sel WiDr dengan perlakuan ekstrak yang lebih banyak dibandingkan dengan kontrol sel.

Abstract

The purpose of this research is to develop an inquiry-based Science-Physics Practicum Module on Vibration and Waves material to improve students' science process skills. The design in this study uses the Borg Gall development model which is modified into six research stages, namely: 1) potential and problems 2) data and information collection 3) product design 4) Design validation 5) Design revision 6) Product trial. This research was conducted at MTs Al-Jihad Pontianak. The subjects in this study were the subject of development (Validator) and the subject of product testing (students) for class VIII A, amounting to 17 students. Based on the results of data analysis, it can be seen that 1) Inquiry-based Science-Physics practicum module based on material expert assessment with an average score of 73% with appropriate criteria and based on media expert assessment with an average score of 75% with appropriate criteria, 2) Student responses to Inquiry-based Science-Physics practicum module with an average score of 79% with criteria strongly agree, 3) The value of students' science process skills after using the Inquiry-based Science-Physics practicum module increased from each aspect. The aspect of observing with an average score of 92% with very good criteria, aspects of predicting with an average score of 70% with good criteria, aspects of clarifying with an average score of 76% with very good criteria, aspects of communicating with an average score of 77% with very good criteria, measuring aspects with an average score of 94% with very good criteria.

Abstract

Education is one of the important pillars in nation development. The quality of education is largely determined by the quality of teachers. Quality teachers are able to create an effective and enjoyable learning process for students. One of the factors that supports the quality of learning is the use of interesting and interactive learning media. Scramble learning media is an interesting and interactive learning media. This socialization aims to provide knowledge and skills to SD Negeri 1 Kualasimpang teachers in creating interesting and interactive Scramble learning media. The results of the activity showed that the teachers were very enthusiastic in participating in the socialization and gaining new knowledge and skills in creating Scramble learning media. It is hoped that with this activity, SD Negeri 1 Kualasimpang teachers can apply Scramble learning media in the classroom learning process, so that they can improve the quality of learning and student motivation.

Abstract

The background of this classroom action research is the importance of learning application that is fun and more significance in conveying a concept on mathematics learning activities at 1st grade of SD Negeri 1 Kualasimpang and a lack of students’ understanding on the sum of story form, so that the results are less than the maximum. Based on those problems, through this research is expected to provide solution. The solution is to apply the method of learning to play role that can make students more active in the learning process and can improve the students’ learning result. This research uses classroom action research (CAR). This research is implemented by the class teacher with three stages, they are: planning, implementation, and reflection. Implementation of the act is done in a collaborative and participatory, in order to improve the performance and management of the classroom. The data collection techniques for this research are observation and testing technique, while the data analysis technique uses quantitative descriptive analysis technique.

Abstract

The learning motivation of grade 2 students at SD Negeri 1 Kualasimpang is still relatively low. This is shown by the lack of enthusiasm of students in participating in learning. This research aims to determine the effect of the Scramble learning model on the learning motivation of grade 2 students at SD Negeri 1 Kualasimpang. This research uses a quasi-experimental research design with a pre-test and post-test design approach. The research sample was 25 grade 2 students at SD Negeri 1 Kualasimpang. The research instrument used was a student learning motivation questionnaire sheet. The results of the research show that there is a significant influence between the Scramble learning model on the learning motivation of grade 2 students at SD Negeri 1 Kualasimpang. This is proven by the sig (2-tailed) value of 0.000 < 0.05. This research concludes that the Scramble learning model can increase the learning motivation of grade 2 elementary school students. The Scramble learning model can be an alternative learning model that can be applied by teachers to increase student learning motivation.

Abstract

In essence, elementary school phase A is a place where children play while studying or learn while playing. Therefore, every lesson must be fun and appropriate to the child's growth and development stage. One way that teachers can do this is by using ICT-based number tree media. The benefit of number tree media is that it sharpens children's brains, here it can be seen when children arrange numbers according to their sequence, training eye and hand coordination. Along with developments in the times and future education, the use of ICT must start from early childhood. Mastery of ICT should also be the basic essence of filling a life that is growing and developing. For this reason, phase A elementary school teachers should adhere to the principles of early childhood education in designing teaching development programs that involve ICT. In this service activity, the problem is the low understanding of teachers at SD Negeri 1 Kualasimpang regarding the use of ICT-based learning media. The solution provided by the service team is the socialization of the use of ICT-based number tree learning media. The result of this service is that there is an increase in knowledge for teachers regarding the use of ICT-based number tree learning media.
