Abstract

In the 21st century, science literacy is the main competence and indicator to achieve better and more sustainable future. However, limited facilities and resources raise as an issue that have implications to the less optimal application of science literacy empowerment in various regions, including in several areas in East Nusa Tenggara. The objective of this community service is to do mentoring program on the empowerment of science literacy for students at emergency schools in NTT. The target is school-age children living in the island who are subjected to illiteracy due to lack of supporting educational facilities. Methods implemented were through these four stages: (1) initial observation of the area, (2) mapping the problem, (3) socializing the programs, and (4) organizing the science literacy movement. The activities carried out were making educational learning media utilizing plastic waste, creating a reading corner equipped with some interesting books as additional references for children and parents to know about the outside world, creating educational games and actions for the natural surroundings. The results of the observation confirm that the community service program run effectively. It is indicated that the community service project is able to foster students’ interest in reading, writing, and arithmetic. This community service activity is expected to take part in the eradicating illiteracy rate and reducing number of productive age dropouts in East Nusa Tenggara Province.

Abstract

Abstrak Faloak  merupakan tanaman yang tumbuh di lahan kritis. Sebagai upaya mendukung pemuliaan dan konservasi tanaman faloak diperlukan informasi keragaman genetiknya. Salah satu metode analisis keragaman genetik adalah menggunakan penanda DNA yang berbasis PCR. Untuk itu diperlukan kondisi PCR (Polymerase Chain Reaction) yang tepat sehingga diperoleh hasil yang dapat dianalisis lebih lanjut. Penelitian ini bertujuan menentukan kondisi optimum PCR-RAPD (Polymerase Chain Reaction-Random Amplified Polymorphic DNA) tanaman faloak. Ekstraksi DNA dilakukan dengan metode CTAB. Optimasi dilakukan dengan menggunakan beberapa konsentrasi DNA cetakan dan MgCl2. Kondisi optimum PCR-RAPD tanaman faloak yang menghasilkan pita produk PCR yang jelas diperoleh  menggunakan 50 ng/ul DNA, 3 mM MgCl2 serta jumlah siklus termal 45 x. Kata kunci : PCR-RAPD, optimasi, tanaman faloak Abstract Faloak is a plant that grows on critical lands. In an effort to support breeding and conservation of faloak, information about its genetic diversity is required. One of the methods of genetic diversity analysis is using PCR-based DNA markers. For that purpose, proper PCR conditions is needed in order to obtain results that can be further analyzed. This study aimed to determine the optimum conditions for PCR-RAPD of faloak plants. DNA extraction was conducted using CTAB. Optimization was done by using several concentrations of DNA templates and MgCl2. The optimum conditions of PCR-RAPD of faloak plants that produce clear band of PCR products were obtained using 50 ng/ ul DNA, 3 mM MgCl2 and 45x thermal cycles Keywords : PCR-RAPD, optimization, faloak plant

Abstract

This study aims to discover the implementation of CTL and authentic assessment to the science learning outcomes on 4th-grade students of primary school in Kota Kupang. This study is quasi-experimental using a 2 x 2 factorial design. There are 110 students as the population, in which 60 students are appointed as the samples thru a random sampling technique. Data collection uses an objective test method. The data are analyzed using one-way ANOVA and two-way ANOVA that is followed by t-Scheffe test. The results of this study indicate that: (1) there is a difference of learning outcomes between the students who attend the CTL with the conventional learning, (2) there is a difference on the students’ learning outcomes who attend the performance assessment with the project assessment, (3) there is an influence of interaction between the learning model and assessment used to the learning outcomes, (4) there is  difference of the students’ learning outcomes who attend the CTL, in which it is between the students who attend the performance assessment and the students who attend the project assessment, (5) there is a difference of learning outcomes on the students who attend the conventional learning, in which it is between the students who attend the performance assessment and the students who attend the project assessment, (6) there is a difference of learning outcomes on the students who attend the performance assessment, in which it is between the students who attend the CTL and conventional learning, and (7) there is a difference of learning outcomes on the students who attend the project assessment, in which it is between the students who attend the CTL and the students who attend the conventional learning. Hence, the implementation of CTL and authentic assessments toward the science learning outcomes of 4th-grade students of primary school in Kota Kupang.

Abstract

The policy of adapting new habits during the COVID-19 pandemic in yellow and green zone schools became the basis for blended learning practices at SDIT AlFatih Cigombong, which became a pilot school in the Bogor Regency area. This study aims to analyze the effectiveness of blended-based classroom management at SDIT Al-Fatih. This study uses a qualitative approach with a qualitative descriptive method. The data were collected through interview, observation, documentation, and literature study. The data analysis method used descriptive analysis techniques. Research findings show that blended-based classroom management at SDIT Al-Fatih during the COVID19 pandemic was declared quite effective. It indicated from some aspects: teacher’s ability to manage learning, utilize learning media optimally, positive response of students to learning activities, learning objectives can be achieved, quantity of student assignments, giving fair rewards and grades to students, periodic assessments, classical minimum completeness criteria (KKM) achievement, actively involving students, attracting students’ interest and attention, active communication between teachers and parents regarding information related to student and school learning, having facilities and infrastructure to support the teaching and learning process. Furthermore, implementing blended-based learning considered effective in maximizing learning activities during the Covid-19 pandemic.
