Media Pembelajaran Pengenalan Alat Transportasi, Musik, dan Benda di Sekolah bagi Siswa Tunarungu Sekolah Dasar

A remarkable school – B (SLB) YRTRW Surakarta is a spesial school for children with special school for children with special needs to help provide education. According to a survey of SLB-B YRTRW Surakarta, it is difficult for students to get the names of objects right anf there are still mistakes, and it is also difficult for students to play because the learing methods are less interesting and therefore not focus on the material presented by teachers. An alternative or solution is to provide the learning media in the form of applications. The appication is called BELMA (together learning) abaout the introduction of transportation tools, Musical Instruments, and objects in the school environment for fourth-grade elementary school students. The founding of the media of education is a method for observation, analysis or problem identification,  and interviews. The result of research based on questionnaires are 87.871%, and this application can thus help the learning process. The purpose of this study is to be expected to help both tearchers and students in the learning process in class so that students can be quick to understand and enthusiastic about material delivery.Sekolah Luar Biasa-B (SLB) YRTRW Surakarta merupakan sekolah bagi anak-anak yang berkebutuhan khusus untuk membantu memberikan pendidikan awal. Berdasarkan survei terhadap SLB-B YRTRW Surakarta yaitu siswa masih sulit untuk menjabarkan nama benda dengan benar dan masih ada kekeliruan, selain itu siswa cenderung bermain dikarenakan metode pembelajaran kurang menarik sehingga tidak fokus terhadap materi yang disampaikan oleh guru. Alternatif atau solusinya yaitu dengan memberikan media pembelajaran dalam bentuk aplikasi. Aplikasi ini bernama BELMA (Belajar Bersama) mengenai pengenalan alat transportasi, alat musik, dan benda di lingkungan sekolah bagi siswa kelas empat sekolah dasar. Perancangan media pembelajaran edukasi menggunakan metode dengan melakukan observasi, analisis atau idenifikasi masalah, dan wawancara. Hasi penelitian berdasarkan kuesioner adalah 87,871%, dengan demikian aplikasi ini dapat membantu proses belajar.

Penerapan Pembelajaran Kooperatif Tipe Student Team Achievement Division (Stad) Untuk Meningkatkan Hasil Belajar Matematika Siswa Kelas III SD Negeri 25 Bagan Melibur

This research was based on the mathematics learning outcomes of students at class III SDN 25 Bagan Melibur. There were only 13 of 24 students (54,17%) who achieve the Mastery Minimum Criteria on topic about using the measuring tool in problem solving and the learning process is still teacher centered. This research is action research which aims to increase the mathematics learning outcomes of students at class III SDN 25 Bagan Melibur through the implentation of cooperative learning in type student team achievement division (STAD). The subject is 24 students at class III SDN 25 Bagan Melibur which consist of 10 boys and 14 girls with the heterogenous ability level. The instruments of data collection were observation sheets and test of mathematic learning outcomes. The observation sheets were analyzed in qualitative desciptive, while the test of mathematic learning outcomes was analyzed in quantitative descriptive. The qualitative descriptive showed that there is an improvement of the previous learning process to the first and second cycle. The result showed an increasing number of students who achieve the Mastery Minimum Criteria from the basic score with the percentage 54,17% to 75% on the first daily test and 83,33% on the second daily test.

Potensi Ekstrak Kapang Endofit Asal Rimpang Kunyit Sebagai Antimalaria Dan Antioksidan

Malaria infection is still a public health problem, especially in developing countries, including Indonesia. Malaria infection is usually accompanied by increased free radicals in the body of the patient. This situation will cause decreasing the immune system of the patient. Explorating of new drugs that have antimalarial and also antioxidant activity is very important. Therefore, this study aims to determine in vitro antimalarial and antioxidant activity of endophytic fungi extract origin turmeric from Sukabumi. This study begins with fermentation process of endophytic fungi on the broth medium and ethyl acetate was used to extract the filtrat to gain the test extracts. Heme polymerization inhibition and free radical DPPH scavenging method were used to antimalarial and antioxidant in vitro assay respectively. The results showed that 18 isolates of endophytic fungi have antimalarial activity and one isolate inactive and also all isolates have antioxidant activity. Smi.Cl.6F isolate was the most active isolate on the antimalarial and antioxidant assay with IC50 value of each assay were 1.93 mg/mL and 32.28 mg/L respectively. Therefore, Smi.Cl.6F isolates potentially be used as new antimalarial drugs
