Effects of the Jigsaw and Teams Game Tournament (TGT) Cooperative Learning on the Learning Motivation and Mathematical Skills of Junior High School Students

This study aims to: 1) describe the effectiveness of the jigsaw and TGT cooperative learning in the learning motivation and mathematical skills of junior high school (JHS) students, and 2) investigate the significant difference in the learning motivation and mathematical skills between the JHS students learning through the jigsaw cooperative learning and those learning through the TGT cooperative learning. This study was a quasi-experimental study using the non-equivalent pretest and posttest group design. This study involved two experimental classes. The research population comprised Year VII students of SMP Pembangunan Piyungan and the research sample consisted of two classes selected from all Year VII groups, with Year VII.A receiving a treatment of the jigsaw cooperative learning and Year VII.B receiving a treatment of the TGT cooperative learning. The instruments consisted of a test, i.e. a mathematical skill test, and a non-test, i.e. a questionnaire of mathematics learning motivation. To investigate the effectiveness of the jigsaw and TGT cooperative learning in the learning motivation and mathematical skills of JHS students, the data were analyzed using the one sample test. To investigate the significant difference in the learning motivation and mathematical skills between the students learning through the jigsaw cooperative learning and those learning through the TGT cooperative learning, the data were analyzed using the T2 Hotelling. To compare the effectiveness of the jigsaw and TGT cooperative learning in the learning motivation and mathematical skills of the students, the data were analyzed using the t-test. The normality was tested using the univariate approach, namely the Kolmogorov Smirnov, the homogeneity using the Box' M test, and the equivalence of the variance-covariance matrix using the Levene's test. The results of the study show that: 1) the jigsaw cooperative learning is effective for the JHS students’ mathematical skills and mathematics learning motivation; 2) the TGT cooperative learning is effective for the JHS students’ mathematical skills and mathematics learning motivation; 3) there is a difference in the effectiveness of the jigsaw and TGT cooperative learning in the JHS students’ mathematical skills and mathematics learning motivation; 4) the jigsaw cooperative learning method is more effective than the TGT cooperative learning method for the JHS students’ mathematics learning motivation; and 5) the jigsaw cooperative learning method is more effective than the TGT cooperative learning method for the JHS students’ mathematical skills.

Designing a Virtual Laboratory Using Android-Based Virtual Reality (Case Study: Laboratory of Basic Measurement and Electrical Engineering Instrumentation)

The existence of a laboratory in an engineering department is very important. The reality is that not all students can use existing laboratories in the engineering department due to limited laboratory space, tools and time constraints. The very rapid development of technology cannot be avoided. Active smartphone users in Indonesia reach over 100 million users. This proves that today's technological developments are very influential in everyday life. There are various kinds of technological developments that have occurred to date. One of these very rapid developments has led to digital technology which is increasingly favored by the community such as VR ( Virtual Reality ) technology which is able to provide the worldvirtual. Therefore, VR technology is used to solve student’s problems in accessing the laboratory. Where the VR technology takes a laboratory background. The utilization is in the form of virtual laboratory applications as digital educational media using VR technology which can later interact directly with practicum tools in the virtual laboratory application

Analisis Pengetahuan dengan Kemampuan Keluarga Merawat Pasien Dalam Mengontrol Halusinasi Dirumah

For the patient's hallucinations to be interrupted, family support is needed, where family support is one of the interventions that can be done to increase patient compliance in treatment; of course, family support can be done if the family knows how to treat sick family members. This study aims to identify knowledge of families' ability to care for patients with hallucinatory problems. The research design used in this study is an analytical survey with a cross-sectional approach. The population is a family of 78 patients, with a total sample of 47 respondents taken by consecutive sampling. Data were processed using Fisher's Exact Test statistical test. The results obtained a test value between knowledge and family motivation p = 0.000, showing the p-value < α (0.05). It was concluded that there is a relationship between knowledge and the ability of families to care for patients to control hallucinations at home. So that families are expected to be able to apply the knowledge and information obtained at the hospital related to procedures for caring for family members who experience hallucinations and try to find information related to hallucinatory diseases and immediately seek help if there is no relapseAgar halusinasi pasien dapat terputus, maka diperlukan dukungan keluarga, dimana dukungan keluarga merupakan salah satu intervensi yang dapat dilakukan dalam meningkatkan kepatuhan penderita dalam melakukan pengobatan tentunya dukungan keluarga dapat dilakukan jika keluarga mengetahui cara melakukan perawatan pada anggota keluarganya yang sakit. Penelitian ini bertujuan mengidentifikasi pengetahuan dengan kemampuan keluarga merawat pasien dengan masalah halusinasi. Desain penelitian yang digunakan dalam penelitian ini adalah survey analitik dengan pendekatan cross sectional. Populasi merupakan keluarga pasien sebanyak 78 orang, dengan jumlah sampel sebanyak 47 responden yang diambil secara consecutive sampling. Data diolah menggunakan uji statistik Fisher's Exact Test. Hasil penelitian diperoleh nilai uji antara pengetahuan dengan motivasi keluarga p= 0,000 menunjukan bahwa nilai p < α (0,05). Disimpulkan bahwa terdapat hubungan pengetahuan dengan kemampuan keluarga merawat pasien dalam mengontrol halusinasi dirumah. Sehingga keluarga diharapkan mampu menerapkan pengetahuan dan informasi yang diperoleh di rumah sakit terkait dengan tatacara merawat anggota keluaganya yang mengalami halusinasi dan berusaha mencari informasi terkait penyakit halusinasi dan segera mencari pertolongan ketidak terjadi relap
