Siswa merasa kesulitan dalam memahami konsep matematika, di mana pemahaman konsep matematika. Hal ini disebabkan karena model pembelajaran yang didominasi oleh guru sehingga siswa terbiasa mendapatkan informasi atau pengetahuan terkait materi pelajaran tanpa melalui proses menemukan informasi. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan model pembelajaran project based learning (PJBL) terhadap hasil belajar siswa.. Penelitian ini merupakan penelitian kuantitatif dengan pengambilan data menggunakan desain eksperimen. Populasi pada penelitian ini adalah siswa kelas VI Sekolah Dasar. Teknik pengumpulan data menggunakan pre test, post test, dokumentasi. Teknik analisis data menggunakan  perbedaan nilai antara Post-test dikelas eksperimen dan kelas kontrol. Hasil penelitian diperoleh nilai terendah pada kelas pres test yaitu 40, sedangkan nilai tertingginya yaitu 83.3. Berdasarkan perhitungan yang telah dilakukan diperoleh nilai rata- rata dari kelas pres test yaitu 70. Nilai terendah pada kelas pres test yaitu 60, sedangkan nilai tertingginya yaitu 100. Berdasarkan perhitungan yang telah dilakukan diperoleh nilai rata-rata dari kelas pres test yaitu 83.3. Model pembelajaran project based learning berpengaruh positif terhadap hasil belajar matematika. Implikasi penelitian ini diharapkan dengan menerapkan model PJBL ini hasil belajar siswa meningkat, dan siswa lebih mudah memahami konsep matematika dalam proses pembelajaran.

Fish drying by using additional salt as a preservative and adding flavor to the fish. This study aims to determine the effect of various doses of salt on the quality of tilapia, motan, dried salted lemongrass and the difference that does not use salt on the quality of fish. This type of research is quantitative research with experimental methods. The independent variable in this study was the concentration of NaCl salt as a treatment, namely 10%, 20%, 30% of the total fish weight. The controlled variables of this study were the type of fish, weather conditions, and materials used. The research process begins with weeding motan, tilapia, and lemongrass fish, namely motan fish, tilapia, and lemongrass fish, weighing 100 grams. Then the fish are weeded with running water, removed all the contents of the fish's stomach, and drained until the fish does not contain too much water. Then the addition of salt to the motan fish, tilapia, and lemongrass fish has been given, namely, 27%, 34%, and 41%. The duration of soaking or salting is 24 hours. After the salting time has been completed, the fish drying process is continued. The fish dried at a temperature of 30C to 35C for 2 to 3 days to obtain the desired characteristics of salted fish. Data was collected by testing the salt content in fish with different concentrations. The results showed a difference between salted fish and unsalted fish. Salted fish has a harder texture, taste better, and have a longer shelf life.

In the 2013 curriculum learning inelementary schools has implemented integrated thematic learning.meaning that the learning material presented is an integration and various subjects are packaged in an integrated manner using themes and sub-themes as unifying learning. Learning media thematic is a bridge between learning materials that must be adjusted to the needs of the characteristics of elementary school students who still think concretely and combine various concepts in one study into the themes contained in the media. Information and communication technology is a medium for carrying out activities such as processing, managing, and, transferring information with the principle of using ICT effectively, efficiently, attracting and stimulating creativity. ICT is one of the learning media that is widely usedin various fields of education because it increases effectiveness andefficiency in the learning process.

So far, most of the social studies education learning process at the school level is still conventional. It is undeniable that nowadays, many symptoms and social problems continue to be turbulent and disturb the life of society, nation, and state. The current state of social studies learning, especially at the elementary level, indicates neglect of local culture, which functions to build student character. It is due to the low exemplary and moral values of a student. This study aims to This study aims to analyze the values of exemplary social studies learning in elementary schools. This type of research is qualitative approach research chosen in this study to answer the questions. Data collection in this study is by interview and documentation. The method used in this study is a method with qualitative data collection. The data analysis technique used qualitative analysis. The results showed that exemplary values in social studies learning affected elementary school students. The implications of this research are expected to be able to instill exemplary values in social studies learning in elementary schools.
