Motivasi adalah sesuatu yang dapat berpengaruh terhadap hasil belajar siswa. Motivasi dapat diperoleh dari dalam diri sendiri, maupun dari lingkungan. Dilakukannya penelitian ini dengan tujuan melihat hubungan motivasi terhadap hasil belajar siswa. Jenis penelitian yang digunakan dalam penelitian ini adalah penelitian kuantitatif. Populasi penelitian ini adalah siswa kelas V SD Inpres Muting 7 Distrik Muting Tahun ajaran 2018/2019 sebanyak 32 siswa. Pengambilan sampelnya menggunakan teknik sampel jenuh, di mana semua jumlah populasi dijadikan sebagai sampel. Teknik pengumpulan data yang digunakan dalam penelitian ini adalah angket (kuesioner). Data yang dikumpulkan, kemudian dianalisis secara kuantitatif. Hasil analisis data diperoleh nilai uji korelasi -0,08 yang berada pada interval koefisien sangat rendah sedangkan koefisien determinan 0,74. uji t test menunjukan nilai = 2,04. Hal ini menunjukan bahwa H0 ditolak yang berarti ada hubungan antara motivasi belajar dengan hasil belajar siswa kelas V SD Inpres Muting 7 Distrik Muting

This study aims to describe the application of the Discovery Learning learning model assisted by Powerpoint media to students of class X IPA 3 of SMA Negeri 2 Merauke in improving the results of physics learning. This type of research is PTK using a descriptive approach consisting of 2 cycles. Based on the results of this study, it can be concluded that discovery learning learning models make students able to become more active and motivated to find their own solutions to the problems faced. The use of powerpoint media that displays moving images also makes learning more interesting. This is evidenced by an increase in scores at the end of each cycle. To increase the enthusiasm of students, then at the end of the cycle an award is given in the form of congratulations to students or groups that excel.  Keywords: Media Powerpoint, Discovery Learning, Learning Outcomes

Salt hydrate CaCl2.6H2O is one of inorganic Phase Change Material (PCM) that have melting temperature (Tm) of about 29 °C and latent heat of fusion (DH) of around 190 kJ/kg that can be used for latent thermal energy storage. This material can be used for conditioning the air-temperature of the room, in order to reduce the electrical energy consumption for air conditioning (AC) system. In order to reduce the subcooling and phase separation effects of CaCl2.6H2O to maintain its performance, we adopt sonocrystallization technique that uses ultrasound radiation for crystallization of CaCl2.6H2O. The data are taken qualitatively for the crystal growth observation and quantitatively based on real-time temperature recording. The results show that sonocrystallization can slightly reduce the phase separation effect and improving the quality of the crystal. Hence, the resulted crystals have large and long size, uniform distribution and dense arrangement.

Conservation of nature or environmental is one of the alternatives in reducing the effects of global warming. Various ways are done so that the conservation of this nature can be realized. One of them is through the sasi culture, the culture of the people of eastern Indonesia, namely Maluku and Papua. Sasi culture is one of local wisdom that forbids humans to take or process natural products from a region within a certain period. The implementation of sasi is based on culture and also on religion. Sasi based on religious is called religious sasi. This research is descriptive research to explain the role of religious sasi culture as one way to preserve the environment. Data were collected by a literature study. The results show that culture sasi can preserve the environment. This is because, in the implementation of sasi, it is prohibited to take and manage the natural products within a certain period. During the duration of the sasi, plants or animals in the sited area are given the opportunity to grow and multiply without any disruption.
