APLIKASI VEKTOR UNTUK ANALISIS PERGERAKAN GRUP SUNSPOT MATAHARI DARI DATA SUNSPOT SIKLUS KE-23

Grup sunspot (bintik matahari) di matahari mengalami evolusi yaitu pertama muncul dari sisi timur bergerak ke sisi barat. Perpindahan grup sunspot dapat diproyeksikan dalam koordinat bujur dan lintang matahari. Dalam suatu evolusi, perpindahan grup sunspot hari pertama sampai dengan hari ke n dapat diimplementasikan sebagai akumulasi dari n vektor ri. Dimana, vektor ri adalah menggambarkan jarak tempuh perjalanan grup sunspot pada hari ke i. Sehingga total vektor ri merupakan vektor resultan,R. Apabila vektor resultan R dibagi lama evolusi (= n hari) maka diperoleh vektor R = (+boB,+loL) Dimana, besaran b adalah rata-rata selisih derajat bujur/hari, dan l adalah dari rata-rata selisih derajat lintang/hari. Besaran l bernilai positif jika arah gerak grup sunspot menuju ke arah ekuator, dan sebaliknya l bernilai negatif jika grup sunspot menuju kutub matahari. Pergerakan sunspot (bintik matahari) di permukaan fotosfer merupakan implementasi adanya pergerakan materi plasma dari dalam matahari merambat keluar menuju fotosfer yang dipengaruhi oleh medan magnet di lapisan konvektif matahari. Data yang digunakan untuk menganalisis gerak grup sunspot adalah sampel grup sunspot kelas H dan J di belahan selatan cakram matahari hasil pengamatan matahari SPD Watukosek dari tahun 1997 - 2008 (siklus ke 23). Kata kunci : sunspot, lapisan konvektif, belahan selatan matahari

MODIFICATION OF ADSORBEN SILICA FROM RICE HUSK ASH WITH CHITOSAN TO ADSORPTION ION MANGANESE (TOTAL)

Adsorbent silica from rice husk ash supported by chitosan can be used to adsorb Mn (Total) metal. The adsorbent is regulated by adjusting the composition of 65% silica and 35% chitosan. The characteristics of the silica-chitosan adsorbent and the adsorbent interaction with Mn (Total) are believed to be based on Fourier Transform Infared (FTIR) data. The concentration of Mn (Total) ion after adsorption is determined by Atomic Absorption Spectrophotometer (AAS). The results showed optimum pH at pH 5 percentage adsorption 79.45% and optimum contact time at 60 minutes with adsorption percentage 96.78%, and obtained chitosan-silica adsorption capacity of Mn (Total) ions of 1.0349 mg/g

Promoting Student's Problem-Solving Skills through STEM Project-Based Learning in Earth Layer and Disasters Topic

Located in the Pacific Ring of Fire, Indonesia is endangered by natural disasters. Through the changing of learning activity in a proper way by the application of STEM Project-Based Learning, future generations are expected to develop the knowledge and thinking skill to solve the problem. Therefore, this study aimed to investigate implementing STEM Project-Based Learning on student's Problem-Solving Skills. This research used a Pre-Experiment method with a One-Group Pretest-Posttest design and essay questions as data collection tools. In this research, 30 7th-grade students at one school in Bandung, Indonesia, were chosen as the participants. The data analysis showed significant improvement between student's Problem-Solving skills pretest and post-test (N-Gain=0.73). In addition, Idea-Finding is the most significant improvement during the Fact-Finding on the lowest. Based on the result, STEM Project-Based Learning is recommended to improve students' Problem-Solving Skills since they can use their integrated knowledge to solve a real-world problem
