Development of PISA-like Math Tasks in the Context of Musi Rawas District through Lesson Study System
No full textThis study aims to produce valid and practical PISA-like mathematics tasks in the context of Lake Aur and Pindang Musi Rawas and have a potential effect on students' ability to solve problems. This study used the design research method of the type of development studies with the preliminary stage and formative evaluation. In addition, in its implementation, problem development is also carried out through a lesson study system. The research subjects were class IX students of SMPIT Annida Lubuklinggau. Data was collected using walkthrough techniques, documentation, observation and questionnaire which were then analyzed using qualitative description methods to describe the results of each stage of development. This research produced sharing tasks in the context of Lake Aur and jumping tasks in the context of Pindang Patin Musi Rawas which are valid, practical as well as having a potential effect on students' mathematics ability to identify and solve PISA-like mathematics tasks. The results showed that the use of context and collaborative learning in solving PISA-like mathematics tasks made the questions easier to understand and the process more enjoyable. This is because the context of Lake Aur and Pindang Musi Rawas is known and close to students' daily lives and there is a process of teaching each other among fellow students
STATUS ANEMIA TIDAK BERHUBUNGAN DENGAN SUBTIPE DIFFUSE LARGE B-CELL LYMPHOMA
No full textAbstrakDiffuse large B-cell lymphoma (DLBCL) merupakan neoplasma sel-B sedang atau besar yang pola pertumbuhanya secara difus dengan inti besar. Sekitar 30-40 % kasus limfoma merupakan DLBCL. Berdasarkan fiturmolekuler dan cell of origin (COO), DLBCL dibagi menjadi subtipegerminal center B-cell (GCB) dan activated B-cell (ABC) / non-germinal center B-cell (non-GCB). Anemia menjadi salah satu kondisi klinis yang seringmenyertai limfoma. Anemia pada limfoma dikaitkan dengan prognostik yang lebihburuk. Tujuan penelitian ini untuk mengetahui hubungan subtipe molekular DLBCL dengan anemia. Penelitian ini adalah jenis penelitian cross-sectional, dengan sampel adalah semua pasien yang terdiagnosis DLBCL di RSUP Dr. Mohammad Hoesin Palembang tahun 2017-2021 sesuai kriteria yang ditentukan. Data Hb yang diambil adalah hasil pemeriksaan Hb paling awal pasien sebelum dilakukan biopsi. Dari 93 sampel, kasus DLBCL tinggi pada kelompokusia<60 tahun (64,5%), jenis kelaminlaki-laki (58,1%), lokasi ekstranodal (72%), varian sentroblastik (75,3%), dan subtipe non-GCB (75,3%). Anemia terjadi pada 76,3% kasus. Derajat mild (69%) memiliki proporsi yang paling tinggi. Tidak terdapat hubungan yang signifikan antara subtipe molekular DLBCL baik dengan status anemia (p= 0,97) maupun dengan derajat anemia (p= 0,97). Berdasarkan hasil penelitian, tidak terdapat hubungan yang bermakna subtipe molekular DLBCL dengan status anemia dan derajat anemia.Kata Kunci: DLBCL, SubtipeMolekular, GCB, Non-GCB, Anemia
Optimalisasi Respons Surface Terhadap Profil Asam Tempe Lotus (Nelumbo nucifera) Rawa Perikanan
Get PDFThis study aimed to determine the best using of combination processes in the manufacture of lotus tempeh and determine the dominant acid profile in lotus seeds tempeh. This study was conducted with 2 stages of research design, the first stage was optimization of the best process in the manufacture of fermented lotus (lotus tempeh) using the Response Surface Methodology (RSM) box Behnken with data analysis by Minitab software version 19. In the second stage, the optimal data of the first stage analyzed by descriptive analysis of acid profile and alcohol content. Based on the measurement of acid content in lotus seed tempeh ranged from 4.33-20.5% for the best combination treatments (0.5 g starter, 24 h soaking time, and 36 h fermentation time), and the alcohol content in optimal tempeh obtained from 4.74% to 5.06%. The optimal lotus tempeh has 46 compounds in acid profile as tempeh flavour, wherein cyclobutanol and ethanol as the dominant compound in the acid profile.

No full textThis research aims to determine students' difficulties in Genetics Course. The descriptive method was used in this study. The research sample was 85 Department of Biology Education students enrolled in the Genetics course. The instrument used was cognitive tests and questionnaires with content questions concerning students' learning difficulties. Cognitive test results showed an average value of 49.5, with a highest score of 90 and the lowest was 11. 52% of the students suggested the Genetics course is a tricky subject. The most crucial factor of learning difficulties is inappropriate learning style (66.3%), Genetics characteristics (65,8%), and lack of infrastructure (65.8%). The most challenging topics in genetics are linkage, crossing over, and chromosomes mapping (26.9%). This result is consistent with the questionnaire that 30% of the students stated that these topics are the most difficult in Genetics

Pengembangan Superkapasitor Bank dengan Kontroler ESP-32 Berbasis IoT sebagai Alat Penyimpan Energi
Get PDFThe purpose of this study is to develop an electrical energy storage device using a supercapacitor that is equipped with a dynamic voltage balancing system and an IoT-based controller that can send data on the condition of the bank supercapacitor to users via a wireless network. This research is a type of research and product development with a 4D development model. The process of design, manufacture, and testing is carried out in the laboratory using a dummy voltage source. The data processed in the study are the total voltage of the supercapacitor bank, the maximum voltage of each individual supercapacitor in the supercapacitor bank, the strength of the current supplied to the supercapacitor and the time required for the charging and emptying of the supercapacitor. The instruments used to create bank supercapacitors are capacitors, resistors, ESP-32 controllers, Zener diodes, and voltage sources. The research data was obtained using the Arduino IDE application and then plotted into a graph. Data processing will result in the performance of the bank supercapacitor which includes the total capacity of the supercapacitor, the maximum current that can be supplied, and the most ideal conditions for the charging and discharging of the supercapacitor bank. The result of this study is the development of a supercapacitor bank as an energy storage tool that has been equipped with a dynamic voltage balancing system and an IoT-based controller that can send data on the condition of the supercapacitor bank to users via a wireless network. This supercapacitor bank can be used instead of batteries that can be used as a voltage charger on electric bicycles, power banks, and non-battery electrical energy stores
