Teknologi Pembuatan Perahu Tradisional oleh Masyarakat di Sekitar Danau Tigi Kampung Puyai

Penelitian ini bertujuan untuk mengetahui jenis kayu dan teknik pembuatan serta pemeliharaan dan pola transfer pengetahuan dari proses pembuatan perahu. Metode penelitian yang digunakan yaitu metode deskriptif dengan teknik wawancara semistruktural dan observasi langsung di lapangan. Hasil penelitian menunjukkan bahwa terdapat 12 jenis kayu dari 7 famili yang digunakan oleh masyarakat Kampung Puyai sebagai bahan baku pembuatan perahu tradisional. Terdapat 3 (tiga) jenis kayu yang sering digunakan untuk badan perahu yaitu Digi (Nothofagus recurva Steenis), Epo (Eugeniaanomala), Danmoane (Toona sp.). Proses pembuatan perahu meliputi pembagian batang, pembentukan perahu, penghalusan, penyelesaian (finishing), penarikan perahu ke danau dan pengujian kelayakan perahu. Pemeliharaan dilakukan untuk mencegah terjadinya  kerusakan perahu antara lain: pembersihan setiap kali pemakaiaan, perbaikan secara menyeluruh, perlindungan terhadap perahu dari panas matahari. Pola transfer pengetahuan pembuatan perahu secara tradisional kepada generasi berikutnya dilakukan dengan cara mengajak para pemuda untuk ikut serta dalam proses pembuatan perahu.&nbsp

MISKONSEPSI DALAM PELAJARAN MATEMATIKA MATERI FPB DAN KPK PADA SISWA KELAS IV SEKOLAH DASAR

This study on the background of some students is misconception of FPB and KPK materials. It is even more complicated if conception on a student is not treated immediately, and it will also affect the spirit or motivation of the student in learning. This study is intended to identify the causes of misconception that students experience in resolving FPB and KPK issues. The subject was an iv student at SDN karawaci Baru 1 city tangerang. This study is conducted using test methods, as well as interviews. After having valid data and identifying the source of misconception, this study was carried on by interviewing the homeroom teacher of the results, it shows that there are conceptual concepts, systemic misconception, and misconception calculations. Misconception occurs because of miscalculation, that is, when answering FPB and KPK outcomes or determining outcomes. The causes of misconception are students and their teaching methods. To enhance students' understanding of FPB and pef, then they can use more interactive and practical learning method

Stair-Hexagonal Slot Antenna with Coplanar Waveguide Technique for Biomedical Applications

Breast cancer is the most common disease suffered by women and increases significantly. Ultra-Wideband (UWB) is a technology that applies electromagnetic signals with wide bandwidth that are currently widely used in the medical field. This research introduces the design of the Stair-Hexagonal slot antenna with the Coplanar Waveguide (CPW) technique which operated at desired frequency of 5.8 GHz. Firstly, the design process of the antenna is adding stair slot to get wide bandwidth. Secondly by adding Hexagonal slot to get the best S11 parameter at the desired frequency. The purpose of antenna is to detect an object in body organs such as tumors and cancer. The antenna is printed and tested. The measured return loss shows that the antenna works well in the desired frequency with wider bandwidth than simulated one. The measured bandwidth of 7.88 GHz is achieved. The gain of the antenna from the simulation is 2.42 dBi and radiation pattern of simulation and measurement are bidirectional, wherein the highest gain is in the rear position. Further analysis is done by comparing the proposed antenna with the existing related works. The result of this research shows the practical usage of the flexible substrate because it can increase the accuracy of object detection

Hydropriming Improves Germination and Plant Recovery During Embryo Rescue of Wild Banana Musa acuminata var. tomentosa

Wild bananas are believed to have genes for resistance to biotic and abiotic stress in nature, making them potential genetic resources for creating superior varieties. Wild banana seeds, such as Musa acuminata var. tomentosa are generally difficult to germinate in vivo, so that in vitro embryo culture technique is needed. This study aimed to increase embryo germination and regeneration of wild banana M. acuminata var. tomentosa by soaking the seeds as hydropriming. The treatment comprised of soaking the seeds in sterile distilled water for four periods of time: 0 (control), 1, 4, and 7 days. A total of 45 embryos for each treatment were planted on petri dishes containing MS + 0.5 mg/L BA + 1 mg/L biotin + 1 mg/L proline. The results showed that hydropriming increased the rate of embryo germination and regeneration. Seeds soaked for 1, 4, and 7 days successfully resulted in embryo germination percentages of 87%, 62%, and 62%, respectively, while the control unsoaked seeds germinated with a lower percentage of 42%. One-day soaking treatment was the most optimal treatment to increase the rate of germination and regeneration as well as obtained the best vigor as demonstrated by the highest average height of plantlets, number of leaves, and roots than other treatments. Thus, 1-day seed hydropriming is the best treatment for embryo rescue and regeneration of wild banana M. acuminata var. tomentos
