AbstrakPenelitian ini bertujuan untuk mengetahui kelayakan dan respon siswa terhadap modul berbasis discovery learning materi struktur dan fungsi jaringan tumbuhan. Metode yang digunakan Research and Development mengacu pada Borg & Gall yang dimodifikasi menjadi 7 tahapan meliputi penelitian dan pengumpulan data, perencanaan, pengembangan draft produk, uji coba lapangan awal, revisi hasil uji coba, uji coba lapangan dan revisi produk operasional. Sampel penelitian adalah siswa SMAN 4 Pontianak, MAN 2 Pontianak dan SMA Mujahidin, dengan uji coba lapangan awal berjumlah 9 orang, sedangkan uji coba lapangan utama berjumlah 36 orang. Hasil validasi modul dari setiap aspek kelayakan isi, kebahasaan, sajian, dan kegrafisan memperoleh nilai sebesar 1,00 dengan kriteria sangat valid. Hasil respon uji coba lapangan awal sebesar 81,73%, dan uji coba lapangan utama 82,16%. Dapat disimpulkan bahwa modul berbasis discovery learning layak digunakan sebagai bahan ajar pada materi struktur dan fungsi jaringan tumbuhan dan mendapatkan respon dengan kategori sangat kuat.Kata kunci: modul berbasis discovery learning, struktur dan fungsi jaringan tumbuhan, respon, kelayakan AbstractThe study aims to determine the feasibility and response of students to the module-based discovery learning structure material and plant tissue function. The methods used by research and Development refer to the Borg & Gall modified into 7 phases covering research and data collection, planning, product draft development, initial field trials, revision of trial results, field trials and operational product revisions. The research samples are the students of SMAN 4 Pontianak, MAN 2 Pontianak and Mujahidin High School, with an initial field trial of 9 people, while the main field trials amounted to 36 people. The result of module validation of every aspect of content eligibility, linguistic, servings, and graffiti obtained a value of 1.00 with very valid criteria. The results of the initial field trial response amounted to 81.73%, and the main field trial was 82.16%. It can be concluded that the discovery learning-based module deserves use as a teaching material on the structure material and plant tissue function and get a response with a very strong category.

The research subjects were 22 students of class VIII. The research method used classroom action research conducted in two cycles. Each cycle consists of four stages, namely planning, implementing actions, observing, and reflecting. The instruments used observation sheets of the learning process and learning activities, as well as learning achievement test questions. Data analysis techniques used descriptive statistics. The results showed that the learning process in the first cycle was 92.31% and the second cycle reached 100%. Learning activities of students in the first cycle was 77.27% and the second cycle was 90.91%. Learning outcomes show the number of students who completed in the first cycle was 18 people with a percentage of 81.82% and the second cycle was 21 people with a percentage of 95.45%.</em></p>
The study aims to document the medicinal plants and knowledge of the use of medicinal plants used by traditional healers in Bunut Village. This research was conducted in Bunut Village, Kapuas Subdistrict, Sanggau Regency, West Kalimantan. In this study, we found a total of 31 species of medicinal plants used by traditional healers and those included in the 25 plants family. The most common family is Zingiberaceae. Herbal habitus is the most common use (51,61%). The plant part is leaves (53%) used by traditional shamans from Bunut Village. The most widely used method of processing plants is boiling (64,87%). The way of use that is often used is by drink (53%). Usage rules that are commonly used are 2x1 (65,63%). Doses of using medicinal plants are 1-3 strands/part (45%) and 4-6 strands/part (45%).Keywords: Bunut Village, Medicinal Plants, Sanggau Regency, Traditional Healer, Traditional Knowledge.
Grafena merupakan nanomaterial yang memiliki konduktivitas tinggi, dapat disintesis dari limbah pelepah sawit dengan komponen dominan selulosa, hemiselulosa dan lignin yang dimanfaatkan sebagai sumber karbon. Penelitian ini bertujuan untuk mengetahui cara sintesis grafena dan karakteristik grafena yang dihasilkan dari limbah pelepah sawit. Metode sintesis grafena secara umum terdiri dari proses karbonisasi, sintesis grafit oksida, kemudian reduksi grafit oksida menjadi grafena. Karbonisasi pelepah sawit menggunakan suhu 300˚C selama 60 menit yang selanjutnya dilakukan pengayakan berukuran 270 mesh. Grafit oksida (GO) disintesis menggunakan metode Hummers yaitu reaksi oksidasi grafit menjadi grafit oksida dengan oksidator berupa KMnO4 dalam suasana asam (H2SO4) yang menghasilkan campuran berwarna coklat tua. Grafit oksida diperoleh sebagai bubuk. Selanjutnya, grafit oksida direduksi menjadi grafena dengan reduktor Zn dalam suasana asam (HCl). Hasil karakterisasi dilakukan dengan perbandingan literatur; hasil XRD menunjukkan hasil berbeda pada difraktogram grafit, grafit oksida dan grafena dengan tingkat kristalinitas yang berkurang. Hasil FTIR menunjukkan adanya gugus fungsional O-H, C=O, ikatan C–OH dan C–O hanya pada grafit dan grafit oksida. Hasil SEM menunjukkan grafena berbentuk lembaran yang lebih tipis dari grafit oksida. Sintesis grafena dari limbah pelepah sawit dapat dilakukan dengan menggunakan metode Reduksi Grafit Oksida (GO) dengan Reduktor Zn.
This paper describes the effect of flipped classroom strategy toward students' listening comprehension in IAIN Batusangkar. The design of this study was quasi experimental in which there are two classes that become experimental class and control class.The population of the research was the first semester students of English Department in IAIN Batusangkar. The data were collect from listening comprehension test, based on homogeneity and normality testing. It was found that the data is homogenous and normal. T-test was used in order to see the effect of flipped classroom strategy on students' listening comprehension. There are some studies was conducted related to the flipped classroom strategy. The result of data analyzing shows that there is significance result after the treatment. The students in experimental class got better listening comprehension than in the control class. In conclusion, flipped classroom strategy can be an option for lecturer to vary their teaching listening comprehension strategy. It can be said that this strategy is appropriate strategy for those students at first semester undergraduate students.
