The development of instructional especially media of a herbarium book is an innovation that aims to assist students in searching directly the object of leaf morphology studies. This development research starts from the needs analysis stage which is used to gather information, planning in media making, media design, media making, after that product validation by a team of media experts and material experts, then testing individual products, small groups and large groups. The subject of this product testing were students of the Biology Education Study Program at Pasir Pengaraian University. The results of the validation by the material experts showed that the quality of learning media using the herbarium book on leaf morphology material was included in the "very feasible" criteria, with an average score of 86.46%. The results of validation by media experts are included in the "very feasible" criteria, with an average score of 88.54%. Individual assessment obtained the criteria of "very feasible", with an average score of 84.16%. Judgement from small groups obtained a percentage of eligibility of 81.45% with very feasible criteria, and judgement from large groups of 83.95% with "very feasible" criteria. The results of the development of herbarium book media are very decent.

Salah satu cara membuat pembelajaran di kelas menjadi aktif dan menyenangkan adalah dengan menerapkan model pembelajaran cooperative. Dengan menerapkan Model pembelajaran cooperative picture and picture dapat meningkatkan pemahaman siswa terhadap materi yang dipelajari. Tujuan penelitian ini adalah untuk mengetahui pengaruh model pembelajaran picture and picture terhadap hasil belajar siswa kelas VIII SMP Muhammadiyah Rambah. Jenis penelitian ini adalah Quasi exsperiment. Rancangan yang digunakan adalah nonequivalent groups pretest-posttest. Populasi dalam penelitian adalah seluruh peserta didik kelas VIII yang berjumlah 57 orang. Sampel dalam penelitian ini adalah peserta didik kelas VIII-1 sebagai kelas eksperimen dan VIII-2 sebagai kelas kontrol. Teknik pengambilan sampel secara non random sampling. Teknik pengumpulan data tes soal objektif. Teknik analisis data hasil belajar menggunakan uji t. Sebagai persyaratan analisis digunakan uji normalitas dan uji homogenitas. Dari uji t didapat nilai thitung = 14,143 dan nilai ttabel= 1,703. Karena thitung > ttabel, maka hipotesis nihil (H0) ditolak. Kesimpulannya adalah terdapat pengaruh yang signifikan model cooperative learning terhadap hasil belajar Ilmu Pengetahuan Alam Materi Sistem Pencernaan

Penelitian ini bertujuan untuk menguji aktivitas antioksidan (E)-1-(4-klorofenil)-3-p-tolilprop-2-en-1-on (C1) dan (E)-1-(4-klorofenil)-3-(4-isopropilfenil)prop-2-en-1-on (C2). Penelitian ini bermanfaat sebagai langkah awal dalam pencarian alternatif senyawa antioksidan dan antibiotik baru dari senyawa kalkon. Pengujian bioaktivitas antioksidan dilakukan dengan metode DPPH. DPPH merupakan metode yang cepat, sederhana, dan tidak membutuhkan biaya tinggi dalam menentukan kemampuan antioksidan menggunakan radikal bebas 2,2-diphenyl-1-picrylhydrazil (DPPH). Metode ini sering digunakan untuk menguji senyawa yang berperan sebagai free radical scavengers atau donor hidrogen dan mengevaluasi aktivitas antioksidannya, serta mengkuantifikasi jumlah kompleks radikal-antioksidan yang terbentuk. Bioaktivitas antioksidan senyawa kalkon (E)-1-(4-klorofenil)-3-p-tolilprop-2-en-1-on memiliki nilai IC50 533,9000 ppm dan senyawa kalkon (E)-1-(4-klorofenil)-3-(4-isopropilfenil)prop-2-en-1-on memiliki nilai IC50 718,9054 ppm. Kemampuan senyawa kalkon (E)-1-(4-klorofenil)-3-p-tolilprop-2-en-1-on dan (E)-1-(4-klorofenil)-3-(4-isopropilfenil)prop-2-en-1-on tergolong antioksidan lemah [12].

This service activity aims to increase students' knowledge about photosynthetic bacteria as plant fertilizers, so that they can increase student awareness to increase knowledge and it is hoped that knowledge can be used as capital for entrepreneurship. This activity also provides knowledge about photosynthetic bacteria starting from the understanding, characteristics to the working mechanism of bacteria. Methods and techniques of socialization consist of: planning, action and reflection. In planning, the preparation and dissemination of activities were carried out, at the action stage, the service was carried out starting with the exposure of photosynthetic bacteria, the working mechanism of bacteria and their benefits as plant fertilizers, and a question and answer session was held. The next stage is reflection, which is done by analyzing the participants' responses to the activities that have been carried out. In this service activity, the students were enthusiastic.

This study aimed to test the antioxidant activity of (E)-1-(4-chlorophenyl)-3-p-tolilprop-2-en-1-on (C1) and (E)-1-(4-chlorophenyl)-3- (4-isopropylphenyl)prop-2-en-1-on (C2). This research is useful as a first step in the search for alternative antioxidant compounds and new antibiotics from chalcone compounds. The antioxidant bioactivity test was carried out using the DPPH method. DPPH is a method that is fast, simple, and does not require high costs in determining antioxidant capacity using the free radical 2,2-diphenyl-1-picrylhydrazil (DPPH). This method is often used to test compounds that act as free radical scavengers or hydrogen donors and evaluate their antioxidant activity, as well as quantify the number of antioxidant-radical complexes formed. The antioxidant bioactivity of chalcone compounds (E)-1-(4-chlorophenyl)-3-p-tolilprop-2-en-1-on has an IC50 value of 533.9000 ppm and chalcone compounds (E)-1-(4-chlorophenyl) -3-(4-isopropylphenyl)prop-2-en-1-on has an IC50 value of 718.9054 ppm. The ability of chalcone compounds (E)-1-(4-chlorophenyl)-3-p-tolylprop-2-en-1-one and (E)-1-(4-chlorophenyl)-3-(4-isopropylphenyl)prop- 2-en-1-on is classified as a weak antioxidant [12]. Keywords : Antioxidant, DPPH, Chalcone
