Understanding the concept of biology is necessary in the integration of nature and technology in everyday life, if the concept of understanding is strong, students can develop and understand higher concepts. But sometimes students have a different understanding of concepts with scientifically accepted concepts and that will lead to misconceptions. The purpose of this study is to determine whether there is misconception in students and sub-concept what most misconception in reproduction system material. To calculate the misconception level of the Certainty of Response Index (CRI) method with the subjects of the study were students of class XI SMA 2 Cikampek. The data can show students misconception for some sub-concepts. The highest misconceptions exist in the menstrual subconses, which is 32.5% while the lowest is in the 10% gamete formation subconsep. This is because students interpret their own understanding of a material based on a text book that is read and an explanation from the teacher.

ABSTRAKStaphylococcus aureus merupakan bakteri dengan prevalensi tertinggi pada luka ulkus diabetikum yang dapat memperlambat proses penyembuhan luka. Hal ini kemudian diperparah dengan adanya resistensi terhadap berbagai antibiotik. Kopi dapat menjadi alternatif lain mengatasi resistensi antibiotik karena memiliki senyawa antibakteri, namun pemanggangan pada biji kopi akan menurunkan senyawa yang bertanggung jawab terhadap aktivitas antibakteri. Penelitian ini bertujuan untuk mengidentifikasi perbedaan aktivitas antibakteri ekstrak biji hijau dan sangrai kopi robusta (Coffea canephora L.) terhadap Staphylococcus aureus. Penelitian ini menggunakan desain post-test only control group dengan metode agar difusi cakram (Kirby-bauer). Sampel dibagi menjadi 13 kelompok, yaitu kontrol positif clindamycin, kontrol negatif aquades steril, kelompok perlakuan ekstrak biji hijau dan sangrai kopi robusta (25%, 50%, dan 100%), serta kelompok perlakuan kombinasi ekstrak biji hijau dan sangrai kopi robusta (50%:50%, 75%:25%, 25%:75%, 60%:40%, dan 40%:60%). Hasil analisis One Way Anova terhadap kelompok kontrol dan perlakuan didapatkan p=0,000. Hasil analisis Post Hoc Tukey HSD terhadap seluruh kelompok perlakuan dibandingkan dengan kelompok kontrol negatif didapatkan p=0,000. Zona hambat terbesar ditemukan pada kelompok kombinasi ekstrak 50%:50% dengan diameter sebesar 15,12 mm dan memiliki efek antibakteri yang sebanding dengan clindamycin dalam menghambat Staphylococcus aureus (p=0,121). Kata kunci : Aktivitas antibakteri; Biji hijau; Biji sangrai; Kopi Robusta (Coffea canephora L.); Staphylococcus aureusABSTRACTStaphylococcus aureus is the bacteria with the highest prevalence in diabetic ulcers which can be delayed the wound healing process. This is then exacerbated by the existence of resistance to various antibiotics. Coffee can be another alternative to overcome antibiotic resistance because it has antibacterial compounds, but roasting coffee beans will reduce the compounds responsible for antibacterial activity. The aim of this study is to identify antibacterial activity differences between green and roasted bean robusta coffee (Coffea canephora L.) extract and its combination against Staphylococcus aureus. This research used a post-test only control group design with an agar disc diffusion method (Kirby-bauer). Samples were divided into 13 groups, positive control clindamycin, negative control water sterile, green and roasted bean robusta coffee extract treatments group (25%, 50%, and 100%), and its combination (50%:50%, 75%:25%, 25%:75%, 60%:40%, and 40%:60%). One Way Anova test results on the control and treatment groups obtained p=0.000. Post Hoc Tukey HSD test results of all treatments compared to the negative control group obtained p=0.000. The largest inhibition zone was found in a 50%:50% extract combination with 15.12 mm in diameter , and its antibacterial effect was equal to clindamycin in inhibiting Staphylococcus aureus (p=0.121). Keywords : Antibacterial activity; Green bean; Roasted bean; Robusta Coffee (Coffea canephora L.); Staphylococcus aureus

Kejibeling leaf as one part of the plant that is used as a natural medicine with various therapeutic effects. Plant extracts used as medicinal ingredients generally have poor solubility and result in low oral bioavailability. Kejibeling leaf extract is less soluble in water, so its pharmacologic effect is limited. Nanoemulsions can be an option for delivery systems which are expected to increase the solubility and bioavailability of oral administration. Nanoemulsifying formulation can be done through Self-Nanoemulsifying Drug Delivery System (SNEDDS). Simplex Lattice Design (SLD) is one of the optimization methods that can be used. This method is used to provide convenience in determining the optimal formula for the SNEDDS mixture. Testing on 14 formulas from Simplex Lattice Design resulted in the optimal formula for SNEDDS leaves of kejibeling with a composition of 2.22 (VCO): 54.23 (surfactant) : 43.55 (cosurfactant) with a transmittance value of 98.95% and an emulsification time of 47.12 seconds. Has a particle size of 11 nm with a PI value of 0.167 and a zeta potential value of -31.2 mV.

ABSTRAKPertumbuhan kosmetik di Indonesia semakin pesat sesuai dengan penggunaan kosmetik yang semakin meningkat, terutama dikalangan wanita. Sediaan kosmetik yang digunakan oleh kalangan wanita adalah liptint ekstrak lidah buaya (Aloe vera L.). Pembelian kosmetikpun saat ini semakin mudah karena adanya toko online atau e-commerce. Akan tetapi, kosmetik adalah produk yang cukup beresiko jika tidak dilihat dan dicoba secara langsung karena dapat mengandung zat pewarna berbahaya yaitu Rhodamin B. Rhodamin b merupakan zat warna sintesis yang digunakan untuk industri cat, tekstil dan kertas. Rhodamin B sering disalahgunakan karena warnanya lebih cerah dan harganya murah. Penelitian ini bertujuan untuk mengidentifikasi zat pewarna berbahaya rhodamin b didalam 8 sampel liptint yang dibeli secara online di e-commerce dan menghitung kadar rhodamin b yang terdapat didalam sampel yang positif mengandung rhodamin B. Uji kualitatif menggunakan rapid test kit rhodamin b yang terdiri dari 2 reagen yaitu reagen I dan reagen II dan uji kuantitatif mengunakan Spektrofotometri UV-Vis. Hasil dari uji kualitatif dengan menambahkan reagen test kit I dan II terjadi perubahan warna pada sampel A1, A2 dan A7 menjadi merah keunguan yang berarti positif mengandung rhodamin b. Hasil dari uji kuantitatif menggunakan spektrofotometri UV-Vis didapat kadar rhodamin b pada sampel A1 yaitu sebesar 0,012 mg/g, sampel A2 sebesar 0,017 mg/g dan sampel A7 sebesar 0,019 mg/g. Dari 8 sampel yang telah diuji didapat 3 sampel positif mengandung Rhodamin B. Kadar Rhodamin B yang terdapat pada ketiga sampel tersebut tergolong sedikit, tetapi dalam jangka panjang dapat menimbulkan efek toksik pada tubuh dan menyebabkan kanker. Kata kunci : Rhodamin B; Lip tint; E-commerce; Spektrofotometri uv-visABSTRACTThe growth of cosmetics in Indonesia is increasing rapidly in accordance with the increasing use of cosmetics, especially among women. Aloe vera (Aloe vera L.) extract and liptint are cosmetic preparations used by women. Purchasing cosmetics is now even easier because of online stores or e-commerce. However, cosmetics are products that are quite risky if they are not seen and tried directly because they can contain dangerous dyes, namely Rhodamine B. Rhodamine B is a synthetic dye used for the paint, textile, and paper industries. Rhodamine B is often abused because it is brighter in color and cheaper. This study aims to identify the harmful dye rhodamine B in 8 samples of liptint purchased online at e-commerce and calculate the levels of rhodamine B contained in samples that are positive for rhodamine B. A qualitative test using a rapid test kit rhodamine B consisting of 2 reagents, namely reagent I and reagent II, and a quantitative test using UV-Vis Spectrophotometry. The results of the qualitative test by adding the test kit reagents I and II showed a color change in samples A1, A2 and A7 to purplish red, which means they contain rhodamine b. The results of the quantitative test using UV-Vis spectrophotometry showed that the levels of rhodamine b in sample A1 were 0.012 mg/g, sample A2 was 0.017 mg/g, and sample A7 was 0.019 mg/g. Of the 8 samples that have been tested, 3 positive samples contain Rhodamine B. The levels of rhodamine B in the three samples are relatively low, but it can have toxic effects on the body and cause cancer in the long run. Keywords : Rhodamin B; Lip tint; E-commerce; Spektrofotometri uv-vis
