Abstract

A research on mangrove forest at coast Cengkrong in the village of Karanggandu aimed at defining zoning and composition of magrove vegetation. The sampling method consists of 3 zoning. Each zone established 3 plots, consists of 10 m x10 m plot size of trees category, 5 m x 5 m of stake category, and 1 m x 1 m of seedling category to repeat in 3 times. Data analysis of mangrove vegetation employed Improtance Value Indeks (IVI). The research results found 12 mangrove species namely Avicennia alba, Bruguiera gymnorrhiza, Bruguiera parviflora, Ceriops decandra, Ceriops tagal, Lumnitczera racemosa, Rhizophora apiculata, Rhizophora mucronata, Sonneratia alba, Sonneratia caseolaris, Xylocarpus granatum Nypa fruticans. Reffering to the the mangrove zonation indicates the zone I or open zone grows Sonneratia alba and it can be found Rhizophora mucronata, Ceriops decandra with salinity of 6 ppt. Zone II or middle zone grows species of Avicennia alba and it also be found Sonneratia alba, Xylocarpus granatum with salinity of 6 ppt. Zone III or zone that is closer to the landward grows species Xylocarpus granatum and also appears Lumnitzera racemosa,Bruguiera parviflora with salinity of 4 ppt. It showed that the formation of mangrove zonation at Coast Cengkrong is still categorized as less stable, due to rehabilitation since 2002 were done without understanding the type of site suitability and natural factors which causes the fruits drop when the tides of sea water, so that the growth is not stable.

Abstract

The aim of this research was to determine the analysis of science process skills in textbooks of chemistry grade XI in SMA N 1 Teras, Boyolali. This research used the descriptive method. The instruments were developed based on 10 indicators of science process skills (observing, classifying, finding a conclusion, predicting, raising the question, hypothesizing, planning an experiment, manipulating materials, and equipment, Applying, and communicating). We analyzed 3 different chemistry textbooks that often used by teachers in teaching. The material analyzed in the book was solubility and solubility product concept in terms of concept explanation and student activity. The results of this research showed different science process skill criteria in 3 different chemistry textbooks. Book A appeared 50% of all aspects of science process skills, in Book B appeared 80% of all aspects of science process skills, and in Book C there was 40% of all aspects of the science process skills. The most common indicator in all books was observing (33.3%), followed by prediction (19.05%), classifying (11.90%), Applying (11.90% ), planning experiments (9.52%), manipulating materials and equipment (7.14%), finding conclusion (4.76%), communicating (2.38%). Asking the question and hypothesizing did not appear in textbooks.

Abstract

ABSTRAK   Limbah plastik memiliki permasalahan lingkungan yang cukup serius. Polipropilen (PP) merupakan salah satu limbah plastik yang jumlahnya cukup banyak di lingkungan kita. Daur ulang limbah plastik polipropilen menjadi bioplastik ramah lingkungan merupakan salah satu solusi yang dapat dilakukan untuk mengurangi permasalahan lingkungan. Tujuan penelitian ini untuk mengetahui pengaruh penambahan kitosan terhadap biodegradasi plastik berbahan dasar polipropilen. Dalam penelitian ini, limbah polipropilen digunakan sebagai matriks dengan kitosan sebagai filler dan dikumil peroksida (DCP) sebagai crosslink agent. Kitosan dengan berbagai komposisi sebesar 0, 5, 10, 15, 20 dan 5 + 1% DCP fraksi massa ditambahkan ke dalam polipropilen. Pembuatan plastik dilakukan  dengan metode blending. Bioplastik yang diperoleh selanjutnya dikarakterisasi gugus fungsi dan sifat biodegradasinya berturut-turut dengan FTIR dan perendaman dalam mikroba campuran (mixed microbial batch) dengan EM4. Pada uji biodegradasi didapat plastik yang paling degradabel adalah plastik dengan komposisi PP: Kitosan (% w/w) 80/20. Selanjutnya urutan biodegradabilitas berturut-turut adalah dengan perbandingan 85/15; 90/10; 95/ 5;  90/10 + 1% DCP; 100/0.   Kata kunci: Polipropilen, Kitosan, Dikumil Peroksida, Biodegradasi

Abstract

The purpose of this study was to determine the profile of critical thinking skills of senior high school students. The paper-based essay questions and the questionnaires were used as the instruments to measure critical thinking skills in daily chemistry problems, which is based on Facione’s critical thinking aspects included interpretation, analysis, evaluation, inference, explanation, and self-regulation. The research was conducted in one of government senior high school in Central Java, Indonesia. The descriptive-qualitative method was used for the research method. The qualitative approach was used to analyze the data by using essay questions and questionnaires. The criteria for critical thinking skills were categorized as null, low, medium, and high. The result showed that most of the students have weak or low skill in critical thinking, especially in analysis, evaluation, explanation, and self-regulation whether their skill of interpretation and inference are medium. This finding can be used to develop a new strategy in teaching chemistry related to critical thinking skill.

Abstract

The success of the learning process is something that needs to be considered in 21st-century learning. One of the successes in teaching and learning uses appropriate learning models. One of the 21st-century learning models is the 5E Learning Cycle integrated with Science, Technology, Engineering, and Mathematics (STEM). This learning model encourages student activities in the teaching and learning process, with the encouragement of student activities, students' science process skills will grow. Science process skill is one of skill that student must have in 21st-century learning. One effort to encourage students' process skills is to use a virtual laboratory. This research aims to develop a 5E Learning Cycle module integrated with STEM and is equipped using a virtual laboratory (www.chemcollective.org) on thermochemistry material. This study's subjects were students of class XI of state high schools in the city of Kediri. This research is a Research and Development (R&D). The data collected through interview, observation, and questionnaires. The results of this study are: students need a teaching material that can drive the student achievement of the teaching and learning process in the 21st century in thermochemistry material; module validity which is declared valid by a severe expert (v = 0.89); The module developed shows effective results seen from the learning outcome on thermochemistry material and the module can foster science process skill

Abstract

Colloidal nanocomposites silver-chitosan have been made. Silver nanoparticles were produced by chemical reduction methods assisted microwave irradiation using chitosan from crab shells as a reducing agent and stabilizer, AgNO3 as a precursor and NaOH as an accelerator. This study investigated AgNO3 concentration toward localized surface plasmon resonance (LSPR) phenomenon of nanocomposites colloidal. The size and shape of the silver nanoparticles were confirmed by TEM. Furthermore, the stability of the storage was observed for twelve weeks. Colloidal and film nanocomposites silver- chitosan have been made by casting method by drying at room temperature. After that, the film characterization was carried out, including swelling with gravimetry methods and surface morphology using scanning electron microscopy (SEM). Diffusion methods tested colloid antibacterial activity and silver-chitosan nanocomposite film’s against E. Coli and S. Aureus. The results showed that the formation of silver nanoparticles was identified by the LSPR absorption band's appearance at 413-419 nm. The increasing of AgNO3 concentration increased the intensity of the LSPR absorption band. Silver nanoparticles with sizes of about 3-9 nm are spherical. The silver nanoparticles were stable at 12 weeks of storage. The higher AgNO3 concentration tends to increase the swelling of the film. The surface of the silver-chitosan nanocomposite film’s was rougher than that of the chitosan film. The higher the silver nanoparticle concentration, the higher the colloid and film antibacterial activity against E. Coli and S. Aureus.
