ABSTRACTThis study was initiated by the students’ low learning outcomes on Chemistry subject and the teachers’ preference in using lecture method in teaching learning process.This study aimed at 1) finding out the differences of students’ learning outcomes between the use of flash media-assisted practical method and lecture method on hydrocarbon class at grade XI MIA of SMA Muhammadiyah I Pontianak. Using quasi experimental design and Control Group Posttes Design, this study employed the students of grade XI MIA 2 as the samples of experiment group, andthe students of grade XI MIA 2 as the samples of control group. The data collection techniques used were measurement and observation. While the instruments employed were observation sheet and essay. TheU-Mann Whitneytest revealed that the post test score of 0,0140< 0,05 Ho was rejected, while the Ha one was accepted. It means that there was correlation of students’ learning outcomes between the experiment and the control groups. In addition, the effect size result was 1,086 > 0,8 and considered high which indicated the positive effect of flash media-assisted practical method in enhancing students’ learning achievement.Keywords: flash, learning outcomes, hydrocarbon, practical method

Desa Sungai Limau, Kecmatan Sungai Kunyit memiliki pertumbuhan perkembangan usaha kuliner dan rumah makan karena terdapat sekolah serta perusahaan-perusahaan yang berada di desa tersebut. Hal ini memberikan dampk positif bagi masyarakat, namun namun juga menimbulkan dampak negatif dari sisi lingkungan. Dampak negatif dari usaha kuliner ini adalah volume limbah minyak goreng bekas (jelantah) yang tinggi. Ini terjadi karena masyarakat membuang minyak jelantah begitu saja. Limbah minyak jelantah apabila tidak dikelola dengan baik akan menjadikan lingkungan kotor dan dapat mencemari air serta tanah. Untuk mengatasi masalah itu, perlu inovasi dalam pengelolaan minyak jelantah dengan melibatkan masyarakat sehingga limbah dapat dimanfaatkan menjadi produk yang bernilai ekonomis. Salah satu potensi limbah minyak goreng adalah kandungan asam lemak yang tinggi sehingga dapat dimanfaatkan menjadi sabun cuci yang ramah lingkungan. Oleh karena itu, dilakukan kegiatan pengabdian masyarakat untuk meningkatkan nilai tambah minyak jelantah dengan mengolahnya menjadi sabun cuci piring. Pelatihan ketrampilan pengolahan minyak jelantah menjadi sabun cuci piring telah dilaksanakan bagi masyarakat di desa Sungai Limau, dan memberikan manfaat: 1) Masyarakat mengetahui dampak negatif minyak goreng bekas terhadap kesehatan dan lingkungan, 2) Masyarakat mengetahui dan terampil mengaplikasikan teknologi tepat guna pengolahan minyak jelantah menjadi sabun cuci.

The problematic issue of water shortages is always happens in dry season because of rainwater absorption in the peat soil which dominates most of the Borneo region especially Rantau Panjang subdistrict. The river water around peatlands area has typical smell, colour, and taste. Peat water has to be processed rightly before it is used to fulfill domestic needs. Therefore, there should be an effort to process the peat water appropriately through counseling and training in producing simple water purifier which is easy to operate. This dedication on the training in producing water purifier was conducted at Sebawi district in Sambas regency. There were 24 residents of Rantau Panjang subdistricts attended this training. The training began with the counseling in how to produce water purifier. The counseling aimed at transferring knowledge of the importance of clean water for the residents of Rantau Panjang subdistrict. The next activity was the training in producing water purifiers from simply and locally available materials. In this activity, the participants were given opportunity to practice producing water purifier. The participants were so enthusiastic in this training. Keywords: training, producing, water purifier equipment.

ABSTRAKThe importance of improving the quality of teaching is creating new innovations in designing new learning system so that students become more enthusiastic and motivated to achieve the expected learning outcomes. One way to measure the extent of improvement of the quality of learning is to develop assessment instruments that can be used to assess student learning outcomes. A proper assessment plays an important role in improving learning outcomes and in appreciation of the efforts made by learners. This study aimed to develop cognitive assessment instrument in School Chemistry I course for fourth semester students of chemistry education. Design and development of assessment instruments followed the 4D model, but only reached the stage of develop. Validity test of cognitive assessment instrument which was based on format suitability and display quality was tested to five experts. The results showed that cognitive assessment instrument had a valid level of validity and reliability value of 0.758. So cognitive assessment instrument developed already meet the criteria as a matter of quality and can be used as a test in the subject of School Chemistry I. Keywords: cognitive assessment instrument, School Chemistry I, Development ABSTRAK Pentingnya meningkatkan kualitas pembelajaran menuntut para pendidik menciptakan inovasi baru dalam merancang sistem pembelajaran baru agar peserta didik menjadi lebih semangat dan termotivasi sehingga dapat mencapai tujuan pembelajaran yang diharapkan. Salah satu cara yang dapat dilakukan oleh pendidik untuk mengetahui sejauh mana peningkatan kualitas pembelajaran adalah dengan membuat instrumen penilaian yang dapat digunakan untuk menilai hasil belajar siswa. Penilaian yang tepat berperan penting dalam meningkatkan hasil belajar dan sebagai penghargaan atas usaha yang telah dilakukan oleh peserta didik.

Approximately, 325 cultivars of bananas were found in Indonesia. They have variation in shape, taste, color of fruit pulp, essential vitamins and mineral. The Î²-carotene is one of essential nutrient in banana with various concentration in every cultivar. The aims of this research were to describe the morphological characteristics and to analyze Î²-carotene content of mature fruits of three different genomic groups of Indonesian dessert and cooking banana cultivars namely Berlin (AA/dessert), Barangan (AAA/dessert), and Kepok (ABB/cooking). Morphological characterizations of fruits were conducted according to Descriptor for Banana from International Plant Genetic Resources Institute. The Î²-carotene content of mature banana pulp was analyzed using High-performance liquid chromatography (HPLC) method with three replications. Banana fruit characters were analyzed based on 15 descriptors. The bananas were then subjected to clustering analysis. Â The result showed that Î²-carotene contentÂ were 27 Î¼g 100g-1, 5 Âµg 100g-1, and 3 Î¼g 100g-1 fresh weight respectively. Berlin showed the highest value of Î²-carotene. Cluster analyses formed two groups. The first group consists of Berlin and Barangan while the second one consists of Kepok. This study can be used as a a reference for people to consume bananas with high content of Î²-carotene in meeting the needs of vitamin A and as a consideration for the plant breeding especially for Î²-carotene improvement purpose.

Practicum is often not carried out in schools because of the limitations of practical tools. Therefore, it is necessary to develop practical tools to make it easier for students to understand the concept of thermochemistry. This study aims to produce a valid and practical thermochemistry practicum tool. Validity is measured from the material and media aspects using a validation sheet. Meanwhile, practicality was measured using teacher and student response questionnaires. This type of research is research and development (research and development) ADDIE model (analysis, design, development, implementation, and evaluation). The results of the analysis show that the thermochemical practicum tool developed is declared to be very valid with an average value of 0.94 and 0.92. The results of the practicality test obtained very practical criteria in the initial field trial and the main field trial an average of 94.64% and 97.92%, respectively. Thus, the thermochemistry practicum tool developed is suitable to be used as a medium for learning thermochemical material.
