Abstract

Abstract: The purpose of this research was to determine the influence of challenge based learning model on students creative thinking ability. This research is used a quasy-experimental design of the type nonequivalent pretest-posttest control group design. The sample of this research consisted of students of Chemistry Education, Khairun University in the sixth semester, enrolling in the subject of Environmental Chemistry during education year in 2018/2019 from two classes. The experimental class was taught with challenge based learning model and the control class was taught with problem based learning model. The instrument of the research was a creative thinking ability tests with the type of open essay questions that had validity of 77.08% and Alpha Cronbach reliability coefficient of 0.896. The results showed that there was no statistically significant difference in creative thinking ability between the  students from the two research classes (? = 0.05), although descriptively the creative thinking ability of the experimental class was better than the control class.Abstrak: Tujuan penelitian ini adalah untuk mengetahui pengaruh model challenge based learning terhadap kemamampuan berpikir kreatif mahasiswa.

Abstract

Abstrak: Tujuan kegiatan pengabdian ini adalah memberikan slusi untuk pengelolaan limbah ternak. Peternakan sapi merupakan sumber penghasilan bagi masyarakat pedesaan.  Dampak peternakan salah satunya limbahnya mengganggu lingkungan, berbau tidak enak dan sumber penyakit.  Masyarakat umumnya belum bias mengolah limbah menjadi biogas.   Biogas berpotensi menggantikan penggunaan LPG, yang dapat digunakan untuk memenuhi kebutuhan bahan bakar warga. Metode yang digunakan dalam adalah pelatihan dan pendampingan. Hasil kegiatan ini adalah telah pemahaman peternak tentang proses pengolahan limbah dan terwujudnya reaktor pengolah limbah dengan model kubah tertanam dalam tanah berkapasitas 6 kubik.  Reaktor ini memberikan manfaat berupa energi gas yang dialirkan ke kompor serta siap digunakan memasak cukup untuk keluarga 3-4 orang.Abstract: the purpose of this service activity is to provide slusi for livestock waste management. Cattle farming is a source of income for rural communities. One of the impacts of animal husbandry is that the environment disturbs, smells bad and is a source of disease. The general public cannot yet process waste into biogas. Biogas has the potential to replace the use of LPG, which can be used to meet the fuel needs of citizens. The method used in the training and assistance. The results of this activity are farmers' understanding of the waste treatment process and the realization of a waste treatment reactor with a dome model embedded in a 6 cubic-capacity soil. This reactor provides benefits in the form of gas energy which is flowed to the stove and is ready to use enough cooking for a family of 3-4 people.

Abstract

Pendidikan memegang peranan penting dalam era globalisasi sehingga perlu dilakukan perubahan dan perbaikan untuk meningkatkan kualitas pendidikan nasional. Upaya pembaharuan dalam bidang pendidikan dilakukan melalui penerapan kurikulum berbasis kompetensi (KBK). KBK mengarahkan pada proses pembelajaran konstruktivistik agar siswa dapat membangun pengetahuannya melalui serangkaian proses pembelajaran. Salah satu model pembelajaran yang mengacu pada proses pembelajaran konstruktivistik adalah model pembelajaran Learning Cycle 5 Fase. Tujuan penelitian adalah mengetahui perbedaan hasil belajar antara siswa yang diajar dengan model pembelajaran Learning Cycle 5 Fase dengan siswa yang diajar dengan pembelajaran konvensional. Penelitian menggunakan rancangan eksperimental semu. Populasi penelitian adalah siswa kelas XI SMA Negeri I Talun pada tahun ajaran 2006/2007. Sampel dalam penelitian terdiri dari kelas eksperimen dan kelas kontrol yang diambil secara acak kelas. Teknik analisis data yang digunakan adalah analisis statistik dan analisis deskriptif. Hasil penelitian menunjukkan bahwa ada perbedaan hasil belajar siswa yang diajar menggunakan model pembelajaran Learning Cycle 5 Fase dibandingkan dengan pembelajaran konvensional, dimana rata-rata nilai hasil belajar siswa yang diajar dengan model pembelajaran Learning Cycle 5 Fase lebih tinggi (81,13) daripada dengan pembelajaran konvensional (74,53).

Abstract

The 9-(4-Methoxyphenyl)-3,3,6,6-tetra-3,4,5,6,7,9-hexahydro-2H-xantene-1 compound, which is addressed as compound 1 in this study, is the derivatives of 1,8-dioxo- octahydroxantene. This compound has a carbonyl group and double bond on beta carbon toward the carbonyl group and benzene ring. The presence of this chromophore helps the compound creates intermediate stabilized by resonance from its interaction with free radicals and has the potential to be an antioxidant. Compound 1 was synthesized from p- methoxybenzaldehyde and dimedone through Knoevenagel condensation reaction using an acid as catalyst. The lime and lemon juice was selected as a catalyst to support green chemistry principle. The obtained product includes white powder with a melting point of 222-224oC. The IR analysis results, GC-MS, and 1H-NMR data show that the compound structure of Compound 1. Meanwhile, the antioxidant activity test using the DPPH method reveal that Compound 1 has the antioxidant activity with IC50 of 22.74 ppm.

Abstract

Kelompok tani wilayah ponggok berpotensi sebagai penghasil  produk agro seperti buah-buahan dan juga minyak atsiri seperti bunga kenanga, nilam, sereh dan  cengkeh. Minyak atsiri dapat diisolasi dengan cara destilasi  air, dan destilasi air-uap. Masyarakat banyak menghasilkan limbah minyak goreng. Limbah minya tidak baik untuk kesehatan dn juga mencemari lingkungan. Hasil potensi desa bisa dimanfaatkan sebagai unggulan masyarakat desa. Dengan reaksi saponifikasi minyak dapat diubah menjadi sabun. Hasil kegiatan ini menunjukkan bahwa masyarakat sangat antusias dan bisa membuat sabun cair dengan bahan baku minyak goreng, dikatalis  basa, sedikit texafone, serta gloserin serta sedikti aroma minyak aisiri.  Kata kunci—minyak atsiri, sabun, minyak sawit, masyarakat desa. Abstract Ponggok area farmers groups have the potential to produce agro products such as fruits and essential oils such as cananga, patchouli, lemongrass and clove. Essential oils can be isolated by water distillation, and water-steam distillation. Many people produce cooking oil waste. Oil waste is not good for health and also pollutes the environment. Village results can be used as a superior village community. With the saponification reaction the oil can be turned into soap. The findings of these activity showed that the community is very enthusiastic and can make liquid soap with raw materials for cooking oil, alkaline catalysts, a little texafone, as well as gloserin and a little aroma of essential oils. Keywords—essential oil, soap, palm oil, rural communities
