Abstract

Guru dikatakan sebagai agen pembelajaran (learning agent) karenaguru berperan sebagai fasilitator, motivator, pemacu, perekayasapembelajaran, dan pemberi inspirasi bagi peserta didiknya. Kompetensiguru sebagaimana UU Republik Indonesia nomor 14 tahun 2005 meliputi:1) kompetensi pedagogik, 2) kompetensi kepribadian, 3) kompetensisosial,dan 4) kompetensi professional melalui pendidikan profesi. Berdasarkanpenjelaskan di atas dan juga kompetensi guru yang telah tercantum padaundang-undang, maka seorang guru harus a) mengenal peserta didiksecara mendalam; b) menguasai bidang studi baik disiplinilmu (diciplinarycontent) maupun bahan ajar dalam kurikulum sekolah (pedagogicalcontent); c) menyelenggarakan pembelajaran yang mendidik yaitumerencanakan dan melaksanakan pembelajaran, mengevaluasi proses danhasil belajar, serta tindak lanjut untuk memperbaiki dan melakukanpengayaan, serta; d) mengembangkan kepribadian dan profesionalitassecara bekelanjutan dan berkesinambungan.Lesson study adalah salah satu kegiatan yang dapatmengembangkan profesionalitas seorang guru. Lesson Study (dalamterminology bahasa Jepang dikenal dengan Jugyokenkyu) adalah suatukegiatan untuk meningkatkan kualitas pembelajaran di sekolah, baik dalampembinaan profesi guru melalui pengkajian pembelajaran secarakolaboratif dan berkelanjutan berdasarkan prinsip-prinsip kolegialitas danmutual learning, maupun dalam meningkatkan kualitas prosespembelajaran di kelas agar semua peserta didik mendapatkan kesempatanuntuk belajar bersama sesuai tingkat kemampuannya.Lesson Study merupakan suatu system kegiatan serta filosofinya.Oleh karena itu, jika ada tanggapan bahwa “LS adalah kegiatan kelompok’itu merupakan suatu kesalahpahaman. LS sebetulnya suatu kegiatan yangmeliputi penyusunan RPP (termasuk penyusunan silabus selama satutahun), melakukan open class (kegiatan pembelajaran), melakukan forumrefleksi (diskusi pasca pembelajaran), dan mengarsipkan catatan kegiatanpembelajaran

Abstract

T-2 toxin is a toxic and teratogenic mycotoxin produced by Fusarium tricintum which may contaminate cereal, seed, and food. The aim of this research is to find out the effects of T-2 Toxin on preimplantion embryos and fetuses of Swiss Webster mice. Pregnant female of Swiss Webster mice on 0 or 2 day of gestation was injected intraperitoneally with T-2 toxin at doses 0.05 or 0.10 mg/kg body weight (bw) and the dam was observed at 3.5 and 18 days of gestation. At 0 day of gestation, embryos were arrested at one to eight cell and uncompacted morulae stages (P < 0.01) compared to control, in both 0.05 and 0.10 mg/kg bw doses. The cell numbers of late blastocyst at all treated groups were decreased significantly compared to control. At 2 day of gestation, most of embryos were arrested on compacted morulae stage at dose 0.10 mg/kg bw (P < 0.01), the late blastocyst and its cell number were dose-dependently decreased. The live fetuses decreased significantly at all dose of T-2 toxin. No external malformation occurred in the fetuses. Results showed that T-2 toxin given at preimplantation stages inhibited development of preimplantation embryos as indicated by decreased number of live fetuses. Therefore, it was grouped as embryotoxic agent but those dosages did not cause malformation of the external appearance of Swiss Webster mice fetuses. Key words: Fusarium tricintum, T-2 toxin, mycotoxin, preimplantation embryos, embryotoxic
Methoxyacetic acid (MAA) causes digit malformations of mice when it was given orally on gestation day 11. Previous observation showed that malformation was caused by cell death.

Abstract

Methoxyacetic acid (MAA) causes digit malformations of mice when it was given orally on gestation day 11. Previous observation showed that malformation was caused by cell death. The aims of the research were to determine the types of cell death, first time of cell death and their distribution pattern on forelimb bud of Swiss Webster (SW) mice. Ten mM/kg of body weight (bw) of MAA were administered by gavage to SW mice on gestation day 11. Forelimb bud of mouse embryos of gestation day 11 + 0, 1, 2, 3, 4, 5 hours were processed with paraffin method and were made plantar section. Cell death at plantar section were colored with 4,6-diamino-2-phenylindole hydrochloride (DAPI) and hematoxylin. The result showed, that digit malformations initially by apoptosis mesenchymal cell at proximal of axial mesoderm in around of primary axial artery has done one hour after treatment. Apoptosis at the axial area, the site formation of digital ray III distributed to preaxial area where digits I and II are formed, and to the site formation of digits IV and V. The number of mesenchyme cell of digital rays II, III, and V was decrease by the increasing of gestation day, while digital ray was not formed and finally digits I, II, III, and V were missing. The reduction number of cell of digital ray IV were delayed time to be formed and its small size. Thereby it can be concluded, that MAA induced digit malformations of SW mice started by apoptosis which is occurrence has been increase in area of digital ray formation, so that digital ray can not be formed, but when formed it will not developed.

Abstract

Sangalang Hapakat Oyster Mushroom Farmers Group is a farmer group specializes in developing oyster mushrooms in Tanjung Sangalang Village, Central Kahayan District, Katingan Regency, Central Kalimantan Province. This farmer group has nine members, which currently sell seeds, baglogs, and oyster mushrooms to the community. To diversify oyster mushroom products and the knowledge of the group is still needed for oyster mushroom post-harvest processing training. Therefore, this service aims to provide training in oyster mushroom processing in product diversification to maximize the benefits obtained. The activity is divided into two stages: processing oyster mushrooms and online marketing of oyster mushroom products. The processing of oyster mushrooms into commercial food products has been successfully carried out at the Sangalang Hapakat Oyster Mushroom Farmers Group, Tanjung Sangalang Village. All farmer groups, especially mothers, can process oyster mushrooms into home food or commercial use. The products produced from this training are crispy mushrooms, mushroom satay, risoles, and shredded mushrooms. Besides, online marketing training provides knowledge to farmer groups in selling their products on various online market platforms and social media. The village's condition, which still has difficulties with internet access, has made the results of this online marketing training less optimal; however, the farmer groups have been able to market their mushroom products online.

Abstract

Kalampangan peat swamp forests in Central Kalimantan is home for Nepenthes spp. However, the number of Nephentes has been reduced due to massive forest fires and land conversion for housing and agricultural purposes. Nepenthes is a unique plant with ability to prey insects, hence often referred to as 'insectivorous plant'. This study investigates the distribution of Nepenthes spp. in Kalampangan forest through ground check and qualitative descriptive approach. A total of six observation plots measuring of 2m x 2m were used purposively. The results show there are four Nepenthes species found, namely Nepenthes gracilis, Nepenthes mirabilis, Nepenthes gracilis cortis, and Nepenthes ampularia. The highest Morisita index is 1.06 while the lowest one is 1.01.

Abstract

Preparation of hybrid coating material from modified epoxy polyurethane (ETP) and silan (Si) has been done. Epoxy and polyurethane were modified with silan using γ-Glisidoksil propil trimetoksisilan (GPTMS) and γ-aminopropyl triethoxysilane (γ-APS) and also dibutyltindilaurate (DBTL) as catalyst. Fourier Transform Infrared (FTIR) characterization indicated that the hybrid coating material has been formed. The results of the analysis of NCO percent and conversion rate of isocyanates (α) also verified that the ETP-Si hybrid coatings have been formed. The addition 30% of silane as Si-O group indicated the rest of NCO percent was the lowest for hybrid coating material with polyurethane concentration of 5% and 10. The composition of ETP5% - Si 30% was the optimum composition from the ETP-Si hybrid coating material based on the mechanical analysis.Key words: hybrid coating, polyurethane, epoxy, silane, ETP – Si
