<![CDATA[Penelitian ini bertujuan untuk pengabdian kepada masyarakat dalam rangka bimbingan menulis proposal dan melaksanakan penelitian tindakan kelas (PTK) serta membuat laporan PTK dalam bentuk artikel bagi guru-guru kimia agar dapat dipublikasikan pada jurnal Nasioanl atau Internasional. Penelitian ini dilakukan di SMAN 1 Kota Bukittinggi selama 2 hari dengan jumlah peserta 13 orang guru kimia. Dalam pelaksanaan bimbingan ini dilakukan 4 metode. Pertama, metode ceramah ketika penyampaian materi; kedua, metode tanya jawab; ketiga, praktik pelaksanaan didampingi oleh tim ahli; keempat, diskusi untuk mengidentifikasi keberhasilan peserta. Sebelum dan sesudah kegiatan peserta diberikan angket mengenai keperluan peserta terhadap materi serta pemahaman peserta terhadap materi. Dalam kegiatan ini peserta dapat mengetahui permasalahan dikelas dan juga cara penelusuran artikel PTK secara online, metode dan Teknik penulisan artikel hasil PTK, teknik submit artikel hasil PTK kepada jurnal Nasional, serta penggunaan program Mendeley untuk mempermudah penulisan sitasi dan daftar pustaka pada artikel. Hasil pemahaman peserta sebelum penyampain materi dengan setelah penyampaian materi mengalami kenaikan yang signifikan yang ditandai dengan kenaikan jumlah pesrta yang paham. Dengan adanya bimbingan penulisan artikel dan penyusunan PTK ini memberikan motivasi kepada guru untuk membuat karya ilmiah berupa artikel hingga dapat dipublikasi.]]>

<![CDATA[Learner Worksheet (LKPD) of reaction rates based structured inquiry in class XI SMA had been dertemine validity and practicality. The type of research used is Research and Development (R and D). The development model was a 4-D model consisting of 4 stages, namely (1) Define, (2) Design, (3) Develop, (4) Disseminate. The disseminate stage was not carried out due to time and cost constraints. The research instrument used was a questionnaire validation and practicality questionnaire. The validation questionnaire was filled by 3 chemistry lecturers from FMIPA UNP and 2 chemistry teachers from SMAN 2 Lubuk Basung. Practicality questionnaire was filled by 2 chemistry teachers and 30 students of class XII MIPA 3 SMAN 2 Lubuk Basung. Data were analyzed using kappa moments. The average kappa moment of validity test was 0.87 with a very high validity category. The average kappa moment of teacher were 0,88 with a very high practicality category. The average kappa moment of student were 0,87 with a very high practicality category. Thus, it was concluded that reaction rates LKPD based on structured inquiry was valid and practice.]]>

<![CDATA[The 2013 curriculum requires teachers to use a scientific approach in teaching-learning process. The scientific approach is in accordance with the steps of various learning models, one of which is guided discovery. The study aimed at developing guided discovery modules on material buffer solutions for class XI SMA or MA and determining the validity and practicality of the developed modules. The research type was Research and Development. The development model was 4-D models that consists of four steps: define, design, develop, and disseminate. The research was limited to. The instrument of the research was questionnaire a form that consist of validity and practicality sheets. The module was validated by 5 validators and module practicality was examined by 2 chemistry teachers and 34 students of grade XI MIA 1 at SMAN 12 of Padang. Validity and practicality data were analysed by using the kappa Cohen formula. The moment kappa average of 5 validators was 0.90 with highest validity category. The moment kappa average of teachers and students were 0.8 and 0.86 spelling with the high category. The result of the research showed that the module of buffer solutions based on guided discovery with multiple representations was valid and practice to be used on the learning of chemistry.]]>

<![CDATA[This study is research and development (R and D) and using 4-D models, but disseminate step is not done. Validation of student worksheets has been done by chemistry lecturers and chemistry teachers. The practicality of student worksheets has been done by chemistry teachers and students of 2nd grade of SMAN 1 Pariaman. The result showed that moment kappa average of validity was 0,83 with very high validity category and moment kappa average of practicality were 0,9 by chemistry teachers and 0,86 by students with very high category. Therefore student worksheets of molecular shape based on structured inquiry with emphasis on the submicroscopic level using 3-D models is valid and practice to be used on the chemistry learning.]]>

<![CDATA[Genotypic identification of bacteria is faster than phenotypic identification. This study aims to determine the group of lactic acid bacteria species from Tilatang Kamang Agam curd using the 16S rRNA gene. Bacterial chromosomal DNA was isolated using the kit wizard genomic DNA purification method. The 16S rRNA gene in chromosomal DNA was isolated by PCR method using BacF1 and UniB1 primers. The 16S rRNA gene fragment sequencing was carried out using the Dideoxy Sanger method. The sequenced nucleotide base sequences were analyzed using the BioEdit, BLASTn and MEGA X programs. The size of the 16S rRNA gene fragment of the bacterial isolate UBC-DTK-01 obtained was 1017 bp (base pair). The bacterial isolates belonged to the Enterococcus genus and Enterococcus faecalis species strain UBC-DTK-01.]]>
