    Trans Metro Pekanbaru (TMP) is public transportation that has been operating since 2009 in Pekanbaru. It has function to reduce the problems related to public transport and traffic that appear because of the development of the city itself. During the time, the changing of passenger quantity, service quality and operation could happen anytime. Therefore, this research was done to find out the effectivity of Trans Metro Pekanbaru corridor II that serves the transportation from Terminal Bandar Raya Payung Sekaki (BRPS) to Kulim with the load factor as the indicator. The aim of this research is to determine the value of load factor and analyze the characteristic of Trans Metro Pekanbaru route that refer to the changing of load factor value, especially to the corridor of Terminal BRPS- Kulim. The results of this research were TMP busses of Corridor II which were not effective yet if we concern from the number of passenger, because the most of the load factor on this corridor has not appropriate the standard load factor value yet, based on the SK Dirjen No. 687 at 2002 (70%), so it was not optimal in serving the movement of passengers. Based on the result of the analysis, the characteristics of Trans Metro Pekanbaru Corridor II has value load factor greater than 70% were in the holiday period from Terminal Bandar Raya Payung Sekaki to Kulim was the Kantor Pos shelter - Metro Plaza 1 shelter that is a transit shelter in the city center and shelter at the shopping center. From the results of statistical tests that have been performed, the selection mode equation Trans Metro Pekanbaru is : Y = 5.75 - 0.061 X1 + 0.008 X2 + 0.000 X3 + 0.005 X4. Attributes considered is the waiting time (X1), speed (X2), rate (X3) and the convenience vehicles (X4)

    Berbagai media dan metode yang digunakan oleh guru multimedia seperti penemuan, diskusi, penugasan, tampaknya belum mampu memfasilitasi siswa untuk belajar lebih serius. Menurut Asosiasi Penyedia Layanan Internet Indonesia (APJII) pada tahun 2012, sekitar 63 juta orang Indonesia terhubung ke internet dan sebanyak 95 persen dari kegiatan yang mereka lakukan adalah media sosial terbuka. Jadi melalui media sosial telegram, pengetahuan yang disampaikan akan lebih menarik. Penelitian ini menggunakan model pengembangan "ADDIE" yang memberikan gambaran umum tentang tahapan-tahapan pengembangan media sosial telegram dalam salah satu mata pelajaran jurusan multimedia di SMK Negeri 4 Surabaya, agar data yang diambil bisa terstruktur. Menganalisa hasil validasi media dan perangkat pembelajaran oleh validator, kemudian menganalisa hasil data pretest dan posttest siswa sehingga dapat diketahui pengaruh dari pengembangan media sosial telegram terhadap hasil belajar siswa. Hasil analisis data pada Pengembangan Media Sosial Telegram di SMK Negeri 4 Surabaya dapat diketahui dari meningkatnya hasil belajar siswa setelah menggunakan media pembelajaran berbasis telegram. Oleh karena itu, media pembelajaran sangat layak digunakan, karena dapat dilihat dari meningkatnya kemampuan berfikir kognitif siswa dan media sosial telegram layak digunakan sebagai penunjang proses pembelajaran di dalam kelas

    Limbah whey dari produksi pembuatan tahu dapat menimbulkan pencemaran lingkungan jika dibuang begitu saja, sehingga membutuhkan penanganan melalui pengolahan menjadi produk yang bernilai ekonomis seperti sabun padat. Tujuan penelitian ini adalah memformulasi sabun padat berbahan baku limbah whey serta melakukan uji organoleptik, pH, dan tinggi busa. Formulasi (%) antara limbah whey tahu dan olive oil adalah F1 (20 dan 0,5), F2 (20 dan 1) dan F3 (20 dan 2). Diawali dengan pembuatan sabun padat menggunakan metode eksperimental, menguji tinggi busa melalui uji deskriptif dengan metode observasional analitik, dan uji organoleptik dan pH melalui uji deskriptif. Hasil penelitian ini adalah semua formula sabun padat memiliki efektivitas yang baik, ketinggian busa telah memenuhi SNI 06-4085-1996, tetapi memiliki pH yang lebih besar dari pH SNI 06-4085-1966. Sediaan sabun padat yang terbaik adalah formula 1 (F1), karena memiliki nilai pH yang mendekati nilai pH SNI tersebut

    Biological evaluation tools are very important. The current reality is that biology evaluation tools are rarely used in learning because of limited tools, materials and time. One of the efforts made is to develop a computer/PC-based KUMAL (Kuis Animalia) game application. The aim is to determine the feasibility of the KUMAL game developed as a learning evaluation tool on animalia material. The research was conducted using Research and Development (R&D) research and development methods. The samples in this study were 3 material experts, 3 media experts and 3 IT experts.           The validation results from this study are 84% with a very feasible category from the material validator, 83% with a very feasible category from the media validator and 83% with a very feasible category from the IT validator. The conclusion of this study is that the KUMAL game is feasible to be used as an evaluation tool for biology learning in animalia material for class X SMA/MA

    Xylanase can be used as an alternative material in the pulp bleaching process to reduce the use of chemicals in the paper industry. Bacillus subtilis is a type of bacteria that can produce xylanase. Xylanase characterization is needed to determine the maximum activity that will be used in the pulp bleaching process. This study aims to determine the xylanase characterization of Bacillus subtilis in terms of optimal pH, optimal temperature, carbon source, and optimal nitrogen source. The research material used was a pure culture of Bacillus subtilis bacteria obtained from the Biochemistry Laboratory of the Department of Chemistry, Faculty of Mathematics and Natural Sciences, Brawijaya University. The characterization of the xylanase enzyme was carried out using the RAL method. The results of characterization of the determination of pH, temperature, carbon source, and nitrogen xylanase source from Bacillus subtilis showed that the optimum conditions for xylanase were at pH 7 with a maximum activity of 5.085 U / mL; the optimum temperature at 40oC with activity 8.017 U/mL; maximum carbon source at a concentration of 15% (b/v) with activity 7.517 U/mL; and the optimum source of nitrogen with a concentration of 0.17% (b/v) with an activity of 4.815 U/mL

    Penelitian ini dilakukan untuk mengaji respons metafisis tulang femur distalis tikus ovariektomi yang mengonsumsi suplemen kalsitriol selama enam minggu. Lima belas tikus Wistar umur delapan minggu, secara acak dibagi tiga kelompok (normal/N, ovariektomi/Ov, dan ovariektomi + kalsitriol/OvD) masing-masing 5 tikus. Tikus kelompok N dan Ov diberi pakan standar, sedangkan tikus kelompok OvD diberi pakan standar + kalsitriol. Pada umur 14 minggu, tikus dimasukkan kandang metabolik individu untuk studi balan. Pada hari 4-7 studi balan, setiap hari sisa pakan, urin, dan feses dikoleksi untuk pemeriksaan Ca. Pada akhir penelitian, tikus dieutanasia, tulang femur kanan diambil pemeriksaan histopatologis dengan pengecatan hematoksilin dan eosin. Hasil penelitian menunjukkan bahwa konsumsi Ca dan retensi Ca pada tikus OvD tidak berbeda signifikan meskipun cenderung meningkat, sedangkan ekskresi Ca dalam feses dan urin meningkat sangat signifikan (P0,01). Metafisis tulang femur distalis tikus kelompok OvD terlihat zona spikulum tulang trabekula lebih pendek dan berbentuk irreguler, dan rongga sumsum tulang didominasi jaringan adiposit. Dari hasil penelitian dapat disimpulkan bahwa suplementasi kalsitriol selama enam minggu pada tikus ovariektomi menyebabkan osteoporosis pada metafisis tulang femur distalis

    The growth of Salmonella thypi and Listeria monocytogenes bacteria can be inhibited by butterfly pea flower kombucha. This is because telang flower kombucha has pharmacological activity so it can be developed in the pharmaceutical field. This research needs to be carried out to make hand washing soap made from an active solution of telang kombucha diffusing solution so that it can stop the growth of Salmonella thypi and Listeria monocytogenes bacteria. The research method uses laboratory experiments. The data obtained were then analyzed using One Way Analysis of Variance and post hoc. The results of the study showed that the formulation and preparation of hand washing soap with a concentration of 40% active ingredient in a solution of butterfly pea flower was able to stop the growth of both bacteria with a P value <0.05. In conclusion, these two bacteria can be inhibited with hand washing soap containing 40% of a decoction of butterfly pea flower kombucha
