Perancangan pembangkit listrik tenaga kincir air ini dilaksanakan dengan memanfaatkan potensi sumber daya air yang terdapat pada aliran air Coban Sewu di Desa Bendosari Kecamatan Pujon Kabupaten Malang. Tujuan dari kegiatan perancangan ini adalah untuk mengetahui kapasitas daya pembangkitan berdasar potensi hidro yang ada di lokasi, menemukan konstruksi bangunan saluran air yang sesuai, serta membandingkan antara kapasitas daya teoritis dan kenyataan di lapangan, setelah pembangkit selesai dibangun. Perancangan didasarkan pada asumsi debit andalan sebesar 0,3 m3/s. Sedangkan penentuan tinggi jatuh air, menggunakan meode water-filled tube dan diperoleh angka sebesar 3,4 m. Konstruksi PLTMH kincir air tentu terdiri atas saluran air yang dilengkapi dengan 2 pintu air, 2 buah saluran pembuang, bendungan, talang air, power house, peralatan mekanik seperti: poros, pasak, dan bantalan, sistem transmisi yang merupakan kombinasi gardan mobil, gardan truk, serta pulley dan sabuk untuk mempercepat putaran, dan satu unit generator sinkron 1 fasa. Setelah pembangkit listrik ini selesai dibangun dan dilakukan pengujian diperoleh kapasitas daya pembangkitan sebesar 3,214 kW pada putaran 17,41 rpm.. Angka ini tidak jauh berbeda jika dibandingan dengan daya teoritis pada perancangan yang sebesar 3,354 kW. Sehingga secara keseluruhan dapat disimpulkan bahwa pembangkit listrik ini bekerja sesuai dengan hasil yang diharapkan pada perancangan.

Endophytes can produce large quantities of bioactive metabolites, which are involved in the relationship between endophytes and hosts. Among the potential antagonistic bacteria that can be used as biological controllers are endophytic bacteria, namely bacteria that live in plant tissues and can move between tissues. One alternative to controlling diseases in citrus plants is to use biological agents that are antagonistic to the cause of the disease. Exploration of biological agents was carried out by isolating endophytic bacteria leaves of Madura varieties. The aim of researh was to determine the diversity index of endophytic bacteria from the leaves of Madura variety and to know the antagonistic colonies of endophytic bacteria toward Diplodia sp. The study used descriptive and experimental methods with taking into account the research objectives. Observations were carried out using PCA (Plate Count Agar) media, NA (Nutrient Agar), and MCA (Mac Conkey Agar). Diversity index of endophytic bacterial microorganisms isolated from the leaves of Madura varieties, namely 9 types of bacterial colonies obtained E1 milky white, E2 milky white, E3 milky white, E4 milky white, E5 white, E6 white, E6 white, E7 white, E8 Yellow and E9 clear white. After the antagonistic test of the nature of the bacterial colonies with the diplodia fungus sp, there were four types of antagonistic endophytic bacteria colonies namely E3 percentage (47.5%), E4 percentage (35.31%), E6 percentage (35%), lastly E9 percentage (63, 43%). Keywords: Endophytic bacteria, orange leaves, diplodia fungus. ABSTRAK Endofit dapat menghasilkan bioaktif metabolit dalam jumlah banyak, yang terlibat didalam hubungan antara endofit dan inang. Diantara bakteri potensial antagonis yang dapat digunakan sebagai pengendali hayati adalah bakteri endofit yaitu bakteri yang hidup didalam jaringan tanaman dan dapat berpindah antar jaringan. Salah satu alternatif pengendalian penyakit pada tanaman jeruk adalah menggunaan agen hayati yang bersifat antagonis terhadap penyebab penyakit. Eksplorasi agen hayati dilakukan dengan mengisolasi bakteri endofit daun tanaman jeruk keprok varietas Madura. Tujuan penelitian adalah menentukan indeks keragaman mikroorganisme bakteri endofit daun jeruk keprok varietas Madura dan mempelajari sifat Antagonis koloni bakteri Endofit kepada jamur Diplodia sp. Penelitian menggunakan metode deskrptif dan eksperimental dengan dengan mempertimbangkan tujuan penelitian. Pengamatan dilakukan dengan mengunakan media PCA (Plate Count Agar), NA (Nutrient Agar), dan MCA (Mac Conkey Agar). Indeks keragaman mikroorganisme bakteri endofit yang diisolasi dari daun jeruk keprok varietas Madura yaitu ada 9 macam koloni bakteri yang didapat E1 warna putih susu, E2 putih susu, E3 putih susu, E4 putih susu, E5 putih, E6 putih, E7 putih, E8 Kuning dan E9 putih bening. Setelah dilakukannya uji antagonis sifat dari koloni bakteri dengan jamur diplodia sp ada empat macam koloni bakteri endofit yang bersifat antagonis yaitu E3 persentase (47,5%), E4 persentase (35,31%), E6 persentase (35%), terakhir yaitu dari E9 persentase (63,43%). Kata kunci: Bakteri Endofit, daun jeruk, jamur Diplodia sp.

Student violence is still one of the problems faced by students, parents and school parties. The lack of openness from students and the limitations of parents and school parties in monitoring student activities resulted in violent acts and threats to students are difficult to avoid. To solve these problems, an application system is needed to make students connect with their respective parents and school through their personal smartphones, so they are expected to Reduce the level of violence, especially among students. The application system will be designed to be mobile-based and the design stage will use the RAD (Rapid Application Development) method. A mobile-based application system that will be designed to utilize the panic button feature to provide notification alerts from students to parents and school parties. The resulting location of the notification alert can be monitored directly on the map (maps) that is available precisely using GPS (Global Positioning System). Kekerasan pada pelajar masih menjadi salah satu masalah yang dihadapi oleh para pelajar, orang tua dan pihak sekolah. Kurangnya keterbukaan dari pelajar dan keterbatasan orang tua serta pihak sekolah dalam melakukan pemantauan aktifitas pelajar mengakibatkan tindak kekerasan dan ancaman pada pelajar menjadi sulit untuk dihindari. Untuk menangani permasalahan tersebut, diperlukan sebuah sistem aplikasi yang membuat para pelajart erhubung dengan orang tuanya masing-masing dan pihak sekolah melalui smartphone pribadi para pelajar, orang tua dan pihak sekolah, sehingga diharapkan dapat mengurangi tingkat kekerasan khususnya di kalangan pelajar. Sistem aplikasi yang akan dirancang berbasis mobile dan pada tahap perancangannya akan menggunakan metode RAD (Rapid Application Development). Sistem aplikasi berbasis mobile yang akan dirancang memanfaatkan fitur panic button untuk memberikan alert notification dari siswa ke orang tua dan pihak sekolah. Hasil lokasi dari alert notification tersebut dapat dipantau langsung pada peta (maps) yang tersedia secara presisi menggunakan GPS (Global Positioning System).

Javan langur population has decreased, because the natural habitat of Javan langurs is decreasing from year to year, in addition to the rampant fishing of langur for trading. In order to suppress and reduce the habitat destruction of these wild animals, an effective and sustainable land rehabilitation effort is needed by recording the types of forage plants that Javan langurs like and the behavior of Javan langurs in foraging for their food. One of the efforts made to create a natural breeding place. The purpose of this research is to determine whether there is a specific Javan langur eating behavior pattern, in addition to knowing whether there is a change in Javanese langur eating behavior towards the type of food given. This observation uses the Continuous Recording method of recording. The results obtained will be processed in a qualitative descriptive form (narrative). From the results of this study, it was found that there was a specific feeding behavior for each type of feed given based on the size of the leaves, when consuming calliandra with smaller leaves the langurs did not need to pick the leaves first, it was different when langurs ate mountain amethyst and telasih which were larger in size so they tended to picking and tearing it first to get smaller leaf size, and there is a change in the diet of the type of feed given, namely langurs tend to fight more for calliandra plants because calliandra has fruit as well as flowers and also smaller leaf size making it easier for langurs to eat it . This is also shown by the higher number of chews on calliandra, which is 25 chews for 10 seconds.
