PENDAHULUAN BAHAN DAN METODE PENELITIAN Rumput atau turfgrass merupakan salah satu tanaman yang dibudidayakan Penelitian ini dilakukan di lahan yang manusia. Rumput digunakan sebagai terletak di UPT Pengembangan Benih tanaman hias yang berada di taman atau Palawija Kecamatan Singosari Malang tempat wisata dan juga digunakan sebagai dengan ketinggian 500 mdpl, suhu rata – sarana untuk berolahraga, misalnya di rata harian 24oC dan jenis tanah Vertisoll. lapangan sepak bola, padang golf, Penelitian dilakukan pada bulan April lapangan tenis dan lain-lain. Dalam sampai Agustus 2016. Alat yang digunakan pemilihan rumput untuk lanskap, termasuk dalam penelitian ini antara lain: cangkul, untuk lapangan golf, didasarkan pada gembor, gunting rumput, penggaris, jangka berbagai pertimbangan meliputi ketahanan sorong, timbangan, oven, kuadran 10 x 10 dan kualitas hamparan dan kecepatan cm, munsell colour chart, tali raffia, papan pertumbuhan / penutupan tanah merupakan nama dan alat tulis. Bahan yang digunakan kriteria utama (Nasrullah dan Tunggalini, pada penelitian ini antara lain: 3 jenis 2000). Rumput yang biasa digunakan dalam turfgrass yaitu rumput bermuda (Cynodon pembuatan suatu lansekap ada beberapa, dactylon), rumput jepang (Zoysia japonica) antara lain rumput jepang (Zoysia japonica), dan rumput gajahan (Axonopus rumput manila (Zoysia matrella), rumput compressus), air untuk penyiraman dan gajah mini (Pennisetum purpurium), rumput pupuk anorganik (pupuk NPK). gajahan (Axonopus compressus), rumput Penelitian ini menggunakan metode bermuda (Cynodon dactylon).

Kualitas rumput rumput jepang (Zoysia japonica), rumput yang baik harus didukung dengan gajahan (Axonopus compressus). perawatan yang optimal. Salah satu Perlakuan yang digunakan adalah interval kegiatan perawatan rumput yang sangat pemangkasan yang terdiri dari 3 taraf, yaitu penting adalah pemangkasan (Suastawa et P1 = 7 hari sekali, P2 = 10 hari sekali dan al., 2003). Pemangkasan dilakukan untuk P3 = 14 hari sekali. Pengamatan dilakukan menjaga agar ketinggian dari rumput yang pada 1 MST hingga 10 MST dengan digunakan tidak mengganggu pada saat presentase penutupan. Selanjutnya rumput tersebut digunakan. Pertumbuhan dilanjutkan 12 MST – 18 MST dengan vertikal dari tanaman ini dapat menurunkan kepadatan pucuk, panjang daun dan skor kualitas, sehingga diperlukan pemangkasan warna daun. Pada 18 MST pengamatan rutin yang dapat menghabiskan biaya yang dilakukan adalah panjang akar, berat banyak untuk tenaga kerja, peralatan dan kering tajuk, berat kering akar, berat kering bahan bakar pada setiap pemangkasannya total, daya recovery dan ketahanan 1713 Hardiman dan Wicaksono, Respon 3 Jenis Turfgrass... terhadap gulma.

  • Distribution and Collecting Method of Fingerling Eeel (Anguilla Sp.) in Bengkulu Province
    International Seminar on Promoting Local Resources for Food and Health, 12-13 October, 2015, Bengkulu, Indonesia Distribution and Collecting Method of Fingerling Eeel (Anguilla Sp.) in Bengkulu Province Dede Hartono, Deddy Bakhtiar, Zamdial Ta’alidin Department of Marine Science Bengkulu University Corresponding author email: [email protected] ABSTRACT Indonesia is an archipelago that is rich in resources eels (Anguilla Sp.). There are at least six types of eel, Anguilla mormorata, Anguilla celebensis, Anguilla ancentralis, Anguilla borneensis, and Anguilla bicolor, Anguilla pacifica. The types of eels are spread in areas bordering the deep sea. Nevertheless eels are not yet widely used economically. Whereas the eels in both, the size of the seed and the size for consumption are abundant. Bengkulu Province is located at latitude 2 16 '- 3 31' and 101 1 '- 103 41' E, which is located on the western edge of the island of Sumatera. Western parts of Bengkulu province directly dealing with the Indian Ocean with a coastline of about 525 km long. In the very long coastline it flows 134 rivers and creeks. Bengkulu province occupies most of the western slopes of the Bukit Barisan Mountains. In such areas generally have rivers shorter. In accordance with the topography is hilly and steep, generally torrential streams and rafting. The condition is an ideal habitat for eels. This study aims to determine the distribution and collecting method of fingerling eels in Bengkulu water body, especially rivers, as well as knowing the environmental conditions eel habitat. The method used in the study is the survey method, by direct observation in the field.

  • Recovery Cooperation for Padang Earthquake Damage by Seismic Isolation Buildings Design
    RECOVERY COOPERATION FOR PADANG EARTHQUAKE DAMAGE BY SEISMIC ISOLATION BUILDINGS DESIGN EWBJ (Engineers without Boarder, Japan) Takayuki Teramoto Toshio Okoshi Tokyo University of Science Tokyo Polytechnic University Tokyo/ Japan Tokyo/ Japan Abstract At September 2009, the earthquake of M7.6 occurred around Padang city of Sumatra, Indonesia. Non- profit-organization EWBJ (Engineers without Border, Japan) have cooperated to research the seismic damage and have proposed for the recovery and strengthening of damaged governmental buildings by the financial support of Japan Platform. After these, local government of South-Sumatra decided to construct new governmental buildings by the seismic isolation technique and requested to cooperate for EWBJ. EWBJ has cooperated for two seismic isolation building projects with Andalas university engineers of Padang. And two governmental buildings are now under construction. 1 Time-history of the Cooperation (1) Sep. 2009 Padang earthquake occurred. (2) Oct. 2009 1st cooperation of earthquake damage research Earthquake damage s were researched by the association team of EWBJ (Engineers without Boarder, Japan), JSCE (Japan Society of Civil Engineers), JSAEE (Japan Association for Earthquake Engineering). (3) Dec. 2009 2nd cooperation of earthquake damage recovery EWBJ members of architectural team (Teramoto & Okoshi) and civil team visited Padang for the cooperation of earthquake damage recovery. Finally two symposiums were held at Padang and Jakarta (4) Apr. 2010 3rd cooperation for earthquake damage recovery EWBJ architectural team held a symposium at Padang about the design techniques of seismic isolation buildings. At the end of this visit, EWBJ was requested the design cooperation of five seismic isolation buildings by local government. EWBJ agreed to this and the seismic isolation design cooperation project was started from this time.

We conducted a field survey from October 2015 to January 2016 at two different sites: Gunung Meru (GM) and Gu- nung Padang (GP), where macaques receive high and low provisioning, respectively. The time budgets of macaques significantly differed between study groups. At GM, ma- caques spent more time resting, feeding, acting out agonistic behaviors, and less time moving and searching for food, than the macaques at GP. Diurnal activity patterns sig- nificantly changed within a day. The short-term change in activity of the macaques was closely related to the number of tourists: they spent a greater time feeding and search- ing when more tourists came to feed the monkeys, while time for grooming decreased. Our result showed that the ability of the macaques to adjust their activity in response to the number of tourists (that is, provisioning patterns) indicated their behavioral flexibil- ity.
