Abstract

Along with growth of density of traffic getting through joint streets of Ngadirojo Biting so government of Province Central Java of has a plan to  innovate Bridge of Mider III . This Matter because of the Bridge have passed plan and also Wonogiri is area which is expanding and the position of strategic that is connecting Sub-Province of Wonogiri Central Java with Sub-Province of Ponorogo Java East. Replacment of Mider III Bridge to be build  this is prestressed-concrete Bridge with length 50 meters. This bridge consist of two unfolding limited by one pillar and two abutment. The width of bridge is  9,7  m that  consists of 2 traffic lanes, 3,5 m width of each lane and there are pavement 1  m width in the right and left side of the bridge. For upper structure, there are reinforced concrete for floor bridge, and the girders uses 10 prestreesed concrete type I height (H) 1600 mm. For under structure consists of reinforced concrete abutment with contrafort, and for pillar, it is made from reinforced concrete with rectangle shape 3 m x 3 m, and for foundations its used The Foundation using the  sinks foundation with diameter 3,5 m  for abutment and 5 m  for pillar , the depth of the  sinks  foundation for abutment is 5 m  and the depth of the  sinks  foundation for pillar  is 7 m. On the design of this bridge,Mider III is planned also connection way between bridge and ring road way which is called oprit are also designed. Each way has length 125 m and it is same on Wonogiri destination and Ponorogo  destination. This connection way uses flexible pavement with laston thick 100 mm, base course foundation with class A aggregate thick  200 mm, upper course foundation with sirtu class B thick  400 mm. Based on the bill of quantity the design of Tambakboyo bridge needs Rp 5.063.827.000,00 (Five Billion Sixty Three Million Eight Hundreds twenty seven Thousand rupiah ) and PPN 10 % Rp 506.382.700,00 (Five Hundreds Six Million Three Hundred eighty two Thousands Seven Hundred Rupiah). While this project can be finished on 34 weeks.

Abstract

Padi (Oryza sativa L.) merupakan tanaman pangan sumber utama untuk memenuhi kebutuhan nutrisi dalam tubuh. Terdapat beberapa kendala yang mengganggu pada budidaya tanaman padi, salah satu diantaranya adalah keong emas. Tujuan penelitian ini untuk mempelajari pengaruh varietas padi terhadap daya rusak keong emas pada tanaman padi, mempelajari pengaruh jenis kelamin keong emas terhadap daya rusaknya pada tanaman padi, dan mempelajari pengaruh interaksi varietas dan jenis kelamin keong emas terhadap daya rusaknya pada tanaman padi. Penelitian ini dilakukan di Laboratorium Proteksi TanamanGadingrejo, Kabupaten Pringsewu. Bahan yang digunakan adalah keong emas jantan, keong emas betina, varietas Ciherang, dan varietas lokal (padi ketan putih). Percobaan menggunakan rancangan acak kelompok faktorial (2 x 4). Faktor pertama adalah varietas padi terdiri atas varietas Ciherang dan lokal. Faktor kedua adalah jenis kelamin keong emas terdiri atas tanpa keong emas, dua ekor keong emas jantan, dua ekor keong emas betina, dan keong emas jantan dan betina yang diulangsebanyak 3 kali. Data penelitian dianalisis dengan sidik ragam dan dilanjutkan dengan uji Beda Nyata Terkecil (BNT) pada taraf 5%. Hasil penelitian menunjukkan bahwa (1) varietas padi tidak berpengaruh terhadap daya rusak keong emas pada tanaman padi, (2) perbedaan jenis kelamin keong emas jantan dan betina tidak menyebabkan perbedaan intensitas kerusakan tanaman padi, dan intensitas kerusakan yang terjadi sebesar 84,17%, (3) tidak ada interaksi antara varietas padi dan jenis kelamin keong emas terhadap daya rusaknya pada tanaman padi.
