Modelterpadu Pengelolaan Daerah Aliran Sungai (DAS) Limboto

Watershed Conditions (DAS) Limboto has faced seriously problems of highly rates of erosion, sedimentation, spread of critical land, shift functions of forests and rarity quality water of river as a resutt of floods that always happen, water scarcity and the silting up of Lake Limboto. Therefore, the research has conducted as an integral part ofan effort to develop a model ofintegrated watershed management through mechanisms of payments for environment services (PES) and identify institutional forms. Through Valuation Method and Dynamic System ver.2.5 with 84 people of sample is found that preserving watershed area of Limboto will manage by integrated watershed management through the mechanisms of Payments for Environmental Services (PES) has potential to do in light of community participation and willingness to maintain the forest while maintaining the sustainability of the future of Environment and to proven society of social-and economic matters as has showed by analysis ofdynamic systems

Metode Cekaman Luruh Bulu Yang Cocok Untuk Kondisi Di Indonesia

The objective of the research is to find out the appropriate and beneficial forced molting program that suitable with the environment and the condition of the farmer in Indonesia. The research used 180 medium type chickens, strain Dekalb Warren, aged 84 weeks old. The research applied 2×2×2 factors and used complete randomized design in (CRD) 5 times replications with 4 chickens for each repeat. The first factor was water supplying and without water supply. The second factor was the duration of no feeding for 10 and 5 days. The third factor was the amount of feed given during recovery period, that was 50% and 25% of the normal consumption. So, the total of the treatment of forced molting program applied were 9 treatments. Data obtained were analysed using analysis of variance (ANOVA), orthogonal comparison test. The result obtained showed that the treatment B (without feeding for the first 10 days, having water supply, day 11 to 30 were feed 25% of normal consumption) could be increasing the average of egg production of old chicken to 68.20%, improving feed convertion, egg quality: Haugh Unit value, yolk percentage, significantly and no differences were obsesrved among treatments versus control for egg weighth, albumen percentage, eggshell thickness. The result was also showed that the Forced Molting Stress Method used in this experiment, would be giving profit of Rp 2,500,000;- per 1,000 chickens if implemented; in the contrary, if the old chickens are allow to keep laying egg without treatment, the farmer would get deficit of Rp 467,000;- per 1,000 chickens

Pengaruh Sikap Ilmiah Siswa terhadap Hasil Belajar Materi Bangun Ruang Siswa Kelas VIII SMP Negeri 3 Minasatene

Matematika adalah pelajaran yang kurang diminati oleh siswa, dalam belajar lebih banyak siswa pasif, sehingga sikap ilmiah siswa kurang berkembang, sehingga hasil belajar siswa cenderung menurun. Sehingga guru matematika selalu berusaha mengembangkan metode pembelajaran untuk meningkatkan sikap ilmiah siswa, yang berdampak pada hasil belajar siswa. Pernyataan tersebut menarik peneliti untuk mengambil isu studi kelas VIII SMP Negeri 3 Minasatene. Populasi yang diambil adalah kelas VIII SMP Negeri 3 Minasatene, dengan sampel penelitian kelas VIIIA sebanyak 27 siswa. Teknik pengumpulan data sikap ilmiah dengan menggunakan kuesioner dan lembar observasi sedangkan hasil belajar dengan menggunakan uji. Analisis data menggunakan regresi linier sederhana. Signifikansi koefisien regresi dan model regresi kelinearan didapatkan pengaruh sikap ilmiah (X) terhadap hasil belajar (Y), menurut persamaan regresi Y = 0,0109 + 0.138X. Untuk menguji koefisien signifikansi regresi yang diperoleh t hitung 5.197 diatas tabel 2.02 maka Ho ditolak yang berarti koefisien regresi signifikan. Uji kelinearan diperoleh Fhitung 26,801 di atas Ftabel 4,08, dan signifikan 0,0

The recovery of entomopathogenic nematodes from selected areas within Peninsular Malaysia

Soil sampling was conducted within Peninsular Malaysia with the aim of recovering entomopathogenic nematodes (Steinernematidae and Heterorhabditidae). Extensive sampling was performed in the Cameron Highlands, which are climatically distinct from the lowlands, and characterized by lower temperature and humidity. The major areas sampled in the lowlands were at the campus of Universiti Pertanian Malaysia (orchards and plantations), Puchong (secondary rainforest) and along the east coast of the country. Entomopathogenic nematodes were recovered using the Galleria mellonella baiting method. Nematodes were recovered from 10% of the 425 samples assayed. Identifications, using a PCR method, revealed that the 21 identified steinernematids belonged to two different genetic types and that four out of the five heterorhabditids were Heterorhabditis indicus, the remaining heterorhabditid being a new species. The nematodes are currently being screened to evaluate their biocontrol potential for use in Malaysia against foliage-feeding lepidopteran pests of crucifers
