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

Hidrolisis Selulosa Dari Sekam Padi (Oryza Sativa) Menjadi Glukosa Dengan Katalis Arang Tersulfonasi

Cellulose hydrolysis from rice husk (Oryza sativa) into glucose with sulfonated charcoal catalyst was conducted. The aim of this research was to determine sulfuric acid concentration and contact time on the sulfonation process of charcoal which would produce the highest glucose rendement from cellulose hydrolysis of rice husk. Sulfuric acid concentrations in this experiment were 8, 10, and 12 N with variation of contact time of 4, 6, 8, 10 and 12 hours respectively. Rice husk was delignified with NaOH 10% to produce cellulose which was hydrolyzed by sulfonated charcoal catalyst. Hydrolysis reaction with the ratio cellulose/aquadest 1:25 (w/v) was conducted in autoclave with temperature 130 oC for 3 hours. The result showed that 8 N concentration of sulfuric acid and 12 hours of contact time produced the highest glucose rendement 17,9%

Eksperimentasi Model Pembelajaran Kooperatif Tipe Group Investigation (Gi) Dan Think Pair Share (Tps) Dengan Pendekatan Saintifik Pada Materi Relasi Dan Fungsi Ditinjau Dari Kemampuan Penalaran Siswa SMP Negeri Kelas VIII Di Kabupaten Karanganyar

The objective of this research was to investigate the effect of learning model toward learning outcomes in mathematics viewed from the reasoning ability. The learning models of this research were cooperative learning model of the GI with scientific, the cooperative learning model of the TPS with scientific, and the classical learning with scientific.This research used the quasi experimental research method with the factorial design of 3 x 3. Its population was all of the students in Grade VIII of State Junior Secondary Schools of Karanganyar. The samples of the research were taken by using the stratified cluster random sampling technique. The samples consisted of 280 students. The instruments used to gather the data were test of learning outcomes in mathematics and test of reasoning ability. The proposed hypotheses of the research were tested by using the two-way analysis of variance with unbalanced cells. The results of the research were as follows. 1) The students instructed with GI with scientific had a better learning outcomes in mathematics than those instructed TPS with scientific and those instructed the classical learning with scientific. Furthermore, the students instructed TPS with scientific had a better learning outcomes in mathematics than those instructed the classical learning model with scientific. 2) The learning outcomes in mathematics of the students with the high and moderate reasoning ability had a better than that of the students with the low reasoning ability. In addition, the students with the high reasoning ability had the same learning outcomes in mathematics as the students with the moderate reasoning ability. 3) On model of the GI with scientific, the students with the high and low reasoning ability had the same learning outcomes in mathematics as the students with the moderate reasoning ability. Moreover, the students with the high reasoning ability had a better learning outcomes in mathematics than those the students with the low reasoning ability. On model of the TPS with scientific and the classical learning with scientific results in the same learning outcomes in each of reasoning ability. 4) The students with the high reasoning ability, GI with scientific and the classical learning with scientific results in the same learning outcomes in mathematics as TPS with scientific. Furthermore, GI with scientific results in a better learning outcomes in mathematics than the classical learning with scientific. The students with the moderate and low reasoning ability had the same learning outcomes in each of learning model

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
