In this study, the impact of power hand tools on users was considered. Five basic power hand tools were identified and the impact of vibration was assessed on users. Digital vibration meter was used to measure the vibration produced on five operators while operating the identified power tools. Values obtained from each operator were imputed to the hand-arm vibration calculator to determine daily exposure limit and total exposure point for each of them.

Doctor thesis, Universitas Brawijaya. Penelitian ini dilakukan dengan tujuan untuk m engevaluasi nilai nutrisi rumput Benggala teramoniasi RBA dengan urea dan ampas sagu terfermentasi ASF dengan Pleurotus ostreatus dalam pakan komplit sebagai pakan ruminansia terhadap penampilan kambing Kacang. Penelitian ini dilaksanakan dalam 2 tahap. Penelitian t ahap I terdiri dari 2 percobaan.
Penelitian Tahap I. Penelitian ini menggunakan RAL 4 perlakuan dengan 3 ulangan. Penelitian Tahap 2 terdiri dari 2 percobaan. Penelitian Tahap II. Nilai nutrisi RBA terbaik pada penelitian I. Penelitian T ahap II. Desain yang digunakan adalahRAK dengan 4 kelompok kambing Kacang berdasarkan bobot badan 11,6 — 15,0 kg dan 5 perlakuan pakan komplit seperti pada perlakuan Tahap II.
Hasil penelitian Tahap I. Peningkatan nilai nutrisi tersebut disebabkan oleh kenaikan PK dan penurunan kandungan lignin. Research was applied in two phases.
Phase 1 consisted of two trials. Trial 1 of phase 1 was done to obtain the best nutrient value of ABG with the optimal combination between urea level and incubation time. Factorial design with 4x4 based on the Completely Randomized Design was applied in this study.
Factor 1 was urea levels of 0, 2, 4, and 6 percents and factor 2 was incubation times of 0, 7, 14, and 21 days with four replications in each treatment. Trial 2 of phase 1 was done to obtain the best nutrient value of fermented sago pulp using Pleurotus ostreatus with different incubation times of 0, 20, 25, and 30 days.
This trial used Completely Randomized Design four treatments and three replication of each treatment. Phase 2 consisted also of two trials. Randomized Block Design RBD was applied using five treatments of complete ration and four replications for each treatment. Variables observed were pH, total gas production, NH3 concentration, VFA concentration, efficiency of micro-organism protein synthesis EMPS , and digestibility of dried matter and organic matter.
Results of trial 1 in phase 1 showed that the best ABG used in complete ration was combination of the urea level of 6 percent with incubation time of 21 hours. Improvement of this nutrition values was caused by the increasing of CP and declining of lignin content.
Results of trial 2 in phase 1 showed that the best FSP were obtained the fermented treatment using fungus Pleurotus ostreatus with incubation time of 30 days. However, these treatments did not significantly affect the pH.
The pH value in range of 6. Treatments of the complete ration using proportion of ABG and FSP did not significantly affect the total gas production under incubation of 96 hours. Total gas production tended to increase following the increase of FSP proportion in complete ration up to complete ration of P25 The highest increase of NH3 concentration occurred on the P25 treatment of The use of P25 complete ration produced the highest concentration of total VFA The P25 complete ration showed the best result based on the digested value and fermentation product of ruminants.

Trichoderma harzianum has been widely known as biological control agents of plant diseases. To obtain inoculum in large quantities waste agricultural products could be used as media. Ela sago is solid wastes originated from sago processing, contains C-organic, nitrogen, phosphorus, potassium, calcium, magnesium, as well as crude protein, fat, crude fiber, ash, cellulose, hemicellulose, lignin, and silica. The objective of this laboatory experiment was to determina the capacity of ela sagu in combination with rice bran and husks as T. The experiment was conducted from March to April The experiment was set up by using a completely randomized design, replicated three times. User Username Password Remember me.
