Abstract

The study was aimed at investigating the interacting effects of  Trichoderma sp. dosage and fermentation period on nutrient contents of cocoa pod. The work was carried out in Animal Feed and Nutrition Laboratory, Department of Animal Husbandry, University of  Tadulako. The first factor was Trichoderma sp dosage (2 levels) while the second factor was period of fermentation (3 levels). Analysis of variance showed that there was no interacting effect between the two factors on all parameters observed, but there were significant effects of each of individual main factor. Period of fermentation affected dry matter, crude fibre and protein contents highly significantly (P<0.01) and ash and crude lipid contents signficantly (P<0.05). Dosage of Trichoderma sp. used in fermentation showed a highly significant effect (P<0.01) on dry matter content only. Key words : Cocoa pod, nutrient content, fermentation , ruminants.

Abstract

The aim of the research was to know about the morphology characters, live cycle, and behavioral of parasitoid Trichogramma spp. from Dolago. The research was conducted in May 2003 until October 2004. Spesimen got from field and observation was conducted in the laboratory.       The result indicated that the spesimen from Dolago Parigi-Moutong was Trichogramma japonicum Ashmead spesies.  The morphology characters were: male dan female was yellowish  chocolate, red eyes and black thorax. Length body of adult was 0,4 - 0,5 mm and widely head 0,17 – 0,21 mm. Antenna type of female was capitate and male was filiform. The fore wings have trichia Rs1 as much 7-10 and in the boundary of  wings growed some hairs. Long live of  pra-adult phase was  8,2 + 0,3 days, the adult phase was 1,8 + 0,7 days and the total was 10,0 + 0.8 days. The adult parasitoid emerged from host-egg by infiltrating khorion. Immediately after it out of the host-egg, the adult look for the couple and copulation as soon as he can. Pra-Oviposition activities by female to get              the compatible new host-egg. The Oviposition activities on the first day reach 15-30 times per female. On the second day, the oviposition activities remained  1-5 times or did not oviposition  at all, than the adult immediately died. Key words : Trichogramma, japonicum, parasitoid, Scirpophaga innotata, paddy.

Abstract

The addition of preservatives may result in better quality of silage.  This experiment was aimed to examine the effects of addition of preservative on dry matter and success percentage of Panicum sarmentosum silage. The preservative used were rice bran, corn bran and salt with composition of 50, 48 and 2%, respectively. The completely randomized design was employed in this experiment with 6 treatments and 3 replicates.  The treatments were addition of preservatives at concentation of 0, 7.5; 15; 22.5; 30 and 37.5% of the grass weight.  The parameters measured were dry matter content of the silage and the degree of the success of silage. The result showed that the concentation of addition of preservative influenced significantly dry matter and the percentage of the success of silage.  However, at concentation of 22.5% of the grass weight resulted in the highest dry matter and degree of success of Panicum sarmentosum silage. Date suggested that moderate concentation of the preservatives was sufficient to increase the dry matter content and the degree of success of Panicum sarmentosum silage. Key words : Dry matter, silage, Panicum sarmentosum Robx

Abstract

Soil erosion, one of the major factors causing land degradation, has been increasing every year.    It has brought about more critical land, more frequent fload on rainy season and drouht on dry season, over accumulation of sedimentation of dams and sea, all of these leading to functional lost of water facility. A research work was conducted from July to October 2002  to measure the level of soil erosion occurred in the enclave of Miu sub-catchmet in the area of the Lore Lindu Nasional Park in connection with the different land use system existing. The research results showed that the potential of land degradation was considerable in area where intensive human activities had occured. These areas encompassed included mixed plantations, shifting cultivation, shrubs and bushes. The levels of soil erosion were in the class III-IV. Attempts to reduce soil erosion rates through vegetative and soil conservation was a success as indicated by the sift of the level of soil erosion to the lowest class. Key words : Erosion, Lore-Lindu National Park

Abstract

This study was carried out at the Animal House of Animal Production Faculty, University of Padjadjaran, from 21st March to 8th May 2003.  The objective of the research was to investigate the effects of transferring the rumen liquid of goat on the ram's carcass cuality and pelvic and kidney fat percentation. The number of experimental animal used were 14 lambs with a mean age of ± 10 months and body weight range of between 13.5 and 17.0 kg.            The animals were placed in a big animal house with tile roof, wooden floor, and wooden/wire wall.  The big animal house was then divided into 14 pens with an individual size of               1.0 x 0.75m in each of which was confined an experimental animal. The diet of the animals during the experimental period was field grass having contents of 21.83% dry matter, 12.25% crude protein, and 30.25% crude fibre. The grass was offered ad libitum without concentrate addition. Data collected were analysed with t test with two treatments: DK = control rams and               DP = treatment rams (goat's rumen fluid as much as 50% of rumen wight). The results of study showed that rumen fluid transfer increased (P<0.05) the recipients carcass quality and             the pelvic and kidney fat percentation. Key words : Rumen fluid transfer, carcass cuality, pelvic and kidney.

Abstract

The purpose of  this research is to understand the concept macroeconomic policy effectiveness, fiscal policy in particular using the rate of crude palm oil (CPO) tax  in Indonesia.  The method used is classical welfare analysis (CWA) through market demand and supply analysis approach.  The results using the rate of crude palm oil (CPO) tax and the exchange rate of US dollar showed that an inreasing in the CPO tax will decrease in surpluss consumers loss.  On the other hand, a change in export tax will reduce the pruduser surpluss, while the goverment revenue will increase in line with an increase in export tax between 5% to 15%.  Never the less an icreasing in the CPO tax at from 5% to 15% will reduce a net social welfare. Key words : Policy, CPO, consumers surpluss, Producer surpluss.

Abstract

An experiment was done to study the effect of fermented cocoa pod shell flour on body weight, dry matter consumption, and feed efficiency of local sheep. The fermented flour was mixed in concentrate given to the sheep. Details of the feed ration were as follows : i) 0% fermented cocoa pod shell flour (CPSF) in concentrate + maize silage (ad-libitum), ii) 10% fermented CPSF in concentrate + maize silage (ad-libitum), iii) 20% fermented CPSF in concentrate + maize silage (ad-libitum). The was indications that the fermented CPSF concentration gave significant effect on feed efficiency (P=0,01). Higher concentration of fermented CPSF tended to be followed by higher body weight, dry matter consemption and feed efficiency. Key words : Cacao skim flour fermentation, concentrate and feed efficiency.

Abstract

A study was conducted to evaluated effect of forest convertion to agriculture land on diversity of dung beetles which play a major role in decomposition of animal dung and carcasses. Sample was collected from Lore Lindu national Park at different land use type i.e. primary forest, secondary forest, cacao plantation ad maize field. I recorded 18 species of dung beetles from all study sites. The result showed that there were a reduction of dung beetles diversity due to forest convertion. The species number of dung beetles at primary forest was two times higher than those in secondary forest and was three times higher compared to those in cacao plantation and maize field. Furthermore, species composition of dung beetles at primary forest was significantly different compared to all other land use type.Key words : Forest conversion, diversity, dung beetles, conservation
