Abstract

Boya Baliase Village is one of the peanut production centers in Marawola Sub District because its productivity has been above the average value of 1.875 t ha-1 with harvesting area of     8 ha. In connection with this, it was necessary to identify factors influencing peanut physical yield, production cost and selling price as well as to determine the rate of income generated from the peanut farming system. This studyaimed to determine the influences of production factors including land area (X1), seeds (X2), fertilizer (X3), and labor (X4) on peanut production (Y) and to identify the income rate of peanut farming systemin Boya Baliase Village, Marawola Sub District of Sigi District. The analysis of linier regression showed that the value of Fcalculated (356.709) > Ftable (4.177) at the 99% confidence level. This indicates H0rejection but H1acceptance suggesting that the independent variables i.e. land (X1), seeds (X2), fertilizer (X3), and labor (X4) simultaneously had high significant effect on peanut production (Y). Partially, land area (X1) and fertilizer (X3) had highly significant positive effect on peanut production (Y) while seed (X2), and labor (X4) had negative effect at 99% confidence level. The average production and productivity of peanut were 886.833 kg and 1003.96 kgha-1, respectively. The net income generated by the farmer in Boya Baliase Village was IDR 11.371.022 ha-1. Key Words : Income, Peanut and production factors.

Abstract

Sitophilusoryzae L. is an important insectin warehouses causing damages to rice grainsand assisting fungal growthto spreadin a short time.  This leads to the rice grain become inconsumable. Symptoms of attacksinclude holes in rice grains or the rice grains change into flour. This study aimed to determine the effectiveness of extracts of fragrant pandan leaves (Pandanus amaryllifolius Roxb.) in controlling Sitophylusoryzae L.  The research was carried out in the Laboratory of Disease of TadulakoUniversity and arranged in a completely randomized design (CRD) with five treatments and replicated five times. The treatments included control (without treatment, A0), 5% fragrant pandan leaf extract (A1), 10% fragrant pandan leaf extract (A2), 15% fragrant pandan leaf extract (A3), and 20% fragrant pandan leaf extract (A4). Data was then analyzed using analysis of variance followed by a HSD test at 5% level when the treatments had significant effect. The study showed that the leaf extract of P. Amaryllifoliussignificantlyaffected the mortality ofSitophylusoryzae L observed at oneWAA (week after application), two WAA, and three WAA. The leaf extracts of P. amaryllifoliusapplied at theconcentration of 20% is more effective in controlling Sitophylusoryzae L atone WAA, two WAA, and three WAA. The insect mortality was 57.87% at the concentration of 20% while it was 50.52% at the concentration of 15%,30.16%at the concentration of 10%, 18.2% at the concentration of 5%, and least at Control.

Abstract

Sheep is one of the preeminent commodities of Central Sulawesi in term of natural/pastural resources, climatic and cultural social condition. All varieties of local sheep in Central Sulawesi were generated from a cross-breeding between Fat-tail sheep (FTS) and Merbas sheep. The research was aimed at identifying the sheep phenotype characteristics as the criteria for sheep selection. The study was carried out in Palu city, and Biromaru sub district of Central Sulawesi from February to May and from November to December 2006. Data of sheep body sizes were collected from three different sites: Poboya (East Palu), Kawatuna (South Palu) and Loru (Biromaru). A total number of 412 sheep from the three sites were used and then randomly selected to obtain 102 (24%), 122 (10%), and 56 (28%) adult sheep from Poboya, Kawatuna and Loru, respectively. The research results showed that the local sheep population has been steadily decreased every year and currently there have been only 3270 sheep remained.  Among the three sites, the highest body weight of sheep was found with those from Biromaru. The average of birth weight,  weaning,  adult  males  and  females  body  were  3.25±0.53  kg,  11.25±3.33  kg,  42.00±6.245  kg,  and  30.14±6.28  kg, respectively. The body size of 18-24 month old sheep from Biromaru was also higher than those from the other sites.  Whereas for 36 month old sheep, those from  East Palu and Biromaru  were higher than those  from South Palu. The principal  Component Analysis (PCA) showed that the best criteria for sheep selection were breast diameter, body length, height of hip, and wide of tail.

Abstract

This study was conducted between January and May 2005 to explore effects of insecticides on the eggs of rice stem borer Scirpophaga insertulas Walker. This was done at the Lanrang experimental farm station and the laboratory of entomology and plant physiology of ICERI. There were four rice varieties used in he experiment (Gilirang, Cigeulis, Lok Ulo and Cibogo), each of which was observed in a 5 x 5 m observation plot.  Observation was done by collecting egg of rice stem borer on selected plant samples. The collected eggs were placed in test tubes, labeled, and brought to laboratory and the parasitoid found was examined under a light microscope. Results showed that for the four rice varieties tested, it was found three parasitoid species on S. incertulas egg i.e. Trichogramma japonicum Ashm., Telenomus rowani Gah., and Tetratichus schoenobi Ferr. Nevertheless, in one egg mass of S. incertulas, not all species of parasitoid found at the same time, sometimes T. japonicum with T. rowani, T. rowani with T. schoenobi, or T. japonicum with T. schoenobi. There was no direct effect insecticide application to parasitoid population.

Abstract

The aims of this experiment were to determine the most suitable phase of palm sugar tree for producing starch and the characteristics of starch (functional, physical and chemical compositions) which were appropriate for starch noodle. Three growth phases of palm sugar tree were observed, namely: before flowering, productive growth and post growth productive phases.  Starch characteristics analyzed included water content, reduced sugar, starch, amylase, lipid, protein, fiber, ash, acid degree, form and size of granular, and starch amilography. Starch of green bean was used as a comparison.  Results of this experiment indicated that the highest starch content on the palm sugar tree was found at the productive growth phase. The characteristics of starch on the palm sugar at the post growth productive phase were similar to the starch of green bean. Therefore, starch obtained from post growth productive phase is the best for starch noodle.

Abstract

Swamp land is a suboptimal land which is potential for the development of food crops, including rice Inpara varieties. The increase in rice yield planted in suboptimal land, suach as in swamp land is highly determined by a number of factors, including the application of a suitable fertilization package. This experiment was conducted on farmer land via on farm adaptive research (OFAR) approach using Randomized Block Design with 5 fertilization packages. Each fertilization package was repeated 5 times and therefore there were 25 plots used. Each plot was planted with 375 seeds, resulting in a total of 9,375 plants. Fertilization packages tested consisted of: d1 = Farmer's fertilization dosage (50 kg urea/ha + 50 kg phonska/ha); d2 = Fertilization dosage based on soil analysis (116 kg Urea/ha + 81 kg KCl/ha + 88 kg Phonska/ha); d3 = Fertilization dosage based on IRRI interpretation (100 kg Urea/ha + 125 kg Phonska/ha); d4 = Recommended fertilization dosage of BPP (85 kg Urea/ha + 85 kg SP-36/ha + 50 kg KCl/ha); and d5 = Fertilization dosage based on swamp soil test interpretation result (PUTR) (300 kg Urea/ha + 50 kg SP-36/ha + 150 kg KCl/ha). Results of plant height and number of tillers were obtained on the use of d3 and d5 fertilization packages of 100.5 cm and 16.1 tillers respectively. While the average number of panicles, the weight of dried grain per mill and the weight of dry grain per milled per plot was obtained on the use of d5 fertilizer package of 15.7 panicles each, 45.9 grams and 5.0 kg per plot. Keywords : Inpara rice, swamp land, fertilization package

Abstract

The research on vegetative breeding of jack fruit has been conducted through grafting method, aiming at finding out the compatibility of lower cultivar resisting to drought stress with the jack fruit entries of pre-eminent varieties originally from central Sulawesi. Generally, the results of the research indicated that all entries except those grafted with the root stock BK-3 and TL-5 could only survive for 2 weeks leaving only their dead scions.  The latter appeared to be compatible with the Palupi entries as they were still able to live and grew until this research ended

Abstract

The fish growth is influenced by the quality of food consumed. EM4 with difference doses (0, 5, 10, and 15 ml/kg diet) was carried out to investigate feed efficiency and the growth of nila gift. An experimental method based on completely randomized design in four replicates was used for 35 days. nila gifts with 12 – 18 g in body weight were used. Fishes were fed twice daily as much as 5% of their body weight and unfed one was taken an hour after feeding. The result showed that the differences of EM4 on diet did not affect feed efficiency and the growth of nila gift. However, EM4 suplementation on diet could increase its protein content.
