Abstract

Predator Dolichoderus thoracicus is a highly potential and has sound prospect in the future as biological control agent against cocoa pod borer (CPB), Conopomorpha cramerella because D. thoracicus function as a predator on cocoa plantation.   This research aimed to determine: (a) effective technique of the predator D. thoracicus application in artificial nest established at people cocoa plantation, (b) level of cocoa bean damage, (c) distribution pattern of D. thoracicus, (d) cocoa production analysis result. Research consisted of several phases including setting up artificial nest in cocoa plantation, recording data of cocoa pod borer attack level and analysing the cocoa production.  Results showed that exploiting D. thoracic us could reduce the CPB attack by 8.28%, lower the percentage of bean damage by 25.36%, and reduce the loss of cacao bean weight by 16.14%

Abstract

The study was done at fishery catching area in Ampana Kota district on April to September 2009. This study was aimed to observe the income level of fishery households and social economics factors that influence delivery and receiving of fishery credit at Ampana Kota district. The research used a survey method. The research results showed that the income level of fishery catching was IDR 8,192,450 per household per year. Credit aid programs can be used as a mean to improve the contribution of fishery sector. The credit delivery and receiving were influenced by age, education level, production and household income.

Abstract

High content of aluminum and low N availability in Ultisol are the important limiting factors for crop production. Hence, important efforts on management of Ultisol are increasing N availability for crop demand. Guano fertilizer and pruning of Lamtoro are source of organic matter used to improve the soil, although the two fertilizers still not yet have full attention. The present study was aimed to elucidate roles of Guano fertilizer and green manure of Lamtoro on Al concentration, N availability, crop growth and N uptake by maize in an Ultisol.  The study was conducted in a glasshouse. Combination of the two fertilizers at two different rates of each fertilizer (10 and 20 ton/ha) and one control (no fertilizer added) resulted in nine treatments and they were arranged in a factorial randomized block design with three replicates. Results of the experiment showed that the application of Guano fertilizer and Lamtoro green manure significantly reduced Alexch concentration, increased soil pH, increased N availability, improved maize growth and increased N taken up by maize grown for 45 days.

Abstract

A research was performed to study production and nutrient composition of forage produced from a natural grassland in Lore Utara Subdistrict, Poso District. Forage samples were collected from two villages (Winowanga and Alitupu) with a destructive sampling method using a pair of 1 m2 sized quadrant. These samples were then taken to University of Tadulako for dry matter and main nutrient analysis at the Animal Nutrition Laboratory, Animal Science Department. On the basis of dry matter contents, the available dry matter production and carrying capacity were calculated with some assumptions, and all data were descriptically analysed. Results showed that the forage consisted mainly of grass with an average available dry matter production of 941 kg/ha. Average carrying capacity was 0.63 AU/ha/year, calculated assuming 1 AU is equivalent to a 500 kg cattle. Average nutrient contents (g per 100 g) were 6.47 (crude protein), 2.23 (crude fat), 42.71 (crude fibre), 9.98 (ash), and 40.29 (nitrogen free extracts).

Abstract

The research aimed to determine the quality characteristics (physical, chemical, microbiological and organoleptic) of pre-storage Palu fried onions before storage and to identify factors affecting the quality characteristics. To achieve the purpose of the study a series of activities was conducted including selection/determination of samplse, identification and analysis of physical, chemical, microbiological and organoleptic components of 10 selected samples of fried onions. The results showed the lowest value for water content (1.88%) was in the sample I, oil (30.64%) in the sample H, ALB (0.17%) in the samples B, C and G, minerals (2.51% ) in the sample F, KBC (7.99%) in the sample C, and total microbes (10 colonies / g) in the samples E and J. The most crispy texture (F max 0.12 N) was in the sample I. The highest value for the aroma score (3.33) was in the sample E, taste (3.97) in the sample D, crunchiness (4.07) and preference (3.80) in the sample B.  The highest quality characteristics of fried onions before the storage was found in the sample B and I,  followed by samples D, E, G, C, J, A, H, and F, respectively. The factors affecting the quality characteristics of Palu fried onion  before storage included (1) the level of mixed materials used was still very high, (2) continous reusing of oil, (3) uncontrollable frying temperature, (4) short time for reducing oil content, and (5) thin and not airtight packaging materials.

Abstract

The aim of the research was to identify factors affecting population and productivity of cattle and factors causing people number involved in cattle farming in Parigi-Moutong. The research used descriptive and explorative methods to analyze problems related to those factors affecting the responses of the community on cattle farming system. The results of survey and interview conducted to respondents showed that economic background and land area size were the limiting factors for the cattle farming development. The cattle farming system could not be improved as the main agribussines based on the present condition of the farming system in term of its scale, the farmers’ condition and its main goal. The responses of the community on cattle farming system were also still low particularly for the local people.

Abstract

The field experiment was conducted to study  changes in  total  nitrogen, available phosphor, available potassium and sweet corn yield (Zea mays saccharata sturt) as a result of liquid organic fertilizer addition on Entisols of Poboya.  The experiment was carried out from June to September 2007 in  Poboya  farm field of Palu. A Randomized Block Design (RBD) was used with two factorial experiment replicated three times.  The first factor was liquid organic fertilizer of four levels: 0 cc l-1; 5cc l-1; 10 cc l-1 and 15 0 cc l-1. The second factor was various time of fertilizer application: applied twice at 4 and 8 weeks after planting; and three times at 3, 6 and 9 weeks after planting. The tested plant used was sweet corn. The results of the experiment showed that liquid organic fertilizer and application time significantly improved the soil chemical characteristics of Poboya Entisols and increased the sweet corn yield. A maximum result of 3.9 ton ha -1 sweet corn was observed in 15 ccl-1 liquid fertilizer treatment with application time of 3,6, and 9 weeks after planting.
