Abstract

Sago is a source of staple food for the people in the eastern part of Indonesia as it contains high carbohydrate.  Many types of traditional foods use sago as their raw material.This leads to sago being utilized as alternative food besides rice, corn and tubers to support the national food security. The utilization of sago for making traditional foods can potentially increase income of the people in general.  Advance in food technology has allowed the creation of delicious and nutritious food from sago processing.  The purpose of this study were to (1) determine the income derived from the business of traditional food made from sago, and (2) analyze the revenue contribution generated from the traditional food made from sago on household income of sago farmers.  Samples were selected purposively with the number of respondents was 10 sago farmers in Alindau village.  Data collected was through observations and interviews using questionnaires.  Quantitative descriptive techniques such as income and contribution analysis were used to analyze the data.  Alindau village is one of the villages in Donggala which still has sago palm plants.  The processing of sago starch is still done traditionally using a grated coconut.  The sago farm in Alindau village has not yet currently become the main source of income for the farmer families due to increasing illegal pruning of the plant leaves which then used for forage or sold leading to badly plant growth. The income generated from the sago farming was IDR 865,000.00 in average. However, as sago is only sold in the form of flour and no further processing has been done yet, there is no contribution coming from revenue generated from the processed sago, thus, the second purpose of this study was not achieved.Keywords: Income, Sago and Traditional Food.

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

Orange is one of important agricultural commodities with highest position in agroindustry sectors; therefore it is needed a considerable effort to develop the orange plants in a large scale.  One of technologies supporting such effort is plant propagation via tissue culture technique. The aim of this experiment was to obtain the most suitable type and concentration of cytokinins for the growth of orange. This experiment was conducted in Plant Biotechnology Laboratory, Faculty of Agriculture, Tadulako University from June to November 2014.  This experiment used a Completely Randomized Design with six treatments, namely 0.5 ppm BAP, 1.0 ppm BAP, 1.5 ppm BAP, 0.5 ppm Kinetin, 1.0 ppm Kinetin and 1.5 ppm Kinetin.  Data was analyzed using analysis of variance and differences between means of the treatments were determined by Honestly Significant Difference test at 5% level.  Results of this experiment indicated that the most suitable type and concentration of cytokinin for the growth of orange was the medium culture supplemented with 1.0 ppm BAP. In such medium composition, the quickest and the highest number of shoot formation was obtained as well as the highest number of leaf formation at 6 weeks after culture, namely 3.40 days after culture, 2.12 shoots and 5.00 leaves per explant, respectively. Keywords :  Cytokinin, In Vitro,Orange.

Abstract

One of the common insects that attack tomato plant is whitefly (Bemisiatabaci Genn.). One of those classified as entomopatogen is Verticillium lecanii. The purpose of this study was to determine the effect of V. lecaniispore density on B. tabaci mortality in tomato plants. The study was conducted from January to April 2017 and located in a screening house belonging to the Department of Plant Pest and Disease and Plant Pest and Disease Laboratory, Faculty of Agriculture, Tadulako University. This study used a randomized block design consisting of five treatments including control with three replications so that there are 15 experimental units. The spore density ofV. lecanii consisted of five levels i.e. control (without treatment, p0), 10-3 Spores ml-1 (p1), 10-6 Spores ml-1 (p2),10-9 Spores ml-1(p3) and 10-12 Spores ml-1 (p4). Based on the results of the study, 10-3Spores ml-1 was the spore density that caused the highest mortality of B. tabaci with the mortality of 96.67% within eight days after the application, so the use of V. lecanii was quite effective as a bioinsecticide in controlling imago B. tabaci.

Abstract

The Objective of the study was to identify microhabitat characteristics in natural nesting ground as a basic form of egg hatching of maleo birds for ex-situ habitat in Lore Lindu National Park. Survey methods and experimental design were applied in this study using Saluki Nesting Ground as a habitat model. In a natural habitat, variables observed were microclimate condition (temperature and humidity, depth and diameter of holes) while in an artificial habitat where four different forms of eggs hatching (in-situ, ex-situ, incubator by means of media rack and sand) were applied temperature, humidity, hatching quality, incubation time, hatching weigh, and mortality were determined. Data analysis applied was descriptive analysis and multivariate test using SPSS computer program. Results of the study showed that in the natural nesting ground the temperature ranged from 30 to 35 oC with an average temperature of 33.03oC, and the humidity from 60.20 to 71.10% with an average humidity of 68.55%. The hole diameter ranged from 28-63 cm with an average hole diameter of 41.64 cm and the hole depth from 51-87cm with an average hole depth of 63.29 cm. The application of hatching method was resulted in the in-situ temperature and humidity of 32.90 oC and 68.41%, respectively, and the ex-situ of 31.68 oC and 67.52%, respectively, rack incubator of 33.99 oC and 70.06%, respectively, and sand incubator of 33.78 oC and 71.02%, respectively. The longest incubation time was found in the ex-situ semi natural hatchery which was 78.40 days, followed by the in-situ habitat 63.48 days, rack incubator 59.40 days, and sand incubator 59.33 days. The best hatching quality was found in the rack incubator, but the mortality rate was highest. The application of incubator for egg hatching of maleo birds could reduce the incubation time length and increase the hatching quality

Abstract

Utilization of arbuscular mycorrhizal fungi (AMF) is aimed at increasing crop productivityon marginal soils.AMF role as natural microorganisms areenhancing the absorption of nutrient, especially P,helping the plant to be able to withstand drought conditions as their hyphae are able to penetrate soil pores thus expanding the areas of water absorption, and protecting plant roots against pathogen attacks. Intensive planting would disturb the populationand development of the AMF. The purpose of this study was to observe the status of AMF sporeson maize (Zea mays L.).This study used a randomized block design (RAK) with 6 treatments and 5 replicates so that there were 30 experimental units.Factors studiedare several types of AMF based on the color of the corn plant area.Data fromthe study concluded that observationof AMFspores horizontally (H1, H2, and H3) showed no difference in the density of spores. In contrast, the treatment of vertical AMF(V1, V2, and V3) decreases the number of spores with increasing soil depth.  The diversity ofcolorbased AMF spores morphological types showed that there are four groups of colors i.e.yellow, brown , black, and translucent.In the Horizontal position, most AMF spores from left to right are black, while in the vertical position the dominant color is yellow.  The natural spore density in the rhizosphere of maize(Zea mays L.)generally ranges from 35 – 124 spores/10 g soil. Keywords : Arbuscularmycorrhizal fungi (AMF ), and maize.

Abstract

Research of analysis of soil fertility levels using Biochemical Index was conducted on Entisol. The soil were treated with various doses of organic matters and incubated for different periods of time in a completely randomized design. The doses of organic matter were: (i) B0 (without organic matter), (ii) B1 (10 t ha-1), (iii) B2 (20 t ha-1), (iii) B3 (30 t ha-1), and (iv) B4 (40 t ha-1). The periods of incubation were 4 and 6 weeks. It was found that increased organic levels and incubation periods could improved soil fertility with the range of the biochemical index of 4-5. The addition of organic matter increased soil pH from 6,32 to 6,68 compared to no organic matter application. The availability of phosphrous increase from 14,21 ppm to 19,88 ppm as the incubation period was increased to 6 weeks. Either in 4 or 6 week periods of incubation treatments, the C-organic contents in soils treated with organic matter were significantly higher which were 0,69 and 0,82 g kg-1, respectively, as compared with control treatment.Keywords : Biochemical index, soil fertility
