Abstract

The study objectives is to determine seedling growth of Gods Crown in polybag. The study design was Randomized Block Design with 6 (six) treatments and 4 (four) replications. Treatment used M0 (control), M1 (1:1:1 (soil:sand:chicken manure), M2 (1:1:2), M3 (1:2:1), M4 (2:1:1), and    M5 (2:1:2). The result of research showed that the M2 (1:1:2 (soil:sand:chicken manure) is tangible effect on plant height and number of leaves, but not give the effect to diameter stem, wet weight     of the canopy, dry weight of the canopy, wet weight of root, dry weight of root and ratio dry of    the canopy and root. Treatment M2 with composition (1:1:2) give the best result at this research. Key Words: Gods Crown (Phaleria macrocarpa L), growth, media growing composition.

Abstract

This study aims to determine the intensity of the disease Vascular Streak Dieback (VSD) in some cocoa clones in the village of the District III Sidondo Sigi Biromaru. This study was conducted in cocoa plantations in the village of the District III Sidondo Sigi Biromaru 01 ° 06 01.9 "latitude and 199 ° 54 56,0 BT 61 M above sea level. The study took place in the third week of February 2015 until the second week of April 2015. In this study used six types of clones observed that cocoa Local, S2 clone, M01 clone, Phanter clone, ICCRI 1 clone and Irian  clone. This study used survey methods and in the determination of the observation plots using Priposive Sampling method in which each set of 15 plants cocoa clones to be observed. Based on observations VSD disease in cacao plantations in the village of Sidondo III shows that the six types of cocoa clones observed have experienced any symptoms of infection VSD. From the intensity calculation data VSD disease attacks on each clone kakaodi Sidondo village III shows the percentages of different clones S2 is on average 3.53%, 4.02% Irian clones, ICCRI 1 4.43%, 4.575 M01 clones, clones Phanter 4.65% and 15.16% local cocoa. Based on the results of the calculation of the rate of fungus infection O. theobromae on cocoa clones 6 In the village Sidondo III shows the rate of infection is quite low at Cocoa Locale 0, 1307 cm², S2 0, 2195 cm², M01 0, 2207 cm², Phanter 0, 1652 cm², ICCRI 1 0, 1 348 cm² and Irian 0, 2887 cm².

Abstract

This study aims to determine the effect of various concentration of CMC of physical characteristics, chemical and organoleptic of dodol dried fruit made from sugar apple and to obtain an optimal CMC concetration on physical characteristics, chemical and organoleptic of the product by preference of panelists. This research was conducted at the Laboratory of Agricultural Technology, Faculty of Agriculture, Tadulako University, Palu on February to April 2015.  This study used a CRD (completely randomized design) for quality analysis of physical and chemical treatment which consists of 4 levels, namely the concentration of CMC 1% 2% 3% and 4%.  As for the test organoleptic properties using a Randomized Block Design (RBD).  The  result showed that the consentration of CMC did not affect the oil holding capasity, water content, and total fiber, while the solubility analysis, the water holding capasity and vitamin C showed that the concentration of CMC significantly affect the texture, color, and flavor.  Based on the analisys concluded that the higher the connsentration of CMC, the higher the quality of the product particularly the preference level of the flavor and color.

Abstract

Erosion is one of the factors that causing the decline in soil capacity to support good agriculture production. This often happened in some land use when the land is managed without pay attention to soil conservation and or the soil capacity to support production. Soil erosion prediction can be good information for local government and soil erosion index of several land use types including non-agriculture can be used to manage sustainability of development. The purpose of this study was to predict the soil erosion rate and determine soil erosion erosion index on several land use types at the Labuan Toposo village Donggala District. The soil was analyzed at soil science laboratory of Tadulako University. The study was conducted from October to January 2016. This study was used the method direct survey in the field and continued with the soil sampling for laboratory analysis. Then the analysis result was further processed by using the equation USLE (Universal Soil Loss Equation ). This study showed that the erosion index that occurredat the village of Labuan Toposo was diverse while the erosion hazard index was lowest for forest land, and the highest was found for teak and coconut. This was caused by land use patterns, land management measures, in addition the high erosion hazard index indicate the potential to cause erosion. It is therefore vital to do conservation measures to prevent erosion e.g. by inter cropping and the use of crop residue on land surface such as mulching.Key Words : Erosion Prediction, Land Use and Village Labuan Toposo.

Abstract

This study aimed to determine the characteristics of the soil under forest land, dry land, degraded land, shifting cultivation, mixed plantation, and house yards in Beka Village, Marawola Sub District of Sigi District. Three sites from each land use were determined where three soil samples were taken from each site at 0–20 cm depth using soil rings. Parameters observed included soil permeability, bulk density, porosity, water content at saturated and field capacity condition, and upper and lower plasticity limits. The soil permeability ranged from less to very fast while the soil bulk density from light to heavy. The saturated water contents were found to be 40.35% to 53.00% while the field capacity water content to be 20.18% to 26.50%. The upper and lower plasticity limits ranged from moderate to high. Key Words : Beka village, land use, and soil physical characteristic.
