Abstract

This study aims to determine the vegetative growth of Dendrobium sp orchids at various concentrations of liquid organic fertilizer and fertilizer intensity. This research was designed with a completely randomized design (CRD) factorial pattern. The first factor is the concentration of liquid organic fertilizer consisting of three levels, namely the concentration of 5 ml / liter (A1), 10 ml / liter (A2), 15 ml / liter (A3), and the second factor is the intensity of fertilization consisting of 1 time / week ( B1), 2 times / week (B2), 3 times / week (B3). The results showed that the interaction between the concentration of liquid organic fertilizer and fertilizer intensity significantly affected the time parameters of buds, shoot height, and number of leaves. The 10 ml / liter concentration treatment with fertilizer intensity 3 times / week (A2B3) gave the fastest shoot growth of 7.93 weeks and had the highest yield on Dendrobium sp orchid shoot height at 12 weeks after planting which was 3.5 cm and the amount Dendrobium sp orchid leaves at the end of the observation were 4.75 strands.

Abstract

Nyatoh (Palaquium obtusifolium Burck) is a type of tree that is very much in demand by local and international communities. Nyatoh stands (Palaquium obtusifolium Burck) which is adjacent to the agricultural crops owned by residents in the village, is interesting because it will show that, the level of soil fertility is influenced by vegetation. Not only that, according to local residents, after the land was planted with Nyatoh plants (Palaquium obtusifolium Burck) erosion and landslides had not occurred again.The research was conducted from October to December 2017 located in the village of Sindosa, Sindue Tobata district, Donggala district. This research was started from a field survey, determination of sampling points, soil sampling and analysis of soil samples in the laboratory of the Faculty of Agriculture, University of Tadulako. Soil sampling is done by taking intact soil samples at several predetermined locations namely peaks, backs, and valleys. Each slope is determined by 5 soil sampling points to represent each location with 2 types of depth, namely 0-30 cm and 30-60 cm. Then the samples obtained from these 5 points will be compiled. From the three locations there were 30 soil samples before they were compiled. Overall soil samples after being compiled will get 6 soil samples analyzed at the Soil Science Laboratory of the Faculty of Agriculture to determine the chemical condition of the soil. Data obtained from the laboratory are then analyzed descriptively, namely by describing the chemical properties of the soil, namely pH, CEC, C-Organic and soil organic matter.The results showed an average pH with a depth of 0-30 cm, which is 6.64, while at a depth of 30-60 cm showed a pH with an average of 6.43, Cation Exchange Capacity (CEC) on average below the Nyato stand at Sindosa village Sindue Tobata District Donggala Regency at a depth of 0-30 cm, which is 25.87 (cmol (+) kg ¹) is in the medium category, while at a depth of 30-60 cm is 3.23 (cmol (+) kg kedalaman ¹) belongs to the very low category. The C-Organic content at a depth of 0-30 cm with an average of 2.45 is included in the medium category and at a depth of 30-60 cm that is 0.65, including very low. The content of Soil Organic Materials (BOT) with an average depth of 0-30 cm, which is 4.23 included in the high category and at a depth of 30-60 cm with an average of 1.11 is low.

Abstract

Palu City is the Capital of Central Sulawesi Province, which is also the center of a variety of activities and services for both residents within the city and other areas outside or around the City. Activities and services of the population have resulted in the city of Palu experiencing very rapid development. The rapid growth of settlements and development in the city of Palu will have a significant influence on land use change. Changes in land use that are not in accordance with the rules of spatial planning can result in decreased environmental quality, environmental degradation / environmental damage and reduced natural resources. The declining quality of the environment is due to the increasingly spatial allocation of space for urban vegetation. The purpose of this study was to determine the level of air temperature distribution in Ulujadi District based on Landsat 8 imagery and determine the level of vegetation density based on air temperature. This research was conducted for 3 months from February to May 2016. Analysis of air temperature using band 11 to analyze the distribution of air temperature by comparing the vegetation density analysis of NDVI (Nomalized Difference Vegetation Index) using band 5 (NIR) and band 4 ( Red) on Landsat 8 imagery to determine the effect of vegetation absorption on air temperature by using ArcGIS software version 10.2. Based on the analysis of air temperature using Landsat 8 imagery, it can be concluded that the distribution of air temperatures in Ulujadi District ranged from 18.89 - 25.890C with an area of 1954.48 Ha (31%), 25.90 - 32.890C with an area of 2.198 , 67 Ha (35%), and the highest temperature distribution in Ulujadi District reached 2,213.83 Ha (35%) with an air temperature level of 32.90 - 39.890C. The level of vegetation density in Ulujadi Subdistrict is divided into three with a vegetation index value of -0.19 - 0.25 sparse density, with a distribution area of 1,381.79 Ha (22%), moderate density 0.25 - 0.35 medium density with the distribution area is 965.57 Ha (15%), the density of the meeting is 0.35 - 0.60 with a distribution area of 4.018.80 Ha (63%) from the area of Ulujadi Subdistrict.
