Abstract

The microorganisms found in the forest soil are one of the factors that influence the formation of forest soil. In mountain tropical forests slow down soil formation processes as evapotranspiration decreases, chemical reactions are slower and densities of fungi and soil bacteria are fewer, whereas in lowland forests are rich in vegetation species, as well as hot and humid climate conditions. The purpose of this research is to know the population of fungi and bacteria of forest soil of mountains and lowland forest. The study was conducted from December 2017 to February 2018. This research started from field survey, determination of sampling point. Soil sampling was done on a plot with size 25 m × 25 m with a soil depth of 0-10 cm and composite soil sampling. This research uses descriptive analysis method. The results showed that the population of fungi and bacteria are different between the mountain forest (Nokilalaki) and lowland forest (Kamarora). The lowland forest soil higher of fungi (614 × 103 CFU g-1) and bacteria population (43.6 × 106 CFU g-1) then the mountain forest soil of fungi (188.8 × 103 CFU g-1) and bacteria population (7.36 × 106 CFU g-1).

Abstract

Dendrobium orchid has great potential to be developed. The problem faced in its development is the decrease of orchid productivity per square meter of cultivation area. Consequently, the less availability of orchid either in quality and quantity. Whereas, there are growth regulator substances might be used to fulfill the hormone needs of orchid to obtain optimal growth. The main constraint is how the growth regulator substance in a certain amount affected the dendrobium archid growth. The research objective is to assess the growth response of stem cuttings of Dendrobium secundum orchid in combination of concentration and application intensity of growth regulator. This research was conducted for 3 months from October to January 2018, at Orchid Green House of the Permanent Nursery of BPDAS Palu Poso, Tadulako University. The results of study showed that the best treatment was combination of NAA (1 ml) + BAP (1 ml)/liter of water applied once a week (P1), which gave the fastest shoot growth of 16.25 days and had the highest growth on the shoot height of 3.5 cm and on the leave number of 4 sheets at the age of 12 weeks after planting.

Abstract

The participation is involvement society as active that is considered as one of the key for the approach that very promise in management forest production in development forest plants program. The government have to eforts the construction forest plants either in the forest area or in area the society property, that is more emphasize for the society participation aspect in it. The research purpose to know the society participation level and the elements relation that influence the society participation for the forest production management in development forest plants program. This research is done for three month begin april until june 2016. The location of research in sigimpu village in palolo subdistrict sigi regency.The method is used in this research, used spearmank rank correlation test. The result of this research that the society participation level for planning phase in development forest plants activity is low while for implementation phase is high. The factors infivence the participation of society for the forest plant development seen by age, education level and income level. The relation between factors influence the participation of society for every phase of development of forest plants activity, that is age factor with every phase of development of forest plants is valueable positive that pointed out of the same direction system, education level is pointed out of the same direction system too. For planning and implementation phase is pointed out of the same direction system, too.

Abstract

Watutau Village is one of the villages in the Napu valley plains of Central Sulawesi, can be found stands pine breadth ± 500ha. In addition to pine stands there are also grasslands, which are located adjacent to pine stands, it attracts attention for research because it has two distinct land cover vegetations. Differences in vegetation composition of land cover can also affect the physical condition of the soil. The purpose of this study was to determine the physical condition of the soil under the stands of pine and grassland. The study was conducted from November 2017 till January 2018, located in Watutau Village, Lore Peore Sub-district, Poso District, Central Sulawesi. This research starts from field survey, location determination, soil sampling, analysis of soil sampled laboratory. Determination of location done purposive sampling by considering slope condition that is section of valley, slope and peak. Soil sampling is done at two depths 0-30cm and 30-60cm. The results showed that the soil under pine stands had dust clay soil texture and clay, granular soil structure, bulk density 1.26gr / cm3 (High) and 1.3gr / cm3 (High), porosity 50.2% (Good) and 48.6% (Less good). Permeability 2.45cm / hr (Medium) and 2.9cm / hr (Medium), soil colors yellowish red, very dark gray, gray irish, very dark grayish brown, grayish brown. While the soil conditions in the grassland area have clay soil texture, granular soil structure, Bulk density 1,34gr / cm3 (High) and 1,4gr / cm3 (Very High), 50% Porosity (Good) and 47,63% Not good), Permeability 2.14cm / hr (Medium) and 3.66cm / hr (Medium), soil colors dark grayish brown color, brown, strong brown.

Abstract

The area of pine stands 25 year old are 500 ha grow at advacent of grassland. The pine stands and grassland have different effect on chemical properties of soil. The objective of tree study are to determine the soil chemical propertie of pine stand and grassland. The research was conducted from November 2017 to January 2018, located at pine and grassland area of Watutau Village, Lore Peore Sub-district, Poso District, Central Sulawesi. Analysis of chemical properties of soil samples including pH, C-organic, N-total, P-available, K-total and CEC was conducted at the Soil Science Laboratory, Faculty of Agriculture, Tadulako University. The results showed that pine stands had soil chemical conditions at a depth of 0-30 cm lower in (C-organic, P-available, K-total, and CEC) but higher in pH and N-total than on grassland areas. The soil chemical conditions in pine stands consist of pH 4.90 acid, C-organic 0.55% very low, N-total 0.09% very low, P-available 5.26 mg / 100g very low, K-total 11 , 81 mg / 100g low, CEC 4.29 cmol (+) kg-1 is very low. While soil chemical conditions on grassland area consist of pH 4.79 acid, C-organic 1.61% low, N-total 0.08% very low, P-available 9.24 mg / 100g very low, K-total 19.45 mg / 100g average, CEC 4.76 cmol (+) kg-1 is very low.

Abstract

Soil microorganism populations are also affected by land use forms, such as agroforestry and mixed farms. The population of soil microorganisms also form an inseparable system of life from minerals and organic matter in the soil. This study aims to determine the population of fungi and soil bacteria in agroforestry and mixed garden. This research was conducted in December 2017 until January 2018. This research started from field survey, determination of soil sampling point. Soil sampling was done on plot with size 20 m × 100 m with a soil depth of 0-10 cm and composite soil sampling ie each soil sample is represented by one same land bed. This research uses descriptive analysis method, that is by interpretation of soil biology condition data obtained from the laboratory as facts describing soil conditions in the field. The results showed that the population of soil fungi and bacteria differ between agroforestry and mixed garden. The highest number of land fungi population at the mixed garden site (811 x 103 CFU g-1), whereas the lowest fungi population at the Agroforestry Land location (20.1 x 103 CFU g-1), the highest population of soil bacteria at the Mixed Garden location (10,38 x 106 CFU g-1) whereas in Agroforestry Land has the lowest total population (33.1 x 106 CFU g-1).
