Abstract

This study was aimed to determine the abudance crown of thorn starfish (Acanthaster planci L.) in the Gulf of Tomini, Central Sulawesi. The study was conducted in February─April 2019 preliminary method used a purposive sampling (determining the sampling point for transect sampling) and the belt transect method which is 20 x 2 m. Sampling of A. planci was carried out at 4 stations. Data collected were the number of individuals, measurement of environmental parameters including Temperature, pH, Salinity, DO and Substrate observations on habitat. Based on the results of the study, 48 individuals at all stations and the abundance of A. planci in the Gulf of Tomini, Central Sulawesi were in the natural/normal category with a value of 0.01 ind/m2─0.25 ind/m2.

Abstract

Increasing plant growth by arbuscula mycorrhizal fungi depends on the fungus and plant spesies. The aim of this study was to determine the efectivity of fungal mycorrhizal fungus on the growth of cayenne pepper, tomato and eggplant which are Solanaceae family members. The study was conducted by Completely Randomized Design method.with two factors. The fisrt factor was species of experimental plant consisted of cayenne pepper (Capsicum frutescens L.), tomato (Solanum lycopersicum L.) and eggplant (Solanum melongena L.). The second factor was addition of Glomus clorum inokulum consisted of with and without inoculum addition. The result showed that there was no effect of inoculum addition on plant growth of three experiemal plants. The quality of inoculum used for this experiment was not good enough furthermore fungi could not germinate and colonize plant root.

Abstract

The study about the observation of spinach (Amaranthus tricolor L.) growth after the addition of liquid biofertilizer (active ingredient Aspergillussp.) had been conducted in Taman Pangan Gizi Langaleso Village, Dolo Subdistrict, Sigi District, Central Sulawesi, and Laboratory of Biotechnology, Biology Department, Faculty of Mathematics and Natural Sciences, Tadulako University, Palu, from March to November 2018. The aim of the study was to observe the growth of spinach after the addition liquid biofertilizer (active ingredient Aspergillus sp.) along with the fermented soybean liquid waste and coconut water waste as the main media. This study was designed using the Completely Randomized Design which consisted of 7 treatments with 5 repetitions. The treatments were arranged as follows: P0 (without the addition ofbiofertilizer, as the negative control), P1 (2.5%biofertilizer addition), P2 (5%biofertilizer addition), P3 (7.5%biofertilizer addition), P4 (10%biofertilizer addition), P5 (12.5%biofertilizer addition), P6 (NPK addition, without the addition of biofertilizer, acting as the positive control). The results showed that treatment P4 was indicated as the best growth among any other treatments as well as the control, based on the parameters of the height of the plants (10 cm), the number of leaves (8.35 leaf blades), the dry weight of biomass (1.95 g), the fresh weight of canopy (4.94), the fresh weight of leaves (2.07 g), the dry weight of leaves (0.22 g), the fresh weight of roots (2.11 g), the dry weight of roots (0.24 g) and the length of the roots (12.2 cm).

Abstract

Actinomycetes that live in the rhizosphere of the Leda plant (Eucalyptus deglupta Blume.) Have the potential to produce pathogenic antibacterial compounds in humans. The ecosystems thought to be inhabited by Actinomycetes that produce pathogenic antibacterial compounds in humans is the rhizosphere of Leda endemic plant in the Lore Lindu National Park, Central Sulawesi. The purpose of this study was to isolate various isolates of Leda plant rhizosphere Actinomycetes in TNLL as a producer of pathogenic antibacterial compounds in humans. This research is divided into several stages. The first stage was sampling, isolation, and screening of Actinomycetes producing human pathogenic antibacterial compounds. Rhizosphere soil samples were taken by purposive sampling method combined with the quadrant method by measuring various environmental factors. The second stage is a selection to analyze the potential and efficacy of Actinomycetes isolates as producing antibacterial compounds against pathogenic bacteria in humans. The results showed that the condition of Leda plant vegetation in the Anaso-Rorekatimbu area was generally the same for each spot and supported the presence of Actinomycetes. The density of Actinomycetes is relatively the same for each spot. As many as 15 isolates were isolated from the Leda rhizosphere of Actinomycetes. Based on spore morphological and biochemical characterization, the 15 isolates were included in the Genus Streptomyces. Actinomycetes isolates L213, L433, and L411 were the most potent isolates and had broad-spectrum inhibition, because they were able to inhibit the four test bacteria S. aureus, MRSA, V. cholera, and EPEC.

Abstract

Study of composition and community structure of zooplankton in Talaga Lake was conducted from February to March 2019. The aimed of this research was to know the composition and structure of zooplankton in Talaga lake, Central Sulawesi. Samples were collected at four station by using purposive sampling method. The identification results have found 4 genus of zooplankton with each composition 71 % of Cyclops, 22 % of Daphnia, 0,34 % of Paramecium and 6,64 % of Chaoborus. The zooplankton abundance is around 11.6-17.2 ind/l. Community structure of zooplankton in Talaga Lake is unstable which shows by the low value of diversity index (0.68 to 0.8) and uniformity index (0,49-0,57). The value of dominance index which is in range 0.51-0.58 has also shown that there is dominant type of zooplankton.

Abstract

The use of traps is very important in the process of sampling bats in the field. The mist net is a type of traps that commonly used to catch bats for research purposes. This study aims to determine the effectiveness of using mist nets in bats sampling. Sampling site located in the Lindu Plain, District of Sigi, Central Sulawesi. Bats were sampled by mist nets using purposive sampling method, at four different types of habitat. The result of this study indicated that mist net is effective in catching fruit-eating bats (Megachiroptera), but is not effective in capturing insectivorous bats (Microchiroptera).

Abstract

The research "Primary Productivity of Lake Sibili of Tawaeli District, Palu City, Central Sulawesi" was carried out from January to February 2019. This study aims to determine the primary productivity of waters and the physical and chemical parameters of Lake Sibili and as a first step in the use of Lake Sibili sustainable. This study was carried out using the method of oxygen light bottles and dark bottles. The results of the research have shown that station III has the highest net photosynthesis with a value of 1.875.0 mgC/m3/day (Table 2) this is caused by the temperature and pH of the station is relatively high which has an average temperature of 30.3 oC and average pH - 7.6 so that this can increase the rate of photosynthetic activity by phytoplankton while the lowest net photosynthetic value is at station I with a value of 812.4 mgC/m3/day which has a relatively lower temperature and pH compared to other stations which have an average temperature average of 28.9 oC and average pH 7. so that based on primary productivity values obtained during the study, the waters of the lake Sibili can be categorized as Eutrophic waters.
