Abstract

This study aimed to determine the effect of source and concentration of natural PGR on growth and yield of shallot Lembah Palu variety and interaction between these factors. This research was conducted from May to August 2019 in Sidera Village, Sigi Biromaru District, Sigi Regency, Central Sulawesi, and used a Randomized Block Design (RBD) with two factors and three replications. The first factor was the different sources of natural PGR (J) consisting of 2 (two) treatments: J1 (coconut water) and J2 (moringa leaf extract). The second factor was the concentration of PGR (K) consisting of 5 (five) levels: K1 (20%), K2 (40%), K3 (60%), K4 (80%), and K5 (100%). Data were analyzed using ANOVA and followed by a DMRT test 5%. The results showed that there was an interaction between the source and concentration of PGR number of tillers at age 45 DAP, the number of tubers per clump, and the fresh weight of tubers per clump. Coconut water with a concentrate of 40% was the treatment that provided the highest result. Source of PGR had a statistically significant effect on fresh and dry leaves at age 15 DAP, total fresh and dry weight at age 15 DAP, and total leaf area per plant at age 15 DAP. Coconut water was the treatment that provided the highest result. The concentration of PGR had a significant effect on fresh leaf weight and total fresh weight per plant at age 25 DAP. Concentrate 20% was the treatment that provided the best result.

Abstract

The growth of explant in culture media is affected by a number of factors, including the strength of basal media and the concentration of plant growth regulators added into culture media. Experiments were conducted in two steps; the aim of the first experiment was to obtain a suitable strength of MS medium for the growth of onion seeds and the aim of the second experiment was to obtain an appropriate BAP concentration for each strength of MS medium for the growth of seed derived onion shoots. The first experiment was designed in Completely Randomized Design (CRD) with one factor, with treatment tested namely the strength of MS medium in two levels, eg. a half strength of MS medium and full strength of MS medium. The second experiment was also designed in CRD with factorial pattern; treatments tested were the strength of MS medium as the first factor consisted of two levels, namely a half strength of MS medium and full strength of MS medium; and the concentration of BAP as the second factor which consisted of four levels, namely 1 mg/l, 2 mg/l, 3 mg/l and 4 mg/l BAP. Results of these experiments showed that a half strength of MS medium was suitable for the growth of onion seeds which was indicated by the percentage of seed germination upto 100% and the formation of leaves tended to be more intensive. Culture medium supplemented with 4 mg/l BAP was appropriate for the growth of seed derived onion shoots which was reflected by the formation of intensive leaves and roots, in average 2.58 leaves per exsplant and 8.75 root hairs per exsplant, respectively.

Abstract

The research entitled “An ethnomedicinal study of medicinal plants used against gastrointestinal complaints by Kaili Ledo Ethnic in central Sulawesi, Indonesia was undertaken from May 2019 to March 2020. The research site was located in Raranggonau, an oldest subvillage of Kailinese Ledo aimed to conserve the ethnomedicinal knowledge of Kaili Ledo ethnic in using plants for healing gastrointestinal complaints and to select candidate medicinal plants for further phytochemical and pharmacological investigation. The data indigenous knowledge of medicinal plant has been collected by using in-depth interview with prior informed consent using an open-ended questionaire. A snowball technique was performed to obtain a appropriate respondents. Descriptive statistical method was employed to analyse and summarize the ethnobotanical data on the reported medicinal plants and associated knowledge. The result showed that there were 25 plants belonging to 16 families were found to be used against gastrointestinal complaints in the studied area. Most dominant family used against gastrointestinal complaints was Lamiaceae (3 plants), followed by Poaceae, Fabaceae, Euphorbiaceae and Asteraceae (2 plants each). Solanaceae, Asparaginaceae, Araucariaceae, Rosaceae, Rubiaceae, Musaceae, Melastomataceae, Caricaceae, Basellaceae and Balsaminaceae (1 plant each).

Abstract

This study aims to determine litter production, decomposition rate and diversity of soil macrofauna in secondary forests and candlenut stands. This research was carried out by collecting litter on the littertrap for 30 days then put it on the litterbag, then observed in secondary forests and candlenut stands in Uwemanje Village, Kinovaro District, Sigi Regency, Gawalise Mountains Slope, Central Sulawesi. Macrofauna identification was carried out at the Pest Laboratory, Faculty of Agriculture, Tadulako University, Palu, from October to December 2019. Parameters observed were litter production, decomposition rate and soil macrofauna. The results showed that secondary forest litter production (2.20 tons / ha / month) was higher than candlenut stands (2.14 tons / ha / month). The rate of litter decomposition in secondary forests is classified as moderate with a percentage of 17% -19% and the decomposition rate of candlenut stands is relatively slow with a percentage of 10-12%. The diversity of soil macrofauna species in secondary forests is similar to candlenut stands. Similarity index or similarity of soil macrofauna types in secondary forests and candlenut stands is worth 75.67%.

Abstract

This research aims to find out the role of stakeholders in the development of forest park tourism and formulate a strategy to optimize the development of forest park tourism in Ngata Baru Village, Sigi Biromaru Subdistrict, Sigi District. The sample was taken through the purposive sampling technique. The data were collected through survey and interview activities with a list of questions (Questioner) then analyzed using SWOT and stakeholder analysis. The results of the research show that the role of stakeholders divided into 3 groups, namely the first group is the subject group which consists of PKL and forest farmer who have high interests, but have low influence in the development of forest park tourism, the second group is the key player group which consists of Department of Forestry, UPT TAHURA and Department of Tourism which is the most important stakeholders in developing forest park tourism, and the third group is crowd group which consists of the village government and motorcycle drivers who have a very low role in the development of forest park tourism. From the results of the SWOT analysis, the forest park tourism included in the First Quadrant on the SWOT diagram, while the alternative strategy used is SO (Strength and Opportunities), with the consideration that forest park tourism have a lot of natural potential and large to be developed, but has not been utilized optimally, for that in developing forest park tourism must create a strategy by using strength to take advantage of opportunities, namely by: a) Managing the potential of the tourism object owned ( beautiful natural panorama, cool and pristine, abundant water sources and a comfortable atmosphere of a tourist attraction) with regional autonomy which gives regional governments authority to manage the potential of their respective regions; b) Increasing security at tourist objects in order to maintain comfort and attract more visitors to come to these attractions; c) Innovating products and tourist attractions, such as providing water play facilities, viewing posts and tourist trains; and d) Maximizing the distance to tourist objects that are close to the city to facilitate the accessibility of visitors, as well as to easily attract private investment.

Abstract

One of the major problem for fishermen of Tolo Bay water in optimizing the utilization of the fish resources is the difficulty in determining potential fishing grounds. The fishing area is very much determined by the distribution of oceanographic parameters, in particular the distribution of sea surface temperature and chlorophyll-a concentration. The aim of the reaserch is to estimate the fishing ground using integrated sea surface temperature and chlorophyll-a distribution image data from Aqua-Modis Level 3 Satellite and Seades 7.2. The Reseacrh was conducted using GIS-based Remote Sensing Method and Field Survey through in situ measurement (ground check) as validation data. Satellite image data in the form of sea surface temperature distribution and cholorophyll-a were analyzed using ArgGIS 10.2 software. Recorder sea surface temperature and cholorophyll-a image data were obtained from National Institute Of Aeronautics and Space (LAPAN) as well as data from observations at 10 station. The results of research on estimating potential fishing ground in the water of Tolo Bay based on the distribution of sea surface temperature and cholorophyll-a concertractions are integrated in the fishing ground zoning in July with nine coordinate points.
