Abstract

Sidenreng Rappang Regency is the center for developing rice production in South Sulawesi and is included in the Bila River Basin (DAS). Sidenreng Rappang, in the last five years, has experienced flooding every year, especially in Pitu Riawa District, Dua Pitue District, and Pitu Riase District. This study aims to project rainfall changes and vulnerability to flooding based on the HadCM3 climate model in the Bila watershed area. Analysis of changes in rainfall based on the HadCM3 climate prediction model with a short-term baseline (10 years). Data were analyzed spatially by scoring the parameters of flood vulnerability and validated through surveys and field observations. Data for each parameter is overlaid using a geographic information system (GIS). The actual flood vulnerability classification results were projected using the HadCM3 climate model and produced a flood hazard projection map with the HadCM3 model for the Bila watershed area. The HadCM3 model prediction shows an increase in rainfall from April to October, and high-intensity precipitation occurs in May, June, and July. The actual level of flood hazard in paddy fields in the Bila watershed area is classified as very high, with an area of 22,339.44 ha (56.75%), and the HadCM3 Climate Model projection is classified as high with an area of 25,260.71 ha (64.17%). Paddy fields in the Bila watershed have a high level of flood vulnerability.

Abstract

One of the agricultural development goals is to develop farming businesses that spur economic activity, create jobs and improve people's welfare. The research was conducted in Barugae Village, Mallawa District, Maros Regency. The location selection was carried out purposively, considering that Barugae Village is one of the centers for developing elephant ginger in Maros Regency. The purpose of this study was to analyze (1) the implementation of elephant ginger farming, (2) the production and income of elephant ginger farming, and (3) the feasibility level of elephant ginger farming. The method used in selecting the sample is simple random sampling. This study uses descriptive analysis, production and income analysis, and feasibility analysis. The results showed that the implementation of the elephant ginger farming agribusiness system did not work well because the farming subsystem needed to comply with the advice of extension agents, and support services were generally unavailable. The average elephant ginger production at the farm level is 3,029.41 kg, the production per hectare is 6,885.03 kg/Ha, and the average income of farmers is Rp. 18,176,470.59, and the income per hectare is Rp. 41,310,160.43 /Ha. The income level of elephant ginger farming received by farmers is IDR 17,151,241.69 and IDR 38,980,094.75 / Ha. The value of the R/C - a ratio of elephant ginger farming is 17.73, meaning that elephant ginger farming in Barugae Village, Mallawa District, Maros Regency, is feasible and profitable because the amount of revenue is higher than the costs incurred.

Abstract

One of the efforts to accelerate the seeds' dormancy period is to use physiologically mature seeds and applicant of endophytic fungi. This study aims to determine the level of fruit maturity and the type of fungus that can accelerate germination and growth. This research was arranged with a Randomized Block Design with 2 treatments, namely the level of fruit maturity (based on the color) and the type of endophytic fungus. The maturity level of coffee cherries (coffee fruit skin color) consists of 4 levels, namely: brown, red, orange, and yellow. The second factor is the type of endophytic fungus with 2 levels, namely: isolate CE-1, isolate CE-5, and as control without endophytic fungi. The parameters observed were the percentage of germination (%), cotyledon rupture (days), fully open Institute leaves (days), the emergence of the first leaf (days), seedling height (cm), number of leaves (strands), root length (cm), weight plant fresh weight (gr), root fresh weight (gr), leaf root weight (gr), plant dry weight (gr), root dry weight (gr), leaf dry weight (gr). The results showed that the maturity level of coffee cherries significantly affected the percentage of germination, emergence of the first leaves, and plant fresh weight. The best fruit maturity level for the percentage of germination was red with 98.5% germination percentage, first leaf appearance (44 days), and plant fresh weight (0.25 g). The type of endophytic fungus isolate had a significant effect on the percentage of germination, fully open Institute leaves, and the emergence of the first leaves. The endophytic fungus CE-5 showed the best results in the percentage of germination parameters (93.06%), fully open institutional leaves (28 days), and first leaf emergence (46 days). The use of red coffee cherries with the application of endophytic fungi can be used to germinate and growth of coffee seedlings.

Abstract

Indonesia's flora germplasm diversity can be used as a potential source of natural growth regulators. The study's goal was to compare the auxin, cytokinin, and gibberellin content of various horticultural plant extracts: onion tubers (Allium ascalonicum), a banana weevil (Musa x paradisiaca), Moringa leaves (Moringa oleifera), sweet corn seeds (Zea mays), and green bean sprouts (Vigna radiata). The research was carried out at Jenderal Sudirman University's Research Laboratory from June 2019 to February 2020. The sample was prepared in the Chemical Laboratory of the Ministry of Agriculture's Postharvest Center in Bogor for analysis of auxin (IAA/Indole Acetic Acid), cytokinins (kinetin and zeatin), and gibberellins (GA3/ Gibberellic Acid). RAL (Completely Randomized Design) was used as the experimental design. The F test and Duncan Multiple Range Test (DMRT) were used to further examine the data. Endogenous hormone content was determined in five ingredients: shallot bulbs (Allium ascalonicum), banana hump (Musa x paradisiaca), Moringa leaves (Moringa oleifera), sweet corn seeds (Zea mays), and green bean sprouts (Vigna radiata). Moringa leaves had the highest IAA content, 662.17 ppm, according to the findings. Similarly, the highest kinetin content was found in banana weevil and Moringa leaves, with 178.82 ppm and 161.37 ppm, respectively. Shallot bulbs had the highest GA3 content, at 594.12 ppm. This demonstrates that the four plant types can be used as sources of plant hormones.

Abstract

One of the inhibiting factors in providing sugar palm seeds is the dormancy period of sugar palm seeds and the growth of germs that take a long time. This study aims to determine the type of isolate and the application dose of endophytic fungus isolates that can accelerate the growth of sugar palm seedlings. The study was arranged using a Randomized Block Design (RAK) with 2 treatments. The first treatment was the type of endophytic fungus isolate consisting of 3 levels: isolates C1, C2, and C3. The application dose of endophytic fungus isolate consists of 3 levels, namely: 5 g, 10 g, and 15 g. Parameters observed were shoot emergence, plant height, root length, plant fresh weight, fresh root weight, plant dry weight, and root dry weight. The results showed that endophytic fungi isolates C1 and C3 could increase the growth and biomass of sugar palm seedlings, while the best application dose of endophytic fungi was 5 g. Application of endophytic fungi isolates C1 and C3 with a quantity of 5 g increased the growth and biomass of sugar palm seedlings.

Abstract

Aquilaria malaccensis Lam. is a gaharu-producing plant with excellent quality and high social, cultural, and economic values. Gaharu is one of the non-timber forest products with many uses, namely as a raw material for medicines, cosmetics, perfumes, incense, and preservative accessories. Gaharu is quite rare, although its cultivation can be done generatively or vegetatively. In connection with cultivation activities, quality agarwood seeds are needed. One way to do this is by giving Growth Regulatory Substances (ZPT). This study aims to determine the effect of different concentrations of shallot extract on the growth of gaharu (Aquilaria malaccensis Lam) stem cuttings. This study was arranged in a completely randomized design (CRD) consisting of 5 treatments and 3 replications, and each treatment used 5 stem cuttings. The treatment consisted of ZPT from shallots which consisted of 5 concentrations, namely: without ZPT, concentrations of 10%, 20%, 30%, and 40%. The data obtained were analyzed by analysis of variance (ANOVA), and a 5% BNT test was performed. The concentration of shallot extract significantly affected the growth of stem cuttings of Aquilaria malaccensis Lam, best at a concentration of 40%.

Abstract

Aquilaria malaccensis Lam. is a gaharu-producing plant with excellent quality and high social, cultural, and economic values. Ylang-ylang plants (Canangium odoratum forma genuina) in Indonesia are forma Guinena familia Annonaceae which have many benefits. One of the benefits is as a producer of essential oils produced from the distillation of flowers. Ylang-ylang plants can be propagated generative and vegetative, but currently, many are done in a generative way. For this reason, a study was carried out to know the composition of plant media in increasing the viability of ylang-ylang (Canangium odoratum forma genuina) seeds. The study was arranged experimentally using a factorial design based on a completely randomized design in a greenhouse. The first factor was the planting medium consisting of andosol soil, andosol soil + citronella ash, ultisol + manure, and sawdust planting medium. While the second factor was the size of the seeds, namely seeds from large, medium, and small fruit, each treatment combination was repeated three times. Parameters observed were fruit weight for each characteristic, dry weight of 50 seeds/seed, germination power, growth speed, and vegetative growth of seeds (seed height, number of leaves, leaf length, leaf width, number of roots, root length, and biomass). The research results were that the weight of large fruit was 3.016 – 4.749 g, with a significant seed weight of 0.054 – 0.056g, the best germination in andosol medium large fruit 57.78% early germination on the 40th day after sowing. The vegetative growth is a seed height of 6.60 cm, the average number of leaves is 6.05 leaves, the length of the leaves is 5.41 cm, and the width is 1.94 cm. A number of roots is 7.00 pieces, with root length of 13.50 cm with 17.62 g biomass.
