Abstract

Agarwood (Aquilaria malaccensis Lamk) is one type of forestry plant that has been developed with tissue culture techniques. The provision of growth regulators can be done by adding in the growing media used. Growth regulators used are usually in the form of auxins and cytokines. This study aims to obtain the concentration of growth regulators with the combination of Benzyl Amino Purine (BAP) -Indole Butyric Acid (IBA) which is the best for organogenesis of aloe plants (Aquilaria Malaccensis Lamk) in vitro. This study uses a completely randomized design (CRD) method consisting of 5 BAP-IBA combination treatments namely V0 = MS0 (control), V1 = MS + 0.8ppm BAP + 0.1ppm IBA, V2 = MS + 1.0ppm BAP + 0 , 1ppm IBA, V3 = MS + 1.5ppm BAP + 0.1ppm IBA, V4 = MS + 2.0ppm BAP + 0.1ppm IBA. The parameters observed in this study were the initial emergence of shoots, the number of shoots, and a number of leaves. The Smallest Significant Difference (BNT) test was carried out if the analysis of variance showed that the BAP-IBA combination treatment had a significant effect. The results showed that the combination of BAP-IBA on various treatments that were tried had a very significant effect on the initial emergence of shoots, a number of shoots and a number of leaves. The best treatment was found in V1 with MS concentration + 0.8ppm BAP + 0.1ppm IBA was able to induce early formation of the fastest buds with an average of 5.00 days after planting (HST), the highest number of shoots with an average of 3.00 shots, the highest average number of leaves is 1.80 strands, and the highest growth percentage is 100.00%.

Abstract

The problems that are still faced at this time include the lack of enviromentally sound cultivation technology to support teak growth rates quickly and efficiently. One of the efforts to overcome this problem is to use a Gyberelin (GA3) growth regulator, which isknown to accelerate plant growth, so that dwarf plants can grow taller in a relatively short time. The research aims to determine the effect of various concentration s of administration of Gyberelin (GA3) grawth regulators on teak seedlings (Tectona grandis L.f) in nurseries. This research uses a completely randomized design method consisting of four treatments, namely G0= (Control), G1= 100 ppm, G2= 200 ppm, G3= 300 ppm. The results of the research showed that the addition of various concentrations of Gyberelin hormone in the nursery had a significant effect o the height increase and increase in the number of teak seedling leaves, but it did not signficantly affect the diameter of teak seedlings. Treatment of Gyberelin (GA3) with a concentration of 300 ppm (G3) gave the best influence on teak growth in terms of height increase and number of leves compared to control treatment (G0), as well as concentration 0f 100 ppm (G1) and 200 ppm (G2).

Abstract

Medicinal plants are medicinal plants that can relieve pain, increase endurance, prevent and cure diseases. The use of natural materials as traditional medicine in Indonesia has been carried out by our ancestors since centuries ago until now still exists, especially in the village of Malonas, Dampelas District, Donggala Regency, Central Sulawesi Province. The purpose of this study was to determine the diversity of medicinal plants in the Production Forest area of Malonas Village, Dampelas District, Donggala Regency. This research was carried out in the production forest of Malonas Village, Dampelas Subdistrict, Donggala Regency, which was held for 2 months, from July to August 2018. This study used a single plot method which was purposively placed based on the location of medicinal plants. The minimum sample plot area used is determined by the area species curve. The results of the research conducted show that the number of seedlings and understorey medicinal plants that can grow in this area is greater, because the growth rate of the lower plants has a high diversity and species richness index influenced by the topography of the slope-sloping research site and at least cover from canopy at the level of growth of poles and trees. It can be seen from the results of calculation of tree level diversity index (H ') (0.69), pole level (0.61), stake level (0.63), seedling level and understorey (1.33). So the diversity of medicinal plants according to growth rates is generally classified as low.Keywords: Malonas Village Production Forest, Medicinal Diversity

Abstract

Rattan is a plant that lives in clumps or singles and is classified into the family Arecaceae / Palmae. Determination of the type of rattan can be through identification based on the morphological character of plant organs. Classification of types of rattan is usually based on the equality of characteristics possessed by each type. Ecologically, rattan thrives in various places, both lowlands and highlands, especially in humid areas such as river banks. This study aims to determine the diversity of rattan species in the production forest area of Salukaia Village, Pamona Barat District, Poso Regency. The study was conducted in December 2015 - January 2016. This study used a survey method to select or place plots deliberately made in places where rattan was found (purporsive sampling). The number of observation lanes is 1 lane with a length of lane 1000 m and width 20 m, then a plot of 20x20 m is made. Along the observation track 30 plots were made. The data obtained were analyzed to determine density, frequency, index, importance value (INP) and diversity index. From the results of the study found 9 (nine) types of rattan namely Kuyuwi rattan (Daemonorops robusta Becc.), Tida Lingka rattan (Daemonorops sp.), Uban rattan (Calamus sp.), Hoa rattan (Calamus ornatus var. Celebicus Bl), rattan rattan (Daemonorops sp.), Uban rattan (Calamus sp.), Hoa rattan (Calamus ornatus var. Celebicus Bl), rattan rattan Bottle Tungka (Calamus inops Becc.), Laru rattan (Calamus orthostachyus Becc.), Silaya rattan (Daemonorops lamprolepsis Becc.), Batang rattan (Calamus zollingerii Becc.), And Ronti rattan (Calamus leptostachys Becc.). The dominant type of rattan at the study site was Kuyuwi (Daemonorops robusta Becc.). The level of diversity of rattan species is classified as being abundant with a value of 1.91.Keywords: Rattan Species Diversity, Production Forest Areas
