Abstract

The use of plants as traditional medicine has been known since long time ago by people in Lipu. This process has been inherited from one to next generation, nevertheless. nowdays, it has started to be extincted. So, it should be better to indentify the species of plant used as traditional medicine by people in Lipu. The research aims to investigate thekinds of plant which uses as traditional medicine. The part of plant used and how to process and the adventage of the plant. The research used explorative survey method. The result of the research there are 54 species from 31 family of plants used as traditional medicine by the people. The parts used of plant are leaf, stem/bark, root, flower, fruit, seed, tuber,rhizome and sap. The processing of the plants by refine, boil, squeeze, parch, pour boiling water, rasp and without processing. And the ability of the plants are can treat kinds of disease.

Abstract

ABSTRAKPenelitian ini bertujuan untuk mengetahui karakteristik morfologi dan pengelompokkan jenis anggrek alam (Orchidaceae) koleksi Kebun Raya Universitas Halu Oleo. Jenis penelitian ini digunakan adalah deskriptif kuantitatif. Data dianalisis menggunakan program Multy Variate Statistical Package (MVSP) versi 3.1 untuk mengetahui tingkat kemiripan dan pengelompokan antara jenis. Sampel penelitian  yaitu jenis anggrek pilihan yang sehat untuk diamati sifat berdasarkan scoring panduan karakterisasi anggrek (BPTH, 2007). Karakterisasi dalam pemberian scoring menunjukkan hasil Pengelompokkan berdasarkan sistem klasifikasi dengan fenogram presentase kemiripan  berdasarkan karakter vegetatif dan generatif dari 12 jenis anggrek asal TNRAW, hasil pengelompokan  yaitu semua spesies termasuk dalam satu sub famili Epidendroideae, karena tergolong habitus epifit dan terbagi kedalam 3 tribus dan 3 sub tribus dengan persentase berbeda. Tribus (Vandeae) sub tribus (Aeridinae) terdapat 9 spesies tingkat persentase 77,9%-89,3%. Tribus (Dendrobieae) sub tribus (Dendrobiineae) terdapat 2 spesies tingkat persentase 87,9%. Tribus (Podochileae) sub tribus yaitu (Bulbophyllinae) 1 spesies tingkat persentase 67,7%.  Kata kunci: Morfologi, Anggrek Alam (Orchidaceae), MVSP, Fenogram ABSTRACTThis study aimed to determine the characteristics of morphology and grouping of natural orchid species (Orchidaceae) collection of Botanical Gardenof Halu Oleo University. The type of research used was descriptive quantitative data analyzed. Data were analyzed using Multy Variate Statistical Package (MVSP) program version 3.1 to determine the level of similarity between types. The research sample was the type of orchid choiceof healthy to be observed nature based on orchid characterization guidebook (BPTH, 2007). Result of research based on phenogram character of vegetative and generative morphology, from 12 species of orchid had characteristic belonging to epiphytic habitus and growth type that was monopodial (7) type and sympodial (5). Pseudobulb types were clump type, chain, new pseudobulb (keiky), each type had (1) type. Leaf shape was straight / slightly inverted (2), needle-shaped (1), langset breech (2), spike grease and thick (2), oval / oblong (2), wavy (1), triangle (1), spear (1). Flowering type was cluster type (9), erect (1), panicle (1), like umbrella (1). Root type was the adhesive root (10), the air roots (2). Grouping of orchids based on existing phenograms and classification systems: subfamily Epidendroideae, tribus (Vandeae) sub tribus (Aeridinae) there were 9 species percentage levels of 77.9% -89.3%. Tribus (Dendrobieae) sub tribus (Dendrobiineae) there were 2 species percentage 87.9%. Tribus (Podochileae) sub tribus (Bulbophyllinae) 1 species percentage rate 67.7%. Keywords: Morphology, Orchidaceae, MVSP, Phenogram

Abstract

This study aimed to determine the effect of planting media and shoot pruning on the vegetative growth of the tapak dara (Catharanthus roseus (L.) G. Don) plant. The research method was factorial completely randomized design (CRD) with a combination of planting media and shoot pruning. The treatments were ultisol soil media (M0), a mixture of husk charcoal in a ratio of 1:1 (M1) and 1:2 (M2) with a pruning frequency of no shoot pruning (P0), 1 time pruning (P2) and 2 shoots pruning (P2), so that 9 treatment combinations were obtained, namely M0P0, M0P1, M0P2, M1P0, M1P1, M1P2, M2P0, M2P1 and M2P2, each treatment consisted of 3 replications so that the all sample of media used in this study was 27 polybags. Parameters observed in this study were vegetative growth including plant height (cm), number of branches, number of leaves (strands). The results showed that the planting medium and shoot pruning had a significant effect on the vegetative growth of the tapak dara (Catharanthus roseus (L) G. Don) plant which included plant height, number of branches and number of leaves, where the best plant height measurement was the M2P0 treatment with height the plant reaches 23.5 cm. The highest number of branches was produced in the M2P2 treatment with an average number of branches, which was 7.3. The highest number of leaves was in the M1P1 treatment with the number of leaves reaching 40 strands.

Abstract

This study aimed to investigate the the characteristics of biocellulose-based edible films from sago wastewater (Metroxylon sago ROTTB.) by incorporating varying concentrations of glycerol as a plasticizer. The edible films were made through a casting method using biocellulose from sago wastewater as the main ingredient. The treatments included the addition of varying glycerol concentrations to the edible films, namely 0.5, 1, and 1.5% (v/v), with three replications. The observed characteristics included physical (thickness, solubility, and moisture content of the film), mechanical (tensile strength, elongation percentage, and Young’s modulus/modulus of elasticity) with a universal testing machine, chemical structure using FT-IR, and surface morphological characteristics through scanning electron microscopy (SEM). The results showed that increasing the glycerol concentration in the edible films improved the physical characteristics including thickness, solubility, and moisture. However, there was a decrease in the mechanical characteristics, namely tensile strength, elongation percentage, and Young’s modulus of the film. The main components of edible films found were cellulose polymers, as indicated by characteristic functional groups, such as free-OH groups, aliphatic C-H, C-O, and β-1,4-glycosidic bonds. The surface morphology of the biocellulose edible film without glycerol was smoother compared to those containing glycerol. Biocellulose-based edible films from sago wastewater with glycerol concentrations of 0.5% and 1% showed physical-mechanical characteristics that fulfilled the Japanese Industrial Standard (JSI), indicating the potential for application as food packaging. These results indicated that incorporation of glycerol has an effect on the characteristics of the biocellulose-based edible films from sago wastewater.
