Abstract

This study aims to determine the species of ground cover plant as well as important value index, the level of species diversity and distribution pattern of ground cover in Nature Reserve and Nature Park of Telaga Warna. This research  used the transect method and data collection were using field observation technique. The area of observation consists of three locations with different altitudes including 1400, 1500 and 1600 m asl. Each location is made of three transects that lengthwise the topography. Each transect consists of 10 sample plots measuring 1 x 1 meter with transects spaced 10 meters. Ground cover plant are found as many as 28 species consisting of 20 families. Based on the Important Value Index/INP, obtained the species that dominates at 1400 m asl is Impatiens chonoceras, while at 1500 and 1600 m asl is Scleria laevis. Based on the index of diversity was found that the level of diversity at each location is currently abundant. Based on the index of dispersion was found that the dispersion patterns of ground cover plant at each location is clumped. Keywords:  ground cover plant, Nature Reserve and Nature Park of Telaga Warna

Abstract

Weeds are detrimental due to lower agricultural yields due to competition in water acquisition, nutrients, living areas, degradation of yield quality, into host pests and diseases, poisoning plants due to toxic compounds or alleles. One of the weeds on agricultural produce is grass (Cyperus rotundus) because it has allelopathic compounds. At this time alternative weed control that is environmentally minded rampant done by looking for potency of phenol group compound from other plant so that can be utilized as bioherbisida. Babandotan (Ageratum conyzoides) containing active compounds such as saponins, flavonoids, tannins, essential oils and polyphenols are safe and environmentally friendly bioherbicides. The purpose of this study to determine the concentration of  babandotan leaf extract that can inhibit the growth of weeds teki grass. Babandotan extract is made through the maceration method. Babandotan concentrations consist of 50%, 20%, 10% and 5% and control. Phytochemical test was conducted to determine the chemical content contained in babandotan leaf. The results showed that leaf extract of babadotan can inhibit the growth of grass teki at concentration 50%.Key words: Cyperus rotundus, Ageratum conyzoides, bioherbisida

The results showed the temperature 25 oC-38oC, pH values in the range 5-7, the value of dissolved oxygen content ranged between 5.9-14.5, BOD values ranged from 5.6-7.5 mg/liter and CO2 values ranging between 11.3-13.5 mg/l due to the pollution of the natural. Net primary productivity of photosynthesis 3.2 mg/l, gross 4.3 mg/l of photosynthesis and respiration 1.1 mg/l. Plankton found Chlorophyceae, Cyanophyceae and composed Bacillariophyceae. belong to the phytoplankton and zooplankton 5 classes, namely Euglenoidae, Dapniidae, Maxillo-poda, crustaceans and Monogononta. The value of diversity index includes low range 0.05-0,149. Equity index value on Lake Cikaret range 0,009-0,064. The index value of the dominance on Lake Cikaret range 0.01-0,972. Key words : Lake Cikaret  Cikaret,water quality, plankton

Abstract

Sargassum crassifolium is a species that is included in the class Phaeophyceae.  This Brown algae is a alginat source manufacturer and contain active compounds include flavonoids, saponins and triterpenoid which function as antibacterial, antiviral and antifungal  properties. The purpose of this research is to know the activities of Sargassum crassifolium in inhibiting the growth of Candida albicans and phytochemicals content. The extraction is done using the method of maceration. Test the effectiveness of antifungal performed using diffusion agar method and paper discs. The parameters observed were drag area width. Data was analyzed using Anova with a level of confidence of 95%. The results showed that the average diameter of the drag area extract Sargassum crassifolium is most effective on a 75% concentration of 21.6 mm. Phytochemical analysis shows that Sargassum crassifolium contains the active compounds such as flavonoids, saponins, and triterpenoid. Key words  : Sargassum crassifolium, Candida albicans, antifungal

Abstract

Antibacterial potency of some seaweed against Escherichia coli has been known. The aim of this research is to know the species of seaweeds from Bayah beach Lebak Banten which may be used as antibacterial against Escherichia coli. Twenty one seaweed species samples from Bayah Beach Lebak Banten were exstracted by organic solvent of absolute methanol according to Espeche, Fraile, and Mayer (1984) and Darusman, Sayuti, Komar & Pamungkas (1992) methods. The antibacterial activities were examined by means of Kirby-Bauer or diffusion method. The results showed antibacterial activities occur from the extract of Boodlea composite, Chaetomorpha crassa, Ulva fasciata, Sargassum crustaefolium, Padina australis and Halimeda gracilis. Sofar, Padina australis extract had shown better inhibitory activities than others.

Abstract

The research aims to detect the combined deficiency of two nutrients. Those are nitrogen (N) and phosphorus (P), and phosphorus and potassium (K). Here, it is referred to as nutrient deficiencies of N and P and P and K. The researchers use the characteristics of Red, Green, Blue (RGB) color and Sobel edge detection for leaf shape detection and Artificial Neural Networks (ANN) for the identification process to make the application of nutrient differentiation identification in cucumber. The data of plant images consist of 450 training data and 150 testing data. The results of identifying nutrient deficiencies in plants using backpropagation neural networks are carried out in three tests. First, using RGB color extraction and Sobel edge detection, the researchers show 65.36% accuracy. Second, using RGB color extraction, it has 70.25% accuracy. Last, with Sobel edge detection, it has 59.52% accuracy.

Abstract

Digital dictionaries have been widely used to facilitate word processing and word search through digital media such as mobile phones. Society generally knows the efficacy and how to mix medicinal plants from the experience of previous parents or through books and writings. Searching through books or writings requires a short time compared to searching through digital media, one of which is a digital dictionary. The research aims to create a digital dictionary of mobile-based medicinal plants which has a search facility based on the words entered, for example, the contents of the medicinal plants. The digital dictionary application of medicinal plants uses a search method with the Rocchio algorithm with relevance feedback techniques to check the proximity of the query to the average document relevant to the level of similarity calculation through the stages of tokenizing, filtering, stemming, and Term Weighting with a total data of 200 medicinal plants.
