Abstract

Anatomical structure of medicinal plants wich are used in diabetic therapy is not yet completely identified. This research was conducted to study the structure of their secretory tissues. Observation of anatomical structure of leaves was done by making paradermal and transversal sections, while observation of anatomical structure of stem, fruits, and rhizomes were performed by making transversal sections. Microscopic observation found several types os secretory structure in plant organs observed. Glandular hairs were found in kiurat (Plantago mayor L.) leaves, sambiloto (Andrographis paniculata (Burm.f) Wallich ex Nees) leaves, and kumis kucing (Orthosiphon aristatus (Blume) Miq.) leaves; lithocysts cell were found in sambiloto leaves; oil cavity/cells were found in salam (Syzygium polyanthim (Wight) Walp.) leaves, jambu (Psidium guajava L.) leaves, lada (Piper nigrum L.) fruits, and jahe (Zingiber officinale Roscoe) rhizomes; idioblast cells wich contained starch grains were found in brotowali (Tinospora crispa (L.) Miers) stems, lada fruits, and jahe rhizomes; and latex cells were found in brotowali stems.

Abstract

Antioxidant has an important role in healing some kind of dieses caused by excessive oxidation reactions in human body. That leaf has benefit to resist diarrhea, anti inflammation, and anti mutagenic. It is assumed it could be used as antioxidant. The research was aimed to know the antioxidant activity of the extract of Psidium guajava leaf. The local leaf was from Bantar Kambing area in Bogor. The methods were thiocyanate method and thiobarbituric acid (TBA) method. The result showed that the leaf wich had the best antioxidant potential was the white local Psidium guajava leaf extracted by ethanol 70% in a maceration manner. In the tyochianate method, the extract of white Psidium guajava leaf had protective factor near to Vitamin E or tocopherol, that is 1.10 and tocoferol was 1.16. antioxidative evaluation using the TBA method showed that the highest activity was from ethanol extract of white  Psidium guajava leaf could obstruct it up to 94.19% toward the control, however the actif constituents are unknown. Phytochemical evaluation result showed that the Psidium guajava leaf are contained tannin, phenol, flavonoid, quinon, and steroid.

Abstract

Mealybug can almost be found in all pineapple fields (Ananas comosus (Linnaeus)). The insect is known to be a vector of Pineapple Mealybug wilt-associated Virus (PMWaV). The insect samples taken from pineapple in Bunihayu, Jalancagak, Subang, West Java, were identified in laboratory. Mealybug-ant symbionts were also taken. The ability of this ant to carry the mealybugs from colony reared on kabocha (Cucurbita maxima) to pineapple was also tested at green house level. Only one spesies of mealybug was found on pineapple, i.e. Dysmicoccus brevipes (Cockerell) (Hemiptera: Pseudococcidae). The mealybugs were found to colonize root, basal of stem and the leaf. Eight ant species were found to be associated with mealybug. There are four species belongs to Pseudolasius genera, two species Cardiocondyla genera, Paratrechina sp. and Dorylus sp. Paratrechina sp. showed the ability to carry D. brevipes from kabocha population to pineapple. Therefore the ants should also be controlled in the total management of PMWav.

Abstract

The purpose of this study was to examined the effectivity of Aloe vera gel formulation on the skin wound healing process based on the macroscopic and microscopic observation. Fourty five DDY strain, 6-8 weeks old mice were used for experimental animals. Mice were incised 1-1.5 cm in the dorsum using sterile scalpels. Mice were divided into three groups. Group I (control) were not treated by anything, Group II were treated by commercial drugs (Bioplacenton), and Group III were treated by Aloe vera gel. Bioplacenton and Aloe vera gel were given topically twice a day to the skin using sterile cotton buds. Each groups consisted of 15 mice and distributed into 5 observation days with 3 replication. Three mice from each groups were euthanized periodically at day 3rd, 5th, 7th, 14th, and 21st post incision for gross pathology examination and to sampling the skin. Gross examination revealed that Bioplacenton and Aloe vera gel showed better result on wound healing process, i.e. the scab formation, scab peeler and unite of the wounded skin edge compared to the control groups. Microscopically, the Bioplacenton and Aloe vera gel groups showed the fastest epidermal re-epithelization compared with the control group. Qualitatively Bioplacenton and Aloe vera gel groups showed more fibrosis and collagen fibres formation than the control groups especially at day 7th and 14th. Scoring Average of neocapillaries formation from all groups showed no difference. Scoring average of inflammatory cells number revealed that control groups showed more cells than the other groups that indicated an high inflammatory activity. Based on macroscopic and microscopic examination we suggest that the Aloe vera gel formulation has a benefit to promote wound healing, and could be used for the treatment of skin wound. Thus, the Aloe vera gel formulation is potential to developed as commercial drugs.

Abstract

Nowadays, wood industry in Indonesia suffers from lack of wooden raw material because of the demand is greater than the supply. In order to solve this problem, we need to enhance the use of wood by optimalizing the use of wooden raw material wich has a great potensial, but not well used, for example hybride coconut wood. The purpose of this research were to determine physical, mechanical and chemical properties of hybride coconut wood and its vertically and horizontally variation in order to optimalize the use of hybride coconut wood. This research used three hybride coconut steems, the 6 cm disks were extracted from each stem at 1, 4, 7, and 10 m heights. The analyze of vascular bundle and parenchyma consisted of covered area per cm2 and their chemical composition. Hybride coconut wood had a low specific gravity because vascular bundle covered area was lower than parenchyma per cm2 and low wood substance portion. Low specific gravity caused low mechanical properties. Hight moisture content (specially fresh one) was cause by sugar and starch extractives which had high hygroscopic ability. These extractives content also caused it to be easily attacked by wood destroying factors. Parenchyma covered area per cm2 caused high sugar and starch content. Height and depth factors were visible influence at almost all basic properties of vascular bundle and parenchyma at different level.

Abstract

The Urban growth has proven give a significant effect on the hydrological watershed function. Information. Information about the impact on the water resource in such watershed could be spatially quantified using GIS tool. The response of Cicatih watershed in West Java to various scenarios was determined using SCS method. In the scenarios, the effect of an increase in settlement cover to surface runoff and water storage was examined. The results indicate that surface runoff increase to 79% and water storage decrease to 31% due to settlement expansion.

Abstract

The Objectives of this study are: (1) to identify agricultural household characteristic in rural and urban areas, (2) to identify the factors that encouraging the process of labour transformation in rural and urban areas, and (3) to analyze the process of labour transformation impact to households income in rural and urban. The design of study is the case study in the district of Bogor. The sampling method use multistage sampling with data analyzing of: (1) descriptive analysis, (2) Binary choice model in logistic function, and (3) Income analysis. The results of study show that educational level of head of agricultural household in rural more than urban and conversely for income. The factors in wich influent the decision of head of household to transform in rural are age (X3) and income expectation from non-farm (5). In urban, the factors in which influent decision are self belonging of land (X1), the amount of working age of household family members (X2), the educational level of head of household (X4), and income expectation from non-farm (x5). Income level of houshold in rural and urban is not significant (Prob 0.2906). Mean while, the average of farm income in rural and urban is significant (Prob = 0.0028). The income of transformed farmer is more than pure farmer. The income level significant both rural (Prob = 0.0618) and urban (0.0110).
