Abstract

  Banana has been known as one of fruits that has an important function in the rural areas. Bananas have been traditionally planted by rural farmers in the homegarden, garden and mixed-garden in West Java. However, study on bananas in Karangwangi village,Cianjur has not been carried out. Aim of study was to explore varieties (landraces) of bananas, source of local knowledge on bananas, utilization of ba-nanas and diseases of bananas. Method used in this study was quali-tative with ethnobotanical approach and some techniques, including observation and semi-structure interview were applied in this study. The result of study showed that, it was recorded 13 variations of ba-nana; main source of local knowledge on bananas from the parent and friends; utilization of bananas, including consumption of ripe fruit, made of “sale” and some banana organs, including leaves, “jantung” (male flower), pseudostem, ”bonggol” (base of pseudostem) and roots of bananas were usually used by people. Main diseases of banana was known by local people as “Pireus” (virus). We recommended more intensive study on bananas must be carried on for near future.

Abstract

The natural occurrence of solar eclipses can cause various impact on bird species. The purpose of this study was to examine the effect of the partial solar eclipses on changes in behavior of three species of Ardeidae in the Rancabayawak, Gedebage, Bandung, West Java. The research method used was qualitative which direct observation sampling technique was applied.  The results of study showed that three bird species of Ardeidae namely Javan Pond-Heron (Ardeola speciosa Horsfield 1821), Buffalo Egret (Bubulcus ibis Linnaeus 1758, and small egrets (Egretta garzetta Linnaeus 1766) with total population 566 individuals were recorded in the resting and breeding place of bamboo trees and surrounding area of Rancabayawak during the partial solar eclipse.The behavior of these tree bird species, including sound of chicks, sunbathing, preening the feather, and flying of individual adults went out the resting and breeding place of bamboo trees observed tend to be normal before occurring the partial solar eclipse. During the partial solar eclipse, however, the sound of the chick stopped for a second. Some individual adult birds stopped involve in preening their feather. While, some adult individual birds were flying go back to the nest of bamboo trees that may be assumed it has already late afternoon due to dark of sun shine. Implication of this research have been considered to be very important for contributing the scientific knowledge on bird behavior changes caused by natural phenomena of the partial solar eclipse.

Abstract

Treatment with natural ingredients is essential for healing incision wounds. One promising natural remedy is land snail mucus, which has been used for centuries to address various health conditions, including wounds. This study aimed to evaluate the effects of mucus from Amphidromus palaceus and Lissachatina fulica on collagen density during the healing process of incision wounds in Rattus norvegicus. The in vivo study included 36 rats, divided into four cages with nine rats per cage. Each of rats subjected to approximately 1 cm incision wounds on their backs. The rats were divided into four groups: a negative control group (KN) receiving aquades, a positive control group (KP) treated with 1% bioplacenton, treatment group 1 (P1) receiving 25 µL of A. palaceus mucus, and treatment group 2 (P2) receiving 25 µL of L. fulica mucus. The experiment concluded on days H3, H5, H7, and H10. Histological preparations were made using MT staining to assess collagen density. The results showed both species of snail mucus significantly increased collagen density compared to the negative control (aquades). However, there were no statistically significant differences when comparing L. fulica, A. palaceus, and bioplacenton. Among all the treatment groups, L. fulica mucus (P2) produced the highest collagen density. These findings suggest that both types of snail mucus hold promising potential in promoting the wound healing process.

Abstract

One of the emerging technologies that has gained attention as an alternative for meeting renewable energy demands is the Organic Solar Cell (OSC). OSC is a type of photovoltaic device that utilizes organic electronic materials. The fundamental operating principle of OSC is based on the Highest Occupied Molecular Orbital (HOMO) and the Lowest Unoccupied Molecular Orbital (LUMO), with organic compounds serving as the active materials, enabling the conversion of light energy into electricity. Research on OSC has continuously evolved over the years to achieve optimal performance. The substrate/transport layer, which serves as the foundation for the organic active layer in OSC, can be categorized into several types, including ITO-based OSC, conducting polymer-based OSC, silver nanowire-based OSC, metal-based OSC, and graphene-based OSC. Organic solar cells offer several promising prospects, such as relatively low production costs, as well as flexible and transparent design features. However, OSCs also face several challenges, including relatively low efficiency and environmental stability concerns. Addressing these challenges is crucial to unlocking the full potential of OSC technology. This article first provides a general overview of OSC advancements, followed by a summary and analysis of its working principles, performance parameters, and structural components. Finally, we explore recent breakthroughs in OSC development in detail.
