Abstract

The area of RW 01 Rawamangun, Pulogadung District, East Jakarta does not have an allocation of open land, so there is a minimum of green yards. The technology introduced in this community service activity is the cultivation of family medicinal plants in yards using the verticulture method. The purpose of this community service activity is to convey information about the cultivation of family medicinal plants through lectures, discussions, and direct practice of cultivating family medicinal plants in yards using the verticulture method. Evaluation of participants' knowledge improvement was carried out by pre- and post test after counseling and cultivation practices. Skills participants are carried out when evaluating the practice of cultivating medicinal plants in their yards. The results of the activity showed an increase in basic knowledge regarding the types, benefits, and techniques of cultivating family medicinal plants from technology. Family medicinal plant service activity is classified as successful and beneficial, due to increased knowledge more than 60 in average test scoring. The skills evaluation showed that some residents were able to plant and maintain family medicinal plants on a narrow plot of land using the proper verticulture method. The results of the cultivation of these medicinal plants, apart from being one of the real actions of plant greening, can also be in the form of powder products which can then be consumed as a body health measure or sold.

Abstract

In vitro medium-term storage using the alginate-encapsulation technique is essential for conserving plant genetic resources, preserving vegetatively propagated species by controlling the growth and development of explants, and maintaining plant biodiversity. The study aimed to obtain the optimum combination medium for the encapsulation of bananas and evaluate the viability of the alginate-encapsulated explants after storage. In vitro, medium- term storage of nodule-like meristem of banana cultivar ‘Barangan’ was performed using sodium alginate, paclobutrazol (PBZ), and Murashige and Skoog (MS) salt. This research consists of 3 stages: (1) Initiation and multiplication of in vitro shoots and nodule-like meristems; (2) In vitro medium-term storage of banana by encapsulation technique; (3) Regeneration of nodule-like meristem explants after in vitro storage. This research showed that the banana's number of nodule-like meristem was optimum on media supplemented with thidiazuron (TDZ) 0.22 mgL-1 and indole 3-acetic acid (IAA) 1.75 mgL-1. Encapsulation explant of nodules-like meristems using 3% sodium alginate in full and half-strength MS salt medium supplemented with PBZ 2.5 mgL-1 and incubated in liquid MS medium was able to store nodule-like meristem for six months. The color of the explants remains green, and the capsule is not damaged. Sub-culture of nodule-like meristem after storage in MS salt medium containing TDZ 0.22 mgL-1 and IAA 1.75 mgL-1 showed that nodules-like meristems could regenerate to form new shoots and nodule-like meristem three months after sub-cultured. This research concludes that encapsulated nodule-like meristem was recorded until six months of storage. PBZ was a necessary retardant in minimizing the growth during storage.

Abstract

Strawberry (Fragaria sp.) is a horticultural plant originating from the Americas. Strawberries have a distinctive sweet and refreshing taste, and contain lots of vitamins and antioxidants that are useful for body health. But strawberries are also easily damaged. This damage can be caused by spoilage microorganisms such as bacteria and fungi that can grow if conditions permit such as the presence of appropriate temperature and humidity conditions. In this experiment, aims to isolate pathogenic microorganisms that cause disease in symptomatic strawberries and prove that these pathogens actually cause disease using Koch's Postulates method and then descriptive analysis is carried out. From the experimental results, it was found that soft rot disease in strawberries was characterized by rotten fruit parts that looked wet, slightly brownish in color, slimy, there were fine white threads and emitted a foul odor with a percentage of IP (disease occurrence) of 100% and KP (disease severity) of 92.66% where based on the score the damage was the highest.

Abstract

As a megadiversity country, Indonesia is home to a large number of flora and fauna, one of which is the butterfly. The Bogor Botanical Garden, situated at the center of Bogor City, not only serves as a green open space but also as a conservation area for plants and animals composed in it.  This study aimed to assess the diversity of butterfly species in Teijsmann Park and Soedjana Kassan Park, Bogor Botanical Garden through inventory and identification.  Sampling was carried out at spots that were 100 meters apart from each other on a walked-line transect defined at the two parks. The diversity parameters assessed and analyzed are relative abundance, relative frequency, Shannon-Wiener (H’) diversity index, Evenness index (E), and dominance.  In a total of 202 sample individuals, there were identified 38 species of butterflies belonging to 5 families namely Papilionidae, Pieridae, Nymphalidae, Lycaenidae, and Hesperiidae. The highest abundance found in Teijsmann Park is Ypthima philomela from the Nymphalidae family and Zizina otis from the Lycaenidae family. Species with the highest frequency are Junonia hedonia and Ypthima philomela from the Nymphalidae family. On the other hand, the highest frequency and abundance found in Soedjana Kassan Park was Leptosia nina from the Pieridae family. Teijsmann Park showed a slightly higher value of diversity and evenness indexes (H'=2.62, E=0.84) when compared to Soedjana Kassan Park (H'=2.50, E=0.76).

Abstract

The potato plant (Solanum tuberosum L.) is a perennial crop that contains high amounts of carbohydrates, minerals, and vitamins in its tubers, making it a carbohydrate-rich alternative food to rice or corn. One of the diseases that often appear on potato plants is potato rot caused by pathogenic molds. This study aims to isolate and characterize pathogenic fungi that cause blight on potato tubers based on Koch's Postulates. Potato pathogenic molds were isolated from potato tubers that had been rotted, then the molds were grown on PDA and purified twice. The purified isolates were then inoculated onto 30 healthy potato tubers and incubated for 7 days. Healthy potato tubers experienced the same symptoms as potato tuber rot. The isolated pathogenic fungi were then characterized so that the pathogenic fungi of Phytophthora infestans were obtained. In this study, Koch's Postulate method was successfully applied to isolate and characterize the pathogenic fungi that cause potato tuber rot. The pathogenic fungi caused a potato tuber rot disease incidence value of 100% with a disease severity value of 60.7%. The two factors that determine the disease incidence and disease severity values are internal factors (genes and traits of the pathogen) and external factors (environment).
