Abstract

Tomatoes (Lycopersicon esculentum Mill.) are a source of carotenoids they are easy to find. These compounds function as precursors of vitamin A, antioxidant, and prevent cancer. The extraction of carotenoid compounds for commercial products usually uses fresh plants, which are less efficient and require a lot of raw materials. The supply of these raw materials can be done through tissue culture. The frequency of subculture or supply of nutrients in tissue culture is very influential on the content of callus carotenoids produced. This study aimed to determine the effect of subculture frequency on growth, development and callus carotenoid content and to find out the right frequency of subculture to produce callus with optimal growth, development and carotenoid content. The design this study was a single Completely Randomized Design (CRD) with 4 treatments of subculture frequency and 5 replications. The data obtained were analyzed by ANOVA at the 95% test level followed by DMRT in case a significant different was found The results showed subculture frequency affected growth, development and carotenoid content of callus Lycopersicon esculentum. Mill. The most optimal treatment to induce growth and production of carotenoids in this study was treatment of thrice subculture while the most optimal treatment in inducing development was the twice subculture treatment.

Abstract

   Bogor Botanic Gardens is one of the outstanding green areas in Bogor City. Thousands of plant species are growing and providing suitable habitats and feed for various pollinators, such as butterflies, bees, and wasps. A well-designed pollination garden will benefit the pollinators and also create an educational facility for the community. This study aimed to select and characterize species of flowering plants that effectively attract pollinators, particularly Lepidoptera and Hymenoptera, in the pollination garden candidate area. The observa-tion had been carried out on 12 ornamental plant species: Pennisetum purpureum, Cosmos sp., Pachystachys lutea, Cuphea hyssopifolia, Orthosiphon aristatus, Lantana camara, Citrus aurantifolia, Buddleja davidii, Ixora javanica, Nerium oleander, Hibiscus rosa-sinensis, and Aglaia odorata. The method for observing pollinators was a standard walking method. Pollinator photos, its number, its visit time, and the plants it visited were recorded. A total of 23 species of Lepidoptera (20 species from 4 families and 3 species were unidentified) and 9 species of Hymenoptera (4 families) were found in the area with the best obser-vation time at 08.30-09.30 (GMT+7). The most visited plants by pollinators were Cuphea hyssopifolia, Lantana camara and Orthosiphon aristatus. Lepidoptera and Hymenoptera preferred blue-purple and bright-orange-yellow flowers. In addition, the flower characters that might influence pollinator visits are also described. The result would be an essential recommendation for plant selection, landscape design, and construction of the pollination garden in Bogor Botanic Gardens.

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

The use of bacteria as a biological control agent in aquaculture is such new hope overcoming the negative impacts of the impropriate use of antibiotics. Bacillus is widely known as a potential probiotic for aquaculture, especially which are derived from aquatic biota. Due to a concern that the role of Bacillus as a probiotic agent will be disrupted by residues of antibiotics in the water, this research aimed to identify Bacillus species from common carp intestine based on the molecular method and investigate their resistance to some com-mercial antibiotics that widely used in aquaculture. Chloramphenicol, ampicillin, and metronidazole were used to determine the Bacillus resistance to antibiotics using the Kirby Bauer method. The resistance assay was carried out with a bacterial density of 108 CFU/mL. The results showed that Bacillus isolates derived from common carp  intestine were closely related and resistant to antibiotics. Isolates that resistant to the three types of antibiotics were Cc.1.9 (CgN9) and Cc.2.18 (CgM18).

Abstract

   Some small islands in Balikpapan Bay consist of dry land which may have different vegetation structure and composition. Our study was the first to uncover vegetation conditions and soil proper-ties of dry land on small islands in Balikpapan Bay, which has never been conducted before. The research was carried out on Kalawasan and Karantina islands. Information on vegetation was obtained by applying a line transect method. Data on soil properties were col-lected by setting up 3 sampling plots in each transect of vegetation. Parameters used for analysing vegetation including relative densi-ty, relative frequency, relative dominance, Shannon-Wiener diversi-ty index, evenness index, and similarity index. Meanwhile, data on soils were analysed descriptively. Trees on Kalawasan island were comprised of 241 individuals belonging to 21 species. There were 61 individuals (22 species) of trees on Karantina island. The diver-sity index of trees on Kalawasan and Karantina island was 2.55 and 2.72, respectively. The tree evenness index was 0.84 on Kalawasan island and 0.88 on Karantina island. The index of similarity for trees between the two islands was 0.21. Furthermore, the soil character-istics on Kalawasan and Karantina islands showed similarities. In general, soil in Kalawasan and Karantina islands could be catego-rised as marginal soil which was common in East Kalimantan. Con-sidering the rapid loss of tropical forests in the mainland of Kali-mantan indicates that the small islands of Balikpapan Bay play an important role in future biodiversity conservation in East Kalimantan.

Abstract

 Javan Hawk Eagle is one of the three keys species of the Gunung Halimun Salak National Park and endemic to the island of Java. Protecting the active Javan Hawk Eagle nesting tree is one of the efforts to increase the success rate of Java Hawk Eagle breeding so that information on the distribution and characteris-tics of Javan Hawk Eagle nesting tree is needed. Field exploration was carried out to determine the existence of the Javan Hawk Eagle nest. There were 10 individuals of Javan Hawk Eagle nesting trees which consisted of 5 species namely Rasamala, Huru, Damar, Leng-sar and Manggong with tree architecture models of rauh, massart, scarrone and aubreville, tree height between 26-55 m and height of nests between 18-41m. The Javan Hawk Eagle nesting trees grow in primary, secondary, and plantation forests in a height between 670- 1295 masl, with a steep and very steep slope, the majority of the dis-tance from the river is less than 100 m and the majority of the dis-tance with ecotone is less than 600 m. Javan Hawk Eagle nest on Damar is the first finding at Gunung Halimun Salak National Park.

Abstract

 The Biological Nitrogen Fixing (BNF) cyanobacteria can reduce atmospheric nitrogen into ammonium. This ability makes BNF cyanobacteria a potential eco-friendly N-source for soil-planted pad-dy. Apart from a few success stories of BNF cyanobacteria applica-tion in the rice field, its role as an ammonium producer is still an open question. There is also a possibility that indeed cyanobacteria biomass which provides nitrogen through the biological decomposing process. This study aimed to analyze the influence of three strains BNF cyanobacteria on paddy grown in the Deep-Water Culture (DWC) hydroponic system. Yoshida Nutrient Solution was used as a growth medium with the application of 0, 45.7, and 91.4 gL-1 of ammonium nitrate (NH4NO3) with five replications. The result showed that inter-action between cyanobacteria and nitrogen significantly influenced the total nitrogen of paddy plant, but not the paddy plant height, the num-ber of tillers, and biomass. Cyanobacterial filaments were found most-ly attached to the paddy root rather than floated in the DWC system. Paddy treated with cyanobacteria had more lateral root than control. The result suggested that cyanobacteria support paddy growth indi-rectly through nitrogen deposition in plant tissue and root development.

Abstract

   Hermetia illucens (L.), the black soldier fly (BSF), has raised attention due to its potential in solving various organic waste prob-lems and the benefits of the prepupa biomass as an alternative highly nutritious livestock feed. The availability of BSF populations strongly depends on mating success and reproduction. The mechanism of sex-ual selection during the mating period also determines the success rate of mating and reproduction and the survivorship of the offspring. Here, we analyzed how the influence of different mating status (virgin-ity) of mating pairs on mating success, daily oviposition, the number of eggs and fertility of eggs. BSF reared in semi-outdoor screen cages with five replication and four treatment of mates virginity combina-tion. An analysis of variance (ANOVA) was used to assess differences in mating and reproductive performance among treatment. Male and female BSF performed the remating activity. The virginity of males and females significantly influenced mating and oviposition frequen-cy. Mate choice was influenced by the virginity of mates. However, vir-ginity status of mates did not affect the number of eggs, eggs weight, and eggs fertility. Understanding of mate selection behavior in rela-tion to virginity in BSF served as important information to obtain the sustain population in the various scale of rearing design applicat

Abstract

 This study aimed to determine the response of the growth of sweet corn plants and weed density to the treatment of bio-fertilizer based on arbuscular mycorrhizal fungi and cow manure fertilizer. The study was conducted using a randomized complete block design (RCBD) in a factorial pattern. The first factor was arbuscular mycorrhiza fungi (AMF) consisting of four doses, namely without AMF (A0), AMF 5 g/planting hole (A1), AMF 10 g/planting hole (A2), AMF 15 g/ planting hole (A3). The second factor was cow manure fertilizer con-sisting of three doses, namely without cow manure fertilizer (B0), cow manure fertilizer 3 kg/plot (B1), cow manure fertilizer 6 kg/plot (B2). The treatment applied consisted of 12 combinations of treatments with 3 replications, so there were 36 experimental units. The observed variables were plant height, stem diameter, leaf area and weed density. The results showed that the average height of sweet corn was best at 42 DAP in the treatment of cow manure fertilizer 6 kg/plot (B2) as 111.6 cm. The average highest of stems diameter was at 14 DAP in the treatment of cow manure fertilizer 6 kg/plot (B2) as 0.40 cm. The average leaf area of sweet corn was at the age of 28 DAP was highest in the combination treatments cow manure fertilizer 6 kg/ plot (A0B2) and without AMF as 894.5. The weed species with the highest density found was I.cylindrica as 0.5-32.4%, C. kyllingia as 1.3-41.8%, C. rotundus as 1.3-30.3% and F.miliaceae as 1.2-12.7%.

Abstract

Diabetic wounds lead to severe tissue damage and are diffi-cult to cure. Jengkol (Archidendron pauciflorum) is a plant commonly used by local Indonesian communities to treat diabetic wounds. The efficiency of herbal medicine still has a deficiency of its ability to reach the target organs, therefore nanotechnology is applied in the hope that all drug concentrations can reach the target organs successfully. This study aimed to evaluate the effectiveness of PLGA nanoparticle ointment-ethanol extract jengkol fruit peel (EEJFP) to accelerate the wound healing process in the skin of streptozotocin-induced diabetic mice. The research method used was experimental with a completely randomized design using six treatments and four replications. Diabe-tes was induced by intraperitoneal injection of streptozotocin 180 mg/ kg BW. Mice with a blood glucose level of ≥150 mg/dL were used for diabetic mice models. The incision wound created at the dorsolateral region of shaven skin at ±1 cm2 using sterile scissors. The treatments given were vaseline for Control Negative (CN) and Control Positive (CP), Betadine ointment (PB), 10% EEJFP ointment (P1), 5% PLGA nanoparticle ointment-EEJFP (P2), and 2.5% PLGA nanoparticle ointment-EEJFP (P3). The results showed that the administration of PLGA nanoparticles ointment-EEJFP with a concentration of 5% PLGA nanoparticle ointment-EEJFP (P2) resulted in the shortest wound length on day 3, 7 and 14; narrower granulation tissue; a larger number of blood capillaries; and denser collagen fibers (α <0.05) compared to CP and PB treatments. The administration of PLGA nanoparticle ointment-EEJFP with a concentration of 5% was the most effective concentration in accelerating wound healing in the skin of diabetic mice.
