Abstract

The resistance character and infection pathogenicity of bacteria to humans is currently increasing, so there is a need for new alternative drugs. The bioactive compounds contained in katang-katang plant are one of the new sources of antibacterials obtained from nature. This study used leaves and flower samples of Katang-katang (Ipomoea pes-caprae (L)R.Br) obtained from the coastal area of Bengkulu City. The purpose of this study was to determine the phytochemical compounds of the leaves and flower extracts of Katang-katang using color reaction test method and to determine the antibacterial activity of the extracts of the leaves and flowers of Katang-katang against the testing pathogenic bacteria (Pseudomonas aeruginosa) at concentrations of 10%,25%,50%,75% using disc diffusion method. The leaves and flowers ethanolic extracts of the Katang - katang were proven contain secondary metabolites such as alkaloids, flavanoids, saponins, tannins and steroids. Antibacterial effectiveness of the ethanol extract from leaves was classified as moderate at a concentration of 50% with a measured inhibition zone of  6.30 mm and a concentration of 75% with an inhibition zone size 8.13 mm. In contrast, effectiveness of the antibacterial extracted from flower was classified as weak at a concentration of 50% with an inhibition zone 4.50mm and moderate at a concentration of 75% with a measured inhibition zone size of 6.40 mm. The experiment revealed that the leaves and flowers of the Katang-katang have antibacterial potential against P. aeruginosa which could be developed as a medicinal ingredient in the future

Abstract

Maintaining bird diversity is essential for preserving biodiversity. The popularity of bird keeping as a hobby is due to their attractive colours and sounds, as well as their economic value. However, the breeding and trading of various bird species has led to the development of bird races and competitions. This study aims to determine the diversity, dominance, and conservation status of songbird species that are traded and competed in Jambi City. The study is a descriptive field research that showcases our expertise in the field. In August 2023, the study confidently employed structured observations and interviews through a questionnaire.   The analysis confidently used the variety index, evenness index, and dominance index. The research confidently identified ten species, two of which are protected: The Cucak hijau Chloropsis sonneratii (Chloropseidae) and the Serindit melayu Loriculus galgulus (Psittacidae). The bird species have been classified into three categories based on their IUCN conservation status: endangered (10%) Chloropsis sonneratii, vulnerable (20%) Alophoixus tephrogenys and Zosterops melanurus, and least concern (70%) Copsychus saularis, Kittacincla malabarica, Leptocoma brasiliana, Zosterops simplex, Loriculus galgulus, Agapornis sp., and Serinus canaries

Abstract

Spodoptera exigua is the main pest that attacks the onion crop. S.exigua attack can cause crop failure reaching 57%-100%. The use of natural ingredients from plants for vegetable pesticides such as papaya leaves and mahogany leaves containing secondary metabolite compounds: alkaloids, papain, saponins, tannins, terpenoids, flavonoids and steroids that can damage the feeding activity system and damage the pest growth system which eventually the pest will die. This study uses a non-factorial RAL (Completely Randomized Rack) method with 7 treatments M0= Control, M1= Papaya leaf extract 30%, M2= Papaya leaf extract 60%, M3= Mahogany leaf extract 30%, M4= Mahogany leaf extract 60%, M5 = Papaya leaf extract 15% + mahogany leaf extract 15%, M6= Papaya leaf extract 30% + mahogany leaf extract 30%. The highest mortality result is 72.50% with the treatment of 60% papaya extract vegetable pesticide and the lowest is 27.50% with the treatment of 30% mahogany extract vegetable pesticide. The initial symptoms of death of S. exigua caterpillars are characterized by larvae that are less active in moving, moving to the surface of the container, moving away from the feed, convulsing and finally dying. The mortality of S. exigua larvae at 24 JSA killed a total of 14 larvae and increased with each subsequent treatment. The results of the vegetable pesticide test on natural enemies using extracts that produce the highest percentage of mortality on S. exigua is 100%. This indicates that the extract is safe for the survival of natural enemies. Plant-based pesticides papaya leaf extract, mahogany leaves and a combination of papaya and mahogany leaves have an effect on the mortality of S. exigua caterpillars

Abstract

Extreme climate change affects human life. One of the causes of climate change is the increase of CO2 gas in the air. Forests can absorb CO2 from the air and store it in the form of tree biomass through the process of photosynthesis. One of the forests that can absorb and store carbon is Pertamina Hulu Rokan (PHR) forest, therefore it is necessary to conduct research on estimating the carbon content of PHR Forest area. The methods to be used in this research are non-destructive sampling and destructive sampling methods. The method with harvesting is only for seedlings, undergrowth and litter, while for saplings, poles, trees and necromass with the method without harvesting. Aboveground carbon storage in PHR forest was found to be 95.37 tonnes/ha. The largest carbon stocks were from trees (68.96 tonnes/ha), poles (13.06 tonnes/ha), necromas (5.70 tonnes/ha), litter (3.72 tonnes/ha), saplings (3.54 tonnes/ha) and the smallest carbon stocks were seedlings and understorey (0.39 tonnes/ha).

Abstract

The production of Dendrobium striaenopsis orchid cultivation in Indonesia has many obstacles including limited seed provision, low seed quality and cultivation techniques that have not been done well, while orchid enthusiasts always increase every year. Propagation of orchid plants by conventional means requires a long time to obtain a large number of plant saplings, therefore alternative cultivation using tissue culture techniques is needed. In vitro tissue culture techniques are widely used as a fast and efficient way to produce D. striaenopsis orchid plants, but not infrequently there are factors that affect the production of orchids, one of which is bottle size.  The purpose of this study is to determine the effect of the effectiveness of bottle size variations on the growth of        D. striaenopsis plantlets after comparing the difference in bottle volume and knowing the optimum size of bottles used for D. striaenopsis plantlet growth. The study was conducted from May to August 2023 in the Laboratory CV. Candi Orchid, Semarang City. The method used was the observation and experimental method after which it was continued with the One Way Anova test and further test T. In this study using Vacin and Went medium with a size of 60 ml by providing treatment variations in bottle sizes of 250 ml, 500 ml and 750 ml with 4 repeats. The result of this study is that a 750 ml bottle used in the tissue culture technique of D. striaenopsis Orchid is effective in use even though the growth of plantlets does not occur a significant difference, this is due to environmental factors, namely light intensity and duration of irradiation

Abstract

Red chilies known as Capsicum annuum L., hold significant importance as horticulture crops in Indonesia. The production of red chilies begins with the planting of seeds, making seed health a crucial factor in the process. Seeds contaminated with pathogens can serve as a reservoir for the transmission of diseases in the field, leading to the demise of seedlings and hindering their growth into fully mature plants, ultimately resulting in crop failure. This study used the blotter test technique to ascertain the morphology of a seed-borne pathogenic fungus. The research findings indicated that the blotter test technique detected four isolates of seed-borne pathogenic fungus, specifically TMIA with an infection rate of 0.5%, TMIB with an infection rate of 0.5%, TMIC with an infection rate of 2.5%, and TMIE with an infection rate of 3%. A single isolate of a seed-borne pathogenic fungus, named SRIA, was obtained from Sidodadi Ramunia village. The infection rate of this fungus was determined to be 0.5%. The chili seeds recovered were found to carry pathogenic fungal isolates belonging to Aspergillus sp., Penicillium sp., Verticillium sp., and Curvularia sp. based on morphological identification

Abstract

Comprehensive exams are administered to assess the abilities and knowledge of students in their respective scientific disciplines. However, the material's scope is quite extensive, particularly in light of the absence of a question bank or grid-based guide. However, advancements in the twenty-first century necessitate that educators possess not only knowledge of subject matter and the learning process but also proficiency in technology. TPACK (Technological Pedagogical Content Knowledge) refers to the amalgamation of stated components. The objective of this research is to develop a valid and practical question bank for biology education comprehensive exam, utilizing the TPACK framework. Research and development (R&D) was employed in accordance with the ADDIE development model. The instruments were validation sheets to determine the validity of the developed question bank and response questionnaires to assess its practicality. The validation sheet was intended for experts in learning evaluation and TPACK, whereas the response questionnaire was intended for students and examining lecturers who delivered comprehensive exams. The research findings indicated that the TPACK-based comprehensive exam question bank that was created exhibited a very high level of validity, as confirmed by 87.92% of learning evaluation experts and 88.69% of TPACK experts. The practicality test yielded a 91.68% passing rate among the examining lecturers and a 96.04% passing rate among the students. This value falls under the category of being extremely practical. Hence, it can be inferred that the developed question bank possesses validity and utility. This question bank aims to assist in preparing comprehensive exams for both students and lecturers, while also serving as a guide for developing TPACK, specifically designed for graduating students in the biology education program

Abstract

Skin infections contribute to one of the most significant global health issues. Acne, blisters, and abscesses are examples of skin infections that can be induced by Propionibacterium acnes, Staphylococcus aureus, and Staphylococcus epidermidis. Treatment can be attempted through the development of nanotechnology in the form of nanocellulose. Nanocellulose, an organic substance, can be produced through the conversion of coconut water waste and Acetobacter xylinum bacteria. Future applications of nanocellulose formulated with a blend of extracts derived from natural sources, including Patikan Kebo (Euphorbia hirta L.), are anticipated to include the treatment of wound dressings (patches). Determining the antibacterial potential of nanocellulose was the objective of this study. The experimental research technique is implemented in phases. The extraction process was conducted by means of maceration, while the parallel streak method was utilized for antibacterial testing. The findings of the study indicated that the mean zone of inhibition for each treatment variable was as follows: 0 mm, 15.1 mm, 23.53 mm, and 23.06 mm for nanocellulose (serving as the negative control), nanocellulose and 0.5% extract, 1% extract, 1.5% extract, and clindamycin, respectively. Conclusion: Antibacterial activity was observed in nanocellulose extracts containing 1% and 1.5%

Abstract

Worm infections in Javan gibbons often do not cause clinical symptoms, but have an impact on the health and performance of Javan gibbons, so a fecal examination is needed to determine the presence of worm infections in Javan gibbons. The aim of this research is to identify digestive tract worms that infect Javan gibbons at Maharani Zoo. The research was conducted on 3 Javan gibbons consisting of 2 males and 1 female with an age range of 6-14 years and a body weight of 4-6 kg. Macroscopic identification of worms in Javan gibbons showed an abnormality in one of the Javan gibbon's feces. The feces abnormality is in the form of a very soft consistency, with a brownish yellow color, and the feces has a foul odor. Microscopic identification of worms in Javan gibbons showed positive results for the presence of eggs and larvae Strongyloides in one of the Javan gibbons. The Strongyloides worm larvae identified were rhabitiform. The cause of worm infections in Javan gibbons was due to the vegetable feed given, namely water spinach and mustard greens, being contaminated with Strongyloides worm eggs. Prevention needs to be done to prevent contamination of worm eggs, including washing the vegetables.
