Abstract

This study aimed to analyze the management of a subcutaneous abscess in a Shih Tzu dog, including identification of the causative agent, antibiotic sensitivity testing, and evaluation of the clinical therapeutic response. The case was managed at ZZ Petcare Clinic using a systematic approach consisting of anamnesis, physical examination, ultrasonography (USG), aseptic collection of pus samples, local drainage, abscess cavity irrigation, and follow-up treatment with broad-spectrum antibiotics, amoxicillin, vitamin B complex, and topical antibiotics. Pus samples were analyzed in the laboratory for bacterial isolation and identification using biochemical tests, while hematological examination was performed to assess the patient’s systemic status. Ultrasonographic examination identified an accumulation of purulent fluid with an approximate diameter of 7 cm, accompanied by an inflammatory response in the subcutaneous tissue. Laboratory analysis of the pus revealed that the causative agent of the abscess was Staphylococcus aureus, with antibiotic susceptibility testing showing sensitivity to ciprofloxacin, intermediate susceptibility to amoxicillin, and resistance to penicillin and ceftriaxone. Initial hematological examination indicated leukocytosis and mild inflammatory anemia, with WBC and RBC values of 20.4 × 10⁹/L and 5.05 × 10⁹/L, respectively. Following therapy, the patient’s condition improved, as evidenced by normalization of white blood cell and red blood cell parameters, with WBC and RBC values of 7.8 × 10⁹/L and 7.96 × 10⁹/L, respectively. The therapy administered was sufficiently effective, as indicated by clinical improvement within five days after treatment. This study emphasizes the importance of combining local drainage procedures, appropriate wound care, and antibiotic selection based on susceptibility testing in controlling infection and promoting patient recovery.

Abstract

This study aims to analyze the influence of the agricultural and non-agricultural sectors on regional economic growth in Depok City during the 2020–2024 period. Although agricultural land area has declined to 157.42 hectares in 2024, this sector exhibits a paradoxical phenomenon in the form of an increasing growth rate, thereby necessitating a strategic evaluation of its development potential. Using Gross Regional Domestic Product (GRDP) data, this study applies the Location Quotient (LQ), Basic Service Ratio (BSR), Regional Investment Multiplier (RIM), Shift Share, and Klassen Typology methods. The results indicate that the economy of Depok City is driven by ten base sectors, including construction, trade, and financial services. Although the agricultural sector is classified as a non-base sector with an average LQ value of 0.50, it falls into the category of a potential sector in Quadrant III of the Klassen Typology due to its growth rate of 17.76 percent, which significantly exceeds the average growth rate of the reference region. Furthermore, a BSR value of 1.70 and an RIM value of 1.58 indicate that each one-unit increase in growth in the base sector is able to generate a substantial stimulus to non-base sector activities as well as an overall increase in regional income. This study concludes that despite the ongoing process of economic modernization, the agricultural sector in Depok City remains competitive.

Abstract

This study aimed to determine the phylogenetic relationship of coral trout groupers (Plectropomus spp.) in the waters of Liang Village, Banggai Kepulauan Regency, based on morphological characters. The research employed a descriptive exploratory method with quantitative and qualitative approaches. Samples were collected using purposive sampling, obtaining 15 individuals representing five species: Plectropomus leopardus, Plectropomus oligacanthus, Plectropomus maculatus, Plectropomus areolatus, and Plectropomus leavis. Morphological observations included 25 morphometric characters, 11 meristic characters, and 4 qualitative characters. Data were analyzed using Principal Component Analysis (PCA) to identify the main morphological characters contributing to variation among species, followed by cluster analysis using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) to assess phylogenetic relationships. The results indicated that the physicochemical conditions of the waters in Liang Village were suitable to support coral trout grouper populations. PCA results showed that the first two principal components (PC1 and PC2) explained 73.31% of the total morphological variation, with interorbital length, dorsal fin base length, and body depth contributing most significantly to species differentiation. The UPGMA dendrogram revealed that Plectropomus leopardus exhibited the closest phylogenetic relationship with Plectropomus areolatus and Plectropomus oligacanthus, while Plectropomus maculatus showed the greatest morphological divergence and formed a separate cluster. These findings demonstrate that morphological characters are effective in revealing phylogenetic relationships among Plectropomus species in the studied waters.

Abstract

This study aims to identify seagrass species found in the waters of Saleh Bay, Sumbawa Regency, and analyze the phylogenetic relationships between species based on morphological characteristics using a phenetic approach. The research was conducted from May to July 2025 at two observation stations, namely Gili Rakit and Gili Bakau. Sampling was carried out using purposive sampling with line transects, while species identification was based on observations of morphological characteristics including shape, size, leaf color, leaf tip and edge shape, root structure, and the presence of stem hairs. Morphological data were analyzed descriptively and then used in kinship relationship analysis using NTSYS version 2.02 software to produce a phenetic dendrogram. The results showed that five seagrass species were identified, namely Oceana serrulata, Cymodocea rotundata, Halodule uninervis, Halophila major, and Enhalus acoroides. Phenetic analysis showed consistent grouping between replicates within a species with a high degree of similarity, as well as clear separation of clusters between species. Oceana serrulata and Cymodocea rotundata show the closest kinship, while Enhalus acoroides is in the most separate cluster. These results indicate that morphological identification combined with phenetic analysis is effective in describing seagrass diversity and phylogenetic relationships, and can serve as an important basis for seagrass ecosystem management and conservation efforts in the waters of Saleh Bay.

Abstract

This research aims to determine the effect of NPK fertilizer, IBA, and GA3 on the vegetative growth of carrot plants (Daucus carota L.) in an aeroponic system. The study also employed a completely randomized design (CRD) with four treatments, namely control (P0), NPK 50 ml/L (P1), IBA 100 ml/L (P2), and GA3 25 ml/L (P3), each replicated three times. The observed parameters included plant height, stem diameter, number of leaves, root length, root surface area, and root volume. The results of the study showed that the application of NPK fertilizer had the most significant effect on vegetative growth, particularly in plant height, number of leaves, and root development, with an average increase of up to 50% compared to the treatments from the hormones. IBA hormone also plays a role in root formation and plant growth, while GA3 hormone increases plant height although with less influence compared to NPK and IBA. Thus, the aeroponics system combined with liquid NPK fertilizer has proven effective in supporting the vegetative growth of carrots.

Abstract

This study aimed to evaluate the effectiveness of palm sap (Borassus flabellifer L.) as an organic plant growth regulator on the vegetative growth of Dendrobium welirang orchids. Palm sap contains natural sugars, minerals, and biologically active components that may serve as an organic plant growth regulator. The research was conducted at the Candi Orchid Greenhouse in Semarang from July to October 2024 using a Completely Randomized Design with four palm sap concentrations, namely 0, 100, 150, and 200 ml/l, each applied in five replications. Observed parameters included plant height and root length. Data were analyzed using One Way ANOVA at a 5% significance level, followed by the Duncan Multiple Range Test. The results showed that palm sap concentration significantly affected plant height with the growth o1bserved in treatment P3 showing an average result of 12.01 cm. In contrast, root length was not significantly affected. These findings indicate that palm sap has potential as an environmentally friendly organic plant growth regulator to support vegetative growth of Dendrobium welirang orchids.

Abstract

This study aimed to evaluate the effect of pineapple peels combined with an aqueous infusion of dried coffee peels on the chemical and organoleptic quality of tepache and to determine the best proportion of both materials. The study employed a Completely Randomized Design (CRD) with four treatments and three replications consisting of variations of pineapple peels (F) and coffee peels (K): F1K1 (175 g:25 g), F2K2 (150 g:50 g), F3K3 (125 g:75 g), and F4K4 (100 g:100 g), with a total peel mass of 200 g and 3 days fermentation. Parameters analyzed included pH, total soluble solids, antioxidant activity, and organoleptic properties (color, aroma, and taste) evaluated by 25 panelists using a hedonic scale. The results showed significant effects on total soluble solids, antioxidant activity, and sensory attributes, but not on pH. The best treatment was F1K1, with antioxidant activity of 73.04 ppm and a taste score of 4.4. Tepache has the potential to be developed as a functional beverage based on food waste with added economic value.
