Abstract

The giant honeybee (Apis dorsata) is vital for ecosystems as a pollinator, significantly impacting agricultural productivity, biodiversity, and food sustainability. This study explores the morphometric characteristics of Apis dorsata populations in Batu Rakit Village, North Lombok Regency, a tropical region with rich biodiversity. Morphometric data were collected from 20 worker bees, focusing on body length, abdomen dimensions, wing dimensions, proboscis length, and body weight. Measurements were analyzed using descriptive statistics, correlation, and regression to identify significant relationships between morphometric traits and body weight. Results show that abdomen length (r = 0.50, β = 0.05, p = 0.01) and forewing length (r = 0.48, β = 0.08, p = 0.03) are the strongest predictors of body weight, underscoring their roles in resource storage and flight efficiency. Most traits exhibited low variability, reflecting evolutionary adaptations to environmental stability, while body weight displayed high variability (CV = 7.53%), indicating responses to environmental and individual factors. These findings highlight the ecological importance of uniform traits such as abdomen length and wing dimensions in supporting the foraging efficiency and resource transport of Apis dorsata. This study provides critical insights for the conservation and management of Apis dorsata populations in tropical ecosystems.

Abstract

Urinary Tract Infection (UTI) is a common health issue among women, including those caused by the use of menstrual pads. This study aims to investigate the difference in the incidence of UTI between women using herbal and non-herbal pads at Prodia Clinical Laboratory in Palembang. This research employed an analytical observational design with 31 female employees as subjects. Sampling was conducted using a questionnaire and complete urine tests, including dipstick and microscopic examination. The results showed that 10.5% of non-herbal pad users were suspected of having UTI, while no herbal pad users were suspected of having UTI. Based on the Mann Whitney U statistical test, no significant differences were found between the two groups (p > 0.05). This study concluded that there is no significant difference in the incidence of UTI between users of herbal and non-herbal pads. Further research with a larger sample size is recommended to confirm these findings.

Abstract

Tympanic membrane perforation and continuous discharge are hallmarks of chronic suppurative otitis media, a chronic inflammation of the middle ear. Through the malfunction of the Eustachian tube brought on by allergic inflammation, allergic rhinitis may contribute to the development of CSOM. This study aimed to analyze the relationship between allergic rhinitis and CSOM, identify common allergens, and assess the association between eosinophil levels and CSOM. A case-control study was conducted at RSUP H. Adam Malik and RS Murni Teguh Medan involving 72 participants: 36 CSOM patients and 36 healthy controls. Skin prick tests (SPT) and eosinophil counts were used to assess allergic status. Statistical analysis used Chi-square and Fisher’s exact test with significance set at p < 0.05. The results showed a significant association between allergic rhinitis and CSOM (p = 0.001; OR = 6.192). Common allergens found in CSOM patients were D. pteronyssinus (66.7%), D. farinae (63.9%), and cockroach (47.2%), with significant associations (p < 0.05). No significant relationship was found between allergic rhinitis and CSOM sides or type (p > 0.05). Elevated eosinophil levels were more common in the CSOM group but were not statistically significant (p = 0.624). In conclusion, allergic rhinitis is significantly associated with CSOM. Allergen screening is recommended for CSOM patients to improve diagnosis, treatment, and recurrence prevention.

Abstract

The Bukit Manjai Valley Tropical Rainforest Park is home to an abundance of plants that includes a host of Ficus species. The objective of this study was to inventory and descriptively account for the Ficus present in the park. The purposive sampling method was used, where any time we found a Ficus plant, the data collection occurred. Upon finding a Ficus plant, we documented it with photographic evidence and provide scientific identification along with measurements for environmental parameters including air temperature, air humidity (RH), light intensity, soil pH, altitude elevation, soil moisture, and wind speed. The study identified five species of Ficus, specifically, Ficus fistulosa Reinw. Ex Blume, Ficus montana Burm.f., Ficus rosulata C.C.Berg, Ficus uncinata (King) Becc and, Ficus variegata Blume. The study results suggest that the environmental conditions in Bukit Manjai Valley Tropical Rainforest Park, are very conducive for the growth and survival of a variety of Ficus species. This inventory study provides important information to aid the understanding of biodiversity, especially of the Ficus genus, in the tropical rainforest ecosystem of Borneo.

Abstract

The increasing problem of the electrical energy crisis encourages the need for efforts to develop environmentally friendly energy sources, for example, MFC. MFC using a consortium of thermophilic bacteria can provide advantages because it increases the reaction kinetics on the anode which contributes to the performance of the fuel cell. This study aims to optimize the concentration of thermophilic bacteria consortium as a starter in MFC. This study used thermophilic bacterial consortium MS 12 and MS 18 isolates from Mudik Sapan hot spring, and tested five different starter concentrations (3%, 6%, 9%, 12%, and 15%). The bacterial cultures were fermented in a two-chamber bioreactor of the MFC system with voltage measurements every 2 hours for 24 hours. Results showed the 9% concentration produced the highest average voltage output of 0.8043 V, indicating optimal electrogenic performance. This study highlights the important role of starter concentration in improving MFC efficiency.

Abstract

Cucumber (Cucumis sativus L.) is a high-value horticultural crop widely used as fresh vegetables, processed food ingredients, and cosmetic products. In addition, cucumber contains important nutrients for health, such as vitamin C, vitamin K, and various essential minerals. As a plant with many benefits, cucumber is greatly influenced by climatic conditions, which can directly affect productivity and harvest quality. Based on this, a study on the phenology of cucumber plants under two different climatic conditions was conducted. This study used an experimental method involving 20 cucumber plants, with two location treatments and two replications. The observed parameters included the time of flower emergence and flowering duration. The study was conducted from September to December 2024 at two locations, Kamang Magek and Padang. The data were analyzed using a t-test with a significance level of 5%. The results of the study showed significant phenological differences between cucumber plants grown in Kamang Magek and Padang. Plants in Kamang Magek went through generative phases earlier, marked by earlier flower emergence, which occurred on day 25.4 after planting, compared to day 29.45 in Padang. The flowering duration in Kamang Magek was also shorter, lasting 7.9 days, compared to 10.55 days in Padang. These findings indicate that differences in climatic conditions between the two locations have a significant impact on the phenological development of cucumber plants.

Abstract

Channa striata, commonly known as snakehead fish is a freshwater species with significant economic value. The high commercial value of this fish is attributable to the albumin content in the flesh of snakehead fish. The elevated cost of fish meal constitutes a significant challenge for fish farmers, given its role in fish feed formulations. Consequently, an alternative feed substitution that is both inexpensive and reduces the use of fish meal is required. The purpose of this study was to analyse the performance of feed formulations with the use of egg hatchery waste meal as a source of protein in snakehead fish. The research method utilised a completely randomised design (CRD), incorporating five distinct treatments and three replicates. The treatments in this study were P1 (0% hatchery waste meal/100 %  fish meal), P2 (25% hatchery waste meal + 75%  fish meal), P3 (50% hatchery waste meal + 50 fish meal), P4 (75% hatchery waste meal + 25% fish meal) and P5 (100% hatchery waste meal).  The utilisation of hatchery waste meal as a feed substitute in snakehead fish feed has been demonstrated to exert a significant effect including absolute growth rate, EPP, SGR and FCR. However, it has been observed that this substitution does not compromise the survival rate of snakehead fish. The incorporation of 25%  hatchery waste meal resulted in the optimal absolute weight growth rate and specific growth rate of snakehead fish, which were 4.32 g and 3.13%, respectively.

Abstract

Propolis, which is produced by Tetragonula sp., has the potential to treat a number of illnesses, including microbial infections, wounds, depression, and cancer. However, in order for propolis to be used as a raw material for traditional medicine, it must be standardized. The goal of this study was to standardize the values of specific and non-specific parameters. Propolis was extracted using the maceration method with 70% ethanol solvent until a thick extract was obtained, and the thick extract was tested for both specific and non-specific parameters. In terms of specific parameters, the obtained extract is a thick yellowish-brown liquid, has a characteristic sour propolis scent, and is sticky. Phytochemical screening also showed that the extract was positive for flavonoids, phenolics, alkaloids, saponins and tannins. Meanwhile, the nonspecific test obtained a drying shrinkage value of 35.059%, moisture content of 33.698%, specific gravity of 1.0082 g/ml, and total ash content of 1.26%. The results of the specific and nonspecific parameter tests have met the established extract requirements. Further quantitative identification of the activity of compounds in propolis is recommended for the development of traditional medicine.

Abstract

Tomato (Solanum lycopersicum L.) is one of the horticultural commodities with high economic value whose growth is greatly influenced by environmental conditions. This study aims to examine the phenology of tomato plants, including the time of flowering and flowering duration in different environmental conditions as a basis for developing more effective cultivation techniques. The study was conducted in two locations, namely Kamang Magek District and Padang City, with 20 replications per location. Phenology observations were carried out on the time of flowering and flowering duration of tomato plants, and the data obtained were analyzed using the t-test at a significance level of 5%. The results showed a significant difference between the two locations, where the average time of flowering in Kamang Magek District was 38.5 days after planting (DAP) with a flowering duration of 10.85 days, while in Padang City the time of flowering occurred at 75.8 DAP with a flowering duration of 30.3 days. This difference indicates that environmental conditions in Kamang Magek District are more supportive of accelerating the flowering phase with a shorter flowering cycle.
