Abstract

Birds have a vital ecological role as pollinators, seed dispersers, and insect population controllers. Their diversity is super important in ecology and conservation studies. This study aims to identify and analyze the bird community structure in the Special Purpose Forest Area of Muhammadiyah University of Mataram. Field surveys were conducted in June 2025 using the point count method at four observation points selected through purposive sampling. Observations were carried out over three time periods with two repetitions at each point. The study recorded 26 bird species from 23 families, totaling 177 individuals. Dominant species included Pycnonotus goiavier, Orthotomus sepium, and Todiramphus chloris. Additionally, endemic species of Nusa Tenggara such as Otus jolandae and Pitta concinna were recorded. Ecological analysis showed a Shannon-Wiener diversity index of 2.99, a Margalef species richness index of 4.83, and an Evenness index of 0.92. These values reflect a stable, healthy bird community with an even distribution of individuals without the dominance of any particular species. Based on these findings, this study recommends strengthening conservation efforts through the preservation of natural vegetation, regular monitoring of bird populations, and further research.

Abstract

The asian moon scallop (Amusium pleuronectes) is a high-value fishery commodity and serves as a natural bioindicator of water quality due to its filter-feeding behavior. This research aimed to analyze Escherichia coli contamination in scallop products from Lampung Bay as an indicator of microbiological and environmental conditions. Testing was conducted at the Microbiology Laboratory of UPTD PMHP, Lampung Province, using the Indonesian National Standard (SNI) 2332.1:2015. The presumptive test using Lauryl Tryptose Broth (LTB) showed five positive tubes: three at 10⁻¹, one at 10⁻², and one at 10⁻³ dilution. However, confirmatory tests using Brilliant Green Lactose Bile Broth (BGLB), EC Broth, and L-EMB Agar all showed negative results for E. coli, with a Most Probable Number (MPN) value of <3 MPN/g. Environmental quality assessment indicated that physicochemical parameters complied with marine water quality standards. The pH ranged from 7.8–8.0, temperature was 27–30°C, salinity ranged from 30–34 ppt, and DO was >5 mg/L. The results demonstrate that the scallop products are microbiologically safe and that the surrounding waters meet environmental quality standards, supporting sustainable shellfish cultivation. Routine monitoring, enhanced waste management, and fortified bioindicator-based assessments are recommended to ensure long-term food safety and environmental sustainability in coastal regions.

Abstract

Waste management issues in Indonesia are a major concern due to the high volume and poor management systems in many Final Processing Sites (TPAs). This study aims to analyze the impact of the expansion of the Ijobalit Landfill in East Lombok Regency on the environment and social dynamics of the surrounding community. The research uses a qualitative approach with an embedded single case study design. Data was collected through field observation and in-depth interviews, then analyzed using NVivo 12 Plus software. The results showed that the expansion of the landfill was carried out without meeting the operational standards (SOP) and SNI, causing various negative impacts, such as water and air pollution, declining the quality of agricultural land, health problems, and social unrest in the community. Economically, landfills do not make a significant contribution to the welfare of the community. The conclusions of this study emphasize the importance of sustainable and participatory landfill management. This study recommends the need for ecological and social-based waste management policies, involving communities in every stage of planning and decision-making.

Intradialysis complications such as hypotension and intradialysis hypertension are one of the abnormal conditions that occur during the hemodialysis process. The purpose of this study in RSUD Praya was to evaluate the relationship between IMT, hemoglobin level, and duration of hemodialysis with changes in blood pressure during the hemodialysis process. This study used a cross-sectional approach and was observational quantitative analytic in nature. Sampling was done using the total sampling method. The sample size of this study was 45 samples. Data were tested using spearmen rank. The findings of 45 respondents, most of them have stable blood pressure 24 people (53.3%), while 10 people (22.2%) have decreased blood pressure, and 11 people (24.4%) have increased blood pressure. There was a significant correlation between body mass index and blood pressure changes (p=0.028). Hemoglobin levels were not associated with blood pressure changes (p=0.574). There was a strong relationship between hemodialysis duration and blood pressure changes (p=0.009). There is a relationship between BMI, duration of hemodialysis and blood pressure changes during hemodialysis process and there is no relationship between hemoglobin levels and blood pressure changes during hemodialysis process. The conclusion is that body mass index and duration of hemodialysis affect blood pressure changes in hemodialysis patients at Praya Regional Hospital, while hemoglobin levels have no influence on blood pressure changes in hemodialysis patients at Praya Regional Hospital.

Abstract

Type 2 diabetes mellitus is a chronic condition with hyperglycemia due to insulin resistance and impaired insulin secretion, where oral medication non-compliance can worse glycemic control and trigger inflammation characterized by elevated hs-CRP levels. This research aims to examine the relationship between compliance with oral hypoglycemic drugs and hs-CRP levels in patients with diabetes mellitus. This study used a cross-sectional design with purposive sampling of 20 patients with type 2 diabetes mellitus at Puskesmas Mojolaban. Compliance was assessed by MARS-10 and hs-CRP levels were measured by immunoturbidimetry, then analyzed by descriptive statistics and correlation with Fisher’s Exact Test. The results showed that 95% of respondents who adhered to their medication had normal hs-CRP levels (<0.85 mg/L), while 5% of non-adherent respondents had abnormal hs-CRP levels (>0,85 mg/L). The Fisher’s Exact Test result in a p-value = 0.050, indicating a significant relationship between compliance with oral hypoglycemic drugs and hs-CRP levels. Compliance to oral medication in patients with type 2 diabetes mellitus may be an effective strategy to suppress systemic inflammation (hs-CRP) and prevent macrovascular compliactions.

Abstract

Acclimatization represents a critical transition phase in ex-situ conservation of tropical orchids, marking the shift from sterile in vitro conditions to more variable external environments. This literature review aims to synthesize recent experimental findings on the influence of abiotic and biotic factors on seedling viability and to propose an effective acclimatization protocol. A systematic analysis was conducted on over 30 peer-reviewed articles published between 2014 and 2024, covering media formulation, substrate selection, environmental controls, and microbial inoculation. The results highlight that optimized substrates such as moss, coconut fiber, and carbonized rice husk significantly improve root aeration and water retention. Supplementation with organic additives (e.g., peptone, coconut water, banana pulp) enhances early seedling vigor when applied to modified Murashige and Skoog (MS) media. Environmental parameters especially light intensity, diurnal temperature fluctuation (DIF), humidity, and photoperiod directly affect physiological responses. Moreover, inoculation with plant growth-promoting bacteria (PGPB) and mycorrhizal fungi contributes to phosphate solubilization, nitrogen fixation, siderophore production, and stress tolerance. In conclusion, the integration of species-specific abiotic and biotic strategies enhances survival and growth, offering scalable potential for orchid conservation and commercial propagation. It is recommended that future research focus on long-term physiological assessments and standardized inoculant formulations to improve protocol consistency across diverse orchid taxa.

Abstract

Limited fertile land encourages the use of subsoil for oil palm nurseries, despite its low organic matter content and dense structure. This study aims to examine the effect of bokashi varieties on the growth of oil palm seedlings in different soil layers. The study was conducted at KP2 Instiper Yogyakarta, Kalikuning Village, Maguwoharjo, Sleman, from January 15 to April 15, 2025 using a completely randomized design (CRD) with two factors, namely bokashi varieties (NPK control, sugarcane filter cake bokashi, water hyacinth, and LCC) and soil layers (topsoil and subsoil Regosol soil), with a mixing ratio of 1:1. Each treatment combination was repeated five times with a total of 40 seedlings. Data analysis was carried out through analysis of variance, followed by the DMRT test at a significance level of 5%. The results showed a significant interaction between bokashi varieties and soil layers on fresh and dry root weight, where all bokashi showed better results than the NPK control, with water hyacinth bokashi as the best. In conclusion, the use of bokashi, particularly from water hyacinth, can enhance the root growth of oil palm seedlings. These findings recommend the use of local organic materials as an alternative fertilizer for marginal subsoil.

Abstract

Severe hyperglycemia symptoms can be brought on by elevated blood glucose levels. Diabetes mellitus will result if this occurs consistently over a period of years. The aim of this study was to determine the effects of breadfruit leaf extract on blood glucose reduction and the effects of alloxan on mice's weight. Data analysis using ANOVA at 5% confidence interval and LSD (Least Significant Difference) test. The research results showed that the K+ group (which was only induced by alloxan) experienced a significant decrease in blood glucose levels when breadfruit leaf extract was administered. Blood glucose level of mice was found to decrease by 61% (87.60 ± 1.07) at an effective dose of 22.4 mg/grbw/day (P3), which was almost the same as the blood glucose level of K (-) on day 0; in addition, the body weight of mice increased after a hyperglycemic episode when the ethanol extract of breadfruit leaves was administered.
