Abstract

Noise generated by human activity is a form of environmental disturbance that has the potential to affect wildlife behavior, including birds that rely heavily on acoustic communication for their daily activities. This study aims to analyze the influence of human noise on bird activity and behavior in the coastal area of ??Sejarah Beach, Batubara Regency, North Sumatra. This study used a qualitative approach with descriptive methods through direct field observations from January 28 to February 2, 2026. Data were collected through observations of bird activity and human activity around the observation area, such as visitor conversations, footsteps, and other tourist activities that produce sound. The results of the observations indicate that birds engage in various activities, such as foraging, resting, and grooming, when the environment is relatively quiet. However, increased human activity that produces noise causes birds to increase their vigilance and move to quieter areas. This suggests that anthropogenic noise can affect bird behavior patterns and habitat utilization in coastal areas. Therefore, the application of environmental management principles and wildlife observation ethics is necessary to minimize disturbances to natural bird activities and support conservation efforts in coastal areas.

Abstract

The development of biotechnology through plant tissue culture techniques provides significant benefits in producing superior, disease-free seedlings quickly. However, the use of modified Murashige and Skoog (MS) media also produces laboratory waste that has the potential to pollute the environment if not managed properly. This study aims to examine the management of tissue culture media waste, identify potential risks, and analyze the application of bioethical principles in its management. This study uses a descriptive qualitative approach with data collection techniques through observation and documentation in the Tissue Culture Laboratory. The results show that contaminated culture media waste is still disposed of directly without undergoing a sterilization process and waste separation according to standards. This condition has the potential to cause negative impacts such as the spread of microorganisms, environmental pollution due to chemical content, and the risk of health problems. From a bioethical perspective, this practice does not fully implement the principles of non-maleficence, beneficence, and responsibility. Therefore, the implementation of waste management in accordance with bioethical principles through sterilization, waste separation, and sustainable management is needed to support safe and responsible laboratory practices.

Abstract

This study aims to analyze the cleanliness and design of laying hen cages and their relationship to disease prevention and livestock welfare from an ethical and bioethical perspective. The method used was a descriptive study with direct observation and interviews conducted at a laying hen farm in Simalungun Regency, North Sumatra. Observed aspects included cage height, distance between chickens and manure, manure removal system, ventilation, and general cleanliness of the cage. The results showed that the cage conditions generally met good standards, with a cage height of approximately 2.5 meters, natural ventilation supporting air circulation, and cage cleanliness maintained through routine cleaning every three days. Adequate distance between chickens and manure and a low fly presence also indicated a relatively low risk of disease transmission. Furthermore, regular use of disinfectants helped control pathogenic microorganisms. From an ethical and bioethical perspective, the husbandry practices implemented reflect the farmer's moral responsibility to maintain animal welfare by providing a clean, healthy, and appropriate environment. However, this study is still limited to a single location and is descriptive in nature, so further research with a broader scope and a quantitative approach is needed.

Abstract

Accurate determination of life insurance premiums requires mortality data that is representative of the characteristics of the insured population. This study aims to analyze the mortality patterns of the Indonesian population based on ASDR data from the SP2020 of the Central Statistics Agency, and apply it in estimating net premiums for term life insurance. The methods used include converting ASDR to probability of death (qx), reconstructing a 5-year abridged life table for productive ages 25–60 years, calculating the actuarial present value (APV) of death benefits, life annuity due, and net premiums based on the actuarial equivalence principle. The discount rate used is 5% with a sum insured of Rp100,000,000 and a policy term of 10 years. The results show that the qx value is relatively constant at 0.00264 in the age range of 25–46 years, then increases significantly to 0.02610 at age 60. The annual net premium for ages 25–46 years is recorded as stable at Rp251,428.57 and increases sharply to Rp467,838.75 at age 49. This study contributes to providing the first publicly accessible proxy life table from the 2020 Population Census aggregate data as an alternative to the Indonesian Mortality Table (TMI).

Abstract

Red chili (Capsicum annuum L.) is a horticultural commodity with high economic value in Indonesia, but its productivity has not yet reached its optimal potential. One important factor in increasing productivity is the use of quality seeds with high viability and vigor. This study aims to evaluate the role of chili seed innovation through a critical thinking approach and the application of bioethical principles in horticultural development at the Medan Horticultural Seed Development Unit (UPT). This study emphasizes the importance of applying the principles of benefit, non-maleficence, autonomy, and justice in the process of testing seed moisture content and germination. The results of the study indicate that seed innovation accompanied by the application of bioethics can improve seed quality while maintaining moral responsibility towards farmers, consumers, and the environment. Thus, chili seed development based on bioethics is an important strategy in realizing sustainable and competitive horticulture.

Abstract

This study aims to map poverty levels based on sub-districts in the City of Medan using a descriptive quantitative approach and spatial analysis. The data used consists of population numbers, the number of poor people, and poverty percentages in 21 sub-districts in 2023, obtained from the Medan City BPS. Analysis was conducted through descriptive statistics, Natural Breaks (Jenks) classification, and choropleth map visualization. The results of the study show that the average poverty level in Medan City is 10.10% with a clear spatial clustering pattern. Northern areas such as Medan Belawan, Medan Labuhan, Medan Marelan, and Medan Deli have high to very high poverty levels, while central and southern areas tend to be lower. These findings indicate spatial disparities between regions and can serve as a basis for more targeted poverty alleviation policies.

Abstract

This study compares the calculation of net single premium of endowment life insurance between discrete annuity and continuous annuity approaches using Select and Ultimate Table. Mortality data used is 2015 CSO Male Non-Smoker ANB (Age Nearest Birthday) which has gone through a pre-processing process, including the value of k?[x] for the entry age range of 20 to 50 years. Calculations are performed on four policy terms, namely 10, 15, 20, and 25 years, assuming a single interest rate i = 5% per year. The continuous approach uses the Uniform Distribution of Deaths (UDD) approximation. The results show that the average absolute difference between the two methods ranges from 0.000083 (n = 10) to 0.000559 (n = 25), while the average relative difference ranges from 0.0135% (n = 10) to 0.1804% (n = 25). The differences increase with increasing entry age and policy term, but all values ??are well below the 1% actuarial materiality threshold. This finding indicates that both approaches can be used interchangeably within the age and term ranges studied, with the caveat that generalizing the results beyond these parameters requires further study.

Abstract

This study aims to analyze the implementation of qualitative research methodology in uncovering the principal's transformational leadership practices and their contribution to strengthening educational management at SMA Negeri 1 Sosopan, Padang Lawas Regency. The study used a qualitative approach with a case study design. Informants were selected purposively, including the principal, vice principal, teachers, and education staff. Data were collected through in-depth interviews, observations, and documentation studies, then analyzed using the interactive model of Miles, Huberman, and Saldaña through data condensation, data presentation, and conclusion drawing. Data validity was guaranteed through source triangulation, technical triangulation, and member checking. The results showed that the qualitative research methodology was able to comprehensively uncover transformational leadership practices that include idealized influence, inspirational motivation, intellectual stimulation, and individual attention. These four dimensions contribute to strengthening educational management through building trust, unifying organizational vision, developing an innovative culture, and empowering human resources. This study confirms that a qualitative case study-based approach is effective in producing an in-depth, contextual, and empirical understanding of transformational leadership as a basis for strengthening participatory, adaptive, and sustainable educational management.
