Analisis Model SITR dengan Tes Viral Load Pada Penyebaran Penyakit HIV di Indonesia
No full textHuman Immunodeficiency Virus (HIV) is a virus that attacks white blood cells in the body. Until now, HIV is still one of the world's health problems. Mathematical models have an important role in understanding the dynamics of a disease epidemic. The purpose of this study is to model and analyze the spread of HIV disease in Indonesia using the SITR model with viral load tests. This model divides the population into four subpopulations, namely Susceptible (S) or subpopulations that are susceptible to contracting the disease, Infected (I) or subpopulations that are infected with HIV, Treatment (T) or subpopulations that are infected with HIV and receive ARV treatment, and Recovery (R) or subpopulations whose viral load test results are suppressed after taking ARV treatment. The model analysis was conducted with model assumptions, parameter estimation, equilibrium point determination, equilibrium point stability analysis, and numerical simulation using Maple18. Based on the analysis, the value of =10,52749285 is obtained, which means that the model is asymptotically stable towards the endemic equilibrium point.

Pola Adaptasi Masyarakat Terhadap Banjir Pasang Surut (ROB) di Kecamatan Penjaringan, Kota Jakarta Utara
No full textTidal flooding increasingly affects low-lying coastal areas in North Jakarta, particularly Penjaringan District, where recurrent inundation disrupts settlements, infrastructure, and livelihoods. This study analyzes the spatial distribution of tidal flood-prone areas, identifies key factors influencing community adaptation, and examines prevailing adaptation patterns. Employing a descriptive quantitative approach integrated with spatial analysis, primary data were gathered through field observations, structured interviews, and questionnaire surveys in Pluit and Penjaringan subdistricts, supplemented by secondary data for mapping and hazard assessment. Descriptive analysis evaluated internal factors like socio-economic characteristics, residence duration, and risk awareness, alongside external factors such as environmental conditions and infrastructure. Highest flood exposure in low-elevation, high-density areas near the coast. Communities adapt via physical, economic strategies for livelihood continuity, and social responses like collective action. These enhance short-term resilience but face constraints from limited resources and environmental pressures. Community-based adaptation reduces vulnerability, yet requires stronger integration with spatial planning and coastal policies for sustainable risk reduction

Pengaruh Attitude Toward Behavior dan Change Mechanisms terhadap Pengambilan Keputusan Vasektomi pada Suami
No full textDecision making on contraceptive use is actually not only the responsibility of women, but also a shared responsibility with their husbands. It is important to understand the factors that influence husbands' decisions in using contraceptives, one of which is attitude towards behavior. The mechanism of attitude change is also very important to understand, because it can affect changes in husbands' contraceptive decision making. This study aims to identify how attitudes towards contraception affect the husband's decision-making process, as well as the role of attitude change mechanisms in shaping their involvement in family planning choices. This study is a quantitative study with a cross-sectional approach. The sampling technique was carried out randomly with multistage random sampling. The sample in this study was calculated based on the Yamahen formula so that 110 respondents were obtained. The results of this study indicate that husbands' attitudes towards contraception significantly influence their decision-making process regarding contraceptive use. Positive attitudes towards contraception are associated with greater involvement in decision making and a higher likelihood of using contraception. Attitude change mechanisms, such as information from health care providers and discussions with partners, play an important role in changing husbands' perspectives, which ultimately lead to more supportive decisions regarding family planning. These findings highlight the importance of targeting attitude change in interventions aimed at increasing community participation in conservation decision-making.Background: Decision making on contraceptive use is actually not only the responsibility of women, but also a shared responsibility with their husbands.
