Household food security and nutrition are crucial determinants of public health, especially in regions with limited access to high-quality animal protein. This study aims to analyze the impact of organic chicken farming and maggot utilization on household food security and family nutrition in Jayapura, Papua. An exploratory case study with a mixed-method approach was used, involving observation, in-depth interviews, and documentation. The findings revealed that maggot-based feed significantly improved chicken growth, health, and egg production while reducing feed costs. Families experienced improved protein intake, reduced food expenditure, and additional income from the sale of eggs, maggots, and compost. Furthermore, the integration of maggot farming into organic poultry systems supported waste management and environmental sustainability through a circular economy model. This research implies that maggot-based organic farming can be replicated as a sustainable community food security strategy in similar regions across Papua and Indonesia.

Problems: Based on data from the Batam City Health Office, the 3 Community Health Centers with the highest incidence of anemia include Sei Panas 15.7%, Sambau 10.24%, Nongsa 8.24%. Objective: This study aims to determine the relationship between maternal age and parity with the incidence of anemia in pregnant women in the working area of UPT Puskesmas Sei Panas Batam City in 2024. Methods: This study used a descriptive correlation research design with a cross-sectional research design. The sampling technique used was Non Probability Sampling. Respondents in this study were 66 pregnant women. Results: Based on the Chi- Square test, the age variable obtained a P-value of 0.000 (ρ <0.05) and the parias variable with a P-value of 0.000 (ρ>0.05). This study shows that there is a relationship between age and the incidence of anemia in pregnant women and the relationship between parity and the incidence of anemia in pregnant women in the working area of UPT Puskesmas Sei Panas Batam City in 2024. Conclusion: there is a relationship between age and parity of mothers with the incidence of anemia in pregnant women. Suggestion: It is hoped that prospective mothers understand the ideal safe age and parity in preparing for a healthy pregnancy in order to avoid anemia during pregnancy. And pregnant women must be diligent in consuming Fe tablets and also make 6 ANC visits during pregnancy so that pregnant women's health is monitored, especially their Hb levels.

In addition to being programmatically successful in lowering TFR and slowing population growth rates, the Long-Term Contraceptive technique (MKJP) is an affordable technique of preventing conception. This study's objective was to examine variables associated with long-term contraceptive (MKJP) selection at the Gandasuli Community Health Center. The study design is cross-sectional and the research methodology is quantitative. The investigation was carried out in the workspace of the Gandasuli Community Health Center. 300 women of reproductive age made up the study's population, and a straightforward random selection procedure was used to choose 45 participants. A questionnaire was used to gather the data, which were then subjected to univariate and bivariate analysis using the Chi-Square statistical test. Age and MKJP choice did not correlate, according to the data (p- value = 0.09 > 0.05). The choice of MKJP was correlated with education (p-value = 0.003 < 0.05). The choice of MKJP was correlated with occupation (p-value = 0.003 < 0.05). The choice of MKJP and the husband's support are related, with a p value of 0.004 < 0.05. Parity and MKJP selection are related, with a p value of 0.003 < 0.05. Knowledge and MKJP selection are related, with a p-value of 0.003 < 0.05.

Abortion is one of the pregnancy complications that still contributes to maternal morbidity and mortality, especially in the early trimester of pregnancy. Various maternal factors play a role in the occurrence of abortion, one of which is parity which reflects a mother's reproductive history. This study aims to analyze the relationship between parity and the incidence of abortion at Bumi Panua Pohuwato Hospital. The study used a quantitative approach with observational analytical design and cross-sectional design. The study population was all pregnant women who received obstetrics services at Bumi Panua Pohuwato Hospital during the study period. Samples were taken using a total sampling technique, so that all pregnant women who met the inclusion criteria were included in the study. The independent variable is parity, while the dependent variable is the incidence of abortion. Data were obtained from medical records and analyzed univariately to describe the characteristics of respondents, and bivariously using Chi-square test or Fisher Exact Test in accordance with the fulfillment of statistical requirements. The results showed that most of the respondents were in active reproductive age and first to second trimester pregnancy, with considerable parity variations. Bivariate analysis showed that parity did not have a statistically significant relationship with abortion incidence. The conclusion of this study shows that the incidence of abortion is not influenced by parity alone, but is likely influenced by the interaction of various other maternal factors. Therefore, abortion risk screening in antenatal services needs to be carried out comprehensively by considering various pregnancy risk factors.

Background: Contraception is an effective method for controlling fertility and reducing the risk of unintended pregnancies. However, the utilization of long-term contraceptive methods remains relatively low. Several factors such as education level, parity, and age are believed to influence women’s decisions in choosing Contraception. Objective: This study aimed to analyze the influence of education, parity, and age on the use of Contraception. Methods: This study employed an analytical observational design with a cross-sectional approach. The sample consisted of 30 women of reproductive age selected using a total sampling technique. Data were collected through structured questionnaires and analyzed using the Chi-square test to determine the association between education, parity, age, and the use of Contraception. Results: The results showed a significant relationship between education level, parity, and age with the use of Contraception. Statistical analysis using the Chi-square test obtained a p-value of 0.003 (p < 0.05), indicating that education, parity, and age significantly influenced the use of long-term contraceptive methods. Conclusion: Education level, parity, and age have a significant influence on the use of Contraception. Improving health education and counseling regarding long-term contraceptive methods is essential to increase their utilization among women of reproductive age.

Postpartum depression is a mood disorder that occurs in mothers after childbirth, with symptoms that can appear from pregnancy until 4 weeks postpartum. This condition negatively impacts the psychological health of the mother and the development of the baby. This study aims to analyze factors associated with the risk of postpartum depression. The method used was quantitative with an analytical survey design through a cross-sectional approach. Data collection was carried out using the Edinburgh Postnatal Depression Scale (EPDS) questionnaire consisting of 10 questions. The results of the validity test showed a calculated r value of > 0.3610 and the reliability test obtained a Cronbach's alpha value of 0.67. The study sample consisted of 42 respondents selected using a total sampling technique, with inclusion criteria of mothers aged ≥18 years, in the period <6 weeks postpartum, and willing to be respondents. Data analysis used the chi-square test. The results showed that all variables had a significant relationship with the risk of postpartum depression (p < 0.05). These variables include age (p=0.040), education (p=0.018), occupation (p=0.011), history of depression (p=0.024), complications (p=0.017), economic status (p=0.048), parity (p=0.016), type of delivery (p=0.006), husband's support (p=0.000), and family support (p=0.028). Therefore, it can be concluded that demographic, obstetric, and social support factors play an important role in the risk of postpartum depression. These results are expected to form the basis for prevention efforts and early intervention to improve postpartum maternal mental health.

Modern retail expansion in Situbondo Regency has intensified competitive interaction with traditional markets, making it important to map differences in market structure, firm conduct, and performance outcomes. This study compares (i) market structure using concentration indicators (CR4 and the Herfindahl–Hirschman Index/HHI), (ii) competitive conduct (pricing practices, promotional intensity, service attributes, and relationship patterns), and (iii) performance proxies (sales turnover and selected price efficiency measures) within the SCP framework. The analysis applies a descriptive quantitative approach supported by targeted primary observations and questionnaire-based information, and complemented by official statistics and regulatory documents. Traditional-market samples include Panji, Besuki, and Panarukan markets, while modern-retail samples include local outlets of Indomaret, Alfamart, and Basmalah. Results indicate that traditional markets are relatively unconcentrated (CR4 = 38.0%; HHI = 744), consistent with a competitive structure dominated by many small vendors. Modern retail is more concentrated (CR4 = 77.0%; HHI = 1,644), suggesting moderate concentration and a tendency toward local oligopoly. Average monthly turnover per unit is higher for modern retail (IDR 36.36 million) than for traditional vendors (IDR 15.63 million). Price efficiency varies across commodities: some items show near parity, while several fresh commodities remain cheaper in traditional markets. Policy implications point to balanced local governance: zoning and permitting for modern stores, continuous revitalization of traditional markets, and strengthened MSME partnership schemes to ensure healthy and inclusive competition.
