Hyperspectral unmixing is a fundamental task in remote sensing that aims to decompose mixed spectral pixels into their constituent materials and estimate their respective abundances. Traditional methods often face limitations due to nonlinear mixing effects and the lack of pure pixels. This paper proposes a deep learning-based comparative framework that integrates modified versions of the Minimum Simplex Convolutional Network (MiSiCNet) and Unsupervised Deep Image Prior (UnDIP), referred to as Blind MiSiCNet and Supervised UnDIP, respectively, to achieve robust unmixing and abundance estimation in real-world scenarios. The proposed Blind MiSiCNet removes downsampling and upsampling layers and leverages spatial and geometric priors through convolutional layers with a minimum simplex volume constraint, producing reliable initial abundance maps even in the absence of pure pixels. The Supervised UnDIP variant further refines these estimates using the implicit regularization of convolutional neural networks, incorporating known endmembers to generate noise-free and spatially coherent abundance maps. Experimental results on the real-world Jasper Ridge dataset demonstrate that the proposed supervised and blind unmixing methods, evaluated comparatively, significantly outperform existing approaches regarding Spectral Angle Distance (SAD) and Root Mean Square Error (RMSE). The results also highlight improved noise robustness and better preservation of spatial structures.

This research discusses the increasing child violence in Bintan Regency every year. The purpose of this research is to analyze the implementation of collaborative governance in addressing violence against children. The research uses a descriptive qualitative method with data collection techniques through observation, interviews, and documentation. The theory used is the collaborative governance theory by Ansell & Gash, which consists of five indicators: face to face, trust building, commitment to process, shared understanding, and intermediate outcomes. The conclusion of this research shows that collaborative governance in addressing child violence in Bintan Regency has been implemented, with collaboration between the government, child protection agencies, and the community. The indicators of face to face, trust building, and shared understanding have been quite good through communication and coordination among the actors. However, the indicators of commitment to process and intermediate outcomes still face challenges such as changes in positions, sectoral egos, and time constraints. Although services for victims have started to improve, the rate of child violence remains high and many cases are resolved peacefully. An increase in commitment and coordination is needed to strengthen protection efforts and elevate the status of Child-Friendly Districts.

Tuberculosis (TB) is the ninth leading cause of death worldwide, surpassing HIV/AIDS. In 2016, TB-related deaths among HIV-negative individuals reached 1.3 million, while deaths among those with HIV-TB co-infection totaled 374,000. Indonesia ranks among the top five countries with the highest TB burden, accounting for approximately 5.8% of global TB cases. The TB prevalence rate in Indonesia in 2016 was 391 per 100,000 population, with nearly half of the cases occurring among women of reproductive age. It is estimated that 1–3% of pregnant women have TB, and some are also co-infected with HIV. The national target for TB elimination by 2030 is to reduce incidence to 65 per 10,000 population and mortality to 6 per 100,000 population. However, in Mimika District, the TB incidence remains high at 707 per 10,000 population, with a mortality rate of 27 per 100,000 population.This community service program aimed to improve knowledge regarding the prevention of pulmonary TB transmission from adults to toddlers living in the same household, in order to break the chain of transmission. The activity was conducted from July to September 2024 in Kamoro Jaya Subdistrict, under the jurisdiction of Wania Health Center, with 90 participants consisting of mothers with toddlers and community health volunteers (Posyandu cadres).Methods used included lectures, group discussions, and demonstrations. The educational material focused on the prevention of TB transmission in children. Participants completed a questionnaire before the activity. The results showed an increase in knowledge regarding the prevention of pulmonary TB in children.

The quality of human resources is an important aspect in regional development, which is reflected through the Human Development Index (HDI). HDI is influenced by various factors, including the economic conditions and education of the community. This study aims to analyze the effect of Gross Regional Domestic Product (GRDP) per capita and Average Length of Schooling (RLS) on HDI in South Kalimantan Province. The data used comes from the Central Statistics Agency (BPS) with a coverage of 13 regencies/cities during the period 2018 to 2023. The analysis method used is multiple linear regression with the help of R Studio software. The results of the study show that both GRDP per capita and RLS have a significant effect on HDI, both simultaneously and partially. The resulting model has an adjusted R² value of 0.8627, which indicates that 86.27% of the variation in HDI can be explained by these two variables. The classical assumption test including linearity, conditional zero error expectation, absence of multicollinearity, autocorrelation, homoscedasticity, and residual normality shows that the model used has met all the criteria as the Best Linear Unbiased Estimator (BLUE). Thus, this regression model is valid for use in estimating and making inferences on the factors that influence the HDI in South Kalimantan Province. This finding confirms that increasing education and economic growth are strategic steps in accelerating human development in South Kalimantan.

Not many studies have examined differences in anxiety in facing the world of work based on gender, specifically in vocational students. Previous research has conducted several studies on anxiety in vocational students. The purpose of this study is to determine the differences in the level of anxiety of vocational students towards the world of work based on their gender. The number of samples in this study was 233 students, of which 173 were male and 60 were female. This study uses a descriptive quantitative approach, with a disproportionate stratified random sampling technique and anxiety scale used to collect data. Data processing in this study uses a normality test and homogeneity test, and data analysis using a T-test by applying IBM SPSS Statistics software version 25. The results of data analysis in the T-test show a significance level value of .737(>.05), which means that there is no difference in the level of anxiety in vocational school students in facing the world of work based on gender, which means H0 is accepted, and H1 is rejected. The results of our study indicate that gender-based anxiety in the world of work in men emphasizes the abilities they have while women emphasize feelings.

This study aims to analyze the effect of work motivation and compensation on employee performance at Percetakan Sewelas Triwulan.

Additionally, compensation has a significant influence on employee performance, with a regression coefficient of 0.58 (p < 0.05). Simultaneously, both motivation and compensation have a significant impact on employee performance, with an F-value of 8.45 (p < 0.05). The implications of this study underscore the importance of management enhancing work motivation through non-financial rewards and ensuring fairness in compensation, thereby creating a productive work environment that supports optimal employee performance.

Doom spending is often conceptualized as a form of mental problem wherein individuals seek temporary relief or satisfaction through impulsive consumption in response to mental distress. This study examines the phenomenon of doom spending within the framework of mental health and Islamic ethical teachings. Employing a qualitative approach, this research adopts a descriptive-analytical method based on a comprehensive literature review of prior studies encompassing psychological, sociocultural, and religious perspectives. Thematic analysis is utilized to identify meaning patterns and explore the correlation between consumptive behavior and Islamic ethical principles. Findings indicate that doom spending not only undermines an individual's financial stability but also aggravates psychological well-being. Islamic teachings emphasize the importance of self-restraint, gratitude (shukr), and detachment from material excess (zuhd). Islam advocates for the pursuit of inner tranquility through worship, self-reflection (mu??sabah), and responsible financial conduct—reminding individuals that lasting happiness does not stem from fulfilling excessive worldly desires but from spiritual contentment and ethical living.

Ghost stories are part of the culture that plays a role in shaping adolescents' understanding and perception of the immaterial world. However, culture and the role of digital media can also influence adolescents' understanding and perception. This study aims to determine the perception of ghosts in adolescents and understand the subjective experiences of late adolescents (aged 17–19 years) in forming these perceptions. This study employed a qualitative approach with a phenomenological method with Interpretative Phenomenological Analysis data analysis. Subjects were selected purposively. The data collection process involved in-depth interviews. The results of the study show that adolescents' perceptions of ghosts are complex and influenced by several factors, namely culture, social media, religion, social narratives, and individual experiences. These results indicate that understanding the dynamics of the formation of adolescents' perceptions of metaphysical phenomena in the digital era is very important. This has an impact on developmental and educational psychology, especially in helping adolescents understand and manage their emotions, imagination, and the way they think about supernatural stories.

Mental health remains a critical priority, as individuals with good mental well-being tend to experience a higher quality of life. However, mental health issues such as depression, anxiety, and psychological distress are increasingly prevalent among university students. One contributing factor to these issues is the excessive use of social media, driven by rapid technological advancements. This study aims to empirically examine the relationship between social media addiction and mental health among university students. A quantitative approach was employed, with the population consisting of students from University X. The sampling technique used was purposive sampling, involving a total of 111 students. Data were analyzed using Pearson’s product-moment correlation to test the research hypothesis. The results indicated a significant negative relationship between social media addiction and students’ mental health (r = -0.407; p < 0.01). These findings suggest that the higher the level of social media addiction, the lower the level of mental health among students, and vice versa.

This study aims to examine the relationship between religiosity and self-esteem with premarital sex behavior among Gen-Z in Yogyakarta. The study involved 100 respondents with the characteristics of being university students aged 17-24 years, residing in Yogyakarta, and having a tendency toward casual sex behavior. The sampling technique used was Accidental Sampling. The data analysis technique applied in this study was multiple linear regression. The results showed that casual sex behavior is significantly influenced by religiosity and self-esteem (p=0.029<0.05). However, religiosity alone does not have a significant relationship with casual sex behavior (p=0.078>0.05), while self-esteem has a significant relationship with casual sex behavior (p=0.012<0.05). Based on these findings, it is crucial to internalize religious values among Gen-Z. Additionally, building healthy self-esteem should be positively directed through character education that emphasizes self-achievement, thereby reducing the tendency toward casual sex behavior among Gen-Z.
