Abstract

Penelitian ini bertujuan untuk menganalisis hubungan antara media pembelajaran konvensional dan digital terhadap learning gain dan partisipasi aktif siswa pada mata pelajaran Matematika di SD Kusuma Putra Surabaya. Penelitian menggunakan pendekatan kuantitatif dengan jenis komparatif. Sampel terdiri atas 40 siswa kelas 5 yang dibagi menjadi dua kelompok berdasarkan jenis media pembelajaran yang digunakan. Data dikumpulkan melalui tes (pre-test dan post-test) serta observasi partisipasi aktif. Analisis dilakukan menggunakan uji Chi-square untuk mengetahui signifikansi hubungan dan koefisien Cramer’s V untuk menentukan kekuatan hubungan antarvariabel. Hasil penelitian menunjukkan adanya hubungan yang signifikan. antara media pembelajaran dan learning gain siswa (p-value = 0,004; Cramer’s V = 0,27), namun tidak terdapat hubungan signifikan antara media pembelajaran dan partisipasi aktif siswa (p-value = 0,924; Cramer’s V = 0,0039). Dengan demikian, media digital memiliki hubungan yang signifikan dengan peningkatan hasil belajar, namun tidak menunjukkan hubungan yang berarti dengan tingkat partisipasi aktif siswa.

Abstract

This community service activity aims to design and implement an automatic irrigation system based on soil moisture sensors supported by renewable energy from solar panels at the Social Farming Group 3 Baktijaya in Sukmajaya District, Depok City. The implementation methods include problem identification, system design, socialization, training, implementation, and evaluation based on quantitative surveys involving 17 group members. Evaluation results indicate that 70.6% of respondents consider the automatic irrigation system to be very helpful in land management and efficient water use, while 52.9% state that the system provides tangible economic benefits to the surrounding community. The successful implementation of this technology addressed labor limitations and improved farming productivity in an independent and sustainable manner. These findings emphasize the importance of developing modern agricultural systems based on smart technology and renewable energy as adaptive solutions to climate dynamics and changing urban agricultural needs.

Abstract

Human development is a key indicator used to assess the quality of a country's human resources. Although Indonesia's HDI has experienced a significant increase of 75.02 in 2024, inequality is still a pressing issue, especially in terms of gender representation in the workforce. This study aims to identify the influence of poverty, economic, health, employment and education factors on human development in Java Island by considering gender equality as a mediating variable. The data used in the study is limited to 119 districts/cities in Java Island and sourced from BPS publications, the Health Office and the Education Office. The novelty of this study lies in the use of the Finite Mixture Partial Least Square (FIMIX-PLS) approach with mediation effects which is rarely applied in human development research in Indonesia, as well as allowing the identification of latent population heterogeneity and region-based segmentation. The results of this method reveal two distinct district/city segments in Java, with Segment 1 dominated by the variables in this study that have significant direct and indirect effects through the mediation of gender equality on human development, while Segment 2 has characteristics that emphasize the effect of gender equality. Given these differences in characteristics, it is important that contextual and regional segmentation-based development policies are designed by local and central governments. Statistical segmentation approaches such as FIMIX-PLS make a significant contribution to more targeted policy making. By changing the type of intervention according to specific problems, the government can allocate resources more effectively. This supports the achievement of SDG-10 in reducing inequality.

Abstract

Survival analysis is used to study the timing of an event, such as recovery or death, in the context of medical data. One of the diseases that many people suffer from is stroke. Based on the survey results, the number of stroke sufferers in Indonesia reached 8.3% of 1000 people in Indonesia continues to increase every year, especially among the elderly. The research conducted aims to model the estimation of the type III censored Weibull distribution parameters with the Bayesian Linear Exponential Loss Function (LINEX) method. This study uses secondary data on stroke patients in the period January-November 2024 with a sample of 62 patients at the Haji Surabaya Regional General Hospital. Weibull distribution model with Bayesian approach using Linear Exponential Loss Function (LINEX) was applied to estimate the distribution parameters and survival function. The estimation results show that the parameter α is 6.32342 with an average hospitalization time of 5.9151646 days. MSE value is 0.000270555, which indicates that the estimation model is more accurate in predicting data for the length of hospitalization for stroke patients at the Haji Surabaya Regional General Hospital. The probability value of the survival function of stroke patients who have been hospitalized on the 5th day shows a probability of 82.4% so that no further hospitalization is needed, which indicates that the patient's health condition is improving. In addition, the hazard function analysis shows that the longer a patient is hospitalized, the greater the risk of the patient not recovering.
