Productivity Optimization of Rainfed Rice Land in Nagari Pungasan Utara, Regency of Pesisir Selatan through Determinant Factor Analysis
No full textThis study aims to determine the productivity of land in rainfed lowland rice farming and analyze the factors that influence the productivity of the land in North Punggasan Nagari, Linggo Sari Baganti District, Pesisir Selatan Regency. This research was conducted in Nagari Punggasan Utara in June-July 2022. The method used is a survey method. The total population is 489 rainfed rice farmers with a total sample of 83 farmers. The data analysis method used is descriptive quantitative with multiple linear regression analysis. The results showed that the productivity of rainfed lowland rice was 3.09 tons/ha on average. Factors that affect land productivity (simultaneously) are land area, labour percentage in family (TKDK), labour percentage outside family (TKLK), use of NPK fertilizer, SP26 fertilizer, Urea fertilizer, pesticides, seeds, age, education, and experience. Partially the ones that have a significant effect are labour percentage outside family (TKLK), seeds, and pesticides. Meanwhile, land area, labour percentage in family (TKDK), NPK fertilizer, SP36 fertilizer, Urea fertilizer, age, education, and experience have no significant effect on the productivity of rainfed lowland rice. The coefficient of determination (R2) is 0.633. The need for machine and equipment assistance as well as the expansion of information on cultivation techniques to farmers in the form of training, counseling, and farming demonstrations so that farmers will be able to be more productive in carrying out their farming activities, so that land productivity increases and reduces the use of labor in the family
NUMERICAL ANALYSIS OF ELECTRIC FORCE DISTRIBUTION ON TUMOR MASS IN DC ELECTRIC FIELD EXPOSURE
No full textResearchers have used electric fields as a new therapeutic strategy to treat cancer for the past 15 years. Tumor Treating Fields (TTFields) is an alternating electric field-based cancer therapy approved by the US FDA to treat glioblastoma multiforme (GBM). ECCT (Electro-Capacitive Cancer therapy), a DC charged-discharged electric field (EF) cancer therapy, also shows a performance inhibiting cell proliferation. ECCT affects the cancer lesions to cause simultaneous death of the cancer cell and detached off of the surrounding tissue. The author hypothesizes that the EF produces an electric force that is not homogeneous throughout the tumor mass and generates a strong dielectrophoresis force. The force affects microtubules polymerization during mitosis and causes mitotic arrest. To examine this hypothesis, we performed a numerical simulation of the EF distribution and calculated the force acting on the tumor mass generated by the EF. We analyzed DC electric field exposure on a cancer lesion using a single lesion 2D circular model, calculated the EF intensity on the lesion using the Finite Element Method, and the dielectrophoresis force distribution to quantify the treatment efficacy. The results showed that the distribution of EF intensity was not homogeneous at the lesion-medium boundary and homogeneous within the lesion. The EF intensity is highly dependent on the dielectric constant of the medium and the applied voltage difference that may affect the effectiveness of the treatment. Variations in lesion diameter had no significant effect on the EF intensity distribution and, hence the effectiveness of the therapy. It is considered that EF exposure by ECCT generated strong force on the lesion-medium boundary that could cause detachment of the tumor mass from the surrounding tissue
Income Paradox and Socioeconomic Determinants of Household Dietary Diversity in Rural Developing Contexts
No full textDietary diversity is a crucial indicator of nutritional adequacy and food security, especially in rural developing areas where access to varied foods remains limited. This study aimed to measure household dietary diversity and identify the socioeconomic and behavioral determinants that influence the Food Consumption Pattern Score (Pola Pangan Harapan/PPH) in Nagari Tandikek Utara, Padang Pariaman Regency, Indonesia. A cross-sectional quantitative design was employed, involving 150 households selected through proportional random sampling, with data collected using structured questionnaires, interviews, and field observations. Dietary diversity was assessed across nine food groups using the PPH method, while multiple linear regression analysis (SPSS 23) examined the effects of income, family size, eating habits, mother’s education, head of household’s education, and mother’s age. Results showed that the average PPH score was 51.69%, indicating low dietary diversity, with consumption predominantly centered on cereals (18.26%) and insufficient intake of legumes, animal-source foods, vegetables, and fruits. Regression findings confirmed an income paradox, as income had a significant negative effect (B = −9.398; p = 0.000), while family size (B = −2.294; p = 0.000) and mother’s education (B = −1.077; p = 0.000) also reduced dietary diversity; conversely, the household head’s education improved it (B = 1.070; p = 0.000). These findings indicate that dietary diversity is shaped by intersecting socioeconomic and demographic factors, highlighting the need for integrated strategies—combining nutrition education, gender-responsive approaches, and improved food access—to support progress toward achieving Zero Hunger (SDG 2) in rural communities.
