Strategi Pengurangan Ketimpangan Pendapatan di Jawa Barat Melalui Peningkatan Pendidikan dan Pengurangan Kemiskinan

Income inequality remains a major challenge in the economic development of West Java Province, despite positive economic growth in recent years. This study aims to analyze the effects of economic growth, education level, and poverty rate on income inequality across 27 regencies/cities in West Java during the 2019–2023 period. The method employed is panel data regression using 135 observations, analyzed through the Fixed Effect Model (FEM) based on the results of Chow and Hausman tests. The findings reveal that economic growth does not have a significant effect on income inequality. In contrast, education level and poverty rate are found to significantly influence income inequality. These results underscore the importance of enhancing education quality and reducing poverty as strategic efforts to mitigate income disparities. The study also indicates that non-inclusive economic growth alone is insufficient to reduce income inequality. Policy implications point to the need for improving access to education and implementing empowerment programs for the poor. This study is limited by the scope of variables and the relatively short time frame, suggesting the need for future research using a more comprehensive and extended approach

Facile Synthesis of Vaterite Fine Powder CaCO3 from Padalarang Natural Limestone with pH Modifying via Fine-Bubble Carbonation

Abstract Natural limestone, known for its high calcium carbonate (CaCO₃) content (~ 95%) and safety in health applications, is widely used in science and industry. It exists in three forms: calcite, vaterite, and aragonite. Vaterite's spherical structure, non-toxic nature, biocompatibility, and high porosity is particularly valuable for biomedical applications. However, its metastability makes it more challenging to synthesize consistently compared to calcite and aragonite. This study aimed to synthesize CaCO3 from natural limestone from Padalarang, West Java, Indonesia, using a fine-bubble carbonation method, varying HCl concentrations to assess pH’s influence on vaterite formation. The method involved converting natural limestone to CaO then to Ca(OH)2 as the primary carbonation precursor. Fine CO2 bubbles were introduced into a Ca(OH)2 solution (a mixture of 5% water and 95% methanol), with HCl concentrations of 0.02 M, 0.04 M, and 0.08 M added. The carbonation process was conducted at 300 rpm, 20±3°C, and a flow rate of 1L/min for 2 hours. The CaCO₃ powders were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electronic microscopy (SEM), and a particle size analyzer (PSA). The XRD result indicated that a 0.04 M HCl concentration yielded the highest vaterite content (93%). SEM shows the spherical morphology of vaterite CaCO3 both in 00.4 M and 0.08 M HCl concentrations, while FTIR confirmed the presence of calcite (712, 872, 1087 cm-1) and vaterite (744 cm-1). PSA showed that HCl concentration influenced particle size and the calcite-vaterite ratio, with Z-average particle sizes ranging from 114.8 nm to 118.2 nm.

Measuring poverty of province of Java using micro data, are the results the same as macro data?

Poverty is a problem that still occurs in many countries, both developed and developing countries. One of the important pieces of information from using microdata is to provide a map of the characteristics of the target households. Characteristics of poor households obtained through analysis of micro poverty data. The data used in this study is IFLS (Indonesian Family Life Survey) 5 data using data from the Provinces of DI Yogyakarta, West Java, Central Java, East Java, DKI Jakarta, and Banten. The variables used are characteristic variables from the Multidimensional Poverty Index (MPI) indicators, namely household health, health insurance, school level, and quality of household life in the form of sanitation, drinking water, electricity, cooking fuel, vehicles, electronics, and savings. This study found that there are differences in poverty calculated by applying monetary and multidimensional poverty. This research shows that monetary (consumption) alone is not enough to explain the deprivation faced by the poor. The low level of education, health, and household quality in the form of drinking water is a concern for the government to evaluate existing programs and policies.

Peristiwa Alih Kode dan Campur Kode Bahasa pada Masyarakat Pesisir Pelabuhan Ratu, Sukabumi

This study aims to analyze code switching and code mixing events in the coastal community of Pelabuhan Ratu, Sukabumi, West Java. Using a descriptive-qualitative research method, data were collected through observation and semi-structured interviews with research subjects, namely fishermen and traders around Pelabuhan Ratu. The data samples were 4 fishermen at the Fish Auction Market and 2 traders at the Traditional Market. The results showed that there were 21 internal code switching events with 18 events in fishermen and 3 events in traders. The significant difference in frequency between the code switching data of fishermen and traders was caused by differences in the background of the research subjects. This affected the speech of indigenous fishermen so that many code switching events occurred, while traders were indigenous people who had lived in Pelabuhan Ratu for a long time. Meanwhile, 37 code mixing events were found consisting of 4 code mixing in the form of words, 22 code mixing in the form of phrases, and 11 code mixing in the form of clauses. Based on these data, code switching events generally occur when speakers adjust their language to their conversation partners, while code mixing occurs because of the speaker's habit of mixing the use of Indonesian and Sundanese in everyday conversation. This study implies that the coastal community of Pelabuhan Ratu is a bilingual community that actively uses Indonesian and Sundanese in everyday communication. This finding can contribute to the development of sociolinguistic studies in other coastal areas. In addition, it can also be a suggestion and input for educational institutions to develop policies on the use of Indonesian in public spaces and the maintenance of local languages in the Pelabuhan Ratu area. Keywords: code switching, code mixing, bilingual speakers, coastal community linguistics, language maintenance
