Abstract

Poverty factors are multidimensional and complex. Currently, to predict the number of people living below the poverty line using the concept of linear thinking. It is necessary to study the causal relationships among poverty factors in form of a system dynamics model. This study aims to predict the poverty rate people in “The Golden Indonesia” 2030 using poverty macro models. The data used are time series data from 2009 to 2018 at the national level (Indonesia), and data sources from the BPS Statistics-Indonesia, and the Ministry of Environment and Forestry of the Republic of Indonesia. The research method uses a system dynamics model, where the system of thinking is created based on the two-stage least square (2SLS) simultaneous equation model. The 2SLS simultaneous equation model testing results show that there are three significant simultaneous equations, including poverty, economic growth, and human development index. Furthermore, the three simultaneous equations show a causal loop diagram (CLD) in a system dynamics model. The mean absolute percentage error (MAPE) is 2.34%, meaning that the macro poverty model is valid. The scenario formats for prediction include “optimistic” for economic growth and the “moderate” for human development index (HDI), total population, unemployment, and environmental quality index variables. The predicted percentage number of poor people in 2030 is 4.12%, a positive deviation of 0.12% from the government’s target of 4%. All parties need to work hard and together for the “optimistic” scenario to be implemented, which is to raise Indonesia’s economic growth to 7.4%. This study assumes that there is no Covid-19 problem and only predicts 10 years due to limited data used in 2010-2018. The novelty of this study is the alignment of the prediction results between the system dynamics and the simultaneous equation models. In general, the system dynamics model is valid and could answer the complexity of a phenomenon to predict poverty.

Abstract

Education is essential for improving the quality of Indonesian society. Indonesia participated in the Programme International Students Assessment (PISA) survey to improve the quality of education. Based on the 2018 PISA survey data, Indonesia's reading literacy score has a hierarchical data structure, which means students at level 1 are nested by schools at level 2. The multilevel model is an appropriate approach to analyze such hierarchical structures. However, quantitative analysis of PISA data is still rarely carried out. This study aims to analyze the explanatory variables that significantly affect Indonesian students' reading literacy from the PISA survey using multilevel regression. This study examined student-level and school-level explanatory variables obtained from the Organization for Economic Cooperation and Development (OECD). Significant parameter tests revealed that, at the student level, factors such as socioeconomic status, teacher support in language learning, teacher-directed instruction, enjoyment of reading, perceived difficulty, competitiveness, mastery goal orientation, disciplined classroom climate in reading, general fear of failure, attitudes toward school, and perceived feedback significantly influence reading literacy. At the school level, school size was found to be a significant factor affecting reading literacy scores. Furthermore, the Intraclass Correlation Coefficient (ICC) indicated that schools accounted for 49% of the total variance.

Abstract

Jakarta, as one of the metropolitan cities in Indonesia, has various problems in the waste sector. According to the 2022 National Waste Management Information System (SIPSN), daily waste generation in DKI Jakarta in 2022 is 8,527.07 tons with a reduction of around 26% in each administrative city area. This research uses literature studies based on several theories and research regarding waste problems with the aim of increasing community participation in implementing Minister of the Environment Regulation Number 13 of 2012 concerning Guidelines for Implementing Reduce, Reuse, Recycle through Waste Banks as an effort towards a circular economy. The results of the analysis using the Analytic Hierarchy Process (AHP) method with the help of the Superdecision Application show the weight of the criteria for determining waste processing in order from highest, namely showing that social aspects have the highest preference (51.49%), environmental aspects (28.24%), economic aspects (11.89%) and technological aspects (8.37%). Meanwhile, the alternative priority order with the highest preference is Compost at 51.617%, followed by the Recycle method at 24.40%, Incineration at 15.61% and the Landfill method at 8.36%. with an Inconsistency value of 0.02. This shows that the calculation of these criteria still falls within the inconsistency threshold, which cannot be more than 0.1.

Abstract

Background: Kualitas pendidikan yang unggul menuntut guru untuk memiliki kompetensi literasi digital, kemampuan berpikir kritis, dan keterampilan kolaboratif. Namun, kesenjangan kompetensi digital guru di Indonesia masih cukup besar, khususnya dalam kemampuan mendesain media pembelajaran visual seperti infografis. Penelitian ini bertujuan untuk menganalisis pengaruh pelatihan pembuatan infografis terhadap peningkatan kompetensi guru dalam mendesain media pembelajaran digital interaktif. Metode penelitian menggunakan desain eksperimen semu (quasi-experimental) dengan model one-group pre-test and post-test. Sampel penelitian berjumlah 15 guru SMP di Kabupaten Sukabumi yang dipilih secara purposif. Data dikumpulkan melalui kuesioner pre-test dan post-test untuk mengukur pengetahuan konseptual dan persepsi guru terhadap infografis. Analisis data dilakukan dengan uji Wilcoxon Signed-Rank dan perhitungan effect size. Hasil penelitian menunjukkan adanya peningkatan signifikan pada kompetensi guru setelah pelatihan (p = 0,000714 < 0,05) dengan nilai effect size sebesar 0,881 yang termasuk kategori pengaruh sangat besar. Hal ini menunjukkan bahwa pelatihan pembuatan infografis efektif dalam meningkatkan keterampilan guru baik secara teknis maupun pedagogis. Dengan demikian, pelatihan ini berkontribusi dalam memperkuat literasi digital dan kemampuan komunikasi visual guru di era pembelajaran digital.

Abstract

Integrasi sistem transportasi yang efektif dan efisien berperan penting untuk kemajuan antar sektor ekonomi dan antar wilayah, kedaulatan serta ketahanan ekonomi nasional. Kebijakan Sistem Transportasi Nasional (SISTRANAS) dan Cetak Biru Pengembangan Sistem Logistik Nasional (SISLOGNAS) telah meningkatkan aksesibilitas, perdagangan, produktivitas, investasi, dan lapangan pekerjaan. Namun, fenomena berupa ketimpangan infrastruktur, disparitasi harga, tingginya biaya transportasi dan logistik di atas rata – rata dunia, kecelakaan transportasi, tingkat kemacetan, dan polusi masih menjadi tantangan yang harus diselesaikan. Integrasi SISTRANAS dan SISLOGNAS memiliki peran penting dalam meningkatkan efektivitas kebijakan publik sistem transportasi terintegrasi. Penelitian ini bertujuan untuk membuktikan pengaruh secara empiris integrasi kedua sistem tersebut terhadap efektivitas kebijakan publik sistem transportasi terintegrasi di Indonesia. Metode Structural Equation Modelling dengan menggunakan perangkat lunak Jamovi digunakan untuk memahami hubungan antara variabel yang mempengaruhi perwujudan kebijakan implementatif. Hasil penelitian menunjukkan bahwa integrasi SISTRANAS dan SISLOGNAS secara empiris berpengaruh signifikan terhadap kebijakan publik sistem transportasi terintegrasi. Indikator konektivitas multimoda, pelayanan, interkonektivitas, dan dampak kebijakan memiliki pengaruh terbesar pada setiap variabel penelitian. Rekomendasi yang dapat dipertimbangkan adalah penguatan integrasi sistem yang dimiliki antar pemangku kepentingan, penyusunan kebijakan sistem transportasi terintegrasi, peningkatan kualitas layanan serta investasi infrastruktur transportasi dan logistik, dan pengembangan model kebijakan.
