Abstract

Food insecurity is a condition in an area, community or household where the level of security and availability does not meet the standards needed for the growth and health of the majority of the population. Kangkung is a heavy metal-absorbing weed plant that many people like as a vegetable. Food security in urban communities is limited by existing land and growing media, so using media from sewer sediment is an alternative. The experiment used a factorial Randomized Block Design (RAK), consisting of two factors, namely the dose of chicken manure (A) with 4 levels as follows: a0 : 0 t ha-1 (control), a1 : 10 t ha-1, a2 : 20 t ha-1 and a3 : 30 t ha-1 and Kangkung Variety (K) with 4 levels as follows: k0 : Serimpi Variety, k1 : Amanda Variety, k2 : Bangkok LP-1 Variety and k3 : Bika Variety, so there are 16 treatment combinations repeated 2 times. The research findings indicated that there was no significant correlation between the dosage of chicken manure and the plant type in terms of plant growth, yield, and absorption of PB heavy metals, with the exception of leaf count. The optimum dose of chicken manure is 5.05 t ha-1 in the Serimpi variety with a maximum number of leaves of 11.30 plants-1, 5.27 t ha-1 in the Amanda variety produces a maximum number of leaves of 16.68 plants-1 , 9.20 t ha-1 in the Bangkok LP-1 variety produces a maximum number of leaves of 16.77 plants-1 and 3.83 t ha-1 in the Bika variety produces a maximum number of leaves of 18.66 plants-1.

Abstract

Indonesia has undergone a transformation from agriculture to the manufacturing industry in 1971-1997. In the 2001-2015 period there was de-industrialization in developed countries. Likewise, Indonesia which shows a decrease in the contribution of GDP and manufacturing sector workforce to the economy. However, deindustrialization in Indonesia is premature / too fast. One of the policies to overcome this problem is with attention to the creative industry. With the existence of the creative industry, it can achieve several SDGs goals, namely the 8th goal, namely decent work and economic growth, the creative economy can increase economic growth, create jobs and increase exports (UNCTAD, 2010). However, the creative industry GDP growth that is below the RPJMN target is thought to indicate low productivity of the creative industry. According to IBS data, the craft sub-sector creative industry has a low production value. To see productivity can use technical efficiency. This study aims to evaluate the technical efficiency of creative industry in the craft sub-sector as well as to analyze the trend of variables that affect technical judgments. The method used is the CES production function and Data Envelopment Analysis. The results show that industries that have high total production factor values have a tendency to have high technical efficiency values as well. Furthermore, those arranged according to technical categories and binary logistic regression are used to determine trend variables that affect technical judgments. The technical efficiency of the craft, significantly by wages, investment status and company scale.

Abstract

The crisis in food security is a problem in many countries including Indonesia. The crisis is important to pay attention to, in order to realize sustainable food security in accordance with the second Sustainable Development Goals (SDGs) of zero hunger. Achieving food security cannot be separated from making appropriate and targeted policies. Policy making must be supported by accurate, comprehensive and systematic food security information. This study aimed to classify districts/cities in Indonesia into food-secure and food-prone areas and analyze the factors that influence the food security status. The data were analyzed descriptively and inferentially where clustering with k-means method for food security status classification and Geographically Weighted Logistic Regression (GWLR) modeling with Adaptive Gaussian kernel function weights which provided the best model with the smallest Akaike Information Criterion corrected (AICc) compared to other kernels to see the spatial influence in determining the food security condition of a district/city. The results showed that in 2022 there were 388 districts/cities with food security status and 126 districts/cities with food insecurity status. In addition, of the 9 variables used in clustering, there are 5 variables used in GWLR modeling. Three of them are significant in all regions in Indonesia, while 1 variable is locally significant in some regions.

Abstract

Economic growth and labor productivity are important things for a region. This research analyzes the influence of investment, technological change, health, and minimum wages on economic growth and labor productivity. The geographically weighted regression (GWR) model is used to analyze spatial data, which produces local parameter estimates for each point/location where the data is collected. It was found that investment significantly affects economic growth in 18 provinces in Indonesia. ICT has a significant effect on economic growth in 3 provinces, and education (PPT) has a significant impact on labor productivity in 23 provinces. Low quality of health significantly affects the economic decline in 2 provinces and the decline in labor productivity in 4 provinces. The provincial minimum wage variable (UMP) significantly increases labor productivity in 17 provinces. Overall, of the 34 provinces, economic growth was most influenced by significant investment in almost all provinces except for Sumatra Island and half of Java Island. Meanwhile, labor productivity is most influenced by education, which is significant in almost all provinces except in eastern Indonesia and half of Sumatra Island.

Abstract

The rapid growth of digital technology has driven significant transformations in the labor market, marked by the emergence of the gig economy. While offering flexibility, gig workers is often accompanied by legal uncertainties and a lack of social protection, raising concerns about worker welfare. This study aims to identify the factors influencing gig workers' wages in Indonesia from economic, social, and digital perspectives. The analysis uses panel data from 34 provinces over the 2018–2023 period, sourced from BPS. The analytical method employed is the fixed effect model, corrected using the seemingly unrelated regression approach to address issues of heteroskedasticity and inter-regional correlation. The results show that inflation, human development index, open unemployment rate, ICT readiness, and ICT intensity significantly affect gig workers’ wages. ICT readiness has a positive impact, whereas the ICT intensity has a negative effect on wages. Meanwhile, ICT skills do not show a significant influence. This study highlights the need for inclusive digital policies and strengthened worker bargaining power to build a sustainable gig economy ecosystem.

Abstract

Background: Reading comprehension represents a crucial aspect of learning English effectively, yet many junior high school students struggle to interpret and engage meaningfully with texts. Purpose: This study examines the impact of the Question Answer Relationships (QAR) strategy on enhancing students’ performance in reading comprehension. Method: This study employed a quantitative one-group pretest–posttest design involving 30 students from an Islamic Public Junior High School (JHS) in Karanganyar, selected through simple random sampling. Pre- and post-tests based on descriptive texts aligned with the national English curriculum were administered, and the data were analyzed using descriptive statistics and a paired-sample t-test to assess changes in students’ reading comprehension. Results and Discussion: The analysis showed that employing the QAR strategy resulted in a notable enhancement of students’ reading comprehension abilities. The average score improved from 22.67 on the pre-test to 32.53 on the post-test. Statistical results from the paired-sample t-test verified a significant improvement (t = –26.191, p < .001), indicating the effectiveness of the intervention. These results suggest that QAR supports students’ understanding of text by helping them differentiate between information derived directly from the text and knowledge constructed from prior understanding, thereby strengthening metacognitive engagement and filling the gap in strategies for fostering comprehension at the junior high level. Conclusions and Implications: The implementation of the QAR strategy provides a learning experience that guides students to think critically, understand the relationship between questions and the text, and gradually enhance their reading comprehension skills. QAR can serve as an innovative instructional approach for English teachers to foster students’ deeper understanding of reading comprehension.
