Sukoharjo Regency, Central Java, is an example of successfully implementing rice planting using the Planting Index 400 (IP-400). This study aimed to analyze the difference in total farming costs between IP-400 and non-IP-400 rice varieties and their sustainability. Farmers in Sukoharjo have succeeded in planting rice three to four times a year in rice fields with technical irrigation. This activity was carried out in five stages, i.e. 1) a Discussion with the Head of the Sukoharjo Regency Agriculture and Fisheries Service, Central Java and his staf; 2) Focus Group Discussion (FGD) with the Head of the Sukoharjo Regency Agriculture and Fisheries Service, Heads of Farmer Groups and their members, Delegates from the Directorate General of Food Crops, Ministry of Agriculture, as well as related parties; 3) Field visits to rice seed entrepreneurs; 4) Field visits to "integrated farming" entrepreneurs who implement IP-400 rice cultivation; and 5) Field visits and interviews with farmers accompanied by extension workers and the Department of Agriculture as farmer advisors. Socialization and discussions have effectively increased stakeholders’ understanding of the implementation of IP-400 rice planting. This success is due to adequate technical support and infrastructure and close cooperation between farmers, local governments, and other related parties.

Probabilistic tsunami hazard analysis of Batukaras, a tourism village in Indonesia

Abstract. Indonesia's location in the middle of tectonic plates makes it vulnerable to earthquakes and tsunamis, especially in the megathrust zone around the island of Sumatra and the southern part of the island of Java. Research shows a seismic gap in southern Java, which poses a potential threat of megathrust earthquakes and tsunamis, impacting coastal areas such as Batukaras in West Java, a popular tourist destination. To prepare for disasters, probabilistic tsunami hazard analysis (PTHA), which focuses on seismic factors, was carried out by modelling tsunamis on 3348 sub-segments of 4 large megathrust segments in the south of Java. Stochastic earthquake modelling was used to simulate the occurrence of a tsunami from an earthquake with Mw 6.5 to the highest potential magnitude. This research shows that the PTHA in Batukaras reveals varying heights of 0.84, 1.63, 2.97, and 5.7 m for each earthquake return period of 250, 500, 1000, and 2500 years, respectively. The dominant threat arises from the West Java–Central Java megathrust segment, emphasising the importance of preparedness, although the annual probability of tsunamis is generally low. Our study will deepen knowledge of tsunami hazards associated with megathrust activities near Batukaras for mitigation planning and decision-making, and it can become a reference for similar coastal tourist areas.

Augmented Reality-based Rebuttal Texts (ARaRaT) on Momentum-Impulse: Rasch Analysis on Students’ Conceptual Change

This study aimed to implement Augmented Reality-based Rebuttal Texts (ARaRaT) on momentum-impulse in the Predict Discuss Explain Observe Discuss Explain (PDEODE) strategy to identify students’ conceptual change. The design used in this study was an embedded mixed method. The research instrument used was 10 diagnostic test questions in a multi-tier format on momentum and impulse. The respondents in the study were 31 students (9 males and 22 females) of grade XI at one of the state high schools in Central Java, Indonesia. Data analysis was carried out with three categories of conceptual change, namely Acceptable Change (AC), Unacceptable Change (UC), and No Change (NC). Rasch analysis was used to map the comparison between the quality of respondents to the instruments used. The results showed that there was a change in conception in the AC category (32%), NC (44%), and UC (25%). Meanwhile, the highest change in misconceptions occurred in the AC category in question T5 (26%) and the lowest in questions T4 and T10 (10%). These results are supported by Rasch analysis which shows that in general there is a change from pretest to posttest. However, the probability of a change in conception can also be seen from the results of the analysis of Andrich Thresholds. Likewise, for the confidence level, students become more confident than before in answering questions. But this probability only shows the possibility that can occur when there is a category change. Furthermore, these results can be recommendations for other researchers in developing and implementing AR in physics learning.

Spatial Probit Regression Analysis Using Recursive Importance Sampling on the Human Development Index in Central Jawa Province

This research aims to analyze the Human Development Index (HDI) in Central Java Province using two modeling approaches: the probit model and the spatial probit model. HDI, a crucial indicator of quality of life, is categorized into two groups: medium-low and high. Among the 35 districts and cities in Central Java, 9 fall into the medium-low category (35%), while 26 are classified as high (65%). Brebes Regency has the lowest HDI at 69.54, whereas Sukoharjo City boasts the highest HDI at 77.73. The results reveal that the spatial probit model provides a superior classification of HDI compared to the probit model. The mapping of prediction results highlights the discrepancies between actual and predicted HDI categories. This study underscores the advantage of incorporating a spatial approach, enhancing the accuracy of HDI analysis, and offering a more nuanced understanding of spatial distribution and dependencies in human development within Central Java. Further research is recommended to include additional variables, such as poverty levels or access to education, which spatial factors may also affect. Moreover, this method can be applied to other regions or enhanced using more complex spatial models, such as spatial autoregressive (SAR) or geographically weighted regression (GWR), for deeper and more comprehensive analysis.
