A Nonparametric Regression Approach Address Poverty Problems in East Nusa Tenggara Province
Full text linkThe administration is focused on reducing poverty, which is still a significant issue. Since the regression curve is unknown and the truncated spline nonparametric regression approach offers a high degree of flexibility, the study was conducted to determine what factors influence it, particularly in the East Nusa Tenggara area. The goal of this study is to develop a nonparametric regression model. The average length of schooling, life expectancy, percentage of the illiterate population aged 15 and over, labor force participation rate, percentage of households based on the information source, and population density affect poverty in the East Nusa Tenggara area. With a minimum GCV of 39.57, it was determined that 1 knot point were the ideal knot point. To some extent, the characteristics that influenced poverty were life expectancy, labor force participation rate, percentage of households with a proper light source, and population density. The best model met these criteria with an R2 of 81.28%. The findings suggest that targeted interventions to improve these factors can significantly reduce poverty in East Nusa Tenggara

Behaviour Study of Abutment Foundation Pile on Lightweight Embankment Oprit (Case Study: Kali Otek Bridge – Lamongan North Ring Road Construction Package Section 2)
Full text linkThe Kali Otek Bridge is in the Lamongan North Ring Road Development Package Section 2 with a bridge span length of 40.8m. The boring test results show that the subgrade is included in the very soft soil classification to a depth of >15 meters. The existing condition is a pond area that can be inundated with water reaching a height of 1 meter, thus affecting the occurrence of land subsidence and stability of the bridge abutment foundation pillars. The existence of embankment construction can also cause subsidence on the subgrade.In this research, soil settlement and stability analysis of lightweight foam mortar embankment has been carried out by varying the percentage of the height of the existing embankment and the foam mortar. In addition, it also analyzes the effect of using lightweight embankment, both as a whole and its variations on the stability of bridge abutment foundation piles, both with and without Prefabricated Vertical Drain (PVD).The analysis showed that the use of foam mortar reduced the subgrade settlement by 61.2% with a longer time of 18.5%. The smallest settlement and lateral deflection was at 100% foam mortar backfill variation with consolidation time of 190 days. The greater the percentage of foam mortar height, the smaller the settlement as the factor of safety increases. Thus, the use of foam mortar can be an alternative embankment for bridge oprites on soft soil
JOURNEY OF VERNACULAR ROOF TYPOLOGY IN SLAGI VILLAGE
Full text linkVernacular architecture is identified as a form of architecture that evolves with the times. The concept of this architecture remains relevant because rural communities tend to build their homes based on longstanding traditions passed down through generations. However, changes in vernacular architecture can occur due to various factors, including adaptation to modern developments and residents' needs. In this article, the evolution of vernacular roof forms from the past to the present is analyzed, focusing on the vernacular roofs of houses in Slagi Village. Through a comparative study of old and new vernacular house roofs, the evolution of vernacular roof architecture is explored, and the factors influencing roof shape changes are investigated. Descriptive and comparative analysis approaches are used to review the differences in roof forms, and the cultural and environmental implications of these changes are understood. Findings show significant changes in vernacular roof forms from the past to the present, influenced by technological advancements and architectural trends. This article provides deep insights into the transformation of vernacular architecture and highlights the importance of preserving cultural heritage in the context of changing times. With a better understanding of the evolution of vernacular architecture, it is hoped to raise awareness of the importance of safeguarding and preserving cultural heritage for future generations
Representasi Nilai Pendidikan Lingkungan Novel Jejak Balak Karya Ayu Werilang (2023): Kajian Ekokritik
No full textThis study is a qualitative research with a descriptive approach that aims to examine the value of environmental education in the novel Jejak Balak by Ayu Werilang (2023). The primary data source is the novel’s text, focusing on environmental phenomena, while secondary sources include journals, books, and previous studies relevant to ecocriticism and environmental education. Data collection techniques involve documentation and note-taking from the novel and other written sources. The data were analyzed using Greg Garrard’s (2004) ecocritical approach, which consists of six main concepts: pollution, wilderness, apocalypse, dwelling, animals, and earth. The research findings indicate that Jejak Balak represents environmental education values through these six aspects in line with Garrard’s theory. The novel highlights issues such as forest conservation, criticism of environmental exploitation and irresponsible corporations, the role of local wisdom in environmental sustainability, the ecological impact of deforestation, animal symbolism in human-nature relationships, and the role of characters as environmental change agents. As an ecologically themed literary work, the novel serves as an educational and reflective medium, emphasizing human responsibility in maintaining ecological balance and raising awareness of environmental issue
Application of the finite element method for evaluating the stress due to operating load in high energy piping system
Full text linkThe stress value of the piping system will change during operating conditions. The stress value affects the integrity of the piping system. Excessive stress will cause deformation and damage to the piping system. The operating condition parameters of the piping system are temperature and pressure. The High-Energy Piping (HEP) system is subjected to high pressures and temperatures, which can cause significant stresses on the piping components. So stress analysis needs to be carried out to ensure that the piping system has strength and flexibility. The Cold Reheat Pipe (CRP) steam line is one of the High-Energy Piping Systems in this steam power plant. CRP consists of CRP BS 130 and CRP BS 131. This paper is about evaluating the stress due to operating loads in 2024 (temperature, pressure, and remaining thickness) for steam lines on the high-energy piping system using the finite element method and refers to ASME B31.1. The output stress values in the piping system in this paper consist of stress due to sustained load, stress due to thermal load, and hoop stress. The CRP BS 130 modeling results show the maximum stress due to sustained load (166.6 kg/cm2), the maximum stress due to the thermal load (112.8 kg/cm2), and the maximum hoop stress (855.6 kg/cm2). The CRP BS 131 modeling results show the maximum stress due to sustained load (974.2 kg/cm2), the maximum stress due to the thermal load (123.5 kg/cm2), and the maximum hoop stress (938.9 kg/cm2). The results of the stress evaluation due to the operating load were still below the allowable stress and are still permitted by the ASME B31.1 Code.
The Role of High-Income Households and Tourism in Advancing Energy Affordability and Financial Inclusion for Small Islands
Full text linkEnergy affordability and financial inclusion remain critical challenges for small island communities, where reliance on imported fossil fuels and high energy costs disproportionately impact low-income households. At the same time, high-income households and the growing tourism sector on these islands hold significant financial capacity to drive equitable energy transitions. This perspective explores the role of high-income stakeholders and tourism operators in promoting energy affordability through retribution mechanisms, adaptive service assets, and flexible organizational models. By leveraging financial resources and investing in clean energy solutions, high-income households and tourism businesses can contribute to a sustainable energy future that benefits all members of the community, bridging the gap between economic growth, energy equity, and environmental sustainability
Stress Analysis on Emergency Pipeline from Flare to Pressure Vessel
Full text linkThis work focuses on the analysis of emergency piping systems connected to flares and pressure vessels at oil and gas facilities in West Papua. The main objective is to determine support placement, and analyze pipe stress on flares and pressure vessels. The methods used include calculating the maximum allowable pipe span, stress analysis based on ASME B31.3. The results of the research show that a 6 in emergency pipe line requires a minimum of 2 supports with a maximum allowable pipe span of 36.967 ft. The pipe flexibility value of 0.00146 is still below the limit of 0.02582 set by ASME B31.3. Stress analysis due to sustained, occasional, and thermal expansion loading shows the highest values respectively of 2572.5 lb/in² (12.6% of the permit limit), 1294.0 lb/in² (18.9% of the permit limit for seismic loads), 595.0 lb/in² (2.2% of the permit limit for wind loads), and 23921.3 lb/in² (49.3% of the permit limit)
