EVALUASI PERFORMA MESIN UJI FATIGUE ROTARY DENGAN VARIASI TUMPUAN TETAP DAN GULIR PADA SPESIMEN STAINLESS STEEL 304
Full text linkABSTRAK
Fenomena fatigue atau kelelahan material merupakan salah satu penyebab utama kegagalan komponen mesin akibat pembebanan berulang dengan tegangan yang berfluktuasi di bawah batas luluh (yield strength) maupun tegangan tarik maksimum (ultimate tensile strength). Penelitian ini bertujuan untuk menganalisis karakteristik hasil uji fatigue rotary pada spesimen Stainless Steel 304 dengan tumpuan tetap (fixed support) dan tumpuan gulir (roll support). Pengujian dilakukan menggunakan spesimen berbahan Stainless Steel 304 sesuai standar ASTM A276 dengan variasi beban 60 kg, 80 kg, dan 100 kg. Hasil pengujian menunjukkan bahwa peningkatan beban menghasilkan kenaikan tegangan maksimum namun menurunkan jumlah siklus kelelahan material. Pada beban 60 kg, diperoleh tegangan sebesar 3530,4 MPa dengan 2299,1 siklus dalam waktu 99 detik; pada beban 80 kg diperoleh tegangan 4903,3 MPa dengan 1166,9 siklus dalam waktu 54 detik; dan pada beban 100 kg diperoleh tegangan 6080,1 MPa dengan 506,54 siklus dalam waktu 24 detik. Hasil ini menunjukkan bahwa semakin besar beban yang diterapkan, semakin rendah umur kelelahan (fatigue life) material Stainless Steel 304.

Deconstructing the Criminal Justice System in Nepal: Toward a Victim-Centered Justice Paradigm within the Shadows of a Hybrid Legal System
Full text linkNepal’s criminal justice system, despite undergoing legislative reforms, remains entangled in a historical legacy rooted in hierarchical social structures and patriarchal values. This legal system, marked by minimal implementation of justice principles, has yet to realize a truly participatory and victim-centered model of justice. This study aims to evaluate the extent to which legal reforms in Nepal have ensured more equitable and victim-oriented justice, and how legal transformation within the criminal justice system can be actualized. Through a critical examination of Nepal’s legal history, constitutional texts, and legislative reform initiatives, this article assesses the dissonance between progressive legal theories and practical implementation. Employing a normative-juridical approach with an emphasis on critical legal analysis and a comparative-historical perspective, the study reveals that, despite legislative efforts to reduce inequality and discrimination, law enforcement practices continue to reflect structural disparities that neglect the needs of victims and reinforce state dominance in criminal proceedings. Accordingly, current reforms remain insufficient to achieve substantive change and necessitate an ideological transformation toward a legal paradigm that is more responsive and sensitive to victims’ rights
URBAN WASTE MANAGEMENT AS A GOVERNANCE CHALLENGE : POLICY IMPLEMENTATION AND ACTOR NETWORKS IN BATU CITY
No full textUrban waste management remains a persistent governance challenge in rapidly developing cities, particularly those with tourism-driven economies. This study examines municipal solid waste management in Batu City, Indonesia, focusing on how local governance arrangements shape policy performance. The findings show that, despite the existence of local regulations aligned with national waste policy, implementation remains predominantly disposal-oriented and highly dependent on the Tlekung landfill. Upstream strategies, including waste reduction, segregation, and community-based waste banks, are weakly institutionalized, fragmented, and largely dependent on short-term projects rather than embedded governance mechanisms. These limitations are reinforced by constrained municipal budgets, uneven administrative capacity across governance levels, and the absence of stable coordination between government agencies, community groups, and private waste actors. Seasonal waste surges associated with tourism further strain existing service capacity and expose systemic vulnerabilities in local waste governance. This study highlights that the core challenge lies not in regulatory absence but in fragmented governance and limited cross-sectoral integration. Strengthening collaborative governance arrangements and institutionalizing community participation are essential to shift urban waste management in Batu City from disposal-centered practices toward more sustainable and resilient governance outcomes
Defarmation Against Government in National Criminal Code: Review on Freedom of Expression and Opinion Rights
No full textThe offense of insulting the government or state institutions is considered contrary to the right to freedom of expression and opinion. This study aims to determine the regulation of the offense of insulting the government or state institutions based on the perspective of the right to freedom of expression and opinion. In addition, it also aims to compare the regulation of insulting offenses against the government or state institutions in Indonesia with other countries. The research is included in normative legal research using a statutory approach, conceptual approach, and comparative legal approach. The results show that the offence under discussion does not violate the right to freedom of expression and opinion because Article 240 of the National Criminal Code has clearly distinguished between the act of "insulting" and the act of criticizing the government, which is a right of expression. In addition, the offense is included in the complaint offense so that it cannot be prosecuted prior to a report. Moreover, the regulation of the offense of insulting the government or state institutions is still in line with the principle of limiting the right to freedom of expression and opinion as a derogable right. Because the act of insulting is included in acts that violate morals and public order, which are the limits of the guaranteed right
Village Fund Corruption Reflects Weak Integrity of State Apparatus
No full textThis study examines transparency challenges and corrupt practices in village fund management in Madiun Regency. Issues discussed include the culture of patronage, regulatory deficiencies, and the low capacity of village officials, all contributing to corruption. Using a qualitative descriptive approach, data were collected through stakeholder interviews and document analysis. The study's findings indicate that misuse of village funds has resulted in significant losses to the state and undermined public trust. The cases in Sukosari and Gemarang demonstrate a pattern of systemic corruption through budget inflation and unrealistic procurement. The findings underscore the need for integrated reforms strengthening oversight mechanisms, enhancing village official capacity, and fostering community participation to achieve transparent and accountable village governance in village fund management, in order to create a transparent and accountable village government

Kesepian pada Wanita Dewasa Awal: Ditinjau dari Coping Stress dan Dukungan Sosial
No full textAbstract
Early adulthood is a crucial stage marked by identity formation and social transitions. An increasing number of early adult women are delaying or forgoing marriage, potentially heightening feelings of loneliness. This study investigates the relationship between coping stress, social support, and loneliness in unmarried early adult women. Using a quantitative approach with the Spearman Rho correlation, data were collected from 159 participants. Results revealed a strong positive correlation between coping stress and loneliness (r = 0.755; p < 0.01), and a very strong positive correlation between social support and loneliness (r = 0.804; p < 0.01). These findings indicate that higher levels of coping stress and social support are associated with greater loneliness. This suggests that not just the presence, but the quality of coping strategies and social support may influence loneliness in unmarried early adult women.

Productivity Rating Method for Labor Productivity Analysis of Packaging Pressing Section, Case Study at PT. X Kudus
Full text linkHuman resource or workforce management to achieve profits in a company can be seen from the level of productivity of its workers. The Productivity Rating method is one method used to measure the level of labor productivity. The measure obtained from this method is the Labor Utilization Rate (LUR), where productivity measurements are not only calculated from the time used for the main work (input), but in calculating productivity also involves the time of the work contribution carried out by each worker. In the Productivity Rating method, worker activities are classified into 3 things, namely Essential Contributory Work, Effective Work, and Ineffective Work. The purpose of the research is to analyze the productivity of the packaging pressing department workers at PT X Kudus using the Productivity Rating method. The productivity measure obtained from this analysis is the Labor Utilization Rate (LUR). The results of the productivity rating analysis show that overall the LUR at PT. X Kudus's pressing department is 57.27%, which means that workers in the pressing department are working productively, although in the LUR analysis there is still one worker who is not working productively
