This study aims to examine the service performance of the Women’s Empowerment and Child Protection Agency (DPPPA) of Gorontalo Regency in handling cases of violence against children. The study focuses on addressing the service performance from several aspects; (a) productivity, (b) service quality, (c) responsiveness, (d) responsibility, and € accountability. This study was conducted based on the persistently high number of cases of violence against children, which require effective, responsive, and accountable public service handling from the local government. This study employed a qualitative method with a descriptive approach. Data collection techniques included observation, interviews, and documentation, while data analysis used the Miles and Huberman model, consisting of data reduction, data display, and conclusion drawing. The findings indicate that service productivity is fairly good, as reflected in a clear case-handling flow, though it remains constrained by limited human resources and cross-sector coordination. Service quality is considered positive in terms of empathetic attitudes and the availability of private service spaces; however, the quality of physical facilities and the availability of professional personnel still need improvement. Officers’ responsiveness is relatively quick at the initial stage, but follow-up information on cases is not consistently provided. Responsibility for implementing procedures is in accordance with standard operating procedures, although completion times are often lengthy. Meanwhile, administrative accountability functions well, but the transparency of information to victims still needs to be strengthened.

Bali, as an international tourism destination, serves as a space for cross-cultural interactions that require effective communication skills, particularly in the hospitality sector. Hotel Masa Inn serves predominantly international guests, requiring front office staff to adapt to cross-cultural communication. This study aims to analyze the process of cross-cultural communication adaptation between Hotel Masainn employees and international guests through the perspective of Willingness to Communicate (WTC). A descriptive qualitative approach was employed using observation, structured interviews, and document analysis. Informants were selected purposively from front office staff. The findings indicate that communication adaptation is carried out through basic English proficiency, the use of nonverbal communication, active interaction, and intrinsic motivation to improve language skills. However, this process also faces challenges in the form of communication anxiety and situational pressure, particularly when dealing with repeater guests. Within the WTC framework, employees’ willingness to communicate is influenced by self-confidence, motivation, anxiety, and interactional context, which collectively contribute to service quality and international guest satisfaction.

General elections constitute a fundamental pillar of Indonesia’s democratic system, functioning as a mechanism for the exercise of popular sovereignty and the protection of citizens’ voting rights. During the 2024 Regional People’s Representative Council (DPRD) election in Tarakan City, the Badan Pengawas Pemilu Kota Tarakan recorded twelve reports of alleged administrative violations throughout the electoral stages, including during the national vote recapitulation process. Of these reports, three allegations were proven, involving violations related to the Additional Voter List, the Special Voter List, and the eligibility requirements of candidates running for the Tarakan City DPRD in 2024. Essentially, election law enforcement serves as a safeguard to ensure fairness, legal certainty, and the protection of citizens’ constitutional right to vote. This study aims to examine the implementation of legal enforcement mechanisms against administrative violations in the 2024 Tarakan City DPRD election. A socio-legal research approach was employed to analyze both normative regulations and their practical application. Referring to Peraturan Bawaslu Nomor 8 Tahun 2022 concerning the Settlement of Administrative Violations of General Elections, the findings indicate that the Tarakan City Bawaslu holds authority in adjudicating and imposing sanctions on proven violations. As a result, one candidate, Erick Hendrawan Septian Putra, was disqualified from Electoral District 1. Furthermore, sanctions were imposed on the chairpersons and members of Polling Station 88 in Karang Anyar and Polling Station 2 in Pamusian for failing to carry out their duties as voting organizing groups in the election and subsequent processes.

Disputes over unpaid insurance claims are a problem that frequently arises in insurance practice and can harm consumers both financially and psychologically, while also reducing public trust in the insurance industry. Such disputes are generally triggered by differing interpretations of policy provisions, alleged breaches of the good-faith principle, and administrative obstacles, which ultimately lead to civil conflicts between the insured and the insurer. To provide access to dispute resolution that is faster, fairer, and more affordable than litigation, the Financial Services Authority (Otoritas Jasa Keuangan/OJK) established the Alternative Dispute Resolution Institution for the Financial Services Sector (Lembaga Alternatif Penyelesaian Sengketa Sektor Jasa Keuangan/LAPS SJK) through OJK Regulation No. 61/POJK.07/2020. This study aims to analyze the mechanism for resolving disputes over unpaid insurance claims through LAPS SJK and to assess its effectiveness in providing legal protection and legal certainty for consumers. The research method employed is normative legal research using a statutory approach and a conceptual approach, through an examination of primary, secondary, and tertiary legal materials related to contracts, insurance, consumer protection, and alternative dispute resolution. The findings show that LAPS SJK has the authority to handle civil disputes in the financial services sector, including insurance disputes, provided that the parties have a written agreement and have first pursued internal dispute resolution (Internal Dispute Resolution/IDR). Dispute resolution at LAPS SJK is conducted through mediation and arbitration. Mediation is facilitated by a mediator to encourage the parties to reach a settlement agreement, which may be reinforced into a Deed of Settlement (Akta Perdamaian) that is final, binding, and enforceable. If mediation fails, arbitration offers a more determinative resolution through a final and binding award that can be enforced after being registered with the District Court. Overall, LAPS SJK is considered effective because its procedures are structured, time-bound, and provide a fee waiver for mediation in retail and small-claim cases up to IDR 750,000,000. However, its effectiveness remains conditional, as it depends on the existence of a written agreement between the parties, the obligation to undergo IDR, and good faith in the mediation process.

This study aims to analyze the influence of incentives and physical work environment on employee performance with motivation as a mediating variable at the Denpasar City Cultural Office. This study uses a quantitative approach with a survey method. The research population was all employees of the Denpasar Cultural Office totaling 54 people, all of whom were sampled using saturated sampling techniques. Data were collected through a questionnaire with a Likert scale and analyzed using Structural Equation Modeling based on Partial Least Square (SEM-PLS). The results of the study showed that incentives had a positive and significant effect on employee performance, while the physical work environment did not have a significant effect on employee performance. In addition, motivation has a positive and significant effect on employee performance. Mediation testing showed that motivation was able to mediate the influence of incentives on employee performance, but was unable to mediate the influence of the physical work environment on employee performance. These findings indicate that improving employee performance is more effective through providing the right incentives and increasing work motivation compared to improving the physical work environment alone.

The purpose of this study is to examine the implementation of employment agreements as one of the means of providing legal protection for workers’ rights. The research method employed in this study is normative juridical, utilizing primary and secondary legal materials obtained through the analysis of statutory regulations, legal scholars’ opinions, as well as books and journals relevant to the subject under study. The results of the study indicate that employment agreements, as a form of preventive legal protection for workers’ rights, are a consequence of the application of the welfare state concept, thereby requiring the state to intervene in employment relationships arising from such agreements. This form of intervention can be observed in Law Number 13 of 2003 concerning Manpower. The provisions contained in this law, particularly Article 54 paragraph (1) of Law Number 13 of 2003 concerning Manpower, constitute a form of preventive legal protection, especially in points (e) and (f), as they regulate economic rights as well as the rights and obligations of workers. These provisions provide protection and serve as a form of legal certainty that safeguards workers from the beginning of their employment. The obstacles encountered in the implementation of employment agreements as a preventive means of protecting workers’ rights are divided into three factors: regulatory factors, legal culture factors, and legal structure factors.

This study aims to analyze the comparison of the impact of financial and non-financial compensation effectiveness on turnover intention among Generation Z employees. The high turnover rates within Generation Z, despite receiving adequate financial compensation, indicate a shift in their preferences regarding the workforce. Generation Z tends to seek more than just financial compensation, such as flexibility, a supportive work environment, and opportunities for growth. The method used in this study is a literature review, analyzing various relevant scholarly journals related to strategic compensation, Generation Z characteristics, and turnover intention. The research findings show that non-financial compensation has a more significant impact in reducing turnover intention among Generation Z compared to financial compensation. Therefore, companies need to focus on aspects such as work-life balance, career development opportunities, and an inclusive and supportive work culture. These findings provide valuable insights that companies should adopt a more holistic reward approach through the total rewards concept, which includes both financial and non-financial compensation, in order to enhance loyalty and retention of Generation Z employees in the long term.

This study discusses the design and simulation of an automatic lighting system based on a photodiode sensor using an Arduino Uno microcontroller as the main controller. The system is designed to detect changes in ambient light intensity and automatically control the lamp without human intervention. The photodiode sensor is used as a light detector that converts light energy into an analog electrical signal, which is then processed by the Arduino to determine bright or dark conditions. The output from the Arduino subsequently controls a relay module that functions as an electronic switch to connect or disconnect the current to the light bulb. The research method employed is an experimental approach, which includes system planning, hardware design, software programming, simulation using Proteus, and system performance testing. The simulation results indicate that the system operates as expected, where the lamp automatically turns on when the light intensity decreases and turns off when the ambient brightness increases. This system is expected to improve electrical energy efficiency and provide ease of operation for lighting control, particularly in public facilitiesand workplace environments.

This study aims to describe and analyze the understanding of the faithful and the implementation of Eucharistic liturgical gestures at Saint Christopher Parish, Siborongborong. Liturgical gestures such as the sign of the cross, standing, sitting, kneeling, and striking the chest are essential elements of active participation in the Eucharistic celebration. These gestures are not just physical actions but carry profound spiritual significance. This research employed a descriptive qualitative approach, with data collected through participant observation, in-depth interviews, and documentation. The findings reveal that the faithful’s understanding of the symbolic meaning of these gestures remains limited, which leads to a tendency to perform them mechanically without deep spiritual reflection. This lack of understanding results in a disconnect between the physical actions and their intended spiritual effects. Nevertheless, in practice, the faithful generally follow these gestures in accordance with the liturgical norms of the Church. Therefore, the study emphasizes the need for continuous and contextual liturgical formation programs. These programs should aim to deepen the awareness and spiritual engagement of the faithful in the Eucharistic celebration, ensuring that the gestures are not just performed but fully understood and internalized.

This study explored how a teacher’s writing habit functions as emotional expression within a demanding teaching routine. Specifically, it examined four aspects like writing as emotional release, writing as reflective practice, writing within a demanding teaching routine, and writing as an emotional coping strategy. A qualitative single-case study design was employed. The participant was one female teacher at SD Negeri 060 Pekkabata, Polewali Mandar, Sulawesi Barat, who had a very hectic schedule including full-time teaching, administrative duties, and private tutoring. Data were collected through semi-structured interviews conducted via Zoom and WhatsApp chat, as well as document analysis of the teacher’s syllabus, lesson plans, blog, Instagram posts, journal book, and mobile phone notes. Thematic analysis was used to analyze the data. The findings revealed that writing served as a powerful emotional release, helping the teacher process anxiety and accept difficult situations. Reflective writing occurred primarily during professional training periods and motivated her to improve classroom practice. Despite her demanding routine, the teacher maintained a writing habit by using multiple platforms, writing during natural breaks, and prioritizing short, happiness-focused notes. She considered writing equally effective as talking to others for emotional expression and strongly recommended writing to fellow teachers. The study concludes that a flexible writing habit focused on emotional release and small positive moments can be a sustainable, low-cost coping strategy for teachers facing overwhelming professional demands. These findings have implications for teacher well-being program and teacher education.

This study aims to explore the role of pet attachment among cat owners in Palembang, focusing on how emotional bonds are formed, interpreted, and influence psychological well-being. A qualitative approach was employed using purposive sampling to select two main participants who had high interaction intensity with their cats, along with additional informants from family members and neighbors. Data were collected through in-depth interviews, observations, and documentation, then analyzed thematically with source triangulation to ensure validity. The findings reveal that pet attachment develops through daily interactions such as feeding, cleaning, playing, and monitoring the cat’s health. Cats are perceived not only as domestic animals but also as companions that provide psychological comfort, emotional support, and stress reduction. Factors shaping attachment include emotional needs, intensity of daily interaction, empathy toward the pet’s condition, long-term caregiving commitment, and the perception of cats as significant companions. The duration of ownership strengthens attachment quality, while the loss of a pet triggers profound grief comparable to losing a family member. Moreover, pet attachment influences family dynamics and social identity, portraying owners as caring and empathetic individuals. In conclusion, pet attachment among cat owners in Palembang is a complex psychological phenomenon involving emotional, social, and behavioral dimensions. The relationship between humans and cats extends beyond utilitarian functions, evolving into deep affective bonds that serve as coping mechanisms and psychosocial support in urban life. These findings enrich the literature on human-animal relationships and highlight the therapeutic and emotional value of pets in modern society.

The problem of urban flooding is a growing issue due to high population density, increasing volumes of plastic waste, and the reduction of water absorption areas. The use of conventional paving blocks, which are impermeable, further exacerbates flooding conditions because they do not allow water to infiltrate into the soil. This study aims to develop an innovative plastic waste-based paving block incorporating rice straw and sugarcane bagasse, along with the integration of phytoremediation concepts as a solution for urban flood mitigation. The method employed was an experimental approach involving the following stages: material preparation, plastic incineration, material mixing, molding, and testing of water absorption capacity and compressive strength. The results showed that paving blocks with a combination of plastic waste, rice straw, and sugarcane bagasse had the highest water absorption rate of 34% and compressive strength of 21 kg/cm², meeting SNI standards. The addition of natural materials containing silica was proven to enhance the material’s porosity and strength. Additionally, the application of phytoremediation using water hyacinth has the potential to improve the quality of water seeping into the soil. Thus, this phytoremediation-based paving block innovation can serve as an effective alternative solution to reduce flood risks while supporting sustainable waste management and environmental stewardship.

Fertilization serves as a fundamental component of crop cultivation, wherein the application of mineral nutrients is crucial for plant nourishment, facilitating various physiological processes critical for growth and development. The objective of this study is to establish an optimal recommended dosage that enhances cabbage growth and yield. The experimental design employed in this study was a randomized block design with four replications. The treatments consist of seven fertilization levels, as follows: No fertilization with nitrogen (N), phosphorus (P), or potassium (K) (P0), reference fertilization (P1), 0.5 dose of unbalanced compound fertilizers (P2), 0.75 dose of unbalanced compound fertilizers (P3), 1.0 dose of unbalanced compound fertilizers (P4), 1.25 dose of unbalanced compound fertilizers (P5), and 1.5 dose of unbalanced compound fertilizers (P6). The experiment indicated that the application of unbalanced compound fertilizers enhances cabbage plant growth, as evidenced by increased plant height and leaf number compared to the control treatment. Additionally, fertilization improves yield components relative to untreated plants. The application of 0.5 doses of unbalanced compound fertilizers proves agronomically effective, yielding the highest relative agronomic effectiveness at 169%, meaning a 1.69-fold increase in yield. Economically, the same dosage is also highly beneficial, achieving the highest R/C ratio of 2.35 and generating a profit of Rp. 14,365,150. The study results confirm that unbalanced compound fertilizers were both agronomically effective and economically advantageous. The recommended dosage for cabbage cultivation is 134 kg/ha, applied in two stages: 50% at 1 WAT (weeks after transplanting) and the remaining 50% at 4 WAT.

The coal mining industry requires accurate stockpile volume measurements for inventory and production reporting. Conventional methods have limitations in accuracy, efficiency, and safety. This study compares the accuracy and efficiency of coal stockpile volume measurements using a Terrestrial Laser Scanner (TLS) Leica MS60 and an Unmanned Aerial Vehicle (UAV) DJI Matrice 4E, validated by the ASTM D6172-98 standard. Conducted on five Run of Mine (ROM) coal stockpiles covering 13,500 m² at PT XYZ, Lahat, South Sumatra, the TLS method used 43 scan positions, while the UAV employed 430 aerial images with specific flight parameters. Data were processed using Leica Infinity, Surpac, and Agisoft Metashape. The results showed volumes of 94,076 m³ (TLS) and 94,965 m³ (UAV), with a difference of 889 m³ (0.95%). Volume deviations ranged from 0.48% to 1.89%, with an average of 1.42%, all within the ASTM tolerance (<2%). Time efficiency analysis revealed that the UAV method required 200 minutes (3.33 hours), saving 63.3% (approximately 6.17 hours) compared to the TLS method (570 minutes). The largest efficiency gain occurred during field data acquisition, with an 85% reduction in time. This study confirms UAV photogrammetry as a valid, accurate, and efficient alternative for coal stockpile volume measurement in mining.
