Integration of Field Data and Citizen Science in Spatial-Based Tropical Biodiversity Information Systems
Biodiversity monitoring in tropical regions is often constrained by limited field survey coverage and fragmented data. This study develops a spatial information system that integrates field data collected through an Android application, citizen science contributions from iNaturalist, and environmental indicators such as the Normalized Difference Vegetation Index (NDVI) and land cover. The integration process employs a spatial database and ETL mechanisms for data normalization, quality validation, and spatial joins with raster data. The implementation results demonstrate that the system is capable of displaying biodiversity distribution in an integrated interactive map. Although citizen science data provide significant contributions, challenges remain in terms of data quality, participation bias, and the protection of sensitive species. With appropriate methodological approaches, this system has the potential to serve as a supporting tool for biodiversity monitoring and data-driven conservation planning.

Integrating Peer Counselor Training in Psychological First Aid (PFA) to Reinforce University Counseling and Disability Support Systems
Psychological First Aid (PFA) is an essential competency for peer counselors to support mental health among university students. To strengthen students’ knowledge and readiness in providing early psychological support, a one-day Peer Counselor Training was conducted involving 22 psychology students (mean age = 20.73 years). The training consisted of lectures, video, case discussions, demonstrations, supervised roleplay, reflection, and assessments covering mental health concepts, psychological disorders, non-suicidal self-injury, suicidal ideation, suicide attempts, suicide, dynamics of interpersonal relationships, and the core principles of PFA. Pre- and post-training assessments showed a clear improvement in participants’ knowledge. Due to the non-normal distribution of the posttest scores, a Wilcoxon Signed-Rank Test was performed, yielding statistically significant results (Z = -4.12, p < 0.001). This finding indicates that the training effectively enhanced students’ understanding of PFA. Participants also expressed high satisfaction with the learning materials, simulations, and media used, suggesting that the training methods were engaging and useful for practical skill development. They recommended longer simulation sessions and more interactive case-based discussions for future training. Importantly, the training strengthens the role of students as active partners in campus mental health promotion. Trained peer counselors serve as an accessible first point of contact for fellow students, including those with disabilities who may face academic, emotional, or social barriers. Their presence supports early detection of distress, facilitates timely referrals to professionals, and complements the work of Counselling and Disability Service Unit (Unit Layanan Disabilitas/ULD). Through this initiative, the university’s commitment to inclusive, responsive, and student-centered mental health support is significantly reinforced.

Analysis of Road Damage Handling Priority Based on Pavement Condition (Case Study: National III Road, Kabat – Banyuwangi Segment)
Banyuwangi Regency is a leading tourism area designated as a National Tourism Strategic Area (KSPN), making the availability of adequate road infrastructure essential to support regional mobility and accessibility. However, traffic accidents have increased in recent years, particularly on the Jalan Nasional III segment from Kabat to Banyuwangi. This rise in accidents may indicate a correlation with the condition and performance of the road infrastructure. Therefore, a comprehensive evaluation of this segment is required, focusing on three main aspects, there are riding quality, pavement damage level, and drainage conditions as the basis for determining maintenance priorities. The study was conducted through field surveys, including measurements of Riding Quality, calculation of Total Distress Point (TDP), and assessment of drainage system performance in both directions. The analysis shows that the Kabat–Banyuwangi direction has several segments with low ride comfort (Poor), TDP values indicating light to medium maintenance needs, and some drainage points requiring maintenance. In contrast, the Banyuwangi–Kabat direction shows better and more stable conditions in terms of ride comfort, pavement damage, and drainage performance. These findings suggest that maintenance priorities should focus on the Kabat–Banyuwangi segments experiencing the most significant performance decline. This integrated evaluation approach is expected to provide a comprehensive basis for supporting more effective, efficient, and sustainable road maintenance decision-making.

Dynamical System Modeling of Dynastic Cycle with Optimal Control
In ancient China there are three model of society which is farmers, bandits and ruler. When the authority (rulers) is not there, the dynamics system of farmers and bandits become predator-prey interactions system. In here rulers play role on taxing the farmers and catching the bandits and then punish them. Thus, farmers are a sort of renewable resource which is exploited both by bandits and by rulers. In this paper, optimal control is applied to reduce the bandit’s population, by reducing it, the ruler population can also be reduced because the existing bandits can be conquered, so that the cost of running a government is more efficient because it can reduce the need for eradicating bandits from ruler. The type of the optimal control here is fixed time and free end point.

Evaluation of User Acceptance and Experience of the Coretax System Among Corporate Taxpayers in Indonesia
The rapid digital transformation in public administration has encouraged the Direktorat Jenderal Pajak (DJP) of Indonesia to implement the Coretax system as part of its modernization agenda for tax administration. This study aims to evaluate the level of user acceptance and experience of the Coretax system among corporate taxpayers in Indonesia using the Technology Acceptance Model (TAM) approach. The research focuses on examining the relationships between perceived ease of use (PEOU), perceived usefulness (PU), behavioral intention (BI), and use behavior (UB), with an additional variable (usage barriers) to explore external factors that may hinder technology adoption. The study employed a quantitative method involving a survey of 136 corporate taxpayers who actively use Coretax. Data were analyzed using descriptive statistics, regression analysis, and mediation testing through the PLS-SEM approach. The results indicate that all primary hypotheses (H1–H5b) are significantly supported (p < 0.05). PU emerged as the most dominant factor influencing BI and UB, while PEOU plays a significant role in shaping PU and BI. Behavioral intention acts as a full mediator between users’ perceptions and actual usage behavior. Moreover, perceived usage barriers negatively affect both PEOU and BI. These findings validate TAM within the Indonesian digital taxation context and highlight that successful Coretax implementation depends not only on system usability and benefits but also on continuous technical support and user training to ensure a positive digital experience.

Analysis of Teaching Material Needs for Short Story Writing with the Utilisation of Artificial Intelligence (AI) for High School Students
This research aims to develop short story writing teaching materials based on Artificial Intelligence (AI). Literacy skills are developed in various learning activities, one of which is writing, which can be linked to fictional stories in the form of short stories. This writing activity is related to the use of language in daily life, and the topics raised can be related to everyday experiences. Writing short stories requires a process of developing students' creativity. This process contains the concept that short story writing skills are not acquired instantly, but rather thru a step-by-step process with intensive and continuous practice, and requires students' active participation in the writing process. Writing short stories is not easy and can encounter obstacles such as developing ideas, describing the core of the story, setting, characters, plot development, and building dialog that fits the story and the characters being portrayed. One solution that can be implemented is providing teaching materials with the assistance of Artificial Intelligence (AI). The presence of AI-assisted teaching materials in writing short stories can help someone develop the ideas they want to turn into a short story, the general outline of the story, characters, setting, events, and dialog. This can help someone develop short stories with more varied, creative narratives tailored to each individual's experiences. Thru this AI-based learning material, one can utilize it and elaborate it into a form of self-understanding description that will later be developed or can become points in a specific schema format. The short story writing teaching materials created based on this needs analysis will later be developed, validated, and field-tested on a limited scale.

Evolution of the Intellectual Property Information System at the Kalimantan Institute of Technology Using the Waterfall Method and Design Thinking
Intellectual Property (IP) Management at the Kalimantan Institute of Technology (ITK) was previously hindered by manual processes using Google Forms and Excel that were inefficient and prone to errors, and by limited information systems. This research aims to evolve the ITK Intellectual Property Information System (SIM KI) to enhance data management efficiency at the backend and improve functionality and user experience at the frontend. The development methodology uses a structured Waterfall approach. The backend is developed with Node.js (Express) and PostgreSQL, while the frontend uses React JS with interface design based on Design Thinking. System verification is conducted comprehensively through Black Box Testing, White Box Testing, User Acceptance Testing (UAT), and the System Usability Scale (SUS). The evolution results show successful system implementation that now supports four types of IP (Copyright, Patent, Trademark, Industrial Design). Backend testing through unit testing validates the reliability of internal logic, while frontend testing demonstrates functional success (Black Box), good usability (SUS score 77.89), and significant user acceptance improvement (UAT score increased from 68% to 76%). The evolution of SIM KI successfully resulted in a more efficient, functional, and well-received digital platform, which implies increased effectiveness of IP management in the academic environment of ITK.

The Influence of a Meritocracy System on the Quality of Public Services
This study examines the relationship between the merit system and the quality of public services, with the work motivation of state civil apparatus (ASN) as a mediator, using a case study in the West Sumbawa Regency Government. The background of the study is based on the need to strengthen bureaucratic professionalism through recruitment, promotion, competency development, and talent management practices based on qualifications and performance, amidst implementation challenges at the regional level influenced by limited capacity and a patronage culture. The research aims to build an empirical understanding of the extent to which the merit system affects the quality of public services, both directly and indirectly, through increased work motivation. This study uses a quantitative cross-sectional approach with a Likert scale-based instrument to measure the dimensions of meritocracy, work motivation, and public service quality adapted from the SERVQUAL model. Data analysis was performed using Partial Least Squares-Structural Equation Modeling (PLS-SEM), testing construct validity and reliability, as well as the significance of direct and indirect paths. The findings show that all merit components—from recruitment to talent management—significantly influence the formation of a strong merit system, with the greatest impact coming from competency development and talent management. The established merit system contributes positively to public service quality, reflected in the dimensions of reliability, responsiveness, assurance, empathy, and tangibles, with work motivation proven to partially mediate this relationship. These results affirm the importance of integrating merit-based HRM policies with strategies to strengthen ASN motivation as a continuous effort to improve service quality and public trust.
