2026-07-24T17:59:33+07:00

PT Semen Padang, as a company in the cement industry, has implemented Green Supply
Chain Management (GSCM); however, its implementation still faces various operational
challenges. This study aims to identify contradictions in the implementation of GSCM and
to determine priority improvement strategies that can be applied effectively. The methods
used in this study are a combination of Theory of Inventive Problem Solving (TRIZ) and
Decision-Making Trial and Evaluation Laboratory (DEMATEL). The identification of
contradictions was carried out through internal questionnaires using the TRIZ approach
and resulted in nine contradictions across the aspects of green purchasing, green
manufacturing, and green distribution. Based on these contradictions, inventive solutions
were formulated and further analyzed using DEMATEL to map cause-effect relationships
and determine strategic priorities. The results indicate that strategy (A2) in the green
purchasing aspect and strategy (G4) in the green manufacturing aspect are the main cause
factors with the strongest influence, with 𝑅􀯜 − 𝐶􀯜 values of 1.166 and 1.489, respectively.
These priority strategies are expected to enhance the effectiveness of GSCM
implementation at PT Semen Padang in a sustainable manner

Rancang Bangun Sistem Informasi Rekam Medis Santri Terintegrasi Berbasis Web Menggunakan CodeIgniter 4

2026-07-24T17:59:34+07:00

The Health Services at the Salafiyah Syafi'iyah Sukorejo Islamic Boarding School have
currently implemented an electronic medical record (EMR) system. However, in its execution, the
system requires further development as it is not yet perfectly integrated across service units. The
separation of data access between the Boys' Satellite Clinic and the Girls' Satellite Clinic causes
operational barriers since staff at the Central Clinic must manage data through different platforms,
leading to administrative inefficiencies in student referral times and non-real-time data
synchronization. Furthermore, the current system lacks automated data interconnection from
registration to the doctor's unit and requires improvements in access rights management and
activity logs. To address these issues, a web-based integrated EMR platform was developed using
the CodeIgniter 4 framework, consolidating all service units into a single unified interface based
on the Student Identification Number (NIS). NIS is utilized as the primary search parameter due to
its unique nature (primary key) to anticipate the high probability of identical names among
thousands of students, thereby preventing the risk of interchanged medical records. The system

development follows the Waterfall method. The testing results indicate that the developed system
successfully unifies data access from satellite units to the central unit, automates registration-todoctor
data flows, and provides referral notification features before students arrive at the Central
Clinic. The implementation of the Model-View-Controller (MVC) architecture in CodeIgniter 4 is
proven to deliver a responsive web application execution performance and simplifies centralized,
secure, and accurate student medical record data management.

Optimasi Biaya Distribusi pada UMKM Produsen Keripik Pisang Lokal melalui Model Transportasi Menggunakan LINGO

2026-07-24T17:59:34+07:00

Distribution is one of the key activities in the operations of Micro, Small, and Medium Enterprises
(MSMEs) because it directly affects operational costs and business competitiveness. Some
MSMEs, such as Dapur Mama, still determine distribution patterns based on habitual practices
without quantitative calculations, which may lead to cost inefficiencies. This study aims to optimize
the distribution cost of Keripik Pisang Jawara products using a transportation model approach.
The method applied is Integer Linear Programming (ILP), solved with the assistance of LINGO
software. Research data were obtained through interviews with the MSME management, including
warehouse capacity, demand at each destination, and unit distribution costs. The results show that
the transportation model can determine an optimal distribution pattern that minimizes total
distribution costs without violating capacity and demand constraints. The optimal solution yields
a minimum total distribution cost of 20,940 cost units. Therefore, the ILP-based transportation
model is proven effective in improving distribution cost efficiency and can serve as a decisionsupport
tool for MSMEs.

Analisis Kinerja Distribusi Tempe UMKM Menggunakan Discrete Event Simulation: Studi Kasus Indragiri Hulu

2026-07-24T17:59:34+07:00

The tempeh distribution system in micro, small, and medium enterprises (MSMEs) often faces
imbalances in internal process capacity, leading to increased waiting times and order backlogs.
This study aims to model and analyze the performance of the tempeh distribution system in
Indragiri Hulu Regency using a Discrete Event Simulation (DES) approach. The simulation model
was developed using ProModel software to represent the operational flow of order receiving,
packaging, inspection, and delivery processes based on actual operating conditions. The analysis
was conducted using a baseline scenario and one proposed improvement scenario, with
performance indicators including location utilization, waiting time, and work in process (WIP).
The simulation results indicate that in the baseline scenario a bottleneck occurs at the packaging
process, characterized by a very high level of location utilization. The proposed scenario reduces
the workload pressure on the packaging stage and improves the distribution of system workload,
although capacity utilization in the inspection and delivery stages remains relatively low. These
findings demonstrate that the DES approach is effective for identifying system bottlenecks and
evaluating improvement alternatives in MSME-scale tempeh distribution systems.

Student Perceptions Of AI-Based Decision Support Systems: A Descriptive Statistical Analysis

2026-07-24T17:59:35+07:00

The rapid development of artificial intelligence (AI) has influenced many aspects of students’ academic
activities, especially in decision-making processes. Many university students now use AI-based tools to help
them understand assignments, generate ideas, and evaluate information during their studies. This study aims
to examine students’ reliance on AI-based decision support systems and identify several related factors,
including trust and critical thinking. A quantitative survey method was used in this research, and data were
collected from 60 university students from different academic backgrounds in the Jabodetabek area through
an online questionnaire distributed using Google Forms. The collected data were analyzed using descriptive
statistics. The findings showed that AI tools were widely used among students, with many respondents
demonstrating moderate to high levels of reliance on AI systems. Although students tended to trust AIgenerated
outputs, many respondents still evaluated the information critically before using it in academic
tasks. However, some respondents also believed that excessive AI usage could reduce independent thinking
abilities. Overall, the findings suggest that AI provides both benefits and potential risks in academic contexts.
Therefore, students should use AI in a balanced and critical manner so that technology can support learning
without reducing independent thinking and decision-making abilities.

Role of Recommendation Systems in Digital Music Streaming Platforms: User Decision-Making Among Sampoerna University Students

2026-07-24T17:59:35+07:00

This study explored the influence of recommendation systems in digital music streaming platforms on the decision-making processes of students at Sampoerna University. Utilizing a socio-technical framework, the research examined the tension between algorithmic efficiency and user exploration. Data were collected via a quantitative survey of 41 students, which revealed that while platforms like Spotify (80.5%) and YouTube Music (51.2%) were dominant, users experienced a distinct "algorithmic paradox." Although the most frequent rating for recommendation accuracy was an 8 out of 10 (reported by 41.5% of respondents), a significant 68.3% of students reported experiencing algorithmic boredom due to repetitive suggestions. These findings suggested that current systems, while effective at reducing cognitive load through features like auto-play (68.3%) and personalized playlists (53.7%), often trapped users in "filter bubbles" or "taste tautologies." The study concluded that the next generation of music Information System must evolve beyond simple predictive accuracy to incorporate context-aware diversity and serendipity, thereby balancing the efficiency of automation with the human need for discovery and autonomy.
