Abstract

This research addresses the challenge of declining soil fertility in Pamekasan, East Java, by proposing a machine learning approach to improve the accuracy of soil fertility classification and provide data-driven recommendations. Conventional methods like linear regression and expert systems are limited in capturing the complexity of soil variables, leading to less accurate results. Therefore, this study compares the performance of two machine learning algorithms, Random Forest and XGBoost, in classifying soil fertility levels based on nutrient content (N, P, K, and micronutrients) and soil pH. The dataset, consisting of 880 soil samples from Pamekasan, revealed an imbalance, with the high-fertility class accounting for only 39 samples. After data preprocessing, both models were evaluated. The Random Forest model achieved an overall accuracy of 90.34%, slightly outperforming XGBoost, which reached 88.64%. Random Forest demonstrated superior performance in detecting low-fertility land (recall 0.97) and medium-fertility land (precision 0.93, recall 0.88). For the high-fertility minority class, Random Forest showed better recall (0.60) than XGBoost (0.40), while maintaining perfect precision (1.00). The study concludes that Random Forest is the optimal model for classifying soil fertility in Pamekasan. These findings provide a basis for more precise, efficient, and sustainable fertilization recommendations, which are expected to help farmers optimize productivity and support the sustainability of the local agricultural ecosystem by reducing excessive fertilizer use.

Abstract

The research was conducted at the DKI Jakarta Provincial Government's Development and Environment Bureau with the aim of assessing the relationship between workload and job stress on employee performance. The approach applied was a quantitative method using statistical tools. The research data came from primary data, while the sample determination used a saturation technique. The analysis stages involved descriptive, data quality assessment, classical assumption testing, hypothesis testing, and calculating the coefficient of determination. The results of the analysis indicated that both workload and job stress partially contributed a significant impact on employee performance, as evidenced by the value (Sig.) of 0.002 for workload and 0.032 for job stress, both of which were smaller than 0.05. Furthermore, the results of the simultaneous analysis also confirmed a significant effect, indicated by the F value of 0.002. Based on this, it was concluded that the workload (X1) and job stress (X2) variables had a significant positive impact on employee performance (Y), both individually and combined, because the value (Sig.) of both met the criteria ≤ 0.05.

Abstract

In the world of higher education, lecturers are one of the main components in building quality and quantity. Good quality will give good results as well, to improve the quality of each lecturer, it is necessary to have an award given to lecturers from the campus so that it becomes a motivation for lecturers to improve the quality given to students and the community. Amik Mitra Gama is a private campus located in the Duri Riau area, in this case to improve the quality of education one of the steps taken is to give awards and appreciation to the best lecturers who will be selected every year. To realize this, we need an easy calculation system that is carried out in the form of ranking according to the final value, therefore a decision support system using the ARAS method is chosen because it is very appropriate for the selection process and provides convenience in the calculations which are determined based on ranking. The decision support system using the ARAS method uses 8 criteria that are set as a reference in determining the best lecturers, namely Recent Education, Lecturer Functional Position, Lecturer Certification, Number of Journal Publications, Roles in Research, Journal Publication History, Research Grants, and Community Service. There are 10 lecturers in the field of computers who will be used as alternative data with lecturer codes D01, D02, D03, D04, D05, D06, D07, D08, D09, D10. The results obtained from this study are the lecturer code D04 = 0.0974, D06 = 0.0965, D09 = 0.0932, D07 = 0.0903, D03 = 0.0901 was selected as the best lecturer in 2021/2022. So that the results of this study can help the campus to determine the best lecturers every year fairly and be selected based on rankings.

Abstract

Elementary school is the first level of education for students who have an important role in the development of behavior, skills and talents. Thus, the selection of the best primary school becomes something important for parents, because this will affect the future of their children in the future. In this regard, parents are faced with many choices of primary schools, especially in the Purworejo area for their children. This study aims to assist parents in determining the best primary school that is right for their children by using a Decision Support System. The method used in this research is MOORA. Multi Objective Optimization On The Basic Of Ratio Analysis (MOORA) is a method that can filter the best alternatives because this method is able to determine goals based on conflicting criteria on several constraints, so the use of this method is very appropriate to solve existing problems. This study uses 6 criteria that have been determined as a form of reference in determining the best elementary school, namely Accreditation, School Location, School Facilities, School Achievement, Professional HR (Teachers), and Number of Excellent Programs. There are 7 elementary schools that will be used as alternative data, all of which are taken from elementary schools in Purworejo. Of the 7 elementary schools taken, 3 elementary schools with school codes SK03 = 0.3382 , SK01 = 0.2922 , and SK02 = 0.2538 were selected to be the best elementary schools in 2022.

Abstract

The purpose of this study focuses on a comparative analysis of the effectiveness of online recruitment (e-recruitment) implementation at PT Cipta Mulia Adinugraha (CMA) by comparing the key metrics of Time-to-Hire (TTH) and Cost-per-Hire (CPH) between conventional and online recruitment periods. The secondary objective is to identify the impact of digital implementation on Quality of Hire. This research method uses a quantitative-comparative design with a case study approach. Quantitative data were collected from the Human Resources (HRD) Division reports of PT CMA during two one-year observation periods. Efficiency data were analyzed descriptively using comparative percentage change calculations. Qualitative data, derived from in-depth interviews with Talent Acquisition Managers and Staff, were used to strengthen the interpretation of the results. The results show a substantial increase in efficiency. The average TTH decreased by 42% (from 50 days to 29 days), while CPH was saved by an average of 35% (from Rp 5,000,000 to Rp 3,250,000). However, the surge in applicant volume post-digitalization poses new challenges related to mismatch ratios and has the potential to impact Quality of Hire if the in-depth screening process is not optimized. PT.CMA is recommended to balance the efficiencies achieved by integrating Artificial Intelligence (AI) features into its Applicant Tracking System (ATS) to improve competency screening accuracy, thereby achieving overall recruitment effectiveness.

Abstract

  ABSTRACT Universitas Amikom Yogyakarta Library provides discussion rooms to support students’ academic activities. However, the current borrowing process is still handled manually and via instant messaging, which is considered inefficient due to queues, unclear schedules, and the risk of recording errors. This study aims to design a web-based blueprint for a library discussion-room booking system using the Human-Centered Design (HCD) approach. The research method includes a literature study, system requirements analysis, system modeling using Unified Modeling Language (UML), menu structure design, and the development of a high-fidelity interface prototype. The results are a comprehensive system design consisting of a use case diagram, activity diagram, menu structure, and interface prototype as a reference for future implementation. The proposed blueprint defines booking rules limited to working days (Monday–Friday) and operating hours (08:00–16:00) with flexible booking duration within that range, while preventing schedule conflicts (double booking). In addition, the design includes an automatic cancellation rule when check-in is not confirmed more than 30 minutes after the scheduled start time, and the prototype evaluation is conducted through cognitive walkthrough and heuristic evaluation without direct involvement of end users [6][7].   ABSTRAK Perpustakaan Universitas Amikom Yogyakarta menyediakan ruang diskusi sebagai fasilitas pendukung kegiatan akademik mahasiswa. Namun, proses peminjaman ruang diskusi yang masih dilakukan secara manual dan melalui pesan singkat dinilai kurang efektif karena menimbulkan antrean, ketidakjelasan jadwal, serta potensi terjadinya kesalahan pencatatan. Penelitian ini bertujuan untuk merancang blueprint sistem peminjaman ruang diskusi perpustakaan berbasis web dengan pendekatan Human-Centered Design (HCD). Metode penelitian meliputi studi literatur, analisis kebutuhan sistem, perancangan sistem menggunakan Unified Modeling Language (UML), penyusunan struktur menu, serta perancangan prototipe antarmuka (high-fidelity prototype). Hasil penelitian berupa rancangan sistem yang komprehensif yang mencakup use case diagram, activity diagram, struktur menu, dan prototipe antarmuka sebagai acuan implementasi sistem di tahap pengembangan selanjutnya. Blueprint sistem yang dihasilkan menetapkan aturan booking hanya pada hari kerja (Senin–Jumat) dan jam operasional 08.00–16.00 dengan durasi peminjaman fleksibel dalam rentang tersebut, serta mencegah bentrok jadwal (double booking). Selain itu, rancangan mencakup aturan pembatalan otomatis apabila tidak ada konfirmasi check-in lebih dari 30 menit setelah waktu mulai, dan evaluasi prototipe dilakukan melalui cognitive walkthrough dan heuristic evaluation tanpa melibatkan pengguna akhir secara langsung [6][7].
