Abstract

Remaja merupakan suatu pelayanan kategorial yang menyasar kelompok usia antara anak-anak (sekolah minggu) dan pemuda. Tekanan stereotip, ekspektasi tinggi tanpa dukungan memadai, dibarengi dengan perubahan masif akibat kemajuan teknologi dan informasi dapat memicu permasalahan kesehatan mental generasi muda jika tidak dikelola dengan bijak. Tantangan lain yang dihadapi adalah mengenai spiritualitas remaja. Persekutuan Gereja-gereja di Indonesia (PGI) melihat perlunya mengadakan kegiatan bagi remaja dan pendamping/pembina remaja sebagai platform untuk memperlengkapi para remaja dan pembina dengan berbagai pengetahuan dan kapasitas yang diharapkan mampu membekali remaja dan pembina dalam pelayanan dan kehidupan berbangsa sehari-hari. Pendampingan yang dilakukan oleh para ahli di UKSW meliputi isu-isu seputar perkembangan psikologis, pengembangan bakat-minat, kecerdasan buatan dan implementasi dalam pelayanan serta gerakan cinta lingkungan lewat aksi tanam pohon di desa. Hasilnya, para peserta mendapatkan pengalaman berharga yang tampak dalam hasil survey kepuasan dimana mayoritas responden puas terhadap pendampingan dan 100 % responden memperoleh tambahan pengetahuan.

Abstract

This paper presents bidirectional long short-term memory (BiLSTM) OptiFlow, an optimized deep learning model designed to predict the financial health of cooperatives using key financial ratios: debt to equity ratio (DER), net profit margin (NPM), and return on equity (ROE). By leveraging a BiLSTM architecture combined with an optimal decayed learning rate, this model aims to enhance forecasting accuracy. The proposed model was tested against three established methods—recurrent neural network (RNN), long short-term memory (LSTM), and gated recurrent unit (GRU)—and evaluated using mean absolute error (MAE), mean absolute percentage error (MAPE), and mean squared error (MSE) metrics. Results indicate that BiLSTM OptiFlow outperforms the other models across all key indicators. This research offers a robust approach to cooperative financial forecasting, with significant implications for decision-making processes in cooperative management.

Abstract

Employee performance appraisal is one part of human resource activity, to maintain the quality and performance of its employees. Satya Wacana Christian University (SWCU) has also implemented the system, especially for its non-academic employees. The Employee Assessment Process in SWCU has been done by filling out a DP3 form manually, based on the evaluation from the supervisor. The manual assessment process takes a lot of time, because of how many employees need to be evaluated and the lack of objectivity in the assessment. Hence, this research is being done with a purpose to map out and implement a web-based performance assessment information system for the employees, which can then be used to assess those employees’ performance using a computerized system. This research is done to design an information system of performance assessment by applying Technique for Others Reference by Similarity to Ideal Solution (TOPSIS) method so that the assessment process can be done more objectively, quickly, and more importantly easily especially for the multi-criteria assessment process.
