Abstract

Artikel ini menganalisis narasi dalam Kitab Ester dengan menyoroti bagaimana kisah tersebut membentuk dan merefleksikan konstruksi gender serta identitas etnis. Dengan menerapkan pendekatan kualitatif, penelitian ini menggunakan analisis naratif serta hermeneutika kritis untuk memahami kisah Ester dalam kerangka patriarki dan feminisme. Studi ini menyoroti identitas ganda Ester sebagai perempuan Yahudi dalam lingkungan Kekaisaran Persia yang patriarkal, dengan merujuk pada konsep interseksionalitas gender dan etnisitas sebagaimana dikemukakan oleh Kimberlé Crenshaw. Artikel ini berargumen bahwa Kitab Ester merepresentasikan simbol kuat perlawanan perempuan, yang menawarkan perspektif mengenai pengalaman perempuan di bawah kekuasaan imperial serta perjuangan yang terus berlangsung dalam menghadapi ketidakadilan gender. Berbagai interpretasi feminis terhadap sosok Ester yang mencakup dimensi keberanian hingga kepatuhan dikaji secara kritis guna mengungkap kompleksitas karakternya serta relevansinya terhadap wacana gender kontemporer.

Abstract

This study aims to explore the relationship between the fulfillment of spiritual needs and depression levels among members of the Coram Deo Christian community in Malang. A quantitative research design with a survey methodology was employed, involving 30 community members. The results reveal a significant negative correlation between the fulfillment of spiritual needs and depression levels, with a correlation coefficient of ? = -0.510 (p = 0.004). These findings suggest that higher levels of spiritual fulfillment are associated with lower levels of depression, indicating that spirituality may act as a protective factor against depression. Consequently, integrating the fulfillment of spiritual needs and community support within a holistic approach may serve as an effective strategy for the prevention and management of depression, particularly within migrant student communities.

Abstract

Salah satu persoalan urban perkotaan adalah kepadatan penduduk yang menyebabkan minimnya ruang sosial yang terpadu dan ramah bagi anak dan pemenuhan hak-hak dasar anak. Akibatnya anak-anak dalam kondisi rentan dan berpotensi mengalami kekerasan, eksploitasi, pelecehan dan pengabaian. Artikel ini menggunakan tafsir ideologis-sosiologis tentang penerimaan dan penolakan anak dalam penyambutan dan kehadirannya. Refleksi teologis ini menjadi pendukung bagi gereja-gereja, dan lembaga kristen untuk memberikan dukungan terhadap pelayanan kepada anak yang sejalan dengan program pemerintah mewujudkan kota layak anak (RPTRA), dan menggunakan RPTRA sebagai ruang sosial dan ruang pelayanan yang memberikan perhatian pada pemenuhan hak anak. Refleksi teologis ini juga menjawab dukungan pembangunan RPTRA dan pemanfaatan RPTRA sebagai ruang sosial dan ruang pelayanan untuk menghadirkan penerimaan Allah dan penyambutan Yesus Kristus kepada anak-anak untuk diterima, dihargai dan dicintai dan terbebas dari segala bentuk kekerasan, pengabaian, pelecehan dan eksploitasi. Pelayanan kepada anak yang lintas iman dan lintas generasi menghadirkan gambaran Allah di dalam Alkitab, memberikan dukungan terhadap penerimaan kepada anak untuk menjembatani konflik dan memulihkan sekat-sekat masyarakat urban akibat politisasi agama, gap lintas generasi. Refleksi ini memberikan pendasaran teologis yang mengasuh spiritualitas anak dalam gambaran Allah dan penerimaan Yesus Kristus yang inklusif  melalui berbagai jenis dan bentuk pelayanan gereja dengan memaksimalkan RPTRA.

Abstract

Rainfall forecasting is crucial in meteorological studies due to its significant impact on sectors such as agriculture, which is the main livelihood on Madura Island. This study aims to forecast rainfall on Madura Island using a hybrid approach that combines the Generalized Space-Time Autoregressive-X (GSTARX) model and Neural Network (NN). The data used consist of daily rainfall records from Bangkalan, Sampang, Pamekasan, and Sumenep, covering the period from January 2013 to December 2023. Data from January 2013 to September 2023 were used for training, while data from October to December 2023 were used for testing. The GSTARX model was employed to capture spatio-temporal patterns, while the NN was applied to learn the non-linear relationships in the residuals. The results show that the GSTARX model effectively captures rainfall patterns, though some differences remain compared to the actual data, with RMSE values of Bangkalan (1.514), Sampang (0.256), Pamekasan (0.477), and Sumenep (0.127). Meanwhile, the hybrid GSTARX-FFNN model achieved improved forecasting performance in Sampang (0.392), Pamekasan (0.679), and Sumenep (0.412), although Bangkalan recorded a higher RMSE (1.359). Overall, the GSTARX model proved more effective in forecasting rainfall on Madura Island, delivering smaller and more consistent prediction errors.

Abstract

Film Kukira Kau Rumah menampilkan representasi perpustakaan yang sarat maknaideologis, sehingga menarik untuk diteliti dalam kaitannya dengan persepsi publikterhadap perpustakaan kontemporer. Penelitian ini menggunakan pendekatankualitatif dengan metode analisis tekstual, mengacu pada teori representasi Stuart Halldan analisis tekstual McKee. Hasil penelitian menunjukkan bahwa perpustakaan dalamfilm direpresentasikan sebagai “kuburan ide” dan “museum buku.” Metafora “kuburanide” menggambarkan krisis literasi serta seruan agar perpustakaan menjadi ruanghidup yang mampu menghidupkan, mempelajari, dan mengaktualisasikan ide-ideyang terkandung di dalam koleksi. Sebaliknya, istilah “museum buku” merefleksikankritik terhadap aturan pembatasan peminjaman yang berpotensi mengerdilkan fungsiperpustakaan menjadi sekadar etalase pengetahuan. Analisis lebih lanjut menunjukkanbahwa perpustakaan dalam film ini tidak hanya tampil sebagai latar, tetapi juga sebagaitanda ideologis yang menyingkap ambivalensi institusi literasi, sekaligus menjadi simbolresistensi generasi muda terhadap krisis literasi dan dominasi budaya digital. Penelitianini menegaskan urgensi revitalisasi peran perpustakaan sebagai ruang interaktif yangmendukung literasi kritis, pengembangan intelektual, dan pertumbuhan generasimilenial.

Abstract

Manajemen stok bahan baku dalam usaha kuliner menghadapi tantangan besar akibat fluktuasi permintaan harian yang tidak menentu. Akibatnya, Warung Makan Dower kesulitan untuk mengelola stok ayam potong mengakibatkan seringnya terjadi kelebihan atau kekurangan stok ayam potong. Warung Makan Dower, yang mengandalkan ayam potong sebagai bahan utama dalam menu utamanya, membutuhkan sistem prediksi yang mampu merespons dinamika tersebut secara presisi. Penelitian ini mengembangkan model prediksi permintaan ayam potong berbasis Fuzzy Time Series Markov Chain (FTS-MC), menggunakan 1101 baris data penjualan harian aktual dari Mei 2022 hingga Mei 2025, termasuk hari-hari tanpa penjualan untuk menjaga kesinambungan waktu. Model dibangun melalui tahapan pengumpulan dan pembersihan data, proses fuzzifikasi menjadi 15 interval, pembentukan matriks probabilitas transisi, serta estimasi permintaan untuk tujuh hari ke depan. Hasil prediksi diintegrasikan ke dalam sistem web, yang dapat diakses langsung oleh pengelola warung untuk mendukung pengambilan keputusan stok secara real time. Evaluasi akurasi dilakukan dengan metode Mean Absolute Percentage Error (MAPE), menghasilkan nilai MAPE rata-rata sebesar 4,75%, menunjukkan performa prediksi yang sangat baik. Perbandingan dengan konfigurasi lainnya memperlihatkan nilai MAPE jauh lebih tinggi, yaitu 66,06% (3 interval), 45,58% (6 interval), 17,09% (9 interval), dan 25,69% (12 interval). Dengan hasil ini, metode FTS-MC terbukti efektif dalam mengoptimalkan peramalan penjualan harian berbasis data historis.

Abstract

Productivity in the production process is very influential and become a benchmark for success in every industry. Healthy productivity can increase customer satisfaction because the waiting time for production is not too long from the expected target. The need for improvement in the system is one way to increase production at PT ABC. From the observations results showed the activity percentage of production administration operator were very high. It was at 98.727%. Production per day was less than the company target, the expected target was 40 batches per day, but in fact, it only produced 35 batches average per day. There were three proposed scenarios to fix the performance at Production Unit PT ABC. The Third Scenario was the choice that had highest result for daily production, while Scenario Second was the choice with the highest results if using weekly and annual running times references.

Abstract

This study aims to analyze the narrative of Genesis 2:4 b-3:24 using Tzvetan Todorov's narratology theory, which consists of five phases: equilibrium, disruption, recognition, repair, and new equilibrium. This study uses a descriptive-qualitative approach to reveal the socio-theological aspects present in the text. The findings show that the narrative structure reflects a cycle of harmony and conflict, starting with the initial equilibrium of the relationship between God, humans, and creation. Disruption occurs through the serpent's temptation, which leads to human transgression and subsequent acts of recognition. The narrative continues to repair, where consequences are imposed, and finally reaches a new equilibrium that illustrates God's justice and mercy in providing a new beginning for humans. This analysis not only enhances the understanding of the socio-theological implications of the text but also invites a re-evaluation of traditional interpretations of humanity's expulsion from Eden and the ongoing relationship between society, creation, and God.   Abstrak Penelitian ini bertujuan untuk menganalisis narasi Kejadian 2:4 b-3:24 menggunakan teori naratologi Tzvetan Todorov, yang terdiri dari lima fase: equilibrium, disruption, recognition, repair, dan new equilibrium. Penelitian ini menggunakan pendekatan deskriptif-kualitatif untuk mengungkap aspek sosial-teologis yang ada dalam teks. Temuan menunjukkan bahwa struktur narasi mencerminkan siklus harmoni dan konflik, dimulai dengan equilibrium awal hubungan antara Tuhan, manusia, dan ciptaan. Disruption terjadi melalui godaan ular, yang mengarah pada pelanggaran manusia dan selanjutnya ada aksi recognition. Narasi berlanjut ke repair, di mana konsekuensi dipaksakan, dan akhirnya mencapai new equilibrium yang menggambarkan keadilan dan belas kasihan Tuhan dalam memberikan awal yang baru bagi manusia. Analisis ini tidak hanya meningkatkan pemahaman tentang implikasi sosial-teologis dari teks tetapi juga mengundang evaluasi ulang terhadap interpretasi tradisional mengenai pengusiran manusia dari Eden dan hubungan yang berkelanjutan antara umat manusia, ciptaan dan Tuhan.

Abstract

Thalassemia is an inherited blood disease which lacks hemoglobin, the protein that is carrying oxygen to the body. The severe one is called Thalassemia Major which needs special care about blood transfusion. The use of rule-based method to create an inference as the first diagnosis of Thalassemia Major is not effective as rules have to be achieved from long interview with the medical personnel. This research aims to create a model based on decision tree for first detection of Thalassemia Major. The dataset is obtained by interview of Thalassemia symptoms and primary data of medical records from a hospital. Classical decision tree models used are ID3, C4.5 and CART. The models are evaluated by Train-Test Split consists of 70% training and 30% testing data and k-Fold Validation for checking model’s overfitting or underfitting. The output of this research is a final tree model from the best performance of decision tree models. The final result shows that C4.5 has the best performance with accuracy 100% and not overfitting or underfitting. Also, C4.5 performs feature selections to its tree modeling to simplify the inference. In brief, decision tree based modeling is effective to be used as first detection of Thalassemia Major by interview symptoms with generating automatic rules from its tree model.
