The application of machine learning, particularly the *Convolutional Neural Network* (CNN) method, has experienced rapid development in the medical field. Through the process of image data grouping, CNN is capable of classifying based on the similarity of characteristics and attributes of the images. This capability is highly beneficial in the healthcare sector, especially in differentiating chest X-ray images. This study aims to evaluate the DenseNet architecture while applying it to classify Covid-19 disease by utilizing 98 chest X-ray images as training data. The test results showed that the average *loss* value on the training data was 0.8621, with an average accuracy of 0.6950. Meanwhile, the average *loss* value on the validation data was recorded at 1.0682, with an average accuracy of 0.6399. From these results, it can be concluded that the model performed better on the training data than on the validation data, indicating the occurrence of *overfitting*. Therefore, further adjustments to the model are necessary to improve its performance on the validation data

Toko Ahmad Adam adalah toko sembako yang menyediakan kebutuhan pokok seperti beras, minyak goreng, mie instan, dan gula. Pengelolaan stok yang masih dilakukan secara manual menyulitkan pemilik toko dalam menetapkan prioritas pengadaan barang. Ketiadaan sistem klasifikasi stok menyebabkan ketidakseimbangan antara kebutuhan dan ketersediaan barang, sehingga berisiko terjadi kekurangan atau kelebihan stok. Penelitian ini bertujuan membangun model klasifikasi stok guna mengoptimalkan pengelolaan persediaan. Metode yang digunakan adalah algoritma Naive Bayes dengan input berupa jumlah stok, frekuensi barang masuk, dan data kategori barang. Model klasifikasi ini menghasilkan pengelompokan barang ke dalam dua kategori, yaitu laku cepat dan kurang laku, berdasarkan kecepatan habisnya stok dalam periode waktu tertentu. Hasil klasifikasi digunakan sebagai dasar pengambilan keputusan pengadaan barang. Pendekatan ini mampu menyajikan informasi relevan untuk membantu pemilik toko dalam menentukan barang yang perlu segera diisi ulang maupun yang pengadaannya dapat ditunda, sehingga pengelolaan persediaan menjadi lebih efisien dan efektif.

Abstract: This research systematically concentrates on the effect of different dyeing temperatures on the mechanical properties of AISI 1045 steel which has an important role in the field of mechanical engineering. These findings are important for the development of engineering components such as shafts and gears. This study aims to analyze the effect of quenching temperature variations on the hardness, tensile strength, and ductility of AISI 1045 steel experimentally. Heat treatment was carried out through samples up to an austenization temperature of 850°C with a holding duration of 30 minutes, followed by flash dipping (rapid cooling) using water media at temperature variations of 5°C, 15°C, 25°C, and 35°C. Each treatment was carried out five times and statistical analysis was given to obtain representative data. Observation of microstructures using serial light microscopy was carried out including evaluation. The results showed a close relationship between the decrease in coolant temperature and the increase in hardness and tensile strength. However, there is an opposite correlation with material durability. The highest hardness, 58 HRC, and the strongest tensile strength, 1250 MPa, were obtained for samples cooled at 5°C.  Microstructure observations show a more dominant martensite formation at cooler immersion temperatures. The results of this study provide insight into the correlation with the transformation of the mechanical and microarchitectural characteristics of AISI 1045 steel.

Article 19 paragraph (1) of Law Number 5 of 1960 concerning Basic Agrarian Principles "To ensure legal certainty by the government, land registration is carried out throughout the territory of the Republic of Indonesia according to the provisions regulated by government regulations". In fact, there are still many waqf lands that have not been registered with the National Land Agency (BPN), causing weak protection and legal certainty for waqf lands in Indonesia. This research uses normative juridical methods with regulatory and conceptual approaches. The results show that waqf land that is not registered with the national land agency has a weak position before the law, although religiously the waqf land that has been pledged is valid in sharia, but without official administration at the national land agency, the legal protection of waqf land is weak. The legal consequences of waqf land that is not registered with the national land office make the status of the waqf land still the previous property, because land registration is an administrative obligation that must be fulfilled to obtain legal certainty that is recognised in positive law by being registered with the National Land Agency. By not registering with the National Land Agency in accordance with the provisions of the law, the status of waqf land has not been registered as waqf asset land. It is recommended that the National Land Agency continue to socialise the importance of waqf land certificates and cooperate with the Indonesian Waqf Board and the Religious Affairs Office in its registration. It is also suggested that a regulation be made requiring nadhirs to report on waqf practices in the village every six months to record unregistered waqf land.

This study analyzes the effect of fiscal potential, government spending, and human development on regional economic growth in Central Java during the 2020–2023 period. Gross Regional Domestic Product (GRDP), in logarithmic form, is used as the dependent variable, while the independent variables include local fiscal potential (PAD), government spending, and the Human Development Index (HDI). Using panel data regression with a fixed-effect model on 35 districts/cities, the results reveal that HDI has a significant positive impact on GRDP. Meanwhile, fiscal potential and government spending are found to be statistically insignificant. These findings suggest that enhancing human development is a key factor for boosting economic growth in the region.

Penelitian ini merupakan penelitian kualitatif dengan pendekatan fenomenologi melalui teknik pengumpulan data melalui observasi, wawancara, dan analisis dokumentasi. Untuk teknik analisa data, penelitian ini menggunakan reduksi data, penyajian data, dan penarikan kesimpulan. Hasil dari penelitian menunjukkan bahwa ketiga responden, yaitu K.K, N.P, dan M.P, memiliki dinamika berbeda dalam setiap aspek tersebut. Penerimaan diri mereka terbentuk melalui refleksi dan penyesalan atas tindakan masa lalu. Dukungan sosial dari keluarga dan teman di lapas menjadi penting bagi K.K dan M.P, sedangkan N.P mulai lebih realistis terhadap dukungan eksternal. Pada aspek kemandirian, ketiganya berusaha mengelola emosi dan membuat keputusan secara mandiri. Penguasaan lingkungan terlihat dari upaya beradaptasi dan mengendalikan diri dari pengaruh negatif. Pengembangan personal muncul melalui kesadaran untuk memperbaiki diri, dan tujuan hidup mereka difokuskan pada perencanaan masa depan yang lebih baik.

Penelitian ini bertujuan untuk memahami dinamika psikologis ketertarikan mahasiswa yang mengalami fatherless dalam pemilihan profil calon pasangan pacar. Fatherless, dalam konteks ini, merujuk pada kondisi tidak adanya figur ayah secara fisik maupun emosional dalam kehidupan individu. Penelitian ini memiliki fokus pada empat permasalahan utama, yaitu : (1) bagaimana gambaran kriteria calon pasangan pacar dilihat dari aspek kepribadian, fisik, usia, ekonomi, Pendidikan dan figur idola; (2) ekspektasi memiliki pasangan yang mirip dengan ayah atau malah sebaliknya; (3) kekhawatiran dalam memulai hubungan asmara; (4) orientasi seksual. Penelitian ini menggunakan pendekatan kualitatif dengan metode fenomenologi  yang dipilih secara purposive. Teknik pengumpulan data dilakukan melalui wawancara mendalam dan observasi non-partisipatif, kemudian dianalisis dengan pendekatan tematik. Hasil menunjukkan bahwa individu fatherless cenderung memilih pasangan dengan kepribadian mirip ayah namun berbeda secara fisik, lebih tua secara usia, stabil secara ekonomi, setara dalam pendidikan, dan tidak menjadikan ayah sebagai figur idola. Mereka cenderung menolak pasangan yang menyerupai ayah secara emosional. Pengalaman fatherless tidak memicu kekhawatiran dalam memulai hubungan, tetapi dapat memengaruhi orientasi seksual.
