Abstract

Human development in Central Java continues to show positive progress, as reflected in the consistent increase of the Human Development Index (HDI) across the province. The HDI serves as a key indicator for assessing the success of initiatives aimed at improving the overall quality of life. It measures how well residents are able to access the benefits of development, including long and healthy lives, education, knowledge, and a decent standard of living. The HDI is influenced by four primary components: life expectancy, expected years of schooling, mean years of schooling, and per capita expenditure. Currently, the Central Bureau of Statistics determines HDI values for each regency and city in Central Java using a specific calculation formula. In this study, we aim to classify these regions into three categories based on their HDI levels: very high, high, and moderate estimate areas. To perform this classification, we applied the K-Nearest Neighbors (KNN) algorithm—an effective, non-parametric method that classifies data points based on the majority class among their nearest neighbors in the feature space. KNN is well-suited for classification tasks involving complex, real-world data, offering both accuracy and interpretability. The classification of the 2024 HDI data using KNN resulted in three distinct groups: Cluster 1 (moderate estimate) includes 18 regions: Cilacap, Banyumas, Purbalingga, Banjarnegara, Kebumen, Wonosobo, Magelang, Wonogiri, Grobogan, Blora, Rembang, Temanggung, Kendal, Batang, Pekalongan, Pemalang, Tegal, and Brebes. Cluster 2 (high estimate) consists of 13 regions: Purworejo, Boyolali, Klaten, Sukoharjo, Karanganyar, Sragen, Pati, Kudus, Jepara, Demak, Semarang Regency, Kota Pekalongan, and Kota Tegal. Cluster 3 (very high estimate) comprises 4 urban areas: Kota Magelang, Kota Surakarta, Kota Salatiga, and Kota Semarang. This classification provides valuable insights into regional development disparities and can support evidence-based planning and policy-making.

Abstract

Kabupaten Sragen mempunyai simpul-simpul transportasi jalan strategis yang menghubungkan kabupaten di Provinsi Jawa Tengah dengan Provinsi Jawa Timur, letaknya di perbatasan kedua propinsi tersebut. Salah satu ruas jalan utama di Kabupaten Sragen yang sering macet adalah Jalan HOS Cokroaminoto, Oleh karena itu Pemerintah Kabupaten Sragen berencana membangun fly over yang melintas di atas persimpangan tersebut. Meskipun demikian, fly over ini juga dapat memberikan dampak negatif antara lain kerusakan lingkungan, debu, berubahnya budaya gotong royong, mengurangi interaksi dan kegiatan sosial yang biasa dilakukan sebelum adanya fly over, sehingga perlu kajian yang lebih mendalam terkait karakteristik lalu lintas jaringan jalan saat ini, kinerja jaringan jalan tersebut saat ini dan kondisi jaringan jalan di atas jika di lokasi tersebut dibangun fly over, serta kondisi 5 tahun yang akan datang. Manfaat yang diharapkan dari penelitian ini antara lain, memberikan tambahan wacana dan referensi dalam mengatasi kemacetan lalu lintas dengan pembangunan fly over dan sebagai bahan acuan Pemerintah Kabupaten Sragen dalam membuat kebijakan dan peraturan daerah terkait pembangunan infrastruktur jalan. Jaringan jalan yang ditinjau adalah Jalan HOS Cokroaminoto, Jalan Sultan Agung, Jalan Diponegoro, Jalan Asem dan Jalan Tentara Pelajar, Karakteristik lalu lintas yang ditinjau adalah volume lalu lintas dan kecepatan arus, parameter kinerja jaringan yang ditinjau berupa kapasitas jalan, derajat kejenuhan dan LOS jalan. Fly over diasumsikan terbangun dalam rentang waktu 5 tahun yang akan datang. Jenis penelitian menggunakan metode deskriptif dan kuantitatif karena peneltian ini bersifat factual berdasarkan data yang ada untuk memecahkan masalah yang terjadi pada ruas jalan Hos Cokroaminoto. Data primer didapat dari dari pengamatan langsung di lapangan selama 2 hari ( Senin dan Sabtu). Tipe jalan yang diteliti adalah jalan perkotaan dengan dua lajur – dua arah (2/2 UD). Metode analisis menggunakan MKJI 1997. Hasil analisa kinerja ruas jalan Hos Cokroaminoto didapatkan nilai derajat kejenuhan (DS) kondisi eksisting sebesar 0,61 total dua arah. Untuk kinerja ruas jalan Hos Cokroaminoto pada 5 tahun mendatang sesuai dengan standart MKJI 1997 didadaptkan nilai derajat kejenuhan (DS) pada kondisi ruas jalan eksisting meningkat menjadi 0,78 hasil tersebut menunjukan nilai derajat kejenuhan (DS) telah melebihi ketetapan yang tertulis dalam MKJI 1997. Sesuai hasil analisa 5 tahun mendatang bahwa di ruas jalan Hos Cokroaminoto memang diperlukan pembangunan fly over sebagai salah satu cara untuk mengatasi permaslahan kemacetan jalan tersebut.

Abstract

This work examines the self-healing properties and corrosion prevention mechanisms of hydrothermally synthesized HAp/PAA (hydroxyapatite/polyacrylic acid) composite coatings on magnesium alloy WE43. The coatings were produced with different PAA concentrations (0.15, 0.3, and 0.5 wt.%) by a hydrothermal method at 140 °C for 3 hours. The composite layers were analyzed using FTIR (fourier transform infrared spectroscopy), SEM (scanning electron microscopy), and EIS (electrochemical impedance spectroscopy) to assess their structural and electrochemical properties, as well as their self-healing capabilities via a scratch–immersion test in Hank’s solution at 37 °C for 48 hours. FTIR analysis confirmed the simultaneous presence of HAp and PAA phases without any chemical reaction, indicating physical contact through hydrogen bonding. The elevation of PAA concentration markedly affected coating morphology, resulting in denser and more uniform structures characterized by spherical HAp crystals at 0.5 wt.% PAA. SEM analysis following scratching and immersion demonstrated that the 0.5 wt.% PAA coating successfully preserved surface integrity and displayed partial restoration of the injured region via the reprecipitation of Ca–P compounds. The EIS findings indicated that the 0.5 wt.% PAA coating maintained the maximum impedance modulus (>10⁴ Ω·cm²) and a steady phase angle after 48 hours of immersion, therefore affirming its exceptional corrosion resistance and self-healing properties. The results demonstrate that an ideal PAA content fosters a dense, ion-responsive hybrid layer that effectively reinstates barrier characteristics following mechanical impairment. The hydrothermally produced 0.5 wt.% HAp/PAA coating offers an efficient self-healing and corrosion-resistant surface for WE43 magnesium alloy, indicating significant potential for use in next-generation biodegradable implant systems.

Abstract

High-entropy alloys are described as equiatomic alloys of more than five elements or materials with five or more element constituents with a high mixing entropy (ΔSmix ≥ 1.5R), where the composition of the element is 5–35%, respectively. One application of HEA (high entropy alloys) materials is in the orthopedic field, where they are developed as biomaterials. Behavior, the correlation between the elemental distribution, and the microstructure of the material were investigated during multiple remelting processes known as Bio-HEAs. The development of Bio-HEAs is exciting in terms of design material, fabrication, and their properties. In this paper, the corrosion behavior and the correlation of the elemental distribution and the microstructure of the material were investigated during the multiple remelting process. The equiatomic CoCrMoMnNb was prepared in vacuum arc melting under an argon atmosphere and melted in a water-cooled copper mold. The total amount of ingot was approximately 25 grams, then flipped and remelted several times, 4, 8, and 12 cycles. The final composition of the alloys was confirmed by EDX (energy dispersive x-ray spectroscopy). The microstructure was investigated with an optical microscope and the SEM (scanning electron microscope). The corrosion parameter occurred in Hank’s solution at 37°C, at a scan rate of 1 mV/s. The CCM-MnNb fabricated with 8 cycles of the remelting process exhibits the lowest corrosion rate (0.0038 mmpy) and donor densities (2.67 × 10¹⁹ cm⁻³), while the charge transfer resistance number is the highest (18250.94 Ω cm⁻²). The outstanding corrosion resistance of the alloys is induced by the presence of the finer dendrites and the chromium oxide (Cr₂O₃) protective layer on the alloy's surface.
