Abstract

casing because both processes have important role to derive raw material into the required form, dimensions and characteristics. Cu-Zn 70/30 alloy is raw material which normally used as munition casing however, its formability after deformation and heat treatment is not widely known. Therefore, this research has an objective to study the effect of deformation at warm temperature on cold formability by introducing thermomechanical controlled processed in warm rolling. Warm rolling have been conducted by double pass reversible method on 25% x 2, 30% x 2, and 35% x 2 at temperature 500oC. Evaluation of formability have been done by limited tensile test up to 20% elongation and full tensile test until rupture. The result of this research indicates that the best formability of Cu-Zn 70/30 is obtained on specimen which are deformed by warm rolling at actual degree of deformation 38.7%. Formability testing result for his specimen under designated warm rolling parameter has an elongation 10 % with strain hardening coefficient 0.00228, average normal anisotropy value 0.5452, and plannar anisotropy value ?r 1 is: -0.42. ABSTRAKDeformasi dan perlakuan panas selalu menyertai proses pembuatan selongsong peluru karena kedua proses tersebutlah yang mampu mengatur bahan baku menjadi bentuk dan dimensi yang diinginkan serta sesuai dengan karakteristik yang dikehendaki. Padaun Cu-Zn 70/30 adalah bahan baku yang digunakan untuk pembuatan selongsong peluru, namun mampu bentuk paduan ini akibat deformasi dan perlakuan panas belum banyak diketahui. Oleh karena itu pada penelitian ini bertujuan untuk mempelajari pengaruh deformasi yang dilakukan pada suhu hangat terhadap mampu bentuk dingin dengan metode thermomechanical controlled processed menggunakan teknologi canai hangat. Teknologi canai hangat dilakukan dengan metode double pass reversible sebanyak 25% x 2, 30% x 2, dan 35% x 2 pada suhu 500oC. Pengamatan mampu bentuk dilakukan dengan pengujian tarik hanya sampai perpanjangan 20% serta uji tarik sampai putus. Hasil dari penelitian menunjukkan bahwa sifat mampu bentuk terbaik diperoleh pada benda uji yang dideformasi canai hangat di temperatur 500oC dengan derajat deformasi aktual sebesar 38.7%. Apabila dilihat dari sifat mampu bentuknya maka benda uji yang dideformasi canai hangat pada kondisi parameter penelitian ini memiliki nilai elongasi sebesar 10 % dengan nilai koefisien pengerasan regang yang tinggi sebesar 0.00228, nilai anisotropi normal rata-rata sebesar 0.5452, dan nilai anisotropi planar yaitu ?r 1 sebesar -0.42.

Abstract

Root cause analysis is a method that observes all of the possible causes that make the system or components fail. This research is implemented such a method to investigate the failed front wall tube on the boiler. The purpose of this research is to find out the main cause of failure on the front wall tube to avoid a similar problem in the future.  Considering all aspects that have the potential to be the main cause of failure, therefore, many tests and examinations are done, including visual tests, fractography, metallography, chemical analysis, hardness test, SEM, and EDS analysis.  Examination result on the fracture surface shows two bulges on a tube and some longitudinal cracks spread on bulges outside the surface area. At the same time, the thick scale is also found on the inside surface of these bulges. Moreover, microstructure and hardness changes are also found in this area.  From the analysis of all test result that obtained it is concluded that the main cause of failure is the presence of scales which reduce heat transfer so that local overheating occurred.  Consequently, its tensile strength in this area is decreased, and finally, the tube could not support operational pressure and deformed to make a bulge.      Keywords: Root cause; Failure; Front wall; Tube; Boiler

Abstract

Public health challenges in rural areas of Indonesia are often influenced by low nutrition literacy, suboptimal clean and healthy living behaviors (CHLB), and limited access to healthcare services. This community engagement program aimed to improve nutrition literacy, promote preventive health behaviors, and facilitate early detection of health problems among residents of Gung Pinto Village, Karo Regency. The intervention was conducted on July 24, 2025, at the village hall, involving 30 participants from various age groups. The activities included balanced nutrition and CHLB education through interactive lectures and group discussions, as well as anthropometric measurements, physical examinations, and free medical treatment provided according to medical indications. Results revealed that most participants had a waist circumference above the standard threshold (80%), indicating central obesity, alongside complaints of gastritis/dyspepsia (20%), hypertension (6.7%), acute respiratory infections (3.3%), and mild neuralgia (6.7%). The combination of balanced nutrition and CHLB education, along with health screening and medical services, effectively increased awareness and facilitated the early identification of health issues. These findings underscore the need for integrated, context-specific public health approaches that align with Sustainable Development Goal (SDG) target three on good health and well-being.

Abstract

This article examines the meaning of Islam as portrayed in the Qur’an from Muhammad Asad’s perspective. It explores the interpretation of sacred texts by emphasizing complete surrender to Allah. Asad argues that Islam is not merely a set of rituals or legal rules but a profound spiritual realization that requires total commitment of the heart, mind, and soul to the oneness of God. The study analyzes Qur’anic verses that affirm true salvation rests on sincere belief, confidence in the Day of Judgment, and the performance of virtuous deeds. Furthermore, the article discusses the principle of religious freedom that forbids coercion in matters of faith, allowing individuals to choose their spiritual path without force. Asad’s inclusive approach, which rejects sectarian exclusivity, paves the way for interfaith dialogue and highlights the universal values of Islam that promote human dignity and social justice. The study concludes that the essence of Islam, defined by complete surrender to Allah, is relevant for achieving global harmony and peace. This research offers fresh insights to support mutual understanding and cooperation among diverse religious communities and emphasizes Muhammad Asad’s vital role in renewing Qur’anic interpretation to foster contemporary religious comprehension and spiritual harmony around the world. Overall unity.

Abstract

Pasien kanker stadium lanjut dan pasangannya berisiko tinggi mengalami gangguan psikologis seperti stres, kecemasan, dan depresi yang berdampak pada rendahnya kualitas hidup. Penelitian sebelumnya menunjukkan bahwa hampir 80% pasangan pasien memiliki masalah kesehatan mental dengan penggunaan koping yang terbatas dan bersifat individual. Intervensi dyadic coping terbukti efektif, namun implementasinya sering terkendala oleh keterbatasan akses dan kebutuhan tenaga profesional. Penelitian ini bertujuan mengevaluasi efektivitas self-directed dyadic coping skill training terhadap stres, kecemasan, depresi, kesehatan mental, dan kualitas hidup pasien kanker stadium lanjut. Desain penelitian menggunakan quasi-eksperimen pre–post test dengan total sampel 70 pasangan pasien yang dibagi ke dalam kelompok intervensi dan kontrol. Instrumen meliputi DASS-S, DASS-D, DASS-A, dan kuesioner kualitas hidup. Analisis menggunakan uji paired t-test, independent t-test, dan GEE. Hasil penelitian menunjukkan penurunan signifikan pada stres (mean 2,47; p<0,001), depresi (1,76; p<0,001), dan kecemasan (1,70; p<0,001), serta peningkatan signifikan pada kesehatan mental (5,94; p<0,001). Kualitas hidup kelompok intervensi meningkat secara signifikan dibandingkan kontrol. Temuan ini menunjukkan bahwa self-directed dyadic coping skill training efektif meningkatkan koping pasangan, memperbaiki kesehatan mental, dan meningkatkan kualitas hidup pasien kanker stadium lanjut. Kata Kunci: dyadic coping, kanker, kecemasan, depresi, kualitas hidup.
