Analisis Aktivitas Pemeliharaan Preventif Berdasarkan Reliability Growth Pada Dryer Kiln
No full textPenelitian ini bertujuan untuk mengevaluasi pengaruh implementasi predictive maintenance terhadap pertumbuhan keandalan sistem Dryer Kiln serta mengoptimalkan interval preventive maintenance yang efisien, ekonomis, dan tetap menjamin keberlanjutan operasi pada fasilitas pengolahan nikel PT Vale Indonesia Tbk. Analisis keandalan dilakukan pada enam komponen utama dryer, yaitu Pinion & Bull Gear, Main Drive, Burner System, Internal, Apron Feeder, dan Shell & Drum, menggunakan parameter MTBF, MTTR, dan physical availability berdasarkan data operasi periode 2020–2024. Model Crow-AMSAA digunakan untuk menilai reliability growth masing-masing komponen dan sistem, sedangkan konfigurasi keandalan ditentukan melalui evaluasi 406 kombinasi seri–paralel dengan pemilihan berdasarkan Root Mean Square Error (RMSE). Hasil penelitian menunjukkan bahwa implementasi predictive maintenance berdampak positif terhadap peningkatan pertumbuhan keandalan. Profil keandalan dengan preventive maintenance memperlihatkan peningkatan stabilitas dan penurunan frekuensi kegagalan dibandingkan tanpa pemeliharaan. Optimisasi interval preventive maintenance terhadap 729 kombinasi waktu menunjukkan bahwa interval minimum memberikan performa keandalan terbaik untuk lima komponen utama, sementara Shell & Drum dapat diperpanjang hingga 300 hari tanpa menurunkan Overall Equipment Effectiveness (OEE) atau meningkatkan biaya Cost per Unit Time (CPUT) secara signifikan. Hasil ini menegaskan bahwa optimisasi interval pemeliharaan mampu mencapai keseimbangan antara biaya pemeliharaan yang minimal dan tingkat keandalan sistem yang tinggi. Hasil penelitian ini merekomendasikan peningkatan sistem predictive maintenance berbasis monitoring kondisi, evaluasi berkala interval pemeliharaan, strategi perawatan khusus untuk komponen termal kritis pada dryer, serta integrasi model keandalan ke dalam sistem digital twin untuk mendukung pengambilan keputusan pemeliharaan berbasis data
Integration of DEMATEL and ANP methods to evaluate digital transformation maturity model in Indonesian higher education institutions
No full textDigital transformation has become a necessity for higher education, but the existing maturity models are often irrelevant to the unique context of universities in Indonesia. This study aims to develop a comprehensive maturity assessment model using an integrated approach of Decision Making Trial and Evaluation Laboratory (DEMATEL) and Analytic Network Process (ANP) to determine the priority weight of criteria based on their interdependencies. The DEMATEL method was used to map cause-and-effect relationships based on a framework of seven dimensions and 21 criteria validated by, the results of which became input for ANP to calculate priority weights. The study results show that ‘Awareness and Adaptability’ is the most dominant trigger (cause) factor, while ‘Governance’ is the most influenced (recipient) factor, indicating that it is the result of the maturity of other factors. The dimensions of ‘Human Resource Development’ and ‘Security and Privacy’ emerged as the highest priorities with a weight of 15.93% each. This study produced a contextual model that concludes that an effective digital transformation strategy for higher education in Indonesia must be gradual, prioritizing the improvement of human resource capacity and cybersecurity strengthening as a systemic foundation before large-scale technology investment. This model provides university leaders with strategic guidance in decision-making and resource allocation

Harmonic ionospheric oscillation by the 2010 eruption of the Merapi volcano, Indonesia, and the relevance of its amplitude to the mass eruption rate
No full textUsing continuous data from ground-based Global Satellite Navigation System (GNSS) receivers in Java and Sumatra, Indonesia, we studied the response of ionospheric total ionospheric electron content (TEC) to the 2010 Nov.5 eruption of the Merapi volcano in central Java. We then compared the results with the case of the 2014 Feb.13 eruption of the Kelud volcano, eastern Java. The TEC showed a quasi-periodic oscillation of a frequency ~4 mHz with average amplitudes of 0.9 and 1.8% relative to background values lasting for ~20 and ~ 120 min for the Merapi and Kelud eruptions, respectively. By comparing the two cases, together with the 2015 April eruption of the Calbuco volcano, Chile, we found the relative TEC oscillation amplitude may scale with the mass eruption rate. This suggests that the product of such TEC oscillation amplitude and the duration provides a new measure for the total volume of the volcanic deposits

No full textمستخلص البحث
البحث يأتي من فضول الباحثين ، حول خصوصيات وعموميات الوليونغو نشر الدين في جاوة. كما تخلى الوالسونغ عن جميع أنواع العلوم والتاريخ والثقافة ليتعلم الجميع في المستقبل. ومن خلال تفرد قبر سنن مولانا مالك إبراهيم ، يهتم الكاتب باكتشاف الرسالة الضمنية في علامة مميزة. ليس ذلك فقط ، نادرًا ما توجد علامة مميزة في مكان آخر لأنها مصنوعة من الرخام ، ثم نحتت خطًا جميلًا ومثيرًا للاهتمام. يستخدم هذا البحث أساليب البحث الميداني مباشرة من خلال المقابلات والتوثيق وإطلاق النار في موقع القبر سنن مولانا مالك إبراهيم. الغرض من هذا البحث هو معرفة الكتابات المختلفة المنحوتة في قبر سنان مولانا مالك إبراهيم ومعرفة العنصر الفلسفي في صنع العلامة. بحيث يمكن استخدام نتائج هذه الدراسة للحصول على مواد بحثية أكثر عمقًا ويمكن استخدام علم فن الخط لتوفير دروس للطلاب الذين يرغبون في تعلم فن الخط.
يضع المؤلف حدود المشكلة في هذه الدراسة التي فحصت في الأصل الآثار الكاملة لأغنية الوصي ، وهو بحث في مقبرة مولانا إبراهيم إبراهيم. لأن سنان مولانا مالك إبراهيم هو أقدم الوصي بين الوالونجو الآخر. وعلى قبر قبر السنان مولانا إبراهيم إبراهيم هناك نحت رخامي على شكل فن الخط ، والذي نادراً ما يوجد في مقابر الأوصياء الأخرى. تستخدم معظم مقابر والسونغو الأخرى منحوتات خشب الساج كزينة من قبورهم.
نحت قبر ضريح سونان مولانا مالك إبراهيم من ولاية غوجارات ، وهناك رأي آخر أن النقش يأتي من شامبا. الذي أحضره التلاميذ سنن مولانا مالك إبراهيم. يشبه نموذج المقبرة نموذج مالك مالك آل سلطان. شكل القبر يصور القارب رأسا على عقب لا يمكن العثور عليه في مقابر اندونيسيا. هذا يثبت أن نحت الحجر يأتي من الخارج.
نحتت شاهدة القبور بنقوش من آيات من القرآن تحتوي على رسائل ودروس للحياة. لسلو إبقاء إيمانهم. لأنه بعد الموت سيعودون إلى منشئهم ويحاسبون على أعمالهم في حياتهم. إن شاهد القبر محفور بمعلومات حول من دفن هناك ، وعندما يموت الشخص ، وما هي درجة وجوده ، والرسالة الضمنية الممنوحة للعيش.

And on the tombstone of Sunan Maulana Malik Ibrahim's tomb there is a marble carving in the form of calligraphy art, which is rarely found in the tombs of other saints. Most other walisongo tombs use teak wood carvings as decoration for their tombs.
The carving of the tombstone of Sunan Maulana Malik Ibrahim's tomb comes from Gujarat, there is another opinion that the carving comes from Champa. Which was brought by the students of Sunan Maulana Malik Ibrahim. The model of the shape of the tomb is the same as the shape of the tomb of Sultan Malik Al-saleh. The shape of the overturned boat shoot tomb cannot be found in Indonesian cemeteries. This proves that the stone carvings come from abroad.

Because after death they will return to their creator and be responsible for their actions in life. The tombstone is engraved with information on who was buried there, when the person died, what title he has and the implied message given to people who are still alive.
ABSTRAK
Penelitian berasal dari rasa penasaran peneliti, tentang seluk-seluk beluk para walisongo menyebarkan agama di jawa. dan para walisongo juga meninggalkan berbagai macam ilmu, sejarah, dan kebudayaan untuk dipelajari semua orang di masa yang akan datang. Dan dari keunikan batu nisan makam Sunan Maulana Malik Ibrahim, penulis tertarik untuk mencari apa isi pesan tersirat yang ada di batu nisan tersebut. tak hanya itu, batu nisan itu jarang ditemui di tempat lain karena dibuat dari batu marmer, kemudian diukir kaligrafi yang indah dan menarik. penelitian ini menggunakan metode penelitian lapangan secara langsung melalui wawancara, dokumentasi dan pengambilan gambar di situs makam sunan maulana malik ibrahim. tujuan dari penelitian ini untuk mengetahui berbagai macam tulisan yang dipahat di makam sunan maulana malik ibrahim dan untuk mengetahui unsur filosofis dari pembuatan batu nisan tersebut. agar hasil penelitian ini dapat dipergunakan untuk bahan penelitian selanjunya yang lebih mendalam dan ilmu dari seni kaligrafi dapat digunakan untuk memberikan pelajaran bagi mahasiswa yang ingin mempelajari seni kaligrafi.
penulis membuat batasan masalah untuk penelitian ini yang pada mulanya meneliti seluruh peninggalan para wali songo, menjadi penelitian di makam Maulana Malik Ibrahim. karena Sunan Maulana Malik Ibrahim adalah wali tertua di antara para walisongo lain. Dan di batu nisan makam Sunan Maulana Malik Ibrahim terdapat ukiran batu marmer berbentuk seni kaligrafi, yang jarang ditemui di makam-makam wali yang lain. Kebanyakan makam walisongo lain menggunakan ukiran kayu jati sebagai hiasan dari makam mereka.
Ukiran batu nisan makam Sunan Maulana Malik Ibrahim berasal dari Gujarat, ada pendapat lain bahwa ukiran tersebut berasal dari Champa. Yang dibawa oleh para murid Sunan Maulana Malik Ibrahim. Model bentuk makamnya sama dengan bentuk makam Sultan Malik Al-saleh. Bentuk makam tunas perahu terbalik tidak dapat ditemui di makam-makam Indonesia. Hal ini membuktikan bahwa ukiran batu tersebut berasal dari luar negeri.
Batu nisan itu dipahat dengan ukiran ayat-ayat Al-qur’an yang mengandung pesan dan pelajaran bagi orang yang masih hidup. Untuk salelu memelihara iman mereka. Karena setelah mati mereka akan kembali ke penciptanya dan mempertanggung jawabkan perbuatan mereka di masa hidup. Batu nisan tersebut dipahat informasi siapa yang dikubur di sana, kapan orang tersebut meninggal, apa gelar yang dimilikinya dan pesan tersirat yang diberikan untuk orang yang masih hidup
TRANSFORMATION OF ECONOMIC THEOLOGY FOR COMMUNITY EMPOWERMENT: A Case Study on Pesantren-Based Bank Wakaf Mikro
No full textThis article studies the transformation of economic theology indicated by the present of financial service access provided by the government to the lower-class society, particularly those living around pesantren. They so far find difficulty in accessing financial service as they are faced with the requirement of collateral and high interest rate. Responding to such condition, Indonesian government develops micro-sharia financial institution called pesantren-based Bank Wakaf Mikro (BWM). This institution has developed and reached many lower-class people with affordable loan scheme in the last five years. Uniquely, this institution not only provides financial loan but also contains theological and Islamic economic education dimensions through weekly halaqah (study circle) activity. This halaqah becomes a place where the customers of BWM attend pengajian (communal Quran study) held by BWM and perform dhikr (remembering Allah by saying laa ilaha illaallah). Through observation and interview, the author studied the vision of pesantren-based BWM founder, strategy and activities conducted and economic theological transformation in the frame of lower-class community empowerment. This research contributes to encouraging the solidarity-based economic activities in the context of Islamic economic theology
