Applying the dormitory system for thousands of santri (student of Islamic boarding school in Indonesia), Quranic pesantren (Islamic boarding school) has been considered as one of the main culprits in the spread of the coronavirus disease 2019 (COVID-19). Such assumption is created solely from the applicable health protocols and protective measures to avoid COVID-19 transmission in pesantren. As a matter of fact, pesantrens are known to have applied a distinctive way of coping with COVID-19. This study aims to elucidate the theology of health of Quranic pesantren in the face of COVID-19. Research data were generated through observational method on three Quranic pesantrens in Yogyakarta, interviews with caregivers, the COVID-19 task force of the pesantren, santri and documentation related to the handling of COVID-19 in the three pesantrens. The results showed that the Quranic pesantren as a subculture has a distinctive way of dealing with COVID-19 pandemic by integrating modified health protocols in accordance with the actual conditions of the pesantren and by applying rituals of Islamic spirituality by reciting verses of the Qur’an, salawat (prayers for the Prophet), prayers and hizib (prayer for salvation and rejecting calamities). Three pesantrens chose these methods by drawing on the belief that COVID-19 is God’s creature and, thus, it only works on God’s orders and will stop if God wills. In line with this, this study suggests a method for handling COVID-19 by not only emphasising the health protocols and medical procedures but also taking into account the importance of local wisdom.Contribution statement: This article contributes to the strategy of COVID-19 handling by combining the health protocols of COVID-19 and the applicable local wisdom, such as religious ritual as practiced by numerous pesantren in Indonesia.

Relations that exist between the Qur'an and local traditions of society cause variations in the exegesis writing tradition. One of the reasons why there are variations is to make it easier for the public to understand the contents of the Qur'an. This is as happened in Javanese society, with the tradition of using the pégon script in exegesis writing. The pégon script is generally used by the Javanese as a medium for scientific transmission. Pegon script and pesantren is like the two sides of the coin that cannot be mutually separated. History shows, pégon becomes an important part in pesantren world civilization because the learning and intellectual works of pesantren are very dominant with the pégon tradition. This study uses a phenomenological approach as an effort to explain the phenomenon of the writing of the pégon in pesantren exegesis. This study concludes that the use of the pégon script in the writing of pesantren works such as Tafsir Al-Ibrīz fī Ma'ānī al-Qur'ān al-`Azīz by KH Bisri Mustafa, Al-Iklīl fī Ma`ānī al-Tanzīl by KH Misbah Mustafa Mustafa and Tafsir Al-Maḥallī by KH Mudjab Mahalli is not just a communication tool to convey the writer's message to the reader, however, more than that, it has educational functions in many ways. This can be seen in the use of the pégon script with the Gandul translation model. The use of the meaning of gandhul in the exegesis using pégon becomes a kind of Arabic-Javanese dictionary because the translation process uses the word for word model, so this makes it easier for Javanese people to understand the contents of the Qur'an. Besides that, the use of the pégon script in Javanese pesantren exegesis writing also functions as a medium for learning nahwu or Arabic grammatical system and also as a cultural identity of Javanese society.

An energy-saving device (ESD) is used to obtain energy lost and convert additional energy to a propulsive coefficient. This research uses PBCF as an energy-saving device that is attached to an MP687 propeller and a Japanese bulk carrier a hull. Method for solving this research using the open water test and self propulsion method based on computational fluid dynamic (CFD). Added propulsive coefficient obtained from PBCF conventional can reach up to +1.52 %. PBCF with duct make smaller added for propulsive coefficient caused by duct splitting fluid flow from the propeller. PBCF with duct can increase propulsive coefficient up to +0.48 %. PBCF can eliminate a strong hub vortex at propeller MP687 and its ba e good choice for the increased propulsive coefficient of the ship
