Abstract

Korosi pada pisau sembelih menjadikan pisau harus diasah kembali agar dapat dipakai. Material bilah pisau yang terbuat dari baja biasanya mengandung inklusi/pengotor. Apabila inklusi itu ada dalam jumlah banyak, maka dapat menyebabkan kerapuhan pada bilah dan menimbulkan potensi korosi. Penelitian dilakukan terhadap pegas daun mobil untuk dibuat pisau sembelih ternak melalui proses tempa taradisional secara berulang. Sebagai acuan pembuatan pisau adalah pisau sembelih merk Z. Dari hasil pengamatan struktur mikro menunjukkan bahwa pada material pegas tampak banyak inklusi berupa flek-flek menyebar rata. Di sekitar inklusi juga tampak potensi korosi akibat oksidasi antara sisa air saat preparasi yang terjebak pada celah di sekitar inklusi dengan oksigen. Setelah kedua pegas tersebut ditempa secara berulang untuk dibentuk menjadi bilah pisau dan diberikan perlakuan panas, maka struktur mikro pisau menjadi lebih padat dan halus. Inklusi dan oksidasi pada material tidak tampak jelas lagi. Kekerasan pada sampel heat treatment dan sampel pisau mencapai ±700HV, mendekati kekerasan pisau merk Z sebagai acuan. Maka disimpulkan bahwa penempaan yang dilakukan berulang-ulang memberikan efek kepadatan struktur mikr

Abstract

The production of rennet enzyme extracted from Mucor pusillus in “onggok” medium the effect of incubation peptone and ammonium nitrate to enzyme production, and the effect of pH and temperature to the activities of rennet were found. The statistical method used is Completed Randomized Design with 3 replicates for each treatment, with the rennet activity in RU/ml enzyme extract. The rennet production was conducted in erlenmeyer (100 ml) that contain 17.5 g “dry onggok” and 50 ml solution of suspension used. The effect of incubation time was detected in three incubation times (4, 7, and 10 day), while effect of peptone and ammonium nitrate to the production of the rennet enzyme was detected in 4 concentrations (0, 1, 2, and 3%) for 7 days of incubation times. The effect of pH to the activity of rennet from the treatment of adding peptone 1% with 7 days incubation time was detected in 5 pH variation (5, 5.5, 6, 6.5 and 7) while the effect of temperature were detected in 5 variations (30, 35, 40, 45, and 50oC). The research results showed that the time of incubation, the addition of peptone and ammonium nitrate affected significantly to enzyme production of rennet Mucor pusillus in “onggok” medium. The highest production of the rennet enzyme products was in the addition of peptone 1% (12.53 RU/ml) with 7 days incubation time. On the treatment of temperature and pH, the optimum activity of rennet Mucor pusillus was in pH 5.5 (40.03 RU/ml) and the activity of rennet Mucor pusillus increased up to temperature of 50oC.

Abstract

The massive development of information technology causes print media to adapt quickly and precisely, one of which is through convergence. The Daily Newspaper Jawa Pos Radar Semeru has converged with social media to maintain its existence in the era of digital disruption. One of the social media shows that are widely appreciated by the public is the flagship program Blak-Blakan on the Radar Semeru TV youtube channel which airs every Wednesday night. In the fourth edition of the Blak-Blakan program with the topic "Batik and Lumajang's Typical Clothes, Whose?” going pretty warm. The Regent's Regulation Number 23 of 2016 concerning Official Clothing for Employees and Officials in the Lumajang Regency Government is considered to have caused polemics and controversies. The polemic of typical Lumajang clothing which describes this regional icon occurs because it has not been specifically regulated by the local government. This study uses the Critical Discourse analysis method from Teun A. van Dijk. The subject of the research is the Blasphemy program which will be broadcast on Wednesday, February 24, 2021. The object is the discourse that is developed through the Blak-Blakan program on Radar Semeru TV. The resource persons in the discussion agreed that the batik and Lumajang's typical clothes used by the State Civil Apparatus every 15th day must be reviewed so that the ideological and philosophical values ​​in them have meaning. Batik and Lumajang's typical clothes used by the State Civil Apparatus and the general public must be unique and reflect the Lumajang community. Batik and street vendors, which will later be agreed upon and ratified through local government regulations, are then registered as HAKI Lumajang so as not to be plagiarized by other parties.

Abstract

CV. Apris Expressindo is a private company engaged in the construction and distributor of U-PVC frames. In its business process activities, CV. Apris Expressindo still does not utilize technology optimally, so that the transfer of information regarding offers, sales, purchases, product stock, suppliers, customers, and financial reports is still done manually. This causes inefficient business processes including: slow fulfillment of customer orders, product pricing errors between divisions, product marketing that is not optimal, financial reports that cannot be seen and controlled by company leaders. Therefore, it is necessary to implement Enterprise Resource Planning (ERP) which aims to overcome these problems. The methodology used in this study was carried out in several stages, namely, data collection: interviews, observation and literacy studies, business process analysis: activity diagrams and use case diagrams, implementation: installation, configuration and module customization, testing: blackbox and UAT (User Acception Test) . The results of this study indicate that the ERP software that has been selected and implemented, namely the Odoo application, can improve and simplify business process activities and can minimize any problems faced today. It is hoped that with this ERP system business operations can be more effective and efficient so that it is expected to provide more financial benefits for CV Apris Expressindo.

Abstract

The contemporary media landscape has undergone profound transformations in the digital age, fundamentally altering how information is produced, disseminated, and consumed across global societies. This study examines the intersection of media imperialism and Islamic educational institutions (pesantren) in Indonesia, focusing on how these traditional institutions resist hegemonic mainstream media narratives regarding radicalism and terrorism. Through qualitative research methodology employing in-depth interviews and content analysis, this research investigates how pesantren develop counter-narratives and alternative media strategies to challenge dominant discourse. The findings reveal that pesantren employ various forms of media resistance, including the establishment of independent media outlets, strategic use of digital platforms, and community-based communication networks. These institutions demonstrate remarkable adaptability in navigating contemporary media challenges while maintaining their cultural identity and educational mission. The study contributes to understanding media imperialism in the Indonesian context and highlights the agency of religious institutions in contesting hegemonic representations. The research concludes that pesantren’s media resistance strategies serve not only as corrective measures against misrepresentation but also as forms of cultural preservation and democratic participation in public discourse.
