Perubahan kompleksitas jalur pada internet sejalan dengan meningkatnya perkembangan internet. Sehingga Network flow optimization menjadi permasalahan utama terkait dengan pemilihan rute terpendek (routing protocol) di balik kompleksitas jalur pada WAN. Algoritma yang digunakan pada routing protocol dirancang untuk memiliki kemampuan pencarian rute terpendek. Dengan perkembangan berbagai algoritma saat ini, apakah algoritma penentuan rute terpendek pada graf seperti A* dapat diterapkan untuk penentuan rute terpendek pada jaringan. Fokus pada penelitian ini yaitu mengetahui dan membandingkan proses komputasi dalam pencarian rute terpendek dengan algoritma Dijkstra dan algoritma A* guna mengurangi beban kerja jaringan. Penelitian dilakukan dengan simulasi pada topologi mesh yang menggunakan fiber link. Berdasarkan hasil simulasi dapat diketahui bahwa algoritma A* memiliki proses komputasi yang lebih sedikit dan jarak yang dihasilkan lebih pendek dibandingkan dengan algoritma Dijkstra. Oleh karena itu, algoritma A* dapat dipertimbangkan sebagai algoritma pada routing protocol.

Supply Chain Management (SCM) aims to maximize the value of the products produced to meet customers' needs and demands. This study aims to conduct an assessment of Supply Chain Management at MS Company and suggested BPMN with adjusted business processes. The Business Process Model and Notation (BPMN) approach is useful for describing complex business process modelling in detail but still easy to understand. Thus, it can minimize errors in implementing business processes. We used the study case approach to conduct this research by studying several journals related to SCM. A discussion was then held to improve the four main processes associated with SCM, and the improvement was written by using BPMN. This study explains that BPMN can be used to give detail and minimize errors so that the modified business process modelling is easy to understand and facilitates communication between business process designers and business process executors. Some MS company improvement in its SCM includes production scheduling, goods procurement, production implementation, and warehouse management. It is suggested that further observation and examination of the improved SCM is needed to prove the new SCM's success in the midst of the covid-19 pandemic.

Background: Nowadays, enterprise computing manages business processes which has grown up rapidly. This situation triggers the production of a massive event log. One type of event log is double timestamp event log. The double timestamp has a start time and complete time of each activity executed in the business process. It also has a close relationship with temporal causal relation. The temporal causal relation is a pattern of event log that occurs from each activity performed in the process.Objective: In this paper, seven types of temporal causal relation between activities were presented as an extended version of relations used in the double timestamp event log. Since the event log was not always executed sequentially, therefore using temporal causal relation, the event log was divided into several small groups to determine the relations of activities and to mine the business process.Methods: In these experiments, the temporal causal relation based on time interval which were presented in Gantt chart also determined whether each case could be classified as sequential or parallel relations. Then to obtain the business process, each temporal causal relation was combined into one business process based on the timestamp of activity in the event log.Results: The experimental results, which were implemented in two real-life event logs, showed that using temporal causal relation and double timestamp event log could discover business process models.Conclusion: Considering the findings, this study concludes that business process models and their sequential and parallel AND, OR, XOR relations can be discovered by using temporal causal relation and double timestamp event log.Keywords:Business Process, Process Discovery, Process Mining, Temporal Causal Relation, Double Timestamp Event Log

Lamora is a cracker and petis industry located in Kauman village, Socah sub-district, Bangkalan district, which has become a pilot MSME. Under the guidance of the Ministry of Industry and Manpower and the Department of Health of Bangkalan Regency, this MSME has had a website (https://kerupukikansocah.com) since 2017. Before the pandemic, Lamora only served orders and purchases directly from individuals or resellers from Bangkalan and its surroundings. However, during the Covid-19 pandemic, sales turnover decreased by more than 60%. This requires serious attention to maintain business continuity. The solution provided is a training and mentoring partnership program to provide MSME actors with the ability to use information technology (IT) as a marketing and sales medium, conduct online marketing on social media, manage online stores in market places and use promotional media design applications for free. The training which lasted for two days has gone well and has achieved the expected goal, namely increasing the understanding of Lamora MSME actors towards online marketing using IT.

This study, conducted at a Private Higher Education Institution (PTS) in East Java Province, aims to compare and empirically test the effectiveness of information systems. The study utilizes the SERVQUAL instrument - tangibles, reliability, responsiveness, assurance, and empathy – measurements in marketing to provide clearer information regarding user/customer satisfaction with information system functions. The hypothesis was rigorously tested using the paired sample t-test and the Wilcoxon rank sum test. The test results show differences in perceived and expected service quality, which are negatively correlated, and there are differences in service quality before and after changes in organizational structure and information systems. Thus, it can be concluded that the changes made by the PTS have not changed the quality of services provided to students. ABSTRAK: Tujuan studi ini adalah untuk membandingkan dan menguji secara empiris efektifitas sistem informasi pada sebuah Perguruan Tinggi Swasta (PTS) di Jawa Timur. Penelitian ini mengadaptasi instrumen SERVQUAL – tangibles, reliability, responsiveness, assurance, and empathy – pengukuran yang dilakukan di bidang pemasaran untuk menyediakan informasi yang lebih jelas mengenai kepuasan pemakai/pelanggan terhadap fungsi sistem informasi. Hipotesis diuji dengan menggunakan uji t sampel berpasangan dan uji peringkat bertada Wilcoxon. Hasil pengujian menunjukkan bahwa ada perbedaan kualitas pelayanan persepsian dan kualitas pelayanan harapan yang berkorelasi negatif dan ada perbedaan kualitas pelayanan pada sebelum dan sesudah perubahan struktur organisasi dan sistem informasi. Dengan demikian dapat disimpulkan bahwa perubahan yang dilakukan oleh PTS tersebut masih belum merubah kualitas pelayanan yang diberikan kepada mahasiswa.
