Abstract

Penelitian ini menjelaskan suatu perangkat sistem untuk mendiagnostik malaria dengan mudah, sehingga diharapkan dengan pengaplikasian sistem diagnostik malaria dengan mikroskop tersebut dapat menurunkan tingkat penyakit malaria di dunia terutama Indonesia. Hasil penelitian yang diperoleh yaitu USB Mikroskop Digital dapat memposisikan sel darah tipis malaria dengan tambahan lensa okuler pembesaran 1:100x sehingga dapat menganalisa fase malaria. Kecepatan motor DC dipengaruhi oleh dua faktor yaitu tegangan masukan dari adaptor AC–DC dan pengaturan PWM (Pulse Width Modulation). Untuk kecepatan range tegangan yang aman 7,5 V sampai dengan angka maksimal 12,5 V dan hasil akhir pada tegangan maksimal yang digunakan adalah 12,5 V. Sedangkan untuk pengaturan PWM yang digunakan yaitu 255 PWM. USB Mikroskop Digital memiliki arah pergerakan yaitu pada motor bagian kiri dan kanan bergerak ke arah Kanan – Kiri – Maju – Mundur. Sedangkan pada motor bagian tengah bergerak ke arah Atas dan Bawah.

Abstract

This study evaluates the policy implementation of the face recognition system at Surabaya Gubeng Station as a digital innovation in public service by PT Kereta Api Indonesia (Persero). Using a qualitative approach and the policy evaluation model by William N. Dunn, the study assesses six key indicators: effectiveness, efficiency, adequacy, responsiveness, accuracy, and equity. The findings indicate that the system is effective in accelerating the boarding process, reducing queues, and improving passenger convenience. Efficiency is achieved through reduced staff workload and automated identity verification. However, several challenges remain, including technical disruptions, data input errors, and low digital literacy among users. Personal data protection is also a concern as most users are not fully aware of how their biometric data is managed. Therefore an adaptive governance strategy is needed, involving infrastructure improvement, staff training, public education, and greater transparency in data policy. With these measures, the face recognition system can serve not only as a tool for technical efficiency but also as a form of inclusive and sustainable public service transformation.

Abstract

This study aims to evaluate the quality of Trans Semanggi Suroboyo public transportation services with the support of the GoBis application system as a form of digital-based public service innovation in the city of Surabaya. The research method used is qualitative descriptive with the SERVQUAL (tangible, reliability, responsiveness, assurance, empathy) theoretical approach. The data used includes secondary data from the Surabaya Transportation Office, with the number of GoBis users reaching 327,018 people, GoBis balance users 42,833 people, and saving ticket users 2,095 people. The results of the study show that the tangible and reliability dimensions are relatively good, shown through modern fleet conditions and fairly consistent departure schedules. However, in the dimensions of responsiveness, assurance, and empathy, there are still obstacles related to the speed of response of digital systems, transaction security, and limitations of users' digital literacy. The utilization of GoBis' digital transaction feature is still low compared to the total number of application users. This study concludes that the success of Trans Semanggi Suroboyo is highly dependent on the integration between the quality of physical services and the effectiveness of the digital system. It is necessary to strengthen technological infrastructure, improve data security, and digital education for the public so that the quality of smart transportation in the city of Surabaya can run optimally and sustainably according to the principles of smart mobility.
