PT PLN (Persero) Unit Induk Distribusi Jakarta Raya terus melakukan peningkatan pelayanan kepada pelanggan dengan melakukan pemasangan baru sesuai dengan waktu yang ditargetkan. Kecepatan pemasangan adalah salah satu faktor yang mempengaruhi pelayanan dan persepsi pelanggan terhadap perusahaan. PT PLN (Persero) Unit Induk Distribusi Jakarta Raya melayani penyambungan listrik Tegangan Rendah (TR) dan Tegangan Menengah (TM). Berdasarkan identifikasi yang dilakukan ditemukan adanya kendala yang dialami perusahaan sehingga menyebabkan pekerjaan penyambungan menjadi lama. Hal ini ditemukan pada layanan Tegangan Menengah pola 100 hari yang dibutuhkan diatas target 100 hari. Lamanya proses pelayanan mengalami kendala dari sisi eksternal maupun internal perusahaan. Oleh karena itu, perlu adanya analisa mendalam dengan metode tertentu agar perusahaan dapat mencapai target yang telah ditetapkan ditahun berikutnya. Penelitian ini meneliti atribut reliability dan responsivness menggunakan metrik Perfect Order Fullfilment (POF) dan Order Fulfilment Cycle Time (OFCT). Hasil penelitian didapatkan bahwa faktor perizinan dan ketidaksiapan pelanggan menjadi alasan utama keterlambatan pemasangan listrik Tegangan Menengah pola 100 hari.

This paper presents the design and development of a mobile serious game (SG) named MAGNITUDE for training inexperienced disaster volunteers. First, we present interviews with disaster experts to clarify the issues in disaster work and to identify the required criteria for volunteer workers. Second, we explain the survey we did to investigate the subjects' awareness of ethical issues in a disaster situation. The survey involved 64 subjects, classified into two group, i.e. experienced (Ex) and inexperienced (Ix) who were in high school or the early years of university. The results of the survey showed that the Ix group had less awareness of ethical issues than the Ex group. Based on this finding we have been developing MAGNITUDE to harness its training potential. This SG is envisioned as encouraging Ix volunteers-who usually come in the early periods of disaster response work as spontaneous volunteers-to improve their soft-skill of making decisions ethically.

Online learning recently is alternative learning at all levels of education. Online learning in mathematics can be done synchronously or asynchronously, such as using zoom or e-learning. However, online learning is still ineffective in improving students' abilities because of its limitations, especially in high-level skills such as mathematical abilities. This study aims to use online learning with STEM-based media to reveal the mathematical skills of vocational high school students. This research method is a quantitative study with a quasi-experimental design, with two sample groups, namely the experimental group and the control group. The subjects of this study were 120 students of vocational high school. The results showed that STEM-based media could improve the mathematics abilities of vocational high school students seen from the whole student or based on the level of group students. Likewise, positive student responses to online learning using STEMbased media. This response means that students feel the benefits of learning online using STEM-based media.
