Abstract

The PLN Mobile application was first released on the Google Play Store and App Store in 2016 by the PLN Board of Directors and was relaunched with additional features in 2020. This application was created to realize customer satisfaction from the services provided by PLN. However, in practice there are still complaints from customers and many are written in the comments column on the Google Play Store and App Store platforms. From the many comments, management wants to absorb all aspirations for improvement in increasing customer satisfaction. Management wants to know the statistics on the types of complaints categories reported. Due to the large number of comments, a method is needed to find out the category of disturbance automatically without having to read it one by one. This study offers the Naïve Bayes Classifier algorithm using R programming to provide the required complaint category statistics. Based on the algorithm system that was built, the categorization results obtained are in accordance with the contents of the customer comment messages. With these results, categories of customer comments can be generated automatically, making it easier for management to obtain statistical data related to complaints.

Abstract

This research examines why people enter certification programs. This research examines the supply chain management certification program, the most popular in industry (McCaffery, Backus, & Maxwell, 2020). Extrinsic motivation (Lloyd & Mertens, 2018; Baumann & Bonner, 2016); intrinsic motivation (Quinn et al., 2021; Achtziger & Gollwitzer, 2018; Australian HR Institution, 2017); obtaining a reward or incentive (Australian HR Institution, 2017); and the cost is less than the master's program (Amoruso, 2020; Craig, 2020). AHP is used to rank the 4 criteria's primary aspects. The study sampled experts. Experts are someone with expertise and experience in a subject, system, or sector (Sharma, 2017; Skjong & Wentworth, 2001). This research indicated that incentives were the largest influence in joining a certification program. Extrinsic motivation is second, intrinsic motivation is third, and cost is fourth.

Abstract

This research explores the influence of startups on raising entrepreneurship awareness and enhancing digital literacy in West Java. A mixed-methods approach was employed, combining quantitative surveys with qualitative in-depth interviews and focus group discussions. The study involved 300 respondents with diverse demographic characteristics, allowing for a comprehensive analysis of the startup ecosystem's impact. Quantitative findings revealed that a significant portion of the population in West Java has high levels of entrepreneurship awareness (40%) and digital literacy (35%). Moreover, 60% of respondents reported engagement with startups. Qualitative insights from interviews and focus group discussions emphasized the inspirational role of startups, their contribution to skill development, and the potential for collaboration between startups and educational institutions. The study also found that 75% of respondents perceived a positive influence of startups on entrepreneurship awareness and 70% on digital literacy. These findings underscore the critical role of startups in fostering entrepreneurship awareness and digital literacy in West Java. However, challenges such as resource limitations and the digital divide must be addressed to fully harness the benefits of startups.

Abstract

Titik temu antara keberlanjutan, investasi, dan pembangunan ekonomi telah menjadi titik fokus wacana kontemporer. Studi ini melakukan kajian komprehensif terhadap literatur untuk mengeksplorasi tema-tema utama, tren, dan wawasan dalam domain multidisiplin ini. Melalui analisis bibliometrik, kami mengidentifikasi topik-topik yang menonjol, publikasi-publikasi yang berpengaruh, dan bidang-bidang penelitian yang sedang berkembang. Temuan kami mengungkapkan bahwa "Strategi" adalah tema sentral, menyoroti pendekatan strategis yang digunakan oleh berbagai pemangku kepentingan untuk menavigasi lanskap keberlanjutan dan investasi yang kompleks. "Investor" muncul sebagai aktor penting, menekankan peran penting investor dalam membentuk praktik berkelanjutan dan strategi investasi. "Investasi keberlanjutan" menggarisbawahi penekanan yang semakin meningkat pada pengalokasian modal untuk inisiatif yang menghasilkan keuntungan finansial dan dampak positif terhadap lingkungan dan sosial. "Tujuan Pembangunan Berkelanjutan" ditampilkan secara mencolok, yang mencerminkan keselarasan upaya global dengan tujuan-tujuan ambisius untuk mengatasi tantangan-tantangan sosial dan lingkungan hidup yang mendesak. "Risiko" menggarisbawahi pentingnya penilaian dan manajemen risiko dalam keputusan keberlanjutan dan investasi. Selain itu, kami menemukan istilah-istilah yang lebih jarang digunakan namun memiliki kekhususan seperti "Indeks Keberlanjutan", "Energi Terbarukan", "Investasi yang Bertanggung Jawab", "Kinerja Keberlanjutan", dan "Transisi", yang menandakan bidang-bidang penelitian yang berbeda. Studi ini menyediakan peta jalan bagi para peneliti, praktisi, dan pembuat kebijakan untuk menavigasi medan keberlanjutan, investasi, dan pembangunan ekonomi yang dinamis.
