Seiring dengan meningkatnya kemampuan perangkat seluler, maka kebutuhan akan pulsa juga berkembang pesat. Saat ini reseller hanya memanfaatkan teknologi SMS (Short Message Service) secara konvensional untuk melakukan transaksi. Untuk membantu dalam proses pengiriman pulsa yang lebih efisien, maka dibangunlah menggunakan protokol XMPP. Pada Penelitian ini menggunakan metode perancangan Extreme Programming dengan 4 (empat) tahapan yaitu proses planning, proses design, proses coding dan proses testing. Hasil dari pengujian yang dilakukan dengan menggunakan black box testing  serta kuisioner dari para reseller, aplikasi yang membantu dalam transaksi pulsa, serta meningkatkan efisiensi waktu dalam proses pengiriman pulsa.

In the era of globalization the development of information system technology is very rapidly evolving and very affecting PT. World Innovative Telecommunication engaged in retail, namely mobile phones. Pt. World Innovative Telecommunication still does not have an online marketing and sales system that makes it difficult for consumers to know the products sold. The purpose of this system was to help PT. World Innovative Telecommunication in marketing, selling and increasing sales by using up selling, cross selling and down selling methods and providing convenience for consumers to get information about products sold as well as increase consumer satisfaction by using systems created and covered to unreachable areas.

The Stocks Saving Simulation based on Historical Data Web-based Mesakh Septiadi Simijaya; Aditiya Hermawan

This study aims to simulate the calculation of saving stocks based on historical data for the past 10 years for the period January 2010 - January 2020, because saving simulations based on historical data are still very rare, so a simulation application for saving stock calculations based on historical data is made that can help customers. investors in simulating the calculation of saving stocks so that it can be used as learning to determine how to save the right way that can produce a good return. This application is created using a waterfall model. From the application made, it is expected to know the good return results of the 10 issuers used in this study, and in making basic applications on user requirements obtained through several respondents through online questionnaires and processed with requirement elicitation techniques. With the application of a stock saving calculation simulation application, it is hoped that it can be a lesson for investors in saving stocks and can also be a lesson for potential investors and can also make it easier for investors to do calculations because the calculation process is computerized.

E-Marketing Applications Based On Virtual Reality Using Sostac Planning Method On Sales Property Philip Kristy Wijaya; Aditiya Hermawan
Tech-E Vol 1 No 2 (2018): Tech-E
Publisher : Fakultas Sains dan Teknologi-Universitas Buddhi Dharma

Increased demand for property in Indonesian society, opening up a great opportunity for entrepreneurs to start a business in the property sector. The large number of new entrepreneurs, opening up many different ways of offering attractive products and promos that bring the impact of significant sales decline for those who can not compete. One such problem-solving proposal is to analyze current conditions and create new, powerful goals and strategies to implement. The methods that can serve as guidelines in the analysis and planning of the marketing strategy are SOSTAC (Situation Analysis, Objectives Setting, Strategy, Tactics, Action and Control). Based on the results of SOSTAC analysis and suggestions the way that can be done is to build E-Marketing with media websites that can be easily reached by the public and a marketing tool for marketing executive. On the website created a Virtual Reality feature that can display the form of building to consumers to increase consumer confidence in purchasing units. Based on testing and evaluation by consumers a new marketing strategy plan is worth trying and applied in marketing strategy.

Implementation of XMPP Protocol on Android Pulse Filling Application Aditiya Hermawan; Agus Setiawan
Tech-E Vol 1 No 1 (2017): Tech-E
Publisher : Fakultas Sains dan Teknologi-Universitas Buddhi Dharma

Along with the increasing capabilities of mobile devices, the need for pulses is also growing rapidly. Currently resellers only utilize the technology SMS (Short Message Service) in conventional to conduct transactions. To assist in the more efficient pulse delivery process, it was built using the XMPP protocol. In this study using Extreme Programming design method with 4 (four) stages of process planning, design process, coding process and testing process. The results of testing conducted by using black box testing as well as questionnaires from the resellers, applications that help in the transaction pulse, and improve the efficiency of time in the process of pulse delivery.

Optimization of CNN and Vision Transformer Models in Addressing Long-Tailed Data Imbalance for Satellite Cloud Image Classification Nandivadhano, Revatta Manggala; Aditiya Hermawan; Lidya Lunardi

This study investigates long-tailed satellite cloud image classification by comparing CNN and Vision Transformers (ViT) built upon vision–language foundation models. A large-scale satellite cloud dataset with 11 highly imbalanced classes, including a dominant non-phenomenon category, is used to represent realistic atmospheric variability. The data are split using stratified sampling, standardized to a fixed resolution, and used to fine-tune CLIP-based backbones from RemoteCLIP and GeoRSCLIP through parameter-efficient adaptation. Several loss functions Cross Entropy, Logit Adjustment, Focal, Class-Balanced, and label-distribution–aware variants are evaluated, along with experiments examining majority-class removal and adapter bottleneck adjustments. Initial results show that Logit Adjustment causes majority-class collapse under default settings. After optimization, ViT-based models consistently outperform CNN models, achieving higher accuracy and more balanced macro-level performance. Class-Balanced loss emerges as the most effective objective, offering a strong trade-off between overall accuracy and per-class fairness. Increasing the adapter bottleneck dimension further boosts ViT performance, enabling the best configuration to match or exceed prior benchmarks while improving minority-class recognition. The final optimized model is deployed in a web-based prediction system, demonstrating the practical potential of foundation-model approaches for satellite-driven weather analysis.
