Abstract

The usage of advertising as a medium for marketing products/services is used by various businesses to increase profits. The advertising medium mainly used is billboards, which still use fossil energy as an energy source. The Indonesian government's 2060 Net Zero Emission Program promotes using renewable energy (RE) as an energy source, such as photovoltaic (PV) as electrical energy from solar heat. As with RE, the development of PV still has problems in products and business, but PV is ready to be used as an energy source to reduce electricity bill costs. The business idea of PV installation in the advertising company sector emerged to support the government program Net Zero Emission, making advertising companies "green jobs" and absorbing human resources from vocational schools. Business conceptual design with value chains, business model canvas, and lean canvas expected can provide an overview of business opportunities with EBT for Indonesia that are environmentally friendly and energy independent.

Abstract

This article aims to analyze the debt audit procedures at PT ABC by public accounting firm Namira where this study discusses the procedures and preparation of third party debt audit work papers at PT ABC by KAP Namira. A company will need the help of a third party, namely an auditor to determine the effectiveness of internal controls and the fairness of the financial statements to be examined. With the help of auditors, evidence on the preparation of the company's financial statements can be examined and evaluated in order to improve the ability to manage funding sources for the sustainability of the company's activities and increase the confidence of users of the financial statements produced by the company. In this case the auditor must examine all the components of the company's financial statements, one of which is on the balance sheet there is an account that must be checked by the auditor, namely debt. The debt arises because the company cooperates with third parties to carry out production activities and borrow funds for the sustainability of the company. Debt itself is a liability component that greatly affects every transaction that occurs, because trade payables are company obligations that must be paid and there are nominal misstatements that are very material for the sustainability of a company. To prevent this from the debt balance, it is necessary to conduct an audit as well as an examination. Based on the final project that the author has compiled, it comes from the internship activities that have been carried out and knows the debt audit procedures implemented by KAP NAMIRA including evaluating internal control evaluations, making top schedules and supporting schedules to sending debt confirmations and also doing vouching.

Abstract

High-stress levels can trigger other diseases if emotions are not channeled to reduce the feeling of stress. The stress-releasing activity that is currently trending is keeping animals, especially cats and dogs. Having a pet triggers awareness of the importance of pet care, especially in the context of home visiting services, highlighting the need for increased effectiveness of veterinary services. Determining a short route for veterinarians to visit their patients in a certain area is necessary in planning for pet clinics with home visit services. In the context of home visits by pet clinics, the Traveling Salesman Problem (TSP) is used to determine the most efficient route veterinarians can use when visiting many patients in a certain area by minimizing the total distance traveled to save time. This research uses the Particle Swarm Optimization (PSO) algorithm with 2-opt logic to solve the TSP problem. This TSP optimization was completed by utilizing Google Colab as a machine learning computing medium using Python. The results of optimizing the total distance for the best routes of home visits to pet clinics was 292.81 kilometers. This research can still be developed for more complex routes and have requirements for each route destination, such as visiting time for each patient and distance between destination points. The research is expected to impact the welfare of pets and meet community needs positively.

Abstract

Keamanan sistem informasi merupakan aspek krusial dalam pengembangan perangkat lunak modern,terutama dalam era transformasi digital yang masif. Salah satu metode pengujian keamanan yangberkembang saat ini adalah bug bounty, yakni sistem penghargaan kepada pihak eksternal (eticalhacker) yang berhasil menemukan celah keamanan. Penelitian ini bertujuan untuk menganalisis danmerancang sistem informasi dengan pendekatan keamanan proaktif berbasis temuan bug bounty. Studidilakukan dengan pendekatan kualitatif dan studi kasus pada sistem absensi wajah berbasis web yangtelah mengalami beberapa eksploitasi. Hasilnya menunjukkan bahwa desain sistem yangmempertimbangkan umpan balik dari bug bounty lebih tahan terhadap serangan dan memiliki tingkatrisiko yang lebih rendah
