Abstract

Forensic voice comparison (FVC) is gaining global recognition as a scientific method for speaker identification in legal proceedings. In Indonesia, however, the application of FVC remains underdeveloped, despite increasing reliance on digital and audio based evidence in criminal cases. This study presents a legally and methodologically robust framework for implementing FVC within the Indonesian judicial context. The research integrates Indonesian legal standards (KUHAP Articles 183–184, UU ITE) with international forensic protocols, including ISO/IEC 27037 for digital evidence handling. A combination of acoustic features MFCCs, F0, formants, and VTLN was extracted from disputed and reference voice samples. Likelihood ratios (LRs) were calculated using Gaussian Mixture Models, with score calibration via logistic regression. Results showed mean log LR values of 2.1 for genuine trials and –1.8 for impostor trials, with an ROC AUC of 0.91. Visual tools, including Tippett plots and ROC curves, were used to interpret and communicate evidence reliability. The findings confirm that calibrated, probabilistic FVC methods are feasible and legally admissible in Indonesia. However, challenges remain in handling low quality recordings, maintaining chain of custody, and bridging communication gaps between scientific experts and legal practitioners. The study recommends structured training, standardized protocols, and the use of visual aids to enhance evidentiary transparency. This framework lays the foundation for a scalable, court ready FVC system aligned with national law and global best practices. It supports interdisciplinary cooperation aimed at strengthening Indonesia’s forensic infrastructure.

Abstract

Berbagai cara promosi dilakukan oleh para penjual agar produk jualannya dibeli oleh pelanggan, baik secara offline atau online. Banyak pembeli yang tertarik untuk membeli produk hanya dengan melihat foto-foto produk atau video yang lewat di beranda social media, e-commerce, flyer, dan lain-lain, sehingga cara membuat foto yang menarik atau video produk yang menggelitik ini dibutuhkan ilmu tentang photography, karena mungkin masih banyak para penjual membuat foto produk ala kadarnya, padahal tampilan foto atau video yang menarik bisa membuat pelanggan atau calon pembeli untuk memutuskan melakukan pembelian. Berdasarkan latar belakang tersebut, dalam upaya meningkatkan kualitas foto atau produk yang akan digunakan sebagai promosi demi meningkatkan penjualan secara offline atau online, Dinas Perindustrian, Perdagangan, Koperasi, Usaha Kecil dan Menengah (PPKUKM) DKI Jakarta berkolaborasi dengan Institut Ilmu Sosial dan Manajemen STIAMI mengadakan pendampingan kepada pelaku UKM binaan DKI Jakarta atau Jakpreneur dalam berbagai bidang (disiplin ilmu), dan salah satunya bidang   Foto dan Video Produk. Penelitian ini menggunakan metode kualitatif yang hasil penelitian menunjukan bahwa foto dan video produk  dapat meningkatkan pengunjung di media sosial, terutama penjualan online, dan disarankan foto produk dibuat lebih besar.

Digitalisation of public service quality focuses on providing services that are more efficient effective and more transparent. Digitalisation of public service quality is implemented in the transformation of technology from analogue to digital processes. This topic is interesting to study because it is motivated by the results of Cordella &; Lindgren et al, 2019; Ranerup & Henriksen, 2019; Wihlborg, Wirtz et al, 2019), the conclusion of their research is "Digitalisation of public service quality changes public services by promising more efficient, more effective, and more transparent". The phenomena that occur in public services in Indonesia include service discrimination, the absence of certainty of time and cost and the low level of public satisfaction with public services, raising the question of what concrete steps the government has taken to overcome these public service problems. One of these concrete steps is the implementation of digitisation using internet-based information technology in the provision of various DKI Jakarta government services to the community. The writing of the article was carried out with a quantitative descriptive analysis method, data sources in the form of primary data and secondary data. Primary data collection by distributing questionnaires through google form. The results of primary data collection were processed and analysed using Ms Excell. The research location was conducted in the city of Jakarta as a smart city or smart city, involving 325 respondents who live in Jakarta with a minimum education requirement of high school equivalent, minimum age 21 years maximum 60 years, from various professional backgrounds including TNI / Polri, state civil apparatus, private sector, educators, journalists and entrepreneurs. The conclusion is that by implementing digitalisation of public service quality, it has succeeded in improving the quality of services provided by the Jakarta government to the community. The recommended advice related to implementing digitalisation of public service quality is to increase innovation and increase community support for digitalisation programs through socialisation and relevant, reliable and continuous training.
