Abstract

Penelitian ini dilakukan untuk melihat peramalan return harga emas dengan menggunakan model GARCH (Generalized Autoregressive Conditional Heteroskedasticity). Hasil analisis return harga emas menunjukkan data tersebut mengalami pengelompokan slot777 volatilitas (volatility clustering) atau kasus heteroskedastisitas. Data yang digunakan merupakan data harga emas periode bulanan yaitu Desember 2007 sampai Desember 2018. Model terbaik yang diperoleh yaitu GARCH (1,1) dengan memperoleh hasil peramalan return harga emas untuk periode Januari 2019 sampai Desember 2019. Kata Kunci : Emas,Peramalan,Volatilitas

Abstract

Increased cost utilization in MSMEs is one of the factors that determine the development of a business, including the challenge of cost distortion due to the use of a traditional Cost of Goods Sold (COGS) system that is subjective and ignores the hidden costs of non-value-added activities. This study aims to analyze cost distortions and identify hidden costs in Cahaya Aluminium MSMEs using the Activity-Based Management (ABM) approach. The research method used is qualitative-descriptive with a single case study design and a descriptive-comparative approach. Primary data was obtained through in-depth interviews validated through triangulation of informal cost data. Data analysis techniques used thematic analysis, starting from data collection, data reduction through Activity-Based Management (ABM) activity coding, and using Activity-Based Cost (ABC) simulations presented in a comparison matrix. The results of the Activity-Based Costing (ABC) simulation showed significant cost distortions in the Kitchen Set (Complex Product) aspect, which experienced undercosting, and the Dish Cabinet (Standard Product), which experienced overcosting. These distortions were triggered by non-value-added activities such as rework and material return waiting time. Based on these results, it can be seen that Activity-Based Management (ABM) through material synchronization and supplier evaluation can improve the accuracy of HPP and operational efficiency for Cahaya Aluminium MSMEs

Abstract

This study is motivated by the high risk of fraud in local government financial management, which remains a significant issue in the public sector. Weak internal control implementation, limited effectiveness of internal audit, and low anti-fraud awareness may create opportunities for financial misconduct. This research aims to analyze the effectiveness of internal control in mitigating fraud risk in local financial management at the Regional Financial Management Agency (BPKD) of Gowa Regency, as well as to examine the role of internal audit and anti-fraud awareness in supporting the internal control system. The study employs a descriptive qualitative approach, with data collected through in-depth interviews, observation, and documentation. Key informants include officials and staff directly involved in financial management and oversight processes. The findings indicate that internal control at BPKD Gowa Regency has been implemented in accordance with existing regulations; however, its effectiveness has not been fully optimized due to limitations in human resources, inconsistencies in procedural implementation, and high workload pressures. Internal audit and anti-fraud awareness play a crucial role in strengthening internal control and reducing fraud risk. This study concludes that strong synergy among internal control, internal audit, and anti-fraud awareness is essential to enhance accountability, transparency, and integrity in local government financial management.
