Abstract

This research was conducted to see if there was any herding behavior in stock trading in Indonesia, especially the LQ45 index constituents, which were affected by the effect of the removal of the broker code by the Indonesian Stock Exchange which began on December 6, 2021. The period used in this study was the period before the removal of the broker code, namely June 15, 2020 to December 5, 2021 and the period after the removal of the broker code, namely December 6, 2021 to June 30, 2023. The method used in this study is the approach method by Chang et al. (2000) namely CSAD (Cross Sectional Absolute Standard Deviation) to detect indications of herding behavior. The results of this study indicate that there was no herding behavior on the LQ45 trading stock index either before or after the removal of the broker code. This means that investors act rationally whether the broker code exists or not

Abstract

Penjaminan mutu pada proses produksi pangan merupakan suatu tuntutan yang harus dipenuhi oleh semua produsen. Banyak kendala yang dihadapi bagi industry kecil menengah (IKM) dalam penerapan penjaminan mutu. Salah satu IKM yang mengimplementasikan penjaminan mutu berbasis Hazard Analyziz and Critical Control Point adalah IKM DIA yang memproduksi minuman jahe instan. Jahe instan merupakan produk yang berisiko rendah ( low risk ) dari segi keamanan pangan, tetapi penjaminan mutu harus diterapakn untuk menghasilan produk yang aman dan layak dikonsumsi. Upaya untuk implementasi tersebut adalah melalui penerapan cara-cara pengolahan pangan yang baik (GMP, Good Manufacturing Practices ), dan penerapan HACCP. Implementasi dilakukan secara bertahap melalui pemenuhan 18 runga lingkup GMP. Hasil penilaian GMP menunjukkan bahwa IKM ini terkategori baik dengan beebrapa perbaikan harus dilakukan. Penerapan rencana HACCP sesuai 7 prinsip HACCP telah dilakukan. Hasil audit HACCP menunjukkan perlu adanya perbaikan minor meliputi perbaikan ruang produksi, peningkatan kelengkapan sanitasi pekerja, perbaikan sanitasi ruang produksi, dan perbaikan pelabelan.

Abstract

Pada saat ini permintaan bahan semakin meningkat dengan sifat mekanis yang baik serta ekonomis. Sebagai upaya untuk memenuhi kebutuhan tersebut maka digunakanlah bahan komposit. Komposit adalah gabungan dua atau lebih material yang tercampur secara tidak homogen terdiri dari matriks dan penguat. Berbagai penelitian yang dilakukan umumnya menggunakan satu macam jenis serat sehingga sifat komposit bergantung pada satu serat yang digunakan. Oleh karena itu, penulis menggunakan kombinasi serat daun nanas dan serbuk arang sebagai bahan penguat polymer hybrid composite untuk menghasilkan sifat gabungan antara kedua penguat tersebut. Penelitian yang telah dilakukan memiliki tujuan mengetahui pengaruh variasi penambahan serat daun nanas dan serbuk arang terhadap kekuatan tarik dan ketangguhan impak polymer hybrid composite. Selain itu penelitian bermanfaat memberikan informasi kepada pembaca terkait kekuatan dan ketangguhan polymer hybrid composite dengan penguat serat daun nanas dan serbuk arang. Terdapat tiga variasi perbandingan serat daun nanas dan serbuk arang yaitu 10%:30%, 20%:20%, dan 30%:10% yang digunakan pada uji tarik. Hasil penelitian menunjukkan bahwa kekuatan tarik meningkat seiring dengan bertambahnya fraksi volume serat daun nanas yang diakibatkan oleh pendistribusian beban yang baik serta kemampuan menahan beban tarik yang meningkat. Adapun hasil rata-rata ultimate tensile strength masing-masing 30,15 N/mm2, 41,56 N/mm2, dan 63,59 N/mm2. Sedangkan nilai ketangguhan yang semakin menurun seiring dengan pertambahan serat daun nanas karena ikatan antara serat dengan matriks yang semakin melemah Adapun hasil rata-rata harga impak masing-masing 0,50 J/mm2, 0,44 J/mm2, dan 0,38 J/mm2

Abstract

At the moment the demand for materials is increasing with good mechanical properties as well as economical. As an effort to meet these needs, composite materials are used. A composite is a combination of two or more inhomogeneously mixed materials consisting of a matrix and a reinforcement. Various studies conducted generally use one type of fiber so that the composite properties depend on one fiber used. The research that has been carried out has the aim of determining the effect of variations in the addition of pineapple leaf fiber and charcoal powder on the tensile strength and toughness of the impact of polymer hybrid composites. In addition, useful research provides information to readers regarding the strength and toughness of polymer hybrid composite with pineapple leaf fiber reinforcement and charcoal powder.There were three variations in the ratio of pineapple leaf fiber and charcoal powder, namely 10%:30%, 20%:20%, and 30%:10% used in the tensile test. The results showed that the tensile strength increased along with the increase in the volume fraction of pineapple leaf fiber due to good load distribution and the ability to withstand increased tensile load.The average yield of absorbent energy of polymer hybrid composites is 35.81 J, 35.526 J, and 30.93 J, respectively, while the toughness value decreases along with the increase in pineapple leaf fiber due to the bond between the fibers and the matrix that is getting weaker As for the average yield of impact prices of 0.506 J/mm2, 0.466 J/mm2, and 0.39 J/mm2, respectively Keywords: Composite, Polymer Hybrid Fiber Composite, impact, Matrix.

Abstract

This study aims to analyze the effect of oil price volatility, gold price volatility and exchange rate volatility on the dynamic relationship between Indonesian and United States capital market. The data used in this study are daily closing prices of oil, gold and exchange rates (USD/IDR) as well as Indonesian capital market (JKSE) and United States capital market (DJIA) composite indices during period of January 2005 to October 2020. This study uses DCC-GARCH method to calculate the dynamic correlation between two capital markets and GARCH with the GED parameter to analyze oil volatility, gold volatility and exchange rate volatility on the integration of Indonesian capital market and United States capital market. The results of this study show positive and strong results on the integration of Indonesian and United States capital markets, thus proving that the movements of Indonesian market and American market tend to be strong and mutually influence the two capital markets. Moreover, the oil, gold and exchange rates volatilities have a negative effect on the integration of the Indonesia capital market and the US capital market. This finding implies investors should take oil, gold and exchange rates volatilities in their investment consideration.

Abstract

Objective: Environmental issues are a concern, especially global warming. One of the consequences of global warming is a significant increase in carbon emissions each year. However, investors are trying to understand whether increased carbon also improves companies' financial performance. This study seeks to investigate the influence of carbon productivity on the company’s financial performance (case study of companies listed on the IDX80 index). Research Design & Methods: This research uses a quantitative method with secondary data taken from the company's annual and sustainability reports from 2020 to 2023. The sampling method used is the purposive sampling method. The sample used in this research was 80 companies listed on the IDX80 Index. Panel Data Regression Analysis is used to analyze the data. Findings: The findings of the study indicated carbon productivity has no significant effect on company financial performance, whether measured through ROA or MBR On the other hand, when control variables are added, they have a significant effect on the company's financial performance as measured through ROA. Implications and Recommendations: From these findings, stakeholders, investors and financial managers in the Indonesian capital market can help in making investment decisions, especially regarding the influence of carbon productivity on financial performance and for stakeholders. Contribution & Value Added: This study adds value to the practice of finance that seeks to see that companies that disclose higher carbon emissions will affect the company's financial performance in the context of developing countries, especially Indonesia.
