Turning was carried out at a depth of 0.5 mm, a rotation speed of 1035 rpm, and a cutting speed of 65 mm/min. The results showed that the lowest roughness was in variation 7 (80% corn oil + 10% water + 10% liquid soap) with an initial roughness value of 2.438

The increasing number of devices connected to the network and the rapid growth of data traffic have posed challenges in managing conventional networks. Traditional networks often experience inefficiencies in handling high traffic loads due to static traffic management, leading to congestion in some network paths while others remain underutilized. Software-Defined Networking (SDN) has emerged as an innovative solution by separating the control plane and data plane, enabling more flexible, centralized, and programmable network management. This study evaluates the performance of OpenFlow-based SDN using the ONOS Controller and compares it with conventional home Wi-Fi networks based on the TIPHON standard. The simulation was conducted using Virtual Machines (VMWare) and Mininet, which were connected to the ONOS Controller via the OpenFlow protocol, while the conventional network testing was performed using the Command Prompt. The testing included three data transmission scenarios: 1 host to 1 host, 2 hosts to 1 host, and 2 hosts to 2 hosts simultaneously, with measured parameters including delay and packet loss. The results indicate that in the 1 host to 1 host scenario, both SDN and conventional networks had a delay of less than 150 ms and 0% packet loss. However, in the 2 hosts to 2 hosts scenario, the conventional network experienced an increase in delay and packet loss of up to 17%, whereas SDN remained stable with a delay below 150 ms and 0% packet loss. This confirms SDN's superior efficiency in handling high network traffic through more dynamic traffic distribution. Additionally, this study confirms that SDN's centralized control allows for more adaptive traffic management, reduces congestion, and improves overall network stability. These research demonstrate SDN's efficiency in handling high traffic loads, making it a superior solution for modern network demands.

Social and economic inequality in Indonesia is a multidimensional challenge that is not only reflected in the gap in income and wealth, but also in unequal access to education, health, and economic opportunities. The conventional economic system is considered ineffective in overcoming the problem of fair distribution of wealth, thus widening the gap between the rich and the poor. This article aims to analyze the concept of distributive justice in Islamic economics as a solution to social inequality in Indonesia, by highlighting the synergy of zakat, waqf, sharia financing instruments, and the role of government and society. The method used is a systematic literature review with a qualitative-narrative approach to various related academic works. The results of the study show that the application of the principle of distributive justice in Islamic economics through the optimization of zakat, waqf, and alms, as well as strengthening sharia economic regulations and literacy, can reduce social inequality and improve community welfare. The implementation of an inclusive and sustainable Islamic distribution model can reduce the Gini coefficient and strengthen social solidarity, although it still faces challenges in terms of regulation, literacy, and institutional coordination. The conclusion of the study confirms that Islamic economics offers concrete and holistic solutions to overcome social inequality in Indonesia through the integration of divine values, community participation, and state policies that support distributive justice.

This study aims to analyze price elasticity and income elasticity of products by integrating perspectives from conventional economics and Islamic microeconomics. In conventional economics, price and income elasticity are used to understand consumer demand sensitivity to changes in price and income. Meanwhile, Islamic microeconomics adds an ethical dimension, such as the prohibition of israf (wastefulness) and the importance of balanced consumption. The findings indicate that elasticity analysis is crucial not only for business strategies and economic policies but also must incorporate Islamic economic principles to promote sustainable and ethical consumption. This study suggests that integrating Islamic microeconomic values in elasticity analysis can enrich the understanding of consumer behavior and foster more inclusive economic policies.

Monopoly is a form of market structure characterized by sole control over certain goods or services. In conventional economics, monopoly is often considered as part of market dynamics that can be tolerated under certain conditions, such as natural monopoly. However, from an Islamic microeconomic perspective, monopoly is viewed more critically because it has the potential to cause injustice in the distribution of wealth and market access. This article aims to analyze the concept of monopoly in Islamic economics and examine its implications for market justice. This study uses a descriptive qualitative approach based on literature studies, with sources from classical Islamic literature, the Qur'an, hadith, and contemporary economic theory. The results of the analysis show that Islam forbids monopolistic practices that are detrimental to society, especially in the form of ihtikar or hoarding, and encourages healthy competition and market supervision (hisbah). Thus, the principle of market justice in Islam is not only normative, but has a strong ethical and practical basis to prevent economic domination by a handful of parties.

This study analyzes the dialectic of political interests in the recovery of assets from corruption through the Non-Conviction Based Asset Forfeiture (NCB) mechanism. Using a normative legal approach, the study reveals that NCB is a strategic solution to overcome the limitations of the conventional system, especially in cases where perpetrators flee or have immunity, with the potential to increase asset recovery by up to 40%. Findings indicate that political interests are hindering the enactment of the Asset Forfeiture Bill, despite NCB being mandated by the UNCAC 2003 and proven effective internationally. This study recommends accelerating the legislative process for the enactment of the Asset Forfeiture Bill, which could revolutionize the enforcement of criminal law against corruption in Indonesia

Phishing is an evolving form of cybercrime that targets users' sensitive information through URL manipulation. Conventional detection methods such as blacklists and signature-based approaches have become increasingly inadequate in addressing the dynamic variations of modern phishing attacks. This study evaluates the effectiveness of Recurrent Neural Network (RNN) variants, such Long Short-Term Memory (LSTM), Bidirectional LSTM (Bi-LSTM), and Gated Recurrent Unit (GRU), in detecting phishing threats based on URL data. The methodology involves a Systematic Literature Review (SLR) of scholarly publications from the past ten years, complemented by experimental implementation of the models using a public dataset from Kaggle. Literature findings show that Bi-LSTM consistently achieves the highest accuracy, up to 99%, while GRU stands out for its computational efficiency. Experimental results support these findings, with Bi-LSTM achieving an accuracy of 96.22%, GRU 96.29%, and LSTM 95.43%. Classification metrics indicate that RNN-based models perform very well in detecting benign and defacement URLs, although their performance on phishing URLs remains challenged, particularly in terms of recall. These results confirm that RNNs remain a promising approach for phishing detection systems, especially when integrated into hybrid models with complementary architectures. This study is expected to provide a foundation for developing precise and adaptive AI systems to combat increasingly sophisticated phishing threats.

Islamic economics emerged as an alternative system based on Islamic principles to overcome inequality and social injustice in the conventional economic system. This article aims to examine the role of Islamic economics in achieving social justice through four main pillars: digitization of Islamic finance, empowerment of Sharia-based MSMEs, strengthening Islamic microfinance institutions, and optimizing ZISWAF (zakat, infaq, sadaqah, and waqf). This study uses a qualitative method with a literature review approach using national and international journals published since 2021. The results of the study show that Islamic economics has great potential in building a fair, inclusive, and sustainable economic system if supported by technological innovation, integrative policies, and improving public literacy. This research emphasizes the need for synergy between the government, Islamic financial institutions, business actors, and the community to strengthen the role of the Islamic economy in national development. In addition, it is necessary to strengthen regulations and cross-sector collaboration so that the implementation of the Islamic economy can run optimally in various lines of life. With sustained support, Islamic economics is believed to be able to be a solution to complex modern economic challenges.

This study aims to analyze the extent to which Sharia principles can stabilize the micro, small, and medium enterprises (MSME) market through the framework of Islamic demand and supply theory. In conventional economic systems, price fluctuations and market instability are common challenges for MSMEs. In contrast, Islamic economics offers a value-based approach that emphasizes honesty, justice, the prohibition of exploitation, and the concept of fair pricing (tsaman al-mitsli). This research employs a library research method by reviewing primary and secondary sources, including scholarly journals, classical Islamic economic texts, and recent empirical studies. The findings indicate that implementing Sharia principles fosters market stability through the reinforcement of business ethics, transparent information, and the utilization of Islamic instruments such as zakat, infaq, and profit-sharing-based financing. Furthermore, the concept of barakah (blessing) in transactions strengthens consumer loyalty and business resilience. This study concludes that Sharia principles are not only normative but also practical and strategic in addressing the challenges of market instability in the MSME sector. However, this research is limited to theoretical analysis and lacks empirical field data; therefore, future research employing quantitative or case study approaches is strongly recommended.

The rapid development of digital technology has brought significant changes to the field of education, including movement and dance learning for early childhood.

The production process is a crucial aspect in ink formulation, especially violet spot color inks for gravure printing applications, which cannot be accurately reproduced through conventional process printing systems (CMYK). This research aims to optimize the production parameters of violet gravure inks that often exhibit color instability due to delays in the grinding and adjusting stages. The main focus of this research is to analyze the effect of variations in grinding duration, post-grinding aging time, and the amount of raw material on ink color yield, which is evaluated based on density, CIE Lab*, and ΔE parameters. The methodology used was a descriptive experiment on a laboratory scale. The results showed that the optimal treatment combination of grinding for 90 minutes, aging for 48 hours, and the use of 400 grams of material (P3K2L4) produced the highest density value (1.858) and ΔE (0.572), indicating color stability despite quantity variations. This finding indicates that optimization of grinding and aging time contributes to the improvement of pigment dispersion homogeneity and thermal stability of the resin, even without direct measurement of the transition glass temperature (Tg) value.
