Material handling is a term for transportation or transport activities carried out by industrial companies, which involve moving raw materials, semi-finished goods or finished goods from one location to another predetermined location. Apart from that, material handling is also important in quality control, where 3-5% of damaged goods are caused by material handling. The aim of this research is to identify and redesign the layout conditions of concrete production facilities at PT. XYZ. The method of this research is the Activity Relationship Chart (ARC), Activity Relationship Daigram (ARD) and Total Closeness Rating (TCR) methods. In the current layout conditions, the sand warehouse and crushed stone warehouse work stations should be close to the two hoppers, namely the batching plant hopper and the asphalt mixing plant hopper, but in the actual conditions these two work stations are not close to each other. In the new facility layout there are changes and relocation of work stations based on the degree of proximity. Future research is expected to consider the amount of time generated during the material handling process and also consider cost aspects during the process of designing changes to the facility layout.

The micro, small, and medium enterprises (MSMEs) sector plays a vital role in sustaining the national economy, particularly in food security and employment absorption. However, this sector remains highly vulnerable to economic disruptions, including large-scale layoffs in the industrial sector. This study aims to examine the socio-economic impacts of layoffs on the sustainability of traditional fish processing businesses. A descriptive qualitative approach was employed, with data collected through semi-structured interviews with a traditional fish processor who has operated since 1990 in Tanjung Morawa, Deli Serdang, North Sumatra. The findings reveal that layoffs have led to a significant decline in consumer purchasing power, resulting in a drop in daily production volume (from 20 to 5–8 baskets) and increased waste due to unsold inventory. The lack of innovation, absence of adaptive strategies, and minimal external support have further exacerbated the business’s vulnerability. Therefore, policy interventions and capacity-building programs are essential to enhance the resilience of MSMEs amid labor market fluctuations.

Employee transfers are common in companies, but regulations regarding transfer provisions are still very minimal. The absence of specific provisions governing transfers is often misused by employers, resulting in industrial relations disputes, one of which occurred between PT. Amartha Manunggal Prima and Khairunnisa Utami. This study aims to analyze the validity of the transfer process carried out by the company if there are no provisions or legal basis underlying the transfer process. This study uses a normative legal method, by analyzing the conformity between the considerations of the Panel of Judges in Decision Number 24/Pdt.Sus-PHI/PN JMB with laws and regulations, especially Law Number 6 of 2023 concerning the Ratification of the Job Creation. Based on the results of the analysis, a transfer process is one of the company's rights to regulate human resources for the interests and progress of the company and in general transfers are regulated in work agreements, joint work agreements, or company regulations. If the mutation process is not regulated, then the mutation must be based on an agreement between the two parties as mentioned in the Supreme Court Decision Number 567 K/Pdt.Sus-PHI/2016 which stipulates that mutations without the consent of workers can be canceled through the industrial relations court. In addition, mutations must not conflict with existing laws and regulations, especially Article 32 of the Manpower Law which regulates the placement of workers,

The essential oil of lemongrass (Cymbopogon citratus) is a high-value commodity widely used in the food, pharmaceutical, and cosmetic industries due to its bioactive components such as citral. Optimizing its distillation process is necessary to achieve maximum yield with time and energy efficiency. This study aims to determine the hourly yield distribution of essential oil from Lombong-type lemongrass during steam distillation and to analyze its extraction kinetics to identify the optimal distillation duration. Distillation was conducted for four hours with yield recorded each hour, and the data were analyzed using pseudo-first-order and pseudo-second-order kinetic models. The results showed that the highest yield was obtained in the first hour (0.1882%), followed by a sharp decline, with no additional yield observed in the fourth hour. The pseudo-first-order model showed the best fit to the experimental data with a rate constant of k = 0,8012/hour. Meanwhile the pseudo-second-order model did not fit well. These findings indicate that the extraction process is dominated by external diffusion and the rapid release of surface volatile compounds. Therefore, it is recommended that distillation duration be limited to two hours to optimize energy and time efficiency.

The Industrial Design Rights of the Koper Generator have been revoked based on the Decision of the Central Jakarta Commercial Court No. 78/Pdt.Sus-HKI/Desain Industri/2023/PN.Niaga,Jkt.Pst. However, even though the registration of the Koper Generator Industrial Design has been revoked, the rights holder continues to exercise his economic rights, thereby causing real losses to the Plaintiff. Therefore, the Plaintiff filed a lawsuit for infringement of industrial design rights and a claim for compensation. The decision on the lawsuit basically rejected the Plaintiff's lawsuit, on the grounds that the Plaintiff did not have legal standing to file a lawsuit for infringement of industrial design rights and a claim for compensation.Based on the results of the study, it was found that legal protection for related parties or parties interested in industrial design rights is only related to filing a lawsuit for cancellation of industrial design rights, but cannot reach legal protection to file a lawsuit for infringement of industrial design rights and a claim for compensation; Legal considerations of the Panel of Judges of the Commercial Court in case No. 76/Pdt.Sus-Hki/Desain Industri/2023/PN.Niaga.Jkt.Pst, is not appropriate, because it does not consider the fact of bad faith from the Defendants who continue to exercise their industrial design rights, even though their industrial design rights (Genset Koper) have been revoked by a court decision. The fact of direct losses suffered by the Plaintiff is not taken into consideration. This can make the judge's decision based on formalistic or procedural justice.

Through the exploration and analysis of various scientific literature sources from 2019 onwards, this study finds that the two-phase method can systematically provide optimal solutions, especially in complex problems with multiple constraints. Previous research has shown that this method is effective in accelerating the identification of basic feasible solutions and minimizing unnecessary iterations compared to the standard simplex method. Additionally, the two-phase method offers better numerical stability and high reliability in both industrial and educational applications. However, its effectiveness largely depends on the understanding of the algorithm and the ability to design an appropriate mathematical model. The results of this study are expected to contribute theoretically to the development of efficient solution techniques for linear optimization problems.
