Outsourcing is to respond to global economic developments and the speed of technological development so that global competition is very tight. The logical consequence of this condition is the decision by company leaders or management to hand over or outsource some of the company's processes to other parties. The aim of this research is the implementation of Law Number 11 of 2020 concerning Job Creation in relation to providing protection for outsourcing workers. This type of research is qualitative, with a normative legal research approach. The results of the discussion obtained the answer that legal protection for outsourced workers is viewed from the principle of legal certainty in Law Number 13 of 2003 and Law Number 11 of 2020 on Job Creation concerning Employment which can be seen in two forms, namely legal certainty in preventive protection and legal certainty in repressive protection. Legal certainty in the context of preventive protection covers several aspects, including clarity regarding employment relations, time-limited work agreements (PKWT), social security, wage levels and wage compensation. In the context of outsourcing, there are no longer any restrictions on the types of work that can be outsourced. For this reason, regulations are needed that provide further detail regarding legal certainty in preventive and repressive protection, to ensure more comprehensive protection.

Madura bull are one of the local bulls in Indonesia whose semen is used for artificial insemination. This study aims to evaluate the quality of semen and the repeatability value of semen from Madura bulls at the Lembang Artificial Insemination Center. A total of 1,402 semen collection data from three Madura bulls from 2014-2020 were used for analysis. The data was analyzed descriptively to evaluate semen quality consisting of semen volume, sperm motility and sperm concentration. Repeatability value was estimated using analysis of variance and intra-class correlation. The results showed that the average volume, motility, and concentration were 5.32 ± 1.50 ml; 68.10±7.07 %; and 1,044.27 ± 277.63 million/ml. The semen volume repeatability value was high, motility was low, and concentration was medium.

To ensure the quality of mass-produced products, non-destructive material testing (NDT) is required with a method that has high testing speed and accuracy. Products that have undergone heat treatment such as automotive components to obtain a specific hardness value need to be tested to ensure the desired quality. Some parameters such as coercivity and permeability of the ferromagnetic materials, can be used to characterize the shape of the hysteresis curve. The hysteresis curve geometry is related to mechanical hardness, hot working record, and the presence of residual stresses. This paper will present how the coercivity value measurement can be done using the Barkhausen effect, as well as a study of the correlation between the coercivity value and the hardness of a ferromagnetic material using the regression analysis method. Indentation testing has also been done to verify different approaches to obtain hardness value by Barkhausen noise analysis. The research shows that this technique was sufficiently accurate with superior rapid testing and no indentation mark.

The Covid-19 incident, many companies in Indonesia have difficulty in carrying out their activities. One of the impacts is the cessation of company activities and laying off employees. This means that many workers or laborers lose their jobs due to situations beyond the control of the company, such as this pandemic. Force majeure is an event or incident beyond human control that can affect business continuity. The purpose of this study is to analyze how legal protection for workers/laborers due to Termination of Employment on the grounds of Covid 19 as force majeure can be applied in the Karawang industrial area. This study uses the approach method. Legislation, where researchers analyze and interpret various laws that are relevant to the topic and object being studied. The results of the study show that the implementation of Termination of Employment by force majeure cannot be carried out arbitrarily, companies must maintain and make maximum efforts not to carry out Termination of Employment before finally deciding to take the route of Termination of Employment for workers/laborers. This is used as the meaning and form of legal protection carried out by the company towards employees.Keywords: Labor; COVID-19; Legal Protection; Work termination

This study aimed to determine the effect of age on bulls productivity and fresh semen characteristics of Simmental bull in Indonesia. A total of 1071 data of semen collection and production from four age groups (two years old (yo), four yo, 10 yo with high semen rejection (10 HR), and 10 yo with low semen rejection (10 LR) were used in this study to evaluate the productivity and characteristics of fresh semen. The results showed that the pre-freezing and post-freezing semen rejection rate of 10 HR group was higher (P0.05) than the other groups. The four yo group had the percentage of second semen ejaculation each collection was higher (P0.05) than the other groups. Furthermore, semen volume, sperm concentration, and total sperm concentration significantly increased (P0.05) until four yo and then decreased (P0.05) in 10 yo groups. The 10 HR group had the volume and total sperm concentration significantly different (P0.05) with a group of 10 LR. Total sperm motility, individual motility, and mass movement were lower (P0.05) in 10 HR than the other groups. In conclusion, age differences of bulls can affect the productivity and characteristics of fresh semen.

Red mud is a by-product of industry that has high levels of iron, aluminum, and silicon oxides. It can be used to strengthen aluminum matrix composites. However, its uneven phase distribution and the tendency of particles to clump limit its effectiveness. This study looks at a coal gangue surface barrier to improve red mud reduction and separate iron phases more effectively. We tested three methods: untreated red mud, magnetic pre-treatment, and barrier-assisted reduction. The results show that traditional reduction requires temperatures above 800 °C because of contamination. In contrast, the barrier-assisted method achieves effective reduction at around 550 °C. This finding aligns with thermodynamic predictions. XRF and XRD analyses confirm better separation. Magnetite is the main component in the magnetic fraction, while Al–Si-rich phases, such as corundum and quartz, are more concentrated in the non-magnetic fraction. Notably, the barrier-assisted reduction approach achieved an iron recovery of 99.04%, markedly higher than the 71.37% reported in earlier studies. As a result, the coal gangue barrier enhances its potential as reinforcement in lightweight automobile composites by improving reduction efficiency and producing cleaner Al–Si-rich material.
