PT XYZ is a glass manufacturing company with a production efficiency target of 83%. However, the high level of glass loss, especially in the IS Forming process in the C2.4 production line, hindered the achievement of this target. By using the PDCA (Plan, Do, Check, Action) method, this study aims to reduce glass loss caused by the Invert-Revert Center Line Problem. Remedial measures include root cause analysis, resetting technical parameters, and implementing specific solutions such as dummy settings, plunger timing settings, and cooling pressure optimization. From this PDCA approach, there was a significant decrease in glass loss from 173.37 tons to 71.05 tons, or by 59%. This implementation not only improves production efficiency but also provides cost savings. This study shows that the PDCA approach is effective in identifying and solving production problems, so that it can be applied to similar cases in other industrial sectors.

This study aims to investigate the strategies employed by Ellen DeGeneres in using illocutionary acts during conversations on her talk show and examine the perlocutionary effects of her utterances on guests. Using Searle's speech act theory; the analysis focuses on Ellen DeGeneres' interactions with Michelle Obama and Portia de Rossi. This study uses a descriptive qualitative approach and collects the data through library research. The findings reveal that Ellen DeGeneres primarily used assertive illocutionary acts in her talk show, effectively fostering rapport and guest participation. Her assertive strategies include sharing personal experiences and factual statements, guided conversations, and eliciting cognitive and emotional perlocutionary effects, including reflection, agreement, and validation from Michelle and Portia. This study concludes that Ellen DeGeneres' assertive and directive speech acts were key in building rapport and guiding guest interactions, prompting cognitive and emotional responses. English Literature programs should include speech act theory, with workshops and role-play to help students learn and apply it in talk shows or interview simulations. Additionally, media professionals should undergo development programs focused on assertive and directive speech strategies for more dynamic and meaningful interactions.Keywords: Assertive strategies, Illocutionary act, Perlocutionary act, Speech act theory

This study aims to identify and mitigate risks in the purebred chicken egg supply chain in Pesawaran Regency, Lampung Province. The approach used is a combination of the ISO 31000 framework and the House of Risk (HoR) method. The research was conducted on independent breeders and purebred chicken egg distributors, by collecting data through interviews, observations, and questionnaires. Risk identification was carried out using the Content Validity Index (CVI) method, then analyzed using the House of Risk phase 1 to determine the cause of priority risk based on the Aggregate Risk Potential (ARP) value. The eight priority risk causes are determined through the Pareto principle, then classified by risk level. The next stage is risk mitigation using the House of Risk phase 2, by calculating the Effectiveness to Difficulty (ETD-k.) ratio of the proposed mitigation strategy. The results show that the highest priority mitigation strategy is to improve service and fast delivery and provide loyalty programs to repeat customers. This research is expected to be able to contribute to systematic risk management, and can be used as a reference in improving the efficiency and sustainability of the purebred chicken egg supply chain in Pesawaran Regency
