Water is an essential resource for every household. Typically, household water distribution systems rely on PVC pipes and faucets. Despite this, water leakage remains a frequent issue, occurring in both pipes and taps. This study aims to design an Arduino-based automatic faucet control system capable of detecting leaks in water pipes, with the goal of conserving water and improving usage efficiency. The system employs a pressure sensor to monitor water pressure within the pipe, an ultrasonic sensor to detect user presence at the tap, and a solenoid valve to automatically shut off the water supply in the event of a leak. Testing and design outcomes indicate that the system functions effectively. The solenoid valve successfully closes the water flow automatically when a leak is detected. However, the current system lacks a notification feature to alert users when a leak occurs. Future developments should consider integrating a notification mechanism to inform users promptly about any detected leaks.

Fermentation is one of the traditional food processing techniques that not only functions as a preservation method, but also plays a role in improving the nutritional quality and safety of food. One example of a typical Indonesian fermented food that has survived from generation to generation is naniura, a traditional dish of the Batak Toba people made from carp (Cyprinus carpio) which is processed without a cooking process. The fermentation process in naniura is carried out spontaneously by soaking in a solution of citrus (Citrus Sp.) and a mixture of local spices, thus creating an acidic environment that supports the growth of fermentative microorganisms, especially lactic acid bacteria (LAB). The purpose of this study was to isolate and identify LAB from naniura, as well as to carry out morphological characteristics, Gram staining, and sensitivity tests to several commonly used antibiotics. Isolation was carried out using MRS media in anaerobic conditions, while sensitivity tests were carried out using the disc diffusion method. The results showed that isolates from naniura had Gram-positive characteristics, rod-shaped, catalase negative, and showed varying inhibition zones against antibiotics. Some isolates showed resistance to amoxicillin and cefataxim, but were sensitive to erythromycin and gentamicin. These results indicate that LAB from naniura has potential as a probiotic candidate, but it is necessary to monitor the possibility of antibiotic resistance gene transfer.

This study examines the constitutional position of the President and Vice President in Indonesia following the four amendments to the 1945 Constitution between 1999 and 2002, focusing on how these reforms reshaped executive authority and accountability. It addresses the problem of excessive presidential dominance and unclear vice-presidential functions under the New Order regime, with research objectives to analyze the institutional, authority, accountability, and relational dimensions of the amended constitutional framework. Employing a normative doctrinal method through statute and conceptual approaches, the study analyzes primary legal texts, scholarly articles, and tertiary materials using descriptive-analytical techniques. The main findings reveal that the introduction of direct joint elections, strict two-term limits, impeachment mechanisms, and the establishment of the Constitutional Court significantly strengthened checks and balances, clarified the Vice President’s supportive and succession roles, and redistributed legislative powers to the DPR. These reforms created a more balanced separation of powers and enhanced democratic legitimacy while also highlighting emerging challenges in institutional capture and democratic backsliding. In conclusion, Indonesia’s gradualist constitutional reform successfully transformed an authoritarian executive into a more accountable presidential system, though ongoing vigilance and potential further amendments are necessary to consolidate democratic gains.

The Ripple Mill machine is one of the vital components in a Palm Oil Mill (PKS) that functions to separate the palm kernel from its shell. This process is very important because the quality and quantity of the palm kernel produced will directly affect the economic value and production efficiency in the palm oil industry. At PTPN IV Regional II Plantation Unit and Adolina PKS, various technical problems were found that caused a decrease in machine performance, including rotor bars and square bars that experienced wear due to age and improper machine settings. In addition, other damage that often occurs is a broken van belt due to age and excessive tension, feeder motor dysfunction caused by excessive load, and motor overheating that occurs due to age and high workload. To overcome these problems, this study uses the Failure Mode and Effect Analysis (FMEA) method. This method aims to identify various potential failures, assess the severity, frequency of occurrence, and detection capability, so that the Risk Priority Number (RPN) value can be calculated as a basis for repair priorities. The results showed that worn rotor bars and worn square bars had the highest RPN values, each at 280, equivalent to 40.23% of the total identified risks. This indicates that these two components are critical points requiring immediate repair and maintenance attention. Applying FMEA in this context provides tangible benefits, including helping the company formulate a more targeted maintenance strategy, reducing the risk of recurring damage, and minimizing downtime that impacts production. With more systematic maintenance, operational efficiency can be improved while extending the lifespan of the Ripple Mill machine.

This study explores the representation of women in the Indonesian and Javanese languages through a contextual linguistic approach. The analysis focuses on three main domains: the symbolic representation of women in nationalist discourse, gender representation in advertising language, and the semantic shift of domestic vocabulary in Javanese that manifests in the form of pejorative expressions. Employing a descriptive qualitative method, the findings reveal that language functions not only as a tool of communication but also as a means of shaping gender ideology. Terms such as ibu pertiwi (motherland) and ibu kota (capital city) indicate a symbolic appreciation of women’s roles within the national framework. Conversely, diction such as cantik (beautiful) and elegan (elegant) in advertisements reflect socially constructed gender identities. Furthermore, in the Javanese language, the transformation of domestic vocabulary into derogatory expressions—such as kitchen-related terms becoming insults—illustrates a symbolic imbalance concerning women’s domestic roles. This study emphasizes the importance of critical awareness in language use, particularly in shaping inclusive and gender-equal narratives.
