This research utilizes waste from PLTU Tanjung Jati B Jepara, namely FABA (Fly ash Bottom Ash) as an alternative to fine and coarse aggregate. From this research, the physical properties of faba aggregate can be seen from the results of the faba aggregate sieve analysis test, which obtained a fineness modulus value of 1.74, which is included in the medium aggregate type. The water content of fine aggregate (fly ash) obtained a value of 3.63% and coarse aggregate (bottom ash) obtained a value of 1.5%. The fine aggregate sludge content (fly ash) obtained a value of 0%. The fine aggregate organic substance (fly ash) acquires a reddish brown NaOH color, therefore it must be washed before being used as a concrete mixture. The face dry specific gravity of fine aggregate (fly ash) obtained a value of 2.63 gr/cm2 and coarse aggregate 2.52 gr/cm2. From the data that has been obtained, faba aggregate is considered to have physical properties that meet the requirements for fine aggregate and can be used as a substitute for sand. The results of the final compressive strength of faba concrete and normal concrete at the age of 7 days and 28 days showed that the compressive strength of normal concrete (control) was higher than that of faba concrete. The standard deviation values ​​at the ages of 7 and 28 days are included in perfect working conditions because they have a standard deviation value of less than 3 MPa. From the results of the concrete flexural strength test, only the control concrete was 1;1.5 with a flexural strength of 4.18 MPa, which is close to SNI 2847:2013, namely with a minimum flexural strength of fs = 4.4 MPa. Normal concrete has a higher flexural strength than faba concrete. Based on tests carried out with the planned mix design, the 1:1.5 variation obtained the highest results.

The objective of this study is to evaluate the impact of load balancing implementation on website service performance to enhance system efficiency and reliability. The research object is a website accessed through seven service endpoints: Login, Homepage, Blog, About, Shop, Contact, and Post Checkout, with a total of 3,500 requests. The testing was conducted under two scenarios: a single server architecture and an architecture utilizing a load balancer (HAProxy) implementing the Round Robin algorithm. The testing method employed Apache JMeter to simulate load and measure various performance parameters, including average response time, throughput, standard deviation, bandwidth usage, average response size, and error rate. The results indicate that the use of a load balancer significantly reduced the average response time from 7,551 ms to 3,278 ms, increased throughput from 12.5 to 27.3 requests per second, and improved response time stability by reducing standard deviation across all endpoints. Bandwidth usage also increased without changes in average response size, with the error rate remaining at 0% in both scenarios. The study concludes that implementing load balancing with HAProxy effectively enhances website service performance in terms of efficiency, capacity, and system stability, and is recommended as a performance improvement solution in resource-constrained environments.

The growth of digital technology and social media platforms has promoted intercultural communication, especially in second language acquisition by non-native speakers. This study examines phonological deviations in the Indonesian pronunciation of SunnyDahye, a South Korean influencer who frequently uses the language in her TikTok content. Employing a descriptive qualitative approach, data were collected from five purposively selected videos based on the clarity of audio and frequency of Indonesian usage. The analysis focused on segmental (consonants and vowels) and suprasegmental (intonation and stress) features using the International Phonetic Alphabet (IPA). Findings reveal notable instances of phonological interference, including the substitution of the alveolar trill /r/ with /l/, mispronunciations of the schwa vowel /ə/ replaced with /e/ or /a/, and flat intonation patterns influenced by Korean prosody. These deviations are rooted in the phonological system of the Korean language, which lacks certain Indonesian phonemes and prosodic features. The results emphasize the influence of first language phonology on second language articulation and underscore the importance of incorporating contrastive phonetic analysis in Bahasa Indonesia instruction for foreign learners. The study contributes to broader discussions in applied linguistics and second language pedagogy, particularly for the Indonesian for Foreign Speakers (BIPA) program.

Structural failure in construction projects is a critical issue that not only endangers public safety but also triggers legal consequences for parties involved. This study explores mechanical structural failure from technical, legal, and professional responsibility perspectives. Technically, structural failures are often caused by inadequate planning, poor-quality materials, and improper construction practices. Legally, the Indonesian Construction Services Law (Law No. 2 of 2017) and the Indonesian Criminal Code (KUHP) provide a foundation for holding parties accountable, both civilly and criminally, especially when failures result in significant losses or casualties. The research also discusses the roles and responsibilities of construction consultants and contractors. Consultants are responsible for accurate design and oversight, while contractors must ensure implementation aligns with technical specifications and safety standards. Any negligence or deviation from duties by either party can lead to legal liability. This paper emphasizes the importance of integrating technical diligence with legal compliance to ensure the success and safety of construction projects.

The development of contemporary church music, as part of the dynamic life of Christian worship, has sparked various responses—both as a relevant cultural expression and as a potential theological deviation. Music that adopts popular styles and emotionally expressive forms is often considered effective in engaging younger generations, yet it also raises concerns about shifting the focus of worship from God to human experience. This article aims to theologically examine the presence of contemporary church music in light of biblical principles of Christian worship. The method used is a descriptive qualitative literature study, drawing from theological works and research published within the last five years. The findings show that although contemporary music can serve as an effective means of fostering congregational spirituality, it must be theologically tested to ensure that musical expression does not obscure the Christ-centered essence of worship. Therefore, the church is called to integrate contemporary music into liturgy with discernment and theological responsibility.

Research on the preservation of local culture amidst globalization emphasizes the importance of a systematic educational strategy aligned with government policy. The main focus of this study is the role of educational institutions in introducing and maintaining the sustainability of Simalungun culture, considering that the cultural knowledge of the younger generation is declining due to modernization and the influence of the media. The research objective was to develop and evaluate SIMALOKA, an artificial intelligence-based framework with a teacher-in-the-loop approach that integrates Simalungun language, arts, rituals, and crafts into both formal and non-formal curricula. The method used combines natural language processing to tag content, a knowledge graph to map cultural concepts and skills, and a multi-objective optimization algorithm to develop balanced learning modules according to the cultural calendar. The system was tested using a dataset containing 1,850 cultural learning objects and produced modules with an average cultural coverage deviation of 3.4%, a content relevance score of 0.92, and an engagement rate of 87.1%, superior to two state-of-the-art baseline models. The results show that the combination of AI-based optimization and human validation can maintain cultural authenticity while significantly increasing student participation. These findings strengthen the hypothesis that context-sensitive, technology-based curriculum design can strengthen local cultural identity without neglecting educational policy demands. The study's conclusions confirm that SIMALOKA is a large-scale model that can be adapted to other local cultures, providing important implications for policymakers, educators, and cultural organizations in maintaining the sustainability of cultural heritage. Future research directions are directed at assessing long-term retention, resource constraints, and cross-cultural adaptation to make cultural preservation more inclusive and effective.

This study aims to examine the application and deviation of conversational maxims in Grice's cooperative theory in the podcast "Sule and Rizwan". This podcast was chosen because it presents interactions full of humor, spontaneity, and communication dynamics that are interesting to study pragmatically. The research method used is descriptive qualitative with listening and note-taking techniques as data collection instruments. Data in the form of utterances containing maxims of quantity, quality, relevance, and method are analyzed based on Grice's cooperative principle. The results of the study show that the speakers in this podcast consciously or unconsciously apply the four Grice maxims, but also often deviate from them for the purpose of humor, satire, or dramatic effect. These deviations do not interfere with communication, but rather enrich the meaning and strengthen the appeal of the conversation. These findings indicate that violation of maxims in the context of entertainment is not a form of communication failure, but rather an effective pragmatic strategy.

This paper examines the story of King Saul seeking help from a medium in Endor as a tragic illustration of the spiritual downfall of a leader who was once chosen and anointed by God. In his distress and desperation, Saul chose a path that violated the law, marking his disconnection from God. This action not only shows a serious spiritual deviation, but also reveals the irony that a female medium becomes a means for God to deliver His judgment. It also explores Christian theological views on the practice of séances, including the moral and spiritual implications they bring. By comparing the historical and cultural background of Israel, and reviewing it from a biblical perspective, this paper emphasizes the importance of obedience to God's word and the dangers of involvement in the occult. The relevance of this story to the Christian life today serves as a reminder to remain steadfast in God's revelation and to distance ourselves from deviant spiritual practices. It also invites readers to reflect on the importance of maintaining spiritual integrity in facing the challenges of life.

The premeditated murder case involving Inspector General Ferdy Sambo has exposed various institutional pathologies in law enforcement institutions in Indonesia. This study aims to identify forms of bureaucratic deviation in these cases, such as protection of power, violation of professional ethics, attempts to obstruct justice, and the dominance of absolute power in the police structure. Using a qualitative approach and library research methods, this study analyzes scientific literature, legal documents, and media coverage. The findings indicate a systemic failure in internal supervision, weak accountability, and a strong culture of personal loyalty in a hierarchical and feudal bureaucratic structure. This shows that bureaucratic pathology is not solely caused by individuals, but is a product of an unhealthy organizational system with minimal transparency. This study emphasizes the importance of comprehensive structural and cultural reform in order to build credible, accountable, and professional legal institutions. This reform is crucial to forming a bureaucracy that is in the public interest and is able to uphold justice fairly and independently.
