Comparative Study Of Monthly Electricity Consumption Clusterization Using K-Means and DBSCAN
Menganalisis pola konsumsi listrik sangat penting untuk meningkatkan efisiensi distribusi energi dan mengidentifikasi anomali seperti lonjakan yang tidak biasa atau kemungkinan pencurian listrik. Penelitian ini menyajikan analisis komparatif dua algoritma klaster—K-Means dan DBSCAN—dalam mengklasifikasikan penggunaan listrik bulanan pelanggan PT PLN (Persero) Rayon Ngunut, yang mencakup Kecamatan Rejotangan, Ngunut, Kalidawir, dan Pucanglaban. Dataset tersebut mencakup catatan konsumsi dari bulan November dan Desember 2024. Algoritma K-Means, yang menggunakan pendekatan klaster berbasis centroid, bekerja efektif pada dataset yang seragam, sementara DBSCAN, sebuah metode berbasis kepadatan, lebih mampu mengenali outlier dan pembentukan klaster yang tidak sferis. Kinerja kedua algoritma dievaluasi menggunakan Akurasi, Mean Squared Error (MSE), Presisi, Recall, dan F1-Score. Hasil eksperimen menunjukkan bahwa K-Means mencapai akurasi 96%, MSE 0,0400, presisi 0,71, recall 1,00, dan skor F1 0,83. Sebaliknya, DBSCAN mencapai akurasi 76%, MSE 0,2400, presisi 0,29, recall 1,00, dan skor F1 0,45. Hasil ini menunjukkan bahwa K-Means menghasilkan klaster yang lebih kompak dan konsisten, sementara DBSCAN lebih unggul dalam mengidentifikasi anomali, dengan total mendeteksi 17 outlier. Akibatnya, K-Means dianggap lebih cocok untuk pengelompokan konsumsi yang stabil, sedangkan DBSCAN direkomendasikan untuk tujuan deteksi anomali. Temuan ini diharapkan dapat membantu PT PLN (Persero) dalam mengembangkan strategi berbasis data dan adaptif untuk manajemen energi yang lebih efisien.

The Role of Lactobacillus plantarum in Enhancing the Physical Quality and pH of Water Hyacinth (Eichhornia crassipes) Silage
This research investigated the impact of supplementing water hyacinth (Eichhornia crassipes) silage with Lactiplantibacillus plantarum on its physical properties (pH, odor, texture, color, and fungal growth) as well as palatability. A Completely Randomized Design (CRD) was employed with three treatments and six replications: P0 (control, no L. plantarum), P1 (L. plantarum at 10⁵ CFU/ml), and P2 (L. plantarum at 10⁶ CFU/ml). The variables measured were pH, color, aroma, texture, fungal presence, and palatability. Findings revealed that L. plantarum supplementation significantly influenced (p < 0.05) the color of the silage, but had no significant effect on pH, aroma, texture, fungal development, or palatability. The mean pH values for P1 and P2 were 4.1 and 4.2, respectively, compared with 4.0 in P0. In terms of palatability, P2 produced the highest intake (201.5 g), followed by P1 (118.6 g), whereas P0 showed minimal consumption. Overall, the results suggest that higher concentrations of L. plantarum improve the visual quality of water hyacinth silage, but provide limited enhancement of other physical attributes and palatability.

Sensitivity Test of Clove Leaf Essential Oil (Syzygium aromaticum) Against Heterotrophic Bacteria Isolated from Food Products
This study aimed to evaluate the antibacterial activity of clove leaf essential oil (Syzygium aromaticum) against heterotrophic bacteria isolated from food products. Clove leaves were collected from Malang Regency, Indonesia, and the essential oil was extracted via steam-water distillation. Bacterial isolates were obtained from food samples using serial dilution and pour plate techniques. Antibacterial activity was assessed using the agar diffusion method at three oil concentrations (50%, 75%, and 100%), with Amoxicillin trihydrate as the positive control and sterile distilled water as the negative control. The morphological characteristics of the isolates were documented, and inhibition zones were measured. Results indicated that inhibition strength increased with oil concentration up to 75%, with the largest numerical inhibition observed against isolate K2 at 100% concentration (31.3 mm), approaching the positive control’s efficacy. Statistical analyses confirmed that differences among treatments were significant (p < 0.001), except between 75% and 100% concentrations, suggesting a plateau in activity beyond the minimum inhibitory concentration. The findings highlight clove leaf essential oil’s potential as a natural antibacterial agent for food preservation, offering an environmentally sustainable alternative to synthetic antimicrobials. However, in vitro conditions may not fully represent performance in real food matrices, warranting further research on its application, stability, sensory effects, and synergistic combinations with other natural antimicrobials.

Music Communication in Juicy Luicy’s Lyrics: Emotional Voices of Generation Z
This study aims to analyze the emotional representation in the lyrics of Juicy Luicy’s popular songs among Generation Z. Employing Roland Barthes’ semiotic framework and Stuart Hall’s theory of representation, this research explores how emotional meanings are constructed through linguistic and symbolic signs in the lyrics and how Generation Z audiences interpret them based on their social context. The study focuses on four songs: “Lantas”, “Tanpa Tergesa”, “Lampu Kuning”, and “Sialan", selected for their digital popularity and emotional resonance on platforms Spotify and YouTube. The findings reveal that the lyrics represent emotions such as dilemma, regret, uncertainty, and loss through simple diction, visual metaphors, and accessible symbols. These songs deliver emotional depth not only on a literal level but also connotatively, forming cultural myths around love and longing. Generation Z decodes these lyrics through the lens of their personal experiences, treating them as a reflective space for articulating emotional identity. Moreover, the lyrics serve as a medium for managing emotional stress and building social connections through shared empathy. Thus, the study affirms that Juicy Luicy’s lyrics function as a form of emotional communication and cultural representation in the lives of Generation Z.
