Implementation of a WhatsApp-based Canteen Menu Chatbot using TF–IDF and cosine similarity: A case study of employees at Matahari Department Store, Sunrise Mall and Mojokerto
This study addresses the limitations of traditional workplace canteen menu information sharing, such as noticeboards and verbal announcements, which can cause delays in shift-based settings. A WhatsApp-based canteen menu chatbot was designed, implemented, and evaluated for Matahari Department Store Sunrise Mall Mojokerto (Indonesia) using Cosine Similarity for text matching. The system integrates WhatsApp messaging via the WhatsApp API with an application server and an admin web panel built on Laravel–MySQL, enabling the management of daily menus, canteen schedules, FAQ patterns, user access, and conversation logs. User queries and stored question patterns were preprocessed (lowercasing, cleaning, tokenization), vectorized using TF–IDF, and matched using Cosine Similarity with a 0.6 acceptance threshold to route responses into three classes (Static, Menu, or Schedule) or a fallback reply. Functional verification through black-box testing confirmed the correct operation of core modules and end-to-end message handling. Similarity computation was validated against a manual example (0.816 vs. 0.8165). Robustness testing on 50 employee questions (25 standard and 25 informal/misspelled) achieved 92% accuracy (46/50); retrieval effectiveness measured as micro-F1 across the three response classes was approximately 0.95, with four queries treated as unmatched. A baseline comparison showed that Cosine Similarity was more tolerant to paraphrasing than SQL keyword matching. The case study ran from August to November 2025, and conversation logs were used during the maintenance phase to refine FAQ patterns and improve coverage. Overall, the chatbot offers a lightweight and deployable solution for routine, time-sensitive internal information services in retail workplaces.

Comparative simulation analysis of the economics of unit commitment to determine the cost of supplying electricity in simple generating systems in the Bengkulu region
An efficient electrical system is essential to meet the energy needs of the community without incurring high operational costs. This study aims to compare the total operational costs of power plants during three extreme time periods: low load (00:00–05:00), medium load (06:00–18:00), and high load (19:00–23:00), and to determine the most efficient combination of power plants using the Unit Commitment (UC) method based on priority list techniques. The study was conducted on the Bengkulu regional power system with the assumption of zero startup costs due to data limitations. Simulation results show that coal-fired power plants (IPP), hydroelectric power plants, and micro-hydro power plants serve as the base load power plants that are always active due to their low operational costs, while diesel power plants are only used as supplements when load exceeds the capacity of the main power plants. The lowest total operational cost occurs during low-load periods at Rp 40,936,446/hour, while the highest cost occurs during peak-load periods at Rp 65,040,329/hour. This finding confirms that optimizing the combination of power plants based on cost efficiency can significantly reduce operational expenses. In the future, it is expected that the electricity system can adopt smart grid technology to reduce, even eliminate, the use of inefficient diesel power plants.

However, its inherent brittleness limits its application in high-impact environments. This study investigates the incorporation of cellulose nanocrystals (CNCs) into PMMA to significantly enhance its toughness without compromising its optical clarity. By reinforcing PMMA with CNCs, the nanocomposites exhibited a remarkable 190% increase in toughness while maintaining 90% optical transparency. The innovation lies in achieving a balance between toughness and transparency through controlled CNC dispersion within the PMMA matrix, which minimizes excessive bonding that could lead to brittleness. Proper CNC dispersion was achieved through in-situ polymerization, allowing the nanocrystals to interact with the polymer matrix through van der Waals forces rather than covalent bonds. This approach reduces stress concentration and mitigates the formation of defects in the polymer matrix, ultimately leading to a tougher, more flexible material. In addition to enhancing mechanical properties, this study underscores the importance of controlling CNC content to preserve the intrinsic optical transparency of PMMA. These findings open new possibilities for CNC-reinforced PMMA in advanced applications that demand high mechanical performance coupled with excellent optical properties, extending its use in fields such as medical devices, protective coatings, and transparent structural materials.

Modified sorbents based on natural mineral and its mechanical properties
The use of modified sorbents based on natural minerals, widely distributed in Kazakhstan, is a promising direction. This direction is related to the development of domestic ion-exchange materials. The republic lacks its own production of synthetic sorbents. The environmental situation in the regions of uranium ore mining and processing is also important. Moreover, the application of synthetic sorbents is not always justified due to their high cost, while the use of natural sorbents is limited by their low sorption capacity. The development of modified ion-exchange materials based on a combination of these is a pressing issue for various industries. Research has been conducted on the choice of modification methods for natural sorbents and the evaluation of their sorption capacity after modification. The modification of natural minerals zeolite and shungite using the "solid-phase extractants" method was carried out in two stages. At the first stage, the modification was performed with organic extractants and compositions based on them, and at the second stage with phosphoric acid in combination with polyacrylamide. The natural sorbents used were zeolite from the Kusmuryn deposit and shungite from the Koksu deposit, following preliminary flotation. The mechanical strength of sorbents modified by different methods was compared with the original ion-exchange materials. Studies of the sorption process have shown that the best results for uranium sorption were obtained with modified sorbents: zeolite modified with a mixture of extractants Di-2-Ethylhexyl phosphoric acid (Di-2-EHPA), Tributyl phosphate (TBP), kerosene, and shungite modified with phosphoric acid in the presence of Polyacrylamide (PAA).

A Study on the efficiency of organic activator application to process refractory hard-to-beneficiate raw materials
Polymetallic ores with complex mineralogical compositions pose significant challenges in flotation beneficiation, often resulting in suboptimal separation and recovery of valuable minerals. This study aims to analyse the effectiveness of alkyl benzene sulfonic acid (ABSA) as a frothing activator in improving the flotation performance and mineral recovery of polymetallic ore. It presents the results of flotation beneficiation experiments for polymetallic ore of complex mineralogical composition. Experiments were conducted on polymetallic ore samples using ABSA as the frothing activator in the flotation process. The performance was evaluated based on recovery rates and separation efficiency, comparing the results with standard floating frothing agents. The findings showed the highest efficiency of ABSA application for samples of mixed-type ores in increasing the recovery of gold, copper, zinc and lead in the collective concentrates of flotation beneficiation. ABSA activator promotes additional cleaning of fragments containing valuable metals from oxide films and coatings and the transfer of valuable metals' microparticles due to the organics' adsorption properties and the formation of metal-carbon bonds. Another effect of using this reagent is there was an increase in concentrate mass yield while maintaining the quality parameters. A similar effect was observed for beneficiation of copper ore with complex composition - copper recovery in the main concentrate increased. Selective flotation with the development of gold concentrate from hard-to-beneficiate polymetallic ore also showed a significant increase in gold recovery with ABSA pretreatment.

Enhancing STEM education through peeragogy: Exploring the impact of demographics factor
Despite the growing recognition of the peeragogy learning approach, which emphasizes students' active participation and responsibility in their learning, there is still a gap in understanding how demographic factors influence its effectiveness in Science, Technology, Engineering and Mathematics (STEM) education. While pedagogy aims to harness the individual potential to promote independence, collaboration, and deep understanding, few studies have been conducted on how different demographic factors impact the success of this approach. This study aims to identify the trends in the peeragogy learning approach among students for STEM subjects in the Upper Secondary Vocational Program (PVMA) stream based on demographic factors such as gender, STEM subjects, and socioeconomic status (SES). The design of this study is survey research that employs a quantitative approach, and a modified set of questionnaires derived from past studies was used as the research instrument. A total of 158 students enrolled in STEM subjects under the PVMA stream at secondary schools were randomly selected as the study samples. The results indicate that most students in STEM subjects under the PVMA stream prefer a goal-oriented peeragogy learning approach, a consistent trend across both genders. Socioeconomic status also plays a role, with students from varying household income levels generally preferring the self-directed peeragogy learning approach. Different STEM subjects and SES affect PVMA students' choice of peeragogy learning approaches. In conclusion, educational institutions can improve the effectiveness of peeragogy in STEM education for PVMA students by promoting equitable learning opportunities for different SES and developing peeragogy strategies based on different STEM subjects.

Synthesis Optimization of Cathode Precursor Ni0,5 Mn0,4 Co0.1 (OH)2 with Coprecipitation Method
The use of conventional fuels such from fossils sourced is non-renewable energy, which makes this energy source less environmentally friendly. The battery that is nowadays used widely is the Lithium-Ion type with variations in the type of electrode. Electrodes have an important role in battery performance, especially at the cathode. Predecessor cathode types such as LiCoO2, LiMnO, and LiNiCo have various disadvantages due to their dangerous nature, insufficient capacity, and poor stability. NMC cathode (NiMnCo), in this case, NMC541 is presented to overcome these deficiencies. The process of making NMC541 cathode can be done by various synthesis methods, one of which is Co-precipitation. The synthesis parameter directly influences the performance of the cathode precursor produced, especially on its microstructure. For that, we try to optimize the synthesis parameters, such as Stirring Speed, and Aging time. The result said that samples with 900 Rpm stirring speed give the best product precursor along to their small size particle and good conductivity. Meanwhile, Aging co-precipitation doesn’t significantly affect coprecipitation precursor products.
