PT. Tirta Fresindo Jaya, specifically its Pasuruan plant as the producer of Pucuk Harum Tea beverage, requires a large supply of steam to support various production processes. This steam is used in the process of heating tea leaves, heating water through a heat exchanger, and heating chemicals and water in the cleaning in place (CIP) process. Steam pressure of 5 bar that is flowed to the process equipment will undergo condensation to produce condensate. To separate steam and condensate, steam traps are used, consisting of several types, namely mechanical, thermostatic, and thermodynamic. However, in operational practice, steam trap malfunctions often occur, either in the form of steam leaks that are wasted with condensate or failure to drain condensate from the system. This condition causes a decrease in the efficiency of the steam piping system and increases the workload of the boiler. As a result, fuel consumption and boiler feed water requirements become greater than ideal conditions. Therefore, this study aims to analyze the energy and operational losses caused by steam trap malfunctions, as well as evaluate their impact on boiler system performance and steam utilization efficiency at PT. Tirta Fresindo Jaya Pasuruan plant.      

Motivasi belajar merupakan faktor penting dalam keberhasilan pendidikan, khususnya bagi santri di pondok pesantren yang menghadapi jadwal padat dan tuntutan akademik tinggi. Kajian ini mengusung tema “Belajar Mantap, Hidup Hebat” untuk menekankan bahwa pembelajaran yang konsisten dan berorientasi spiritual dapat mendorong keberhasilan baik dalam dimensi duniawi maupun ukhrawi. Motivasi dipahami melalui tiga ranah, yaitu intrinsik, ekstrinsik, dan religius, dengan dorongan agar santri mampu mengintegrasikan ketiganya sehingga motivasi belajar tidak hanya bersumber dari insentif eksternal, tetapi juga dari kesadaran diri dan niat yang tulus karena Allah SWT. Tantangan umum—seperti manajemen waktu, adaptasi dengan kehidupan kolektif, godaan teknologi, tekanan prestasi, serta masalah kesehatan fisik dan mental—dibahas bersama solusi praktis, termasuk penggunaan teknik Pomodoro sebagai strategi manajemen waktu yang efektif. Kajian ini menegaskan pentingnya keseimbangan antara usaha, doa, dan istiqamah dalam menuntut ilmu, dengan tujuan memberdayakan santri agar mampu mempertahankan motivasi, mengatasi hambatan, serta mempersiapkan diri menjadi pribadi yang bermanfaat bagi masyarakat.

This research aims to see how the concept of utilitarianism is applied in Indonesia. The application of the theory of utilitarianism will be studied more deeply in terms of law enforcement in society. Of course, through this method it can be seen that utilities that are useful and benefit the whole community will have more value than a legal decision that only benefits each party. One figure, Jeremy Bentham, said that the aim of law must fulfill three aspects, namely Justice, Certainty and Benefit. Therefore, legal objectives must be met so that the regulations or legal products formed by law bearers are expected to fulfill these three aspects perfectly. However, the truth of these three aspects as the objectives of creating a legal product that must exist, must be examined more deeply, whether it is true that the law has perfectly created justice, has certainty, and must provide benefits to society. The data collection method was carried out by studying literacy and statutory regulations and conducting qualitative descriptive data analysis.  

This study aims to analyze the types of illocutional speech acts contained in the lyrics of the song Hati-Hati di Jalan karya Tulus. The background of this research is based on the importance of understanding song lyrics as a form of communication that is full of pragmatic meaning, especially in the context of emotions and interpersonal relationships. The method used is qualitative descriptive with a content analysis technique based on the theory of classification of illocutional speech acts by Searle. Data were taken from all song lyrics and analyzed based on five types of illocution speech acts, namely representative, directive, expressive, commissive, and declarative. The results of the study show that in the lyrics of this song there are four types of illocutional speech acts, namely representative, directive, expressive, and commissive, with a dominance of representative and expressive types. The act of speech reflects various communication functions such as expressing beliefs, expressing feelings, giving hope, and showing commitment. This research implies that song lyrics can be a valuable object of pragmatic study, as well as enriching the understanding of communication strategies through language in popular literary works. This study has limitations on the scope of a single song and the interpretation of the researcher, so it is recommended that the next study examine other songs to broaden the perspective.

Utilization of fermented layer chicken excreta as a feed medium for Black Soldier Fly (BSF) maggots is a sustainable solution for organic waste management. Chicken excreta contains 13-32% crude protein, but has disadvantages such as unbalanced nutrient composition and unpleasant odor. Fermentation of chicken excreta can improve maggot production performance by reducing pathogens, odor, and facilitating digestion. The growth medium of 50% excreta + 50% tofu dregs produced the highest PK, which was 34.34%. The lowest SK and LK were obtained from the growth medium of 50% excreta + 50% tofu dregs and 25% excreta + 75% tofu dregs. Based on physical conditions, the longest and heaviest maggot sizes were obtained from the growth medium of 50% excreta + 50% bran + 5 ml EM4. Meanwhile, the shortest maggots were obtained from the growth medium of 75% coconut dregs + 25% excreta and the lightest maggots were obtained from the growth medium of 100% excreta.

This study aims to optimize the implementation of the K-Nearest Neighbors (K-NN) algorithm for medical image classification by focusing on selecting the optimal KKK parameter and applying dimensionality reduction techniques to improve accuracy and efficiency. The data used was sourced from public medical image repositories such as The Cancer Imaging Archive (TCIA) and Medical Image Analysis datasets, covering various diseases, including brain tumors, lung cancer, and kidney lesions. The research process involves data collection, data preprocessing, dimensionality reduction using Principal Component Analysis (PCA), applying the K-NN algorithm with Euclidean, Minkowski, and Cosine distance metrics, and performance evaluation using accuracy, precision, recall, and F1-score. Experimental results demonstrate that K=5with the Euclidean distance metric provides the best performance, achieving an accuracy of 90%. Additionally, PCA effectively reduces computational time by 30% without significantly compromising accuracy. This study proves that K-NN is an effective method for medical image classification. However, further research is needed to integrate K-NN with deep learning models to enhance performance and feature extraction capabilities.
