Indonesia is one of the countries with a significant number of laundry services, which has led to the emergence of numerous companies engaged in the production of high-quality softener products. This extensive softener production has resulted in a considerable surplus of the product, which can potentially harm the environment. This study aimed to process the excess products produced by the softener industry into vehicle shampoo and LAS (Linear Alkylbenzene Sulfonate), the main component of vehicle shampoo. We will achieve this through trial-and-error mixing methods and optimal variations. We aim to create products with sales value that the public can use to wash vehicles at a more economical price while maintaining quality comparable to commercial products. The optimal variation results obtained from this research were 40 ml of fragrance, 50 ml of Sodium Laureth Sulfate (SLES) Texapon, and 40 g of LAS, with test results of pH 7.92 and density 1.025 g.cm-3. The viscosity was found to be 2.41 Pa.s, the foaming power was 91.67%, and the corrosivity was 0.09291 mm/year. These results showed that the vehicle shampoo meets corrosion resistance standards. 

Indonesian law reform faces persistent challenges stemming from fragmented human resource capacity, which undermines the coherence and effectiveness of justice delivery. This study critically examines the interplay between human resource development and the success of legal reform in Indonesia, emphasizing the urgent need to address systemic inefficiencies and skill gaps. As globalization and complex socio-legal issues demand more sophisticated legal systems, the pressure on Indonesia’s legal institutions to enhance their human resource capabilities has intensified. The novelty of this research lies in its focused analysis of human resource capacity as a critical yet underexplored dimension of Indonesian law reform. By employing a socio-legal methodology, the study identifies key factors contributing to fragmentation, including uneven competency levels, inadequate training, and lack of coordination among legal institutions. It further evaluates the role of education, professional development, and policy frameworks in fostering a coherent and competent legal workforce. The findings demonstrate that a robust, well-coordinated human resource strategy is essential for advancing legal reforms and delivering justice effectively. This research contributes to the discourse by proposing actionable solutions, including curriculum reforms, capacity-building initiatives, and collaborative networks among legal practitioners, academics, and policymakers. By addressing the critical gap in human resource capacity, this study provides a pathway for achieving a coherent legal system that upholds justice and aligns with Indonesia’s broader development goals.

Ship accidents are still a problem in the maritime industry even though the BRM training program has been implemented since 2011. Analysis of several incidents noted that the human error factor was ranked highest. SA as an important aspect in BRM has not been applied properly as a related cause of the incident. For this reason, this study aims to foster and deepen the understanding of SA to the Ship's Crew and then apply it in BRM so that navigation safety is always maintained and similar incidents do not occur in the future. The study used a literature study method, by exploring references to maritime publications, previous journals, books and relevant sources. The results of the study, SA can be formed by mobilizing all five senses well combined with an understanding of the surrounding environment and experience. SA consists of 3 levels, each of which is interrelated and continuous, namely; Perception (Level 1), Understanding (Level 2) and Projection (level 3).

This study is a literature review aimed at understanding the contribution of physical education teachers in shaping students' character. The method used in this research is a literature review, with research sources obtained from various references such as journals, books, documentation, the internet, libraries, and other relevant sources. The data collection technique for this literature review involved gathering various references and citations relevant to the research topic, utilizing the Google Scholar database by entering the keyword “contribution of physical education teachers in building student character.” The database search yielded 10 articles published between 2016 and 2022 that are relevant to the focus of this study. The findings indicate that physical education plays a significant role in shaping and instilling character in students. It can be concluded that the contribution of physical education teachers is currently at a moderate level in the process of character development in students. Therefore, it is expected that physical education teachers will further enhance their contributions to the implementation of character education.

Time Schedule is used as a guide and control tool for work execution time and productivity of workers, work tools on the project. In terms of productivity control, there are several aspects involved in the monitoring system, such as materials, tools, resources, and scheduling of project activities. Scheduling is the arrangement of resources to complete tasks in achieving targets. by involving components of activities, and time, In order to determine the optimal scheduling and budget. in accordance with time and cost limitations, this study uses the PDM (Precedence Diagram Method) method and the Crashing method through alternative scheduling with the addition of overtime of 1 hour, 2 hours, and 3 hours and knowing the acceleration cost. for each alternative. The results of the acceleration alternative with optimal costs are, alternative 1 adding 1 hour of overtime, the total cost decreased by 0.19% to Rp 3,067,337,201, -. This means that alternative 1 saves costs of Rp 5,984,598, - and is estimated to be one day faster to 119 days.

Kekurangan gizi menjadi masalah dalam tumbuh kembang anak yang dapat menyebabkan stunting, wasting, mudah terkena penyakit serta penurunan kecerdasan otak dan mental. Stunting di Kabupaten Sikka pada tahun 2022 sebesar 13,8% dari hasil e-PPGBM periode Bulan Agustus 2022. Untuk mengatasi masalah ini diperlukan klasifikasi status stunting yang sangat berpengaruh terhadap tumbuh kembang anak sehingga dapat memberikan perhatian lebih dari faktor stunting yang paling tinggi di suatu daerah. Dengan bertambahnya jumlah balita dan peningkatan kasus stunting, proses penyelesaian tidak bisa dilakukan dengan cepat. Selain itu, tidak semua petugas posyandu bisa menghitung status gizi balita secara manual. Oleh karena itu, agar orang tua dan kader posyandu dapat mengetahui kondisi anak lebih cepat, diperlukan sistem yang menggunakan model algoritma C4.5. Sistem ini mampu mengolah data numerik (kontinu) dan diskrit. Penelitian ini menggunakan 5 atribut, yaitu usia, inisiasi menyusui dini (Imd), tinggi badan, jenis kelamin, dan berat badan. Keistimewaan penelitian ini adalah penggunaan atribut Inisiasi Menyusui Dini (IMD) yang belum pernah digunakan dalam penelitian sebelumnya dengan data numerik. Penggunaan algoritma C4.5 untuk menganalisis hasil stunting dan menyajikannya dalam bentuk website menghasilkan tingkat akurasi yang tidak jauh berbeda dengan pembagian data latih dan data uji sebesar 92.68 dan 90.98% dengan Max Dept 10.

Hasil perbandingan prosentase kinerja processor dalam tiga kondisi dapat dilihat bahwa, rata-rata selilih yang paling besar berada pada pengujian perbandingan yang pertama. Karena perbadingan pada saat app tidak memainkan musik dengan app yang memainkan musik, processor memiliki selisih cenderung besar. Sedangkan pada pebandingan kedua kinerja processor cenderung stabil, hal ini dikarenakan pengujian perbandingan app sama-sama memainkan musik. Kemudian perbadingan ketiga processor hanya dibebankan intruksi untuk load data 1 track musik, sedangkan pembandingnya ditambakan load data musik dan effect. rata kinerja processor cenderung turun, hal ini dikarenakan saat app memainkan effect tidak menggunakan processor, namun app akan melakukan load code ke dalam memory.
