Abstract

The plastics recycling industry plays a vital role in reducing the environmental impact of plastic waste. However, challenges such as high operating costs and low profit margins are hindering its growth. This article explores the application of lean production systems as a potential solution to improve operational efficiency and profitability in this industry. By reducing waste at various stages of production, such as energy consumption, raw materials and production time, lean has been shown to reduce operating costs by up to 10% in large-scale production. In addition, Lean enables companies to increase production capacity without significantly increasing costs. Despite the challenges associated with initial investment and organisational culture change, the long-term benefits of implementing Lean, such as increased profit margins and competitiveness, make it a highly relevant strategy for the plastics recycling industry.

Abstract

Intervensi spiritual merupakan bagian penting dari pendekatan holistik dalam perawatan paliatif, khususnya bagi pasien kanker yang sering mengalami kecemasan, depresi, dan krisis makna hidup. Namun, aspek spiritual masih sering terabaikan dalam praktik keperawatan. Oleh karena itu, penelitian ini bertujuan untuk mengkaji berbagai bentuk intervensi spiritual yang dilakukan oleh perawat serta efektivitasnya dalam mendukung kondisi psikologis pasien kanker yang menjalani perawatan paliatif. Penelitian ini menggunakan desain literature review dengan pendekatan deskriptif. Data diperoleh dari artikel ilmiah yang dipublikasikan dalam sepuluh tahun terakhir melalui basis data Google Scholar dan PubMed. Kriteria inklusi meliputi artikel yang membahas intervensi spiritual oleh perawat pada pasien kanker, sedangkan artikel non-empiris dan tidak relevan dikeluarkan. Sebanyak 12 artikel yang memenuhi kriteria dianalisis berdasarkan jenis intervensi, metode penelitian, dan hasil utama. Hasil analisis menunjukkan bahwa intervensi spiritual seperti terapi zikir, SEFT (Spiritual Emotional Freedom Technique), konseling spiritual, guided imagery and music, serta pendekatan berbasis budaya seperti Gayatri Mantram dan musik Rindik Bali efektif menurunkan kecemasan dan depresi, serta meningkatkan motivasi dan kualitas hidup pasien. Beberapa intervensi juga berdampak positif bagi caregiver. Intervensi spiritual yang dilakukan oleh perawat berkontribusi nyata dalam meningkatkan kesejahteraan psikologis dan spiritual pasien kanker dalam perawatan paliatif. Diperlukan pelatihan dan kebijakan yang mendukung agar intervensi ini dapat diterapkan secara optimal dalam praktik keperawatan.

Abstract

This study was conducted at SMP Negeri 9 Jambi City to determine the effect of the Problem-based Learning (PBL) model on mathematical literacy skills in the Pythagorean Theorem material. The quasi-experimental design was used with a non-equivalent pretest and posttest control group design. The researchers collected the mathematical literacy ability data using a description test instrument. Furthermore, the visual-verbal ability data was collected using a visual-verbal ability questionnaire. This research was conducted on the seventh-grade students, with 69 students divided into two classes (experimental and control classes). A random sampling technique determined the sample. Based on the two-way ANOVA test, applying the Problem-based Learning (PBL) model on students' mathematical literacy skills was an effect. There was an effect of visual-verbal ability on literacy skills.

Abstract

Sintesa biodiesel selama ini lebih banyak menggunakan katalis homogen berupa NaOH atau KOH. Penggunaan katalis homogen dalam pembuatan biodiesel memiliki beberapa kelemahan, diantaranya terbentuknya produk samping berupa sabun dan pemisahan produk biodiesel dengan katalis cukup sulit. Untuk mengatasi kelemahan tersebut, mulai dikembangkan penggunaan katalis heterogen (padat) untuk menggantikan katalis homogen (basa). Pembuatan katalis heterogen dapat dibuat dengan bahan yang ramah lingkungan dan relatif murah yakni limbah cangkang telur dan sekam padi yang menghasilkan katalis CaO/SiO2 melalui proses impregnasi. Penelitian ini memvariasikan rasio CaO/SiO2 (5:3, 5:5, dan 5,7) b/b serta waktu impregnasi (22, 23, dan 24) jam. Katalis terbaik dilihat dari yield dan mutu biodiesel yang dihasilkan. Hasil penelitian didapatkan hasil yield terbaik adalah 71,54% pada rasio 5:7 dengan waktu impregnasi 24 jam. Analisis GC dilakukan untuk mengetahui mutu biodiesel dan hasil yang di dapatkan sebesar 8,25%.

Abstract

Banjarmasin the "City of a Thousand Rivers" boasts rich cultural heritage shaped by its extensive river networks. These rivers not only define the city's geographic characteristics but also play a crucial role in the social, economic, and cultural life of its people. However, modernization has led to the gradual fading of these cultural values. To preserve and promote this invaluable heritage, a cultural development and preservation facility, the Banjarmasin Cultural Center, is proposed. This study aims to design a cultural center that harmonizes local cultural elements with the needs of modern society. The concept of "aruh ganal" (grand celebration) is adopted as the main design approach, where local culture is celebrated and expressed through modern architectural design. An analogy-based approach is used to translate Banjar cultural elements into the design. The result is a cultural center that strengthens Banjarmasin's identity as the "City of a Thousand Rivers" while ensuring the continued relevance of its local cultural heritage in the face of contemporary changes.

Abstract

This community service activity aims to increase the understanding and capacity of workers, especially Micro, Small, and Medium Enterprises (MSMEs) related to credit and banking guarantee practices from a normative and economic perspective, as well as their relevance to increasing workers' income in North Sumatra. The problems faced by partners include low legal and economic literacy in banking, limited understanding of credit guarantee mechanisms, and lack of optimal use of productive financing. The service methods used include educational and socialization activities through material presentations, interactive discussions, and evaluation of participants' understanding using pre-test and post-test. The material provided includes banking credit regulations, types of credit guarantees such as dependents and fiduciary guarantees, as well as strategies for the use of productive credit to increase income. The results of the activity showed an increase in participants' understanding of the normative aspects of credit and banking guarantees, as well as increased awareness in choosing and managing credit in a more productive and sustainable manner. This activity makes a practical contribution in the form of strengthening financial literacy and banking laws which is expected to encourage an increase in workers' income in an inclusive manner in North Sumatra.
