STRATEGI KELANGSUNGAN KINERJA K3 DI PERUSAHAAN MELALUI PEMENUHAN UNSUR K3 DI TEMPAT KERJA
Get PDFPenelitian ini bertujuan menganalisis pengaruh indikator Keselamatan dan Kesehatan Kerja (K3) terhadap keberlangsungan usaha serta merumuskan strategi efektif untuk mendukung operasional perusahaan melalui penerapan unsur K3 yang efisien dan tepat sasaran. Metode yang digunakan adalah pendekatan kuantitatif dengan data primer dari 76 responden yang terdiri atas jajaran direksi, manajemen, dan pekerja di Fasilitas ABC PT. XYZ. Analisis dilakukan menggunakan SPSS versi 31 dengan regresi linear berganda. Hasil penelitian menunjukkan bahwa penggunaan Alat Pelindung Diri (APD) dan peralatan keselamatan secara parsial tidak berpengaruh signifikan terhadap keberlangsungan usaha, sedangkan penerapan budaya disiplin K3 berpengaruh signifikan. Secara simultan, ketiga variabel tersebut berpengaruh bersama terhadap keberlangsungan usaha. Oleh karena itu, penerapan K3 harus dilakukan secara menyeluruh dan konsisten dengan kedisiplinan yang tinggi.

THE INFLUENCE OF SAFETY LEADERSHIP, EFFECTIVE COMMUNICATION, EMPLOYEE COMPETENCE, AND WORK CULTURE ON SAFETY BEHAVIOR AT THE JAMBARAN TIUNG BIRU CEPU CONSTRUCTION PROJECT OF PT ELNUSA FABRIKASI KONSTRUKSI
Get PDFThis study aims to examine the influence of safety leadership, effective communication, employee competence, and work culture on safety behavior. The research population consists of all employees in the construction business unit of the JTB Cepu construction project carried out by PT Elnusa Fabrikasi Konstruksi, totaling 60 people. Data analysis was conducted using a quantitative approach through Partial Least Squares Structural Equation Modeling (PLS-SEM) with the assistance of SmartPLS version 4 software. The results show that safety leadership and effective communication have no significant effect on safety behavior, while employee competence and work culture have a significant effect on safety behavior. These findings indicate that the formation of safe work behavior is more determined by individual capacity and organizational culture rather than structural approaches. Therefore, the company is advised to improve employees’ technical competencies and strengthen the internalization of a safety-oriented work culture
ANALISIS PENGELOLAAN PERSEDIAAN HYDRANAL SOLVENT PADA PT XYZ
Get PDFPT XYZ merupakan salah satu pabrik pupuk terbesar di Indonesia yang memiliki berbagai laboratorium pengujian, salah satunya Laboratorium Kimia. Salah satu bahan vital yang digunakan adalah Hydranal Solvent untuk metode analisa kadar air (Karl Fischer). Penelitian ini bertujuan untuk menghitung dan menganalisis perbandingan jumlah pemesanan optimal, frekuensi pemesanan, dan total biaya persediaan menggunakan 2 metode. Mengingat penggunaan Hydranal Solvent bersifat fluktuatif, penelitian ini menggunakan metode EOQ (Economic Order Quantity) Probabilistik dalam merencanakan persediaan, kemudian dibandingkan dengan metode yang dilakukan perusahaan dan POQ (Periodic Order Quantity) dan diharapkan dapat memberikan gambaran pendekatan yang lebih tepat dalam mengendalikan persediaan bahan kimia yang bersifat tidak pasti. Hasil dari analisis didapatkan metode EOQ Probabilistik yang mampu menekan biaya persediaan dengan jumlah pemesanan optimal 4,3243 liter, frekuensi pemesanan 7 kali, dan total biaya persediaan Rp 204.450.

Pola Asuh Orang Tua terhadap Kemampuan Bina Diri Anak Disabilitas Intelektual
Get PDFThis research aims to identify the type of parenting style applied and analyze the impact of parenting styles on children\u27s self-development abilities. The method used is a descriptive qualitative method, where data is collected through interviews, observations, and documentation on parents of students at the Jember State Special School, using a purposive sampling technique. The results of the research show that the parenting style provided by two parents on the self-development abilities of children with intellectual disabilities at the Jember State Special School, namely that parent R applies a combination of authoritarian parenting and democratic parenting. This parenting style can help develop children\u27s self-development abilities well. Meanwhile, M\u27s parents use a permissive parenting style, which can hinder the child\u27s self-development skills. The conclusion of this research shows that parenting styles have an essential role in the self-development abilities of children with intellectual disabilities at the Jember State Special School.

Pengaruh Metode Solmisasi terhadap Kemampuan Bermusik melalui Pianika pada Siswa Disabilitas Netra
Get PDFThis study aims to determine the effect of the solmization method in learning pianica on the musical abilities of students with visual impairments at SLB Branjangan Jember. This study used the Single Subject Research (SSR) method with an A-B design. The baseline phase (A) was conducted for five sessions to observe students\u27 initial musical abilities without treatment. Furthermore, in the intervention phase (B), which lasted for seven sessions, students were given learning using pianica with the solmization method. Data were analyzed to see changes in students\u27 abilities between the two phases. The results showed that students experienced a significant increase in musical skills after the intervention. In the baseline phase, students had difficulty recognizing and playing notes correctly. However, students could identify and play notes better after using the pianica with the solmization approach. In conclusion, applying solmization in pianica learning can be an effective method for students with visual impairments to improve their musical abilities. This study contributes to more inclusive music learning for students with visual impairments. By implementing solmization and using the pianica, students can learn music more easily and in a structured manner according to their needs.

Learning Obstacle Sebagai Indikator Krisis Konseptual dalam Pembelajaran Bangun Ruang Sisi Datar
Get PDFThis study aims to identify the Learning obstacles experienced by students in learning quadrilaterals and to analyze how these obstacles indicate the emergence of a conceptual crisis. The method used is a descriptive qualitative approach involving junior high school students as research subjects. Data were collected through diagnostic tests, interviews, and classroom observations to explore students’ learning difficulties in greater depth. The findings show that students still encounter various types of Learning obstacles, including ontogenic, epistemological, and didactical obstacles. These obstacles are evident in students’ inability to understand basic concepts, difficulties in connecting different representations of geometric figures, and the mismatch between teachers’ instructional strategies and students’ learning characteristics. These conditions indicate the presence of a conceptual crisis that may hinder students’ understanding of more complex mathematical concepts. In conclusion, this study emphasizes that the Learning obstacles identified are influenced not only by students’ initial abilities but also by instructional resources and the teaching approaches used. The findings contribute theoretically to the discussion of Learning obstacles in mathematics education and provide practical recommendations for teachers in designing geometry instruction that is more contextual, interactive, and conceptually oriented.
