Abstract

Material Needs Estimation The plate used in the ship repair process is a major requirement of raw material supporting the shipping industry. We know that the amount of material is never right in a development, which often happens to be inadequate and has an impact on the disruption of a production process. The situation is inadequate to a need that the production process is obstructed or runs smoothly, excessive raw material procurement can cause high storage costs and investment in raw material supplies. Material is a construction project that covers 40-60% of the cost to be issued by the company. In this paper, an analysis of the material needs of PT. Multi Ocean Shipyard. So get results for MT. FORTUNE PASIFIC-XLIX can be known as ton of 20354.3kg. To reduce the set-up, and lead time costs and maximize operational efficiency and also inventory investment can be suppressed as low as possible. By using the MRP (Material Requirement Planning) method, it is possible to calculate the amount, cost and time of the MRP Form to know the order, volume and tonnage time.

Abstract

Diabetes is a chronic disease and can cause long-term complications if not handled properly. To prevent this, a machine learning model is needed to predict diabetes with high accuracy. This study aims to see the effect of reducing feature dimensions on model performance and to see the effect of data cleaning on model performance. This study used the Pima Indian Dataset, two models were created with different preprocessing stages. The first model was created without performing data cleansing, and the second model was created by performing data cleansing. After the next preprocessing stage, the number of features that produce the best performance is sought using Sequential Forward Selection and the model is drilled using the Support Vector Machine algorithm. After going through the training stage, the two models will be tested and their performance will be compared. The results showed that reducing the number of features made the model have better performance. And of the two types of models, the model that uses the data cleaning stage shows better performance.

Abstract

This research aims to evaluate the implementation of the nature school concept at Jogja Green School in supporting character development and soft skills in children with special needs. This study uses a qualitative approach with observation and interview methods, observing the interactions of students, teachers, and nature-based activities such as gardening and farming. The subjects of this research number 25 individuals, and the data analysis technique used is the Miles and Huberman analysis technique, with data collection techniques through interviews and observations. The results of the study showed that the activity was effective in teaching responsibility, discipline, empathy, and other social skills. In addition, nature-based learning has been shown to improve students' understanding of the subject matter in a more concrete and interactive way. Despite the challenges in adapting materials for students with diverse needs, the flexibility of learning methods at Jogja Green School provides opportunities for ABK to develop according to their abilities. This study concludes that the concept of nature schools can be an effective model in inclusive education, with a focus on character development and soft skills that are important for ABK in facing life's challenges.

Abstract

Mixed Hydroxide Precipitate (MHP), a metal precipitate with the dominant nickel and cobalt content in hydroxide compounds, can be leached as a lithium battery precursor. In this study, KMnO4 was used as an oxidant agent to increase the solubility of Ni and Co. The variation of the sulfuric acid concentration (0.5 - 1.5 M) as a leachate reagent, the concentration of KMnO4 (2.5 - 7.5 g/L), and the selective leaching temperature (60 - 80°C) were investigated. Solvent extraction using CYANEX 272 and D2EHPA was performed to separate the Ni, Co, and Mn. Atomic Absorption Spectrometry (AAS), Inductively coupled plasma mass (ICP-OES), and X-ray Fluorescence (XRF) were used to analyze the chemical compositions. At the same time, crystallographic analysis was observed with X-Ray Diffraction. It was observed that potassium permanganate increased the dissolution of Ni and Co to 91.3% and 85.4% but decreased the dissolution of Mn (37.53%) under the following conditions: 1.75 M sulfuric acid, 7.5 g/L potassium permanganate, and 60°C temperature. High purity of nickel crystal (99.64%) was observed with spontaneous nucleation due to the supersaturated nickel solution after solvent extraction with CYANEX 272. Thus, using permanganate ion as selective leaching of Ni and Co from Mn is promising.

Abstract

Penelitian ini mengkaji dampak keterlibatan mahasiswa dalam lebih dari satu organisasi terhadap perilaku prokrastinasi akademik. Dengan pendekatan kualitatif, wawancara dilakukan dengan mahasiswa aktif di berbagai organisasi untuk memahami pengalaman mereka. Hasil penelitian menunjukkan bahwa manajemen waktu yang buruk dan beban tugas organisasi yang berat menjadi penyebab utama penundaan dalam menyelesaikan tugas akademik, meskipun keterlibatan dalam organisasi membawa keuntungan seperti peningkatan keterampilan kepemimpinan dan kolaborasi, pengelolaan waktu yang tidak efektif dapat menghambat pencapaian akademik. Penelitian ini menekankan perlunya penerapan strategi manajemen waktu yang baik serta dukungan dari institusi pendidikan agar mahasiswa dapat menyeimbangkan komitmen organisasi dan tanggung jawab akademik. Temuan ini sejalan dengan studi terbaru yang menegaskan bahwa kemampuan mengelola waktu secara efektif sangat penting untuk keberhasilan akademik dan dapat mengurangi stres akibat prokrastinasi. Oleh karena itu, mahasiswa yang aktif dalam organisasi harus menyadari pentingnya pengelolaan waktu yang baik untuk meraih keberhasilan di kedua bidang tersebut. This study examines the impact of students' involvement in more than one organization on academic procrastination behavior. Using a qualitative approach, interviews were conducted with students active in various organizations to understand their experiences. The results showed that poor time management and heavy organizational task load were the main causes of procrastination in completing academic tasks, although involvement in organizations brings benefits such as improved leadership and collaboration skills, ineffective time management can hinder academic achievement. This study emphasizes the need for the implementation of good time management strategies as well as support from educational institutions for students to balance organizational commitments and academic responsibilities. This finding is in line with recent studies that confirm that the ability to manage time effectively is critical for academic success and can reduce stress due to procrastination. Therefore, students who are active in organizations should realize the importance of good time management to achieve success in both areas.

Abstract

Penggunaan bahasa yang baik dan efektif sangat penting dalam komunikasi, terutama dalam konteks media sosial. Dalam era digital saat ini, keterampilan berbahasa yang aktif, kreatif, produktif, dan reseptif menjadi sangat relevan. Salah satu fenomena yang mencerminkan dinamika bahasa modern adalah penggunaan singkatan. Singkatan, yang sering digunakan di platform media sosial seperti Instagram, memerlukan perhatian khusus terhadap tata bahasa untuk memastikan bahwa pesan yang disampaikan dapat dipahami dengan jelas dan diterima oleh pembaca. Penelitian ini bertujuan untuk memaparkan bentuk-bentuk singkatan yang digunakan di akun media sosial Instagram dan menjelaskan arti serta makna dari singkatan-singkatan tersebut. Metode penelitian yang digunakan adalah metode deskriptif kualitatif, yang bertujuan untuk memperoleh data asli dan mendalam. Data yang dikumpulkan berasal dari komentar pada akun Instagram yang berfokus pada seni dan hiburan, khususnya dari akun @Dagelan. Berdasarkan hasil penelitian, ditemukan sepuluh contoh komentar yang menggunakan singkatan. Singkatan-singkatan ini umumnya dibentuk dengan menggunakan huruf pertama dari setiap kata dalam frasa untuk menciptakan kata baru. Temuan ini menunjukkan bagaimana singkatan dapat membentuk konsep atau kata baru yang memudahkan komunikasi di platform media sosial, serta bagaimana pengetahuan tentang singkatan ini dapat meningkatkan pemahaman dan interaksi di dunia digital.
