The Influence of Students' Perception of Social Media and Learning Motivation on Their English Learning
Get PDFThis study explores the influence of students’ perception of social media and their learning motivation on English learning. As social media becomes increasingly prevalent in students’ daily lives, its role in education, especially language learning, deserves critical attention. This research aimed to examine how students perceive the use of social media in their learning process and how their motivation affects their English learning outcomes. A quantitative survey method was employed, involving 100 eighth-grade students from SMPN 10 Kota Serang. Data were collected through a questionnaire containing 30 items related to the three main variables: students’ perception of social media, learning motivation, and English learning. The findings indicate that both students’ perception of social media and learning motivation significantly influence their English learning. Students who have a positive perception of social media tend to show higher learning motivation, which contributes to better performance in English. These results suggest that the use of interactive digital platforms could enhance students’ engagement and learning outcomes in English education. Further research is recommended to explore the long-term impact of social media integration in language learning

Rancangan Aliran Proses dalam Upaya Meminimumkan Proses Non-Value Added melalui Value Stream Mapping pada UD Usaha Rezeki Prabot
Get PDFThe flow of process is a sequence of jobs or activities performed in producing goods and services. UD. Usaha Rezeki Prabot, a small-to-medium enterprise (SME) in furniture manufacturing, consistently faces a critical operational challenge: despite stable customer demand (853 units/year of panel door type 7), only 750 units (88%) are delivered on time, resulting in a 12% delay rate. This gap is not caused by insufficient labor or machinery, but by a fragmented production system riddled with non-value-added (NVA) activities particularly repetitive machine setup, excessive material handling, redundant measurements, and long waiting times that inflate lead time to 176.91 minutes per unit. Value Stream Mapping (VSM) is applied as a lean tool to visualize the entire material and information flow, identify dominant wastes (waiting, over-processing, and unnecessary motion), and redesign the workflow. Through the implementation of future-state mapping by grouping components with identical profiles into batch processing and eliminating redundant inspections the NVA time was reduced from 79.95 minutes (45.19%) to 16.07 minutes (15.93%), cutting total lead time by 43%. This study demonstrates that for SMEs like UD. Usaha Rezeki Prabot, sustainable productivity gains come not from capital investment, but from restructuring workflow based on frontline insights to eliminate systemic waste embedded in daily routines. The purpose of this mapping is to identify all types of waste along the Value Stream and to take a move in an attempt to eliminate the waste. The flow of process design with Value Stream Mapping approach enables the company to be able to minimize the non value added activities and to shorten the time taken in the process of making doors and to increase the productivity. The purpose of this Motion and Time study was to do a direct observation about time and movement of someone who is working. UD Rezki Prabot uses the VSM (Value Stream Mapping) to minimize the non value added process and to propose a design to improve the flow of process. The result of this study showed that the time of non value added activities decreased from 176.91 minutes to 100.9 minutes. The non value added activities decreased from 45.19% to 15.93% due to the decrease of non value added activities by sequencing the work activities that the machine does not need to be set up repeatedly

Get PDFPelabuhan Perikanan Nusantara (PPN) Sibolga, a key capture fisheries hub in North Sumatra, supports a range of services and activities for fishing stakeholders. Purse seine vessels, predominantly used by fishermen at PPN Sibolga, target pelagic species such as kawakawa (Euthynnus affinis), yellowfin tuna (Thunnus albacares), and skipjack tuna (Katsuwonus pelamis). This study analyzes income disparities among fishermen based on the profit-sharing system applied to purse seine vessels at PPN Sibolga. Conducted from March 4 to April 4, 2024, the study employed a survey method, collecting primary data on fish weight (kg), selling price (IDR), vessel size (GT), and operational costs, alongside secondary data on fishing gear statistics and regional information from PPN Sibolga. Data were analyzed descriptively to elucidate the income-sharing structure. Findings indicate that the average operational cost per trip for a purse seine vessel is IDR 199,458,550, with an average revenue of IDR 443,046,000 and a net profit of IDR 232,597,867. The profit-sharing system allocates 60% of the net profit (after fixed costs) to the vessel owner and 40% to the crew, with the skipper receiving 8.10%, senior crew (engineers, officers, cooks) 5.40%, supporting crew 4.05%, and regular crew 2.70%. The study reveals significant income disparities among crew members, driven by their roles and the established profit-sharing structure in purse seine operations at PPN Sibolg
