Pengaruh Kinerja Ekonomi dan Kinerja Lingkungan Hidup Terhadap Nilai Perusahaan
No full textThis study explores the relationship between economic and environmental performance and firm value in the consumer non-cyclical sector listed on the Indonesia Stock Exchange during 2020–2023. The sample consists of companies that consistently published sustainability reports. Economic performance is measured using Economic Value Added (EVA) is a comprehensive and to reflect long-term value creation, Meanwhile, environmental performance is evaluated based on ESG ratings published by the BGK Foundation. To determine firm value, Tobin’s Q is used as the main indicator, with leverage introduced as a control factor to account for capital structure influence. A quantitative method is employed, utilizing secondary data. A total of 18 companies were purposively selected, resulting in 72 observations over four years. The analysis uses panel data regression, beginning with descriptive statistics, followed by model selection, classical assumption tests, and hypothesis testing. The findings indicate that EVA has a significant positive effect on firm value, suggesting that strong economic performance enhances market valuation. In contrast, ESG scores are found to negatively influence firm value, implying that higher environmental disclosures may not align with investor expectations in this context. Simultaneous testing confirms the overall significance of the independent variables, while leverage does not show a notable impact.Penelitian ini bertujuan untuk mengkaji pengaruh kinerja ekonomi dan kinerja lingkungan terhadap nilai perusahaan pada sektor barang konsumsi primer yang tercatat di Bursa Efek Indonesia selama periode 2020–2023.

Navigating Campus Traffic: Analysing the Impact of Land Use on Congestion at King Abdulaziz University, Jeddah, Saudi Arabia
No full textThe present research examines the correlation between land use and traffic congestion at King Abdulaziz University in Jeddah, Saudi Arabia. The authors analyze the Congestion Index Value (CIV) data and land use proportions to determine the main factors that contribute to congestion. Additionally, the authors examine how different land use arrangements affect traffic flow on the campus. The analysis employs both Ordinary Least Squares (OLS) and Geographically Weighted Regression (GWR) models to consider spatial variability. The findings demonstrate that specific purposes, such as hospitals, housing, areas designated for females, and central administrative structures, have a substantial impact on traffic flow. Furthermore, the presence of educational structures and their closeness to different entrances on campus are crucial determinants of congestion levels. The research indicates that strategically locating facilities and optimizing infrastructure near important entrances can reduce congestion and improve movement on campus. These insights offer essential direction to urban planners and university administrators in formulating efficient traffic management and sustainable urban development policies
Tidal Phenomena and GPS-Based Monitoring System for Sea Level Measurement
No full textMeasuring sea surface height in open waters is very important for understanding tidal patterns and ocean wave dynamics. Most of the instruments currently used are based on pressure or acoustic sensors and are generally placed on the coast, making them less effective for measurements in open waters. This research develops a sea surface height measurement system based on the U-Blox NEO-8M GPS, which is placed on a buoy to obtain real-time elevation data. This system consists of an Arduino Mega 2560, a GPS U-Blox NEO-8M, and a Micro SD storage module. The measurement data were analyzed using the Fourier method to identify the main components constituting the sea surface height. The test results show a Mean Tide Level (MTL) of 4.27 m, a High-Water Level (HWL) of 11.30 m, and a Low Water Level (LWL) of -6.90 m. Fourier analysis revealed eight main components that make up the sea surface height pattern, with the dominant component having a wave period of 4.29 hours and an amplitude of 6 m. The comparison between the measured data and the Fourier model resulted in an average difference of 1.0798 m, likely caused by the influence of satellite signals, multipath, and atmospheric conditions. The results of this study indicate that the GPS NEO-8M can be used as an alternative for monitoring sea surface height in open waters, although it still requires accuracy improvement through signal correction techniques and more precise geoid references

TECHNICAL ANALYSIS OF ADDING HOLES TO THE SKEG OF A TUGBOAT AND ITS EFFECTS ON FLOW AND RESISTANCE USING THE COMPUTATIONAL FLUID DYNAMICS METHOD
No full textTugboats play a crucial role in supporting the safety and operational efficiency of ports and offshore activities. One of the key components in tugboat design is the skeg, which serves to enhance directional stability and reduce yawing effects. This study aims to analyze the influence of the number of holes in the skeg on the flow characteristics and resistance of a tugboat. Three skeg variations were tested: a skeg without holes, a skeg with two holes, and a skeg with four holes, under two speed conditions, namely 10 knots and 15 knots. The observed parameters include wetted surface area, drag force, and longitudinal flow velocity (velocity u). The simulation results indicate that the skeg without holes produced the lowest drag values, at 22.570 N at 10 knots and 138.430 N at 15 knots, along with a more stable and streamlined flow pattern. In contrast, adding holes to the skeg resulted in increased drag and flow disturbances in the form of vortices and fluid separation. Therefore, the skeg without holes is considered more hydro dynamically optimal for improving the operational efficiency of tugboats.
Kapal tugboat berperan penting dalam mendukung keselamatan dan efisiensi operasional pelabuhan serta kegiatan lepas pantai. Salah satu komponen penting dalam desain tugboat adalah skeg, yang berfungsi meningkatkan stabilitas arah dan mengurangi efek yawing. Penelitian ini bertujuan menganalisis pengaruh jumlah lubang pada skeg terhadap karakteristik aliran dan hambatan kapal tugboat. Tiga variasi bentuk skeg diuji, yaitu skeg tanpa lubang, skeg dengan 2 lubang, dan skeg dengan 4 lubang, pada dua kondisi kecepatan, yaitu 10 knot dan 15 knot. Parameter yang diamati meliputi luas permukaan basah (wetted surface area), hambatan (drag), dan kecepatan aliran longitudinal (velocity u). Hasil simulasi menunjukkan bahwa model skeg tanpa lubang menghasilkan nilai hambatan paling rendah, yaitu 22.570 N pada 10 knot dan 138.430 N pada 15 knot, serta pola aliran yang lebih stabil dan streamline. Sebaliknya, penambahan lubang pada skeg menyebabkan peningkatan hambatan dan gangguan aliran berupa vortex serta separasi fluida. Dengan demikian, skeg tanpa lubang dinilai lebih optimal secara hidrodinamika untuk meningkatkan efisiensi operasional kapal tugboat
IDENTIFIKASI WASTE DEFECT DENGAN VALSAT DAN PEMBUATAN JADWAL MAINTENANCE UNTUK MENINGKATKAN AVAILABILITY DAN MENGURANGI DEFECT.
No full textThis research aims to identify and minimize waste in the join maple production process at PT MNO, an IKM (small and medium industry) company operating in the automotive component sector. A lean manufacturing approach was applied using Value Stream Mapping (VSM) to analyze the overall production flow. Furthermore, a Waste Assessment Questionnaire (WAQ) followed by a Waste Relationship Matrix (WRM) was used to determine the most dominant type of waste. The results indicate that defect waste is the main problem, leading to increased production time due to additional rework activities. Three types of defects were identified in join maple products, namely burnt defects, small head dimensions, and burr defects. The VALSAT approach using Quality Filter Mapping (QFM) revealed that burr defects were the most dominant, occurring in the cutting process at a rate of 1.26%, exceeding the company standard of 1%. Based on fishbone diagram analysis, the main causes of burr defects include corrective maintenance practices, the absence of a periodic tool replacement schedule, and weak implementation of the 5S/5R culture. The proposed improvements include daily tool inspections as preventive maintenance, the use of inspection check sheets, scheduled tool replacement, and the application of jidoka. The results show that the defect rate decreased from 1.26% to 0.88%, availability increased from 88% to 94%, performance efficiency rose from 63.76% to 80%, and quality improved from 98.73% to 99.34%, resulting in a 19.55% increase in Overall Equipment Effectiveness (OEE).Penelitian ini bertujuan untuk mengidentifikasi dan meminimalkan waste pada proses produksi Join Maple di PT Masindo, perusahaan yang bergerak di bidang industri komponen otomotif. Pendekatan Lean Manufacturing menggunakan metode Value Stream Mapping (VSM) digunakan untuk mengidentifikasi alur proses produksi. Penelitian ini juga menggunakan Value Stream Analysis Tool (VALSAT) sebagai alat untuk mengidentifikasi waste. Berdasarkan Waste Relationship Matrix (WRM), masalah utama yang ditemukan adalah waste defect, menyebabkan waktu produksi menjadi lebih lama akibat penambahan waktu rework. Sehingga hasil analisis WRM menunjukkan bahwa waste tertinggi berasal dari produk defect. Terdapat lima jenis defect pada produk join maple: gosong, dimensi kepala kecil, dan burry. Berdasarkan mapping tools dengan menggunakan Quality Filter Mapping (QFM), ditemukan bahwa defect burry menjadi defect paling dominan yang terjadi pada proses cutting, sebesar 1,26% yang melebihi standar perusahaan sebesar 1%. Berdasarkan fishbone diagram faktor utama defect burry disebabkan oleh maintanace yang bersifat corrective, belum adanya jadwal pergantian pahat berkala, dan minimnya budaya 5S/R. Solusi yang diusulkan adalah pembuatan jadwal pengecekan pahat harian dan checksheet pengecekan, jadwal pergantian pahat berkala, saran Jidouka pengasahan pahat guna mengurangi defect burry. Hasil improvement menunjukkan bahwa Availability produksi meningkat dan tingkat defect diharapkan dapat turun.
