Abstract

In the ever-evolving digital era, education faces unprecedented challenges and opportunities. Technology is now an integrated part of the learning process, providing various tools that can increase the effectiveness and efficiency of education. One technological innovation that has great potential to support educators is ChatGPT. This ability can be utilized by teachers for various purposes, including in making learning tools. With the help of ChatGPT, teachers can save time and energy in designing teaching materials, assignments and learning evaluations that suit students' needs (Kharis et al., 2024). The teachers at SMP PGRI 8 Sidoarjo have not made much use of technology that makes it easier for them to prepare learning tools. This can be seen from the results of initial observations which show that 71.4% of teachers have never used applications or technology that makes it easier to create learning tools. This Community Service implementation was carried out with the aim of introducing, socializing and assisting teachers in utilizing ChatGPT to develop learning tools more quickly, effectively and efficiently. The results of participant responses regarding the implementation of activities are measured by participant satisfaction, which is the average of participant satisfaction with the satisfaction indicator factors. In this activity, 84.46% of participants gave an average rating of very good to the statement items in the questionnaire, which can be interpreted as meaning that 84.46% of participants were very satisfied.

Abstract

The storage space for CO2 gas cylinders is inside the ship's accommodation, so there is a risk of danger if a leak occurs because the ship's accommodation has poor air circulation. This research is devoted to removing dangerous gases from the room. This research designs and modifies a tool that can detect CO2 levels and can provide a danger signal to the surroundings. This modification uses a Raspberry Pi Pico W microcontroller. This research method uses system design, a series of tools with wiring design and uses 2 test plans, namely: testing static and dynamic testing. Testing the precision of the sensor by reading the CO2 leak detector using a CO2 measuring instrument obtained an average error value of 3.5%. The error value is still categorized as a safe difference value and the prototype works according to the expected function. Testing the function of the tool results in values ​​for the MQ-135 buzzer and exhaust fan sensors which will turn on if the CO2 level is above 600 ppm in accordance with the safe threshold for CO2 levels in the air which has been set in the program. Telegram request bot testing can work well as expected. Testing the Telegram Receive bot can work well as expected. However, for testing Telegram bots, requests and receives are influenced by the internet network.

Abstract

The port terminal serves as a place for berthing, storing goods, and loading and unloading, which has the potential to jeopardize work safety. The implementation of Occupational Health and Safety (OHS) protects workers from workplace hazards. However, the lack of awareness of workers at the port in wearing Personal Protective Equipment (PPE) while working in the port area is still a problem. This study aims to identify the risks, impacts and efforts to overcome work accidents in the ship berthing process at Tanjung Perak Port Surabaya. Given the importance of using PPE in doing work at the port, work safety is a crucial aspect that must be considered. Using the HAZOPS (Hazard and Operability Study) method, this study identifies potential hazards and provides mitigation actions needed to reduce the risk of accidents in the ship berthing process. This study used purposive sampling technique with a total of 40 officers in the patrol and enforcement section at the Tanjung Perak Surabaya Syahbandar and Main Port Authority (KSOP) Office. Data collection methods are direct observation, documentation, and questionnaires. The results showed that the main factors causing work accidents were equipment failure, human error, and the environment. The highest percentage of accidents is caused by equipment failure, with 63% at the extreme level and 20% at the high level. Therefore, it is necessary to carry out risk control or risk mitigation in the form of routine maintenance on work tools at the port.

Abstract

Dalam prosedur komersial perdagangan internasional, para eksportir dan importir ingin melakukan proses jual beli yang dapat menguntungkan kedua belah pihak. Di satu sisi, importir akan memilih jenis pembayaran dengan biaya termurah dan pembayaran berjangka panjang dalam membayar barang yang dibelinya. Di sisi lainnya, eksportir akan lebih memilih pembayaran tunai yang merupakan jenis pembayaran paling menguntungkan dan jenis penagihan dengan risiko terkecil. Dengan adanya latar belakang negara yang berbeda baik dari segi politik, ekonomi, sosial, budaya, dan perbedaan mata uang yang memicu timbulnya kekhawatiran apabila salah satu pihak melanggar perjanjian yang telah disepakati pada dokumen sales contract. Penelitian ini bertujuan untuk menganalisis faktor-faktor yang memengaruhi pemilihan metode pembayaran dalam transaksi ekspor, yaitu letter of credit (L/C), document against payment (D/P), dan telegraphic transfer (TT). Menggunakan metode deskriptif kualitatif, data dikumpulkan melalui wawancara mendalam dengan perusahaan yang aktif dalam ekspor, dan dianalisis melalui reduksi data, penyajian, dan verifikasi. Subjek penelitian ini adalah perusahaan yang bergerak dalam transaksi ekspor, metode pembayaran yang dianalisis meliputi letter of credit (L/C), document against payment (D/P), telegraphic transfer (TT). Variabel yang diukur mencakup enam faktor dalam penentuan metode pembayaran yaitu: 1. keamanan pembayaran, 2. risiko pembayaran, 3. kecepatan transaksi, 4. biaya transaksi, 5. kepercayaan dan/atau hubungan bisnis, dan 6. perlindungan hukum. Hasil penelitian menunjukkan bahwa metode pembayaran yang tepat sangat penting untuk mengurangi risiko dan meningkatkan efisiensi dalam transaksi ekspor. Metode telegraphic transfer paling sering digunakan karena membutuhkan waktu singkat dan memiliki biaya transfer dana elektronik lebih rendah meskipun dari segi keamanan tidak sekuat metode letter of credit (L/C).

Abstract

Ships are a means of transportation used in maritime transport activities, yet maintaining propulsion stability and efficiency remains a critical challenge, especially for multi hull vessels such as trimarans operating under dynamic sea conditions. Conventional controllers such as PID and field oriented control (FOC) often struggle to adapt to fluctuating loads and external disturbances. This study addresses that gap by applying Sliding Mode Control (SMC) for brushless DC (BLDC) motor speed regulation on a trimaran prototype. The system employs an STM32 microcontroller integrated with voltage, current, and RPM sensors to provide real time monitoring and robust control. Both static and dynamic tests were conducted at various speed setpoints with artificial wave disturbances. The results indicate that the SMC based system effectively reduced RPM deviation from ±550 RPM in uncontrolled systems to as low as ±3–15 RPM, while current and voltage consumption remained stable within 5%. Furthermore, propulsion efficiency improved by approximately 17% compared to conventional PID control. The most stable performance was achieved at the 8000 RPM setpoint, where current consumption reached 3.9–4.1 A, lower than the 4.7 A observed in uncontrolled operation. However, system performance declined at 10,000 RPM due to nonlinear load effects. These findings demonstrate that SMC provides a robust, adaptive, and energy efficient solution for BLDC motor control in trimaran propulsion, offering significant advantages over traditional methods and serving as a foundation for further optimization in high speed applications.

Abstract

Vessel Traffic Service (VTS) plays an important role in maintaining the safety and order of ship traffic, especially in congested water areas such as the West Shipping Channel of Surabaya. With this system, it is hoped that the movement of ships can be more organized, so that the risk of accidents and violations can be minimized. However, the effectiveness of VTS in supporting the monitoring of the order of ship movement and berth areas still needs to be further studied. This study aims to analyze the effectiveness of Vessel Traffic Service (VTS) in supporting the monitoring of the order of ship movement and the berth area in the West Shipping Channel of Surabaya. This study uses a quantitative method with a simple linear regression approach. Data was collected through observation and analysis of secondary data, then processed using the SPSS 22 application. The results showed that the effectiveness of VTS had a significant effect on order monitoring, with a significance value of 0.001 less than 0.05. The value of the determination coefficient is 29.1% which means that the effectiveness of VTS contributes to the orderliness of ship movements and the berth area, and from the regression equation obtained it shows that every increase in the effectiveness of VTS by one unit will increase the monitoring of order by 0.470 units.

Abstract

Keselamatan kerja merupakan aspek penting dalam operasional kapal, khususnya pada awak kapal bagian mesin yang memiliki tingkat risiko kerja tinggi. Salah satu upaya pencegahan kecelakaan kerja adalah penerapan prosedur keselamatan yang disiplin. Penelitian ini bertujuan untuk menganalisis hubungan antara kedisiplinan dalam penerapan prosedur keselamatan dengan tingkat kecelakaan kerja, serta mengidentifikasi strategi yang efektif untuk meningkatkan kedisiplinan awak kapal. Penelitian ini menggunakan metode kuantitatif dengan pendekatan statistik inferensial. Sampel penelitian berjumlah 30 responden yang seluruhnya merupakan awak kapal bagian mesin KMP. Dharma Bahari Sumekar III. Data dikumpulkan melalui kuesioner dan dianalisis menggunakan uji statistik non-parametrik dengan bantuan pengolahan data layaknya SPSS.Hasil uji kualitas instrumen menunjukkan bahwa seluruh item kuesioner valid dan reliabel. Uji asumsi statistik menunjukkan data tidak berdistribusi normal, sehingga analisis hubungan menggunakan uji korelasi Spearman Rank dan analisis regresi linear sederhana. Hasil penelitian menunjukkan bahwa terdapat hubungan yang bersifat negatif antara kedisiplinan dalam penerapan prosedur keselamatan dengan tingkat kecelakaan kerja, namun hubungan tersebut tidak signifikan secara statistik pada taraf kepercayaan 95%. Selain itu, faktor-faktor seperti pengetahuan keselamatan, kesadaran akan pentingnya keselamatan kerja, motivasi, keteladanan pimpinan, serta pengawasan dan penegakan disiplin berperan dalam membentuk tingkat kedisiplinan awak kapal.Kesimpulan penelitian ini menunjukkan bahwa meskipun kedisiplinan memiliki kecenderungan menurunkan tingkat kecelakaan kerja, pengaruhnya belum terbukti signifikan secara statistik. Oleh karena itu, diperlukan strategi peningkatan kedisiplinan yang komprehensif melalui pembentukan budaya keselamatan kerja di lingkungan kapal.
