<![CDATA[Telah banyak dikembangkan sistem pemantauan terhadap kondisi kesehatan suatu jembatan atau Bridge Structural Health Monitoring System (BSHMS) menggunakan konsep Wireless Sensor Network (WSN). Salah satu komponen terpenting yang digunakan dalam BSHMS tersebut adalah node sensor nirkabel. Implementasi perangkat node sensor nirkabel pada BSHMS terdiri dari beberapa sub-sistem yang dicatu menggunakan sumber daya untuk dapat mengirimkan data secara terus-menerus.Pengiriman data secara terus-menerus oleh node sensor menyebabkan konsumsi energi yang besar pada sisi node sehingga dapat mengurangi lifetime. Sebuah studi tentang implementasi mode sleep-wake-up scheduling pada perangkat keras node sensor telah dilakukan dalam penelitian ini guna mengurangi konsumsi daya dan memperpanjang lifetime node sensor.Satu sistem jaringan sensor nirkabel terdiri dari node sensor dan node koordinator telah dirancang untuk aplikasi BSHMS dengan mengimplementasikan mode sleep/wake-up dengan interval 1 detik dan 4 detik.Implementasi mode sleep/wake-up dengan interval 4 detik menghasilkan peningkatan lifetime 1 jam lebih lama dibanding dengan saat node sensor dalam kondisi selalu aktif dengan lifetime 5,5 jam. Penggunaan interval waktu 1 detik untuk sleep/wake-up pada node sensor tidak terlalu efektif digunakan karena lifetime yang dihasilkan cenderung sama jika dibandingkan dengan saat node sensor dalam kondisi selalu aktif. Pada daya baterai 362 mW, perangkat node sensor mencapai threshold-nya sehingga tidak dapat mengirim data secara nirkabel akibat satu atau lebih sub-sistem node sensor tersebut mati.]]>

<![CDATA[Absensi adalah suatu kegiatan pencatatan jumlah kehadiran pada suatu acara yang menghasilkan data kehadiran yang dapat digunakan untuk berbagai keperluan. Pada setiap kegiatan pasti dilakukan absensi kehadiran untuk mengetahui informasi peserta. Demikian juga dengan proses belajar mengajar di kampus dilakukan juga absensi. Kegunaan absensi ini adalah untuk mengetahui jumlah kehadiran mahasiswa/taruna untuk menentukan apakah mahasiswa/taruna tersebut bisa mengikuti ujian akhir semester dan untuk penambahan nilai. Sistem absensi yang dilakukan sampai saat ini di Program Diploma Pelayaran Universitas Hang Tuah masih menggunakan absensi manual dengan kertas yang menjadi satu dengan dokumen perkuliahan. Setiap perkuliahan akan dimulai Taruna mengambil dokumen perkuliahan di ruang Tata Usaha (TU) yang ditaruh dalam satu map. Absensi kehadiran wajib dilakukan oleh Taruna yang hadir dan tidak boleh diwakilkan. Apabila Taruna tidak bisa hadir menigkuti perkuliahan dikarenakan sakit, ijin dianggap masuk apabila disertai dengan surat dari dokter atau dari wali murid dan diketahui/diparaf oleh dosen pengampu mata kuliah pada saat perkuliiahan. Setelah selesai perkuliahan map perkuliahan dikembalikan lagi ke ruang TU. TU akan merekap semua absensi perkuliahan secara manual. Pengambilan data absensi yang dilakukan secara manual memiliki banyak kekurangan, seperti kecurangan Taruna dalam mengisi absensi, data yang tidak valid ketika data masuk salah, hilangnya atau rusaknya data yang ada, kurang efisiensi dan efektifitas pada pengolahan data. Pada penelitian ini penulis memanfaatkan teknologi sistem informasi untuk membuat absensi bagi Taruna di PDP dengan memanfaatkan salah satu fitur pada Google yaitu Google Form. Google Form atau yang disebut google formulir adalah alat yang berguna untuk membantu merencanakan acara, mengirim survei, memberikan mahasiswa atau orang lain kuis atau mengumpulkan informasi yang mudah dengan cara yang efisien. Form juga dihubungkan dengan spreadsheet, google form merupakan sebagai bagian dari Google Drive.]]>

<![CDATA[This study aims to analyze the causes of the decline in fresh water production on the Fresh Water Generator on the MV. Lumoso Karunia II. Researchers conducted this research for 12 months and 5 days conducted on the MV. Lumoso Karunia II which is a type of Bulk Carrier ship which is a ship owned by PT Lumoso Pratama Line Company. This research method uses quantitative methods. Researchers use secondary data in the form of library books, journals and documents related to this research, while primary data in this study is in the form of direct field studies. Data collection techniques in this study are library research, direct and indirect observation and interviews. The results of this study indicate that the performance of the fresh water generator auxiliary aircraft is less than optimal so that what is produced does not match the amount of capacity due to lack of maximum maintenance. With the thickness of scale attached to the evaporator pipe of 1.85 mm, it causes blockage of the evaporator pipe. Thus, there is a decrease in intake in the evaporator. So, the decrease in intake in the evaporator resulted in a decrease in fresh water production of 16 m3 tons in the fresh water generator. As a result of the decrease in fresh water production in the fresh water generator at MV. Lumoso Karunia II is a shortage of fresh water in accommodation and disruption of the cooling process in machinery.]]>

<![CDATA[Teaching and learning process is the core of the overall education process with the teacher as the main role holder. Many teaching and learning events are rooted in various views and concepts. Therefore the embodiment of the teaching and learning process can occur in various models. Teaching and learning process is a process of mutual interaction between instructors and students in educational situations to achieve certain goals. Learning methods carried out so far are still mostly done with theoretical teaching methods in class. The Ship Machinery Study Program has an Engine Simulator Laboratory that can be used as a learning medium for cadets, one of which is the Steam Boil course. To find out the level of understanding of the subject of the Steam boiler with theoretical learning methods in class with learning methods using the Engine Simulator, the Cadets were given a questionnaire containing the level of understanding with the 2 methods. From the results of the questionnaire obtained data, then the data is processed using statistical software. The data was tested using 2 methods namely the Normality Test and the T Test. Based on the results of the Kolmogorov-Smirnov Normality Test, values obtained before and after being treated were 0.053 and 0.20 because these values were greater than 0.05, so the data were normally distributed. While based on the T Test, the Sig (2-tailed) value is 0,000 < 0.05, so the decision that can be taken is to reject H0 or accept H1. So it can be concluded that there are significant differences in value before being treated using the Engine Simulator and after being treated using the Engine Simulator.]]>

<![CDATA[Attendance is an activity of recording the number of attendance at an event that produces attendance data that can be used for various purposes. In each activity attendance must be done to attend attendance information. Likewise, the teaching and learning process on campus is also carried out absenteeism. The purpose of this attendance is to find out the number of attendance of students / cadets to determine whether the student / cadets can take the final semester exams and to add grades. The attendance system that is carried out up to now in the Program Diploma Pelayaran Universitas Hang Tuah still uses manual paper attendance that is integrated with lecture documents. Every lecture will begin cadets takes lecture documents in the Administration Room which are put in one folder. Attendance must be done by cadets who are present and may not be represented. If a cadet is unable to attend following a lecture due to illness, permission is considered to be entered if accompanied by a letter from the doctor or from the student's guardian and is known / initialed by the lecturer in charge during the lecture. After finishing the lecture, the lecture map is returned to the administration room. Person of administrtion room will recapitulate all attendance lectures manually. Taking attendance data that is done manually has many shortcomings, such as cheating cadets in filling attendance, invalid data when data is entered incorrectly, loss or damage of existing data, lack of efficiency and effectiveness in data processing . In this study the authors utilize information system technology to create attendance for cadets in PDP by utilizing one of the features on Google, Google Form. Google Form or the so-called Google Form is a useful tool to help plan events, send surveys, give students or others quizzes or gather information easily in an efficient way. Forms are also linked to spreadsheets, Google forms are part of Google Drive.]]>
