Abstract

Human Resource Development becomes the key to change the better condition. One of components which influence its development is by mastering the international language. Indonesia as the archipelago country must be strong on maritime sector followed by potential human resource development. One of the ways which could be done is by improving the communication skill by using English Language. English has been introduced for learners since they are in the kindergarten. They have learned English for more than 12 years after they graduate in level of Senior High School. The research question in this study was how was the learners' view on English Learning to become young generation having good communication skill? This research aimed to know the learner's view by reflecting their prior experiences in English learning that had been done. This study conducted a descriptive quantitative by using survey to get the data. The instrument of the research referred to the skill of communication components reflected to the learners' experiences in English learning process since the long period of time. There were 30 learners delivering their ideas on English learning to answer the research question. The result showed that the learners had the obstacles dominantly in linguistics, social and culture, even psychological factors. It could be concluded that becoming a good communicator by using English, it needs the exploration on the learner's view in order to omit his or her obstacle in learning or acquiring English Language. It's really hoped that this research could give the discourse for English learners and teachers so young generation could have good communication skill by using English to support the maritime sector as the nations in archipelago country.

Abstract

Industri pelayaran rentan terhadap pencemaran laut berupa limbah minyak saat limbah cair dibuang dari kapal ke laut. Oleh karena itu diperlukan suatu alat yang digunakan untuk memisahkan air dan minyak, alat tersebut disebut OWS (Oil Water Separator). Penelitian ini melanjutkan penelitian sebelumnya tentang pengujian dan desain OWS untuk pemisahan air/minyak di kapal. Pada penelitian ini digunakan OWS untuk memisahkan air dan minyak pada 15ppm, jika kadar air kurang dari 15ppm maka dapat langsung dibuang ke laut. Pada penelitian ini dilakukan OWS dengan sensor kekeruhan yaitu mengklasifikasikan antara air dan oli dengan set point maksimum pada saat air kurang dari 25 NTU, dan sensor TDS digunakan untuk mengukur kadar ppm dalam air dengan set point. ini dapat melepaskan ke laut jika kurang dari 15ppm. Dan juga menggunakan komunikasi LoRa untuk mengirim data sensor dari pemancar ke penerima untuk komunikasi nirkabel. Sementara itu, metode pohon keputusan digunakan untuk mengklasifikasikan keluaran agar sesuai berdasarkan nilai-nilai sensor yang digunakan.

Abstract

Tambak Udang vaname merupakan tempat budidaya udang vaname, tambak ini sangat dibutuhkan pengaturan kualitas air tambak untuk meningkatkan kualitas hidup udang vaname. Pertumbuhan udang vaname sangat dipengaruhi oleh perubahan temperatur, kadar oksigen, kadar ph dalam air, dan juga kadar amonia. Bila terdapat standar yang tidak terpenuhi, akan memengaruhi kualitas hidup dari udang vaname itu sendiri. Berdasarkan permasalahan tersebut peneliti membuat alat monitoring kualitas air tambak udang vaname dengan kontrol paddle wheel berbasis mikrokontroller. Peneliti mengambil judul tersebut berdasarkan penelitian-penelitian terdahulu berupa prototype monitoring kualitas air berbasis IoT pada tambak udang vaname, sistem monitoring kualitas tambak udang vaname, dan prototype alat untuk mengukur pH, suhu, dan kadar kekeruhan air tambak budidaya udang vaname menggunakan arduino uno. Pada penelitian ini peneliti menggunakan sensor DO, sensor suhu DS18B20, RTC, sensor pH, dan sensor amonia sebagai monitoring kualitas air tambak udang vaname. Pengontrolnya menggunakan Arduino Mega 2560, yang dihubungkan dengan aktuator berupa lcd 20x4 dan led indikator sebagai monitoring alat, dan dilengkapi dengan metode fuzzy yang digunakan untuk mengatur putaran paddle wheel berdasarkan nilai pembacaan sensor DO dan sensor suhu DS18B20.

Abstract

Sistem distribusi kelistrikan merupakan salah satu faktor yang dibutuhkan dalam mentransmisikan sumber daya menuju beban agar dapat digunakan sesuai kebutuhan. Kualitas tenaga listrik yang baik akan menghasilkan produksi daya yang diberikan ke beban bisa maksimal. Analisa sistem saluran dilakukan untuk mngetahui besar dan sudut fasa tegangan pada setiap saluran (bus), daya nyata dan daya reaktif yang ada pada setiap saluran. Hasil analisis aliran daya dapat digunkan untuk menentukan jumlah kerugian (daya dan rugi tegangan), sehingga dapat dilakukan optimasi dengan penambahan komponen kelistrikan untuk mengtasi adanya rugi tegangan pada sistem saluran. Dengan menjaga sistem aliran daya yang ada maka daya yang diberikan ke beban akan maksimal. Hal ini akan mengoptimalkan proses produksi yang ada di industri.

Abstract

Siang Vocational School in Surabaya is required to equip its students with the latest skills in sensor and actuator technology. One important competency is the ability to use and analyze data from sensors and actuators to diagnose and repair control systems. This training program is designed to develop these skills in class XII students. The objectives of this training include improving students' ability to use sensors and actuators, being able to analyze data from inspections of sensors and actuators, making improvements based on sensor and actuator data. Training methods include providing modules on sensor and actuator technology, discussions, slide presentations on sensor and actuator technology, practical use and analysis of sensors and actuators. The expected results are that students are able to use sensors and actuators skillfully, are able to diagnose damage to sensors and actuators correctly, carry out repairs effectively based on sensor and actuator data. The benefits of this training are increasing the competitiveness of graduates of SMK Siang Surabaya in the world of work, preparing students to face the latest technological developments in the sensor and actuator industry, building students' self-confidence in handling problems on motorbikes. This training program is an important step in preparing students of SMK Siang Surabaya to become a competent sensor and actuator technician and ready to face future industrial challenges.
