Abstract

Problems in operating trap fish tool are that fishermen do not know the actual condition of the traps. Thus, it causes the effectiveness of time and number of catches to be not optimal. Based on the conditions and problems above, the writer concluded that an innovation in the operation of the trap to design a magnetic sensor-based system/tool to detect lobster catches that can be accessed via smartphone is required. The aim of this study is to design and observe the performance of using a magnetic sensor to detect lobsters' (Panulirus spp.) movements on a laboratory scale (in the aquarium). Data analysis in this study used the Confusion Matrix method, where this method divides the test results into 4 common conditions: TP (True Positive), TN (True Negative), FP (False Positive), and FN (False Negative). From the 4 conditions, Recall, Specificity, Precision, Accuracy, and F1 Score can be calculated. From 16 tests with the 16 lobsters of 60-190 grams/individual, it obtained conditions of TP of 25 times, TN of 109 times, FP of 11 times, and FN of 15 times. From the four conditions, it was obtained a Recall value of 0.625 or 62.50%, Specificity of 0.9083 or 90.83%, Precision of 0.6944 or 69.44%, Accuracy of 0.8375 or 83.75%, and F1 Score of 0.6579 or 65.79%. Based on the observations and test results of the actual detection and application system in this study, performance reference for using magnetic sensors was by using Accuracy with a score of 83.75%.

Abstract

The Fisheries Management Republik Indonesia (WPP-RI) 573 encompasses strategic waters in the southern Indian Ocean of Indonesia, playing a critical role in global ocean circulation through the Indonesian Throughflow (ITF). This study aims to examine the physical oceanographic characteristics, particularly sea surface temperature (SST), salinity, and marine ecosystem productivity in WPP 573, as well as the impacts of ITF variability on these parameters. Data utilized include SST, salinity, and current velocity obtained from satellite observations and numerical models. The analysis reveals that the ITF transports tropical water masses from the Pacific Ocean to the Indian Ocean, significantly influencing the spatial and temporal distribution of temperature and salinity in the region.

Abstract

The Southern Java Sea is vital for sustaining marine ecosystems and fisheries productivity, shaped by dynamic oceanographic processes. This research investigates the relationship between chlorophyll-a distribution, sea surface temperature (SST) patterns, and the spatial dynamics of fishing grounds in the area. Using satellite-based data from Aqua-MODIS and numerical model outputs, chlorophyll-a levels and SST variability were analyzed on 2024. Descriptive statistics and spatial analysis were applied to identify temporal trends and their connection to productive fishing zones. The results indicate a strong correlation between chlorophyll-a distribution and SST patterns, with seasonal changes significantly influencing fishing ground productivity. These findings provide critical insights for advancing sustainable fisheries management and resource planning in the Southern Java Sea. The study emphasizes the need to incorporate oceanographic indicators into fisheries policies to promote ecosystem health and economic resilience.

Abstract

The sprinkler irrigation system of horticultural agriculture at Universitas Samudra is able to increase the efficiency of water use when the climate change phenomenon hits. However, sprinkler irrigation requires quite high operational investment costs. The purpose of the planning is to obtain the design of the sprinkler irrigation network and optimize the operational investment costs of irrigation. The method used is hydraulic simulation of irrigation using variations in centrifugal and submersible transfer pump power and PVC pipe size. Furthermore, the results of the irrigation simulation were analyzed using the Taguchi method. The planning results show that the sprinkler irrigation network covers an area of 7,500 with an elevation of 6-8 meters above sea level. The water requirement for 53 sprinklers is 8.48 liters/second, and the total water requirement for horticultural plants is 2,063.2 per season. The use of a combination that can optimize the operational investment costs of irrigation is the use of centrifugal transfer pump power (0.6 kW), submersible transfer pump power (0.6 kW), and PVC pipe sizes of 1/2, 1, 1 1/2, and 2 inches. This combination produces an optimum water pressure prediction of 1.756 bars and produces an optimum electricity usage cost prediction per day of Rp. 30,350. By using centrifugal transfer pump power, submersible and low-capacity PVC pipe size makes it more cost-efficient compared to other combinations.

Abstract

Teknologi Unmanned Surface Vehicle (USV) sesungguhnya telah berkembang, akan tetapi mendesain dan membuat suatu USV yang mudah untuk diikuti menjadi penting. Berdasarkan hal tersebut, penelitian ini bertujuan menghasilkan rancang bangun wahana USV dengan tipe katamaran dan berbahan dasar fiberglass yang ringan. Sistem kendali wahana USV menggunakan wireless remote control 2,4 Ghz. Wahana USV yang telah berhasil didesain dan dibangun, selanjutnya dilakukan pengujian untuk melihat kemampuan kecepatan dan manuvernya. Berdasarkan hasil pengujian yang dilakukan, diperoleh wahana USV mampu bergerak lurus dengan kecepatan rata-rata 1,3 m/s, dan berputar 360° dengan kecepatan rata-rata 1,03 m/s dan 1,07 m/s. Wahana USV yang dihasilkan masih memerlukan beberapa perbaikan pada pengatur kecepatan, sehingga di masa yang akan datang dapat digunakan dalam aktivitas survei baik itu di danau atau di perairan pesisir.Unmanned Surface Vehicle (USV) technology has actually developed, but designing and making a USV that is easy to be followed is important. Based on this case, this research aims to design a USV with a catamaran type and made from lightweight fiberglass. The USV control system uses a 2.4 Ghz wireless remote control. USV vehicles that have been successfully designed and built are then tested to see their speed and maneuverability. Based on the test results, the USV vehicle was able to move straight with an average speed of 1.3 m/s, and rotate 360° with an average speed of 1.03 m.s and 1.07 m/s. The result of the USV vehicle still needs some improvements to the speed regulator, so that in the future it can be used in survey activities either in lakes or in coastal waters.

Abstract

Bawang merah (Allium ascalonicum L.) merupakan komoditas hortikultura strategis yang produktivitasnya sangat dipengaruhi oleh kesesuaian varietas dengan kondisi lingkungan. Lahan kering dataran rendah memiliki potensi pengembangan, namun menghadapi kendala suhu tinggi dan ketersediaan air terbatas. Penelitian ini bertujuan mengevaluasi pertumbuhan dan hasil tujuh varietas bawang merah asal Jawa Timur pada kondisi lahan kering dataran rendah. Penelitian dilaksanakan di lahan percobaan Fakultas Pertanian Universitas Muhammadiyah Jember pada Maret–Juni 2024 dengan menggunakan Rancangan Acak Kelompok (RAK) satu faktor, terdiri dari tujuh varietas dan tiga ulangan. Parameter yang diamati meliputi tinggi tanaman, panjang daun, jumlah daun, diameter umbi, jumlah umbi per rumpun, bobot kering umbi, dan umur panen. Hasil penelitian menunjukkan adanya variasi nyata antar varietas. Rubaru (V3) dan Manjung (V4) unggul pada pertumbuhan vegetatif, sedangkan Superphilip (V5) dan Batu Ijo (V7) menghasilkan diameter dan bobot umbi lebih besar. Rubaru (V3) dan Biru Lancor (V6) menghasilkan jumlah umbi lebih banyak per rumpun, sementara Bauji (V1) dan Manjung (V4) memiliki umur panen lebih singkat. Kesimpulannya, pemilihan varietas bawang merah di lahan kering dataran rendah perlu disesuaikan dengan tujuan budidaya, baik untuk produktivitas tinggi per umbi, jumlah umbi lebih banyak, maupun panen lebih cepat
