Abstract

Pemantauan kepatuhan penggunaan Alat Pelindung Diri (APD) merupakan aspek krusial dalam Keselamatan dan Kesehatan Kerja (K3) di lingkungan industri. Namun, pengawasan manual memiliki keterbatasan dalam hal konsistensi dan cakupan area. Pendekatan otomatisasi menggunakan computer vision sering kali terkendala dalam mendeteksi objek APD berukuran kecil, sesuai dengan standar pada MS COCO yaitu untuk objek yang ukurannya <322 piksel terhadap keseluruhan input gambar, yang kerap kehilangan detail spasial akibat proses downsampling pada jaringan saraf tiruan. Penelitian ini bertujuan mengatasi permasalahan tersebut dengan memodifikasi arsitektur YOLOv11n-seg melalui integrasi mekanisme Coordinate Attention (CA) pada modul Neck. Pendekatan ini dirancang untuk memperkuat representasi fitur spasial dan kanal tanpa membebani komputasi secara berlebihan. Model dilatih dan dievaluasi menggunakan dataset industri migas yang terdiri dari 1.551 citra dengan 14 kelas objek. Hasil pengujian menunjukkan bahwa model modifikasi mampu mencapai Mean Average Precision (mAP@50) sebesar 71,3%. Integrasi CA terbukti efektif meningkatkan akurasi pada objek kecil yang dinamis dan rentan oklusi, dengan peningkatan mAP@50 pada kelas Hand Gloves sebesar 8,2%, Safety Glasses sebesar 2,3%, dan Dust Mask sebesar 2,2% dibandingkan model baseline. Selain itu, model mampu beroperasi secara real-time dengan kecepatan inferensi 210,5 FPS. Penelitian ini menyimpulkan bahwa modifikasi Neck dengan Coordinate Attention dapat meningkatkan sensitivitas deteksi objek kecil pada sistem pengawasan K3 tanpa mengorbankan efisiensi waktu nyata.

Abstract

Tanaman padi sangat penting bagi umat manusia. Penyakit tidak dapat dihindari dalam pertanian padi, tetapi pengelolaan yang tidak tepat dapat menurunkan hasil panen. Berdasarkan hal tersebut, penelitian ini merancang sebuah program untuk membantu petani mengidentifikasi penyakit tanaman padi. Layanan obrolan berbasis bot bernama Telegram menampilkan temuan identifikasi. Identifikasi menggunakan pengetahuan petani sebagai data pelatihan. Beberapa gejala yang dimasukkan pengguna digunakan sebagai data uji untuk identifikasi. Dataset akan diklasifikasikan menggunakan Naive Bayes. Bot akan menampilkannya di Telegram. Membuat bot API Telegram adalah langkah pertama dalam sistem ini. Selanjutnya, pendekatan Naive Bayes menghitung prior, likelihood, dan posterior dan mengevaluasinya menggunakan matriks kebingungan. Pengujian menggunakan input dari banyak pengguna menghasilkan nilai presisi 90% untuk semua kelas, nilai recall 85%, dan f1-score 84%. Sementara itu, akurasinya adalah 85%.

Abstract

Small-scale shrimp fisheries in Kotabaru Regency, South Kalimantan, not only serve as a vital source of local economic support but also pose potential threats to the sustainability of non-target species caught as bycatch, including the mangrove horseshoe crab (Carcinoscorpius rotundicauda), which is protected in Indonesia. This study aimed to assess the stock status of Carcinoscorpius rotundicauda captured as bycatch in local shrimp fisheries. Data was collected from January to March 2025, with a total of 125 individuals. Results indicated that Carcinoscorpius rotundicauda exhibited a negative allometric growth pattern. The length at first capture ( ) was found to be lower than the length at first maturity ( ). Specifically, was 11.85 cm for trammel nets and 13.52 cm for crab gillnets, while  was 17.59 cm, suggesting that most individuals caught as bycatch had not yet reached gonadal maturity. This condition reflects fishing pressure on the population. Using the Length-Based Spawning Potential Ratio (LB-SPR) method to assess stock status of mangrove horseshoe crab that indicating overexploited (SPR<20). These findings highlight the urgent need for sustainable fisheries management, including regulations on fishing gear and protection measures for bycatch species such as Carcinoscorpius rotundicauda in Kotabaru waters.

Abstract

Pelagic fish resources have a very important role in regional economic development. The assumption that fish resources are common property so that everyone is free to catch (open access) is a problem with overfishing in East Java waters. The purpose of this study is to determine the superior commodity of small pelagic fish, the status of exploitation of superior  fish resources and to compile a scenario of sustainable management of superior resources. The method in this research is quantitative descriptive method with data analysis used including Location Quotient (LQ), Schaefer (1954), Fox (1970), Walter Hilborn, and programming STELLA (System Thinking, Experimental Learning Laboratory with Animation). The research result of the superior species in the province in the south of East Java) is sardin, while the superior fish in the regency is s Rainbow runner. The status of fisheries at the level of superior fisheries exploitation in South East Java, the level of exploitation of ssrdin fish is 240% with the status of Depleted. Finally, the level of exploitation for s Rainbow runner fish is 689%, which means that they are included in depleted. The scenario of sustainable management of pelagic fisheries for the next 10 years, namely 2018 - 2027 for lemuru fish, the highest biomass reserves will be obtained in 2027, using a fixed effort allocation which has biomass reserves of 179% and the potential value of sustainable reserves of 8,438.48 tonnes. The results showed that the superior commodities of small pelagic fish in North East Java were mackerel fish. The superior fish commodity in the Regency / City is obtained by Finny scad fish. The level of exploitation for mackerel is 127% with the status of Over Exploited, and the level of exploitation for Finny scad is 131% with the status of Over Exploited. The scenario for the management of the superior mackerel commodity, the highest biomass reserve in 2027 is the allowable fishing effort allocation (fJTB) of 129%.
