Abstract

Kegiatan pengabdian masyarakat ini bertujuan untuk memberikan bantuan kepada petani rumput laut di Desa Tesabela, Kupang Barat, Kab. Kupang. Bantuan yang diberikan meliputi pembuatan konstruksi pengering para-para, melakukan penyuluhan cara penggunaannya, dan memberikan sosialisasi terkait peningkatan produktivitas dan kualitas rumput laut pasca panen. Pengering para-para mampu memberikan penjemuran rumput laut yang lebih bersih, karena rumput laut tidak diletakkan secara langsung di atas permukaan tanah. Selain itu air akan lebih mudah turun ke bawah karena menggunakan alas yang terbuat dari waring. Sehingga rumput laut hasil pengeringan memiliki kualitas yang lebih baik dan tidak berjamur. Hasil kegiatan ini memberikan pemahaman masyarakat bagaimana cara membuat pengering para-para dan cara penggunaannya secara mandiri, serta bagaimana cara meningkatkan produktivitas rumput laut serta peningkatan kualitas rumput laut pasca panen.

Abstract

Pengoperasian kapal dapat berjalan dengan lancar didukung oleh mesin-mesin yang handal dan dapat berjalan dengan efektif dan efisien. Kapal Putra Makmur 86 merupakan salah satu kapal ikan yang dimiliki oleh PT. Matsyaraja Arnawa Satambhapura dan beroperasi di Nusa Tenggara Timur. Kapal ini mempergunakan bahan bakar solar untuk mendukung kinerja mesin-mesinnya. Pentingnya kebutuhan bahan bakar pada mesin kapal dan masih kurangnya informasi tentang kinerja dari mesin-mesin di kapal tersebut, maka dalam tulisan ini dicoba bertujuan untuk menganalisis penggunaan bahan bakar dan kinerja mesin induk dan generator pada Kapal Putra Makmur 86 selama beroperasi. Metode observasi, wawancara, analisis perhitungan bahan bakar dan uji frekuensi dipergunakan dalam penelitian ini. Berdasarkan hasil kegiatan operasi selama 32 hari penggunaan bahan bakar pada Kapal Putra Makmur 86 selama beroperasi sangat efektif dan efisien. Penghematan penggunaan bahan bakar solar dapat dicapai sebanyak 5,90% (0,47 Ton). Hal ini dapat dilihat dari perbedaan dari hasil pengamatan secara langsung dan perhitungan konsumsi bahan bakar. Hasil perhitungan didapatkan rata-rata 3,99±1,47, dengan standar error 1,04, dan rentang penggunaan dari 2,95-5,02 Ton. Sedangkan, hasil pengamatan didapatkan rata-rata 3,75±0,35, dengan standar error 0,25, dan rentang penggunaan dari 3,5-4 Ton. Penyebab dari perbedaan ini adalah pengaruh cuaca dan arus yang baik selama beroperasi, rute pelayaran, kondisi mesin yang masih bagus, muatan, dan gaya mengemudi yang baik sehingga menyebabkan konsumsi bahan bakar tidak terlalu banyak dibandingkan dengan hasil perhitungan.The vessel's operation can run smoothly supported by reliable machines and can run effectively and efficiently. Putra Makmur 86 vessel is one of the fishing vessels owned by PT. Matsyaraja Arnawa Satambhapura and operates in East Nusa Tenggara. This ship uses diesel fuel to support the performance of its engines. The importance of the need for fuel on the ship's engine and the lack of information about the performance of the engines on the ship, so in this paper, an attempt is made to analyze the use of fuel and the performance of the main engine and generator during operation. The methods of observation, interviews, analysis of fuel calculations, and frequency tests were used in this study. Based on the results of operating activities for 32 days, the use of fuel on the Putra Makmur 86 vessel was very effective and efficient. Using diesel fuel can be saved as much as 5.90% (0.47 Tons). This can be seen from the difference between direct observation and calculation of fuel consumption. The calculation results obtained an average of 3.99±1.47, with a standard error of 1.04, and a usage range of 2.95–5.02 Ton. Meanwhile, the observation results got an average of 3.75± 0.35, with a standard error of 0.25, and a range of use from 3.5-4 Ton. The cause of this difference is the influence of good weather and currents during operation, shipping routes, good engine condition, payload, and good driving style so that fuel consumption is not too much compared to the calculation results.
