Judul: The Effectiveness of Using Sawdust, Sea Sand, and Cocopeat as Filling Media in the Dry Transport System for Juvenile Sand Lobster (Panulirus homarus)
Abstrak: Lobster pasir (Panulirus homarus) merupakan salah satu komoditas unggulan dunia yang memiliki nilai ekonomis tinggi dan permintaannya terus meningkat sekitar 15% per tahun. Komoditas perikanan seperti udang dan lobster terus mengalami pergeseran seiring dengan permintaan konsumen, mulai dalam bentuk beku, kondisi segar, kemudian kondisi hidup. Transportasi sistem kering merupakan teknik yang tepat untuk mentransportasikan lobster agar tetap hidup hingga ke tangan konsumen. Pemilihan media pengisi kemasan dalam transportasi kering penting untuk diperhatikan. Penelitian dilakukan dengan tujuan menganalisis pengaruh penggunaan media pengisi berbeda terhadap kelangsungan hidup dan tingkat stres lobster pasir (Panulirus homarus) pada transportasi sistem kering. Transportasi dilakukan selama 12 jam, kemudian lobster dipelihara selama 14 hari. Penelitian ini menggunakan rancangan acak lengkap terdiri atas tiga perlakuan dan tiga ulangan. Perlakuan terdiri dari perlakuan media pengisi serbuk gergaji (M1), pasir laut (M2), dan serbuk sabut kelapa (M3). Transportasi dilakukan menggunakan kemasan berupa kotak styrofoam berukuran 47x32x29 cm. Perlakuan transportasi menggunakan lobster berukuran 90-100 g dengan kepadatan 10 ekor/kemasan. Hasil penelitian menunjukkan penggunaan media pengisi kemasan berbeda tidak berpengaruh nyata terhadap kelangsungan hidup lobster selama transportasi namun terdapat perbedaan terhadap kadar glukosa hemolim lobster pasca transportasi dengan nilai terbaik pada perlakuan media pengisi serbuk sabut kelapa sebesar 42,18±0,68 mg dL⁻¹. Penggunaan media pengisi serbuk sabut kelapa memiliki keuntungan ekonomi yang paling besar yaitu Rp 5.120.000,-. Berdasarkan penelitian ini, serbuk sabut kelapa dapat menjadi media pengisi alternatif selain serbuk gergaji dan pasir laut pada transportasi sistem kering juvenil lobster., Sand lobster (Panulirus homarus) is one of the world's leading commodities that has high economic value and its demand continues to increase by around 15% per year. Fishery commodities such as shrimp and lobster continue to shift in line with consumer demand, starting with frozen form, in fresh condition, and in live condition. Dry system transportation is the right technique for transporting live lobsters to consumers' hands. It is important to pay attention to the selection of packaging filling media in dry transportation. The research was conducted with the purpose of analyzing the effect of using different filling media on survival and stress levels of sand lobster (Panulirus homarus) in dry transportation systems. Transportation was carried out for 12 hours, then the lobster were reared for 14 days. This study used a completely randomized design consisting of three treatments and three replications. The treatments consisted of sawdust (M1), sea sand (M2), and cocopeat (M3) as fillers. Transportation is carried out using packaging in the form of a styrofoam box measuring 47x32x29 cm. The transportation treatment used lobsters measuring 90-100 g with a density of 10 fish/package. The results showed that the use of different packaging filling media had no significant effect on the survival of lobsters during transportation but there were differences in the glucose levels of the lobster hemolymph after transportation with the best value in the treatment of cocopeat filling media of 42.18 ± 0.68 mg dL⁻¹. The use of cocopeat filling medium has the greatest economic advantage, which is Rp. 5.120.000,-. Based on this research, cocopeat can be an alternative filling medium besides sawdust and sea sand in the dry system transportation
