Rumput laut (eucheuma cottonii) merupakan tumbuhan yang tergolong dalam ganggang (alga) multiseluler divisi thallophyta. untuk dapat meningkatkan produksi rumput laut harus dilakukan optimalisasi penggunaan faktor produksi suatu penggunaan faktor produksi bensin, tali benang, tali botol, upah, bibit, pelampung, tenaga kerja. kelurahan mamburungan dan kelurahan pantai amal kecamatan tarakan timur menjadi salah satu daerah yang banyak memproduksi hasil rumput laut. penelitian ini bertujuan untuk mengetahui (1) karakteristik petani rumput laut di tarakan timur; (2) pendapatan usahatani rumput laut di tarakan timur, (3) efisiensi teknis pada usahatani rumput laut di tarakan timur. metode penentuan sampel purposive sampling dengan responden 86 petani. analisis yang digunakan dalam penelitian ini adalah analisis deskriptif kuantitatif, analisis biaya dan analisis regresi liner berganda dengan bantuan aplikasi microsoft excel dan spss 24. hasil analisis menunjukkan bahwa karakteristik usaha rumput laut di kecamatan tarakan timur kota tarakan meliputi umur, pendidikan, tingkat status, pengalaman; rata-rata pendapatan petani rumput laut di kecamatan tarakan timur kota tarakan sebesar rp. 3,413,994 / produksi; berdasarkan hasil uji t diperoleh bahwa variabel bensin (x1) (sig 0.001), dan pelampung (x2) (sig 0.000) berpengaruh terhadap pendapatan sedangkan variabel tali benang (x2) (sig 0.810), tali botol (x3) (sig 0.134), upah (x4) (sig 0.707), bibit (x5) (sig 0.725), dan tenaga kerja (x7) (sig 0.406) tidak berpengaruh. variabel independen yang paling berpengaruh. berdasarkan hasil uji efisiensi faktor produksi melalui fungsi produksi cobb-douglas diketahui nilai efisiensi faktor produksi bensin, tali benang, tali botol, upah, bibit, pelampung dan tenaga kerja tidak efisien karena nilainya kurang dari 1 yang artinya perlu pengurangan faktor produksi dari masing-masing variabel. kata kunci: efisiensi, pendapatan, produksi, rumput laut

The plant known as seaweed, or eucheuma cottonii, is a member of the thallophyta's division of multicellular algae. optimizing the use of production factors, i.e., the use of production elements like fuel, rope, bottle rope, wages, seeds, buoys, and manpower, is necessary in order to enhance seaweed output. two of the places in the east tarakan district that generate a lot of seaweed are mamunjungan village and pantai amal village. the objectives of this study were to ascertain (1) the traits of seaweed farmers in east tarakan, (2) the amount of money made from seaweed farming there, and (3) the technical effectiveness of seaweed farming there. purposive sampling was used to determine the sample, and 86 farmers participated in the survey. with the use of microsoft excel and spss 24, quantitative descriptive analysis, cost analysis, and multiple linear regression analysis were performed for this study. the results of the analysis showed that the characteristics of seaweed businesses in east tarakan district, tarakan city included age, education, status level, experience; the average income of seaweed farmers in east tarakan district, tarakan city was idr. 3,413,994 / production; based on the results of the t test, it was found that the variables petrol (x1) (sig 0.001), and buoy (x2) (sig 0.000) had an effect on income while the variables rope (x2) (sig 0.810), bottle rope (x3) (sig 0.134), wages (x4) (sig 0.707), seeds (x5) (sig 0.725), and labour (x7) (sig 0.406) had no effect. the most significant independent variable, as determined by the cobb-douglas production function and the results of the production factor efficiency test, was that each variable's production factors must be reduced because the efficiency values of labour, gasoline, rope, bottle rope, wages, seeds, floats, and wages were all less than 1. keywords: efficiency, income, production, seaweed
