Research on cutlassfish’s diet has been carried out in several areas, but similar research does not exist or still rarely found in Gunungkidul. The aim of this study is to determine the overall composition of the cutlassfish's food, the most dominant type of food and cutlassfish's growth pattern. Methods including random sampling in the field, measurement of length and weight and identification of food types using stomach analysis method and proximate analysis on both cutlassfish’s muscle and diet. The results of the study then analyzed using the formula by Walpole (1992), length-weight relationship formula according to Le Cren (1951) followed by determining the value of b with the t-test at confidence interval of 96% and condition factor. Food composition and preferences were calculated using numerical and volumetric methods to find the IP (Index of Preponderance) and IRI (Index Relative Importance) values. Composition based on types of food is dominated by fish at 89% with Engraulidae as the main group with total percentage of IP 45.58 and IRI 76.47, respectively. Proximate analysis values indicate low levels of protein (with highest value of 23.82%) and high-moisture content (with highest value of 71.98%) caused by cold temperatures during storage. The regression showed that cutlassfish have an allometric positive growth pattern. The results revealed that the food is sufficient for the growth of cutlassfish (Trichiurus lepturus).

Given the large market opportunity for ginger to meet consumption, it is necessary to seek various methods of increasing production, both in terms of quality and quantity. To achieve these result, ginger production in Indonesia must be expanded, intensified, and diversified in an appropriate and economically sustainable manner. The goal of this study was to see how spacing and bokashi from various organic fertilizers affected the growth and yield of elephant ginger. This experiment used a factorial design with a randomized block design (RBD) of two factors. The first factor is the spacing (J), which has three levels: 40 cm x 20 cm spacing (J1), 40 cm x 30 cm spacing (J2), and 40 cm x 40 cm spacing (J3). The second factor is organic fertilizer bokashi (B), which is made up of four experiments: no bokashi (Bt), pig manure bokashi (Bb), cow dung bokashi (Bs), and green manure bokashi (Bh). The experimental results were statistically analyzed using analysis of variance. Results showed that the interaction effect of distances and the type of bokashi with organic fertilizer has no significant difference (P 0.05) in the growth and yield of elephant ginger. The average net assimilation rate 90-105 dap, as well as the average plant growth rate 75-90 dap were compared. The highest yield of fresh rhizomes per hectare was obtained in the at a 40 cm x 20 cm spacing.
