Abstract

Earthworms are one of the animals used as indicators to assess soil quality and fertility. In earthworm cultivation, several factors affect the life of earthworms, including temperature, pH, moisture, nutrient content, and media texture. This study aims to evaluate the productivity of earthworms (Lumbricus rubellus) in a mixed medium of cow manure and cricket manure. The method used in this study is a Completely Randomized Design (CRD) with 6 treatments and 3 replications, along with a Tukey posthoc test. The results showed that the addition of cricket manure to cow manure as a cultivation medium could increase earthworm productivity. The use of 90% cow manure with the addition of 10% cricket manure resulted in an average weight increase of 17 g, an average of 94 cocoons, and an average media reduction of 260.50 g. The addition of more than 10% cricket manure to cow manure could reduce earthworm productivity.

Abstract

Crickets are a promising alternative source of animal protein due to their high levels of amino acids, fatty acids, and protein (61.58%). These nutrients have applications in the pharmaceutical industry, human food, bird feed, and as a substitute for livestock feed, particularly in the form of cricket flour. The Kalung cricket (Gryllus bimaculatus) is notable for its rapid growth rate and efficient feed conversion. This study aimed to evaluate the effects of diets combining concentrate with cassava leaves of different maturities on the performance of Kalung crickets (Gryllus bimaculatus). A completely randomized design (CRD) was employed, consisting of three treatments with five replications each. The treatments were R1= concentrate+young cassava leaves, R2= concentrate+mature cassava leaves, R3= concentrate+cassava leaf stems, with a combination ratio of 1:1.5. The parameters observed include feed consumption, body weight gain, egg production, feed conversion, mortality, and income over feed cost (IOFC). The results showed that no significant differences among treatments in feed intake, weight gain, and mortality. However, significant differences were observed in egg production (0.022±0.011 g/individu/day) and feed conversion (1,88±0.95) with the R1 treatment showing the most favorable results. A diet combining concentrate with young cassava leaves significantly improves the reproductive performance and feed efficiency of Kalung crickets. This combination is recommended for enhancing productivity in Gryllus bimaculatus farming systems.
