Mealworm is the larva stage of Tenebrio molitor L. beetle which is used for pet feed. The aim of this research was to analyze the effect of feeding medias to support the growth of mealworm. The compared feeding media were 100% dry tofu by product as a control, 100% rice bran, 100% rice husk, 50% dry tofu by product + 50% rice bran, 50% dry tofu by product + 50% rice husk and 50% rice husk + 50% rice bran. Randomized Complete Design was used as the experimental design with 6 treatments with 3 replications for each treatment. The result showed that body weight and body length were not significantly different (P>0.05) among media, but mortality and pupation were significantly different (P<0.05). The feeding media with 50% dry tofu by product + 50% rice bran are better to use because it can increase feed consumption, percentage of pupation, and reduce mortality.
Silkworm is a cold-blooded animal (poikiloterm) so that environment conditions greatly affect their growth. In China, silkworms rearing in the highlands with cool conditions. However, Indonesia is a tropical country with diverse topography conditions and some of them are low altitude areas below 250 m above sea level (asl). This study examined the productivity of silkworms in altitude of 250 m asl. The material used silkworm seedlings from the Silkworm Breeding Center (PPUS) Soppeng and Candiroto, and using 2 different types of mulberry leaf feed (Morus multicaulis and Morus cathayana). Both PPUS have different climatic and altitude conditions. Soppeng at an altitude less than 300 meters asl and Candiroto at a higher one. The results showed that silkworm from Soppeng with fed M. multicaulis was significant different (P<0.05) than other treatments in almost all parameters (consumption, weight of larva, quantity and quality of cocoon shell). The result indicated silkworm Soppeng breed with M. multicaulis have good performance either cocoon shell productions and qualities in Tropic (especially rearing at altitudes around 250 m asl).
Abstract:Cricket is widely recognized in Indonesia especially in Java island, and commonly kept by village farmers for food and feed. In general, crickets has very short life cycle (60-70 d), with three weeks of laying period and egg production within the range of 200-1,500 eggs/female. The female has capability for multiple mating with several males and therefore produces more fertile eggs. Serial studies including experiments on laboratory and field observation of local crickets had been conducted to evaluate the farming practices and reproductive performance of three local species (Gryllus spp., Gryllus mitratus and Gryllus testaceus) which were given local feeds-Manihot esculenta and Carica papaya leaves. The experiment was conducted in randomized block design with feed as the treatments and species as the block. Cliring crickets (G. mitratus) fed with M. esculenta leaves revealed the highest total egg production (1,478.22 eggs), with daily egg production of 32.85 eggs/d, the longest laying period (45 d), the lowest feed intake (0.28 g/head) and feed conversion (0.93 mg/egg), compared to Cendawang crickets (G. testaceus) and Gryllus spp.. The revenue and cost (R/C) ratio was 1.4, indicating that small scale cricket enterprise could offer significant profit and could be chosen as an alternative activities for earning regular income.
Attacus atlas is one of the wild silkworms which is originated from Indonesia, which has economic value and high potency to be developed especially at the cocoon stage. These potential aspects for future developed include row material of silk fabrics, cosmetics, medical, and engineering materials. However, this potential has not been matched by productions level. Attacus atlas still live in nature with only 10% of cocoon production rate. In this study, A. atlas was reared in the laboratory to determine the different characteristics of Attacus atlas cocoon between rearing enviromntment as compared to which in nature. The results showed that the characteristics of the cocoon varies and influenced by humidity and temperature environments, place and behavior during making cocoon. Whole cocoon weight average of 6.37±1.07 g/cocoon, weight of floss (0.23±0.09 g/cocoon or 5.82±3.86%), weight of shell cocoon (0.62±0.35 g/cocoon or 11.
Environmental pollution can be minimized by utilizing traditional market waste through the cultivation of earthworms. Market waste that is commonly found is vegetable and fruit waste. Market waste that is used as feed can minimize the production budget in worm farming. This research used a completely randomized method, four treatments and three replications. The aim of this study was to investigate the effect of feed with mustard green waste and papaya waste on the productivities (body weight and body length) of Lumbricus rubellus, vermicompost production, and that economic value. The results of the study stated that the treatment significantly (P<0.05) affected the parameters of worm body weight, worm body length, and vermicompost production. Papaya waste (P400) treatment produce the highest body weight of L. rubellus in 1.108 ± 0.128 g, body length in 9.367 ± 0.446 cm, and waste degradation in 45.62 %. The papaya waste showed the highest results in terms of body weight gain and body length of L. rubellus. The cultivation of earthworm can provide economic value for Rp 514.428,60/4 months by producing earthworms and vermicompost.
