The success of cultivation is derermined by good quality feed, especially in the hatchery phase. Good feed is high-quality feed so that it can provide nutrients in an amount that is in accordance with the needs of the larvae. The natural ffod commonly used is silk worms (Tubifex sp). This study aims to determine the effect of using organic waste on the growth of silkworms (Tubifex sp). this study used an experimental method with a completely randomized design (CRD) model with test variables in the form of differences in feed doses including 0 g,5 g,10g and 15 g which were given for 21 days. The feed given was fermented with a composition of 20% saw waste 20%, tofu dregs 20% sugarcane molasses bran 10% and EM4 10%. The results showed that treatment D (15 g/container) had the highest average absolute biomass growth of 61.02±12,86 g/m2 with a poplation of 106.6±97.3 ind/m2. The resuls showed that treatment D had a very significant effect (p0.05) on the growth of silk worms (Tubifex sp), indicating that the average growth rate to treatment was significant.

This study takes the title Impact of Covid-19 on Indonesia’s Economic Growth. The purpose of this study was to determine the effect of partial and simultaneous as well as the spatial pattern of cases exposed, died and recovered on Indonesia’s economic growth. This research uses a quantitative approach with the method of documentation and literature study. The sampling method used is non-probability sampling with census sampling collection techniques. The sample in this study was 34 provinces in indonesia with a total sample of 68. The analytical tools used were multiple linear regression and klassen typology. The results of the multiple linear regression t-test (partial), F-test (simultaneous) and R2 test showed that the variables of cases exposed, recovered and died had a negative and insignificant effect on Indonesia’s economic growth seen from the constant value of 1,395, X1 coefficient 0,4, coefficient X2 0,1, and coefficient X3 0 and R2 test of -11,9%. Then the results of the klassen typology show the spatial pattern of the highest number of exposed cases in western and central Indonesia, namely the provinces of East Kalimantan and Bali, Riau, North sumatera, West Java, Central Java, and East Java. Then the highest number of deaths was in every part of Indonesia, both the western, central and eastern parts of the provinces of Bengkulu, Jambi, Kaltara, NTB, North Sulawesi, Southeast Sulawesi, Maluku, West Papua, West Sulawesi and Gorontalo. Finally, the highest number of recovered cases was in every part of Indonesia including the provinces of Aceh, Bengkulu, Jambi, Central Kalimantan, South Kalimantan, Kaltara, Riau Islands, NTB, South Sumatera, West Sumatera, North Sumatera, North Sulawesi, Southeast Sulawesi, Central Sulawesi, Lampung, Riau, North Maluku, Maluku, West Papua, Papua, West Sulawesi, NTT and Gorontalo.
