Abstract

Domestic waste contains good organic matter for plant growth. One of the domestic wastes owned by each house is rice washing water. In addition, the tofu industry is also widely found in Indonesia, one of which is Cilacap City. The content of organic matter possessed by the two wastes is a source of plants. To reduce the environment, this waste can be used as raw material for making liquid organic fertilizer (POC). In addition to being environmentally friendly, the raw materials used are also easy to find. This study aims to analyze pH, temperature and levels of C-Organic in liquid organic fertilizer from tofu industrial waste and rice washing water. The manufacture of liquid fertilizer is carried out using the anaerobic method, which utilizes bacteria that are active without oxygen through a fermentation process for 14 days. To determine the effect of adding EM4 and molasses, compositional variations were carried out on samples of liquid fertilizer, namely KO, P1, P2, and P3 with molasses volume sequentially 0 grams, 5 grams, 5 grams, 10 grams. Meanwhile, the volume of EM4 added sequentially is 0%, 5%, 10% and 5%. Measurements of pH and temperature were carried out every 4 days, but measurements of C-Organic were carried out at the beginning and end of the mini-research. The final pH of POC was in accordance with quality standards with KO = 4.5 and P1, P2 and P3 = 4. The final temperature of KO samples was 29.5ᵒC, P1 29ᵒC, P2 and P3 28.5ᵒC. The highest organic-C content was owned by the knockout sample, which was 0.00297. All samples in this mini research are not included in liquid organic fertilizer (POC) but can be classified as nutrients for soil improvement.

Abstract

Heavy metals produced by the industrial sector in Cilacap will contaminate the waters and impact the organisms in them, which will affect the condition of humans as consumers. The purpose of the importance of this research activity is to compare the type of fish and the value of heavy metal Pb with the quality standards of the Ministry of Environment No.51 of 2004, BPOM Regulation 2009 and SNI 7387 of 2009, as well as knowing the maximum consumption limit of consumption fish catches to control the pattern eat fish indicated heavy metals. The method used is a comparative description with survey techniques in 3 locations where fish auctions (FAM) and Pb level analysis using the AAS method. The types of fish with the highest level of consumption in Cilacap are kembung, tuna and tongkol. The Pb level of kembung, tuna and tongkol passes the threshold> 0.4 ppm from SNI 7387-2009 and BPOM 2009, namely 0.7 ppm, 2.9 ppm, and 2.3 ppm, respectively so it is essential to have a consumption limit per week through Tolerable Maximum Intake (MTI) with categories for adults and children for the consumption of each type of fish consumption. Research shows that the maximum consumption limit for adults in kembung, tuna and tongkol is 16.9 kg, 2.8 kg, and 9.2 kg, respectively. Meanwhile, the maximum limit of consumption of kembung, tuna and tongkol for children is 6.4 kg, 1 kg, and 2.9 kg, respectively.
