Tingginya kebutuhan minyak sawit Indonesia mendorong pihak produsen untuk meningkatkan produksi industri minyak sawit seoptimal mungkin. Pengembangan industri minyak kelapa sawit ini menyerap banyak tenaga kerja, namun disisi lain menimbulkan limbah cair yang berbahaya bagi lingkungan. Tujuan dari praktek lapangan ini yakni untuk mengetahui menganalisis parameter BOD, COD, pH, TSS, N-Total pada limbah cair kelapa sawit (LCKS) dari pabrik kelapa sawit (PKS) dan untuk mengetahui parameter BOD, COD, pH, TSS, N-Total pada limbah cair kelapa sawit sudah memenuhi syarat sesuai dengan Baku Mutu berdasarkan Keputusan Menteri Lingungan Hidup No 29 Tahun 2003 tentang Pedoman dan Tata Cara Perijinan Pemanfaatan Air Limbah Industri Minyak Sawit. Adapun hasil dari parameter yaitu kandungan dari BOD tidak memenuhi standarisasi karena lebih dari 100mg/l di dapat hasilnya mencapai 278 mg/l dan COD tidak memenuhi standarisasi karena lebih dari 350 mg/l dan didapatkan hasinya 620 mg/l. Sedangkan TSS sudah memenuhi standarisasi karena kurang dari 250 mg/l dan didapatkan hasinya 80 mg/l, N-Total sudah memenuhi standarisasi karena kurang dari 50 mg/l hasilnya mencapai 15 mg/l, dan pH sudah memenuhi standarisasi karena kurang dari 9 mg/l dan didapatkan hasinya 8,2 mg/l.","PeriodicalId":166721,"journal":{"name":"Jurnal Enviscience","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120973145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

So far, cow dung in the petiyen village has only been cleaned and thrown away for nothing without further use. One alternative to overcome this problem is to utilize cow manure as organic fertilizer. In addition to the waste generated from cows in general the petiyen community also produces waste from its household activities. Of the 2 types of organic waste in the form of cow waste and household waste will be processed into organic fertilizer which will be applied to rice and corn plants that are widely grown by farmers in Petiyen Village, Solokuro Subdistrict, Lamongan Regency. The purpose of this study was to determine the effect of the use of organic fertilizer on plant growth. This research method is experimental. The results showed that the average plant height was 13 cm for the use of organic fertilizer media only and 12 cm for mixed organic fertilizer and soil media, while for chemical fertilizer media could not grow. Root length on day 9, which uses 13 cm organic fertilizer media and which uses a mixture of organic fertilizer and 10 cm soil. it can be concluded that organic fertilizer affects the growth of green bean plants .","PeriodicalId":166721,"journal":{"name":"Jurnal Enviscience","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121931715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Meatballs are processed food who are using meat as main ingredient and other ingredients, such tapioca flour, salt, pepper, and the other ingredients as food additives. Meatballs is the mostpopular because has tasty flavor, high protein content, especiallyessential amino acids.In Indonesia, until now there were still cases of counterfeiting of processed meat products. One of method is mixing the beef meat and other animalsmeat in the making process to reduce production costs, so that similar products can be obtained at a much lower cost. One common case is the mixing of beef meat with rat meat. This study aims to identify meatballs contaminated by rat meat. Meatball samples used do not have Halal certificate from LPPOM MUI. From the results of the study, obtained the green amplification curve with the highest peak showed positive control of rat DNA, followed by three other green curves from the sample that showed the occurrence of amplification, thus indicating samples positive containing rat DNA. In the positive sample, the rat DNA concentration in the sample is quite low which can be seen from the intensity of the peak produced on the amplification curve when compared with positive control.
