Bacteria isolated from ad environment contaminated with heavy metals are very potential as heavy metal bioremediation agents called indigenous bacteria. The purpose of this study was to isolate and identify indigenic bacteria that have the potential as Pb bioremediation agents in agar liquid waste and to analyze the ability of indigenic bacteria in reducing Pb. The research design used Completely Randomized Design (RAL) two factorial with variation of bacteria and eight days of treatment. Data were analyzed using two-way ANOVA with Duncan's advanced test. The results showed that there were eight isolates resulting from the isolation of agar liquid waste. The isolates of liquid waste indigen bacteria so that the most potential in reducing Pb were isolated H, E and F. The three isolates were able to reduce Pb in sterile agar liquid waste by 82.6%, 81.3% and 79.3% for eight days of treatment. The identification results using Microbact TM GNB 12A / B / E, 24 Identification Kits showed that H bacterial isolates were Bacillus alvei, E isolates were Bacillus pumilus species and F isolates were Bacillus lichenformis species
White mussel (Corbula faba) is one of the fishery products belonging to the shellfish group. White mussel can be used as processed food. White mussel petis is a processed food that comes from the utilization of leftover boiled white clams mixed with granulated sugar and brown sugar and then boiled until thickened. This study aimed to analyze total plate count bacteria in the home industry for making white mussel paste in Sungikulon village, Pohjentrek, Pasuruan. This study used the total plate count method pouring technique. Analysis total plate count carried out at the Surabaya Health Laboratory Center, by testing six samples of white mussel petis and three repetitions, test data total plate count white mussel petis will be compared with SNI 2718.1:2013 to determine the quality of the sample.The results of this study indicate that the two samples do not meet the SNI 2718.1: 2013 standard, namely the SK1 sample is 82 x 103 and the SK6 sample is 22.9 x 103.. There are four samples whose values are lower than SNI 2718.1: 2013, namely the SK4 sample of 0.01 x 103. SK2 sample of 0.05 x 103. Sample SK3 is 0,11 x 103 and SK5 sample is 0.42 x 103. This means that the quality of the four samples is good.
Rumput laut merupakan salah satu komoditi hasil laut yang banyak dihasilkan di berbagai wilayah Indonesia, terutama daerah pesisir. Rumput laut Eucheuma cottonii banyak dijual baik di pasar tradisional maupun pasar modern. Eucheuma cottonii mengandung karagenan yang bersifat hidrokoloid yang memiliki sifat seperti pektin pada buah sehingga dapat digunakan sebagai bahan baku pembuatan selai. Rumput laut yang mengandung karagenan dapat menurunkan kolesterol darah. Rumput laut mengandung serat yang dapat memelihara saluran pencernaan tubuh, mencegah sembelit, kanker, dan penyakit jantung. Rumput laut mengandung Tiamin, riboflavin, niasin, dan piridoksin berperan sebagai koenzim dalam reaksi pemanfaatan zat makanan dalam tubuh. Mengkonsumsi rumput laut juga dapat membantu memenuhi kebutuhan makromineral dan mikromineral tubuh diantaranya Na, Ca, K, P, Fe, dan yodium. Rumput laut (Eucheuma cottonii) dapat lebih luas kemanfaataannya salah satunya dengan diolah menjadi selai karena kandungan hidrokoloid karagenan yang dimiliki. Selai rumput laut bersifat lebih awet dibandingkan rumput laut basah dan praktis untuk dikonsumsi ataupun diaplikasikan dalam pembuatan produk pangan yang lain. Hasil uji kesukaan pada selai rumput laut menujukkan rerata skor rasa 3,6 artinya selai rumput laut yang dihasilkan memiliki rasa manis yang pas dan enak saat dimakan. Rerata skor tekstur 3,5 artinya tekstur selai rumput laut halus. Rerata skor warna 3,6 artinya warna selai rumput laut berwarna kuning keemasan. Rerata skor aroma 3,7 artinya aroma selai rumput laut cenderung segar dan menimbulkan selera makan. Rerata skor penerimaan keseluruhan 3,7 artinya selai rumput laut yang dihasilkan disukai oleh panelis. Oleh karena itu, selai rumput laut dapat diaplikasikan pada pembuatan pie dan bolen. Pie selai rumput laut yang dihasilkan menunjukkan rerata skor tekstur 3,5 artinya kulit pie renyah, mudah rapuh, dan lumer di mulut. Rerata skor rasa pie selai rumput laut 3,5 artinya memiliki rasa gurih dan manis yang seimbang. Rerata skor warna pie selai rumput laut 3,7 artinya memiliki warna kuning kecoklatan dan menimbulkan selera makan. Rerata nilai aroma 3,6 artinya kulit pie menghasilkan bau khas yang wangi dan menimbulkan selera makan. Rerata hasil penerimaan keseluruhan yaitu 3,8 artinya pie selai rumput laut disukai panelis. Bolen rumput laut yang dihasilkan menunjukkan rerata skor tekstur 3,4 artinya tekstur kulit kue bolen selai rumput renyah. Rerata skor rasa bolen rumput laut 3,4 artinya memiliki rasa gurih dan manis yang seimbang, rerata skor aroma 3,4 artinya menunjukkan aroma wangi dan menggugah selera, rerata skor warna 3,5 artinya warna kue bolen selai rumput kuning kecoklatan. Rerata penerimaan keseluruhan kue bolen selai rumput laut 3,5 artinya disukai oleh panelis. Pie dan bolen selai rumput laut menjadi inovasi dalam diversifikasi dan pengembangan produk perikanan sehingga dapat membantu konsumen pecinta kue khususnya kue pie dan bolen mendapatkan nilai gizi dan manfaat dari rumput laut.
