The purpose of this research was to get the best treatment addition of microorganisms B-DECO3 as a reducing agent contamination of waste pollution palm factory with the addition of microalgae Chlorella sp. This research used a Completely Randomized Design (CRD)with 5 treatments and 3 replications. The treatment used against waste pollution palm factory was P0 (without addition of B-DECO3 microorganisms), P1 (addition 5ml/L of B-DECO3 microorganisms), P2 (addition 10 ml/L of B-DECO3 microorganisms), P3 (addition 15ml/L of B-DECO3 microorganisms), P4 (addition 20 ml/L of B-DECO3 microorganisms). The data obtained were analyzed statistically using Anova and DNMRT at 5 % level. The result showed that the addition of microorganism B-DECO3 had significant affect for COD, BOD, TSS, oil, and pH. The treatment chosen from the result of this research was the P4 treatment which had a value of COD (330,63 mg/L), BOD (94,53 mg/L), TSS (266,46 mg/L), Oil (2,50) and pH (8,64).
Biopreservation of food using bacteriocin from lactic acid bacteria (LAB) was an innovative breakthrough. Lactic acid bacteria can protect against food spoilage and pathogen bacteria by producing bacteriocin. The purpose of this study was to characterize the bacteriocin produced by LAB isolated from solid waste of soymilk that had probiotics properties. The LAB having antibacterial activities was evaluated their growth, and identified by using 16S rRNA gene sequence analysis. Its bacteriocin activities was tested on various pHs (2, 3, 4, 5, 6, 7, 8, and 9) and temperature (60-100 ° C). Its activities was evaluated againts pathogenic bacteria (Staphylococcus aureus ATCC 25923 and Listeria. monocytogenes CFSAN004330), enzymes (trypsin, catalase and protease-K), and antibiotics (penicillin and ampicillin). The results showed that LAB A23.4 isolates, which had 16S rRNA gene sequence were L. plantarum strain TMW 1.1623. Its Bacteriocin had antimicrobial activity against S. aureus ATCC 25923 and L. monocytogenes CFSAN004330 at pH 2-7, at temperatures of 60, 70, 80, 90, 100 ° C for 60 minutes and lysed by the enzymes trypsin and protease-K. Bacteriosin activity was stronger than that of the antibiotics of penicillin and ampicillin against S. aureus and L. monocytogenes. The inhibition zone of supernatant bacteriocin was 10 and 20 mm for S. aureus and L. monocytogenes. On the other hand, penicillin and ampicillin inhibition zones were 0 and 3 mm, respectively. From these results, it can be concluded that the antimicrobial produced by L. plantarum strain TMW 1.1623 was a bacteriocin used as food preservation that its processing using relatively wide range temperature (60-100) with pH 2-7.

Penelitian menggunakan rancangan acak lengkap yang terdiri dari 4 perlakuan dan 4 ulangan. Perlakuan dalam penelitian ini adalah batang pepaya ml (P1), penambahan ekstrak batang pepaya 15 ml (P2), penambahan ekstrak batang pepaya 20 ml (P3), penambahan ekstrak batang pepaya 25 ml (P4). Parameter yang diamati adalah kadar air, kadar asam lemak, asam lemak bebas / alkali bebas, pH, stabilitas busa, uji antibakteri dan uji iritasi. Hasil penelitian menunjukkan bahwa penambahan ekstrak batang pepaya berpengaruh nyata terhadap kadar air, kadar asam lemak, asam lemak bebas, pH, stabilitas busa, uji antibakteri dan uji iritasi. Perlakuan yang dipilih dalam penelitian ini adalah perlakuan P3 (penambahan ekstrak batang pepaya 20mg / ml) dengan kadar air 13,24%, asam lemak total 27,00, asam lemak bebas 1,73%, pH, 11,06, stabilitas busa 90,99%, aktivitas antibakteri terhadap S. aureus 8.57 mm dan E.coli 10.33 mm, iritasi erythema 0.05 (hampir tidak terlihat).
Biji ketapang merupakan bahan pangan lokal yang pemanfaatannya belum optimal. Kandungan lemak dan protein yang tinggi pada biji ketapang memungkinkan untuk digunakan sebagai bahan pembuatan mayones dalam upaya meningkatkan diversifikasi pangan. Minyak yang biasa digunakan untuk membuat mayones adalah minyak kedelai. Tujuan dari penelitian ini adalah untuk mendapatkan formulasi mayones minyak kedelai dan pasta biji ketapang terbaik yang sesuai dengan persyaratan mutu mayones. Penelitian ini dilakukan secara eksperimen dengan menggunakan rancangan acak lengkap non faktorial dengan lima perlakuan dan tiga ulangan. Data yang diperoleh dianalisis secara statistik menggunakan Analysis of Variancedan dilanjutkan dengan uji Duncan’s New Multiple Range Test. Hasil penelitian menunjukkan bahwa perbandingan minyak kedelai dan pasta biji ketapang berpengaruh nyata terhadap kadar air, kadar abu, kadar lemak, kadar protein, kestabilan emulsi, viskositas, dan karakteristik sensoris warna, rasa, dan kekentalan. Perlakuan terbaik dalam penelitian ini adalah perbandingan minyak kedelai dan pasta biji ketapang (90% : 10% b/b) dengan kadar air 20,35%, kadar abu 1,35%, kadar lemak 68,44%, kadar protein 3,95%, viskositas 103.556 cP, dan kestabilan emulsi sebesar 99,23%. Hasil uji deskriptif menunjukkan mayones berwarna kuning kecokelatan, agak beraroma minyak kedelai, berasa minyak kedelai, kental, serta disukai panelis secara keseluruhan.
The purpose of this research was to obtain best consentration of CaO catalyst chicken eggshell in transesterification process on quality of biodiesel produced from pangi seed oil. The treatment of CaO catalyst concentrations in this research was S1 (1%), S2 (1.5%), S3 (2%), S4 (2.5%), and S5 (3%). The collected data were statistically analyzed by using Analysis of Variance (ANOVA) continued by Duncan’s New Multiple Range Test (DNMRT) test at 5% level. The parameters observed were acid value, density, iodium value, saponification value, and cetana number. The results of analysis showed that consentration of CaO catalyst chicken eggshell gave unsignificantly affect on acid value and cetana number but significantly affect on density, iodium value, and saponification value of biodiesel. The chosen treatment in this research was S5 (CaO catalyst 3%). The treatment of S5 has yield 97.99% with characteristics acid value 0.68 mg KOH/g, density 885.22 kg/m3, iodium value 81.41 g I2/100 g, saponification value 179.00 mg KOH/g, and cetana number 58.48.
