Interactions between plants and endophytic bacteria are mutualistic. Plant provides nutrient for bacteria, will protect the plant from pathogen, help phytohormone synthesis nitrogen fixation, also increase absorption of minerals. These called growth-promoting bacteria. The aim this study is to identify on rambutan (Nephelium lappaceum L.) cultivar Binjai with 16S rRNA. Sequencing results showed that derived genus Corynebacterium, Bacillus, Chryseobacterium, Staphylococcus Curtobacterium,...

Low-salt shrimp paste, or terasi, is an Indonesian fermented food made from planktonic mixed with a low concentration of salt. Since high daily intake sodium deemed unhealthy, reduction salt content in paste production desired. Until now, there no reported investigation on the bacterial population and metabolite composition terasi during fermentation. In this study, community was assessed using high-throughput sequencing 16S rRNA V3-V4 region. From analysis, Tetragenococcus, Aloicoccus,...

Tempe is fermented soybean from Java, Indonesia, that can serve as a functional food due to its high nutritional content and positive impact on health. Although the tempe fermentation process known affect nutrient content, changes in metabolite profile during production have not been comprehensively examined. Thus, this research applied metabolomics approach investigate each step of production, soaking over-fermentation. Fourteen samples raw soybeans, i.e., soaked soybeans (24 h), steamed...

Abstract This research reports the optimization of synthesis bacterial nano cellulose (BNC) from banana peel waste media Kepok bananas ( Musa paradisiaca L .) using Gluconacetobacter xylinus bacteria in a fermentation process for use water filter membrane applications. Bacterial nanocellulose was successfully accomplished under conditions pH 4, 0.5% urea, and varying sucrose contents (5%, 10% 15% (w/v)). The higher content causes extract solution to decrease at end Day 8 10 due metabolic...

The imbalance of supply demand increases risks in the primary actors chain. This study aims identify, assess, determine risk factors through FMEA, mitigation strategies for chain KCS an Analytical Hierarchy Process (AHP) analysis. Ten were identified farmers, nine product manufacturers, seven distributors/retailers. priority factor at farmer level pests disease...

Abstract This research reports the result obtained from synthesis and characterization of Bacterial Nano Cellulose (BNC) Nangka banana peel (Musa sp L.) media for water filtration membrane application. The BNC is successfully achieved under condition ratio 1:3, bacterial nutrition : Glucose 10% (w/v), Ammonium Sulphate (NH 4 ) 2 SO 1% pH: 4, amount starter: 15% (w/v). duration fermentation 7 days. content in 86,59%. Scanning Electron Microscopy (SEM) analysis shows resulting nanocellulose...

Abstract The objective of this review article is to investigate rheological behaviors starch‐based biopolymer mixtures in selected food systems. Numerous recently published studies on subject were thoroughly screened and reviewed. This paper indicates behaviors, which include viscoelasticity, texture, viscosity, It was found that had different could affect the quality processed foods. main factors affected properties botanical sources starches effect mixing other biopolymers with starch. For...

Vocational village is a set as model for developing its local resources in order to improve the life of inhabitants.The potential commodities developed at Panawangan are fishery, ranch, and agriculture.Those using simple biotechnology principle such White Organic Pomfret fishery.The training method provided was experiments that include parent preparation, larviculture with re-circulation system, growing, organic fermented feed, fishery products.The size pond 9,433.32m2 it belongs 30...

Microbial communities in an acidic hot spring, namely Kawah Hujan B, at Kamojang geothermal field, West Java-Indonesia was examined using culture dependent and independent strategies. Chemical analysis of the spring water showed a characteristic acidic-sulfate activity that contained high sulfate concentrations low pH values (pH 1.8 to 1.9). community present characterized by 16S rRNA gene combined with denaturing gradient gel electrophoresis (DGGE) analysis. The majority sequences recovered...

Coffee is an important export commodity for Indonesia, which able to contribute a sizeable foreign exchange. West Bandung Regency regency in Java province have significant potential the development of Arabica coffee commodity. Suntenjaya village, Lembang district one coffee-producing areas regency. However, there are some obstacles arabica farming including land resources utilization, harvest and post-harvest, quality institutional aspects. Therefore, it necessary formulate business...

The use of close aquaculture system including Recirculation Aquaculture System (RAS) has been implemented to allow a more stable water quality, good hygiene and efficient resources in wide shrimp production.This study aims optimize stocking density evaluate microbial community profile super-intensive culture Pacific white (Litopenaeus vannamei) using RAS technology at low salinity.Before stocking, post larvae was gradually acclimatized from salinity level 32 ppt 5 within 14 days.Different...

Cultivable rhizospheric and endophytic bacteria were isolated from cilembu sweet potato during the 5 mth period post planting to assess diversity dynamics of its bacterial community. The number colony forming units was significantly higher than for bacteria. genera richness associated with in early stages growth last stages. different cultivable identified using 16S rRNA gene sequencing as: Alphaproteobacteria (Methylobacterium, Sphingomonas, Paracoccus), Gammaproteobacteria (Klebsiella,...

Abstract This study assessed the effect of poly‐β‐hydroxybutyrate ( PHB ) on growth, survival, and disease resistance Pacific white shrimp Litopenaeus vannamei . A 20‐d feeding test using 30‐d‐postlarval (100 shrimp/tank) tested three different diets: 0.3 g /kg diet, 0.5 commercial feed containing no as control. The was followed by a 10‐d bacterial challenge Vibrio harveyi After test, highest average final body weight, specific growth rate, total biomass (mean ± SD = 0.44 0.28 g, 28.82...

In this study, the effect of red seaweed Kappaphycus alvarezii by-product meal on growth, survival, and disease resistance white shrimp Litopenaeus vannamei against Vibrio harveyi was evaluated in nursery phase.Shrimp fed for 30 days with four different diets: control (0 g kg -1 ), 5 , 10 15 supplemented feed.The supplementation at higher concentrations (10 ) found to increase survival shrimp, even though not significantly.The highest total biomass obtained group diet (P>0.05).Following...

In recent times, the indiscriminate disposal of post-consumer plastic packaging material has received global attention. There is a need to develop an alternative from bio-based polymers reduce waste pollution.
