Abstract

Dadih merupakan pangan fermentasi susu kerbau secara tradisional,dalam tabung bambu, rasa masam, kental dan enak. Di era globalisasi dadih menjadi popular karena mampu mengurangi kolesterol-darah (71,75%), dan menekan pertumbuhan kanker (27,83%). Saat ini penampilannya dikembangkan dengan NTG (mutagenic substance) untuk menghasilkan mutan Lactococcus lactis ssp. lactis yang meningkatkan ferformannya (menekan kanker = 72,51%). Sebelumnya, telah diakui mutan Lactococcus lactis ssp.lactis menghasilkan Bacteriocin-nisin yang menjaga kesehatan masyarakan pedesaan karena menghambat pertumbuhan mikoba-patogen (Escerichia coli=1,0; Staphylococcus aureus = 0,7; dan Salmonella thypii = 0,7) index mikroba. Untuk mengantisipasi rasa dadih terhadap selera konsumen, diversifikasi produk dadih telah dikembangkan, sehingga pemanfaatannya sebagai probiotik mampu meningkatkan kesehatan masyarakat.

Abstract

This research was conducted to determination the optimum activity of endogenous PG enzyme in cocoa pulp using response surface methodology. The results of this research had benn used as reference to develop the condition of fermentation mechanism in cocoa processing. This research was carried out by assaying the enzyme activity for 60 minutes on varying of temperature and pH. The treatment of temperature were 30, 40, 50 and 600C and pH were 3,5; 4,0; 4,5; 5,0; 5,5 respectively. Determination the optimum activity of endogenous PG enzyme in cocoa pulp using response surface methodology. The result showed that optimum condition of activity of endogenous PG enzyme was the combination of temperature 42,50C and pH 4,6 with regression model of response surface curve: Y= 750+2.27 X1 – 0,0434 X12 + 0,000260 X13 – 721 X2 + 245 X22 – 36,5 X23 + 2,01 X24, with R2= 0,929.

Abstract

A green house that roofed by using transparent materials such as glasses, fiberglass, plastic, etc. could provide an optimum growth environment for plants such as mushrooms. However, green house effect during the day leads to a higher temperature inside the green house in comparison to the outside temperature. In order to provide an optimal environment for growing mushrooms in a green house, it is required a temperature machine control which is able to bring the room temperatures between 160C to 210C. The dynamic of room temperature can be predicted by using a mathematical model simulation. A stimulation model developed by using Matlab program could be implemented in a temperature control machine in order to bring the room temperature between 160C, 190C and 210C. Research results showed that it took 16.8 minutes, 26.4 minutes, and 30 minutes to bring the room temperature down to 160C, 190C and 210C respectively. When the room temperature reaching the target temperature, the room temperature were varying within 0.010C.

Abstract

MA storage combined with cold storage has been wellknown for its advantages in storing fresh produces. So, inthis research an attempt was carried out to determine the MAof fresh Pondoh snake fruit. Two levels of low O2 concentrationswhich combined with four levels of high CO2 wereapplied to find out the proper MA storage for the fresh fruitat temperature of 10 and 15oC. A storage of the fruit atnormal atmosphere was also made as a control. Qualitymeasurements were done on hardness and colour of the fruitpulp.Experiments showed that only four O2 – CO2 combinationsthat gave better fruit responses, when the fruit wasstored for 18 days at 10 and 15oC. So, it was suggested thatthe MA storage of fresh Pondoh snake fruit was at 4 ± 2% O2with 14 ± 4 CO2 for 18 days storage at 10 and 15°C.

Abstract

Carrot syrup processing involves thermal boiling process.Unsuitable process will decrease the product quality. Besidestemperature, using uncovered or covered pan also needattention. So how thus effects to the product characteristicneed further study. The aim of this research was to find out:1) effects of covered cooking and temperature oncharacteristic of carrot syrup, and 2) the treatmentscombination yield the best characteristic. This research wasdesigned with factorial randomized block design consist oftwo factors. First factor is cooking method with two level,those are uncovered and covered cooking. Second factor iscooking temperature, consist of four levels, those are 70o,80o, 90o, and 100o C. Each treatment repeated twice so yield16 experiment units.The research showed that interaction between the twotreatments affected the vitamin C content and viscosity.Covered cooking and temperature treatment influenced thebeta-carotene content and the reduction of sugar level. Thetreatments also affected the sensory quality, especially oncolor, flavor, and taste acceptability. Based on the analysis ofall variable, the treatments combination yielding the bestcharacteristic was uncovered cooking treatment ontemperature 70oC. The best treatments characterized by 6,81ppm beta-carotene content; 3,59% reduction sugar level; 4,14mg/100 g vitamin C content; viscosity 81,17 cP; coloredorange type 2 (based on colour-chart), typical of carrotflavor, and acceptable for color, flavor, viscosity, taste, andoverall acceptance.

Abstract

Salak (Salaca edulis Reinw.) is one of Indonesia’s indigenous tropical fruits,which has given a priority being developed as one of an export horticulturalcommodity. One of problems which causes in difficulty of marketing of this fruit isthat it contains high concentration of tannin of which gives an astringent taste of thefruit. Therefore, this research has tried to reduce this taste by applying ethanolsolution and vapor to the intact fruits.The result indicated that by applying ethanol both as solution and vapour hassignificantly reduced the concentration of tannin of the salak fruit. Other beneficialeffects of ethanol were to increase the total soluble solid and reduce the acidity of thefleshy part of the fruit. All these effects could bring a new market development forsalak fruit. Further research, however, should be performed to identify the minimumconcentration of ethanol in the fleshy of the fruit to give significant reduction of thetannin and the threshold concentration of ethanol to give a taste of ethanol in thefleshy fruit.

Abstract

This research objective was to know the profile of an area which will be developed as an agro-tourism area in order to increase the economic activities of the area. The profile of the area was studied through a potency analysis by using a factor analysis on several economic potential namely agro-estate, industry, and tourism. Meanwhile, the projection analysis od estate commodity production and tourism arrival when using a forecasting method. Jembrana Regency has some centers of estate commodity which could developed as an agro-tourism area. This potency is also supported by the existence of industrial sector and the increasing trend of tourism arrival. So that, development of new tourist objects, such as agro-tourism at Jembrana Regency is still prospective.

Abstract

The objectives of this research were to study the physical, chemical, and microbiology properties of Banana Leaf as traditional packaging materials at severals length of blanching time, and to determine the type of banana leaf which has the best packaging materials properties. Five types of banana leafs were observed and treated by steam blanching for 2, 4, and 6 minutes. The parameters observed included tensile strength (ASTM D-826), tear strength (ASTM D-687) moisture permeability (desican method), gas permeability (pressure increased method), porosity (ASTM D-726), thickness, weight per surface area, moisture content, oil and acid resistent, and total microbes. The results indicated that different type of banana leaf had different properties, and blanching treatment had significant effect on tensile strength, tear strength, porosity, thickness, weight per surface area, misture content, oil and acid resistant, and total microbes. The type of banana leaf that had the best properties as traditional packaging materials was “pisang kepok” that blanching for 2-4 minutes.
