Abstract

A The purpose of this research was to figure out the affinity value of soluble carbohydrates from pollard with lactic acid bacteria (LAB) and its effect on tofu waste silage. Lactic acid bacteria (LAB) isolates used as inoculum were commerce LAB isolates (B13-1) and yolk LAB isolates (K6-3). The selected of LAB isolates used in the tofu waste silage were tofu waste (TW) and pollard (P) with different proportion (70:30), (60:40), and (55:45). The result showed that the addition of soluble carbohydrates sources in the tofu waste silage did not affect lactic acid and pH value. However LAB addition significantly increased lactic acid (P<0.05). The TW:P proportion (55:45) produced the highest lactic acid concentration with the value of 3.54%DM with pH value 3.90. Proportion of TW:P gave significantly different effect on dry matter (DM) and organic matter (OM) (P<0.01). Meanwhile, LAB addition presented significant difference in declining of dry matter percentage (P<0.01) but it showed non-significant effect on organic matter percentage from the tofu curd silage. It can be concluded that pollard addition with the value of 45% shows that tofu waste silage has the highest lactic acid concentration and ideal pH value.

Abstract

This study examined the characteristics of the edible film mixture gelatin bovine split hide and soy protein isolate, cross-linked using transglutaminase enzyme with addition level of glycerol as a plasticizer.The material used gelatin  combination (Gelatin bovine split hide: soy proteinisolate = 90: 10 with 30 Utransglutaminase enzyme levels ), and glycerol. Data were analyzed  using completely randomized design each treatment was replicated thrice of glycerol as a treatment level ( 10%, 20% dan 30%). The results showed that the glycerol level significantly affected the thickness, elongation, solubility, degree of cross-linking and WVTR, but not the tensile strength.The addition of glycerol causing the film becomes more elastic and  the surface is more homogeneous and compact. Increasing the level to 30% glycerol affects the mechanical properties of an edible film.

Abstract

 ABSTRACT Integrated farm is a model for the management of local resources’ potential by integrating livestock and crops into eco-friendly farming (zero waste). It can be the answer for the country’s basic needs of food that is still dependent on imports. Most of the habitants of Argorejo and Argosari village work as farmers and ranchers. Although the formal education of rural people is still low due to low income, the average member of activities to get information, knowledge and management skills in agribusiness sectors to understand the practical, economical, and effective ways in business development. It facilitates adoption of innovation and the process of information absorption. Adoption of innovation is a process of mental or behavioral changes in the form of knowledge (cognitive), attitudes (affective), and skills (psychomotor) since one recognizes the innovation until one decides to adopt it after receiving it. This is qualitative research, with research material in the form of members of agribusiness activities in the intervention program called Mandiri Bersama Mandiri. The method used is descriptive analysis. The data is collected by interview, observation, and records related to the activities of the group. The result of Classification Analysis with Adopter type shows that 7 of the 8 groups in the facilitation of innovation adoption of integrated farms have: 6.7% to 14.3% innovator; 8.3% to 18.2% early adopter; and the rest is 71.4% to 77.8% early majority. One group has no innovator and up to 50% early adopter. The innovators of Mandiri Bersama Mandiri program include the most influential people that have important positions, such as group leaders, village officials, or persons who have knowledge. It indicates that the potential success of the intervention program is located on the adopter type that exists in each member, absorption of new innovations adoption, and succeed in the community empowerment program.
