Abstract

Attention and handling in disaster mitigation efforts. According to Law no. 24 of 2007 concerning Disaster Management, fires are categorized as natural disasters as well as non-natural disasters based on their causes. This indicates that fire disasters, apart from being affected by physical or natural conditions, can also occur due to human negligence as the cause. There are four fire safety components, namely fire protection facilities, fire engine access, life-saving facilities and Fire Safety Management Building (MKKG). Various fire incidents that occur can be caused by the absence or ineffective functioning of early detection systems, fire extinguishing systems and rescue systems. Therefore, it is important to know how to assess the availability of types of active fire protection system tools at the main campus of Universitas Negeri Padang as an effort to improve fire prevention and management. This study uses mixed methods (quantitative and qualitative) with a descriptive approach by determining the category of the condition level of the active protection system.

Abstract

The edible film is a bioplastic in the form of a thin layer that can be decomposed with the help of microorganisms. This study aims to determine the effect of adding chitosan to the edible film of durian seed starch on the mechanical properties and structure of the edible film. This research was conducted by varying the concentration of chitosan at concentrations of 0%, 0.5%, 1%, 1.5%, and 2%. The resulting edible films were analyzed for tensile strength, elasticity, and characterization using Thermogravimetric Analysis (TGA). The optimum tensile strength obtained with the addition of 1% chitosan is 1.414 Mpa. The maximum elasticity value obtained in the edible film with the addition of 1% chitosan is 436.2 Mpa. The thermal resistance of the film will be higher as the tensile strength increases. The film begins to decompose at 250 ºC and ends at 500 ºC.

Abstract

Edible film is a thin plastik with a thickness of less than 0.25 mm which is often used to protect food products. This study aims to determine the effect of adding variations of carrageenan to the mechanical properties of edible film from yam starch. This research used polyethylene glycol (PEG) plastikizer and carrageenan variations (0.5%, 1%, 1.5% and 2%). The resulting edible film was analyzed for its mechanical properties. The higher the addition of carrageenan concentration, the thicker the edible film produced, and the maximum yield was obtained at the tensile strength of 2.92 Mpa and elasticity 7.02 Mpa at the addition of 1% carrageenan, the minimum elongation value of 0.41% at the addition of 1% and 1.5% carrageenan. The results of this study indicate that the addition of carrageenan variations affects the mechanical properties of the edible film.

Abstract

Breadfruit has a fairly high starch content of 84.28%, the utilization of breadfruit itself is still not optimal. In Indonesia, breadfruit can thrive in one of the breadfruit-producing cities, namely the city of Padang. One of the uses of breadfruit is in the manufacture of edible films. Edible film is a thin plastic that has a size smaller than 0.3 mm which serves to protect food products. The purpose of this study was to determine the effect of carrageenan on the tensile strength and biodegradation of edible films from breadfruit starch. This study used the addition of carrageenan with variations in concentrations of 0%, 0.5%, 1%, 1.5%, and 2%. Edible film was tested for tensile strength and obtained values ​​at 0% 2.046, 0.5% 4.252, 1% 7.678, 1.5% 4.139, 2% 3.829 where the optimum tensile strength value was at 1% with a tensile strength of 7.678 Mpa while the biodegradation had percent loss at least at a concentration of 2% with a percent loss yield of 11.5%. The higher the concentration used, the more difficult it is for the edible film to be degraded in the soil.

Abstract

Abstract : Edible film is a thin plastic with a thickness of less than 0.25 mm which serves to protect food products. The purpose of this study was to determine the optimum concentration of addition of chitosan to edible film made from avocado seed starch on mechanical properties and to compare the mechanical properties of edible film with the value of Japenese Industrial Standard (JIS) Z1707. This research was conducted by adding 4% polyethylene glycol as a plasticizer and varying the addition of chitosan with a concentration of 0%; 0.5%; 1%; 1.5%; and 2%. The optimum conditions for the addition of chitosan at a concentration of 1%, with a tensile strength value of 1.235 Mpa, an elasticity value of 4.643 Mpa, and an elongation value of 0.266 Mpa. The tensile strength and elasticity values of the edible film have met the Japenese Industrial Standard (JIS) Z1707 but the elongation value has not met because the edible film produced is fragile so it breaks easily and causes the edible film to have a low elongation value.
