Abstract

This study aims to determine the effect of fish bone gelatin addition on physical, chemical, and organoleptic characteristics of gelato. This research was done on three stages: fish bone gelatin extraction, gelato production and analysis. The treatment factor consists of concentration: 0%, 0.4%, 0.8% and 1.2% of fish bone gelatin additions. Data were analyzed by one way analysis of variant (ANOVA) at level 5% and then continued by Tukey HSD (Honestly Significant Different) test or Tukey’s range test. The result shown that fish bone gelatin addition has effect to organoleptic, physical, and chemical characteristics of gelato. The best concentration was 1.2% for fish bone gelatin addition. Gelato with concentration 1.2 % fish bone gelatin have texture, taste, colour, aroma and aftertaste range in netral until like slightly in organoleptic (hedonic) value range i.e between 2.62 until 3.70. This gelato have overrun, melting point and pH in 30.48%, 38.4 minutes and 6.6 respectively. It was contains 3.62% protein, 6.32% fat, and 15,62% sucrose. This nutrition contents was confirm with the Indonesian National for Standardization  (SNI) for ice cream groups.

Abstract

Palm oil fibers are waste products from Palm Oil Mill which is in the form of debris, solid, length of 3-4 cm, contained in coconut fruit (mesocarp) meat. Fiber roof building is the result of utilization of palm fiber waste as a roof of a building that is used to reduce heat from sunlight or from heat sources, so it is not directly exposed to humans and the surrounding environment. Fiber roof building is made by arranging the fiber in the mold and arranged in accordance with the dimensions to be made. To bind between fibers, used resin that has been mixed with the catalyst material, so easy to dry quickly. The ratio between resin and fiber is 1: ¼. The result of conduction heat conduction test that has been done on the fiber test object can reduce the highest heat of 125 °C and the lowest is 109 °C from the given heat source of 200 °C. This shows that palm fiber can be used as a heat reducer for buildings.

Abstract

Organic materials as industrial by-products are potentially used as alternative growth media composites with the aim of reducing the use of top soil and improving the quality of plants in the nursery. Mesocarp of palm fruit (fiber) and coconut fiber powder (cocopeat) are rich in plant nutrients. Composting of these by-products will be helpful in recycling and re-use of biodegradable waste useful for growing media. This research use Completely Randomized Design (CRD) one factor consist of 4 treatment. The treatment were (a). P0 = sub soil 100% (control), (b). P1 = 50% mesocarp fiber composts + 50% sub soil, (c). P3 = 50% cocopeat composts + 50% sub soil, and (d). P3 (mesocarp fiber 1 kg + cocopeat fiber 0.5 kg + 0.5 kg cattle dung) composts + sub soil 50 %. Growing media that consists of 50% mesocarp fiber and 50% sub soil (P2) was suitable as growing medium in early seedling. Compost of mesocarp fiber has the content of C-organic 52,28%, N 1,37%, C / N ratio 38,11%, P2O5 0,47%, K2O 0,89%, Mg 0,23%. The use of composted mesocarp fiber media mixed with 50% sub soil showed significant effect on the growth of seed diameter of oil palm seedlings at age 3 MAP.

Abstract

The gel strength and profile texture was the most important physical characteristic of gelatin. Unfortunately, the gelatin based on alternative source such as bone of fish has low gel strength and profile texture value compared mammalian gelatin. In another side, the extraction gelatin method has been using more saver solvent such as citric acid and water. The aim of this research was extracted gelatin from bone of fish using pineapple waste and water. Then continued with the gel strength and profile texture analysis of gelatin crude extract. The result shown that the fish bone gelatin successful extracted using pineapple waste combined with warm water at pre-treatment and main extraction respectively. The gel strength of fish bone gelatin was 430 g.bloom. Profile texture of crude extract fish bone gelatin including hardness was 9.83 N, cohesiveness of 0.46, springiness of 2.91, gumminess of 4.52 N and chewiness of 14.30. The result suggested that liquid crude extract of fish bone gelatin was comparable toward mammalian and another fish gelatin

Abstract

Indonesia must face the risks of volcanic eruptions, earthquakes, floods and tsunamis, destruction of its land areas, and resulting in damage to client and server computer systems. The demand for the information technology availability and performance becomes high. Disaster recovery plan is designed to ensure the vital business processes continuation in the event that a disaster occurs. The problem is how to make the best way in selecting backup recovery strategy based on the benefits to the cost ratio so as to minimize the business losses that will be caused by the failure of an application system. The research aims to make decisions that can help make certain parties take the best decision in choosing the backup recovery strategy selection for a business continuity plan in the University Trilogy. The method used is the multi-criteria decision making and analytical hierarchy process using the expert choice software. From the data processing results can be concluded that the first order is hot standby option 59.4%, followed by cold standby option 23.3%, then the choice of warm standby option 17.4%. The data inconsistency rate is 0.02, smaller than 0.1 as the maximum value of inconsistency ratio.
