Abstract

The beauty and benefits of plants in the Green Open Space are often disturbed by mistletoes. The existence of mistletoes often indicates the occurrence of disturbances or damage to the host plants that are parasitized. The mistletoes has been widely known by the community, but has never received attention in handling it. There has been little research on crop damage or loss caused by mistletoes. The purpose of this research is to know the existence of mistletoe and to know the pattern of distribution of mistletoe in green open space of Surabaya city. The study was conducted using the exploration method with emphasis to observe the distribution of mistletoes and identification of the type of mistletoe obtained. The results showed that the distribution of mistletoes in green open space in Surabaya tend to be grouped according to the distribution pattern of host plants. There are three types of mistletoes that mistletoe green open space plants in the city of Surabaya namely Dendrophtoe pentandra (L.) (very dominant), Macrosolen cochinchinensis (Lour.) Van Tiegh, and Henslowia frutescens.Champ Keywords: Kind of Mistletoe, Distribution Pattern, Green Open Space, Plant.

Abstract

Purchasing Consortium (PC) is a strategy in purchasing wich two or more organizations with separate legal entities are merged either individually or through third parties. The main problem that arises in a PC is how to allocate the savings obtained to each member. Generally, the contributions given by each buyer in the purchase differ from one another. Allocation of savings equally to each buyer is no longer representing the contribution of each buyer.The purpose of this study is allocated savings using the Shapley value method of the cooperative game theory. Where each buyer obtained a saving allocation that is in accordancewith his contribution.Based on the results of the Shapley value, the results of saving allocations were matched with the contributions of each member who joined the PC. Where buyers 1 with a larger contribution get a greater contribution than the others. Keywords: Purchasing consortium, Shapley value

Abstract

Wet noodles as a source of carbohydrates have a moderate GI value that is 53-56. For this reason, engineering processes was needed to reduce GI value so that it becomes safe and healthy food. Tea (Camellia sinensis) contains tannin polyphenols which can reduce protein and starch digestibility so that the glycemic response decreases. The addition of tea extract to the noodleswill result in changes in product properties, so that research on quality of wet noodles with tea extract addition was needed. This research used Factorial Randomized Block Design. The first factor was tea type with two levels and second factor was tea extract concentration with three levels. The parameters observed were organoleptic test, namely taste, aroma and color, and chemical tests, namely protein and tannin content. The research conclusion were: (1) based on organoleptic test, the addition of green tea was preferred over black tea, (2) the addition of green tea and black tea did not caused significant differences in protein content, (3) the tannin content with the addition of green tea tends to be higher than black tea, and (4) the selected treatmentwas T1K1 (addition of 1% green tea extract) containing 5.81% protein and 15.39% tannin. Keywords: Wet Noodles, Tea Extract, Organoleptic, Protein, Tannin.

Abstract

The population of Sidoarjo Regency with a relatively high number and growth rate has consequences for the increase of waste produced volume. Increasing of volume waste is directly proportional to the increase in population, meaning that amount of waste produced is increasing (organic and inorganic waste). The TPA center in one of the garbage collection locations in Sidoarjo Regency has exceeded capacity (overload). This research was conducted with the aim of describing initial model of the distribution of waste used, evaluating initial performance model of waste distribution in Sidoarjo Regency, and providing recommendations to propose improvements in the waste distribution model used. The method applied in this study was using simulation. Based on the simulation results, the Third Scenario proposed the route with the most efficient distance, this affected the vehicle's operational time and the operational costs needed. Keywords: Waste, Distribution of Waste, Simulation, Shorthest Route.

Abstract

The skin is an organ of the human body that functions to protect from outside influences. Damage to the skin will interfere with human health so that the skin needs to be protected and maintained its health. One of the things that causes skin damage is freeradicals. To prevent skin damage from free radicals, an antidote is needed, namely antioxidant compounds. One source of natural antioxidants is petai bark extract (Parkia speciosa). In this study, petai bark extraction was carried out by using ethanol solvent.The dried petai powder was macerated with ethanol solvent for 24 hours, then solvent separation was carried out by using a rotary evaporator so that the extraction was concentrated green. The antioxidant activity in petai bark extract was observed through qualitative tests using DPPH reagent. The test results showed that the positive petai bark extract had antioxidant activity. The final stage of this study was to mix petai bark extract with skin lotion preparations. Based on the results of this study, petai bark waste which was originally of non economic value can be optimized to be an unique product and has high benefits. Keywords: Antioxidants, Ethanol Extract, Lotion, Petai Bark (Parkia speciosa).

Abstract

Rice bran oil as an alternative edible oil is promising to be developed. However, the presence of lipaze enzym which hydrolyze actively trigliceride into free fatty acid results rice bran quality can not be controlled and tend to degrade. Stabilization proccesswas needed to overcome this isue. Stabilization with microwave heating has been carried out to study the effect of stabilization toward the quality of rice bran oil. The results showed that the highest percentage of oil mass 7.67% was obtained at mediumpower (power 2), stabilization time 1 minute and the extraction waiting time for 0 week. Meanwhile, the levels of free fatty acids tended to be constant when the proccess was carried out at power 3 (high power) for all stabilization times. Microwave heating was effective enough to reduce the lipase enzyme in rice bran so as free fatty acid content did not increase significantly. Keywords: Microwave Heating, Rice Bran Oil, Stabilization.

Abstract

The rapid development of the country in Indonesia, especially in the fields of industry and technology, is inseparable from the problem of air pollution, especially in the environment, namely pollutant gas and dust. Air pollution needs to be environmentallyfriendly by increasing the amount of vegetation or reforestation by planting tree species that have the ability to grow and absorb pollutant gases and absorb dust particles in polluted environmental conditions. The study uses descriptive analysis by assessing tree elements macroscopically to select the appropriate tree species and can be recommended as an absorber of gas pollutants and dust absorbers based on tree suitability scoring. The results showed that of 7 (seven) dominant tree species identified, there were 3 (three) dominant tree species that were very suitable, 3 (three) dominant tree species were suitable, and only 1 (one) dominant tree species were not suitable for air pollutant gas. Whereas the evaluation of the function of dust particle absorptionshows that all dominant tree species studied have the appropriate criteria in absorbing dust with the acquisition of 65% -75% evaluation value. Keywords: Dust, Pollutant, Tree.
