This study aims to investigate attributes of tempeh desired by consumer households, consumers satisfaction levels on tempeh, the pattern of tempeh demand, and factors affecting tempeh demand in Bandar Lampung City. This study is conducted in Bandar Lampung City. Data is collected in December 2016 to February 2017. The population in this study is household in Bandar Lampung City. The samples employed in this study are 75 households chosen by multistage random sampling method. The results showed that tempeh attributes  wanted by consumer households were cheap price, good taste, unique looks, good packaging, hygienic tempeh, quality standard, containing good nutrients, and accesibility location to purchase tempeh. Consumer households in Bandar Lampung City were satisfied by tempeh products. Tempeh demand patterns by consumer households in Bandar Lampung City were as follows: the average of tempeh purchases by household was 1,600 grams per week and the average of purchase frequency was 1.72 times per week. The total of tempeh consumption was 66.67 percent processed by frying, mostly be purchased at the market. Affecting factors on tempeh demand were price of tempeh, vegetable oil, wheat flour, and eggs.Key words: demand, consumer satisfaction, tempeh

The Stability

The most common method of biodiesel production is base catalyzed transesterification where alkaline materials, such as potassium hydroxide, are used as a catalyst. This paper presents a study of factors affecting biodiesel production from low free fatty acids (FFA) content waste vegetable oil through base catalyzed transesterification as well as the optimum reaction conditions. The optimum conditions were found to be a time of 60 min, catalyst loading of 1% of oil mass, mixing speed of 400 rpm and temperature of 65 °C. It also introduces a kinetic study of this reaction to determine the best model to fit the experimental data. First order model was found to be the best one to fit the early reaction stages while the second order model was the best to describe reaction kinetics in later stages. The stability of produced biodiesel was studied through determination of acid value and viscosity of stored biodiesel along three months.

In 1934 Hume-Rothery, Mabbott and Channel-Evans discussed the factors affecting the formation of primary solid solutions in silver and copper, and concluded that the predominant factors were the atomic diameters and valencies of the solvent and solute elements. In a later paper (Hume-Rothery and Raynor 1938) it was shown that the same considerations applied to the formation of solid solutions in magnesium, provided that due allowance was made for the highly electropositive nature of this metal. In the case of copper and silver alloys, where general valency effects are marked (Hume-Rothery et al . 1934), Hume-Rothery, Lewin and Reynolds (1936) carried out an investigation of the mean lattice spacings of primary solid solutions of cadmium, indium, tin and antimony in silver, and of zinc, gallium and germanium in copper. It was found that, to a high degree of accuracy, equal percentages of cadmium, indium, tin and anti­mony expanded the lattice of silver by amounts proportional to 2 : 3 : 4 : 6 respectively. Zinc, gallium and germanium in equal atomic concentration in copper expanded the copper lattice by amounts proportional to 3 : 4 : 4.8. These factors have been confirmed by Owen and Roberts (1939) and shown also to apply at high temperatures. The factor for germanium in copper was, however, given as 5.
