Abstrak: The effect of packaging and temperature storage on color quality attribute of potato fluor was investigated. Color quality is measured by the value of brightness (L*) using Chromameter Minolta CR-200, browning index, whiteness index, enzyme polyphenol oxidase activity, water content of starch during storage and organoleptic quality. Estimation of shelf life was measured using the method ASLT (Accelerated Storage Studies) semi-empirical Arrhenius equation in the varied storage temperatures (20oC, 30oC, and 40oC) and two types of packaging (polypropylene and low density polyethylene). It was found that shelf life of potato flour in lower temperature storage resulted in better color retention. Potato flour shelf life based on the parameters of brightness and browning index is at a temperature of 30oC storage box that is 4 month 24 days. Packaging and storage methods had obvious effect on the product quality.

Abstrak: The packaging has an important role to prevent and delay the decay of food. The used packaging will affect the chacteristic of packed shallot powder, the physically and chemically change is caused by chemical migration from packaging, aroma change, color change, and texture change due to water vapor and oxygen. These conducted research was designed to study and explore changes in physical dan chemical characteristics of shallot powder in packaging for storage in an effort to obtain a longer shelf life. Test parameters used in this study were color, water aktivity, moisture, ash content, concentration of total phenolics, and antioxidant activity. There were three conditions to store samples, i.e 20 oC, 30 oC, and 40 oC for 32 days. The results of this research of three packaging and temperature treatments during storage, has showed the increase and decrease of lowest slope on alumunium foil coated polypropylene vacuumed as parameters. iii On colorimetric measurement, water activity assay and water content assay showed the slope increase as 0.0942, 0.0042 and 0.0261 at temperature 20 oC, 30 oC, and 30 oC consecutively. The ash measurement, total phenolic concentration, antioxidant activity and inhibition precentation each has slope decrease as -0.0094, -4.2188, -0.9557 and -0.2924 on 30, 20, 30 and 30oC consecutively.

Judul: Peranan Pemimpin Informal dalam Menggerakan Partisipasi Masyarakat  untuk Pembangunan Desa
Abstrak: Pendekatan pembangunan yang banyak diterima para ahli adalah pendekatan dari bawah ke atas (bottom up) yang berarti bahwa dalam pembangunan diperlukan keikutsertaan rakyat. Keikutsertaan tidak hanya pada tahap merencanakan pembangunan, akan tetapi juga ikut dalam melaksanakan, bahkan sampai pada menilai hasil-hasil pembangunan (Cohen dan Uphoe 1977; Dusseldorp, 1981; Slamet, 1993). Agar rakyat yang berhimpun dalam kelompok-kelompok dapat ikut serta, mereka harus memiliki sejumlah kualifikasi yang diperlukan untuk itu.
