Abstract

This research aims to explore and determine the relationship between goods and services expenditures, capital expenditures,and equity funds. It also determines both simultaneous and partial impacts of goods and services, and capital expenditures on equity funds. Sample in this research consists of 33 governmental institutions in palu city, which is selected through purposive sampling technique, or selection based on ‘jugment’. The data analyzed quantitatively with multiple linear regressions analysis. The result indicates that equity funds decreased due to spending on good and service and capital during one accounting period. Simultaneous test shows that good and service, and capital expenditure have significant  impact on equity funds in 33 govermental institutions. While partial test  evidences that espenditures partially have significant impact on equity  funds in 33 govermental institutions in palu. Coefficient determinant shows adjusted R-Square value of 0,782 that indicates that 78,20% of equity funds impacted by spending on goods and service, capital,  while the remining of 21,80% is impacted by other variables that are not studied.

Abstract

This research was about the useofactive charcoal of the banana peel (Musa normalis) as adsorbent to degrade peroxide and free faty acid of the used cooking oil. The aims of thisresearch was to determine the best rasio of active charcoal of the banana peel as adsorbent, and the best concentration of NaOH as activator to reduceperoxideand free faty acid of the used cooking oil. This research used 5 level oftreatmentswhich based on CRD, the ratio variation were 2.5, 5.0, 7.5, 10.0 and 12.5 % and the concentrations of NaOH variation were 0.125, 0.25, 0.5, 1 and 2 N. The result showed that the best ratio was occurred in the 10.0 % and the concentration of 1 N NaOH. This value indicated that the banana peel was an adsorben, which can be used inincrease quality of the used cooking oil.

Abstract

Biosurfaktan palmitin etanolamida diperoleh dari reaksi antara asam palmitat dan etanolamina dengan menggunakan katalis enzim lipase imobil getah pepaya dan pelarut organik n-heksan. Pengaruh enzim lipase dapat dianalisa dengan menggunakan katalis enzim lipase ekstrak getah pepaya yang telah diimobilisasi dan reaksi tanpa katalis sebagai pembanding. Telah dilakukan tiga variasi untuk mendapatkan kondisi optimum reaksi masing-masing adalah variasi waktu, konsentrasi enzim imobil dan rasio asam palmitat terhadap etanol amida. Dari ketiga variasi tersebut maka waktu 72 jam, 12,5% enzim imobil dan rasio 1 : 7 memberikan hasil yang optimal dan hasil dilihat dari besarnya bilangan ester yang diperoleh

Abstract

Study about the Utilization of corn cob waste (Zea mays) for Bioethanol production using immobilized yeast cells repeated used has been done. The aim of this research was to find both the ratio of sulfuric acid to corn cob wheat and the hydrolysis time in order to get the high sugars content, and to know the activity of the immobilized yeast cell for alkohol content during repeated use. It was done by apply  5 levels of surfuric acid (50%) ratio to corn cob wheat and 5 levels of hydrolysis. It was 1 : 1 (A), 2 : 1 (B), 3 : 1 (C), 4 : 1 (D), and 5 : 1 (E) based on v/b and 0,5; 1;  1,5;  2; and 2,5 hours respectively. The result showed that the best ratio of sulfuric acid to corn cob wheat was 5 : 1 (v/b), it produced the sugars content for about 41,63%. While the best hydrolysis time was 1,5 hours and it gaved 43,75% of sugars content. The sugar Fermentation was done in 48 hours. The activity of immobilized yeast cell using sulfuric acid hydrolysis product getting decreased in repeated used, and there was no alcohol producted at the fourth time of immobilized yeast cell used.
