Aceh Province over the last 20 years has experienced different events that can be divided into 3 (three) phases. 1st Phase is the phase of the conflict (2000-2004), 2nd Phase is the post-earthquake and tsunami rehabilitation and reconstruction phase of Aceh (2005-2009), and 3rd Phase is the post-rehabilitation and reconstruction phase (2010-present). Events that occurred during the last 20 years are certainly likely to provide risks to community activities in the province of Aceh. One of the activities affected by the event is the construction project work. The implementation of construction works affected by events in Aceh Province over the last 20 years is highly vulnerable to risks that impact on achieving project objectives such as cost and time. This study analyzes the impact of the contractor and operational managerial risk factors on the cost and timing of construction. Data were obtained from questionnaires distributed to 15 large qualification companies in Aceh Province. Testing data is done by using the validity test and reliability test. Data that has been valid and reliable then analyzed by using Severity Index (SI). The variables of a managerial risk factor with SI to the highest cost in 1st Phase are F5 (incompetent Engineer), 2nd Phase is F3 (lack of contractor experience), and 3rd Phase is F5 (incompetent Engineer). From the operational risk factor, the highest cost SI in each phase is the G3 variable (electrical disorder). The managerial risk factors with the highest time SI in 1st Phase are F6 (lack of top management support), 2nd Phase is F5 (incompetent engineer), and in 3rd Phase is F3 (lack of contractor experience ). From the operational risk factor, the highest time SI at each phase is G3 (electrical disorder).

Lactic acid bacteria (LAB) is one of the dominant bacteria species that have an important role during spontaneous fermentation process of corn flour BISI-16. LAB are known to change the chemical structure of natural corn starch through the activity of enzyme and lactic acid produced during fermentation process. This change of structure causes the modification of physicochemical properties of corn flour. The objectives of this study were to isolate and identify indigenous LAB involved in spontaneous fermentation process of BISI-16 cornflakes. Isolation and identification of early LAB was done by isolation morphology characterization including cell shape, Gram staining, catalase test, and endospora staining. Furthermore, isolates LAB were identified by their genotypes using Polymerase Chain Reaction (PCR) method and 16S rRNA sequencing analysis. The results showed two isolates (ASN3 and ASN5) that had been isolated from corn flour during spontaneous fermentation and were grown on MRSA media having rounded colonic and creamy, rod-shaped cells, Gram (+), catalase (-), and endospores (-). The initial identification stage shows both isolates as candidate LAB. The results of the 16S rRNA sequence analysis showed both isolates were genotypically similar with Lactobacillus fabifermentans with 97% similarity for ASN3 isolates and ASN5 isolates of 98%.

Food security of a country is classified ideal if the food needs of the people have been met in terms of quantity and nutrition evenly. One alternative in achieving national food security is food diversification. Analog rice is one of the diversification of foods made from various kinds of flour as the ingredients. It is an alternative food substitute for rice. The purpose of the present study was to create and test the characteristics of analog rice made from sago flour and arrowroot flour. The parameters observed were water content, water absorption and texture. The treatment of the research was the variation of the ratio between sago flour and arrowroot flour, namely: 50:50, 60:40, 70:30, 80:20, and 90:10. This research produces analog rice with water content ranging from 11.250%-13.325%, water absorption capacity of 175%-208%, and analog rice texture from the ratio 90:10.
