Abstract

The objectives of this research were: to determine critical parameters and to estimate it’s shelf-life using Accelerated Shelf-Life Testing (ASLT) with Arrhenius method. Rujak seasoning that packed in plastic bottle was stored at three storage temperature 35oC, 45oC, and 55oC. Each room storage was loaded with three samples. This research was carried out for 25 days and observation was done every 5 days. The parameters observed included pH and sensory parameters, namely flavor, color, and salak aroma of the seasoning. Results showed that the critical parameter of rujak seasoning was pH and all quality parameters of rujak seasoning such as pH, flavor, color, and aroma followed first reaction order. By using extrapolation, the shelf-life of rujak seasoning packed in plastic bottle which stored at room temperature 28oC was 167 days (5,6 months).

Abstract

Broiler chicken sales in the West Manggarai Regency are still done traditionally. Traditional broiler chicken marketing is considered ineffective in the current digitalization era because many businesses have directed to the digital world, one of which is an online sales system or e-commerce. The purpose of this research was to design a system of selling broilers chicken online so that it can connect to farmers and buyers in the digital world. Broiler chicken e-commerce the system was built in the form of a website to facilitate users accessing the system without has to install applications and get free access. The system was built using Laravel framework version 5.8 and the XAMPP application as a database server. System testing used the black box testing and user acceptance testing (UAT). Black box testing focuses on the functional requirements of the software, while UAT testing focuses on non-functional requirements. Results of UAT test revealed the percentage of user acceptance of software that had been made. The results of the system testing using the black box testing method indicated that the system met the expectations of the users. UAT tests result obtained score interpretation score which value of 80.53%. This showed that the percentage of user acceptance of website-based broiler chicken sales information system in West Manggarai Regency, East Nusa Tenggara that had been built got the very good category.

Abstract

An experiment on biourine fermentation using cow urine has been carried out. The objective of this research was to optimize biourine fermentation by adding starter and palm sugar. The reseach used Completed Randomized Block Design with factorial pattern of 2 factors and 3 levels each. The first factor was starter concentrations of Rumino bacillus 0, 15, and 30 ml. The second one was weight of palm sugar added at 0, 15, and 30 g. Each treatment was repeated 3 times. Varibles observed were pH, acid, soluble solid, organic C, and total N. Results of the research indicated that starter addition of 15-30 ml and palm sugar 15 -  30 g for every 1500 ml cow urine accelerated biourine production in the fermentation stage of cow urine which was taken from simantri number 225. The fermentation process was carried out for 7 days and by adding this combination of traitment shortening the process to 5 days. This was shown by pH,total acid,and total dissolve solids value of urin which was stable after 5 days of fermentation. Concentration of 30 ml R. bacillus with the addition of 30 grams brown sugar in 1,500 ml of fermented cow urine is the optimal treatment in which the value of pH is 6, 0.5% total acid, and 3.80Brix total dissolved solids. This is supported by the standard of Permentan Number 70 with a pH value of 4-9. However, the research for C-organic and N-total has not fulfilled the standard of Permentan in which the C-organic is 6% and N total is 3-6%.

Abstract

The aims of this research were to determine the profit of each type of cut flower and to identify the types of cut flowers that should be produced to maximize profit in the diversification of flower business development. The research methods used included cost analysis, profit margin analysis, and the simplex method. The results showed that the production cost per stalk for each type of cut flower was Red Heliconia carabaea (Rp 498), Yellow Heliconia carabaea (Rp 456), Anthurium (Rp 316), Yellow Dancer (Rp 503), Hanging Chalk (Rp 578), Sexy Pink (Rp 583), Parakeet (Rp 458), Torch (Rp 496), and Onje (Rp 523), while the profit per stalk was respectively Rp 1,408; Rp 1,484; Rp 58; Rp 1,000; Rp 1,134; Rp 1,163; Rp 823; Rp 657; and Rp 429. Based on simplex method calculations, using profit margin as the objective function and production cost and market conditions as constraints, the optimal profit for business development was obtained from Red Heliconia carabaea (Rp 33,114,331), Yellow Heliconia carabaea (Rp 30,386,354), Sexy Pink (Rp 18,937,006), and Hanging Chalk (Rp 17,406,016).
