Abstract

Swamp buffalo (Bubalus bubalis) play an important role in supporting the economy and social life of the community in the East Sumba Regency. The prevalence and intensity One of the diseases still a health problem in livestock, including buffalo, is parasite infection. Research on cases of parasite infection in buffaloes in the East Sumba Regency has not been widely reported. Therefore, this study was conducted to identify the parasites that infect the buffalo as well as to measure the prevalence and infection rates. The coprological examination of 105 samples of swamp buffalo feces from the East Sumba Regency was conducted in this study. The simple flotation and the modified McMaster method were used to identify and measure the degree of infection of Nematode, Cestode, and protozoan oocyst, while the modified Danish Bilharziasis Laboratory (DBL) method was used to detect the presence of Trematodes. The results showed that 67 out of 105 buffaloes (63.81%) had parasite infections, which were caused by a single (44.76%) and mix infection (19.05%). The prevalence of infection with Nematodes, Trematodes, and Protozoan oocysts in males (73.33%) was much higher than in female (60.00%) buffalo; nevertheless, the chi-square test results showed that sex was not associated with the prevalence of parasites infection cases (p>0.05). Age was a risk factor that had a significant effect (p<0.05), with the young age group having the highest odds ratio (OR) value (5.80), followed by the age group of the calf (3.10), and pre-weaned calf (2.98). The highest to lowest infection rates were observed in Cestodes (547.03 EPG), followed by Protozoa (220.70 PG), Nematodes (84.75 EPG), and Trematodes (2.18 EPG). The present study shows that buffalo in East Sumba Regency are infected with several parasites, so control must be made to prevent losses due to the infection.Keywords - Bubalus bubalis, East Sumba, fecal examination, gastrointestinal parasites, the prevalence

Abstract

This research is based on the fact that many domestic sugar industries operate inefficiently and have low productivity, which is seen when compared to other countries such as Thailand, India and Australia. This study aims to identify and analyze problems along the flow of the white crystal sugar production process that cause waste and then make suggestions for improvements to reduce existing waste to increase cost efficiency in the production process. The national sugar factories generally have a basic problem, namely the low level of factory efficiency, which causes a lot of waste along the flow of the production process. The right concept for solving this problem is the implementation of the Lean manufacturing method, where this method focuses on efforts to reduce waste along the flow of the production process by making continuous improvements. The research begins with a literature study and field study and then conducts observations, analyzes, brainstorms, extracts and collects data from each work unit. The first stage begins with the define which will identify all forms of waste along the production process flow, measure to determine the most critical waste, analyze to identify the factors that cause waste in the production process, improve to carry out improvement plans, and reduce waste that occurs in the production process, and control as an evaluation of improvement results. The efficiency of the production process before the improvement is 78.7%, with improvements expected to increase production efficiency by 87.0% or an increase of 8.3 points.Keywords - Lean Manufacturing, DMAIC, Value Stream Mapping, Waste, Production Efficiency

Abstract

Dekke Na Niura is a typical traditional food of Batak Toba tribe which is made from fermented carp. Dekke Na Niura can act as a source of probiotics because it contains good microorganisms, namely Lactic Acid Bacteria (LAB). Several types of LAB are known synthesize exopolysaccharides (EPS), which are polysaccharide polymers considered important for health. Therefore researchers want to know whether dekke na niura can act as functional food evidenced by the presence of LAB and its potential to produce EPS. The presence of bacterial isolate on dekke na niura was detected by dilution series-pour plate method on MRSA (deMan Rogosa and Sharpe Agar) medium, then confirmed as LAB by morphological and biochemical characterization. The isolates believed to be LAB were then tested for their potential to produce EPS. The results showed that in dekke na niura, LAB isolates were found by UB1, UB2 and UB3 and then all of them identified as Lactobacillus. The three isolates showed the potential for EPS production with a weight ranging from 2490-3490 mg/L. This weight is known to be greater than the weight of EPS produced by commercial LAB isolates.Keywords – Carp, Dekke Na Niura, Lactic Acid Bacteria, Exopolisaccharides
