Abstract

This research aims to know antioxidant activity, total phenolic, nutrient, and screening phytochemistry compounds of S. hystrix dry powder. Water extract from the dried sample of brown algae (S. hystrix) was prepared and examined for its phenolic compounds. The amount of total phenolic compounds in water extract was about 11.43 g Gallic Acid Equivalent (GAE)/100 g of dry basis sample, as measured by using Folin-Ciocalteu method. The antioxidant activity (Radical Scavenging Activity/RSA) of BHT as a standard was high about 96% inhibition of radical DPPH with 1 mg dry sample/ml solvent. The IC50 of the BHT was 0.227 ± 0.001 mg of dry sample/ ml solvent. While the radical activity (RSA) of S. hystrix dry powder was about 65.28% at 1 mg dry sample/ml solvent. The IC50 of S. hystrix dry powder was 0.616 ± 0.005 mg of dry sample/ml solvent. Nutrient contents and bioactive compounds of dry powder S. hystrix were balanced to support antioxidant activity of the sample. The results suggest that this alga is a potential source of natural antioxidant.

Abstract

The study aimed to determine the effect of pH and temperature on N-Acetylglucosamine (NAG) formation from shrimp shell chitin by Serratia marcescens PT-6 fermented in chitin broth medium. Parameters examined on NAG formation include bacteria growth, chitinase activity (U/ml), and NAG concentration in medium (mg/ ml). Bacteria growth was measured by turbidity (OD600), while chitinase activity and NAG concentration in the medium were analyzed quantitatively by colorimetric assay. The variation of initial pH examined in chitin broth medium was 5; 6; 7; 8, while temperature variation was 30°C; 37°C; dan 40°C. The results show that maximum concentration of NAG formed by Serratia marcescens PT-6 was 33.86 µg/ml on day-3 of fermentation, at pH 7 and temperature of 30°C. Chitinase activity on the same day was 0.002 U/ml, while OD600 value of the culture was 0.42 indicating the bacteria were in the log phase. This research implies that Serratia marcescens PT-6 is potential to be optimized further for the bioconversion process of NAG from shrimp shell waste through an enzymatic method by modifying its culture condition.

Abstract

This paper aims to discuss the history of Acehnese wars and the progress of peace in Aceh after the signing of the Memorandum of Understanding between the Aceh Freedom Movement, or Gerakan Aceh Merdeka (GAM), and the Republic of Indonesia in Helsinki on August 15th, 2005. Prior to this, Aceh was a tense region and home to the longest armed conflict in Southeast Asia – underway since 1982. The people of Aceh were fighting to realize the concept of self-independence. However, the movement came to a stop when the devastating tsunami hit Aceh on December 26th, 2004. The purpose of this paper is to discuss the root of Acehnese wars. The paper will provide the current political, social, economic and cultural achievements since Aceh entered into a new chapter of peace. Using qualitative approach, the theory of inequality and conflict and Fanon’s ideas, this paper offers a comprehensive perspective on learning from Aceh wars and conflicts. This study found that the motive of wars in Aceh can be divided from group motive, private motivation, failure of social contract and environment scarcity. Moreover, the research confirms that social and economic progress in Aceh has not been as successful as its political achievements. Furthermore, in terms of culture, progress has been ambiguous. This paper aims to provide a better understanding of how to maintain peace in Aceh by addressing social, political, economic and cultural issues with the goal of attaining prosperity and well-being for the people of Aceh.

Abstract

Thyroxine hormone (T4) was one of the hormones related to metabolism rate. Animal transportation could be stressor interfering metabolism. Sargassum crasifoium was one of brown algae species that contained some important nutrients and also flavonoids. The study aimed at finding out the effect of the Sargassum on the decrase in thyroxine hormone and body weight loss. It used 9 Javanese Randu goats that were classified into 3 treatment groups. Group I served as control, Group II was treated with 450 mg/kg BW of Sargassum estract and Group III was treated with vitamin B1. All of the goats were transported for 12 hours using pickup truck at the speed of 60 km/hour. Blood samples were drawn before the transportation, during loading, 6 hours after the transportation and at the end of the transportation, while the body weight of the goats was weighed before and after the transportation. The results of the study showed that the T4 hormone decreased in the Group I and increased in the Group III during the transportation, while it was stable in the Group II. The biggest percentage of the body weight loss took place to the Group III (0.13%), while the smallest percentage took place to the Group II (0.063%). Statistical analysis showed that the Sargassum extract did not have any significant effect (p>0.05) on both the thyroxine hormone and the body weight loss during the transportation. Based on the results of the study it could be concluded that the Sargassum extract could stabilize the thyroxine hormone during the transportation so that it could prevent the body weight loss

Abstract

Highlight ResearchThe chitinase production by Streptomyces sp. PB2 was studiedThe critical medium component for chitinase production were identifiedThe optimum medium composition for chitinase production was obtainedMedium optimization improved chitinase production by 6-fold increase in activityAbstractChitin is a polysaccharide compound composed of N-acetylglucosamine (NAG), which is linked by β-1,4-glycoside bonds. In producing NAG from chitin, enzymatic method using chitinase offer advantages compared to chemical degradation. Streptomyces sp. PB2 is a good candidate of chitinase producer which was previously isolated from shrimp pond sediment. However, optimization of chitinase production by Streptomyces sp. PB2 is required for large-scale production of this enzyme. This study aimed to find the optimal medium composition to increase the chitinase enzyme activity of Streptomyces sp. PB2 using the Response Surface Method. Initial screening was done to determine additional carbon and nitrogen sources in colloidal chitin broth suitable for increasing chitinase activity. Optimization of the medium composition was conducted using the Plackett-Burman design to determine the critical components in the colloidal chitin broth medium and continued by Box-Behnken model to optimize the concentration of the medium components. Chitinase activity was obtained by measuring the amount of reducing sugar (NAG) released from enzymatic reaction using DMAB reagent by means of spectrophotometer. The medium components showing high contribution in increasing chitinase activity were K2HPO4, colloidal chitin and peptone, with the confidence level value of 0.66, 0.48, and 0.38, respectively. The Box-Behnken model analysis shows that the combination of K2HPO4 0.007 g/ml, colloidal chitin 1.5 g/ml and peptone 1.5 g/ml in colloidal chitin broth are the optimal medium for Streptomyces sp. PB2, resulted in chitinase activity of 0.0125 U/ml. The increase of 6-fold in chitinase activity was achieved in this study.

Abstract

This article aims to discuss the development of ancient Muslim settlements on the west coast of Aceh based on the findings of Islamic gravestones at the Binanga site in Subulussalam City, Aceh. This site is very unique, it is located inland and right on the banks of the Singkel River, which is connected to the highlands of Sumatra. There are 131 Islamic gravestones, and their shapes vary greatly. The results of the morphological analysis show that the gravestones were divided into two groups: Aceh gravestones (batu Aceh) and Barus gravestones (nisan Barus). There are no biographical inscriptions carved on the gravestones, however, the morphological analysis shows that these gravestones date from the 18th to 19th centuries AD. These tombstones indicate that Muslim communities began to settle permanently in the interior of Aceh's west coast in the 1700s. The emergence of these settlements is related to the migration of people from the highlands of Sumatra to the west coast of Aceh, which was motivated by the development of international trade centered in Singkel and its surroundings since the 18th and 19th centuries AD. Thus, the tombstone on this site is very important because gave the clear picture to understand the emergence of Muslim settlements on the west coast of Aceh in the past.
