Abstract

Telenomus sp. is one of the most important biological control agents for several Hemipterous and Lepidopterous  insects.  This study was performed to determine the effect of host diets on host preference and host suitability in Telenomus parasitoid.    In this research, the hosts (Nezara viridula) was reared on the different diets, i.e. Vigna sinensis, Phaseolus vulgaris, and Indigofera suffruticosa.  The result of this experiment showed that the parasitization level of Telenomus sp was not affected by host diets.  However, host diets affected on the percentage of the parasitoid offspring. The percentage offspring was 96%, 81% and 44% from host fed on I. suffruticosa, V. sinensis,and P. vulgaris, respectively. The offspring for all of treatments was biased to female (more than 70%), however it was not affected by host diets. The developmental time for immature stage of Telenomus was also affected by host diets, it was 12, 13 dan 14 days from host fed on I. suffruticosa, V. sinensis,and P. vulgaris, respectively.  These results indicated that I. suffruticosa more suitable host diet for the development of  Telenomus progeny, which may due to more riches nutrients contain in this plant than the other plants.

Abstract

"Enbal" is one of the traditional foods from Kei Islands (Southeast Maluku Regency and Tual Town), which is made from cassava. This traditionally processed food has been known for generations. This product contains high carbohydrate but very low other nutritional values. One effort to improve the nutritional content of enbal is by the addition of fish flour to the process of fish enbal making. Round scad fish, the biggest catch result in Maluku, are used for making fish enbal. Research on round scad fish enbal has never been done before. Therefore, it is necessary to study about it, especially its formulation and nutritional value.The objectives of this study were to  determine the concentration of fish content in round scad fish enbal both chemically and organoleptically. Enbal fish with various concentration having the quality of being good with resources take the panel ranges between neutral until like. Formulations enbalbuyes is based on the method chosen by the addition of flour fish 15 %.

The research was conducted in Peuniti Banda Aceh, with the objective of identifying and assessing the realization of social integration and social conflicts that occurred among migrants, and among migrant populations "original" Peuniti which is urban slum village (slum areas). To find and assess the influence of regional origin of heterogeneous circular migrants to the possibility of social integration and social conflicts that took place in the process of social interaction. The aim of this study is to know and study the process of adaptation among migrants and between migrants with local residents, furthermore, to know and assess the social and demographic characteristics, education and economic migrants circular. Social and demographic characteristics include: age, sex, marital status and religion. Educational characteristics include: education and skills. Economic characteristics include: type of job, income, working hours and work location. Another important reason for conducting this research is to find and examine the reasons for living in Peuniti circular migrant. The selected respondents are 107 people. Methods of data analysis used method of frequency tabulation and cross tabulation. In addition, to the use of cross tabulation method is to determine the size of the effect caused by the size of the frequency and percentage. The results allegedly embodiment of social interaction is more dominant than the conflict social have a positive relationship between fellow migrants from the same area. There is also a positive relationship between bonds of different areas. Most migrants have education and low skills, age and productive work in the sector informal. Migrant prefers residing in Peuniti for reasons closer to the workplace and ease of transportation and the rent is relatively cheap hostels

Abstract

Agricultural yield was negatively impacted by salt stress throughout around the world affecting production whether it is for economic gain or subsistence. The tolerance of Acehnese local rice on salinity stress was studied with using osmotic condition in the method of in vitro germination. NaCl was applied on medium MS for the salinity stress simulation for studying the capability of the various osmotic conditions in selection of some Acehnese local rice for the tolerance of salinity stress. The objective of this research was to simulate with in vitro method the tolerance of some varieties of Acehnese local rice on salinity stress during seed germination. Sixteen varieties of Acehnese local rice was sterilized and germinated in vitro for tens days in 250 ml bottle containing 25 ml of medium MS with applying NaCl as concentration 0, 0.5, 1.0, 1.5 and 2.0 g/liter. The varieties of Acehnese local rice that used in this research are Ciherang as control variety, and Acong, Padi Mas, Aweuh, Rom Mokot, Bo Santeut, Sigudang, Bo 100, Sanbei, Sigupai, Manggeng, Sipirok, Padi Berselona, Salah Mayang Ru, Pandrah, dan Sikuneng. The results of this study showed that the tolerance of Acehnese local rice different significantly on observed viability of the seeds: seed growth rate, germination capacity, growth velocity, growth unity, and seedling fresh weight. The osmotic condition of NaCl resulted an effective method to simulate the tolerance of salinity stress for Acehnese local rice using NaCl in the method of in vitro cultivation. The solution with 2.0 g/l of NaCl that used to study the responds of Acehnese local rice to the tolerance of salinity stress was obtained as the best concentration. Thus, simulation of salinity stress condition on Acehnese local rice will become an alternative method for selection of genotype traits related to the tolerance of salinity stress for local rice in the future

Abstract

The main objective of this research is to determine the effect of beating to physical, mechanical and optical properties of the paper. The pulp that is used in this research is pulp from Oil Palm Frond (OPF). Pulping method that was carried out in this research is the kraft pulping which was undergo in 4 different conditions (20% NaOH: 20% Na2S; 20% NaOH, 30% Na2S; 30% NaOH, 20% Na2S and 30% NaOH, 30% Na2S). The beating process is carried out using PFI Mill Beater and five amounts of beating were imposed to each pulp (0, 250, 500, 750 and 1500 rotations). From the result obtained, the freeness (CSF) of the pulp was decreased against the increasing amount of beating. The optimum amount of beating is at 1500 rotations for tensile strength (5981.1 N/m), bursting strength (660.72 kPa) and folding endurance (915). For tearing resistance (730.23 mN), the optimum amount of beating is at 250 rotations. Beating also contributes to reduce the brightness and the opacity too. The result show that suitable beating stage for kraft OPF pulp is at 1500 rotations, because almost all testing give optimum or closely to optimum result at this amount of beating.

Abstract

Pegagan (Centela asiatica [L] Urban) contains alkaloid, flavonoid, saponin, triterpenoid and tannin that have antibacterial activity. Staphylococcus aureus and Klebsiella pneumoniae are most common of bacteria that cause pneumonia. This study conducted t odetermine the effect of ethanol extracts of pegagan in inhibiting the growth of S. aureus and K. pneumoniae that caused pneumonia. The type of this study is a laboratory experiment using a completely randomized design (CRD). Testing of inhibitory growth effect was measured by Kirby Bauer disc diffusion method. The results showed that ethanol extracts of pegagan at 12.5%, 25%, 50% and 75% concentrations formed inhibition zones on the growth of S. aureus, on average respectively of 7.00 mm, 9.20 mm, 13.20 mm, and 14.50 mm, whereas on the growth of K. pneumoniae, it didn’t form any inhibition zone. The results of ANOVA and Duncan (α=1%) tests showed that ethanol extracts of pegagan at all concentrations made a significant difference in inhibiting the growth of S. aureus compared to negative and positive control. The ability of ethanol extracts of pegagan to inhibit the growth of S. aureus at 12.5% and 25% concentrations categorized as no inhibitory growth effect, whereas 50% and 75% concentrations categorized as weak inhibitory growth effect. While the ethanol extracts of pegagan at all concentrations of the tests categorized as no inhibitory growth effect for K. pneumoniae. It can be concluded that ethanol extracts of pegagan inhibit the growth of S. aureus, but do not inhibit the growth of K. pneumoniae.
