Clove (Syzygium aromaticum L.) is one type of spice plant that has high antioxidant content because of the high eugenol compounds. However, iso-lating these bioactive compounds require a significant amount of biomass. A known alternative solution to overcome the problems is through the utiliza-tion of endophytic bacteria in clove leaves. Endophytic cloves leaf bacteria can be a good antioxidant resource. Endophytic bacteria are bacteria that grow in plant tissues that is not pathogenic, which can replace these plants. The aim of this study is isolating endophytic bacterial from clove leaves, screening endophytic bacteria, determining potential endophytic bacteria as producer antioxidant compounds, and identifying potential isolate using 16S rRNA. This study used endophytic bacteria isolated from clove leaves (Syzygium aromaticum L.). Antioxidant activity determined using DPPH method. It was founded 7 isolates of endophytic bacteria namely WDY1, WDY2, WDY3, WDY4, WDY5, WDY6, and WDY7. The isolate WDY6 shows the highest antioxidant activity. WDY6 isolate is identical to Staphylococcus sp. with a 100% similarity. Staphylococcus sp. has the highest antioxidant activ-ity in the stationary phase. The content of chemical compounds from WDY6 isolates is pyrazine that belongs to alkaloids.

This study aims to determine: The Effect of Price, Product Quality and Service Quality on Customer Satisfaction at Indoprint Kaltim Mandiri Samarinda Printing. The sample was taken using the Slovin formula with a total of 97 respondents. The data collection technique uses a questionnaire, the data presented is data obtained from the respondents' answers, using arithmetic tools with the SPSS version 22 program and analyzing the value of multiple linear regression. The results of this study indicate the variable Price (X1), Product Quality (X2), and Service Quality (X3) have a positive effect on Customer Satisfaction (Y), but only the Price variable has a significant result and is the most dominant. The closeness of the relationship between Price, Product Quality and Service Quality to Consumer Satisfaction in choosing the Indoprint Kaltim Mandiri Samarinda printing company is 0.922, with the value from the interpretation table correlation coefficient 0.80 - 1.00. This is able to explain that there is a very strong relationship between Price, Product Quality and Service Quality on Customer Satisfaction in choosing the Indoprint Kaltim Mandiri Samarinda printing company. Price, product quality and service quality affect consumer satisfaction by 85.00%. These results indicate that 85.00% of which affects customer satisfaction by the factors of price, product quality and service quality, while 15.00% is influenced by other factors not examined by this study.

The implementation of inheritance distribution to the indigenouspeople of Nias in Harefanaese Village experienced a shift from the customary rules that should be,where currently there are several families who have given inheritance to their daughters even though itis in the form of small items but there are also those who have given inheritance in the form of land.Even though there are customary provisions that regulate inheritance issues, there are stillproblems/conflicts that occur due to the implementation of inheritance distribution. The objectives ofthis study are as follows: First, to determine the implementation of inheritance distribution toindigenous peoples in Harefanaese Village, North Nias Regency, Second, to determine the settlement ofinheritance distribution disputes among indigenous peoples in Harefanaese Village, North NiasRegency. This research is a sociological law research. That is, this research directly observes thespaciousness, the research location is Harefanaese Village, North Nias Regency. The samplingtechnique is a purposive sampling technique. The research data collection uses primary data andsecondary data. The data collection technique in this study is interviews and literature review and isconcluded by qualitative. Can be drawn; first, that the implementation of the distribution that took placein Harefanaese Village, experienced many shifts from the customary rules that should have been, wherecurrently there are several families who have given inheritance to their daughters, secondly, thesettlement of inheritance distribution disputes to indigenous peoples in Harefanaese Village, North NiasRegency, namely by holding consultations.Keywords: Inheritance-Customary-Dispute Resolution
