Abstract

ABSTRACT The waters of sibolga is the waters are very widespread in , this area is densely populated, so there are many community activities that take place such as Transportation, Fisheries, Bathing, sand Mining and other.The purpose of this study is to determine the role of macrozoobenthos as a bioindicator of water quality in the waters of Sibolga Tapanuli Tengah, as well as determine the quality of water in the flow of the waters Sibolga physical properties, chemical has. The research was conducted from November 2019 to February 2019, the samples taken from the three research stations. From the results obtained Macrozoobenthos in the identification in this study consisted of 3 Phyla of invertebrates namely : Annelids, which consists of 2 classes, Arthropods consisting of 1 class and Molusca, which consists of 1 class. Based on the data of macrozoobenthos obtained at each research station, then the obtained value of population density, relative density and frequency of presence of that at station I the value of its highest density is Tubifex sp. with the value of the density of the population of 18,519 individual/m2, the density is relatively 25,862% and the frequency of the presence of 55,555%. off at 3. at station 2 the highest density is Tubifex sp. with the value of the density of the population of 18,519 individuals/m2, relative density 25,862% and a frequency of 55,555%. also note that the total score obtained by the method storet, namely -30, this shows that if connected with the raw water quality of class I is then classified in the waters of class III, which means that light polluted. The high total score method storet on the entire research station due to the presence of a variety of activities at each of the stations, settlements, sand mining and other activities. Where these activities produce waste, which in the end increases the content of Phosfat, COD, TSS and BOD5, thus causing the waters of the Waters of Sibolga is light polluted.

Abstract

Hotel reservation is an activity where a customer comes to the hotel to book a room and stay in a room that has been booked. Orders are made by customers, at the hotel Shades Rantaupapat the process of collecting the customers who will stay is still done manually. So that customers have to come to the hotel to make reservations directly. This reservation information system is an application that can help speed up registration or registration when at the reception. Cancellation can also be directly managed by the admin or receptionist. So as to provide other convenience in making reservations. In making this information system using a system development method in the form of a waterfall. At the time of making the programs using Visual Basic NET 2010. For databases that are used to create databases using SQL Server 2008. The application of this information system can help employees to record customers who stay overnight and manage information needs needed to support the hotel business.

Abstract

In implementing health services, puskesmas must document all actions and treatments that are given to patients in a document called Medical Records. According to Minister of Health Regulation No.269 / MENKES / PER / III / 2008 article 1 (1), medical records are files containing notes and documents about patient identities. Medical records are of good quality if the medical record is accurate, complete, trustworthy, valid and timely. One form of management in Medical Records is reporting. According to Minister of Health Regulation No.269 / MENKES / PER / III / 2008 article 1 (1), Medical Record is a file that contains notes and documents about patient identity, examinations, actions, and other services that have been given to patients. In the statement, all information about a patient has been reflected which will be made the basis for determining further actions in services and other medical actions given to a patient who comes to the community health center. The Medical Record is said to be of high quality if the Medical Record is accurate, complete, trustworthy, valid and timely. The Medical Record Installation has activities such as registration, data processing, and storage. One form of processing data in medical records is the existence of assembling activities. Assembling is an assembling activity compiling empty Medical Record forms and storing them into Medical Records, ready to use neatly arranged both in terms of quality and quality.

Abstract

This research discusses about the calculation of the division of the inheritance against his polygamous wives. the method used in this research is using a normative juridical approach, namely by using the approach to laws and regulations applicable in Indonesia as well as the norms that live in society, data obtained from secondary data, namely the rules and regulations and the material of literature. Marriage polygamy is a marriage which one of it where men have or marry more than one womenor wife. Inheritance is an integral part of a marriage where the legal heirs are divided into two principles of marriage including monogamy and polygamous marriage. As for the calculation part of the legacy of the wives of a polygamous marriage calculated from the wealth obtained from each mating that they do. The division of property in a law of inheritance i.e., by observing the position of each wife. While the right part of the wife is shared jointly by the part of the wife such as ¼ if there are no children and 1/8 if there are children.

Abstract

The present study was conducted aiming to isolate and characterize endophytic bacterial isolates with antibacterial ability, phosphate solubilization, and proteolytic activity from rhizomes of the Zingiberaceae family (Etlingera sp., Globba patens, Globba pendula, and Zingiber multibracteata). Nineteen bacterial isolates were obtained from Zingiberaceae rhizomes with isolate codes of EZS27, EZS18, EZS19, EZS25, EZS16, EZS08, EZS09, EZS13, EZS20, EZS14, EZS10, EZS11, EZS03, EZS05, EZS06, EZS43, EZS45, EZS47, and EZS28. The screening of the endophytes for antibacterial activity was done through the paper disc method. Four bacterial isolates presented antibacterial activities. EZS06 isolate inhibited the growth of EPEC (11 mm), P. vulgaris ATCC 13315 (10 mm), and L. monocytogenes BTCC B693 (9 mm). Also, EZS20 isolate inhibited the growth of S. aureus ATCC 29213 (17 mm), EZS28 isolate inhibited MRSA ATCC 43300 (8.6 mm), and EZS45 isolate inhibited S. Epidermidis ATCC 12228 (9 mm). The EZS19, EZS03, and EZS16 isolates dissolved the phosphate most effectively. Eight isolates (EZS19, EZS47, EZS27, EZS25, EZS09, EZS20, EZS45, and EZS06) showed the best protease activity. In general, our results showed that the endophytic bacterial strains can be used as a new and useful antibacterial agent since it showed antibacterial activity and chemical diversity. Furthermore, it also has the potential for exploitation in a wide variety of medical, agricultural, and industrial areas.
