The objective of this article was to study the effect of washing edamame using ozonated water to reduce residual chlorine contained in edamame through a continuous washing process. Chlorine residue in edamame was caused by the use of fertilizers and pesticides that contain chlorine compounds. The research method used was descriptive explanatory research consist of two treatment levels of ozonation time (0, 10, and 15 minutes) and ozone contact time (0, 12, 18, and 24 minutes) which were repeated twice. The residual chlorine and pesticide concentrations were calculated using the titration method. Based on research results, ozone can reduce chlorine in edamame. The lowest detected chlorine was in edamame which had been washed using ozone water with an ozonation time of 15 minutes with the amount of chlorine reduced by 56%. The longer the contact time, the greater the amount of reduced chlorine and the lower the concentration of ozone remaining in the washing water. Based on the research results, a brief conclusion that can be explained was ozone could reduce chlorine in edamame caused by fertilizer and disinfectant overuse until 50%.

In Indonesia, Hospital wastewater treatment generally use biological process followed by chlorination process. Chlorination process has a negative impact on the aquatic environment that is cause death of other microorganisms by the residual chlorine. On the other hand, ozone is more effective than chlorine in killing microorganisms and other pollutants in hospital wastewater. The objective of research is to determine the effect of contact time and dose of ozone to reduction of pollutants (BOD, COD, free Ammonia and Phenol) in hospital wastewater. The experiment was carried out using an ozone reactor containing 'packing', an ozone generator as an ozone gas supplier. The experimental material is a hospital wastewater containing BOD, COD, Phenol and Ammonia free. The experimental variables used were: Contact time (1, 2, and 3 min), Dose of ozone (10, 15, and 20 mg/ L). Experiments were done by flowing hospital waste water at the top of the reactor ozone at certain rate and simultaneously flowed ozone gas from an ozone generator in the bottom of the ozone reactor so that it contacts the fluid in counter-current to the surface of the packing material (packing) in an ozone reactor. By adjusting the flowrate of the wastewater and the height of the packing, it can be determined the amount of contact time and ozone dose. Furthermore, by measuring the amount of pollutant concentration on the influent and effluent of the ozone reactor, it can be obtained the amount of removal in the pollutant concentration of the hospital wastewater.The results showed that contact time and ozone dose influence the decrease of pollutant concentration in hospital wastewater where contact time at 3 minutes and ozone dose 20 mg/L and ozonation time 15 minutes can reduce of pollutants concentration as BOD (97%), COD (98%), Ammonia free (97%), and Phenol (96%).

The research results obtained by researchers concluded that child before obtaining care of foster parents in RPSAA has the characteristic of low emotional intelligence. Parenting patterns are applied in the RPSAA to foster care parenting is democratic. While parenting results in fostering emotional intelligence RPSAA Ciumbuleuit Bandung teenager in concluding that foster care teens have had a pretty good emotional intelligence, that is visible from how they are able to control all the feelings on him, even though there are teenagers who do not yet fully meet aspects of emotional intelligence.

Buy Back

The buy back guarantee agreement in the cooperation agreement aims to protect the bank frombusiness risks in the distribution of machine ownership financing. Buy back guarantee is defined asthe ability of the supplier as a guarantor against the bank, to "buy back" the machine object afterthe debtor is declared in default to the bank. Based on the description, the writer tries to examine theimplementation of the buy back guarantee agreement related to the distribution of machine financing,and legal remedies for the bank applying the contents of the buy back guarantee if there is default onthe debtor. The research method used in this research is normative juridical with analytical descriptivespecifications.The research was carried out through literature study, then looked at the relationshipbetween one law and another and carried out an analysis related to the application of its practice.After getting a description of the research results, the writer analyzes and draws conclusions fromthe research results obtained. Primary data collection is also carried out to support secondary data,which is obtained by documentation and bank interviews related to the machine ownership agreement.The results of the study concluded that the implementation of the buy back guarantee was carriedout in several stages, namely the stage of the debtor's statement of default, the negotiation stage,and the stage of the agreement, the application of the buy back guarantee. Apart from that, the buyback guarantee that applies to PT. BPRS XXX Bekasi, there are two types of definitions: "buy backguarantee" and "help resell" by the supplier. Legal action has never been taken by the bank whenthere is default from the debtor. The bank is more concerned about the good ethics of the supplier tobuy / help sell the machine goods. The suggestions that the writer can give include, banks must applyprudential banking principles more selectively, suppliers do not only pursue sales targets but payattention to the side of the bank so that cooperation remains well established. n addition, research isneeded regarding the perspectives of the bank, supplier and debtor in addressing the problems thatexist in buy back guarantee in more depth and breadth.

Nata de leri is one of the products produced from fermented organic white, red, black rice washing water with the addition of red dragon fruit skin extract. In javanese the rice washing water is called Leri so that the resulting nata is called “Nata De Leri”. (carbohydrates, proteins, minerals) that are carried away from the rice membrane during the washing process. So that it can be utilized by microorganisms as a medium in making nata. The addition of red dragon fruit skin extract gives color because it contains a lot of anthocyanin and also the fiber and water content is very high. The purpose of this research was to determine the organoleptic and chemical characteristics of nata. This research used a qualitative descriptive method using a 2 factor complete randomized design and the treatment given was 75% of white, red, black rice washing water concentration, The concentration of red dragon fruit skin extract 75%, 50%, and 25%. The results showed that the most preferred texture on the addition of 75% red dragon fruit skin extract was an average of 4,65, the most preferred color in the addition of 75% and 25% red dragon fruit skin extract, the aroma of the average panelist doesn’t like all the aroma of nata de leri, for the taste all the samples were liked by the panelists because of their sweet taste. While the water content and crude fiber content produced are quite high on average but do not exceed SNI.

<p><em>This article wants to know the history and development of the Mathba'ah Islamiah publisher from its early days until it disappeared from the circulation of its publishing and printing world. In the 20th century, there were many publishers and printers in Bukittinggi. This arose in response to requests for reading material from educated people connected with schools' growing bloom in several places in West Sumatra. Publishing and printing work was carried out by colonial circles and Western intellectuals and involved natives from within the Muslim faith. The research method used is the historical research method. From the research results, it was found that the publishing of Mathba'ah Islamiah was a publication founded by H.M.S Sulaiman on the advice of the elderly scholars, Syekh Sulaiman Arrasuli, Syekh Muhammad Jamil Jaho and Syekh Abbas Qadhi Lading Laweh. This publication published the works of Minangkabau clerics and books used in the Madrasas of the Old People at that time. Not only publishing books, but the Mathba'ah Islamiah publisher also printed the Koran and its translations sent to various regions in Sumatra and even reached several parts of the archipelago.</em><strong><em></em></strong></p><p>Artikel ini hendak mengetahui sejarah dan perkembangan penerbit Mathba’ah Islamiah sejak masa awal hingga hilang dari peredaran dunia penerbitan dan percetakan Tanah Air.
