Advancements in information technology are driving companies to enhance efficiency in data management, including in the field of human resources. PT Kreasijaya Adhikarya previously relied on manual reporting processes using physical documents, which led to various issues such as delays, inaccurate records, and difficulties in data access. Therefore, the development of a more modern, structured,…
An effective and efficient outpatient registration system is a crucial element in improving the quality of healthcare services. However, many healthcare facilities still rely on manual processes, which often lead to long queues, service delays, and disorganized patient data management. This study aims to develop a web-based outpatient information system focused on patient registration and docum…
White jabon fruit (Anthocephalus cadamba Miq.) has the potential to be used as a biosorbent because it contains cellulose, whose adsorption capacity can be enhanced through activation. Activation in this study used NaOH and was combined with humic compounds from peat water, such as humic acid, which is expected to increase the surface area and multiply the active sites on the biosorbent. This s…
The white jabon fruit (Anthocephalus cadamba Miq.) combined with humic acid extracted from peat water, is believed to hold potential as a biosorbent capable of removing various dyes, including Safranin O. This fruit was selected due to its relatively high cellulose content, making it suitable for biosorption applications. The aim of this study is to determine the adsorption capacity and efficie…
White jabon fruit powder (Anthochepalus cadamba Miq.) combined with humic acid from peat water has the potential to be used as a biosorbent in absorbing Crystal Violet dye. Jabon puith fruit is used as a biosorbent because of the cellulose content contained in the jabon fruit itself. The combination with humic acid aims to increase the active sites of the biosorbent in absorbing Crystal Violet …
White jabon fruit (Anthocephalus cadamba Miq.) is one of the biosorbents that has the potential to adsorb methylene blue dye because it has high cellulose content. The ability of white jabaon fruit powder can be improved through activation. Activation using NaOH is expected to increase the surface area and multiply the active sites on the white jabon fruit biosorbent. This study aims to determi…
Acacia bark powder (Acacia crassicarpa) can be used as an adsorbent because it contains cellulose, hemicellulose and lignin which play an active role in the adsorption process. This study aims to determine the contact time, stirring speed and optimum temperature of Rhodamine B dye adsorption by acacia bark powder (Acacia crassicarpa). The method used was adsorption method using batch system. Ad…
Hydrazone compounds belonged to the azomethine group, characterized by a distinctive chain (-NHN=CH-). As analogs of Schiff bases, hydrazones exhibited promising pharmacological properties, including potential anticancer activity. This study aimed to synthesize the hydrazone compound, (E)-2-((E)-1-(naphthalen-2- yl)-3-(4-nitrophenyl)allylidene)hydrazine-1-carboxamide and to evaluate its antican…
Acacia bark powder (Acacia crassicarpa) is a biomass that contains cellulose, lignin and hemicellulose as active sites of adsorbent. The purpose of this study was to determine the adsorbent dose, pH and optimum adsorbate concentration as well as the adsorption isotherm model of Rhodamine B by acacia bark powder (Acacia crassicarpa). The method used in this research is batch system adsorption.…
Abundant durian peel waste can cause problems in the environment. Durian peel contains chemical compounds in the form of cellulose, lignin and starch so that it can be used as raw material in the manufacture of activated carbon. In this study, chemical activation using with KOH was carried out followed by physical activation using a furnace with a comparison between the use of air (atmosphere) …
Durian peel waste can be utilized as a source of activated carbon because it has a high cellulose content of 50-60%. This utilization can reduce the amount of durian peel waste and the negative impact on the environment. In this research, a comparative study of physical activation using a furnace with air and a furnace supplied with N2 gas was conducted. The synthesis of activated carbon began …
The members of Zingiberaceae have aromatic rhizomes that are widely used in traditional medicine. The histochemical characteristic of rhizomes can be used as taxonomic marker. This sudy aims to provide data on the histochemical character of rhizomea of five genera of Zingiberaceae member in Pekanbaru Riau that have taxonomic value. The histochemical was carried on amylym, lipids, alkaloids, fla…
The primary source of heavy metal Pb pollution in the environment, which significantly affects water quality and soil engineering properties, is waste from automotive workshops. Bacteria isolated from Pb contaminated environments have shown tolerance to Pb and the ability to accumulate or reduce Pb heavy metal content. This study aimed to isolate and characterize indigenous Pb tolerant bacteria…
Rice production in Indonesia remains relatively low, partly due to suboptimal fertilization practices. One alternative that can be used is biofertilizer, which contains live microbes that help supply essential nutrients needed by rice plants, such as nitrogen (N), phosphorus (P), and potassium (K). This study aims to select endophytic bacteria from sea ferns originating from Meranti based on th…
Microbial infections caused by pathogenic microbes have become an increasingly serious global health concern, particularly due to the rise of microbial resistance to antibiotics. An alternative solution is being explored by investigating bioactive compounds from endophytic fungi of mango macang (Mangifera foetida), which are capable of producing secondary metabolites with potential antimicrobia…
