Abstract

This research aims to synthesize polyurethane membrace from avocado seed oil as a source of hydrixyl (-OH) and hexametylhene -1.6-dissocyanate (HDMI) as a source of isocynate (-NCO). The oil were extracted from avocado seeds at temperature of  60-80oC for 2 hours using n-hexane solvent. The results of FTIR spectrum analysis from avocado seed oil showed that there were -OH clusters absorption on the wavelength number of 3393.819 cm-1, thus this oil can be used to synthesize polyurethane membrane. The isocyanate composition, time and temperature during synthesis process of polyurethane membrane were varied. The polyurethane membrane were moulded in petri dishes, then heated up for 48 hours on the temperature of  70oC, and finally taken out from its mould. The characteristics of the polyurethane membrane from avocado seed oil are brown in colour, homogenous, elastic, solid, transparent and shaped like a membrane. The measurements from FTIR spectrum showed that the -NCO clusters are no longer present. This condition happened because there were no more absorption in the wavelength number of  2270 cm-1 . It can be concluded that the isocyanate has completely reacted during polymerization and the curing process, thus urethane was created in the 1699,965 cm-1 absorption which was the urethane C=O clusters absorption.

Abstract

Garlic (Allium sativum) contains organosulfur compound that plays an important role as an antibacterial and antifungal activities. Ascorbic acid or vitamine C also has been show has a good activity as an antioxidant and as an antifungal. The aims of the research is to determine the effect of the combination of petroleum ether garlic extract with vitamin C against Candida albicans. Zone of inhibition testing done by Kirby-Bauer method. The results showed that the combination of petroleum ether garlic extract with vitamin C in concentration of 50% did not show an activity significantly. Meanwhile, the activity of petroleum ether garlic extract alone at concentration of 50 and 75% showed activities towards Candida albicans with a diameter of inhibition zone are 19.46 and 27.46 mm respectively.

Abstract

Penelitian ini bertujuan mengetahui aktivitas sulfur dan selenium nanopartikel terhadap cacing Steinernema feltiae (S. feltiae) dan perbandingan toksisitasnya terhadap sel neuroblastoma (neuro 2A). Sulfur dan selenium nanopartikel “aqueous nanoparticles” dikarakterisasimenggunakan Nano Zetasizer pada pH 7 dan suhu 25 C. Dalam penelitian ini uji nematoda dilakukan terhadap S. feltiae. Hasil penelitian menunjukkan bahwa sulfur nanopartikel mempunyai aktivitas yang sangat tinggi terhadap S. feltiae dengan lethal dose 50 (LD50) berkisar pada 6,99 μg/ml setelah 24 jam inkubasi. Sementara itu, live and dead assay dilakukan terhadap neuroblastoma sel (Neuro 2A cell lines). Hasil penelitian menujukkan bahwa ‘aqueous’ sulfur nanopartikel (NPS) menunjukkan aktivitas yang lebih baik dibandingkan dengan ‘aqueous’ selenium nanopartikel (NPSe) terhadap sel neuroblastoma (neuro 2A cell lines) dengan IC50 1 μg/ml.

Abstract

One very important aspect in the development of Micro, Small and Medium Enterprises (MSMEs) is the form of granting permits for carrying out business activities, which are given by the authorities to business actors. Legality in a business also has a very important role, because it is used as an indication that the business being established is feasible and running. NIB is a business identity number used by business actors to obtain business permits and commercial or operational permits. The community service activities carried out were creating Business Identification Numbers through Online Single Submission (OSS) and marketing to several small business partners, due to a lack of understanding of gadget applications and a lack of product marketing strategies in Sukamoro Hamlet, Puncu Village. The purpose of this service is to provide understanding to the public about the importance of having business legality and product marketing. The method used is observation. The number of umkm in Sukomoro Hamlet is 11 umkm, and 1 umkm does not yet have an NIB. The UMKM was pleased and succeeded in forming an NIB so that it was able to obtain an NIB legality certificate, namely the "Salsabila" banana chips business. The results obtained from this activity were an increase in product quality and customers for "Salsabila" banana chips.
