Abstract

This paper aims to determine the type of negative glass the archive of Memory of The World, which is officially called the Borobudur Conservation Archive by UNESCO. The method used is by observing the storage Memory of the World at the Borobudur Conservation Office, looking at the negatives physical appearance of the glass directly to determine its characteristics based on literature studies. In addition to seeing the character direct with the eyes, SEM analysis was carried on surface samples and negative glass slices, FTIR analysis also SEM-EDX analysis were used to confirm the initial hypothesis which predicts that this glass negative contains silver and gelatin as a binder. The results obtained are that it is true, the glass negatives of the 'Memory of the World' archive collection at the Borobudur Conservation Office contain silver and gelatin as binders, so this type of glass negatives is gelatin dry plates. The identification of negative glass is necessary to determine the next conservation. However, this paper does not cover how the proper conservation and storage for glass negative collection archives. Therefore, another research is needed to discuss how to conserve negative glass in the Borobudur conservation archive collection.  ABSTRAKTulisan ini  adalah tentang  proses untuk mengetahui karakteristik  film kaca negatif pemugaran Candi Borobudur. Film kaca negatif tentang pemugaran candi Borobudur  merupakan bagian dari arsip Borobudur yang  telah ditetapkan oleh UNESCO sebagai  arsip Memory of The World. Metode yang digunakan untuk mengetahui karakteristik film kaca negatif yang diterapkan adalah dengan melakukan observasi fisik secara langsung dan dengan  membandingkan  dengan ciri-ciri yang dideskripsikan berdasarkan studi pustaka. Selain melihat cirinya secara langsung dengan mata, dilakukan pula analisis mikroskopis untuk mengetahui komposisi  kimianya dengan  menggunakan SEM pada sampel permukaan dan irisan negatif kaca dilanjutkan dengan  analisis FTIR dan analisis SEM-EDX yang digunakan untuk memastikan adanya kandungan perak dan gelatin sebagai binder (pengikat).  Hasil analisis  memastikan bahwa   komposisi pada film kaca yang diamati  mengandung perak dan gelatin sebagai pengikat (binder). Jenis  film film kaca negatif dengan karakteristik  seperti ini dikenal dengan film kaca negatif  ini gelatin dry plates. Mengetahui karakteristik film negatif kaca sangat diperlukan untuk menentukan langkah-langkah konservasi yang diperlukan selanjutnya. Tulisan ini merupakan. bagian dari  penelitian untuk menentukan konservasi preventif dan interventif terhadap film kaca negatif  Memory of the World  tentang pemugaran Candi Borobudur yang harus dijaga kelestariannya

Abstract

This research aims to determine the effect of parameters on characteristic and increase stability; determine the optimum conditions to get the best nanoemulsion characteristic in the form of the smallest droplet size; find out the effectivity to inhibit Aspergillus fumigatus growth and to kill Lichens. The nanoemulsion formulation was made by using Spontaneous Emulsification of Low Energy method and it was designed by Taguchi statistical method. The parameter of analysis are organoleptic, pH, thermal stability test, freeze-thaw cycle, mechanical stability test, turbidity, polydispersity index (PdI), and particle size test. The antifungal test was carried out by applying nanoemulsions in a laboratory scale to Aspergillus fumigatus and in natural cultures by spraying nanoemulsions directly on lichen in Borobudur Temple rocks off. Nanoemulsion was successfully obtained with droplet sizes of 13.40-28.97 nm. The SNES ratio and the stirring rate had an effect on resulting nanoemulsion, while the stirring time had a less significant effect. The optimum conditions for making nanoemulsions were obtained which resulted in the best composition in a form of the smallest droplet size (13.11 nm with PdI value of 0.337), namely at SNES ratio 1:8:1, time of 5 minutes, with stirring speed of 2800 rpm. This formula resulted in a minimum inhibitory concentration against Aspergillus fumigatus growth as an estimate of lemongrass oil. Nanoemulsion with a minimum concentration of oil 2.5% was effective to kill lichens and inhibit the growth of new lichens.

Abstract

This research attempts to know diversity of the moulds found in the biodeterioration process of Pawon Temple stone and identifying the type of damage caused by the moulds in the biodeterioration process of Pawon Temple stone. Survey sampling of Pawon Temple rocks based on the conditions: damp, weathered, cracked, and there is a yellowish-white crust. Sampling is done by swab technique using sterile cotton bud and scraping technique using scalpel. Identification of macroscopic and microscopic mold with profile matching method based on the book Pengenalan Kapang Tropik Umum, Descriptions of Medical Fungi, Identification of Pathogenic Fungi. The identification finds six genus are Penicillium (13%), Paecilomyces (59.4%), Mucor (15.9%), Stachybotrys (2.8%), Aspergillus (4.3%) and Cladosporium (2.8%). The genus of kalag in Pawon Temple is based on the search of libraries and journals potentially as agents of color formation, exfoliation of rocks and formation of postules and alevol.
