Published: August 2021

В данном исследовании была разработана методика синтеза катализаторов на основе цеолитов типа ZSM-5 с различным соотношением Si/Al и количеством кислотных центров, модифицированных оксидом вольфрама (VI). Синтезированные катализаторы были охарактеризованы и протестированы в реакции превращения моносахаридов (фруктозы и глюкозы) в 5-гидроксиметилфурфурол и левулиновую кислоту. Было показано, что введение в состав цеолитов ZSM-5 частиц оксида вольфрама приводит к заметному увеличению количества активных кислотных центров на поверхности катализатора, играющих важную роль в реакции дегидратации моносахаридов. В результате модификации заметно возросла каталитическая активность цеолитов. Результаты исследования показывают перспективность использования цеолитов типа ZSM-5, модифицированных оксидом вольфрама (VI), для конверсии биомассы в платформенные химические соединения.
In this study, a method was developed for the synthesis of catalysts based on zeolites of the ZSM-5 type with different Si/Al ratios and the number of acid sites modified with tungsten (VI) oxide. The synthesized catalysts were characterized and tested in the reaction of converting monosaccharides (fructose and glucose) into 5-hydroxymethylfurfural and levulinic acid. It was shown that the introduction of tungsten oxide particles into the composition of ZSM-5 zeolites leads to a noticeable increase in the number of active acid sites on the catalyst surface, which play an important role in the dehydration reaction of monosaccharides. As a result of the modification, the catalytic activity of zeolites has noticeably increased. The results of the study show that the use of zeolites of the ZSM-5 type, modified with tungsten (VI) oxide, is promising for the conversion of biomass into platform chemical compounds.

С помощью методов УФ спектроскопии, динамического светорассеяния (ДСР) и сканирующей электронной микроскопии (СЭМ) в водных растворах L-цистеина и N-ацетил-L-цистеина (НАЦ) с нитритом серебра (AgNO) при концентрации от 0.001 М до 0.025 М и различных соотношениях исходных компонентов изучены процессы самоорганизации, приводящие к образованию гидрогеля. Установлено, что для растворов на основе L-цистеин и AgNO (цистеин-серебряный раствор - ЦСР) с концентрацией исходных компонентов 0.025 М и выше образуются устойчивые гидрогели, содержащие наночастицы серебра (НЧС). В то же время, в растворах на основе НАЦ и AgNO гели и НЧС не формировались. Определены закономерности и условия, влияющие на процесс образования геля, что позволило предложить механизм гелеобразования в ЦСР.
Using the methods of UV spectroscopy, dynamic light scattering (DLS) and scanning electron microscopy (SEM) in aqueous solutions of L-cysteine and N-acetyl-L-cysteine (NAC) add silver nitrite (AgNO) at different concentration from 0.001 to 0.025 M the processes of self-organization leading to the formation of a hydrogel have studied in various ratios of the initial components. It has found that for solutions based on L-cysteine and AgNO (cysteine-silver solution - CSS) with a concentration of initial components of 0.025 M form stable hydrogels containing silver nanoparticles (SNPs). At the same time, solutions based on NAC and AgNO are unable to form gels and SNPs. The regularities and conditions influencing the process of gel formation have been determined, which made it possible to propose a mechanism of gelation in the CSS.

Published: August 2021

The forest inventory technique by applying remote sensing technology has become a new breakthrough in technological developments in forest inventory activities. Unmanned Aerial Vehicle (UAV) imagery with camera sensor is one of the inventory tools that produce data with high spatial resolution. The level of spatial resolution of the image is strongly influenced by the flying height of the UAV for a certain camera’s focus. In addition, flight height also affects the acquisition time and accuracy of inventory results, although there is still little research on this matter. The study aims to (a)evaluate the effect of various flying heights on the accuracy of tree height measurements through UAV imagery for every stand age class, (b).estimate the trees diameter and canopy cover for every stand age class. Stand height was estimated using Digital Surface Models (DSM), Digital Terrain Models (DTM) and Orthophoto. DSM and DTM were built by converting orthophoto to pointclouds using the PIX4Dmapper based on Structure From Motion (SFM) on the photogrammetric method to reconstruct topography automatically. Meanwhile, the tree cover canopy was estimated using the All Return Canopy Index (ARCI) formula. The results show that the flight height of 100 meters produces a stronger correlation than the flying height of 80 meters and 120 meters in estimating tree height, based on the high coefficient of determination (R2) and the low root mean square error (RMSE) value. In addition, tree canopy estimation analysis using ARCI has a maximum difference of 9.8% with orthophoto visual delineation.

The objective of this study is to obtain the data and information related to the potential of income increase gained from the visitors’ perception and behavior towards Serulingmas Wildlife Recreation Park (TRM) in order to optimize many resources owned through tourism service innovations offered to visitors. The data were collected by delivering questionnaires to 150 visitors. The data collected included characteristics, motivations, and perceptions of visitors toward animal collection which were categorized into four, i.e.knowledge about animal, visitor behavior towards animals, collection rating, and animals` condition. Moreover, the condition of facilities in Serulingmas TRM was also evaluated. Furthermore, the management will be able to find the recent condition of collection animals based on the current information obtained from visitors. Thus, the information could be used to improve the management and increase the attractiveness about the animals for visitors. The results showed that seeing animals was the most popular activity for visitors and tiger was the favorite animal selected by the visitors of Serulingmas TRM. Visitors had a perception that the existence of Serulingmas TRM could increase knowledge and positive behaviors towards animals supported by a good and attractive cage arrangement, healthy animal condition, good facilities and service condition. Moreover, the visitor's interest in seeing animals along with the willingness of visitors to pay the entrance fee by adding the animal attraction could increase the income estimation by 36.67% started from 2019 only if the management increased the entrance fee to Rp25,000.00 (based on visitors` Willingness to Pay value). The improvement of attraction that pays attention on the visitors` desire and needs by also considering animals` welfare can support a sustainable conservation agency.

Mount Merapi’s eruption has caused damage to the forests in the Mount Merapi National Park (MMNP). Nine years after the eruption, the vertical structure of vegetation can illustrate the progress of succession. This study aimed to analyze the tree composition and stratification in different forest damage levels after the 2010 Merapi eruption. The study was conducted in March 2019 at three stations, namely station A (heavy damage area), station B (moderate damage area), and station C (minor damage area). Vegetation parameters in each station were taken in a 10x100 plot and were processed using a tree profile diagram. Abiotic parameters were measured in each plot and analyzed using the correlation test. The results showed that the three stations were still dominated by the tree in Stratum C, but the tree density and tree height varied in proportion to the damage level. Station A in the heavy damage area has the lowest tree density (23 trees/0.1 ha) with a maximum tree height of 12 meters, in contrast to Station C in the minor damage area with tree density reaching 195 trees/0.1 ha and maximum tree height reaching 30 meters. Nine years after the Mount Merapi big eruption, the MMNP forests in Yogyakarta Province are still classified as young secondary forests.
