The high production of shallots (Allium cepa. L) causes a large amount of shallot waste in the form of shallot skins, which are organic wastes with a light weight, easily dispersed, disturbing the landscape and polluting the environment as well as being a source of disease. So that it is necessary to process waste into materials that have useful and even economic value, one of which is Liquid Organic Fertilizer (POC). The purpose of this study was to determine the levels of macro and micro nutrients in POC with varying concentrations of EM-4 bioactivator. In this study, the manufacture of POC with various concentrations of bioactivator 0, 25, 50, and 100 mL with a fermentation time of 14 days. Then carried out physicochemical observations, namely observing physical and chemical changes ranging from viscosity, color, odor and the presence or absence of gas in the POC made. The resulting POC was then tested for macro-nutrients (N, P, K and C-organic) and micro-nutrients (Fe, Mn, and Cu) using AAS and UV-Vis spectrophotometer. In this study, the best POC of onion peel waste was obtained at a concentration of 100 mL bioactivator with macronutrients N, P, K, C-Organic, each of which was 0.71; 1.45; 0.36 and 4.7%; while the content of micronutrients Fe, Mn, and Cu were 0.037, respectively; 0.0052, and 0.198%. It can be concluded that the levels of macro and micro nutrients have complied with SNI 19-7030-2004 except for C-organic elements which are still far below the standard, and POC made from onion skin has a high phosphorus content, so it is very suitable for use in plants that have high levels of phosphorus. require growth regulators (ZPT), especially for root growth.

Thomas langur (Presbytis thomasi) is an endemic primate to Aceh and North Sumatra. These primates have a local name, “Kedih.” Forest fires and forest functions conversion into oil palm plantations are pressure on their habitat and have decreased wild populations in nature. As arboreal animals, their movements depend heavily on the connectivity of vegetation. Comprehensive research is needed to obtain horizontal and vertical daily movement data of the thomas langur. This study used GPS to take coordinates, a camera to document Thomas langur and its food trees, and Thomas langur as a research object. The data recorded includes the coordinates of each forage tree, the type of forage tree, and the height of the canopy strata used by Thomas langur for foraging. The hardwood movement data was plotted on ArGis 10.1 to get the horizontal hardness movement area. Tree height data was obtained by measuring the tree height where Thomas langur stopped to look for food. Kedih movements to look for food are carried out daily from morning to evening. The results showed that the short length of movement was highly depend on the availability of forage trees. The denser the forage trees, the shorter the daily activities of Thomas langur. This daily movement can be done horizontally and vertically. Horizontally, Thomas langur moved to follow the forage trees, and vertically, Thomas langur moved by utilizing the height of the forage trees. Horizontally, Thomas langur moved 144.92 m in the rehabilitation block and 62.30 m in the protection block. The Thomas langur home ranged in the rehabilitation block is 27 ha, and 25 ha in the protected block. Vertically, Kedih in the rehabilitation blocks and protected blocks moved to trees with a height of 11-20 m, as much as 49%.

Human Development Index is one of the indicators that can be used to measure the success or performance of a country or region in human development. In 2022, Bali Province was one of the provinces with a "high" HDI achievement but is still faced with a gap in the HDI achievement rate between each region in Bali Province. The gap in the HDI achievement rate of each region in Bali Province indicates that the fiscal decentralization process in the regional autonomy policy has not been able to run optimally. This research examines the effect of fiscal decentralization on the human development index of regencies/municipalities in Bali Province using capital expenditure as a moderating variable to explain contingency factors that are thought to influence the effect of fiscal decentralization on the human development index. Using data on HDI achievement and realization of regional revenue and expenditure budgets of Bali Province for the period 2014-2019. The analysis technique used is Moderated Regression Analysis (MRA) with SPSS application. The results prove that partial fiscal decentralization has a significant positive effect on the human development index. Capital expenditure is able to weaken the positive effect of fiscal decentralization on the human development index. When a region has good regional financial independence, the local government will be able to manage its regional income in order to improve and improve public services, which will ultimately be able to improve the welfare of the community.

Singapore is the most significant contributor to tourist visits to Indonesia, but in 2015-2016, the number of tourist visits from Singapore decreased from around 1,59 million people to 1,51 million people. This study aims to determine the efforts of Indonesia's public diplomacy in increasing the number of tourist visits from Singapore through Wonderful Indonesia as nation branding. This research is focused on 2016 to 2019. This research used a descriptive qualitative method by using data collection techniques in the form of interviews, and document collection, such as official documents from private sources and internet sources in the form of articles in relevant journals and publications, and can be ascertained their validity. The author also uses three stages of data analysis according to Miles and Huberman (1994), including data reduction, data presentation, and drawing conclusions or data verification by data triangulation to explain the data obtained from the field in detail and clearly. The study found that Indonesia's public diplomacy efforts, which involved non-state actors by promoting Wonderful Indonesia, had a positive impact on tourism from Singapore. These efforts not only increased the number of tourist visits, but also boosted the country's foreign exchange income and earned recognition for the actors involved. Overall, the objective of these initiatives was to promote Indonesian culture, foster good relations with the Singaporean public, and create a favourable impression of Indonesia as a tourist destination. However, this promotional activity still has several obstacles due to the lack of infrastructure conditions in Indonesia around tourist destinations and Indonesia's level of security, as well as a small promotion budget.

Currently, there are many programs from the government related to urban villages. One of them is Kampung Kota Baru Tengah in Balikpapan City, which is the location for the Community-Based Settlement Environmental Management program (KOTAKU Program). The socialization program is carried out with an approach to the informal community. Socialization through community media is the mainstay of the government so that existing programs can be realized properly in society. This study aims to see the similarity of perceptions regarding space as a place to live. Considering that a common perception is one of the first steps to achieving the success of the KOTAKU program, where a common perception of where to live will become the vision of development in residential areas so that people will be more consistent in implementing the KOTAKU program. This study uses Multidimensional Scaling (MDS) analysis, which will then map the perceptions of settlements. The results of the perception mapping formed show that individuals in each community have different perceptions of settlements. Based on perceptions of reconciliation grouping, we found that 51% chose identity as the main reason for staying and 48.5% chose location dependence as the main reason for staying. This perception formed in the community suggests that government strategies for environmental and housing improvement programs are advocated to reflect or strengthen people's sense of identity and place dependability. Strengthening this sense of identity can be linked to any development activity that can reflect local wisdom, while the location dependency aspect can be linked to improving settlement infrastructure.

Madura is an area in East Java that has a negative stigma from the wider community. This is inseparable from the existence of Carok as a last resort to solve problems for the Madurese people. It is necessary to reconstruct through historiography to reduce the negative stigma. In some previous studies, it examined Carok which was reviewed from the law in Indonesia and the history of the Madurese people to the character of the Madurese people. However, the research has not explained the history of the conflict, especially Carok in Madura. Therefore, researchers use historical methods to explore Carok 's history in detail to know the development of Carok and its relevance to Settong Dara, the values of Carok, and Carok 's understanding of efforts with Settong Dara to reduce negative stigma in Madurese society. The research results obtained are that Carok was known during the Dutch colonial period. At that time, dutch people were moved to challenge the Dutch after the death of Sakera. However, the Dutch fought to make the image of celurit and Madura ugly. Before committing Carok, the two sides in the dispute must first meet the requirements. In the present time, this requirement has been ignored by some people, causing a shift in the meaning of Carok which causes a negative stigma. If examined further, various values in Carok will be known.

Published: June 2023

Ekonomik coğrafyada 1990’lı yıllara kadar değer zincirinin son aşaması olarak ele alınan tüketim konusu, günümüzde hem disiplin içinde hem de toplumsal-ekonomik yapıyı açıklamada önemli bir güce sahip olmuştur. Böylece tüketimin coğrafyaları çeşitli kimliklerin ve söylemlerin anlam ürettiği ve çatıştığı, mekânın ve toplumsal ilişkilerin yeniden üretilip tasarlandığı yeni bir ele alış ve yaşam biçimine dönüşmüştür. Bu bağlamda tüketim mekânlarının analiz edilmesini sağlayan en önemli kavramlardan biri “üçüncü yer”dir. Üçüncü yer, ev ve işyeri dışında kalan hem boş zamanın hem de tüketim eyleminin ve sosyalleşmenin mekânı olarak adlandırabileceğimiz insanların birbiriyle etkileşime girdiği kahve evleri, barlar, kafeler, kuaförler, kitabevleri vb. mikro mekânlara karşılık gelmektedir. Bu bağlamda bu çalışmanın amacı hem bir ticari tüketim mekânı hem de bir yerel ve küresel kafe zinciri olan Starbucks ve Simit Sarayı’nın üçüncü yer olma durumunu karşılaştırmalı olarak analiz etmektir. Nitel araştırma yöntemi kullanılan çalışmada 26 tüketici ve 8 yönetici ile derinlemesine görüşmeler ve saha gözlemleri yapılmış ve sözkonusu nitel veriler Maxqda programında analiz edilmiştir. Bulgular, Starbucks ve Simit Sarayı’nın üçüncü yer olma kriterlerini taşıdığını göstermekle birlikte, her iki tüketim mekânın Oldenburgcu anlamda bir geleneksel üçüncü yer değil, yeni nesil çağdaş bir ticari üçüncü yer olarak tanımlanması gerektiğini ortaya koymaktadır. Sonuç olarak bu çalışma, bir yandan üçüncü yer kavramsallaştırmasıyla coğrafyadaki meta-teorik yer kavramının nasıl işlemselleştirilebileceğine dair açılım sağlarken, öbür yandan tüketim mekânlarında tüketicilerin-yer ilişkisi temelinde bu ilişkinin anlamını, pratiğini ve boyutunu ortaya koyarak ekonomik coğrafya literatürüne katkı sağlamaktadır.

Objectives. The purpose of this work was to create a special entrance test for first-year students starting to learn a new foreign language. To achieve the research objective, the study analyzed data on testing language/linguistic proficiency and motivation for learning a foreign language. A range of test parameters identifying both abilities and motivation to learn a foreign language in general, but not related to learning a specific language, were highlighted. The identified parameters were used to inform a questionnaire tested on a group of students, whose level of abilities and motivation had already been ascertained. The findings about students were compared with the already known empirical data to support the improvement of test items.

Methods. To describe a special entrance test for first-year students starting to learn a new foreign language in a non-humanities higher education institution, a test technology for identifying certain cognitive, psychological, intellectual, motivational characteristics of a student's language personality was created. The developed test parameters served as the basis for constructing several heterogeneous test blocks.

Results. The initial version of the test obtained was verified by pilot testing first-semester-first-year students. Expert assessments of the foreign language potential learning on the part of students were used to evaluate the reliability and validity of the test. A subsequent correction of tasks and responses was carried out in light of the verification results.

Conclusions. A recommendation to conduct this kind of testing prior to the first semester with the aim of forecasting the success of foreign-language educational activities of students enrolled in the foreign language study group from the “starter” level is formulated. The results of such diagnostics can be used to draw up personified adaptive training programs within the educational process.

Objectives. An urgent task in the context of modern radio and television systems is to improve the quality and quantity of transmitted information. For example, the use of multiple amplitude-phase shift keyed (APSK) signals—16-APSK and 32-APSK—in digital satellite television systems of the Digital Video Broadcasting-Satellite2 (DVB-S2) standard made it possible to transmit 30% more data in the same frequency bands in comparison with the previous DVB-S standard. Such increases in information transmission rates impose more stringent requirements on hardware. An important role in the reception of APSK signals, as well as the signals of other coherent signal processing systems, is played by the stability of synchronization systems. The presence of operational errors can significantly reduce the quality of information reception. The aim of the present work was to analyze the effect of phase and clock synchronization errors on the reception noise immunity of APSK signals with a ring signal constellation structure.

Methods. The study used statistical radio engineering methods informed by optimal signal reception theory.

Results. The effect of phase and clock synchronization errors on the reception noise immunity of APSK signals having a signal constellation ring structure is analyzed. The dependencies of the bit error probability on the magnitude of the phase shift and the clock offset were characterized. The effect of synchronization errors on reception quality were compared with the known results for quadrature amplitude modulation (QAM) signals.

Conclusions. At an acceptable energy loss of no more than 1 dB, the critical phase error can be considered as 2°-3°, while the critical clock error is 3-4%. A coherent receiver of APSK signals is more sensitive to the phase error of reference oscillations than a similar receiver of QAM signals, whereas clock errors have the same effect on the reception quality of these signals.
Dispersion of optical constants of Si:PbGeO crystal in the terahertz range

Objectives. Advances in laser physics over the last decade have led to the creation of sources of single-period electromagnetic pulses having a duration of about 1 ps, corresponding to the terahertz (THz) frequency range and a field amplitude of several tens of MV/cm. This allows the electrode-free application of an electric field to a ferroelectric for observing not only the excitation of coherent phonons, but also ultrafast (at the sub-picosecond timescale) dynamic polarization switching. To detect polarization switching, a pump-probe technique is used in which a THz pulse is used with an optical probe. Since its intensity is proportional to the square of the polarization, the signal of the optical second harmonic is used to measure polarization switching under the action of a THz pulse. To evaluate switching efficiency, both linear (refractive index and absorption coefficient) and non-linear optical characteristics (quadratic and cubic susceptibilities) are required. For any application of ferroelectric crystals in the THz range, knowledge of the relevant linear optical characteristics is also necessary.

Methods. The technique of THz spectroscopy in the time domain was used; here, a picosecond THz pulse transmitted through the crystal is recorded by strobing the detector with a femtosecond optical pulse. The THz-induced dynamics of the order parameter in a ferroelectric was studied by detecting the intensity of a nonlinear optical signal at the frequency of the second optical harmonic.

Results. The transmission of a THz wave and the intensity of second harmonic generation on a lead germanate crystal doped with silicon in the time and spectral domains were measured. On this basis, the absorption coefficient dispersion and cubic nonlinear susceptibility were calculated in the range of 0.5-2.0 THz. The presence of a region of fundamental absorption near the phonon modes was confirmed along with a resonant enhancement of the cubic nonlinear susceptibility for two phonon modes Ω1 = 1.3 THz and Ω2 = 2.0 THz.

Conclusions. The proposed technique is effective for analyzing the dispersion of the optical characteristics of ferroelectric crystals. The significantly improved spectral resolution (0.1 THz) increases the accuracy of determining nonlinear susceptibility due to the detailed analysis of the linear and nonlinear contributions to the second harmonic intensity.
Method for synthesizing a logic element that implements several functions simultaneously
Authors: Sovetov S. I. , Tyurin S. F.
Published: June 2023

Objectives. The basic element of a field-programmable gate array is a lookup table (LUT). While in canonical normal form LUTs generally implement only one logical function for a given configuration, in this case, there is always an inactive pass transistor element. Moreover, using a single LUT for a single function reduces system-on-a-chip (SoC) scalability. Therefore, the purpose of the present work is to develop a LUT structure for implementing several logic functions simultaneously on inactive transmitting transistors.

Methods. The evolution of LUT structure is presented for three variables, in which the number of simultaneously implemented functions increases. To implement additional functions, the logical device was decomposed with a different number of variables. The structures were modeled in the Multisim electrical simulation system.

Results. The presented simulation of more than two logic functions on inactive parts of the LUT shows the simultaneous operation of two and four logic functions. The complexity for a different number of variables and number of implemented functions is compared.

Conclusions. The simulation results demonstrate the operability of LUT structures in which several logical functions are performed. Thus, when implementing additional functions in the new structure, a smaller number of transmitting transistors is required as compared to a conventional LUT, thus increasing device functionality. The presented solution can be used to increase the number of simultaneously implemented functions of the same variables, which can be important e.g., when implementing code transformations.

Objectives. The wear monitoring of metal structural elements of power plants—in particular, pipelines of nuclear power plants—is an essential means of ensuring safety during their operation. Monitoring the state of the pipeline by direct inspection requires a considerable amount of labor, as well as, in some cases, the suspension of power plant operation. In order to reduce costs during monitoring measures, it is proposed to use mathematical modeling. This work aimes to develop a mathematical model of a diagnostic system for assessing the probability of detection of defects by solving inverse problems.

Methods. A binomial model for assessing the reliability of monitoring, comprising the Berens-Hovey parametric model of the probability of detection of defects and a parametric model based on studying test samples, was analyzed. As an alternative to this binomial model, a computational method for assessing the reliability of non-destructive testing systems by solving an inverse problem was proposed. To determine the parameters of the defect detection probability curve, the model uses data obtained by various monitoring teams over a long period of power plant operation. To serve as initial data, the defect distribution density over one or more of the following characteristics can be used: depth, length, and/or cross-sectional area of the defect. Using the proposed mathematical model, a series of test calculations was performed based on nine combinations of initial data. The combinations differed in the confidence coefficient of the initial monitoring system, the parameters of the distribution of defects, and the sensitivity of the monitoring system.

Results. The calculation data were used to construct curves of the probability density of detected defects as a function of the defect size, recover the values of the defect distribution parameters under various test conditions, and estimate the error of recovering the parameters. The degree of imperfection of the system was estimated using the curve of the detection probability of a defect by a certain monitoring system.

Conclusions. Under constraints on the data sample size, the proposed methodology allows the metal monitoring results to be applied with greater confidence than currently used methods at the same time as evaluating the efficiency of monitoring carried out by individual test teams or laboratories. In future, this can be used to form the basis of a recommendation of the involvement of a particular team to perform diagnostic work.
