Abstract
This study delves into the potential of replacing soybean meal (SBM) with corn gluten meal (CGM) in the diet of Litopaeneaus vannamei. We aimed to investigate the effects of a dietary soybean meal replacement on various aspects of shrimp, including survival, biochemical indices, digestive enzymes, metabolomics, and disease resistance against Vibrio harveyi. To conduct the study, we fed 840 juvenile Pacific shrimp seven different diets, each containing varying levels of CGM. The control group received a diet with 0% CGM; the other diets contained 3%, 5%, 7%, 9%, 12%, and 14% CGM. Each group comprised three replicates, and the shrimp were fed their diets for eight weeks. Our findings revealed that the survival rate of the shrimp ranged from 90.83% to 97.50% and did not differ significantly between the control and those fed diet treatments 2–5. Additionally, there were no significant differences in crude protein, moisture, and lipid content. However, we observed that total antioxidant capacity content increased with the dietary inclusion of CGM. Furthermore, malondialdehyde content decreased with increasing CGM levels, while superoxide dismutase increased, indicating no obvious oxidative damage was observed in CGM treatment groups. Interestingly, shrimp fed diets 2 and 3 had considerably lower alanine aminotransferase activity than shrimp in the control group. The disease resistance in shrimp was improved across all treatment groups, with a notably higher CGM inclusion having the highest level of mortality during the challenge test. Finally, we analyzed the metabolomics data and found PCA score plots clearly separated the control group and shrimp fed CGM diets. Our study revealed that a 3% substitution rate of SBM with CGM can enhance survival and immunity, regulate metabolites and improve disease resistance.

Abstrak. Penelitian terhadap pewarna alami dari ubi jalar ungu, dan wortel telah dilakukan. Penelitian ini bertujuan untuk mengetahui karakteristik pewarna ubi jalar ungu dan wortel terhadap rentang serapan cahaya matahari. Serapan panjang gelombang pewarna ubi jalar ungu terjadi pada rentang 420–470 nm, energi gap yang diperoleh berdasarkan panjang gelombang maksimum (444 nm) adalah 2.79 eV. Sedangkan pada pewarna wortel dan campuran kedua pewarna (5:5), serapan panjang gelombang terjadi pada rentang yang sama yaitu 400 – 450 nm sehingga energi gap yang diperoleh berdasarkan panjang gelombang maksimum (426 nm dan 424 nm) adalah 2.91 eVdan 2.92 eV. Nilai energi gap yang didapat pada semua sampel relatif besar mengakibatkan tidak maksimalnya nilai arus dan tegangan yang didapat pada pengujian I-V sehingga penentuan efisiensi dan karakteristik DSSC yang diperoleh sulit ditentukan. Abstract. Research on natural dyes from purple sweet potatoes, and carrots has been done. This study aims to determine the characteristics of purple sweet potato and carrot dye on the range of sunlight absorption and functional groups for DSSC applications. Natural dyes from purple sweet potatoes and carrots were extracted using maceration and evaporation methods. Extraction results obtained were then tested for optical properties using a UV-Vis Spectrophotometer and Fourier Transform InfraRed (FTIR). The results showed that the absorption wavelength of purple sweet potato dye occurred in the range of 420–470 nm, the energy gap obtained based on the maximum wavelength (444 nm) was 2.79 eV.. While in carrot dye and a mixture of the two dyes (5:5), the wavelength absorption occurs in the same range, namely 400-450 nm so that the energy gap obtained based on the maximum wavelength (426 nm and 424 nm) is 2.91 eV and 2.92 eV. The energy gap values obtained in all samples are relatively large, resulting in not maximal current and voltage values obtained in the I-V test so that it is difficult to determine the efficiency and characteristics of the DSSC obtained.

Abstrak. Oksigen memainkan peranan vital dalam tubuh untuk mengatur sistem peredaran darah. Namun jika kadar saturasi oksigen dalam darah (SpO2) berkurang atau tidak mencukupi maka dapat menyebabkan sesak nafas, bahkan dapat mempengaruhi fungsi kerja otak. Perangkat oksimeter digunakan untuk mengukur kadar saturasi oksigen dalam darah dengan pengukuran secara non-invasif, sehingga kekurangan oksigen dalam darah dapat dideteksi lebih awal. Oksimeter yang tersedia saat ini umumnya menampilkan hasil SpO2 tidak terhubung ke jaringan sehingga tidak dapat dipantau secara jarak jauh. Oleh karena itu diperlukan suatu perangkat yang dilengkapi dengan fitur monitoring dalam jaringan agar dapat memantau kondisi partisipan secara real-time. Penelitian ini bertujuan untuk mengembangkan sistem monitoring pengukuran saturasi oksigen dalam darah yang dapat diakses secara remote menggunakan smartphone. Alat rancangan ini menggunakan sensor MAX30100 dan NodeMCU ESP8266 sebagai mikrokontroler. Hasil pengukuran alat rancangan dapat dipantau secara real-time melalui website menggunakan aplikasi Blynk. Data pembanding yang digunakan adalah alat Oksimeter komersial. Pengujian telah dilakukan pada partisipan laki-laki berusia 14 dan 22 tahun, dan perempuan berusia 18 dan 45 tahun. Hasil pengujian secara keseluruhan menunjukkan bahwa alat yang dirancang relative sama dengan oksimeter komersial, yang ditunjukkan oleh nilai thitung ttabel. Abstract. Oxygen plays a vital role in regulating our blood circulation system. However, if the oxygen levels in the blood decrease or are insufficient, it can cause shortness of breath and even affect brain function. To address this problem, an oximeter provides an effective solution by providing a device that can measure blood oxygen saturation without having to place any device inside the body. Currently available oximeter devices usually only display the SpO2 results on the device itself. Therefore, a device with a remote monitoring feature is needed to monitor participants’ condition in real-time. This research aims to develop a remote-access blood oxygen saturation measurement monitoring system using the MAX30100 sensor and the NodeMCU ESP8266 as the microcontroller, the values can be viewed in real-time on website by the Blynk app. The comparison data used is a comercial oximeter device. The participants were the males aged 14 and 22 years, and the female aged 18 and 45 years. Herein, we found that the designed instrument shows excellent performance in which ttest ttable from overall data.
Citing the Architecture of the Holocaust as a Method of Critique in Contemporary Artistic Practices: Zbigniew Libera, Zoran Dimovski, and the Use of Scale Models
Authors: Jankov Sonja 
Published: October 2023

This paper presents how visual contemporary art can form intertextual relations to the architecture of the Holocaust. For that purpose, two works are used as examples and analyzed in more detail: Lego. Concentration Camp by Zbigniew Libera (1996) and Diamond Dust by Zoran Dimovski (2021). This paper shows how these artists cite architecture of the Holocaust by scale-modelling and additional elements that give their works complex semantic layers. This paper also includes discussion about invisibility and visibility of concentration and extermination camps, as well as the segment that explains the difference between the use of architectural scale models by the Third Reich propaganda and by contemporary artists. This paper concludes how, when cited in works of contemporary art, architecture becomes a complex sign shifted from one discourse into another and from one historic period to the present, a phenomenon embraced by artists to criticize the socio-political context of its creation, but also to criticize the alarming phenomena of today’s era.

Authors: Sankarov Ali 
Published: October 2023

The article analyzes the identity of followers of Islam in the Republic of Bashkortostan from the point of view of the discursive tradition.The purpose of this study is to establish the features of the formation of Muslim identity in the territory of modern Bashkortostan. The subject of the study is the formation of Muslim identity in modern Bashkortostan. The object of the study are individual residents of the Republic of Belarus who profess Islam. To conduct the study, a set of field research methods was applied: direct observation of the object of study, survey, questionnaire. In the course of the study, the author makes a distinction between different groups of Muslims in Bashkiria. The author of the article examines in detail the various types of religious identity of Muslims of Bashkortostan. The relevance of this study lies in the fact that in the conditions of modernization of Russian society, its religiosity is increasing. At the same time, there is a certain blurring of the religious identity of Russian Muslims due to the globalization of culture. The author of the article suggests the incompleteness of the formation of religious identity due to a number of objective factors, in particular, due to the lack of clear differentiation between religious and ethnic identity, as well as differences in the ideals and values of different generations. The novelty of the research lies in the establishment of new factors influencing the formation of the Muslim identity of the inhabitants of modern Bashkortostan.

The present work is devoted to the topical topic of the role of technoparks in the modern globalization processes of the world and national economy. This is far from an accidental fact, since the specific structure of the modern world order poses special challenges to the societies of the post-Soviet space. The prospects for their development and equal participation in modernization processes depend on their ability to meet new requirements. In this regard, its driving mechanisms, affecting almost all states and societies, require deep rethinking and careful analysis. The paper pays special attention to the phenomenon of "silicon valleys", the role of science in the USA and the countries of Southeast Asia, and makes a comparative analysis of their specific features. Based on the data obtained, the degree of lag of post–Soviet societies will be determined, measures to overcome it are proposed, first of all, by reforming the educational system and science, which automatically put the human factor and intellectual capital in the first place. The work uses an interdisciplinary approach of socio-humanitarian disciplines, in particular, socio–cultural anthropology, semantics, structural, comparative analysis, on the basis of which the problems of post–Soviet societies are identified, modern modernization and globalization processes are analyzed. The work is aimed at a wide range of readers interested in the phenomenon of "silicon valleys", as well as scientists in the fields of politics, law, sociology, economics, cultural anthropology.

Published: October 2023

The consequences of these earthquake waves cause damage to buildings ranging from light damage to heavy damage. Dealing with the case, it is necessary to plan and implement earthquake-resistant building structures, especially in high-rise buildings. Another factor that needs to be considered is the function of the room which affects the column height when the column height is different and it causes uneven stiffness from the ground floor to the top.
The aim of this study was to find out the effect of variations in column height on the performance of multi-storey building structures in terms of shear forces, floor drift and buckling load (Pc). The method used in this study was the response spectrum method. The spectrum response is the maximum response of a Single Degree of Freedom (SDOF) structural system, both acceleration, velocity and displacement due to the structure being loaded by a certain external force. Before carrying out the analysis using the response spectrum method, a structural model was undertaken by varying the column height on the 1st floor into 3 variations.
Dealing with the results of the analysis on the building structure model with varying column height on the 1st floor, it indicated that the higher the column the maximum base shear force value increases. The higher the 1st floor column, the maximum floor deviation value increases. The higher the column the value of the column slenderness ratio increases and the Euler buckling load decreases.

Authors: Dejan kurlov  , Tej Marcovic  
Published: October 2023

Peat soil was categorized as soft soil, which means that the soil is in bad condition and problematic when construction was built on it. It was necessary to increase the carrying capacity of peat soils, one of which is chemical stabilization of the soil, by adding additives that can react with the soil and using new environmentally friendly methods.
In this study, samples of peat soil were taken from Buana Makmur Village km55, Dayun District, Siak Regency. The stabilizing agent used was sand as much as 5% by weight of dry soil, Bacillus Subtilis bacteria obtained from the Agriculture Laboratory of the Islamic University of Riau, and also CaCL₂ and Urea. The method for stabilizing the physical properties of peat soil in this study is the Bio-Grouting method, testing the physical properties of peat soil follows the procedures of ASTM (American Society For Testing And Materials) and SNI 1965-2008 for testing methods for determining water content for soil and rock in the laboratory. SNI 1964-2008 test method for soil specific gravity, SNI 8460-2017 geotechnical design requirements, SK SNI -04-05-1989-F fine sand used for construction, SNI-02-2801-1998 urea standard. To test the physical properties was carried out by providing variations in the mixing of bacterial cementation solutions with levels of 0% (without treatment), 5%, 10%, 15%, 20%, and 25% and then allowed to stand for 14 days using a tightly closed plastic container.
The results of testing the physical properties of peat soil found that the peat soil was included in the original soil type with water content = 407.45% and specific gravity (Gs) = 1.30gr, while from the physical properties tests carried out the highest water content occurred in the addition of bacterial cementation solution 10% = 177.2% and the lowest specific gravity occurs when the bacterial cementation solution is added 10% = 1.27gr.
Petrology and Mineralogy of Metamorphic Rocks in The Pringsewu District, Lampung Province, Indonesia
Authors: Sirait Happy Christin Natalia , Dewinta Veni 
Published: October 2023

The origin of metamorphic rock is greatly influenced by the temperature and pressure changes in every tectonic setting, especially in active subduction margins. One of the wide outcrops of metamorphic rock occurs in the Pringsewu District, Lampung, and it is a part of the Palaeozoic Gunung Kasih Complex. The presence of metamorphic rocks in Pringsewu has raised several questions and debates for some time due to the lack of research and field evidence found in this area, especially, since the origin of metamorphic rock in Lampung has been rarely studied. This research aims to determine the metamorphic rock facies and the tectonic setting underlying the formation of metamorphic rocks in the study area.
Petrographic analysis on 19 thin-section samples shows that metamorphic rock in the research area can be divided into two regions i.e., western and eastern regions. The Eastern part is characterized by muscovite-epidote schist and greenschist which consist of quartz, muscovite, actinolite, epidote, and garnet as index minerals. Whereas the western part is characterized by quartzite and biotite-epidote schist that consist of quartz, biotite, and muscovite. Based on the mineral index, metamorphic rock’s protoliths are pelitic rock, mafic rock, and quartz-feldspathic sandstone. The metamorphic rock zonation shows the created temperature is from 280-550oC.
The foliation structure such as schistose and porphyroblastic texture in the whole rocks sample indicated that metamorphic rocks are created in medium-grade metamorphism and are characterized by the greenschist facies to epidote-amphibolite facies. The abundance of quartz, k-feldspar, and labradorite minerals show that metamorphic rocks came from the microcontinent which was caused by a collision between the intra-oceanic Woyla plate and West Sumatra microcontinent in the Cretaceous. Indications of tectonic activity that create the lithology in Lampung Province need more geological study, especially to determine the absolute age of the metamorphic rock.

Abstrak - Arsitektur selalu diliputi oleh konteks tempatnya. Hal ini tentu terkait erat dengan kesan visual yangtercipta dalam skala besar, yaitu skala kota. Sebuah kota dapat memiliki suatu identitas karena arsitektur didalamnya yang berhubungan dengan alamnya. Elemen pembentuk ruang kota akan menyesuaikan dan mengantisipasi menggunakan rancangan yang merespon fakta geografisnya. Penyesuaian tersebut dapatmenimbulkan nilai kebaikan visual yang berbeda.Kota seringkali dipisahkan begitu saja dari alam, ditambah lagi dengan kerusakan alam akibat ulahmanusia yang acuh - tak acuh. Pemikiran ini disebut dengan binary pairs, dimana sebuah kota dan alamdianggap bertolak - belakang dan tidak dapat disatukan. Manusia mengangkat tangan terhadap eksploitasi danpencemaran lingkungan. Valsson menuliskan bahwa pemikiran ini keliru, dan dapat diperbaiki dengan metodetingkat komplemen.
