Comparative analysis of the biotechnological potential of Knautia drymeia Heuff. and K. macedonica Griseb
Authors: Chrząszcz Małgorzata , Dos Santos Szewczyk Katarzyna , Dąbrowska Agnieszka , Tchórzewska Dorota
Published: April 2023

The present study of Knautia drymeia and K. macedonica is in line with the current trend of searching for new plant species that can potentially be used as medicinal herb materials. A comparative analysis of the morphological and anatomical structure of both species was performed together with the distribution of polyphenolic compounds, which was correlated with the tissue structure of plant organs. Quantitative phytochemical analyses were performed to supplement the biophysical analyses. Both species had a similar morphological, anatomical, and histological structure. Polyphenolic compounds were accumulated in the parenchyma tissue in an organ-specific mode, mainly in the leaves. The phytochemical analyses revealed organ- and species-dependent variations in the polyphenol content. Thus, the highest polyphenol amount was observed in the leaves, with equal levels of total polyphenols and phenolic acids in the leaves of K. macedonica and K. drymeia, respectively. The present study integrates morphological/histological analyses with investigations of the biotechnological/pharmaceutical potential of the studied plants and constitutes an innovative and holistic approach to the current research problem.
The EU's Socio-economic Development Against the Backdrop of the War in Ukraine
Authors: Boichenko Kateryna , Umair Ashraf Rana , Nuno Mata Mário , Cristian Gherghina Ștefan
Published: April 2023

The war in Ukraine affects the European Union (EU) member states asymmetrically. The purpose of the study is to determine changes in the development of the EU countries in three key directions: ‘economy and environment’, ‘business and trade’, and ‘people and work’; to identify clusters of countries with similar transformations; and to model the impact of the studied indicators on the level of public debt amid the war in Ukraine. The research methodology includes the definition of a complex indicator of changes in the socio-economic development of EU countries, correlation and cluster analysis, and modelling the influence of the studied factors/indicators on the level of public debt. Research of changes in the context of the proposed complex indicators and their components under conditions of war showed that the changes in the areas under review varied for EU countries. Against the backdrop of the war in Ukraine, 17 EU countries faced a slowdown in their socio-economic growth, among which Poland was the most severely affected. Modelling made it possible to determine that, amid the war, the most important factors for the EU public debt are inflation, labour market conditions, and the possibilities of the balance of payments and the international investment position incorporated into GDP. The conducted research proves that the war in Ukraine increases the scale and relevance of general challenges that cannot be addressed at the national level. Strengthening the European defence against external aggression is the entire task of the EU.

The Dialects of Panslavic, Serbocroatian, and Croatian: Linguistic Taxonomies in Zagreb, 1836–1997
Authors: Maxwell Alexander
Published: April 2023

If linguistic nationalism presupposes a homogenous national language, then “dialect” taxonomies become interesting objects of study. This article examines three instances of linguistic nationalism published in Zagreb. The three texts, published in 1836, 1919, and 1995, come from (1) Ljudevit Gaj and Jan Kollár, (2) Dragutin Prohaska, and (3) Miro Kačić. The different texts propound three quite different taxonomies of “dialects” within the imagined national language. Changing strategies of dialect classification imply different understandings of the national language, reflecting in turn changing political circumstances. The Panslavism of 1836 gave way in 1919 to interwar Yugoslavism, or alternatively Serbo-Croatism, which in 1995 then gave way to Croatian particularist nationalism. The article ends with speculations about future linguistic taxonomies.
BLENDED LEARNING IN HIGHER EDUCATION: AN APPROACH, A MODEL, AND TWO THEORETICAL FRAMEWORKS
Authors: Becher Araujo Moraes Simone
Published: April 2023

In the last 2 years Higher Education Institutions around the world were forced to make the transition to online and now evaluate and recalculate mistakes, successes and opportunities to continue or adapt teaching to Blended Learning methodology, since going back to what was in the past no longer seems to be a viable path. This paper, through a literature review, is a first approach within the concept and the theoretical frameworks that make Blended Learning a possibility and a strong ally to promote meaningful Teaching and Learning in Higher Education. Subsequently, it is planned to carry out a systematic bibliographic analysis in order to go a step further and identify the main challenges and opportunities that Blended Learning brings to Teaching and Learning in Higher Education in the (post) pandemic context.
Local Government-First Nation Treaty Agreements in B.C.
Authors: Johal Gurleen
Published: April 2023

Although there have been efforts from both federal and local governments towards reconciliation in recent times, there are very few modern treaties in B.C. An important component of reconciliation is repairing relations between the government and First Nations and treaties are an important way of doing so. Treaties according to the BC Treaty Commission are legal agreements between First Nations, and the provincial and federal government that ensures Indigenous rights and promotes reconciliation. Specifically, modern treaties can enable Indigenous self-governance, self-determination, economic sufficiency and land ownership. In 1991, BC Task Force joined and made new recommendations to improve the BC treaty process, leading to new provincial legislation about treaty-making in BC. As a result, the local government and First Nations made stronger efforts to engage in treaty negotiations across the province. Although several First Nations have participated in the treaty-making process, BC has only successfully signed seven modern treaties. Of the seven, the Tsawwassen treaty is the only treaty in an urban area. This paper aims to explore why there are so few modern treaties between the local government and First Nations in an urban context. Ultimately, this paper will draw from the Tsawwassen, Musqueam, Squamish and Tsleil-Waututh Nations to discuss the barriers that explain the limited number of modern treaties in BC and why some First Nations groups are reluctant to engage in treaty agreements with the local government.
Aesthetics in Identity Politics: Cumulative Aesthetics, Emplotment, and Empathy
Authors: Higgins Kathleen
Published: April 2023

Contemporary identity politics, politics based on affiliation with a particular societal group in contradistinction from one or more others, typically becomes galvanized in response to a sense that those so affiliated have been marginalized or harmed. Art and aesthetic gestures utilized in contexts of identity politics serve a number of roles, among them drawing attention to the marginalization or harm to specific groups, consolidating those who share a particular political identity, and promoting empathy for members of such groups’ members. Another aesthetic strategy frequently utilized in efforts to promote social justice toward particular groups is the use of cumulative aesthetics, in which the amassing of instances is used to achieve an impact.
Because so often aimed at rectifying arrangements that are perceived as unjust, groups that advocate on behalf of those who share their political identity tend to be energized in reaction to circumstances. There is a danger of their becoming too simplistic in their own perceptions, dividing the world into friends and enemies. The “Me Too” movement in the United States is taken as an example of a well-intended campaign that can encourage oversimplified analyses that potentially damage its effectiveness in achieving its own ends. This is particularly ironic because simplistic binaries are often at work in what causes marginalization or harm to such groups in the first place.
Aesthetics can be utilized to inflame binary oppositions. It can also complicate perspectives in ways that lead to a lessening of reactive political responses and greater rapport across the boundaries separating one group from another. This can happen, for example, when art heightens perception but resists the danger of reinforcing preestablished binaries. Such art has the potential to assist efforts toward social justice by enabling greater sensitivity toward members of groups one does not consider one’s “own”. The Zhuangzi is taken as an example of a work that might do this, despite the apolitical concerns of its author.

Extracting Personal Preferences for Architectural Attributes: Examining the Reliability of Several Direct and Indirect Questioning Methods
Authors: Tayyebi Seyed Farhad , Demir Yüksel
Published: April 2023

The personal satisfaction with the formal attributes of buildings has an underlying essence and needs some exploratory attempts to secure a reliable set of individual attribute satisfactions. This paper aims to discover reliable methods for extracting the personal preferences for the formal attributes by examining the accuracy of several questioning methods. Focusing on building facades, the attributes are defined at first to cover a wide range of architectural forms. The study then introduces eight methods of extracting personal preferences: four attribute-based methods directly ask participants for their attribute preferences, and four building-based methods extract each attribute satisfaction from the analysis of appreciation of architectural forms. A survey then extracts individuals’ satisfaction with the attributes via each method; the outcomes of each questioning method are examined by applying them into preference prediction of another set of building images integrated into the survey. The analysis shows that the most accurate results are achieved when participants directly express their opinions about the attributes illustrated in a building’s image. Among the building-based methods, considering all the visible attributes in the analysis of the building preferences can reveal the second-most accurate data. Finally, although the combination of both methods enhanced the result’s accuracy, the former method is more efficacious while a lower number of attributes are considered and knowledgeable people are addressed; otherwise, the latter method is practically more valid for laypeople and scalable to a large number of people.

Urban Art Practices in the Vision of Projective Aesthetics
Authors: Lisovetc Irina , Orlov Boris
Published: April 2023

Modern urban art practices (public art, street art, flash mob, performance, etc.), are engaged in a radical aesthetic transformation of everyday life. The problem of projective aesthetics is taken as a variant of the praxis of modern aesthetics. Projective aesthetics suggests that one should mark out art projects which are created in the real aesthetic experience and which represent topical cultural issues in daily human life. Being the subject of projective aesthetics, the main examples of that kind are the projects of actual art in the urban environment. It is a group of artifacts at the border of art and everyday life that is called urban art practices.
This article is devoted to the study of the features and possibilities of projective aesthetics in relation to contemporary urban art. Interacting with the developing practical aesthetics – environmental and urbanistic – the projective aesthetics allows us to include in the philosophical discourse the urban culture where actual art practices work.
In the relations between urban art and projective aesthetics a special place is given to the idea and practice of potentiations (Epstein’s concept). According to this concept, the potential of the contemporary city is revealed by means of art for creating a polylogue for intertwining various aspects and forms of city life and for developing a rhizome of urban culture.
City art practices, being a phenomenon of everyday life, represent in a single image all aspects of everyday life – from political, ethnic, national, and regional to aesthetic and artistic meanings.

Becoming Animal of Philosophy: Pragmatism, Pragrammatology, Speculative Pragmatism
Authors: Reynolds Anthony
Published: April 2023

I argue that American pragmatism can be understood as an effort to recuperate a sense of the animality of thought and thus as an example of what Deleuze and Guattari call a “becoming animal” within the field of philosophy. At issue in this becoming animal of pragmatism is the influence of Charles Peirce’s theory of abduction on the history of pragmatism from its origins to its more recent reception within Jacques Derrida’s (pra)grammatology and Brian Massumi’s speculative pragmatism. Predicated on the evolutionary notion that animal instinct is the source of language, thought, and inquiry, Peirce’s theory of creative inference, or “abduction” as he called it, has allowed generations of pragmatists to begin “shaking philosophy’s dust off their feet and following the call of the wild” (James); to recognize in the origin of their thought something like “the movements of a wild creature toward its goal” (Dewey); to define intellectual inquiry as “doing what comes naturally” (Fish), and to pursue such inquiry “without method” (Rorty). Emerging under the ostensible heading of a new “humanism”, pragmatism exceeds what Derrida calls “the anthropological limit” from the very start, relieving humanism of its exclusive claim to logocentrism by reinscribing the question if not the origin of the logos within the animal kingdom. Yet unlike Derrida, whose rejection of biological continuism in the name of difference prevents him from committing fully to the logic of abduction, Massumi is able to rehabilitate Peirce’s theory of abduction as the foundation for his speculative pragmatism as a result of his commitment to a processual ontology that rejects binary oppositions in favor of “disjunctive syntheses” and “zones of indiscernibility.”

Biopolitical Theory of Virtuosity in the Oeuvre of Glenn Gould
Authors: Rodić Bojana
Published: April 2023

Over the course of the 20th century, the concept of virtuosity went through a transformation and adapted to its increasingly globalized and technological culture. In that sense, virtuosic performance and its reception were subject to the workings of social, political, economic, and historical factors. The emergence of a media-networked society conditioned a change in the perception of the artist, who now creates and transmits her works using media. Contemplating the concept of virtuosity in the age of post-Fordism, originally posited in the bio-political theory of the Italian philosopher Paolo Virno, this text analyses the concepts of the general intellect, labor power, as well as public political performance. Its focus is on the creative oeuvre of Glenn Gould, whose work combined different layers of pianist and performance heritage, and offered a new type of interpretation. Harnessing the power of his idea, he succeeded in using his radical musical philosophy to re-examine virtuosic performance and create a hybrid art as a blend of music and technology. In Gould’s poetics, virtuosity was a skill that managed to transpose itself into the domain of media by building upon preceding discursivizations.

Evaluation of Driving Comparative Life Cycle Cost Assessment of Conventional and Electric Motorcycles in Indonesia: Monte Carlo Analysis
Authors: Yuniaristanto  , Hafidza Lsa Aldira , Sutopo Wahyudi , Hisjam Muhammad
Published: April 2023

The adoption of electric vehicles (EVs) is one of the solutions to reduce emission problems. Vehicle cost analysis is one of the keys to seizing the Indonesian market. As a consumer, it is not only the purchase price that needs to be considered, but the life cycle costs throughout ownership also need to be considered in the purchase. This study discusses the life cycle cost (LCC) of EVs in Indonesia, especially electric motorcycles (EMs), which will be compared with conventional motorcycles (CMs). In particular, this study aims to encourage the government's target for ownership of 2.1 million EMs in Indonesia by 2025. The novelty of this research is to develop a more comprehensive LCC model by considering the costs in terms of tangible and intangible to compare the two types of motorcycles using Monte Carlo simulation. This simulation is used to coordinate the behavioral uncertainty of motorcycle users. As a result, the value of an EM is more economical than CM for various users. The average value percentage of EMs is lower than CMs by 45% (IDR 30,6 million). In addition, several scenarios are also analyzed to maximize consumer welfare in Indonesia.
Predicting Human Reliability based on Individual’s Resting Period: Effect of Physical Workload Rate
Authors: Wahyuning Caecilia Sri , Atiko, Saras
Published: April 2023

When a person is exposed to a prolonged workload, he/she enters a fatigue phase, the indication is the decline of cognitive performance that leading to human error. As an integral part of a system, human contributes to system reliability; therefore, it plays an important role in potential failure. Those, it is necessary to investigate how human reliability relates to physical workload rate, in order to predict maximum work duration to eliminate potential failure. A physical experiment involving 20 participants was conducted to generate medium workload, followed by Stroop test to observe selective attention and cognitive control as a form of cognitive performance. The physical workload was observed through energy expenditure and oxygen consumption during physical activity, and cognitive performance through response error time on the Stroop test. The usage of Weibull distribution was aimed to obtain reliabilities for each participant. There was a decline in reliability for all participants from one test to the other. Based on scale and form parameters, the prediction of resting time was based on mean time to human error (MTTHE), and from this experiment, varied MTTHE from each participant were obtained. The variation was created by differences in physical performance, cognitive capabilities, and other contributing factors such as environment and time of the implementation of the experiment. From this research, it was evident that human reliability can be utilized to predict potential failure in humans, which then implies a preventive action is necessitated to prevent failure from manifesting in the shape of taking a break/rest or reducing work rhythm. The application of human reliability in human resource management can be directed towards fatigue management and operator-related operational management.
Application of Genetic Algorithms to Solve MTSP Problems with Priority (Case Study at the Jakarta Street Lighting Service)
Authors: Tjandra Sugih Sudharma , Setiawan Fran , Salsabila Hanoum
Published: April 2023

Transportation is one thing that is very important and is the highest cost in the supply chain. One way to reduce these costs is to optimize vehicle routes. The Multiple Traveling Salesman Problem (MTSP) and Capacitated Vehicle Routing Problem (CVRP) are models that have been extensively researched to optimize vehicle routes. In its development based on actual events in the real world, some priorities must be visited first in optimizing vehicle routes. Several studies on MTSP and CVRP models have been conducted with exact solutions and algorithms. In a real case in the Jakarta City Street Lighting Section, the problem of determining the route in three shifts is a crucial problem that must be resolved to increase worker productivity to improve services. Services in MCB (Miniature Circuit Breaker) installation and maintenance activities for general street lights and priority is given to light points that require replacement. Because, in this case, the delivery capacity is not taken into account, the priority of the lights visited is random, and the number of street light points is enormous, in this study, we use the MTSP method with priority and solve by a genetic algorithm assisted by the nearest neighbor algorithm. From the resolution of this problem, it was found that the travel time reduction was 32 % for shift 1, 24 % for shift 2, and 23 % for shift 3. Of course, this time reduction will impact worker productivity so that MCB installation can be done faster for all lights and replace a dead lamp.
Total Tardiness Minimization in a Single-Machine with Periodical Resource Constraints
Authors: Prata Bruno , Abreu Levi Ribeiro de , Nagano Marcelo Seido
Published: April 2023

In this paper we introduce a variant of the single machine considering resource restriction per period. The objective function to be minimized is the total tardiness.  We proposed an integer linear programming modeling based on a bin packing formulation. In view of the NP-hardness of the introduced variant, heuristic algorithms are required to find high-quality solutions within an admissible computation times. In this sense, we present a new hybrid matheuristic called Relax-and-Fix with Variable Fixing Search (RFVFS).  This innovative solution approach combines the relax-and-fix algorithm and a strategy for the fixation of decision variables based on the concept of the variable neighborhood search metaheuristic. As statistical indicators to evaluate the solution procedures under comparison, we employ the Average Relative Deviation Index (ARDI) and the Success Rate (SR). We performed extensive computational experimentation with a testbed composed by 450 proposed test problems. Considering the results for the number of jobs, the RFVFS returned ARDI and SR values of 35.6% and 41.3%, respectively. Our proposal outperformed the best solution approach available for a closely-related problem with statistical significance.

Studi Kasus Pembuatan Lengkung Idf Dan Perkiraan Hujan Rencana Di Kota Bekasi Dan Cikarang Berdasarkan Data Non-Stasioner
Authors: Ginting Segel
Published: April 2023

Perubahan wilayah dari perdesaan menjadi perkotaan menyebabkan terjadinya perubahan iklim. Iklim yang berubah tersebut menyebabkan terjadinyan peningkatan hujan ekstrim. Perubahan catatan data hujan ektrim, menyebabkan analisis frekuensi data tersebut menjadi tidak valid karena kondisi data tidak stasioner. Oleh karena hal tersebut, maka dilakukan adaptasi pembuatan lengkung IDF dan hujan rencana menggunakan data non stasioner. Contoh kasus yang digunakan adalah di Kota Bekasi dan Cikarang, dimana kedua kota tersebut telah berubah menjadi wilayah perkotaan, sehingga karaketristik iklimnya mengalami perubahan. Metode pembuatan lengkung IDF dengan persamaan Bell dan penentuan hujan rencana dengan menggunakan distribusi generalized extreme value (GEV) berdasarkan empat skenario. Skenario pertama (GEV-0) menggunakan asumsi parameter lokasi (mean) dan skala (standar deviasi) tetap (stasioner), skenario kedua (GEV-1) menggunakan parameter lokasi tidak tetap (non-stasioner) sementara parameter skala tetap, skenario ketiga (GEV-2) menggunakan parameter lokasi dan parameter skala  tidak tetap, sedangkan skenario keempat (GEV-3) sama dengan skenario GEV-2 namun prediksi parameter lokasi dan skalanya berdasakan data hujan tahunan. Lengkung IDF dan hujan rencana berdasarkan parameter non stasioner memberikan hasil peningkatan intensitas hujan dan hujan rencana. Kondisi demikian membuat perencanaan infrastruktur seperti drainase perkotaan harus adaptif untuk mengantsipasi terjadinya genangan yang lebih sering dimasa mendatang.
Studi Pengaruh Curah Hujan Terhadap Stabilitas Lereng Menggunakan Program Perisi
Authors: Aisah Elpita , Gofar Nurly
Published: April 2023

Hujan merupakan salah satu penyebab keruntuhan lereng. Infiltrasi hujan ke dalam tanah dapat meningkatkan kadar air tanah, menurunkan tekanan air pori negatif, dan meningkatkan berat isi tanah atau bahkan menaikkan muka air tanah. Tujuan penelitian ini adalah untuk menganalisis kondisi lereng di sepanjang Jalan Lematang Kota Pagar Alam, meliputi geometri dan kondisi tanah serta menganalisis curah hujan yang dapat mempengaruhi stabilitas lereng. Pengamatan dan analisis stabilitas dilakukan pada enam titik sepanjang jalan tersebut. Pengamatan awal dan pengujian laboratorium menunjukkan bahwa tanah pembentuk lereng adalah lempung dan lanau dengan plastisitas rendah. Sudut kemiringan lereng berkisar antara 27o hingga 39o, dan panjang lereng antara 60 dan 350 m. Analisis stabilitas menggunakan Metode Bischop menunjukkan bahwa secara umum lereng tidak stabil (FOS < 1,5), meskipun secara visual lereng dalam kondisi baik. Oleh karena itu, dipasang rambu peringatan untuk memperingatkan pengguna jalan agar berhati-hati. Dalam studi ini. program PERISI digunakan untuk mengevaluasi apakah hujan dapat mempengaruhi stabilitas lereng di masa yang akan datang. Program ini mengasumsikan panjang lereng tidak terhingga dan dikembangkan berdasarkan konsep tanah tak jenuh. Program ini membutuhkan tiga input yaitu: geometri lereng, IDF yang dihitung berdasarkan curah hujan yang tercatat di stasiun curah hujan Pagar Alam selama 30 tahun (1985 – 2015), dan karakteristik tanah yang diwakili oleh SWCC dan fungsi konduktivitas hidrolik, serta kekuatan geser tanah tak jenuh. Dari analisis menggunakan PERISI dengan hisapan awal -30 kPa didapatkan bahwa lereng dalam kondisi aman. Kondisi ekstrim disimulasikan dengan menerapkan curah hujan dengan durasi 30 hari berdasarkan IDF. Hasil penelitian menunjukkan bahwa terjadi penurunan faktor keamanan yang signifikan pada kedalaman 0 – 5 m. Dengan demikian dapat disimpulkan bahwa berdasarkan IDF curah hujan dengan intensitas 24 mm/hari selama 30 hari tidak menyebabkan terjadinya longsor di Jalan Lematang Kota Pagaralam.

Published: April 2023

Jalan tol adalah jalan umum yang penggunanya diwajibkan membayar tol. Penyelenggaraan jalan tol harus memenuhi Standar Pelayanan Minimal (SPM) Jalan Tol yang terdiri dari ukuran jenis dan mutu pelayanan dasar yang harus dicapai. Tujuan penelitian ini adalah untuk memeriksa pemenuhan substansi pelayanan aksesibilitas berdasarkan indikator kecepatan transaksi rata-rata pada Gerbang Tol (GT) Pasteur 1 mengacu pada Peraturan Menteri Pekerjaan Umum No. 16/PRT/M/2014 tentang SPM Jalan Tol. GT Pasteur 1 yang dioperasikan mulai tahun 2018 merupakan gardu masuk yang terdiri dari tujuh Gardu Tol Otomatis (GTO) dengan pembagian dua GTO untuk kendaraan multi golongan dan lima GTO khusus untuk kendaraan golongan I selain bus. Untuk memperoleh data kecepatan transaksi rata-rata pada setiap GTO, maka dilakukan survei waktu transaksi pada hari Senin sampai dengan hari Minggu dengan waktu pagi dan sore hari. Data hasil survei waktu transaksi kendaraan pada masing-masing GTO ditulis dalam formulir survei, selanjutnya dilakukan pemilahan data untuk memisahkan data transaksi yang gagal agar tidak disertakan dalam pengolahan data. Pengolahan data dilakukan dengan cara memilah data hasil survei waktu transaksi yang memenuhi SPM Jalan Tol, yaitu maksimal 4 detik untuk setiap kendaraan. Kemudian mengukur populasi pencapaian SPM Jalan Tol, dimana pada gerbang tol yang memiliki GTO masuk ≥ 5 gardu disyaratkan 80 % waktu transaksi harus memenuhi SPM Jalan Tol. Berdasarkan hasil perhitungan jumlah kendaraan yang memiliki waktu transaksi ≤ 4 detik, diperoleh persentasenya berkisar antara 80% sampai dengan 100% dari populasi, maka dapat disimpulkan bahwa GT Pasteur 1 memenuhi SPM Jalan Tol ditinjau dari kecepatan transaksi rata-rata. Waktu transaksi rata-rata dihitung dengan cara membagi jumlah waktu transaksi dengan jumlah kendaraan, dapat dilihat waktu transaksi rata-rata pada GTO 1 dan GTO 2 lebih besar nilainya dibanding dengan GTO lainnya, hal ini disebabkan karena GTO 1 dan GTO 2 merupakan gardu tol multi golongan yang dapat melayani kendaraan besar. Waktu transaksi kendaraan besar lebih lama dibanding kendaraan kecil, karena dimensi kendaraan dan berat muatan yang menyebabkan jalannya menjadi lebih lambat ketika berada di GTO.
Effectiveness Of Portland Cement Type 1 In Stabilizing Soft Clay Soil As Subgrade For Road Construction
Authors: Iskandar Dedi , Putri Elsa Eka , Hakam Abdul , Fitri Arniza
Published: April 2023

Sawah Lunto – Talawi road segment (STA 139 + 700 m) in Sawah Lunto city, West Sumatera province has sustained major damages and been the scene of several accidents since the past few years. The degression of soft clay subgrade, which has a limited bearing capacity and makes it structurally impractical to sustain road construction, was discovered to be the source of these damages. As a recent option for enhancing soil qualities, soil stabilization by employing a variety of pozzolanic and industrial materials has gained popularity. The objective of this study is to investigate the effectiveness of Portland cement type 1 as stabilizing material in improving the soil properties and carrying capacity requirements for soft clay soil used as subgrade in road construction. To accomplish the objectives of this study, a laboratory testing procedure was implemented. Unconfined Compressive Strength (USC) values on natural soil and treated soil with Portland cement type 1 admixture were measured and compared during laboratory experiments. Soft clay soils were stabilized with varying percentages of Portland cement type 1 with the proportions of approximately 1%, 2%, 3%, 4%, 5%, 6%, 7%, and 10% by dry weight of soil during a 7-days curing period. Laboratory testing were performed in compliance with Indonesian National Standard (SNI): SNI 3420-2008 for testing Unconfined Compressive Strength. According to the results of laboratory testing, the UCS values increased roughly from 0.634 kg/cm2 (undisturbed natural soil) to 2.832 kg/cm2 (treated soil) by adding 3% of Portland cement type 1, and up to 8,024 kg/cm2 (treated soil) by adding 10% of Portland cement type 1. Based on the findings, it can be demonstrated that Portland cement type 1 can enhance clay soil's properties used as a subgrade for road construction, can create more stable road conditions, and can ultimately meet the technical feasibility requirements for the subgrade carrying capacity, particularly at the Sawah Lunto - Talawi road segment (STA 139 + 700 m).
Drosophila suzuki: Matsumura (Diptera: Drosophilidae): analysis of experimental conditions for its rearing and study in the laboratory

Published: April 2023

Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is an invasive pest species that uses a wide variety of commercial fruit as a breeding and feeding resource. The damage to the fruit generated by D. suzukii´ oviposition causes considerable economic losses. Therefore, the maintenance of D. suzukii in the lab conditions constitutes a fundamental tool for research proposal. Two of the determining factors affecting the lab rearing conditions are the culture medium and density. In this study, we evaluated the impact of these factors on three components associated with fitness: development time, larval-adult viability and body size, comparing the effects of three culture media: cornmeal (polenta), mashed potato and plum when the flies were reared at three densities: 10, 30 and 50 larvae per 5ml of culture medium. Our results revealed that the flies reared the cornmeal culture medium and at lower densities provide the better conditions for the maintenance of D. suzukii under lab conditions.

The second case of a bite by the “triangulate false widow” Steatoda triangulosa is reported on a human being. The case occurred in San Vicente, Buenos Aires, Argentina on a female 31 years old victim, who woke up felling a nuisance and spotting the spider on her arm. The spider inflicted two bites causing typical steatodism symptoms including local and radiating pain and malaise which lasted for about a day. In addition, the appearance of an erythema on each bite side that lasted about 10 days plus a haematoma in the first bite site which lasted for 3 days. The implications of the case in the context of current research in steatodism is discussed.

Dijital ekonomi, hızla büyüyen ve karmaşıklaşan bir yapıya sahip olup, işletmeler ve vergi idareleri için vergi planlaması ve vergileme alanında önemli zorluklar ve fırsatlar ortaya çıkarmaktadır. Küresel ölçekte faaliyet gösteren dijital şirketler, fiziksel varlıkların ve sınırların önemini azaltarak, gelirlerini ve karlarını düşük vergi oranlarına sahip ülkelere kaydırabilmekte ve böylece vergi yükümlülüklerini önemli ölçüde azaltabilmektedirler. Bu durum, vergi adaletini ve kamu gelirlerinin sürdürülebilirliğini zayıflatmaktadır. Geleneksel vergi sistemleri, dijital ekonomide ortaya çıkan yeni iş modelleri ve değer yaratma süreçleriyle baş etmekte zorlanmaktadır. Bu nedenle, dijital şirketlerin adil ve etkin bir şekilde vergilendirilmesi, hem ulusal hem de uluslararası düzeyde önemli fırsatlar sunmaktadır. Bu kapsamda, dijital hizmetler ve değer yaratma süreçleri üzerinden vergi alınmasına yönelik düzenlemelerin güncellenmesi, dijital şirketlerin tüzel kişilik ve mali faaliyetlerinin sınırlar ötesi niteliği dikkate alınarak yeni düzenlemelerin hayata geçirilmesi ve yeni dijital ürün ve teknolojilerin vergilemede aktif olarak kullanılması gerekmektedir. Bu çalışma, dijital ekonominin vergilendirilmesi bağlamında karşılaşılan zorlukları ve fırsatları ele alarak, büyük veri, yapay zeka, bulut bilişim ve Web 3.0 gibi teknolojilerin etkilerini değerlendirirken, işletmeler ve vergi idareleri için kapsamlı öneriler sunmayı amaçlamaktadır.

Penulisan ini dilatarbelakangi inkonsistensi norma hukum Pasal 2 ayat (2) Undang-Undang Nomor 31 Tahun 1999 jo Undang-Undang Nomor 20 Tahun 2001 tentang Tindak pemberantasan Pidana Korupsi. Dimana dalam norma hukum Pasal 2 ayat (2) khususnya unsur-unsur atau parameter kejahatan korupsi, persyaratan perbuatan pidana, dan ancaman sanksi pidana tidak memiliki kepastian hukum yang jelas, sehingga penormaan hukum yang inkonsistensi dan tidak memiliki kepastian hukum tersebut berpengaruh kepada penegakan hukum pidana korupsi khususnya pasal 2 ayat (2) UU Tipikor. Dari hal tersebut timbul permasalahan yang harus dianalisa yaitu : (1) Bagaimanakah seharusnya rumusan norma hukum pada ketentuan Pasal 2 ayat (2) Undang-Undang Nomor 31 Tahun 1999 jo Undang-Undang Nomor 20 Tahun 2001 tentang Pemberantasan Tindak Pidana Korupsi dimasa yang akan datang.Metode penulisan ini adalah yuridis normatif. Beberapa pendekatan penelitian yang penulis gunakan seperti pendekatan filsafat, konseptual, undang-undang, pendekatan kasus dan futuristik.Hasil penelitian adalah rumusan norma hukum Pasal 2 ayat (2) harus memiliki kepastian hukum baik kejelasan rumusan delik, dan penggunaan pasal tersebut tidak menimbulkan masalah penegakan hukum. Untuk kedepannya norma hukum tersebut harus diperbaiki melalui revisi undang-undang, atau membuat peraturan pelaksana berupa Peraturan Pemerintah atau Peraturan Presiden dan memperkuat Peraturan Mahkamah Agung yang sudah ada yang menjelaskan syarat pemidanaan Pasal 2 ayat (2).
