Authors: Adi Nur Isnawan
Published: March 2024

In general, Pesantren are educational institutions that focus on religious knowledge and general knowledge as the focus of learning. But it's different from the Pesantren in Gunung Kidul, Yogyakarta, which implements business education in it. This made the Pesantren the first Pesantren in Yogyakarta based on pre-employment. This is a challenge in itself because in order to market the products in it, various special strategies are needed in an era of intense business competition. In an era that is all internet like now, only with internet, computers and smartphones can be used as a tool to publish promotional activities for Wisata Edukasi Inspirasi Preneurship Al-Mumtaz (WEIPA) products. In making videos on how to make attractive advertisements with just a smartphone and then publishing them on social media, promotional activities can be carried out anywhere and anytime easily. Then create a website, which is about how to use and manage it optimally to support and improve product promotion capabilities. This service has a target of increasing the ability of WEIPA administrators and students in utilizing technology as an efficient medium in driving economic factors and not forgetting religious knowledge as their priority.

A healthy environment is an environment that has clean air, water and soil conditions and is free from pollution, and the area owned supports the creation of a healthy community. Automatically the environment will be protected from things that cause health problems, such as liquid, solid and gas waste. Also, avoid animals carrying disease germs, harmful chemicals, excessive noise pollution and other negative things. Conceptually, what can overcome environmental crises is to make eforts to preserve the environment by reforestation. The word preservation comes from "sustainable", which means to remain as it was before, not change, and last forever. At the same time, preservation means the process, method, act of preserving, protection from destruction and damage, preservation, conservation, and management of natural resources, which guarantees their wise use and the continuity of their supply while maintaining and increasing the quality, value and diversity. Environmental preservation is an effort to deal with problems that arise in an area. Therefore the 108 Thematic KKN Group 11 held environmental preservation, which applied the concept of greening by utilizing existing land around Halal Tourism belonging to the Islamic Boarding School, which is located on Jalan Wonosari KM 25 Dusun Joban, Beji Village, Patuk District, Special Region of Yogyakarta. This activity is a form of the community service program. The greening concept is carried out by planting several types of tree seeds by utilizing the land around the area. This greening activity is expected to raise a sense of community concern to always care for and care for the surrounding environment, in addition to providing skills and knowledge about making kokedama from coconut coir waste as a growing medium for ornamental plants.

The large amount of using smartphones makes businessmen and scientists create an application where it could be used as one of the ways for cashless payments. One of the tools for cashless payments uses a smartphone application called “Mobile Payment” or M-Payment. The development of M-Payment does not lose the concerns of a muslim towards the idea of syariah. The purpose of this research is to explore the factors that influences the users of M-Payment which are the millennial generation muslims in yogyakarta. This research uses 214 sample that are submitted through an online survey. The data will be processed using the Partial Least Square Structural Equation Modeling (PLS-SEM) approach with a SmartPLS 3.0. The results from the data analysis reveals the convenient variable, comparative variable, and risk perception significantly affects the users intention to acquire M-Payment. On the other hand, the beneficial variable, religiosity shows an insignificance affect of the users intention to acquire M-Payment. However, it shows that the effect of modern knowledge about riba does not moderate in this research. Therefore, M-Payment is able to give advantages, convenience, and safety towards the millennial generation of muslims. Besides that, the concerns of muslims towards the idea of syariah does not affect their intention to use M-Payment

Sea level anomaly (SLA) data spanning from 1993 – 2022 were used to analyze the characteristic of eddy current in Northwest Indonesian. An improved winding angle method was used and was able to detect 1663 anticyclonic eddies (AEs) and 1748 cyclonic eddies (CEs). The average eddy lifespan is approximately four weeks. The eddy in the West Indonesian Ocean has a radius ranging from 40 – 100 km and a high number of mesoscale eddy (radius more than 100 km) detected in the northern area of West Indonesian Ocean (4° N - 10° N). The eddy kinetic energy (EKE) increased proportionally with their radius, whereas the eddy vorticity decreased proportionally with their increasing radius. The seasonal cycles of eddy circulation in the west Indonesian Ocean were differ for both AEs and CEs, where AEs were dominated during east monsoon season (JJA) and CEs came with longer periods from November to March, yet for both AEs and CEs they have similar radius per month. During weak periods of both eddies, their meridional distributions differ; CEs tend to be formed in relatively lower latitude, while AEs were concentrated in relatively higher latitude. Data anomali permukaan laut/sea level anomaly (SLA) dalam kurun waktu 1993 – 2022 digunakan untuk mempelajari karakteristik sirkulasi arus eddy di perairan barat laut Indonesia. Metode Winding Angles yang telah dimodifikasi mampu mendeteksi 1663 anticyclonic eddies (AE) dan 1748  cyclonic eddies (CE). Rata-rata umur eddy yang terdeteksi adalah sekitar empat minggu. Mayoritas sirkulasi arus eddy memiliki radius 40 – 100 km dan eddy dengan radius berskala meso (lebih dari 100 km) banyak terkonsentrasi di bagian utara (4° N - 10° N) perairan barat laut Indonesia. Nilai energi kinetik eddy (EKE) bertambah sebanding dengan pertambahan radius, sedangkan nilai vortisitas berbanding terbalik dengan radius. Sirkulasi arus eddy di perairan barat laut Indonesia pada musim timur (JJA) didominasi oleh AE , sedangkan CE mendominasi di musim barat (DJF) dengan periode yang lebih panjang dari November hingga Maret, namun dengan rata-rata radius yang sama setiap bulannya. Pada saat periode di mana kejadian eddy minimum, ditemukan perbedaan letak distribusi meridional eddy bervortisitas tinggi yang menunjukkan CE lebih didukung pembentukannya pada lintang yang lebih rendah daripada AE.
Effect of Liquid Fertilizer on Seedling Enhalus acoroides Seeds (Linnaeus f.) Royle 1839 (Fam: Hydrocharitaceae)

Published: March 2024

The decrease in seagrass coverage and ecosystem harm to seagrass meadows is an annual occurrence resulting from both natural and human activities.  Seagrass seeding has been deemed an effective restoration method, but its application is restricted by suboptimal environmental conditions and constraints associated with directly planting seagrass seeds in their natural habitat. The influence of environmental parameters, particularly nutrients, significantly affect on seagrass seed survival. NPK liquid fertilizer is commonly used in aquatic plants and is readily accessible in the market. It serves as a crucial source of macronutrients for seagrass. This study investigates the impact of different concentrations of NPK liquid fertilizer on the survival rate, growth, and chlorophyll, a content of E. acoroides seedlings. The study took place between March and May 2023 at the marine biology laboratory of the marine science study program at Diponegoro University's Faculty of Fisheries and Marine Science. According to the Manova statistical test, the NPK liquid fertilizer had an impact on the growth rate, biomass, and chlorophyll-a. The seagrass seeding container of E. acoroides treated with a liquid fertilizer concentration of 4.5 ml/100l exhibited the highest average growth rate of 0.29 cm/day and a chlorophyll-a value of 12.395 mg/g, with a survival rate of 100%. Causal connections between statements ensure logical construction. In contrast, seedlings without liquid fertilizer treatment showed the lowest growth rate of 0.19 cm/day and chlorophyll-a values of 5.169 mg/g, with a survival rate of 85.19%. Technical term abbreviations such as 'cm/day' and 'mg/g' are explained when first used to ensure clarity. Based on these findings, using liquid fertilizer with a concentration of 4.5 ml/l exhibits potential for restoring seagrass ecosystems.
Simulation approach to study kinetic heterogeneity of gadolinium catalytic system in the 1,4-cis-polyisoprene production
Authors: Miftakhov Eldar , Mustafina Sofia , Akimov Andrey , Mustafina Svetlana
Published: March 2024

This article presents a novel simulation approach for solving the inverse problem of kinetic heterogeneity in polymerization processes, specifically focusing on the production of polyisoprene using a gadolinium chloride solvate-based catalytic system. The proposed method is based on the assumption that the distribution of active centers (ACs) can be described by model distributions. By utilizing primary physicochemical data, such as the polymerization rate and molecular weight distribution, the simulation approach automatically identifies the kinetic parameters, determining the Frenkel statistical parameter and solving the problem of kinetic heterogeneity. The experimental results revealed the presence of at least three distinct types of ACs, each contributing different proportions to the polymerization process. The simulation approach offers valuable insights into the complexities of catalytic systems and their role in polymerization, paving the way for optimizing reaction conditions and advancing industrial polymer synthesis processes. This study marks a significant step forward in understanding and controlling polymerization reactions, with potential implications for the development of innovative materials and industrial applications.

The molecular and cellular choreography of early mammalian lung development
Authors: Yang Xianfa , Chen Yingying , Yang Yun , Li Shiting , Mi Panpan , Jing Naihe
Published: March 2024

Mammalian lung development starts from a specific cluster of endodermal cells situated within the ventral foregut region. With the orchestrating of delicate choreography of transcription factors, signaling pathways, and cell–cell communications, the endodermal diverticulum extends into the surrounding mesenchyme, and builds the cellular and structural basis of the complex respiratory system. This review provides a comprehensive overview of the current molecular insights of mammalian lung development, with a particular focus on the early stage of lung cell fate differentiation and spatial patterning. Furthermore, we explore the implications of several congenital respiratory diseases and the relevance to early organogenesis. Finally, we summarize the unprecedented knowledge concerning lung cell compositions, regulatory networks as well as the promising prospect for gaining an unbiased understanding of lung development and lung malformations through state-of-the-art single-cell omics.

Laboratory outreach programs for K-12 students in the United States from 2020 to 2022 were suspended or delayed due to COVID-19 restrictions. While Southern Nevada also observed similar closures for onsite programs, we and others hypothesized that in-person laboratory activities could be prioritized after increasing vaccine doses were available to the public and masking was encouraged. Here, we describe how the Laboratory of Neurogenetics and Precision Medicine at the University of Nevada Las Vegas (UNLV) collaborated with administrators from a local school district to conduct training activities for high school students during the COVID-19 pandemic. The Science Education for the Youth (SEFTY) program's curriculum was constructed to incorporate experiential learning, fostering collaboration and peer-to-peer knowledge exchange. Leveraging neuroscience tools from our UNLV laboratory, we engaged with 117 high school applicants from 2021 to 2022. Our recruitment efforts yielded a diverse cohort, with >41% Pacific Islander and Asian students, >9% African American students, and >12% multiracial students. We assessed the impact of the SEFTY program through pre- and postassessment student evaluations, revealing a significant improvement of 20.3% in science proficiency (p < 0.001) after participating in the program. Collectively, our laboratory curriculum offers valuable insights into the capacity of an outreach program to actively foster diversity and cultivate opportunities for academic excellence, even in the challenging context of a global pandemic.
Calculating Nature’s Bill: Environmental Quality and the Critique of Economic Growth in the 1970s
Authors: Rhee Pollyanna
Published: March 2024

The article uses the ascendance of “quality of life” in the 1970s to underscore the connected development of the critique of economic growth and the rise of interest in environmental issues. In his 1970 State of the Union address, US president Richard Nixon proclaimed that the nation’s economic growth between 1970 and 1980 was projected to be greater than the growth of its entire economy from 1790 until 1950. But that growth did not mean Americans would be “richer in any real sense.” Instead Nixon declared that the time had come for “a new quality of life.” Concerns about the dominance of economic growth were not exclusive to the United States. In 1974 the English socialist member of Parliament Tony Benn expressed his belief that quality of life contained a bold social vision signifying “nothing less than the creation and the sustenance of system of society that enriches those who live in it.” Assessing quality of life appeared to offer a way to more accurately reflect the conditions and progress of the nation and respond to growing attention to pollution, energy use, and other environmental hazards. This article investigates attempts to measure quality of life and demonstrates the centrality of environmental quality in those efforts, as well as defenses of economic growth that followed. Although quality of life was conceived as a transformative alternative to economic indicators and a means to adequately address environmental issues, it also worked toward a contradictory objective of concealing the ambiguities of economic growth in order to maintain existing conditions.

Effects of Bacillus amyloliquefaciens on volatile components and nutrient element contents of Mentha piperita L. grown under salt stress
Authors: Tuğba Üner Songül , Cesur Turgut Aslıhan
Published: March 2024

Bacillus amyloliquefaciens (Ba) was applied to Mentha piperita L. (peppermint) seedlings grown at various salt levels (0, 50, 75, and 100 mM) for 42 days (six weeks). The study was conducted in a total of eight groups, with 24 seedlings per group. At the end of the study, the seedlings were analyzed for plant nutrient elements and volatile compound contents. The negative effect of salt was observed in almost all parameters. When all groups were evaluated for plant nutrient elements, Ba had a positive effect on Zn, Mn, Cu, and Na values compared to the control, but it did not show any effect on B, Fe, K, P, Mg, and Ca. In volatile compounds, limonene was detected as the major component in all groups. As a result of the evaluation based on limonene, the highest rate was found in the control, and the lowest rate was found in 100 mM NaCl. The salt-dependent inhibition between the groups with the highest and lowest limonene was 73%. While the negative effects of salt were observed in almost all parameters, the promoter effects of Ba were not as pronounced.
