Indonesia tampaknya perlu lebih giat lagi menggaungkan aspek-aspek yang dapat membuat negara ini menjadi maju. Salah satu aspek yang perlu digaungkan sejak dini adalah kesadaran akan pentingnya dalam membuat sebuah usaha, baik usaha mandiri maupun kelompok. Jika warga negara Indonesia mampu membuat sebuah usaha, maka kita mampu menyerap banyak SDM yang ada dan akan ikut membantu membangun negara kita ini menuju ke arah Indonesia maju. Pengembangan usaha harus didasari dengan dasar yang kuat, salah satu langkah yang bisa dilakukan yaitu dalam pembuatan proposal usaha. Proposal usaha yang dimaksud adalah kemampuan individu dalam membuat sebuah proposal dan berkaitan dengan usaha yang ingin dibuat. Kemampuan dalam membuat proposal usaha dapat diajarkan sejak SMA/SMK, para siswa diharapkan mampu memiliki pengetahuan mengenai proposal usaha dan diharapkan mampu untuk merealisasikannya. Tujuan utama peneliti dalam membuat PTK ini karena melihat kurangnya minat siswa dalam membuat proposal usaha karena para siswa merasa tidak memahami apa saja yang perlu dibuat dan tidak tahu apa usaha yang akan mereka coba. Oleh karena itu peneliti ingin melakukan PTK untuk meningkatkan kemampuan siswa dalam membuat proposal usaha dengan menggunakan penerapan model pembelajaran berbasis proyek. Model pembelajaran berbasis proyek ini memiliki kelebihan-kelebihan yang diharapkan mampu membantu siswa dalam pengerjaan proposal usaha, yaitu siswa diberikan permasalahan atau tantangan dengan tujuan agar siswa mampu mengetahui hal apa yang saat ini sedang banyak disorot atau sangat besar kebutuhannya, dengan mengetahui hal tersebut maka siswa akan memiliki ide-ide untuk mengajukan proposal usaha sesuai dengan kebutuhan disekitarnya saat ini. Hasil yang diperoleh yaitu terdapat pengaruh pemberian pembelajaran berbasis proyek yang dilakukan dalam upaya peningkatan pada tahap awal jumlah skor masih 54,86 selanjutnya pada siklus I sebesar 65,55 dan siklus II sebesar 81,67. Data ini merupakan bukti bahwa model pembelajaran berbasis proyek berpengaruh terhadap meningkatnya kemampuan dalam membuat proposal usaha. Peran guru selama pendampingan proyek disinyalir menjadi faktor utama keberhasilan tersebut, karena siswa menjadi lebih mudah berinteraksi dengan guru dan menanyakan hal-hal yang tidak diketahui oleh siswa.Kata Kunci : Model Pembelajaran Berbasis Proyek, Prestasi Belajar, Proposal Usaha

Carbon dots (CDs) have gained popularity in research due to their desirable characteristics in electrical, catalytic, and optical applications. The exploration of unique carbon sources with complex chemical compositions can open avenues for the straightforward production of multi-doped nanomaterials. In particular, prickly pear has distinctive properties and a mineral-rich composition, and high production yields under low water usage conditions. In this work, prickly pears were used to prepare fluorescent green multi-doped CDs through a carbonization technique in the presence of nitrogen, phosphorus, and nitrogen-phosphorus solutions at 180°C for 7 hours. Results from different characterization techniques such as Fourier Transform Infrared (FTIR), X-ray diffraction (XRD), UV-vis, and Potential demonstrated the functionalization of the surface, semi-crystalline structures, a broad absorbance at the UV range with a strong peak at 275 nm, stability in water, and negative surface charge of nitrogen-doped carbon dots (NCDs), phosphorus-doped carbon dots (PCDs), and nitrogen-phosphorus doped carbon dots (NPCDs). Overall, the prickly pear was demonstrated to be a suitable source for synthesizing multi-doped CDs while maintaining nano-synthesis towards sustainable and eco-friendly directions.

This investigation seeks to discern the aerodynamic differentials between rockets featuring straight fins and those with curved fins, focusing on the drag coefficient (cd), lift coefficient (cl), and moment coefficient (cm). Employing the computational fluid dynamics (CFD) methodology within ANSYS Fluent software, the research endeavors to provide comprehensive insights. The rockets under scrutiny share a common cylindrical body configuration, boasting a 70 mm diameter, a conical nose, and four symmetrically positioned fins along the lower body. The CFD analyses encompass subsonic Mach 0.6 and supersonic Mach 1.2 scenarios, with the angle of attack systematically varying from 0° to 25° at 5° intervals for each velocity setting. The outcomes of the simulations reveal notable trends: both cd and cl exhibit an upward trajectory, while cm experiences a decrement with escalating angles of attack and velocities. The culmination of Ansys CFD simulations for both rocket configurations unequivocally indicates superior flight performance for the straight fin rocket. This discernment is grounded in the observed amplification of drag and lift coefficients, coupled with the concomitant reduction in the moment coefficient, thus elucidating the nuanced aerodynamic distinctions between straight fin and curved fin rockets across varying flight conditions.

The increasing generation of glycerol as a waste from biodiesel production calls for its various consumptions, especially in producing industrial chemicals. However, the focus of popular studies in this process is on using noble metals as the catalyst. It should be shifted to a low cost and abundant element to ensure sustainability. Therefore, this study uses activated carbon from coconut shells to support a bimetal catalyst copper-nickel in converting glycerol into value-added products. The catalyst was synthesized via the wet impregnation method and was characterized using scanning electron microscopy-energy dispersive X-ray spectroscopy, Fourier-Transform infra-red spectroscopy, and a surface area analyser. It was revealed that the BET surface area (582 m2/g) is smaller than the pristine carbon because of the exposure to high temperature during calcination. The average pore size (1.7 nm) is also smaller than the coconut shell carbon due to the same effect. The surface functional groups mainly consist of carboxylic acids that is known to contribute to the hydrogenolysis of glycerol. At 20 wt% initial glycerol concentration, 20 bar and 200 °C, acetic acid, propylene oxide, carbon monoxide and acetaldehyde were detected as the products. A possible mechanism was proposed considering the aqueous-phase reforming of glycerol and the dehydration process. The optimum operating conditions in this case are 20 wt% initial glycerol concentration, 25 bar and 200 °C. More studies are needed to evaluate the reactions involved in aqueous-phase reforming of glycerol using the Cu-Ni doped on coconut shell activated carbon. In conclusion, glycerol can be converted to valuable chemicals under mild conditions by using the cost-effective catalyst.
Fabrication and Analysis of Physico-Mechanical Characteristics of Chemically Treated Bhendi Fiber Reinforced Thermoplastic Composites: Effect of UV Radiation
Authors: Haydar Zaman
Published: March 2024

Unidirectional polypropylene (PP) composites reinforced with bhendi fibers (BFs) were produced after BFs were subjected to UV light at different intensities. Mechanical parameters such as tensile strength, tensile modulus, and impact strength of irradiated BF/PP composites significantly improved compared to non-irradiated counterparts. To enhance their properties, different amounts of 2-hydroxyethyl methacrylate (HEMA) in methanol were applied to the surfaces of irradiated BFs, and UV light was subsequently used to cure them. Tensile strength, tensile modulus, and impact strength values rose by 32%, 20%, and 37%, respectively, after the optimized grafting and mechanical properties. Alkali solutions were applied to BFs for 30 minutes at varying temperatures and concentrations to alter their surfaces. Then, using the same UV light, BFs were photocured after being grafted with an optimal HEMA solution. Of all the composite samples treated with 10% HEMA, the alkali + 10% HEMA-treated composites exhibited superior mechanical performance. SEM studies exhibited that the optimized alkali with 10% HEMA treated composite had better dispersion than the 10% HEMA treated composite. Water absorption was significantly lower in the treated than in the untreated sample. According to weather studies, the treated specimens may have less loss tensile characteristics than the untreated specimens.

Authors: Pranto Karua  , Md Arifuzzaman  , Md Shariful Islam
Published: March 2024

Fiber reinforcement is one of the ways for the improvement of the mechanical properties of composite materials. Previously, it was seen that the fiber content in composites played a vital role in the mechanical properties of fiber-reinforced composites. Considering the benefits of natural fiber, in this work, jute fiber reinforced perlite/gypsum composites were manufactured with five different fiber contents ranging from 2.41 % to 4.82 %. The ratios of gypsum to perlite and gypsum to water were kept constant, and only fiber content was varied. The compression and flexural tests were conducted to investigate the effect of jute fiber content on the mechanical properties of jute fiber-reinforced perlite/gypsum composites. Results showed that both the compressive and flexural properties were improved up to certain jute fiber content. The compressive strength, modulus, and energy absorption of the jute fiber-reinforced composite were found to be the maximum at 3.01 % fiber content. The compressive strength of the composite with 3.01 % jute fiber content was 35.23 % higher than the composite with 2.41 % fiber content. The flexural strength, modulus, and energy absorption were maximum at 3.61 % jute fiber content. This study demonstrated that the addition of jute fiber to perlite/gypsum composites results in improved mechanical properties up to a certain percentage of jute fiber, beyond which the properties deteriorate.

Published: March 2024

Single-lap joints are by far the most widely used adhesive joints and have been the subject of considerable research over the years. It is used in the automobile and aerospace industry where bolted or riveted joints are impossible. The joint strength in adhesively bonded joints depends on the adhesive and adherend properties and adherend geometry. In this paper, both the adhesive property and adherend geometry are considered. Two types of adhesives, i.e., SBT9244 (flexible) and DP460 (stiff), and three types of adherend geometry, Single Lap Joint (SLJ), One Step Lap Joint (OSLJ), and Three Step Lap Joint (TSLJ) are considered, and the effect of these are investigated by using a commercially available software Abaqus. The maximum peel stress occurs in a lap joint towards the edges of the joint and is minimum around the center region. The maximum peel stress is responsible for the failure of the joints, and the objective of this research was to reduce the peel stress, i.e., provide a more uniform stress distribution. Soft adhesive maximum peel stress and shear stress occur in [Type-I] 8.6 MPa and 6.4 MPa, respectively. Similarly, stiff adhesive maximum peel stress and shear stress occur in [Type-I] 37.14 MPa and 20.44 MPa, respectively. It is found from this investigation that if a relatively soft adhesive (SBT9244) is used in the joint, then the stress distribution reduces compared to a stiff adhesive (DP460). On the other hand, if steps are introduced in the bonded region, the stress distribution becomes more uniform and increases the bond strength.

The purpose of this research is to see how the role and responsibility of movie theaters in implementing Law No. 33 of 2009, especially article 7 and maintaining security, understanding related to the law. Because with the right understanding, it will affect the application of theaters to ensure that they operate in accordance with existing regulations. The research method uses Hermeneutic analysis, in hermeneutics there are three components, namely understanding, interpretation and application, which is related to the cinemas that have understood, interpreted and applied the age classification of the audience by the Film Show Company (cinema). The results showed that in its application, the movie theater has tried to apply the law in accordance with applicable regulations, but there are still many obstacles, especially from people who are less concerned about the shows they watch in terms of age classification. Theaters have tried to apply the law, but theaters are unable to control the application of the law to be applied. According to film observers, the law has been implemented by theaters, but the age category information displayed on plasma TVs is so small that not all viewers pay attention to the information. The Film Censorship Board does not specifically have the right to revise this law, from LSF's perspective, this is sufficient because everything has been regulated in detail. The public is encouraged to be more aware of Law No. 33 Year 2009, especially Article 7 which regulates the age classification of the audience.

Current technological developments greatly influence construction projects, both in material procurement and contract models. Specifically for dealing with natural disasters with short recovery times, a Design and Build contract model is used. In the Pangsan Bridge Construction Project, the contractor procured precast concrete beams (Girders) which were produced at the factory and the installation process was carried out at the project. This contract is determined by direct appointment and this Regulation has been issued in PERPRES No. 54 of 2010 Article 38 Paragraph 1 stipulates that direct appointment of 1 (one) provider of Construction work/Other Services can be done in the case of exclusive circumstances; and/or Procurement of special goods/specific construction work/other services of a special nature. The precast concrete girder beam measures 0.65 m x 0.90 m with a length of 15.6 m, and is molded into 3 parts whose strength has been calculated. In terms of processing time, it is faster and costs more than conventional concrete. With production outside the project completion time is 1,5 months faster at a higher cost of 4,5 billion The length of conventional concrete is due to the implementation method which must be sequential and interrelated with a smaller cost of 3,8 billion So to meet the short time, the precast method is used even though it costs more.

Published: March 2024

One of the very common negative effects experienced by operators and workers of sewing machines is neck pain. The use of sewing machines in a forward-leaning position over an extended period of time contributes to neck strain and promotes bad postures like the Forward Head Posture (FHP). The objective of this study was to determine the prevalence of FHP and neck pain among sewing machine operators in tailors and garment factories of District Swabi, Pakistan. This cross-sectional study was carried out on a total of 223 users of sewing machines while seated (97 women and 126 men). The study was conducted in Swabi District from October 2022 to February 2023. The outcomes were evaluated using a numerical pain rating scale and the Neck Disability Index (NDI). According to the Numerical pain Rating Scale (NPRS) for neck pain, 24 participants (10.8%) reported mild discomfort, 79 participants (35.4%) reported moderate pain, and 120 participants (53.8%) reported severe pain. Only 13.9% (n=31) of the participants (n=192) had a normal head position. The majority of the participants were hunched forward. The NPRS had a mean of 3.43 (± SD 0.49), the NDI mean was 3.43 (± 0.68), and the cranial vertebral angle (CVA) mean was 1.13 (±SD 0.34). According to the findings of the current study, FHP and neck pain are quite common among individuals who use sewing machines, and a large percentage of these people also have FHP and neck discomfort.
Juntos por um futuro sustentável: construindo uma agenda de mudanças climáticas entre Brasil e África
Authors: Matos Pedro Andrade
Published: March 2024

É importante repensar a agenda das negociações sobre as mudanças climáticas, porque esta, no formato atual, não interessa aos países africanos, ao não colocar os problemas do continente no centro da discussão nem absorver as contribuições e as contrapartidas das nações africanas ao enfrentamento das mudanças climáticas. O artigo visa entender como a cooperação entre Brasil e África pode contribuir para a construção de um futuro mais sustentável e para a mitigação dos impactos das mudanças climáticas em ambas as regiões, dotadas de imensa biodiversidade e diversidade étnica, cujos povos originários preservam uma relação harmoniosa com a natureza. Para a construção desta agenda, o artigo busca analisar a identificação das prioridades de cada região, as suas experiências e boas práticas, as estratégias de cooperação e de governança climática, bem como a promoção das ações conjuntas na esfera internacional.

Published: March 2024

In both India and globally, all three sectors play pivotal roles in GDP production. The service sector, among them, has exhibited notable growth in recent years. An integral segment within the service and industrial domains is the tourism industry, which has flourished over an extended period, presenting ample opportunities for related sectors. India's economic advancement has significantly benefited from its thriving tourism industry, which attracts a substantial influx of domestic and international travelers for both business and leisure purposes. Beyond contributing to the revenue of towns and nations, tourism fosters local employment opportunities and showcases India's rich heritage sites, festivals, and natural landscapes, all of which are highly esteemed by visitors. For numerous years, natural and human-induced disasters have adversely impacted the nation's tourism sector. People bear the brunt of these calamities, experiencing severe disruptions in their social and economic lives. The states of Uttarakhand and Himachal Pradesh, known for their vibrant tourism industry, fall within India's disaster-prone zones. A robust economy is vital for the tourism sector, which is relatively susceptible to fluctuations, to flourish. The response of the tourism industry to such disasters underscores its vulnerability to abrupt changes in the local economy. This thesis underscores prior research indicating that both natural and human-induced disasters can detrimentally affect employment within the tourism sector. Focusing predominantly on economic ramifications, the paper delves into disasters occurring over the past two decades, with particular emphasis on the significant impact of the 2023 floods in Himachal Pradesh, which reverberated across northern India. Seniors' exposure, sensitivity, and capacities when combined with potentially dangerous situations might severely impair their ability to function normally. It affects people in a socioeconomic, psychological, and physical way. The Depending on their age group, the disaster's impact could be different in degree.
Migration as Mission: Alojz-Alexis Strýček SJ in Belgium (1938–1945)
Authors: Coudenys Wim
Published: March 2024

This article presents a case study of Alojz-Alexis Strýček SJ, a Slovak Jesuit in Belgium during World War II, to examine the complexities of migration, identity, and religious mission within turbulent historical contexts. Strýček’s experiences challenge conventional categorizations in migration studies, demonstrating how individual narratives can intersect with and transcend national and religious boundaries. The study employs social network analysis and philological-historical methods, offering insights into the dynamic roles migrants play in the circulation of knowledge and in shaping transnational connections. Strýček’s case highlights the importance of considering non-national factors, such as religious affiliations, in understanding migration patterns and migrant identities. This research contributes to the emerging field of “migrant knowledge,” which focuses on the role of migrants in global knowledge exchange and the redefinition of identities in times of crisis, thereby enriching our understanding of the multifaceted nature of migration.

We use SEDz*—a code designed to chart the star formation histories (SFHs) of 6 < z < 12 galaxies—to analyze the spectral energy distributions (SEDs) of 894 galaxies with deep JWST/NIRCam imaging by JADES in the GOODS-S field. We show how SEDz* matches observed SEDs using stellar-population templates, graphing the contribution of each epoch by epoch to confirm the robustness of the technique. Very good SED fits for most SFHs demonstrate the compatibility of the templates with stars in the first galaxies—as expected, because their light is primarily from main-sequence A stars, free of post-main-sequence complexity, and insensitive to heavy-element compositions. We confirm earlier results from Dressler et al. (1) There are four types of SFHs: SFH1, burst; SFH2, stochastic; SFH3, “contiguous” (three epochs), and SFH4, “continuous” (four to six epochs). (2) Starbursts—both single and multiple—are predominant (∼70%) in this critical period of cosmic history, although longer SFHs (0.5–1.0 Gyr) contribute one-third of the accumulated stellar mass. These 894 SFHs contribute 1011.14, 1011.09, 1011.00, and 1010.60
M
⊙ for SFH1–4, respectively, adding up to ∼4 × 1011
M
⊙ by z = 6 for this field. We suggest that the absence of rising SFHs could be explained as an intense dust-enshrouded phase of star formation lasting tens of Myr that preceded each of the SFHs we measure. We find no strong dependencies of SFH type with the large-scale environment; however, the discovery of a compact group of 30 galaxies, 11 of which had first star formation at z = 11–12, suggests that long SFHs could dominate in rare, dense environments.
