Authors: Rendi Dinova  , Annisa Febrina  
Published: January 2025

Fertilizer is a substance or material that is used in plants to improve physical, chemical, or biological characteristics in order to increase the availability of nutrients, which results in an increase in plant growth. There are two types of fertilizer in Indonesia: subsidies and non-subsidized. While subsidies are provided by the government, non-subsidized are those that are provided outside of government programs and do not qualify for subsidies. Non-subsidized fertilizers, although they have superior quality and technology compared to subsidized fertilizers, still face problems in terms of farmers' Purchase Intention, especially in Kecamatan Bahorok. The purpose of this study is to examine the effects of cultural, social, and private factors on the desire to purchase intention non-subsidized fertilizer at Toko UD. Sejahtera Bersama in Kecamatan Bahorok. Data collection using a questionnaire given to 90 respondents. The model used is multiple linear regression and is processed using SPSS. The results of this study indicate that cultural factors partially do not have a positive and significant influence, social factors partially do not have a positive and significant influence and personal factors partially have a positive and significant influence. The Adjusted R Square value of 0.541 means that Purchase Intention
can be explained by cultural, social and personal factors by 52.5% and the remaining 47.5% can be explained by other variables not studied.

Published: January 2025

Scrubber atau sering disebut juga sebagai "scrubber kapal", adalah perangkat yang digunakan pada kapal untuk mengurangi emisi gas buang dari mesin pembakaran internal yang menggunakan bahan bakar berbasis minyak, sepertidiesel atau bunker fuel. Exhaust gas cleaning systems (EGCS) scrubber menjadi teknologi yang lebih sering digunakan kapal untuk mencapai kepatuhan terhadap batas sulphur. Scrubber ini bertujuan untuk mengurangi emisi gas sulphur dioksida (SO2) pada nilai ambang batas 0.5% kandungan gas buang. Sulfur dioksida adalah salah satu spesies dari gas-gas oksida sulfur (SOx). Gas ini sangat mudah terlarut dalam air, memiliki bau namun tidak berwarna, SO2 dan gas-gas oksida sulfur lainnya terbentuk saat terjadi pembakaran bahan bakar fosil yang mengandung sulfur. Optimalisasi berasal dari kata optimal berarti terbaik, tertinggi. Metode yang digunakan pada penelitian ini adalah metode kualitatif deskriptif. Penelitian kualitatif adalah penelitian yang bersifat deskriptif dan cenderung menggunakan analisis. Landasanteori dimanfaatkan sebagai pemandu agar fokus penelitian sesuai dengan fakta dilapangan. Seperti peraturan IMO (Organisasi Maritim Internasional) yang membatasi kadar sulphur dalam bahan bakar kapal. Peneltian kualitatif adalah penelitian yang bersifat deskriptif dan cenderung analisis. Proses dan makna dimanfaatkan sebagai pemandu agar focus penelitian sesuai dengan fakta di lapangan. Penelitian ini adalah tentang optimalisasi Scrubber dalam menurunkan kadar sulphur dioksida di kapal MV. CMA CGM ELBE. Penyebab CEMS (continuous emission monitoring system) mengalami alarm out of compliance dikarenakan penurunan ph yang drastic. Ph yang tinggi dibutuhkan untuk mengikat kandungan Sulphur pada gas buang. Penurunan ph ini disebabkan bocornya pipa tanki air kapur karena terjadi penyumbatan pada pipa. Pressure pompa yang tinggi, dan adanya penyumbatan menyebabkan pipa mengalami kebocoran. Perawatan yang dilakukan adalah melakuka system bubling untuk menjaga pengendapan air kapur pada tangka. Serta melakukan flushingline dengan air tawar agar tidak ada air kapur yang tersisa pada pipa untuk menghindari penyumbatan.

Published: May 2023

ImportanceThe association of early diagnosis and management of bipolar disorder with adolescent suicide mortality (ASM) is unknown.ObjectiveTo assess regional associations between ASM and bipolar disorder diagnosis frequencies.Design, Setting, and ParticipantsThis cross-sectional study investigated the association between annual regional ASM and bipolar disorder diagnosis rates in Swedish adolescents aged 15 to 19 years in January 1, 2008, through December 31, 2021. Aggregated data without exclusions reported at the regional level encompassed 585 suicide deaths, constituting 588 unique observations (ie, 21 regions, 14 years, 2 sexes).ExposuresBipolar disorder diagnosis frequencies and lithium dispensation rates were designated as fixed-effects variables (interaction term in the case of males). An interaction term between psychiatric care affiliation rates and the proportion of psychiatric visits to inpatient and outpatient clinics constituted independent fixed-effects variables. Region and year comprised random intercept effect modifiers. Variables were population adjusted and corrected for heterogeneity in reporting standards.Main Outcomes and MeasuresThe main outcomes were sex-stratified, regional, and annual ASM rates in adolescents aged 15 to 19 years per 100 000 inhabitants as analyzed using generalized linear mixed-effects models.ResultsFemale adolescents were diagnosed with bipolar disorder almost 3 times more often than male adolescents (mean [SD], 149.0 [19.6] vs 55.3 [6.1] per 100 000 inhabitants, respectively). Median regional prevalence rates of bipolar disorder varied over the national median by a factor of 0.46 to 2.61 and 0.00 to 1.82 in females and males, respectively. Bipolar disorder diagnosis rates were inversely associated with male ASM (β = −0.00429; SE, 0.002; 95% CI, −0.0081 to −0.0004; P = .03) independent of lithium treatment and psychiatric care affiliation rates. This association was replicated by β-binomial models of a dichotomized quartile 4 ASM variable (odds ratio, 0.630; 95% CI, 0.457-0.869; P = .005), and both models were robust after adjusting for annual regional diagnosis rates of major depressive disorder and schizophrenia. No such association was observed in females.Conclusions and RelevanceIn this cross-sectional study, lower suicide death rates in adolescent males was robustly associated with regional diagnosis rates of bipolar disorder at an estimated magnitude of approximately 4.7% of the mean national suicide death rate. The associations could be due to treatment efficacy, early diagnosis and management, or other factors not accounted for.

ObjectiveOur systematic review aimed to investigate the proportion of participants with osteoarthritis who were prescribed nonsteroidal antiinflammatory drugs (NSAIDs) by their health care provider.MethodsElectronic databases were searched for observational studies reporting NSAID prescribing to participants with diagnosed osteoarthritis of any region. Risk of bias was assessed using a tool designed for observational studies measuring prevalence. Random and fixed‐effects meta‐analysis was used. Meta‐regression investigated study‐level factors associated with prescribing. The overall evidence quality was assessed using Grading of Recommendations Assessment, Development, and Evaluation criteria.ResultsFifty‐one studies were included, published between 1989 and 2022, with 6,494,509 participants. The mean age of participants was 64.7 years (95% confidence interval [95% CI] 62.4, 67.0; n = 34 studies). Most studies were from Europe and Central Asia (n = 23 studies), and North America (n = 12 studies). Most studies were judged to be at low risk of bias (75%). Heterogeneity was eliminated when removing studies with a high risk of bias, to give a pooled estimate of NSAIDs prescribing to participants with osteoarthritis of 43.8% (95% CI 36.8, 51.1; moderate quality of evidence). Meta‐regression determined that prescribing was associated with year (decreased prescribing over time; P = 0.05) and geographic region (P = 0.03; higher in Europe and Central Asia and in South Asia than in North America) but not with clinical setting.ConclusionData from over 6.4 million participants with osteoarthritis between 1989 and 2022 indicate that NSAID prescribing has decreased over time and that prescribing differs between geographic locations.

AbstractFunctional conductive hydrogels are widely used in various application scenarios, such as artificial skin, cell scaffolds, and implantable bioelectronics. However, their novel designs and technological innovations are severely hampered by traditional manufacturing approaches. Direct ink writing (DIW) is considered a viable industrial‐production 3D‐printing technology for the custom production of hydrogels according to the intended applications. Unfortunately, creating functional conductive hydrogels by DIW has long been plagued by complicated ink formulation and printing processes. In this study, a highly 3D printable poly(3,4‐ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS)‐based ink made from fully commercially accessible raw materials is demonstrated. It is shown that complex structures can be directly printed with this ink and then precisely converted into high‐performance hydrogels via a post‐printing freeze–thawing treatment. The 3D‐printed hydrogel exhibits high electrical conductivity of ≈2000 S m−1, outstanding elasticity, high stability and durability in water, electromagnetic interference shielding, and sensing capabilities. Moreover, the hydrogel is biocompatible, showing great potential for implantable and tissue engineering applications. With significant advantages, the fabrication strategy is expected to open up a new route to create multifunctional hydrogels with custom features, and can bring new opportunities to broaden the applications of hydrogel materials.

AbstractThe piezoelectric enhancement of photo‐catalytic activity for water splitting and pollutant degradation is a novel approach to developing renewable energy and environmental protection applications. Herein, a new form of defect engineered Na‐Sm bimetallic‐regulated CaBi2Nb2O9 platelet is synthesized via a molten salt process for water splitting and pollutant degradation applications. An intermediate band structure is introduced by Sm‐doping, and empty orbitals in the conductive band are introduced by Na‐doping. These factors, combined with the increased local charge density around the Sm and Na atoms, result in an increased electrical conductivity, improved electron mobility, and provide additional electrons for enhancing catalytic reactions. As a consequence, the judicious co‐doping of CaBi2Nb2O9 with Sm and Na leads to a unique synergetic piezo‐photo‐electric effect to provide a superior piezo‐photo‐catalytic performance for H2 production (158.53 µmol g−1 h−1) and pollutant degradation (rate constant, k = 0.257 min−1). This new approach provides important insights into the application of defect engineering to exploit the cooperative doping of alkaline earth metals and rare metals to create high‐performance catalysts.

Published: May 2023

AbstractAdhesive hydrogels containing quaternary ammonium salt (QAS) moieties have shown attractive advantages in treatment for acute wounds, attributed to their high performances in wound sealing and sterilization. However, the introduction of QAS commonly leads to high cytotoxicity and adhesive deterioration. Herein, aimed to solve these two issues, a self‐adaptive dressing with delicate spatiotemporal responsiveness is developed by employing cellulose sulfate (CS) as dynamic layers to coat QAS‐based hydrogel. In detail, due to the acid environment of wound in the early stages of healing, the CS coating will quickly detach to expose the active QAS groups for maximum disinfectant efficacy; meanwhile, as the wound gradually heals and recovers to a neutral pH, the CS will remain stable to keep QAS screened, realizing a high cell growth‐promoting activity for epithelium regeneration. Additionally, attributed to the synergy of temporary hydrophobicity by CS and slow water absorption kinetics of the hydrogel, the resultant dressing possesses outstanding wound sealing and hemostasis performance. At last, this work anticipates this approach to intelligent wound dressings based on dynamic and responsive intermolecular interaction can also be applied to a wide range of self‐adaptive biomedical materials employing different chemistries for applications in medical therapy and health monitoring.

Chemical Design of Organic Interface Modifiers for Highly Efficient and Stable Perovskite Solar Cells
Authors: Kim Seul‐Gi , Zhu Kai 
Published: May 2023

AbstractPerovskite solar cells (PSCs) have demonstrated rapid progress in their power conversion efficiencies (PCEs)—from 3.8% in 2009 to 25.7% in 2022—and they have received considerable attention as a promising future photovoltaic (PV) technology. However, the operational stability of PSCs is still inadequate to satisfy the standards for commercial applications. Interface engineering has become one of the most important strategies to push PSCs’ efficiency and stability for practical use. Among the various interface engineering approaches, organic interface modifiers (OIMs) have been frequently used by the PSC field to address the issues limiting PSC stability at high efficiency levels. In this perspective, the chemical structures of state‐of‐the‐art OIMs are discussed, and their characteristics are reviewed, as well as the impact on device performance associated with key device interfaces (e.g., metal oxide/perovskite and organic transport layer/perovskite interfaces) from a chemical and materials engineering point of view is discussed. Design considerations and the authors' perspective are discussed, on the basis of representative literature examples, for building new, customized organic OIMs to further improve PSC efficiency and stability toward commercialization.
