Published: July 2024

Abstract
Arabica coffee (Coffea arabica L.) has dominated international trade with more than 70% of global coffee production because of it’s taste was more preferred than the other types of coffee. The AS2K clone of C. arabica is a superior clone with high productivity, resistance to pests and diseases, and has a good taste. To maintain these characters, the appropriate propagation is by vegetatively. The aim of this research was to induce callus formation from C. arabica leaves, and to multiplicate the callus on twelve (12) combinations of 2,4-D and BAP as an effort to develop a method for propagating Arabica coffee. Callus induction was conducted on Murashige and Skoog (MS) medium containing 2,4-D 2 mg/L combined with BAP 1 mg/l, and then the multiplication of these callus on MS medium with 12 combinations of 2,4-D (2, 3, or 4 mg/L) and BAP (0, 0.25, or 1 mg/L). The research design used a completely randomized design with 3 replications, and each replication contained 5 callus pieces. The results showed that the combination of 2 ppm 2,4-D and 1 ppm BAP was able to induce callus formation from leaf explants by 49% at week 3 culture, yellowish white in color and friable in texture. Combination of 2,4-D 3 mg/L and BAP 0.5 mg/L provide the best result for callus multiplication.

Published: July 2024

Abstract
Coffee is one of the most popular beverages globally. People often drink coffee for its caffeine content and its stimulating effects. However, excessive coffee consumption, like any other dietary or behavioral excess, can negatively affect physical and mental health. This study investigates the association between excessive coffee use and mental problems. A cross-sectional study was conducted among 392 respondents in Aceh, Indonesia. Excessive coffee use was measured using a questionnaire, while mental illness was screened using DASS-21. Other sociodemographic variables were also examined and treated as possible predictors. The prevalence of excessive coffee use (>400 mg per day) was 15.6%. The prevalence of depression was 23.2%, anxiety was 40.8%, and stress was 12.8%. The amount of caffeine consumption was correlated with depression (rs
= 0.11, p = 0.01), anxiety (rs
= 0.13, p = 0.001), and stress (rs
= 0.14, p = 0.001), indicating that as the amount of coffee consumption increased, the score of mental problem also increased. The study established a noteworthy correlation between caffeine intake and mental health, suggesting that as coffee consumption increased, so did the scores for depression, anxiety, and stress. These findings underscore the importance of considering coffee consumption habits and their potential impact on mental well-being in clinical and public health contexts.

Published: July 2024

Abstract
Cigarette waste is a persistent environmental problem that requires innovative solutions due to the inadequacy of traditional recycling methods. This paper explores the conversion of cigarette butt filters (CBFs) into raw material for cellulose acetate (CA) membrane production. This study prepared two types of membranes: 12% CBF and 12% CA as a control variable. The resulting material was evaluated for its properties and performance as an ultrafiltration membrane for organic contaminant removal. The result demonstrates that the CBF-based membrane exhibits superior characteristics to a CA-based membrane. This improvement is evident in the increased presence of hydroxyl (-OH) groups and enhanced porosity CA 18,37% and CBF 19,66%. Furthermore, the permeability of the CBF membrane has also increased, making it an efficient tool for maintaining humic acid removal CBF 79,02% and CA 66,18% while achieving a high flux ratio recovery CA 65,25 % and CBF 87,97%. The findings in this paper emphasize the promising potential of reusing cigarette waste as an eco-friendly membrane with high humic acid rejection and good antifouling properties.

Abstract
Macroalgae are polyphyletic multicellular plants that generally inhabit the littoral zone of the seashore. Aceh Province has a coastline stretching along the east, north and west ends of Sumatra Island; thus, various macroalga species may be found. This research aims to study the distribution of macroalga species at four locations on the north-western side of Aceh, including three sites in Aceh Besar District (Lhoknga, Lange, and Ujung Pancu Beaches) and one site in Banda Aceh City (Ulee Lheue Beach). Sampling was done across 50 meters of the seashore and 1 meter towards the sea. The sampling was conducted using a 1×1 meter quadrant transect method with sampling points every 10 meters. The morphology determination shows that five species of macroalga grew at Lhoknga Beach, namely Valoniopsis pachynema, Halimeda opuntia, Turbinaria decurrens, Sargassum plagiophyllum, and Padina australis. Lange Beach had three macroalgae species: Chaetomorpha linum, Laurencia obtusa, and Sargassum plagiophyllum. Meanwhile, Ujung Pancu Beach has four macroalga species: Halymenia durvillei, Turbinaria decurrens, Ulva lactuca and Sargassum plagiophyllum. At Ulee Lheue Beach, five species were found: Gracilaria edulis, Caulerpa taxifolia, Hypnea musciformis, Padina australis, and Acanthophora spicifera. In total, 13 macroalga species were distributed on Aceh’s north-western coast.

Abstract
This study aims to assess the vulnerability of communities in Sungai Pauh, Sungai Pauh Pusaka, and Sungai Pauh Tanjung, Langsa, Aceh Province to tidal flooding, and understand their adaptation strategies and the main socio-economic and environmental contributors to vulnerability. A mixed methods approach combines quantitative vulnerability index calculations with qualitative data from interviews. We assessed the vulnerability index using secondary data sources (population density, gender, vulnerable age, poor population, and disabled population) to evaluate the vulnerability of communities. The 34 key informants represent various levels of society, including village officials, government employees, and the community. High social vulnerability was identified, related to population density, gender, age, poverty, and disability, while economic vulnerability was low due to dependence on fishing. The recommendations include knowledge dissemination, public awareness campaigns, the formation of community groups for flood relief, and infrastructure development, with a focus on channel reconstruction to increase resilience and reduce the impact of tidal floods.

Published: July 2024

Abstract
There are several ways to prevent Covid-19 infection, one of which involves implementing Clean and Healthy Living Behavior or Perilaku Hidup Bersih dan Sehat (PHBS). It is crucial for individuals to receive health education, especially concerning PHBS, as it is a means of avoiding the contraction of the Covid-19 virus. Covid-19 survivors undoubtedly possess valuable real-life experiences gained from their battles against this virus, and these experiences can significantly impact the prevention of positive case transmissions in their surrounding environments. This research aims to investigate the implementation of Clean and Healthy Living Behavior (PHBS) in Covid-19 survivors. This study involved 210 individuals representing households who live in the Kuta Alam, Banda Aceh. This research is based on Lawrence Green’s theory, which identifies three factors influencing people’s behavior: predisposing factors, reinforcing factors, and enabling factors. The chosen analytical method for this research is quantitative, utilizing regression analysis. The research shows that PHBS implementation’s effectiveness (Y) is significantly impacted partially by Predisposing Factors (X1), Enabling Factors (X3), and Reinforcing Factors (X2). The findings of this research can guide policies on Clean and Healthy Living Behavior (PHBS) for Covid-19 survivors and provide reference material for disaster-related fields and future researchers.

Published: July 2024

Abstract
Mosques were created to fulfill the needs of Muslims in prayer, therefore thermal comfort is critical to consider so that the congregation is comfortable and can focus and feel at home while praying. The typology of ancient mosques reflects the community’s traditions and culture, as well as local knowledge values. Natural ventilation, which acts as a natural air exchange mechanism, is one facet of thermal comfort. The Gunong Kleng Mosque, founded in 1927, is one of West Aceh Regency’s ancient mosques. However, design adjustments have been made, such as the installation of wooden boards to on terraced roof. The air flow from the building’s roof is blocked, resulting in inefficient air exchange. The goal of this study is to determine thermal performance and the effect of air movement on thermal comfort at the Old Gunong Kleng Mosque. This study employed a quantitative approach using field measurements of air temperature, relative humidity, and air velocity. An anemometer and a USB data logger were utilized to collect data. Field measurements revealed that ET comfort in the mosque was 78% too hot, 16% warm comfortable, and 6% for optimal comfort. Ansys Fluet simulation with two types of situations was used to forecast air speed, demonstrating that changes in the design of the stepped roof had a significant impact on the air speed within the mosque. When opposed to an open roof, a closed roof slightly lowered the ambient temperature in the prayer room.

Published: July 2024

Abstract
Many researchers state that municipal waste management is a city service that must be provided effectively to all residents to achieve prosperity because this problem has been considered a serious problem facing cities. One alternative to look at the waste problem is to evaluate the waste management system using a dynamic system model. The research aims to evaluate the conditions of waste generation in order to optimize waste management efforts in Banda Aceh. A simulation model was conducted in this research based on a dynamic system using Powersim and Stella software. The treatment carried out include collecting primary and secondary data, creating Causal Loop Diagrams and Stock Flow Diagrams, as well as simulations of waste generation based on existing data spanning the years 2017 to 2022. Results show that Banda Aceh City’s waste generation continues to increase with exponential growth behavior during 2017-2022. Simulation results show that in 2030, this waste will reach 255,043 tons with a waste generation rate of 0.63761 tons per year. Results of dynamic system modeling show a sustainable increase in waste production caused by an increase in population. Model validation analysis shows that AVE and MAVE values obtained were 0.0037 and 0.0631, respectively. These results were considered acceptable since they were both less than 10%.

Published: July 2024

Abstract
Pesticides and herbicides are active chemicals used to eradicate plant pests which constitute contamination if they exceed the threshold for the environment and humans. Molecularly Imprinted Polymer (MIP) is a technique for making polymers that are obtained from cross-linked polymers and have cavities that match the template, where the cavities function as a medium for mechanical interaction of molecules with the same size, shape, structure, and physicochemical properties. The polymer produced from the MIP technique is applied to the surface of the sensor material as an endosulfan detection. This research aims to create an endosulfan MIP to obtain a potentiometric MIP sensor capable of detecting endosulfan. The results showed that the optimum conditions for making MIP endosulfan were obtained with a composition of 6.02 mL of chloroform; 0.025 g endosulfan; 0.9 mL methacrylic acid (MAA); 1.57 mL ethylene glycol dimethacrylate acid (EGDMA); 0.07 g benzoyl peroxide with a heating time of 150 minutes at a temperature of 70 °C. The sensor performance test was carried out potentiometrically and it was found that the MIP endosulfan sensor that was made had sensitivity and stability in the concentration range of 0.01-1.0x10−6 ppm with a lifetime up to 90 days.

Published: July 2024

Abstract
The approach to infrastructure development is conducted on soft clay soil, which introduces the threat of consolidation-induced subsidence. The construction soil must possess adequate bearing capacity and shear strength to withstand the loads imposed on it throughout the construction process. Soil with low shear strength necessitates reinforcement to enhance its bearing capacity. This study aims to investigate the effects of preloading on the settlement behavior of soft soil. Applying clay-filled test containers, the laboratory implements the method through a small-scale model approach. As preloading, an embankment load is applied to the soil. The supplementary weight was incrementally increased by 1 kg, 2 kg, 4 kg, 8 kg, and 16 kg for five days. The sample experiments that were conducted were EgVD-0, EgVD S-17, and EgVd S-29. Consolidation was observed in the outcomes of the EgVD S-17 and EgVD s-29 investigations, surpassing EgVD-0 by 53.69% and 57.19%, respectively. EgVD S-17 of 3.56 cm and EgVD S-29 of 3.92 cm were present along with an EgVD-0 decrease of 1.65 cm.

Abstract
Indonesia is among of the massive coffee producers country in the world. Aceh is the fourth biggest coffee producer in Indonesia. Coffee processing produces a side-product called coffee peel. Apart from coffee, there are other natural ingredients that have antioxidant benefits, such as patchouli which is a typical Acehnese product. Almost 90% of the world’s patchouli oil supply are from Indonesia, 70% of which comes from Aceh Special Region. The patchouli planted in Tapak Tuan, South Aceh Regency is one of the major varieties. The investigation’s goal is to determine and identify the antioxidant compounds in this combination. Combining coffee peel extract and patchouli extract is necessary because this combination can increase the diversity of antioxidant compounds in the combined extract. The 10% coffee peel extract and 1% patchouli extract that have been combined will be examined using gas chromatography-mass spectrometry. There were 36 compounds from this combination, but only twelve compounds were detected to have antioxidant activity. According to the findings in this study, the combination of 10% coffee peel extract and 1% patchouli extract has antioxidant compounds. The antioxidant compounds can be beneficial in dermatology.
