Abstract

The accumulation of microplastics (MPs) in agricultural land may threaten food security and farmers' health, which is of interest. This study examined the implication of MPs contamination/pollution on the chemical properties of an Inceptisol on different slopes in the horticultural production center of Banuhampu Subdistrict, Agam District, West Sumatra Province. The soil samples were determined by purposive random sampling with a quantitative survey method. Sample testing was carried out using a randomized completely block design with five treatments, i.e., 25-45% in forests, and 0-8%, 8-15%, 15-25%, and 25-45% in fields at a depth of 0-20 cm. The Inceptisol contaminated with MPs has the following characteristics: pH = 5.01, EC = 0.09 dS m-1, Eh = 92.97 mV, mineral = 68.81%, OM = 31.19%, CEC = 60.67 cmol(+) kg-1, C = 2.13%, N = 0.81%, P2O5 = 6.46 ppm, K = 0.48, Ca = 1.59 cmol(+) kg-1, Mg = 0.62 cmol(+) kg-1 , and SO4 = 98.98 ppm. The concentration of MPs on the Inceptisol was 438.33 particles kg-1 with filament shape, transparent color, and large size (1-5 mm) were the most commonly found. Polymer types included polyamide 6, polystyrene, and polyethylene. The effect of slope level on the surface change charger of Inceptisols contaminated with MPs was insignificant. However, the effect was significant in OC, total N, K-exch, and available S. The implications of microplastic contamination/pollution did not have a significant relationship with the chemical properties of the soil. However, it has a negative relationship to redox potential (Eh), mineral composition, and Ca-exch.

Abstract

The quality of biochar produced through the pyrolysis process depends on the combustion temperature, duration of combustion, and the raw materials used. Biochar is a carbon-rich product resulting from the thermal decomposition of organic matter. Biochar from bamboo and pinewood was produced at 400 and 800 using a closed chamber where the temperature could be set. Biochar is made through carbonization with pyrolysis. This study aimed to find out the functional group characteristics of two types of raw materials, bamboo and pine wood. This research was conducted at the Environmental Soil Physics Laboratory, Universitas Syiah Kuala. Two types of feedstocks, bamboo, and pinewood, were used as sample experiments. The feedstocks were burned inside a closed chamber with no oxygen present. (Thermo scientific thermolyne F4820-33). The temperature was at 400 and 800, and a burning time of four hours. Fourier Transform Infra-Red (FTIR)was used to characterize the functional groups of biochar tested. Our research showed biochar from pinewood burned at a temperature of 400 gave the characteristics of the functional groups OH, CH, and C=O with strong intensity. It indicates that there was decomposition of organic matter into organic compounds taking place.

Abstract

Biochar is a by-product produced from the combustion process without oxygen at high temperatures (100-800oC) for approximately one hour. The advantage of this biochar is that apart from having several distinctive properties such as being more efficient, cost-effective, and easy to obtain, it can also improve the soil physical properties and remove toxic contaminants in ex-coal mining soil. Through its large surface area, large pore size distribution, particle types and low density, biochar can influence soil porosity, soil consistency, improve soil aggregate stability values and increase water availability for plants by up to 130%. The research was carried out at the experimental site of the Agriculture Faculty, Universitas Syiah Kuala using planting media from ex-coal mining soil. This research used a factorial randomized block design with three replications. The first factor was the biochar feedstock consisted of pine wood and sawdust. The second factor was the biochar dosage consisted of 0, 10, and 20 tons ha-1. The physical soil characteristic parameters observed were soil porosity, bulk density, and aggregate stability. The biochar characteristic parameters observed were biochar combustion results, biochar morphology, water holding capacity, and biochar bulk density. Pine wood and sawdust biochar can improve soil physical properties, especially soil porosity, but did not affect soil bulk density and soil aggregate stability. Biochar dosages of 10 and 20 t ha-1 can improve soil porosity. However, to minimize costs, the biochar application at a dose of 10 t ha-1 can be recommended.

Abstract

This study aims to analyze the impact of digital technology on marketing strategy development and its effect on the competitiveness of Micro, Small, and Medium Enterprises (MSMEs) in Indonesia. In an era of rapid digitalization, adopting digital technology has become a crucial factor in enhancing the competitiveness of MSMEs. The research utilizes a quantitative approach with a survey design, where data was collected through questionnaires distributed to 100 MSME entrepreneurs who have integrated digital technology into their marketing strategies. The findings indicate that using social media and e-commerce platforms significantly contributes to increased brand awareness, sales, and customer loyalty for MSMEs. Approximately 68% of respondents reported a sales boost after utilizing digital platforms, while more than 60% noted enhanced brand visibility. On the other hand, despite the great potential of SEO and email marketing to improve competitiveness, the application of these strategies remains limited. Multiple linear regression analysis suggests that the more intensively digital technology is used, the greater the competitiveness of MSME products in an increasingly competitive market. These findings emphasize the importance of integrating digital technology into MSME marketing strategies to strengthen their position in domestic and global markets. Therefore, MSME entrepreneurs are encouraged to expand their understanding and implementation of additional digital marketing strategies and seek more significant support from the government and related institutions.
