Abstract

Utilization of Arbuscular Mycorrhiza (MA) as beneficial soil microbes is expected to support nutrient demand for improving crop performance. However, under the agroforestry system that facing a problem on light, water, and nutrients competitions, the role of MA is becoming unclear. The purpose of this research was to examine how far different management in Coffee Pines Agroforestry System (CPAS) affects MA structure and compositions. The relationship between soil parameters (e.g. pH, soil organic C) and MA activities was also being evaluated. The selected plot according to existing management practices were chosen as follows: (1) Low management (LC); (2) High management which then compared to (3) Business As Usual (BAU) plot in which were repeated in triplicate. ANOVA and multivariate analysis were employed to determine the effect of the treatments. The result showed that there were significant differences (p<0.05) in the structure and composition of the MA, in terms of the total number of MA spores and the abundance of Glomus sp. under the coffee tree sampling point, while the lowest number was detected in Gigaspora sp. genera. The more intensive land management resulted in a higher abundance of MA biomass which then leads to increased soil P and uptake-P along with MA infection.

Abstract

Nitrogen (N) fertilization in coffee agroforestry system requires proper management to increase N use efficiency (NUE) and minimize N losses. This study investigated the impact of different fertilization management on N losses, N uptake, and N storage in a coffee-based agroforestry system. The study was conducted using three types of fertilizer (organic, inorganic, and mixture of organic-inorganic) with three doses (low, medium, and high), and a control treatment (no fertilization), with 3 replications. Soil leachate was collected using lysimeter at 50 cm depth (below coffee root zone) and gas emissions were collected monthly using chamber for 4 months. Soil sample at 0-20 cm depth and leaf sample were also collected. The variables included NH₄⁺ and NO₃ˉ concentration in the leachate and soil, soil N total, N uptake, N emission, N use efficiency (NUE) and partial N balance. Results showed no significant differences in N leaching or plant N uptake across treatments. However, the mixed fertilizer with high dose treatment significantly increased soil N availability while reducing N₂O emissions and improving the overall N balance. This suggests that a high dose mixed fertilizer application can enhance N utilization in coffee-based agroforestry systems, potentially improving productivity while minimizing environmental impacts. Keywords: Agroforestry, Fertilization, Nitrogen balance, Nitrogen loss, Nitrogen storage.

Abstract

Life in this world has been going on for so long. From the hereditary life there has been a shift and inheritance-inheritance be it culture, science, religion, and much more. If the scholars inherited the knowledge possessed by the prophet, then Ustadz can be said to be the one who inherited the science of kiai. After being trained in the crater candradimuka named boarding school of the santri who will become ustad in their respective areas of course have the knowledge that has been given by the teacher. But in life related to economy or worldliness whether ustadz is able to imitate the way used by kiai with his zuhud, because that is done mostly is ngaji and da'wah, while today has entered the modern era, the era of globalization that pivot on the culture of consumptive.

Abstract

This study aims to analyze the effect of system quality, information quality, and service quality on user satisfaction of the T24 application (Temenos Transact Core Banking) with perceived usefulness as an intervening variable, with a case study at J Trust Bank Indonesia. The research sample consisted of 113 respondents who were users of the T24 application. The analysis method used was Structural Equation Modeling-Partial Least Squares (SEM-PLS). The results showed that information quality did not have a significant effect on user satisfaction and perceived usefulness. Service quality had a significant effect on user satisfaction and perceived usefulness, with influence coefficients of 0.430 and 0.448, respectively. In addition, system quality had a significant effect on perceived usefulness (0.353), but did not have a direct effect on user satisfaction. Perceived usefulness was shown to have a significant effect on user satisfaction (0.268). The mediation relationship through perceived usefulness on user satisfaction shows that information quality, service quality and system quality do not have a significant effect with each P-Value of (0.428), (0.066) and (0.065). This study reveals the importance of service quality as a major factor in increasing user satisfaction with the support of system quality to strengthen the perception of the benefits of using the T24 application.

Phenolics extract was obtained from varions of aquadest and 40;60; 80% methanol. The solution without extract was used as sensitizer, while the extract without illumination wasused as control. Green mustard was packed into medium polybag within it added by 2,000 mg kg-1. Soil type assample was volcanic soil in various categories, such as: soil-extract, soil NPK fertilizer extract, and soil control.Results of Ferro analysis in the clove leafs treated with 80% methanol indicated the highest increasing Fe2+ of 22.94mg kg-1. Rice straw treated with 60% methanol showed the highest increasing Fe2+ of 34.5 mg kg-1. The waterhyacinth leafs treated with 60% methanol obtained the highest increasing Fe2+ of 17.67 mg kg-1. Fe2+ concentrationat soil-clove leafs had the highest increasing of Fe2+ production for 5.6 mg kg-1. Its concentration at soil NPKfertilizer extract water hyacinth leafs showed the highest increasing of Fe2+ production for 13.39 mg kg-1. Highestconcentration of Fe2+ in the green mustard at soil NPK fertilizer extract clove leafs was 176.37 mg kg-1.

Abstract

Retakan pada struktur batu bata dapat mempengaruhi kekuatan dan stabilitas bangunan. Deteksi dini terhadap retakan ini sangat penting untuk mencegah kerusakan lebih lanjut dan menjaga keselamatan bangunan. Dalam penelitian ini, antena mikrostrip digunakan sebagai sensor untuk mendeteksi retakan pada batu bata. Antena mikrostrip dirancang dan diimplementasikan dengan memanfaatkan teknologi gelombang elektromagnetik yang mampu mendeteksi perubahan pada permukaan material. Antena yang digunakan adalah jenis mikrostrip yang dioperasikan pada frekuensi 2,5 GHz. Frekuensi ini dipilih dikarenakan mengikuti standarisasi antena sebagai sensor. Pengujian dilakukan dengan membuat retakan buatan pada batu bata dan mengukur perubahan return loss yang dihasilkan oleh antena. Hasil penelitian menunjukkan bahwa antena tersebut mampu mendeteksi retakan dengan cukup baik. Return loss yang diterima antena menunjukkan perubahan yang signifikan ketika terdapat retakan pada batu bata. Kata Kunci—Antena, Batu bata, Gelombang elektromagnetik, Sensor.
