Published: January 2024

Abstract
Enhancing agricultural production quality is a crucial role of nitrogen fertilization. Generally, the utilization of nitrogen fertilizer can promote plant growth, impart a more intense green hue to leaves and stems, and significantly augment biomass production. However, excessive application of nitrogen fertilizers can result in substantial cultivation cost increase and serious environmental degradation. Hence, it’s important to regulate the nitrogen content within the soil. The primary goal of this research is to employ the NIRS technique to rapidly and eco-friendly predict soil nitrogen content. Soil samples were obtained from farmlands situated in the Aceh Besar district, with spectral data gathered within a wavelength range of 1000 – 2500 nm at 0.2 nm intervals.. NIRS and Partial Least Square (PLS) spectrum data were used to make a prediction model of the nitrogen harvesting element. The results showed that the PLS method with SNV (R=0,72) and BSC (R=0,73) pretreatment showed predictive model capabilities that were almost the same as the raw data (R=0,75), although there was a slight improvement, this suggested that nitrogen elements in Aceh Besar region have not or can use the model with the suggestion to increase the amount of data and improve the treatment of the soil harvester method so that the nitrous content elements present in the ground do not easily evaporate so as to provide better model prediction results.

Abstract
The Internet of Things (IoT) has experienced considerable expansion and development in recent years, offering a multitude of prospects for technological progress in the agricultural sector, with the aim of improving efficiency and providing help to farmers on a global scale. This paper outlines the conceptualization and development of an smart sprinkle irrigation system that incorporates the Internet of Things (IoT) technology, leveraging the ESP32 platform. The aim of this study is to develop a smart irrigation-based internet of things utilizing multiple sensors for sprinkle irrigation system. This will be achieved by integrating several sensors to monitor and control the irrigation process. The facilitation of communication between the ESP32 device and the Blynk application simplifies the acquisition of irrigation data, initiation of plant watering, deactivation of the automated watering functionality, and generation of graphical representations derived from sensor measurements. The irrigation system that has been created encompasses three distinct ways, particularly manual, semi-automatic, and automatic. The manual irrigation method enables users to directly administer irrigation, but the semi-automatic method necessitates users to select the timing and length of watering. The automated approach employs irrigation systems that are capable of responding to soil moisture levels, triggering the activation of the pump when the moisture content decreases beyond a predetermined threshold. The device is equipped with a pH sensor that enables the monitoring of soil pH values, a critical factor in facilitating optimal plant growth and development. The system has the capability to present the rate at which water flows and the total amount of water utilized in a singular irrigation event, as well as to aggregate the water consumption across many irrigation instances. In general, the experiments demonstrate the satisfactory performance of the three irrigation systems, including the capability to manually initiate the pump.

Abstract
Land management by combining annual crops with seasonal crops is known as agroforestry. Agroforestry has a positive impact on watershed sustainability as it improves the watershed ecologically, economically, and socially. Coffee agroforestry is an agroforestry that incorporates coffee plants in their system. Coffee agroforestry in the Upper Ciliwung Watershed is spread across several sub-watersheds, but there is conflicting information related to the distribution and extent of agroforestry which results in no precise information on the coffee plants distribution. Therefore, this study aims to map the distribution and extent of coffee agroforestry in the Upper Ciliwung Watershed and identify the composition of the agroforestry system in the Upper Ciliwung Watershed. This study is done through satellite imagery interpretation and ground truth check of coffee agroforestry in the study area. The data are analyzed using descriptive qualitative method to describe obtained information on the coffee agroforestry from field observation. The results show that there are four sub-watersheds that have coffee agroforestry in the Upper Ciliwung Watershed, which are Cibulao, Cisuren, Cikoneng, and Rawa Gede sub-watersheds. Cibulao sub-watershed has a coffee agroforestry area of about 20 hectares, Cisuren has an area of about 32 hectares, Cikoneng has an area of about 5 hectares, and Rawa Gede has an area of about 5 hectares. In total, the coffee agroforestry areas in the Upper Ciliwung Watershed are approximately 62 hectares.

Published: January 2024

Abstract
This research aims to develop a polyurethane foam (PUF) adsorbent with solid tofu waste (TW) filler. TW was activated using NaOH at concentrations ranging from 0.2 M to 0.6 M. The PUF was synthesized by combining polyol with isocyanate. The TW PUF adsorbent was employed for removing Pb(II) and Cu(II) from aqueous solutions. The results revealed that the adsorption efficiency of TW PUF-0.2 M for Pb(II) removal was 60.36%, while TW PUF-0.4 M and TW PUF-0.6 M showed the adsorption efficiencies of 63.26% and 61.39%, respectively. Similarly, the adsorption efficiency for Cu(II) removal was 62.45%, 65.93%, and 63.34% for TW PUF-0.2 M, TW PUF-0.4 M, and TW PUF-0.6 M, respectively. Despite the insignificance in the change of adsorption efficiency with NaOH concentration, the optimal activation concentration for TW was found to be 0.4 M. In conclusion, TW PUF adsorbent exhibits potential for adsorbing Pb(II) and Cu(II), and its production can contribute to minimizing the environmental impact of tofu waste.

Published: January 2024

Abstract
The surface, a layer directly under tire load, is often made of crushed aggregate, gravel, or recycled materials. In order to extend the operational lifetime of the road, the surface serves as higher properties of materials. The impact of performance for the surface layer on the design life was examined in this research. Employing the KENPAVE software, the study examined the impact of changing the thickness of the surface layer (2″, 2.5″, and 3″) and the resilient modulus (300, 400, and 500 ksi) on the expected service life of the flexible pavement for both repeated loads 30000 and 40000. The results show that the increased surface layer thickness lead to the increase in pavement design life for all resilient modulus and both repeated loads. The percentage of increase of design life of pavement grew as the resilient modulus grew (for all repeated loads). As resilient modulus of surface layer increased, so did the pavement design life increase. The percentage of increasing the design life of pavement results from increased resilient modulus was increased with the increasing thickness layer. The percentage of improvement the design life of pavement caused by increase of resilient modulus, increase with increase the surface layer thickness (for all repeated loads).

Abstract
Pantura road at estuary of Sayung River is often flooded because it has a lower elevation than the river embankment. To avoid this, we must know the flood capacity of the river so that we can plan flood control and maintenance of river channels. Usually in flood prevention planning, it only design structure with unsteady flow model without sediment transport analysis. It is contrary with river nature because bed and river bank will easily erode, then transported as sediment and deposited in the lower reaches of the river. It makes river geometry will vary along with increasing of sedimentation. Therefore, capacity of the river will be analyzed with sediment transport using HEC-RAS 6.2 quasi unsteady flow model. Based on transport sediment simulation, sediment material deposition at Sayung River is 45,000 m3 every year. It makes river capacity decreased. Sayung River capacity is currently 242.15 m3/s, in 2023 is 200 m3/s, in 2024 is 185m3/s, in 2025 is 170 m3/s, year 2026 is 155 m3/s, in 2027 is 140m3/s, in 2028 is 120m3/s, in 2029 is 100m3/s, in 2030 is 77.5m3/s.

Published: January 2024

Abstract
Nutrient diagnosis can be a guide for optimizing growth through proper fertilization. This study aims to quickly evaluate the response of the patchouli plant to nutrient stress in Inceptisols. That was carried out through a greenhouse experiment consisting of 8 fertilizer nutrient treatments. Two treatments were used as control, namely without application of fertilizer (Co) and complete macronutrients (C). The other six treatments were the addition of complete macronutrients without N (C-N), -P (C-P), -K (C-K), -Ca (C-Ca), -Mg (C-Mg), and -S (C-S) respectively. The fertilizer dose used is half of the recommended dose (128.8 kg N; 25 kg P2O5; 84 kg K2O; 81 kg Mg; 117.4 kg Ca and 60 kg S ha-1). Experiment using a randomized block design with 3 replications. The patchouli seed tested was the local variety. Patchouli plant responses observed were plant height, number of main branches, leaf characteristics, and biomass. Fertilization treatment is not significant to the growth of patchouli. Treatment without fertilizer, complete without N, complete without K, and complete without P showed lower patchouli growth and production. Fertilizer treatment without N tends to show the lowest growth response on each parameter. Nitrogen is the main nutrient-limiting factor for patchouli plants in Inceptisols Aceh.
