Published: May 2024

Abstract
The sustainability and suitability of water resources are of great importance for maintaining urban populations. The landscapes and environment around urban waters have always been the main focus of maintaining water quality for sustainable water supplies. Early-stage field investigations recognized the influence of land use/land cover (LULC) on water quality. To extend the research scope in spatial and temporal dimensions, remote sensing techniques have been utilized to discover the relationships between LULC and water quality. However, these remote sensing datasets generally had a medium spatial resolution, making them unable to support the fine-detailed land classifications that are critical to explore the water quality in an urban area. Moreover, although more details regarding the land surface are available from the currently-generated high-resolution and very-high-resolution remote sensing images, this land surface information is too complex for the state-of-the-art deep learning approaches and benchmark datasets. This manuscript reports our efforts on developing a framework to explore the fine-resolution relationship between surface water pollution and LULC. To address the cost of computing time and limitations of well-labelled datasets, we employ a foundation model-enhanced approach for water extraction and water-surrounded LULC classification. We propose an estimator of surface water pollution susceptibility to main pollutants based on the surrounding LULCs. Selecting the Future City of Beijing as the study area, based on very-high-resolution remote sensing images, the experiment proved that our proposed approach could effectively map the susceptibility of surface water pollution caused by its surrounding land use and land cover. To our knowledge, the relationship of LULCs and water quality have not been investigated using 0.5 m spatial resolution data. We hope our work can provide a prospective fine-detailed water quality analysis in the community of water environment of remote sensing.
Coherence-mixedness trade-offs

Published: May 2024

Abstract
Quantum coherence constitutes a foundational characteristic of quantum mechanics and is integral to emerging quantum resource theories. However, quantum coherence is severely restricted by environmental noise in general quantum processing, indicated by the loss of information of a quantum system. Such processing can be described by the trade-offs between the coherence and the mixedness. Based on the l
2 norm coherence, conditional von Neumann entropy and Wigner–Yanase skew information, we derive basis-independent constraints on the attainable quantum coherence imposed by the mixedness of a quantum state, which generalize the prior basis-dependent relations, provide fundamental insights into the latent coherence resources present within arbitrary quantum systems that undergo decoherence and quantify the inherent limits on extractable coherence imposed by environmental noise.

Abstract

Amorphophallus muelleri (known as "porang" in Indonesia) can be used as a high-value alternative food source and potentially be a glucomannan production source. Due to its limited production, Indonesia has yet to meet the Amorphophallus muelleri (konjac) flour demand. During growth, konjac plants require sufficient fertilization to increase production and yield large tubers. This study aims to determine the appropriate types and doses of manure fertilizers to enhance konjac plant productivity. The research employed a randomized complete block design with ten treatments using sheep, chicken, and cow manure, as well as a control, with doses of 1.5, 1, and 0.5 kg per plant, repeated four times. The results showed that using manure fertilizers significantly affected the growth of konjac plants, including plant height, stem diameter, leaf width, canopy diameter, and yield. The best dry weight results were obtained using chicken manure at 1 kg per plant (61.33 g) and 1.5 kg per plant (47.64 g). Using sheep, cow, and chicken manure increased konjac tuber yield by 94.95%, 93.55%, and 66.96%, respectively.

Abstract
Biofilm are microbial community that attaches to one substrate and another through EPS. Functional microbes in biofilm can be used as a biofertilizer which increase plant growth by providing nutrients and plant resistance to pathogens due to agricultural environmental degradation. Beside being a biofertilizer, biofilm can be developed as a bioremediation agent. Hexavalent chromium (Cr (VI)) is a heavy metal that is widely used in the leather tanning, pharmaceutical and metallurgical industries, so it is easily found in irrigation and causes agricultural land pollution. Chrome can be toxic to microorganisms, plants, animals and humans, because it is carcinogenic, causes ecosystem damage and has a negative impact on human health. Various techniques are used to remediate Cr (VI), one method that can be used is bioremediation by exploiting the potential of bacteri or fungi incorporated in the biofilm. In this study, the biofilm consisted of bacterial and fungi (BFBF) that were found on the western slopes of Mount Lawu. The Cr (VI) reduction test was carried out at concentrations of 5 and 50 mg L−1. The results showed that the biofilm was able to reduce Cr (VI) up to 1.19 mg L−1within 6 hours.

AbstractDue to its geographical location, Ternate is vulnerable to natural disasters. In times of crisis, the community requires emergency disaster food. Preferably, this food should be sourced from the local area. Sago plates made from cassava, a staple food in the region, are commonly consumed by the people of Ternate. Substituting food ingredients has the potential to enhance sago plate products. In Ternate, fish is a crucial commodity and is widely consumed by the community, particularly tuna due to its high protein and omega-3 content. The objective of this study is to develop a food product wherein yellowfin tuna is used as a substitute for sago plate sigkong. The research is an intervention/experimental study that employs three formulas- F1, F2, and F3- with F1, F2, and F3 containing 10%, 15%, and 20% yellowfin tuna powder, respectively. A hedonic test was conducted to assess the favorability level of the three formulas. The test results indicated that F1, F2, and F3 were “slightly liked to liked,” with a score of 6 to 7 in terms of appearance, color, aroma, texture, and taste. The study’s conclusion is that the F3 formula, containing 20% yellowfin tuna powder, is the most preferred.

Abstract
The agricultural commodity supply chain is unique because it still undergoes metabolism after harvest, so it is easily damaged and depends on the climate and season. The rice supply chain in Indonesia has many stakeholders from upstream to downstream, making it much more complex. The challenge is that many activities make it difficult to trace materials, process flows, and information flows. This condition resulted in an inefficient rice supply chain and no upstream and downstream transparency. This paper aims to provide a proposal for an integrated rice supply chain design based on blockchain technology so that it can increase added value and product competitiveness. Based on the study’s results, the rice supply chain comprises six main stakeholders: farmer groups, collecting traders, the milling industry, distributors, Bulog (National Logistics Agency), and retailers. This paper describes the blockchain technology design to be implemented in the rice supply chain. Blockchain technology has the advantage because the historical information recorded for each stakeholder can be distributed to other stakeholders so that the flow of information can be distributed to all stakeholders, making it more transparent. The application of distributed storage has resulted in blockchain technology having advantages in data storage and security.

Published: May 2024

Abstract
Perusahaan Daerah Perkebunan (PDP) Kahyangan is a Regional Owned Enterprise (BUMD) in Jember Regency which was formed in order to manage plantation commodities in 3 Main Plantations and two Subdivision Plantations. PDP’s profit contribution to Jember’s PAD (Pendapatan Asli Daerah) has continued to decline in recent years. With a target of PAD from plantation products in 2020 of 20 million rupiah, only 20% can be realized (4 million rupiah). Based on the 2023 PDP Kahyangan Jember Strategic Plan, one of the problems causing the opinion deficit is external factors. One of them is the suitability between the potential of the plants planted and the land conditions in a plantation area. Where land suitability, which is the carrying capacity of the land, has a significant effect on crop production. Based on the problems that have been presented, it is necessary to design a GIS-based Decision Support System (DSS), which can provide insight to researchers, practitioners and policy makers regarding the success of managing GIS data for the land suitability evaluation process so that it can increase agricultural productivity. Several stages that will be carried out include data collection, data preparation, and data processing carried out in GIS, then continued with implementation of Decision Support System. The used of agile methods to the application development process ensures that the application is built in a shorter time through the use of continuous iteration and testing thereby ensuring that the DSS implementation on the Web GIS application can run optimally.

Abstract
The growth of the hydroponic vegetable cultivation industry has become the main focus in meeting increasing food needs. However, proper and consistent nutritional management is necessary to achieve optimal results in hydroponic cultivation. This research describes the design of a microcontroller-based portable automatic nutrient mixing system designed to simplify and increase the efficiency of hydroponic vegetable cultivation. This system uses a microcontroller as the system’s brain to regulate nutrient concentrations automatically. The nutrients needed for hydroponic plants, such as liquid fertilizer, humic acid, and macro-micro nutrients, can be measured and mixed according to predetermined parameters. The success of this system is supported by the EC (Conductive Capability) sensors integrated into the system. The advantage of this nutrient mixing system is its portability, which allows users to organize hydroponic vegetable cultivation in various locations without significant limitations. The system can also be monitored and controlled remotely via a mobile app or computer, allowing users to control their plants’ nutrition even when they are away. Experimental results show that this system can produce a consistent nutrient mixture that meets the needs of hydroponic plants. Thus, this microcontroller-based portable automatic nutrient mixing system can effectively support the sustainable and efficient growth of the hydroponic vegetable cultivation industry.

Abstract
As time progresses, oil production will gradually depletes considering limited oil reserves. This is why, an advanced stage method known as tertiary oil recovery is required. One of these methods is known as Enhanced Oil Recovery method. In this laboratory study, one specific surfactant fluid was used, namely Fir wood sodium lignosulfonate (SLS) with varying concentrations of 0.50; 1.00; 1.50; 2.00; 2.50; and 3.00% each crude oil 39 ° API. This study aims to witness the stability of SLS surfactant fluid in chemical injection. SLS surfactant injection is carried out to increase oil production in the reservoir. In this study, there are various stages in order to test the characteristics of the SLS surfactant, so it can be declared as effective in oil sweeping, namely phase behaviour test, density testing, phase behaviour test, interfacial tension test, and adsorption test. Density test is carried out to determine the density of a fluid. Phase behaviour test is intended to see the stability of emulsion obtained from the utilization of SLS surfactant. The main objective of surfactant utilization is to reduce interfacial tension which leads to IFT test. The IFT (interfacial tension) results of the SLS surfactant fluid are determined from the results of the stable phase behaviour test which evidently shows the critical micelle concentration (CMC) point, so it can properly reduce the interfacial tension of oil and formation water in the reservoir. Interfacial tension test was carried out to determine the interfacial tension between SLS surfactant and oil. Adsorption test is carried out to witness the level of fluid adsorption onto the rock surface. On static adsorption test, the result showed for 2 % surfactant concentration is 9.526 mg/gr. Dynamic adsorption test was conducted on the same concentration show results of respectively 1.865 mg/gr.
