<![CDATA[High voltage deviation, State of charge (SOCs) divergence, and inappropriate load/power sharing are some challenges that DC microgrids face. These problems can be rectified easily if the control algorithm is designed based on the other units' data. However, utilization of communication links has some disadvantages which make them improper in many cases. Regarding that, in this paper, a novel communication-free control method is presented. In this method, the droop gain is divided into two parts. The first part of the droop gain is selected according to the line resistance in such a way, that the effect of line resistance on current sharing is omitted, while the second part is considered for balancing SOCs. Regarding that, it is defined as a function of SOC such that the higher SOC unit injects more and absorbs less current. Comparing the simulation results of the proposed method with other methods proves that the proposed method can balance SOCs and reduce the DC bus voltage deviation like the SOC-based method. Besides, it can share current properly like the virtual resistance method.]]>

<![CDATA[This research explores the significance of field trocars in land reclamation within Karbala Governorate's Karta-10 area, caused by waterlogging and salinity. Implementing a detailed reclamation strategy, the study underscores the necessity of a 2 to 2.5 meters burial depth for trocars to prevent water and salt-related issues, aligning with industry standards. The investigation discourages reducing trocar depth to cut costs, as it can result in capillary action and salt build-up or require deeper drainage to manage seepage. Findings indicate that shallow trocars reduce water storage capacity, impacting irrigation and crop hydration, whereas deeper trocars offer better management of drainage flow and spacing efficiency. The study indorses a universal trocar depth of 2 to 2.5 meters, accommodating various crops, thus guiding optimal trocar design and placement for effective land reclamation.]]>

<![CDATA[The high pedestrian activity and traffic flow in the education area on Jalan Raya Abepura-Sentani Jayapura City led to the provision of Pedestrian Bridges (JPO) in two locations, namely in front of the Cenderawasih University Auditorium (JPO-1) and in front of SMP YPPK Santu Paulus (JPO-2). This research was conducted to determine the suitability of the physical geometric standards of the pedestrian bridge and its level of effectiveness, as well as factors that affect pedestrian satisfaction in using the two Pedestrian Bridge (JPO) facilities. Geometric analysis was carried out using the standard of Pedestrian Bridge Planning Procedures for Urban Pedestrians (1995) and Technical Planning of Pedestrian Facilities (2023), calculation of the level of effectiveness using the volume of crossings, and analysis of service satisfaction using the Importance Performance Analysis (IPA) method. The results found that the condition of JPO-2 is better and meets the standards because it uses a slope that can be used by people with disabilities, while the slope on the steps of JPO-1 is too steep (40°) and narrow with a width of 1.4 meters, so the effectiveness level of JPO-2 is higher (67%) than JPO-1 (52%). Factors affecting user satisfaction are aspects of comfort, safety, and security. The main obstacles in using the pedestrian bridge are dirty conditions, no lighting, the presence of people under the influence of alcohol or extortionists, and damage to the Pedestrian Bridge (JPO) facilities.]]>

<![CDATA[The tofu industry in Indonesia generally utilizes simple processing technologies, leading to unresolved wastewater management issues. Tofu wastewater contains high organic matter, measured by BOD, a parameter indicating the oxygen required by microorganisms to decompose organic matter. High BOD can decrease dissolved oxygen (DO) levels in water, which is crucial for aquatic life. This study investigates the effectiveness of local probiotics in reducing BOD and increasing DO in tofu wastewater (ABIT). Three treatments were applied: pure ABIT, neutralized ABIT (ABIT-N), and ABIT mixed with local probiotics in three ratios (1:1, 1:2, and 1:3). DO was tested at 0, 8, 16, 24, and 36 hours, while BOD was tested at 0 and 5 days. The results demonstrate that local probiotics can effectively reduce BOD and enhance DO levels in ABIT. The highest DO (3.36 mg/L) was observed in ABIT-N mixed with local probiotics at a 1:3 ratio after 32 hours. The most significant BOD reduction (135.77 mg/L) was also achieved at the 1:3 ratio. These findings suggest that local probiotics offer an eco-friendly approach to treating tofu wastewater.]]>

<![CDATA[Indonesia boasts a number of tofu processing facilities totaling, around 84,000 both scale and large scale operations. These facilities collectively consume 2.56 million tons of soybeans each year. The high volume of tofu production poses a threat to the environment due to the generation of waste. If this waste is directly released into water bodies it can alter the waters characteristics potentially harming life. To address this issue Tofu Industry Wastewater can be implemented by introducing probiotics containing microorganisms that aid in breaking down matter and other components in the waste. This study focuses on analyzing bacterial colonies in Tofu Industry Wastewater by examining bacterial colonies present in these products. Various mixtures of Tofu Industry Wastewater and commercial probiotics will be tested at ratios of 1:1, 1:2, 1:3, and 1:4 over time periods ranging from 24, 48, 72, 96, 120, and 144 hours. The findings indicate that incorporating probiotics into Tofu Industry Wastewater can lead to a reduction in pollution levels.]]>

<![CDATA[This study aims to analyze the impact of administering commercial probiotic bacteria on the wastewater from tofu industries on changes in Bio-logical Oxygen Demand (BOD) and Dissolved Oxygen (DO) levels. Tofu industry wastewater is known to have high BOD and low DO levels, which pose a potential environmental pollution risk. This study used a pure experimental method with variables including the ratio of tofu industry wastewater to commercial probiotics (1:1, 1:2, 1:3) with an incubation interval of 8 hours. The results showed that the administration of commercial probiotic bacteria significantly reduced BOD levels and increased DO levels in the wastewater. The 1:3 ratio of tofu industry wastewater to commercial probiotics showed the most optimal effect in increasing DO and decreasing BOD. An incubation time of 32 hours showed the most optimal effect in increasing DO and decreasing BOD. The 1:3 volume ratio between tofu wastewater and probiotics (25% tofu wastewater and 75% probiotics) proved to be the most effective, with the highest DO increase of 2.51 mg/L and the largest BOD decrease of 144.20 mg/L. In addition, incubation time also had a significant effect, the longer the incubation time, the more optimal the probiotic activity in reducing BOD levels and increasing DO levels. The conclusion of this study is that the administration of commercial probiotic bacteria at a 1:3 ratio and an incubation time of 32 hours is an effective way to improve the quality of tofu industry wastewater.]]>
