Indonesian MSMEs in 2022 will begin to enter the transformational recovery phase. Various preparations must be made in order to adapt. One that has been done is to increase the number of MSMEs entering the digital ecosystem, such as the MSME marketplace. The MSME Marketplace is used for marketing various MSME products online. The MSME Marketplace must be supported by methods that are able to provide good and fast personal services, considering the types and variety of products offered are increasing in number and varying from time to time. Therefore, this study proposes the Porat_Rank method to produce product recommendations that match user interests quickly so that users are served well. The experimental results show that the Porat_Rank method is superior to the Copelan Score method both in producing recommendations and in processing speed. © 2022 IEEE.

In indoor vertical farming systems, managing dynamic and complex environments poses significant challenges. Traditional control strategies often fall short in adapting to rapid changes in critical parameters such as nutrient levels, climate conditions, and plant health indicators. To address these challenges, this paper presents a novel approach for optimizing indoor vertical farming using Deep Deterministic Policy Gradient (DDPG), a reinforcement learning algorithm well-suited for environments with continuous action spaces. Our study focused on the control and monitoring of key parameters, including nutrient levels (pH and EC), climate conditions (temperature, humidity, light, and CO2 levels), and plant health indicators (biomass accumulation and leaf size structure). By defining a comprehensive state and action space, we simulated an indoor farming environment and trained the DDPG model to maximize crop yield and health. © 2024 IEEE.

Tamblang Dam is one of the dams, north of Bali Island, with a capacity of 7.6 million m3, and the downstream areas are in the form of agricultural land, citizen settlements, schools, offices, and other public facilities for approximately 10 km2. Considering such a downstream and its large capacity, the Tamblang Dam would have a significant damage impact if it is a failure. Therefore, it is necessary to analyze the failure of the Tamblang Dam. The study aims to analyze the areas affected by floods due to the dam’s failures and to measure the damage risk. The failures were simulated using HEC-RAS 5.0.7 with four scenarios, such as overtopping, upper-piping, middle-piping, and bottom-piping. The simulation result showed that the Tamblang Dam’s failure with the overtopping scenario had the worst impact as it has the highest velocity and discharge compared to the other scenarios. The overtopping scenario inundated 355 ha areas along the river. Six villages would become the victims, namely, Bengkala, Bila, Menyali, Jagaraga, Bungkulan, and Kubutambahan. Tamblang Dam failures’ danger level was figured out in this research according to the PenRis Hazard Classification of Dams in Indonesia. For this case, it is found that 2527 residents are at immediate risk of flooding caused by the failures. Therefore, following the Danger Classification from the Public Work and Housing Guidelines of Indonesia, it can be stated that the Tamblang Dam is a 4-class dam with an extremely high danger status level.

Technology advancements in energy harvesting have been sparked by increasing demand for renewable energy sources that are sustainable. This research work outlines the development and experiment of a prototype of piezoelectric voltage generation for energy harvesting from human footsteps. The study addresses the feasibility of generating electricity by converting mechanical energy from the vibrations generated by foot traffic in public areas such as stairs and entrance doors. The objectives of this study are to implement a sustainable and efficient method of generating electricity using piezoelectric materials, explore, and also optimize the mechanical design of the prototype to maximize the conversion of mechanical energy into electrical energy. The proposed system was developed on 2 different devices which are Tile A (25 parallel and 5 series sensor connections) and Tile B (20 parallel and 5 series sensor connections) and tested under different circumstances such as different tile placements, weights, and conditions which are 100, 200, and 300 steps to address the consistency on each predetermined parameter. Furthermore, the final system has the highest voltage generated up to 0.98 V from tile A and 2.54 V from tile B. This is due to the different approach of human footsteps when stepping on stairs and entrance door.

Total dissolved solids (TDS) consisting of inorganic salts and organic matter are pollutants to the aquatic and water systems for human use. This paper studied the effect of ceramic adsorbent composition on improving the quality of the produced water (PW) by decreasing TDS before entering reverse osmosis (RO). Manufacturing ceramic adsorbents use a mixture of spent catalysts of residues catalytic cracking (RCC) and natural clay in various compositions. Experiments were performed using the PW from one oil and gas company in South Sumatra, Indonesia. The initial characterization of produced water contains total dissolved solids of 14,556 mg/L. The flow rate of PW into the ceramic adsorbent column were varied from 6 to 8 L/min at a contact time of 15 to 120 min. The results showed that ceramic adsorbent A (diameter 10 mm and thickness 10 mm, 70% clay, and 30% RCC) reduced TDS by 74.58%. Adsorbent B (diameter of 20 mm and thickness of 10 mm, 70% RCC and 30% clay) lowers TDS by 56.68% at a flow rate of 6 L/min and a contact time of 60 min. Adsorbent C (diameter of 10 mm and thickness of 10 mm, 30% clay, and 70% RCC) reduced TDS by 59.40% at a flow rate of 6 L/min and a flow time of 60 min. Adsorbent D (diameter of 20 mm, thickness of 10 mm, 30% clay, and 70% RCC) lowers TDS by 54.38% at a flow rate of 6 L/ min and a contact time of 60 min. After being transferred into the adsorption column, their filtrates were sent into the Reverse Osmosis (RO) membrane. The final permeates of RO have TDS values between 1,720 mg/L to 3,930 mg/L that met water standards for oil and gas exploration wastewater in Indonesia. © 2023 The Authors. All rights reserved.
