This study aims to design, implement, and test a prototype that automates three functions, namely watering, fertilizing, and pest control based on Arduino Uno with the ability to directly monitor soil moisture and pH. This system is equipped with four main types of sensors. Soil condition monitoring involves an FC-28 soil moisture sensor and a soil pH sensor, water level measurement involves an HC-SR04 ultrasonic sensor, and pest detection in the plant area involves a RIP sensor. All data obtained from these sensors is then processed by the Arduino Uno microcontroller to automatically activate actuators such as water pumps, liquid fertilizer pumps, buzzers, and DC motors according to soil conditions and plant needs. Prototype testing was conducted on simulated land with various scenarios of moisture, soil pH, and pest activity. The test results revealed that the system was proven to be able to significantly optimize water and fertilizer utilization, as well as reduce pest disturbances that could potentially damage plants.  In addition, this system also displays the operational status directly through an LCD screen, making it easy for users to monitor. The advantage of this system is its multi-function integration in a single device that is cost-effective and easy to operate. In the future, the functionality of this system can be improved through integration with Internet of Things (IoT) technology, enabling remote monitoring and control with greater efficiency. More broadly, this study is expected to support increased production and sustainable agricultural practices in Indonesia.

The analysis methods used in this study include a case study on the use of closed-loop recycling and an evaluation of biopolymer performance across various industries, both of which are important components in the transformation of the manufacturing industry toward a circular economy. The research findings indicate that recycled materials can reduce carbon emissions by thirty to fifty percent and save production costs by fifteen to twenty-five percent. Artificial intelligence-based sorting technology improves sorting efficiency to 95 percent, and closed-loop recycling maintains the mechanical properties of materials up to 90 percent after four cycles. The degradation rate of biopolymers like PLA and PHA reaches 60-80% within six months, although production costs are still 2-3 times higher. The integrated approach increases resource efficiency by 45% and reduces waste by 60%. To achieve successful implementation, Extended Producer Responsibility (EPR) policies, strategic infrastructure investments, and collaboration from various parties thru the triple helix model must work together.

Production planning and inventory control are critical aspects of operations management, as they directly influence cost efficiency, resource utilization, and the continuity of the production process. Ineffective planning and inventory decisions may lead to excessive costs, production delays, or imbalances between supply and demand. The complexity of these problems, which often involve multi-period horizons and multi-stage decision-making processes, has encouraged the application of quantitative optimization methods, one of which is dynamic programming. This study aims to analyze and synthesize the application of dynamic programming in production planning and inventory control through a Systematic Literature Review (SLR) approach. The SLR process was conducted by systematically identifying, selecting, and analyzing 15 relevant national journal articles published between 2015 and 2024 and obtained from various recognized scientific databases. The reviewed literature indicates that dynamic programming is effective in supporting optimal decision-making by determining appropriate production quantities and inventory levels, minimizing total production and holding costs, and managing fluctuating demand conditions. In addition, this method helps reduce the risks associated with overstock and stockouts by considering sequential decision structures. However, the findings also reveal several limitations of dynamic programming, including high computational complexity, strong dependence on deterministic data assumptions, and limited flexibility in handling high levels of uncertainty. These constraints suggest the need for further methodological development or integration with other approaches to enhance practical applicability.

Pricing is a critical factor determining the success of small and medium-sized enterprises (SMEs) in the market. This study investigates the pricing strategy implemented by Kebab Ajo Lubeg, a culinary SME located near Universitas Putra Indonesia YPTK Padang. The research aims to analyze how pricing methods are applied, the factors considered in price determination, and their influence on consumer purchasing decisions and business strategy. A qualitative descriptive approach was employed, with data collected through semi-structured interviews with the owner and employees, direct observation, and documentation of product offerings and pricing. Findings indicate that Kebab Ajo applies a combination of cost-based pricing, competition-based pricing, and product-based price variation to balance production costs, consumer purchasing power, and market competition. The pricing strategy significantly affects consumer satisfaction, repeat purchases, perceived value, brand image, and business competitiveness. This study provides practical insights for other SMEs in setting appropriate prices while maintaining customer loyalty and profitability, and it contributes to the academic discourse on marketing management and pricing strategies in the culinary sector.

Strengthening the family economy through the development of productive household-based businesses is an important strategy in supporting sustainable rural community development.

This study aims to analyze the profitability and feasibility of sheep farming using intensive and semi-intensive rearing sistems in Suka Raya Village, Pancur Batu Sub-district. The research employed a survey method with purposive sampling, involving 16 farmers (8 intensive and 8 semi-intensive), each rearing more than 15 sheep and operating for at least 3 years. Data were collected through questionnaire interviews and field observations, then analyzed descriptively to calculate production costs, revenue, income, R/C ratio, and Break Even Point (BEP). Results showed that the average total production cost for the intensive sistem was Rp 52,429,313, higher than the semi-intensive sistem at Rp 39,664,375. The average revenue for the intensive sistem was Rp 69,150,000, while the semi-intensive sistem was Rp 63,712,500. The average income for intensive farmers was Rp 16,720,688, compared to Rp 24,048,125 for semi-intensive farmers. The average R/C ratio for the intensive sistem was 1 (near break-even), while the semi-intensive sistem was 2 (more efficient and profitable). BEP analysis indicated higher sales for the intensive sistem (Rp 844,022/sheep/period) compared to the semi-intensive sistem (Rp 691,052/sheep/period), with a larger production BEP for the intensive sistem (44 sheep) than the semi-intensive sistem (33 sheep). The semi-intensive sistem is recommended for farmers with limited capital and small to medium-scale operations due to lower costs and higher profit margins, while the intensive sistem is more suitable for large-scale operations with adequate capital, feed management, and health care.

Business ventures are activities carried out by individuals or organizations involving the production, sale, purchase, or exchange of goods and services, with the aim of generating profit. A basic necessities store (commonly known as a “sembako” store in Indonesia) sells daily staple needs, especially the nine essential commodities (sembako), which include items such as rice, sugar, cooking oil, eggs, salt, and other key food ingredients. UD. Putri 2, located in Dusun 1A, Sumber Harapan Village (21261), Tinggi Raja Subdistrict, Asahan Regency, was established in 2018 and has since become an essential part of the local community. This has required UD. Putri 2 to constantly monitor their stock inventory. However, the company still faces inefficiencies in managing sales data processing, which often leads to inventory shortages. When the supply of goods is insufficient to meet customer demand, customers may turn to other stores. If this occurs repeatedly, the store risks losing profit due to the unavailability of goods. Supply Chain Management (SCM) refers to the integrated processes and production activities starting from the acquisition of raw materials from suppliers, the value-adding processes that turn raw materials into finished products, the inventory storage process, and the distribution of finished goods to retailers and consumers. The implementation of SCM can optimize inventory management of staple goods, minimize inventory costs, and improve supply chain efficiency at UD. Putri 2.

This study aims to determine the cost of production for Sa'dan woven fabric using two cost calculation methods, namely full costing and variable costing. These methods are applied to analyze the cost differences involved in the production process. Data were collected through observation and direct interviews with the weavers. Based on the research findings, the cost of production per sheet of woven fabric using the full costing method is Rp 316,800, which includes the costs of raw materials, labor, and production overheads. In contrast, the calculation using the variable costing method results in a lower production cost, amounting to Rp 314,690. Additionally, the uncertainty in the production quantity also affects the cost incurred. The higher the production quantity, the greater the cost incurred, which impacts the setting of selling prices and the desired profit by the weaver. Therefore, it is important for the weavers to consider efficiency in production planning in order to optimize costs and maximize profits. By understanding the differences between these two methods, the weavers are expected to make more accurate pricing decisions based on the current production conditions, ensuring better business sustainability.  

In the era of globalization and digital transformation, organizations strive to maintain competitiveness through optimizing internal factors such as work culture, business process engineering (BPR), and decision support systems (DSS). This qualitative research based on a Systematic Literature Review (SLR) analyzes the relationship between these three using the Denison Organizational Culture Model, Hammer & Champy BPR, and the Resource-Based View (RBV). It finds that work culture mediates the implementation of BPR and DSS to increase efficiency by 30-50%, employee productivity, and sustainable competitive advantage. Case studies such as the Toyota Production System (TPS) confirm this synergy, resulting in reduced costs, cycle times, and improved service quality. This research also emphasizes the importance of a strong work culture in supporting the implementation of new technologies and methodologies, which in turn strengthens the company's market position. Thus, organizations that are able to integrate these three elements will be better prepared to face the challenges of globalization and dynamic changes in their industry, creating a sustainable advantage and being able to survive in a highly competitive market.

The informal institution of mutual cooperation (gotong royong) in the rice farming community in Bhera Village, Mego District, Sikka Regency, remains the main foundation of social solidarity and the sustainability of agricultural activities even though modernization and the use of labor have begun to shift traditional values. A qualitative approach with a case study method was used to explore the role, form, and meaning of mutual cooperation in agricultural practices. Data were collected through in-depth interviews, participant observation, and documentation studies of rice farmers who are active in mutual cooperation activities. Data analysis was carried out through reduction, presentation, and drawing conclusions using triangulation techniques to ensure the validity of the findings. The results show that mutual cooperation is manifested in every stage of farming, from uprooting seedlings, planting (planting), clearing weeds, to harvesting, which is carried out voluntarily and in turns through the Irutan Tradition system. This institution functions as a collective work mechanism that reduces production costs, overcomes labor shortages, and strengthens social ties between farmers. Beyond its economic function, mutual cooperation has profound social and cultural significance as a symbol of brotherhood, togetherness, and collective responsibility in maintaining the sustainability of local wisdom and the resilience of farming communities amidst social and technological change.

Soil contamination by hydrocarbons, pesticides, heavy metals, and complex pollutants is rapidly increasing and degrading essential ecosystem functions. Physical or chemical treatments offer faster results, yet they are often costly, energy-intensive, and risk disrupting soil biological integrity without fully eliminating pollution sources. Microorganism-based bioremediation provides a more sustainable alternative by utilizing microbial metabolism to degrade or immobilize pollutants into less toxic and less mobile forms. This article presents a structured literature review on the roles and applications of microorganisms for bioremediation of contaminated soils, covering comparisons between single isolates and microbial consortia, dominant biological mechanisms, and ecological challenges in field application. A Systematic Literature Review approach was applied, using narrative synthesis and thematic clustering of national and international journals published between 2020 and 2025. The review indicates that single microbial isolates are commonly selected for specific pollutant targets, whereas microbial consortia are preferred for mixed or persistent contaminants due to metabolic synergy that enhances microbial adaptability and stepwise pollutant breakdown in highly polluted soils. Adaptive mechanisms such as EPS production and biofilm formation contribute to microbial resilience under stress and help retain contaminants within the soil matrix. Key challenges identified include inoculum stability under extreme conditions and limited microbial access to pollutants trapped in micro-soil pores. The findings highlight that microbial selection strategies must be tailored to pollutant characteristics and soil environmental conditions, while also emphasizing the potential of biofilm-based systems and organic carriers to support broader field implementation of microbial bioremediation.

In Indonesia, micro, small, and medium enterprises (MSMEs) have long been recognized as a very important business sector due to their various real roles in the economy. However, MSMEs often face many obstacles in running their businesses. More incentive support from various parties, especially the government, is needed for the development of MSMEs. In order to overcome the problems faced by MSMEs and support their sustainability, a KKU (Business Field Study) activity was carried out by Group 15 at the KKU-11 of the Institute of Technology and Business (ITB) Adias Pemalang at the MSME “Ev_Kids Product.”After conducting an observation phase, several problems faced by the SME were identified, including the lack of social media for marketing, failure to calculate the Cost of Goods Sold (COGS) and maintain simple accounting records, absence of a business logo, banners, promotional image designs, organizational structure, business profile, product catalog, stamps, receipt books, and product attributes. Additionally, the SME had never produced a production video or promotional video.After conducting the observation phase, KKU actors formulated several business development assistance programs, namely creating social media accounts, calculating the Cost of Goods Sold (COGS), creating simple bookkeeping, creating a business logo, banners, promotional image designs, organizational structure, business profile, product catalog, stamps, note books, and product attributes in the form of hangtags. They also created production videos and promotional videos.

The problem faced is the decline in the performance of a 650 liter/minute centrifugal pump due to wear on components, especially the impeller, rolling bearings, and mechanical seals in supplying process water and clean water in industrial production systems.
