<![CDATA[Welding is an important process in manufacturing work to produce strong and durable joints. In the welding process, there are various parameters that are considered and used, especially in the FCAW welding process. In this study, several types of FCAW welding machine parameters used are ampere, voltage, and interval time of welding. The purpose of this study is to obtain the best welding quality results by combining these parameters by finding a comparison of the three parameters to minimize one of the welding defects, namely deformation. The method used is using DOE. This method allows to identify the parameters that most affect the quality of the weld and determine the optimal settings for each parameter. From the results of data processing and analysis, it was found that the voltage parameter was the most influential on deformation. The combination of levels in the predetermined parameters is ampere at level 1 with a number of 150 A, voltage at level 1 with a number of 22 V, and interval time at 10 minutes. The experimental data model has been tested with regression analysis to obtain an R-squared of 79.43%, and the residual plot analysis follows a straight line, so that the model is normally distributed and the statistical test results are significant, meaning that the observation data represents real data.]]>

<![CDATA[Coconut (Cocos Nucifera L) is a versatile plant or has high economic value. All parts of the coconut tree can be used for human benefit, so this tree is often referred to as the tree of life. Coconut fiber can be used as a product that has high value and can increase farmers' income. It is processed to produce products from coconut fiber that can increase profits and maintain environmental sustainability. Processing of coconut fruit, especially its derivative products, still has considerable opportunities. The coconut fruit processing industry in general is still focused on processing fruit flesh as the main product, while industries that process by-products such as water, coir, and coconut shells are still processed traditionally. This coconut fiber can be developed into a variety of products. Waste from ice sellers is one of the coconut wastes that can be used to increase profits and preserve the environment. The research process was carried out using a case study of the ice business with Pak Mamat which was observed through a process of observation and interviews, the processing of the waste contained in this process was carried out by utilizing it into handicraft items, namely plant pots made from coconut fiber waste]]>

<![CDATA[The golden age in toddlers significantly influenced their growth, so it was essential to know the adequacy of nutritional needs in children. One way to assess the adequacy of nutrition in children was by measuring height and weight. However, height and weight variables in toddlers were highly representative. Until now, both measurement processes have been done manually, and the results have been recorded in a logbook. Thus increasing the risk of errors due to human involvement in data recording. This research aimed to design a prototype of an automatic device capable of measuring height and weight automatically. This prototype was based on Arduino Uno technology using ultrasonic sensors along with weight sensors, such as load cells and HX711. Furthermore, the data generated were integrated with the web for more effective storage. From the designed device, a pretty good level of measurement accuracy was obtained. The test results showed that the height-measuring device using ultrasonic sensors demonstrated an accuracy level of 97.99%. Meanwhile, the weight-measuring device using a load cell sensor showed an accuracy level of 82.53%. After testing together with the Melati Putih Posyandu Cadres, a good response was obtained. The satisfaction level measurement using the System Usability Scale method yielded a score of 80.75 points. It can be concluded that the built system was in the acceptable category. ]]>

<![CDATA[In this research, a hydrophobic layer has been successfully created on the surface of a steel plate using natural mineral silica modified with MTMS (Methyltrimethoxysilane) precursor. The synthesis process begins with the process of purifying silica sand, titration and calcination to obtain mineral silica in the cristobalite phase. This research used three variations of calcination holding time for silica minerals. Variations in the calcination holding time for the mineral silica used were 8 hours, 12 hours and 16 hours using the same temperature, namely 950°C. Each variation of silica mineral that has been synthesized is then modified with MTMS precursors. The names of the modified silica samples are modified MTMS/SiO2 V1, modified MTMS/SiO2 V2, and modified MTMS/SiO2 V3 with a mineral silica calcination holding time of 8 hours, 12 hours, and 16 hours respectively. The synthesized silica powder is then mixed with steel ship paint and applied to the surface of the steel plate as a topcoat layer. The coating method used is the brush coating method. Increasing the concentration of silica powder and the calcination holding time of silica minerals affect the roughness and hierarchical structure of the steel plate surface. Surface roughness and hierarchical structure are important indicators of the formation of a hydrophobic surface. Roughness on the surface of a steel plate can be identified by performing AFM (Atomic Force Microscope) characterization. The AFM characterization results show that the highest roughness is found in the MTMS/SiO2 modified V3 sample. Hydrophobicity on the surface of the steel plate can be identified from the WCA (Water Contact Angle) test. WCA testing is carried out using two different types of liquid, namely fresh water and sea water. The highest water contact angle produced in this study was 128° using fresh water and 134° using sea water.]]>

<![CDATA[The study aims to assess the influence of the blue economy and per capita income on Madura Island's economic growth. The analysis using panel data regression models revealed that the blue economy variable has a significant negative influence, while the per capita income variable has a significant positive influence on economic growth. These findings suggest that although the Blue Economy concept has enormous potential, its implementation in Madura still faces challenges that require immediate handling to ensure a positive impact on economic growth. On the contrary, increased per capita income clearly contributes to economic growth, stressing the need for policies that focus on raising wages, skills, and employment opportunities. The findings provide important guidance for policymakers to refine sustainable development strategies in Madura, with an emphasis on optimising the Blue Economy and improving public well-being.]]>

<![CDATA[This research aims to develop a circular economy-based business process model for the traditional weaving industry in Nusa Tenggara Timur (NTT), Indonesia. The study addresses the problem of waste generation and resource inefficiency in the existing linear production process, which relies heavily on synthetic dyes and lacks systematic reuse or recycling practices. By applying the Business Process Model and Notation (BPMN) and the Circular Business Model Canvas (CBMC), a redesigned process integrates waste recovery, reuse, and upcycling. Simulation results indicate that introducing natural dyeing, product diversification from leftover materials, and reverse logistics significantly reduce environmental impact while increasing revenue by 15–20%. This model demonstrates the feasibility of adopting circular principles in small-scale traditional industries, providing environmental benefits and economic resilience. The findings contribute to sustainable business practices and offer a replicable framework for similar sectors.]]>

<![CDATA[Salt is a mineral that humans need. Indonesia has abundant biodiversity, including 20,089 hectares of salt-productive land. However, despite this great potential, Indonesia still has to import salt to meet the national needs that continue to increase yearly. The increase in salt consumption is influenced by population growth. Salt is used in two main categories: consumption and industry. An efficient salt production process will produce higher-quality salt. However, currently, many salt farmers are still using manual methods that are less efficient and time-consuming, and also the water used as raw material has not been filtered. Microfiltration is carried out to reduce water turbidity, which aims to filter microscopic objects so that the water used in the salt crystallization process becomes cleaner. Salt production is carried out by the stage of the microfiltration process automatically based on the level of water turbidity, and the height of the salt evaporation container is regulated by the rule-based method as a control on the servo. By conducting this study, the percentage of ultrasonic sensor error reached 22.21%, and the higher the Analog to Digital Converter value was obtained, the lower the turbidity level (NTU). Using the rule-based method allows the condition of the servo motion to be determined with the value obtained through the sensor.]]>

<![CDATA[In the context of Islam, humans have the duty to educate themselves, purify their souls, and control their desires. Worship performed with sincerity and pure faith is considered a blessing. One example of worship in Islam is performing the Hajj pilgrimage, which is one of the five pillars of Islam, along with the declaration of faith (shahada), prayer (salat), almsgiving (zakat), and fasting (sawm). Hajj requires self-control, dedication, and sacrifice, including financial resources (Noor, 2018). However, the cost of the Hajj pilgrimage, proposed by the Ministry of Religious Affairs (Kemenag), is set to increase by almost 100% from the previous year, reaching IDR 69 million per person in 2023, eliciting various responses from the public. Some responses are constructive and positive, while others oppose the increase. Sentiment analysis is the method used to analyze public reactions to this change. Data for sentiment analysis was gathered from Twitter, with tweets processed using the Tf-Idf and Tf-Rf word weighting methods. The K-Nearest Neighbors (KNN) algorithm was then employed to assess the accuracy and effectiveness of these methods. The study findings revealed that the Tf-Idf word weighting method outperformed Tf-Rf in categorizing public sentiment regarding the cost of the Hajj pilgrimage. Tf-Idf achieved 84% accuracy, 81% precision, and 79% recall, while Tf-Rf achieved 79% accuracy, 75% precision, and 77% recall. Tf-Idf is considered superior in this sentiment analysis, providing precise predictions while effectively capturing important sentiments. Therefore, this method is deemed a reliable choice for accurate sentiment analysis]]>
