Abstract

Sistem budidaya hidroponik tidak membutuhkan lahan atau halaman yang luas, lebih mudah dipelihara, dan tidak menyebabkan polusi dan dapat memperindah lingkungan dengan konsep penghijauan. Pelatihan hidroponik untuk memberdayakan masyarakat sangat penting untuk meningkatkan kesejahteraan masyarakat. Ini merupakan bagian dari program Pemerintah Desa Banjaranyar untuk meningkatkan kesejahteraan pangan masyarakat. Analisis situasi menunjukkan bahwa sebagian besar orang di Desa Banjaranyar bekerja dalam pertanian dan mengolah hasil pertanian. Masyarakat biasa menanam kacang tanah, singkong, dan ubi kayu, tetapi belum banyak dibudidayakan untuk tanaman sayuran. Beberapa jenis sayuran yang biasa dikomersilkan untuk tanaman hidroponik adalah caisim, pakcoy, selada, dan sejumlah jenis sayuran lainnya. Memanfaatkan sistem hidroponik untuk menanam tanaman di rumah dengan memanfatkan halaman atau perkarangan memiliki potensi yang cukup besar.

Abstract

In the current digital era, the application of technology has become a key element in improving efficiency and service quality, including in the operation of school cooperatives. Technology facilitates the management of the sale of school supplies in a more structured and efficient manner. School cooperatives, which serve as providers of students' needs, require a digital system to ensure that inventory and transactions can be managed optimally. This study aims to design and implement a web-based school supplies sales system at SDN 2 Berkoh's cooperative using the Waterfall method, to improve the cooperative's operational efficiency. This research utilizes the Waterfall method, covering the stages of requirement analysis, system design, implementation, and testing. System testing is conducted using the Blackbox approach to ensure that all features, such as inventory and transaction management, function according to the specifications. Additionally, system usability testing uses the System Usability Scale (SUS), involving 11 respondents to assess the ease of system use. The Blackbox testing results show that the system functions well in all main features, such as transaction recording and stock management. The SUS testing produced a score of 77, indicating that the system is quite easy to use. With this system in place, it is expected that the school cooperative can operate more efficiently, enabling students to meet their school needs more quickly and in an organized manner.

Abstract

Data analysis in research is an important thing to do after the research data is obtained. In designing a web application called Onti Measures, the files that have been executed have not been analyzed in more depth. Therefore, it is necessary to analyze the OWL (Web Ontology Language) files as test data for the Onti Measures application. This research aims to present a descriptive analysis of test data using three reasoners and compare their performance. The comparison of the three reasoners is seen based on running time, the performance of each reasoner, and the resulting inconsistency values. Those three reasoners are Hermit, JFact, and Pellet. In the Onti Measures application there are 10 inconsistency measures, namely drastic inconsistency measure, MI-inconsistency measure, MIc-inconsistency measure, Df-inconsistency measure, problematic inconsistency measure, incompatibility ratio inconsistency measure, MC-inconsistency measure, the nc-inconsistency measure, the mv-inconsistency measure, dan IDmcsinconsistency measure. The method used in this research is quantitative with a descriptive approach to analysis. The OWL fie input as test data is virus and disease ontology. The results of the descriptive analysis from this research include that 57.33% of the test data have an inconsistency value of 0 (consistent). Based on the performance of each reasoner in terms of processing ontologies, the three reasoners have almost the same capabilities. If it is seen from the resulting inconsistency values, the reasoner Pellet is better than the others. Meanwhile, based on the running time comparison, JFact is better than the other reasoners. The size of the ontology files does not affect the length of the running time.

Abstract

Inconsistency in an ontology can be a serious problem since it can mess up the information in the ontology. Ontology-based inconsistency measure gives inconsistency value of the whole base of the OWL ontology. It means the produced inconsistency value is used to evaluate its whole base. Based on this characteristic, there were 10 inconsistency measures created in the previous research and collected into one package of measures in an application program, namely Onti Measures. The application will not be useful if the measures do not work well. This problem leads to conduct evaluations. In this research, evaluations for the backend part of Onti Measures with the use of three kinds of OWL reasoners are done to know the performance of the application system with the comparison of each reasoner usage. The evaluations for the whole part of the application are not the scope of this research since they are only done for the backend part. Particularly, they are done with the black box method since the structure of the codes are not necessary to be known. They are evaluated with several OWL files as test cases and as the inputs of the backend program. The evaluation shows that the same inconsistent OWL file that is computed with a different type of inconsistency measure with any chosen reasoner may result in different inconsistency value. Other evaluations are provided. Overall, they show that Pellet is better than the two other reasoners and I_(D_f ) is more efficient than the other measures.

Abstract

Based on BPS data in 2022, 23.05% of the total population of Central Java do not have ICT skill (technologically clueless). It is possible that Purwokerto Kulon is included in this percentage. To reduce the number of people who are technologically clueless in Purwokerto Kulon, a basic ICT (Information and Communication Technology) counseling was held and attended by several participants from the youth and adult age groups. The counseling method used was training in the form of workshop, while the counseling material was about the introduction of computer hardware, basic computer operations, and basic internet operations and their benefits. Based on the results of the pre-test, it was found that only about 20% of the total participants had ICT skill. After participating in counseling, the post-test results showed information that 100% of them came to know and have the ICT skill.

Abstract

The success of software project management hinges on the ability to reliably forecast development effort. However, achieving precise estimates is notoriously difficult, primarily due to inherent project complexities and numerous uncertain variables. While various techniques exist, no single method has proven consistently reliable, leading to inaccurate scheduling and cost overruns. This study aims to develop a more accurate and robust estimation model by hybridizing a multi-criteria decision-making (MCDM) method for handling uncertainty with a machine learning algorithm for predictive modeling. The proposed approach integrates the Consistent Fuzzy Preference Relation (CFPR) method to derive consistent weights for cost drivers from expert judgments. These weights are then used as Effort Adjustment Factors (EAF) to preprocess the COCOMO and NASA datasets, which are subsequently modeled using the Least Squares Support Vector Machine (LSSVM). Evaluation of the hybrid CFPR-LSSVM model confirmed its enhanced predictive accuracy. For the COCOMO dataset, the model yielded an MMRE of 28.463% and an RMSE of 0.4705. Its performance on the NASA dataset was particularly remarkable, with results indicating an MMRE of 1.104% and an RMSE of 0.4593, demonstrating a level of precision that underscores the model's effectiveness. This research contributes a novel hybrid framework that effectively combines consistent fuzzy preference handling with powerful non-linear regression. By providing a more structured and robust methodology for managing uncertainty, this approach offers a substantial advancement in software effort estimation, delivering more reliable predictions for improved project planning.

Abstract

Global warming often causes the weather to become more unpredictable. Especially in Indonesia, currently the dry and rainy seasons often come unexpectedly. Unpredictable weather can also interfere with household chores, for example, drying clothes. An automatic clothesline control system is proposed as a solution to this problem. This research aims to build a prototype of a smart clothesline based on ESP8266 using the prototyping system development method and analyze its quality using the product testing method with product quality dimension attributes. The hardware used in the development includes Arduino Uno, NodeMCU ESP8266, rain sensor, infrared sensor, LDR sensor, and servo motor. Meanwhile, the software used is Blynk. The attributes assessed in the test include performance, durability, conformance to specifications, features, reliability, aesthetics, perceived quality, and serviceability. In other similar studies, the use of such product testing has never been done. The results of the study show that the smart clothesline prototype that was built has passed the product test with a product test value of 90.10.
