Abstract

Milkfish is the largest freshwater fish commodity in Indonesia. Milkfish farming requires extra care and maintenance because these fish are sensitive to the environment, which can affect the growth and quality of fish. One important factor that affects milkfish growth is pond water quality, which can be measured through indicators such as temperature, oxygen levels, and water acidity. Today, water quality measurements are still traditionally done by coming directly to the pool, which requires additional time and effort. The purpose of this research is to develop e-chan as an Internet of Things-based innovation tool. The development of e-Chan is made using the SDLC (Software Development Lifecycle) method. The results showed the designed tool could be used to monitor pond water quality in real-time and transmit data to users through the app. Ikan bandeng merupakan komoditas ikan air tawar terbesar di Indonesia. Budidaya bandeng membutuhkan perawatan dan pemeliharaan yang ekstra karena ikan ini peka terhadap lingkungan yang dapat mempengaruhi pertumbuhan dan kualitas ikan. Satu faktor penting yang mempengaruhi pertumbuhan ikan bandeng adalah kualitas air tambak, yang dapat diukur melalui indikator seperti suhu, kadar oksigen, dan keasaman air. Saat ini, pengukuran kualitas air umumnya masih dilakukan secara tradisional dengan datang langsung ke kolam, yang membutuhkan waktu dan tenaga tambahan. Tujuan penelitian ini adalah mengembangkan e-chan sebagai alat inovasi berbasis Internet of Things. Pengembangan e-Chan dibuat dengan menggunakan metode SDLC (Software Development Lifecycle). Hasil penelitian menunjukkan alat yang dirancang dapat digunakan untuk memantau kualitas air tambak secara real-time dan mengirimkan data kepada pengguna melalui aplikasi.

Abstract

This study aims to measure the successful implementation of the Village Information System (SID) in Tabongo Village, Gorontalo Regency, using the DeLone and McLean model. This model measures the success of information systems based on six dimensions: system quality, information quality, service quality, usage, user satisfaction, and net benefits. Data were collected through a survey of 267 people (users) of SID in Tabongo Village. Data analysis was conducted using Partial Least Square Structural Equation Modeling (PLS-SEM) to test the relationship between the DeLone and McLean model variables. The results showed that system quality, information quality, and user satisfaction positively influence net benefits. Meanwhile, service quality and usage do not significantly affect net benefits. These findings suggest that efforts must be made to improve the quality of services and the use of SID to maximize the community's benefits. Socialization and training for SID users also need to be carried out to improve understanding and skills in using SID.

Abstract

Complexity measuring tools in computer science are deployed to measure and compare different characteristics of algorithms to find the best one to solve a particular problem or that suits a specific situation. Also,  this is used to measure the complexity of a software program without running the program itself. Given this, Halstead's complexity metrics are deployed to compare the efficiency of two external sorting methods: the Merge Sort and the Modified Merge Sort Algorithms. The methodology used in achieving this lies in extracting operators and operands from the C_sharp (C#) implemented program of the two algorithms. Six Halstead metrics are evaluated using these operators and operands as parameters. The results show that the modified merge sort algorithm is much more efficient than the conventional Merge sort as it has a lower Program Volume, Program Difficulty, and Program Effort even though the advantage of a higher Intelligence content goes to the merge sort algorithm.

Abstract

The issue of waste in Indonesia is still a severe problem that has not been resolved, and Indonesia is included among the top 10 countries as the most significant waste producer. These problems include people throwing their consumption waste in the open or even burning it, the lack of systematization of integrated waste management to provide information on waste collection and transportation, which causes environmental pollution and hurts public health, and the lack of effective monitoring and reporting in waste management. This hampers practical evaluation, planning, and decision-making efforts in waste handling and in conducting a waste retribution or payment system by the community. This research aims to develop a web-based integrated waste management information system to support sustainable development. The system development method used is the prototype model through the stages of communication, quick planning, modeling, quick design, prototype construction, deployment delivery, and feedback. The result of this research is the availability of data and information on waste management effectively and efficiently; this system can perform adequate data collection and documentation in registering all units affiliated with waste management to record waste payment transactions. In addition, this system can assist in managing and supervising the entire waste management process efficiently.

Abstract

Stemming in Ambonese posed a significant challenge due to its extensive lexicon, encompassing approximately 127,000 base words as recorded in the Kamus Besar Bahasa Indonesia (Indonesian Dictionary). This complexity arises from the task of extracting base words from those with affixes, necessitating the removal of various affixes such as prefixes, infixes, suffixes, and their combinations. This process greatly influences analytical outcomes. To address this linguistic complexity, several stemming algorithms were developed. These include Nazief Adriani, Enhanced Confix Stripping, Sastrawi, and Tala, each offering unique techniques to handle stemming complexities in Indonesian. The selection of the appropriate algorithm is crucial for ensuring the accuracy and reliability of the stemming process within the analytical framework. In conducted stemming research, there were variations in methods used. The most frequently used algorithm was Nazief Adriani, with 17 recorded cases, followed by Enhanced Confix Stripping with 12 cases. Sastrawi, although less frequent, was used in 4 cases, while Tala appeared in 1 case. This diversity reflects the available choices in selecting a fitting stemming method. However, this may relate to factors such as ongoing research projects, funding availability, or other external conditions affecting research production during that period. Consequently, stemming research remains an interesting and relevant topic, with the potential for continued growth and significant contributions to text processing and linguistic research in the future.
