Abstract

Gerardus Mayella Kalembu Weri High School is a school that operates in the field of educational institutions which currently still has problems with the process of admitting new students requiring quite a long time in filling out paper forms and student data still using the main book as a medium for storing student data. Then the committee will input or copy student data on the computer, which is a problem regarding new student registration which is still manual, which of course keeps the committee busy in terms of new student registration. And the data could be lost because it is still in the form of sheets of paper. System This can be more efficient in terms of costs, energy and time, so that it is effective in achieving goals. In accessing the current system, we sometimes experience obstacles in implementing information, such as accepting new students. For this reason, a special information system is needed to overcome this problem, namely an online registration information system. This system was developed using web engineering methods. The method is used to create a web-based application system using engineering science, management principles and a systematic approach so that high quality web systems and applications can be obtained.

Abstract

The primary objective of this study is to examine the impact of the green economy and local wisdom-based entrepreneurial innovation on the revenue of weaving MSMEs in Southwest Sumba Regency. Employing a quantitative approach with an explanatory research design, this study observes local handwoven fabric artisans. From the existing population, a sample of 45 business operators was selected using a purposive sampling technique. Primary data were gathered via Likert-scale questionnaires and subsequently analyzed using multiple linear regression. Field findings demonstrate that implementing a green economy—through eco-friendly raw materials, resource efficiency, waste reduction, and sustainable product creation—positively boosts income. Concurrently, innovation rooted in local heritage drives revenue growth by exploring traditional motifs, preserving authentic weaving techniques, embedding cultural values, utilizing local narratives, and strengthening product identity. Simultaneously, both aspects play a crucial role in enhancing competitiveness, profitability, and business sustainability. These final outcomes prove that accelerating weaving MSMEs relies not merely on product quality, but on strategic vision that merges environmental preservation with the power of local cultural roots.

Abstract

Perkembangan teknologi informasi menghadirkan peluang strategis untuk memperkuat tata kelola serta promosi pariwisata berbasis kearifan lokal secara lebih efektif dan terintegrasi. Desa Wendewa Barat memiliki potensi wisata adat yang unik, seperti proses pembangunan rumah adat dan berbagai aktivitas budaya tradisional yang sarat nilai sosial, historis, dan edukatif. Namun demikian, potensi tersebut belum didukung oleh platform digital yang mampu menyajikan informasi secara luas, terstruktur, dan mudah diakses oleh masyarakat maupun wisatawan. Kondisi ini menyebabkan rendahnya literasi publik terhadap daya tarik wisata desa serta belum optimalnya kontribusi sektor pariwisata terhadap peningkatan ekonomi lokal. Penelitian ini bertujuan untuk merancang dan membangun sistem informasi pariwisata desa berbasis web menggunakan framework CodeIgniter 4 (CI 4), serta menganalisis efektivitasnya dalam meningkatkan aksesibilitas informasi wisata adat agar menjadi salah satu promosi wisata berbasis digital. Pengembangan sistem menerapkan model Waterfall melalui tahapan analisis kebutuhan, perancangan sistem, implementasi, dan pengujian. Hasil penelitian menunjukkan bahwa sistem mampu menyajikan informasi secara sistematis, informatif, interaktif, dan mendukung promosi digital berkelanjutan.

Abstract

Manajemen surat merupakan salah satu kegiatan administrasi yang memiliki peran penting dalam mendukung kelancaran pelayanan dan tata kelola pemerintahan desa. Pengelolaan surat masuk dan surat keluar yang dilakukan secara sistematis akan mempermudah proses pencatatan, penyimpanan, pencarian, serta pelaporan dokumen administrasi. Namun, pada Kantor Desa Laga Lete, proses pengelolaan surat masih dilakukan secara manual menggunakan buku agenda, sehingga sering menimbulkan berbagai kendala, seperti lambatnya proses pencatatan, kesulitan dalam menemukan kembali arsip, tingginya risiko kehilangan dokumen, serta kurang efektifnya penyusunan laporan administrasi. Kondisi tersebut menunjukkan perlunya penerapan sistem informasi yang mampu mendukung pengelolaan surat secara lebih efektif dan efisien. Penelitian ini bertujuan untuk merancang dan membangun Sistem Informasi Manajemen Surat berbasis framework CodeIgniter sebagai solusi dalam meningkatkan kualitas pengelolaan administrasi persuratan di Kantor Desa Laga Lete. Metode penelitian yang digunakan meliputi analisis kebutuhan sistem, perancangan sistem menggunakan Unified Modeling Language (UML), implementasi aplikasi berbasis web, serta pengujian fungsional menggunakan metode Black Box Testing untuk memastikan seluruh fitur berjalan sesuai dengan kebutuhan pengguna. Sistem yang dikembangkan menyediakan fitur pengelolaan surat masuk, surat keluar, pencarian arsip berdasarkan berbagai kriteria, serta pembuatan laporan secara otomatis. Hasil penelitian menunjukkan bahwa sistem yang dibangun mampu meningkatkan efisiensi proses administrasi, mempercepat pencarian dokumen, meminimalkan kesalahan pencatatan, serta menghasilkan arsip dan laporan yang lebih akurat, terstruktur, dan mudah diakses. Dengan demikian, sistem informasi ini dapat mendukung peningkatan kualitas pelayanan administrasi dan efektivitas pengelolaan surat di Kantor Desa Laga Lete.

Abstract

Expert systems are one of the fields of artificial intelligence (AI) that seeks to adopt human knowledge into computers, so that computers can solve problems as experts usually do. One of the problems handled by expert systems is diagnosis in the health sector, such as to diagnose early suspicions of human digestive diseases commonly known as digestive disorders. The expert system in this study was created in the form of a Web-based application. The application of an expert system with the certainty factor method is used to diagnose diseases in the human digestive system. Digestive diseases in this application are limited to diarrhea, gastritis, dysentery, gastric tumors (benign tumors of the stomach), and appendicitis (appendix). The application of an expert system for digestive diseases in humans contains information on diseases, symptoms, and follow-up treatment. This application can be used as an alternative media for diagnosing digestive diseases, and can help users predict the disease they are suffering from based on the symptoms experienced by the user. The expert system created using the certainty factor method, which means this method provides information related to the disease into a possibility, namely happening and not happening and not knowing. The system design used to illustrate the creation of an expert system consists of context diagrams and data flow diagrams and ERD (Entity Relationship Diagram)

Abstract

This study develops a web-based digital marketing platform for tourism-sector micro, small, and medium enterprises (MSMEs) in Rua Village to improve access to business information, product promotion, ordering, and transaction management. The research applies a software engineering approach through system analysis, system design, Agile Scrum development, and system testing. Data were collected through documentation, field observation, and interviews with tourism and MSME stakeholders. The resulting platform provides a public page for information and promotion, buyer registration and product purchasing, an MSME-owner dashboard for managing business information, products, orders, and reports, and an administrative dashboard for managing users, MSMEs, categories, products, transactions, payments, and public content. The system was developed through four Scrum sprints using Laravel, HTML5, Tailwind CSS, Vue.js, and MySQL. Functional evaluation using Black Box Testing covered 15 scenarios and achieved a 100% success rate. User experience evaluation used the System Usability Scale (SUS) with 30 respondents comprising MSME actors, tourism managers, and prospective tourists; the manuscript does not report a numerical SUS score because individual questionnaire responses were not included. The platform provides an integrated digital channel to support the promotion and transaction of local MSME products in Rua Village.

Abstract

Penentuan prioritas pembangunan desa merupakan proses strategis yang memerlukan pertimbangan kebutuhan masyarakat, urgensi, manfaat, biaya, pemerataan, dan kesiapan pelaksanaan. Ketika usulan pembangunan memiliki karakteristik berbeda dan anggaran terbatas, proses penentuan urutan prioritas membutuhkan kriteria yang eksplisit serta dokumentasi yang dapat ditelusuri. Penelitian ini menyusun rancangan sistem pendukung keputusan (SPK) berbasis web dengan metode Multi-Objective Optimization on the Basis of Ratio Analysis (MOORA) untuk membantu Pemerintah Desa Ramadana mengevaluasi usulan pembangunan secara terstruktur. Tahapan yang dirancang meliputi identifikasi masalah, penetapan alternatif, perumusan kriteria, pembobotan, normalisasi matriks keputusan, perhitungan nilai optimasi, pemeringkatan, dan rancangan pengujian sistem. Kriteria usulan terdiri atas urgensi kebutuhan, jumlah penerima manfaat, dampak sosial-ekonomi, pemerataan, kesiapan teknis, dan estimasi biaya sebagai kriteria cost. Untuk menjelaskan prosedur hitung, naskah menyertakan data sintetis yang secara tegas hanya merupakan simulasi dan bukan hasil survei Desa Ramadana. Dengan demikian, peringkat contoh tidak dapat dianggap sebagai rekomendasi aktual sebelum seluruh alternatif, bobot, dan nilai diverifikasi melalui data lapangan. MOORA diposisikan sebagai alat bantu analitis yang melengkapi musyawarah desa, bukan menggantikan keputusan partisipatif atau pemeriksaan legal, teknis, lingkungan, dan anggaran. Rancangan ini dapat direplikasi setelah data primer resmi tersedia. Penerapan rancangan tersebut diharapkan mampu meningkatkan transparansi, akuntabilitas, dan konsistensi dalam proses evaluasi serta penentuan prioritas pembangunan desa.
