Abstract

Perkembangan fraktal yang sangat dinamis disebabkan oleh kegunaan dari fraktal sendiri yang bisa diterapkan ke banyak lintas bidang, diantaranya adalah biosains. Permasalahan dalam bidang biosains diantaranya adalah analisis pola curah hujan di suatu tempat yang fluktuasinya relatif tinggi dan cara mengidentifikasi seseorang menggunakan telapak tangan. Artikel ini mencoba memberikan gambaran terhadap penggunaan dimensi fraktal dalam bidang biosains. Metode yang digunakan antara lain metode eksponen hurst dan metode box counting.

Abstract

BSM Trans is a company engaged in car rental ranging from car rental services plus drivers, Off Key Car Rental, All In or Carter Package Car Rental, Tour and Travel Services, Airport Shuttle and Expedition Services both small and large scale. The purpose of this research is to increase customer retention and improve the design of the BSM Trans website using the User Centered Design (UCD) approach. The research method uses User Centered Design (UCD) in redesigning the BSM Trans website. After that, it was continued with the System Usability Scale (SUS) method to involve the use of questionnaires distributed through google forms by applying the SUS questionnaire to test the usability of a system. The results obtained are research before the SUS redesign that was obtained 38% where the grade scale was at F with poor indicators. But after redesigning the SUS value obtained increased dramatically by 84.75% which is on grade scale A with good indicators. This proves that the design improvements made bring an increase in the average SUS score by 46.75% This proves that testing with SUS in this study was successfully carried out and the new design design can be well received by users.

Abstract

This community service program revitalizes the Lungun Indah riverside attraction in Banyuwangi through a digital-tourism, community-based approach. The intervention integrates (i) physical enhancement—area cleaning, repainting, layout reorganization, and ornamental planting; (ii) safety enablement—provision of life jackets and an inflatable boat to support family-friendly river activities; and (iii) digital capacity building—creation of an official Instagram account, development of a tourism website with a virtual tour, and hands-on training for video promotion and website management involving Digital Business students. Methods followed sequential phases: problem analysis with local stakeholders (Bumdes and village officials), collaborative site improvement, digital content and platform development, training, and evaluation via a short Likert survey administered to Bumdes managers and village officers. Results indicate visible upgrades in cleanliness and aesthetics, improved visitor safety readiness, and stronger online visibility alongside emerging skills for independent content production and website upkeep. Survey feedback shows high acceptance and perceived relevance of the interventions, supporting the feasibility of sustained, locally managed promotion and operations. The program demonstrates that coupling basic physical readiness with targeted digital marketing and community capacity can effectively enhance destination appeal, strengthen governance at village level, and provide a scalable model for rural tourism revitalization.

Abstract

ABSTRAK Indonesia termasuk dalam negara ketiga dengan prevalensi tertinggi di Asia Tenggara. Salah satu yang masih menjadi kendala dalam pencegahan stuntingadalah lambatnya pemantauan tumbuh kembang anak, terutama di wilayah pedesaan. Proses pencatatan pertumbuhan balita di Posyandu masih bersifat manual, yaitu bidan mencatat hasil pengukuran pada kertas kemudian hasil rekapan pengukuran akan dimasukkan oleh operator ke Sistem PPGBM Kementerian Kesehatan. Hal tersebut mengakibatkan proses pendataan memakan waktu yang panjang, dan antrian panjang selalu terjadi pada setiap pengukuran di Posyandu. Untuk mengatasi masalah diatas, perlu dibangun sebuah timbangan digital yang dapat mengotomasi proses input data perkembangan balita. Timbangan tersebut menggunakan sensor RFID. Nantinya warga hanya perlu menempelkan kartu RFID yang telah dibagikan sebelumnya ke timbangan, kemudian naik ke atas timbangan. Secara otomatis hasil timbangan akan tersimpan sesuai identitas pemilik RFID.Hasil penimbangan kemudian dapat diekspor dalam bentuk excel sesuai format e-PPGBM. Hasil pengukuran menunjukkan bahwa penggunaan timbangan digital berbasis IoT dapat mempercepat waktu pengukuran dan mengurangi waktu tunggu balita. Hasil pengukuran juga dapat diunggah ke sistem e-PPGBM tanpa mengakibatkan error Kata Kunci: Timbangan Iot, Sistem Informasi Kesehatan, Status Gizi Anak  ABSTRACT Indonesia ranks among the third highest-prevalence countries in Southeast Asia. One of the persistent challenges in preventing stunting is the slow monitoring of child growth, particularly in rural areas. The process of recording the growth of toddlers in Posyandu (Integrated Health Service Posts) is still done manually, with midwives jotting down measurement results on paper, which are later entered into the Ministry of Health's PPGBM System by operators. This leads to a time-consuming data collection process, resulting in long queues during every measurement session at Posyandu. To address these issues, there is a need to develop a digital scale that can automate the input of child development data. This scale utilizes RFID sensors. In this system, residents only need to attach their previously distributed RFID cards to the scale and then step onto it. Automatically, the measurement results will be stored according to the owner's RFID identity. The weighing results can then be exported in an Excel format, complying with the e-PPGBM standard. The measurement results show that the use of IoT-based digital scales can speed up the measurement process and reduce waiting times for toddlers. Additionally, these measurement results can be uploaded to the e-PPGBM system without causing errors. Keywords: IoT Based Weight Scale, Healthcare Information System, Child Nutrition Status

Abstract

The digital economy presents new opportunities and challenges for micro, small, and medium enterprises (MSMEs). This study explores hidden patterns in social media data to strengthen MSMEs in the culinary, tourism, and fashion-textile sectors. Using a mixed-methods approach, quantitative data mining of leading brands’ social media was combined with qualitative validation through interviews with nine MSME representatives. Quantitative analysis revealed key engagement trends and content strategies, while qualitative insights confirmed their relevance and feasibility for SMEs. The integration of findings demonstrates that social media analytics can guide SMEs in enhancing digital presence, improving competitiveness, and adapting to shifting consumer behaviors. The study contributes practical recommendations for MSMEs while positioning social media as a strategic tool for sustainable growth in the digital era.
