Abstract

The relocation of the capital city of the Republic of Indonesia from Jakarta to the Nusantara Capital City (IKN) is a critical topic for the public, as it is designated as a strategic national project. However, the lack of public participation may generate community concerns regarding its potential impact. This research involved extracting public opinion from YouTube comments to identify the community’s desires, thereby providing policymakers with valuable information. Clustering the comments using the K-Means method successfully extracted public opinions from 27,063 comment data points. Among the key findings, a significant public concern is the potential for the construction project to be abandoned or stalled (“mangkrak”). Additionally, while the clustering results showed good cohesion, the cluster separation indicated a significant overlap in the data. This is further reflected by the average similarity score of 0.4234972.   Keywords – YouTube, Text Clustering, K-Means, Nusantara Capital City (IKN)

Abstract

Bridgestone Kalimantan Plantation, a rubber plantation company, currently manages employee payroll semi-manually using a Delphi-based desktop application and Microsoft Excel. This approach encounters several challenges, such as limited accessibility, data integrity issues, and time-consuming processes. To address these problems, this study aims to develop a web-based payroll information system. The primary objective of this research is to improve accessibility, streamline payroll management processes, and enhance data accuracy and security. The system is designed using the Laravel framework, chosen for its ease of use and security in implementing authentication and authorization, as well as its future integration capabilities. The results of the study indicate that the developed system functions as needed, providing a more efficient platform, reducing errors, and improving the user experience for employees involved in the payroll process. The implementation of this system is expected to enhance the overall operational efficiency of PT. Bridgestone Kalimantan Plantation.

Abstract

Penelitian ini bertujuan untuk mengembangkan aplikasi PERJADIN TABALONG sebagai solusi digitalisasi dokumen Surat Perintah Tugas, Surat Perjalanan Dinas, Laporan Perjalanan Dinas, serta Rincian Biaya pada Dinas Ketahanan Pangan, Perikanan, Tanaman Pangan, dan Hortikultura Tabalong. Permasalahan utama yang dihadapi instansi meliputi kesulitan rekapitulasi perjalanan dinas, keterbatasan pelacakan pegawai yang melaksanakan tugas luar, serta keterpisahan dokumen manual seperti surat tugas dan rincian biaya yang menyulitkan proses audit. Metode User Centered Design (UCD) digunakan untuk memastikan bahwa sistem yang dibangun sesuai kebutuhan pengguna melalui tahapan analisis konteks, perancangan, hingga evaluasi. Hasil implementasi menunjukkan bahwa seluruh fitur aplikasi berfungsi dengan baik, termasuk pengelolaan pegawai, pembuatan SPT dan SPD, penyusunan rincian biaya dan biaya riil, serta pencetakan dokumen dalam format PDF. Fitur dashboard dan rekapitulasi juga mampu menampilkan informasi perjalanan dinas secara real-time serta mendukung pencarian berdasarkan pegawai, lokasi, dan rentang waktu. Aplikasi ini terbukti meningkatkan efektivitas pengelolaan arsip perjalanan dinas, mengurangi kesalahan input, dan mempercepat proses administrasi. Dengan demikian, PERJADIN TABALONG berhasil memenuhi kebutuhan digitalisasi perjalanan dinas secara terpadu dan dapat dijadikan model implementasi pada instansi pemerintah lainnya.

Abstract

Pengabdian kepada masyarakat dengan tema Desain Label Kemasan Produk Jamur Tiram yang dilaksanakan di Desa Panggung Tanah Laut bertujuan untuk memberikan pengetahuan dasar kepada masyarakat desa mengenai desain label kemasan. Dalam hal ini kemasan produk olahan jamur tiram yang sedang mulai dibudidayakan oleh warga desa. Kegiatan pengabdian dilaksanakan melalui sosialisasi bersifat luring yang diikuti oleh anggota PKK desa. Sosialisasi diselenggarakan di Aula Desa Panggung pada tanggal 19 Oktober 2022. Kegiatan pengabdian masyarakat yang dilaksanakan telah memberikan peserta kegiatan pengetahuan mengenai desain label kemasan seperti analisis target pasar, pemilihan bahan label, trend desain kemasan produk, pemilihan tipografi, padanan warna, hak cipta elemen desain, serta kualitas cetak. Peserta sosialisasi mengikuti kegiatan dengan antusias melalui tanya jawab pada akhir sesi sosialisasi. Pelaksanaan kegiatan pengabdian masyarakat ini telah memberikan masyarakat pengetahuan dasar mengenai peran desain label terhadap produk yang mereka miliki. Ilmu pengetahuan yang didapat tidak hanya dapat digunakan untuk produk olahan jamur tiram, akan tetapi juga dapat diterapkan pada produk-produk lain yang mungkin kedepannya akan diproduksi juga oleh masyarakat Desa Panggung. Kata Kunci: Desain, label, produk, jamur tiram, kemasan.

Abstract

Large language models (LLMs) are attractive front-ends for academic information systems, yet a campus assistant must not invent grades, expose other students’ records, or drift into general chat paid from the institution’s budget. This study reports the design and empirical evaluation of an LLM assistant embedded in NeoSiakad.com, a multi-tenant academic information system delivered as software as a service to Indonesian higher-education institutions. Following a design science approach, the artefact combines four controls: a master control plane that provisions one gateway key with a USD ceiling per tenant, a fail-closed intent gate that classifies every message before the main model is called, read-only tool calling that executes canonical academic queries under the caller’s own permissions and tenancy, and retrieval-augmented generation (RAG) with mandatory citations and an abstain rule. Because RAG is not yet deployed, it was simulated on a 36-chunk academic guideline corpus. Evaluation used the public demo tenant, production telemetry, and seven language models accessed through the OpenRouter gateway. The intent gate reached 90.0 to 100 percent accuracy across models; the cheapest model let no disallowed message through at USD 0.04 per thousand calls. On the live tenant, 16 of 17 value-bearing turns reproduced the exact figures returned by the canonical resolvers, two cross-user probes were refused, and four disallowed prompts were rejected in 0.9 to 2.3 s without a main-model call. Retrieval reached Recall@3 of 1.00 for all five embedding models, and RAG raised fully correct answers from 0 to 14 percent (closed book) to 96 to 100 percent with 100 percent valid citations, while at most one of seven unanswerable questions was answered instead of declined. Moving chat turns to a queue worker cut the median turn latency from 40.9 s to 13.5 s on shared hosting. The results show that an LLM assistant can be made accurate, authorisation-bound, and cost-bounded on commodity infrastructure.
