Abstract

Sebuah website diperlukan dalam sebuah instansi, perusahaan, ataupun tempat pendidikan. Universitas Mulawarman memiliki website beralamatkan www.unmul.ac.id dan memiliki aplikasi Sistem Informasi Akademik (SIA). Oleh karena itu, tujuan penelitian ini adalah mengevaluasi kepuasan mahasiswa terhadap aplikasi SIA, mengetahui atribut yang perlu diperbaiki berdasarkan dimensi WebQual, dan memberikan usulan perbaikan dengan House of Quality (HOQ). Pengukuran tingkat kepuasan mahasiswa pada aplikasi SIA menggunakan metode WebQual. Hasil penelitian menunjukkan tingkat kepuasan mahasiswa terhadap aplikasi SIA adalah cukup puas dengan rata-rata kepuasan 3,030. Tingkat kepuasan mahasiswa terhadap dimensi usability adalah cukup puas dengan rata-rata kepuasan 3,160, terhadap dimensi information quality cukup puas dengan rata-rata kepuasan 3,124, dan terhadap dimensi interaction quality cukup puas dengan rata-rata kepuasan 2,806. Hasil dari Importance Performance Analysis menunjukkan atribut yang mempunyai tingkat kepuasan rendah dan tingkat kepentingan tinggi adalah ketepatan waktu aplikasi SIA dalam memberikan informasi sesuai kebutuhan pengguna dan tingkat relevansi aplikasi SIA terhadap informasi akademik berdasarkan IPA. Usulan perbaikan pada aplikasi SIA untuk mengatasi kedua atribut tersebut adalah memberi informasi tepat waktu sesuai kebutuhan mahasiswa seperti adanya deadline waktu antara dosen ke jurusan, jurusan ke fakultas dan menyediakan informasi yang relevan sesuai kebutuhan mahasiswa seperti jadwal kuliah, jadwal ujian, kapasitas kelas, serta adanya warning dialog untuk mengatasi kesalahan input mahasiswa jika persyaratan tidak memenuhi atau kesamaan jadwal kuliah.

Abstract

This study aims to determine and analyze the influence of the Work Environment and Work Motivation on the Performance of SD Alam Baiturrahman Bontang Teachers. The type of research used in this study is quantitative. The data analysis method used is multiple linear regression. The population in this study were SD Alam Baiturrahman Bontang Teachers, the number of samples in this study was 30 teachers. Based on the results of hypothesis testing in this study, the Work Environment variable does not affect the Performance of SD Alam Baiturrahman Bontang Teachers, while the Work Motivation variable affects the Performance of SD Alam Baiturrahman Bontang Teachers. Simultaneously or together, the Work Environment and Work Motivation variables affect the Performance of SD Alam Baiturrahman Bontang Teachers. The determination coefficient (R2) value is 0.406 or 40.6%. This shows that the work environment and work motivation are able to explain 40.6% of teacher performance. While the remaining 59.4% is influenced by other variables not examined in this study.

Abstract

This study was conducted to assess the service quality of UMKM Amplang Bontang Store by applying the Customer Satisfaction Index (CSI) and the Retail Service Quality Scale (RSQS). The results indicate that the overall service quality is relatively good, as reflected in a CSI score of 74%, signifying that customers are fairly satisfied with the store’s services. Among the dimensions, social interaction achieved the highest CSI score (83%), while the policy dimension recorded the lowest (63%). Further analysis using the RSQS method identified that the policy dimension has the most significant negative gap (-1.0). Specifically, attribute KB4 (-1.91) emerged as the lowest-performing attribute, making the policy dimension particularly KB4 the primary focus for service improvement.

Abstract

Kepuasan nasabah merupakan aspek krusial dalam industri asuransi karena sifat layanannya yang jangka panjang dan berbasis kepercayaan. PT XYZ menghadapi masalah keterlambatan dalam penyelesaian klaim nasabah, meskipun prosedur menetapkan batas maksimal 30 hari kerja. Penelitian ini bertujuan menganalisis kepuasan nasabah terhadap pelayanan klaim menggunakan metode Customer Satisfaction Index (CSI) dan Service Quality (SERVQUAL), serta mengidentifikasi faktor keterlambatan melalui analisis Five Whys. Metode pengumpulan data dilakukan dengan penyebaran kuesioner kepada 60 responden serta wawancara dengan pihak manajemen. Hasil SERVQUAL menunjukkan bahwa atribut “PT XYZ menjamin ketepatan waktu dalam penyelesaian klaim nasabah” memiliki kesenjangan tertinggi (-1,08), mengindikasikan prioritas perbaikan. Nilai CSI sebesar 79,55% menunjukkan bahwa pelanggan merasa puas, meskipun masih terdapat ruang untuk peningkatan. Analisis Five Whys mengungkapkan bahwa akar masalah keterlambatan adalah penundaan pembayaran beban operasional. Perusahaan disarankan menyediakan dana cadangan dan memprioritaskan pembayaran klaim saat kondisi keuangan terbatas. Implikasi praktis dari hasil ini membantu perusahaan mengalokasikan sumber daya secara tepat dan meningkatkan efektivitas mitigasi risiko. Arah studi lanjutan dapat difokuskan pada evaluasi efektivitas strategi mitigasi yang diusulkan serta penerapan metode HOR pada unit lain untuk pemetaan risiko yang lebih luas dan terstruktur.

Abstract

Distribution is a key activity in the supply chain as it is directly related to product delivery to customers. PT Sariguna Primatirta Tbk, the producer of Cleo bottled drinking water, distributes 19-liter gallons from its Samarinda depot using a single vehicle with a maximum capacity of 100 gallons. However, fluctuating demand often leads drivers to choose routes based on perceived shortest distance, which may cause inefficient fuel usage. This study applies the Vehicle Routing Problem approach using the Clarke & Wright Saving Heuristic and Sequential Insertion algorithms. The results show that the Sequential Insertion algorithm reduced the total distance to 294.70 km, achieving fuel savings of Rp57.400.00 (16.30%). In comparison, the Clarke & Wright Saving Heuristic reduced the distance to 320.10 km with fuel savings of Rp32.000.00 (9.09%).

Abstract

This research aims to optimize the distribution route of snack products for UMKM Srikandi Samarinda using the Vehicle Routing Problem (VRP) approach. The main issues are high travel distances, fuel costs, and delivery times due to the absence of route optimization. Two VRP solution methods are compared: Clarke and Wright Savings (CWS) and Cluster First Route Second (CFRS). The CWS method reduces travel distance by combining routes based on the highest distance savings between customer points, maximizing vehicle capacity. The CFRS method groups customer points into clusters using the Sweep algorithm based on proximity to the depot and determines the visit sequence within each cluster using the Nearest Neighbor method. Results show CFRS achieves better distribution efficiency. On the first route, CFRS traveled 94.1 km using 7 liters of fuel (Rp88,550), while CWS traveled 113.7 km using 9 liters (Rp113,850). On the second route, both methods covered about 75 km with similar fuel costs (Rp75,900), but CFRS was more consistent in savings, with the highest efficiency at 63.28%. With a total fuel cost saving of Rp140,939 compared to the initial condition, CFRS is recommended as the optimal solution, capable of reducing distance, operational costs, and improving delivery effectiveness.
