Abstract

The limitations of conventional static and inflexible Customer Relationship Management (CRM) systems have resulted in significant challenges in adapting to the specific needs of various types of businesses, with PerFormance being restricted in terms of flexibility to adapt to market changes. After implementing a CRM system with a static Workflow, PT Rintis Sejahtera recorded significant improvements, such as a 35% increase in customer request handling speed and a 28% increase in customer satisfaction. This research aims to develop a web-based CRM system with dynamic Workflows that can enhance operational Efficiency and effectiveness, allowing it to adapt to future changes. The study focuses on implementing web technologies to design and develop a CRM system capable of adjusting Workflows according to the specific needs of the user company. The research methodology used in this study includes the PIECES framework and the Waterfall model.

The results of the study show that the web-based CRM system with dynamic Workflows successfully improved operational Efficiency and effectiveness by 50% in customer request handling speed and 45% in customer satisfaction. System testing was conducted using the Black Box Testing method, with the evaluated indicators focusing on the Expected Results of each system function, such as respone speed, the ability to manage dynamic Workflows, and user satisfaction levels. The test results indicate that the system is fully functional and meets all expected requirements.

Abstract

Indonesian government is targeting one million halal product certification in 2023. And the government is targeting that by 2024 all products in Indonesia will be halal certified. This certainly needs support from various parties. Indonesian government through the Halal Product Assurance Organizing Agency (BPJPH) appoints the Halal Product Process Assistance Agency (LP3H) which acts as an extension and assists business actors (micro - small) through assistance in the halal certification process. However, data on the halal information system shows that only 749,971 products have been declared halal in 2022 and there is still a need for massive socialization efforts so that government programs are realized. To support this program, LP3H ITB AD conducts activities for prospective Halal Product Process (PPH) assistants to help verify and validate the halal process for business actors. The aim of the research is to disseminate basic information and knowledge to prospective PPH assistants regarding the legal basis, verification, validation, materials and processes for halal certification. The method used in this research is descriptive quantitative. Data collection was obtained from the results of the questionnaire. The results of this study show that on average 66% of the participants understand the information material related to the halal process and 79% are very satisfied with the presentation of the resource persons.

Abstract

Training and mentoring on the halal product process aims to provide understanding and skills to PPH companions, who will then pass on to business actors in applying halal principles in all stages of production, from raw materials to finished products. With appropriate training and mentoring, business actors can understand the importance of halal products and manage production well to meet halal certification requirements. In the long run, halal products will have added value because they are considered safer and more trustworthy by consumers who prioritize product quality and religious aspects. The Halal Resource Development Study and Development Center (PK-PSDH) ITB Ahmad Dahlan Jakarta carried out training and mentoring activities on May 9-12, 2022, attended by 159 participants. Based on the results of the activity, as many as 279 products have obtained their halal certification, 90 data are still in submission, 31 data are submitted, 67 data are finished with LP3H, 31 data are returned, 19 data are returned to the Fatwa Commission, 59 data are canceled, and 3 data are sent to the fatwa commission. Halal training and mentoring will continue to be carried out in the future to assist business actors in improving product quality and consumer confidence, as well as increasing business competitiveness in the global market.

Abstract

Higher education institutions must deliver high-quality education that produces graduates who are knowledgeable, skilled, creative, and competitive. In this system, students are a vital asset, and their timely graduation rate is an important factor to consider. In the department of computer science, a challenge arises in distinguishing between students who graduate on time and those who do not. With a low on-time graduation rate of just 1.90% out of 158 graduates, this issue could negatively affect the institution's accreditation evaluation. This research employs the Case-Based Reasoning method, enhanced with an indexing process using rough sets and a prediction process utilizing cosine similarity. The testing, conducted using k-fold validation with 60%, 70%, and 80% of the data, produced average accuracy rates of 64.2%, 66.3%, and 65.6%, respectively. The test results indicate that the highest average accuracy of 66.3% was achieved with 70% of the cases.

Abstract

Kota Tangerang menghadapi permasalahan genangan dan banjir akibat kondisi drainase yang belum optimal. Penentuan prioritas pembersihan drainase selama ini masih dilakukan secara manual dan cenderung subjektif, sehingga diperlukan sistem yang mampu mendukung pengambilan keputusan secara objektif dan sistematis. Penelitian ini bertujuan untuk merancang dan membangun Sistem Pendukung Keputusan (SPK) berbasis web dalam menentukan prioritas pembersihan drainase menggunakan metode AHP, SAW, dan TOPSIS. Data yang digunakan merupakan data sekunder laporan kondisi drainase tahun 2022–2024 yang diperoleh dari Dinas PUPR Kota Tangerang, dengan jumlah data awal 6.383 baris dan setelah proses cleaning menjadi 2.390 data. Pada tahap implementasi, sistem menggunakan data tahun 2024 untuk proses perhitungan. Sistem mengolah data berdasarkan kriteria teknis yang telah ditentukan dan menghasilkan skor serta peringkat alternatif pada masing-masing metode. Hasil perbandingan pada studi kasus Jl. Sempati (A3728) menunjukkan perbedaan hasil perankingan, di mana metode SAW menghasilkan peringkat ke-62, AHP peringkat ke-8, dan TOPSIS peringkat ke-4. Berdasarkan analisis tersebut, metode TOPSIS dinilai sebagai metode yang paling representatif dan optimal karena mampu memberikan hasil yang lebih sesuai dengan kondisi urgensi teknis di lapangan. Sistem ini diharapkan dapat membantu Dinas PUPR dalam menentukan prioritas pembersihan drainase secara lebih cepat, objektif, dan akuntabel.
