Penelitian ini dilatarbelakangi oleh tingginya biaya penyimpanan dan meningkatnya stok mati pada Delyana Hijab, yang menunjukkan belum optimalnya pengelolaan persediaan bahan baku. Ketidaksesuaian antara jumlah bahan baku dan kebutuhan produksi menyebabkan pemborosan biaya serta menurunkan efisiensi operasional. Penelitian ini bertujuan untuk menentukan kebutuhan material yang optimal melalui pendekatan forecasting dan Material Requirement Planning (MRP). Metode yang digunakan adalah deskriptif kuantitatif dengan teknik pengumpulan data berupa observasi, wawancara, dan dokumentasi. Tahapan analisis meliputi peramalan permintaan, penyusunan Master Production Schedule (MPS), Bill of Materials (BOM), perhitungan kebutuhan bersih (MRP), serta penentuan ukuran pemesanan melalui metode lot sizing. Hasil penelitian menunjukkan bahwa metode regresi linier menghasilkan tingkat kesalahan peramalan terendah sehingga mampu memproyeksikan kebutuhan produksi dengan lebih akurat. Penerapan MRP menghasilkan perencanaan kebutuhan bahan baku yang lebih terarah dan sesuai dengan jadwal produksi. Pada tahap lot sizing, metode Lot For Lot (LFL) menjadi yang paling efisien dengan total biaya persediaan sebesar Rp108.669.000. Dalam penerapannya, jumlah pemesanan bahan baku mengikuti kebutuhan bersih tiap periode, misalnya kebutuhan kain katun berkisar 5-7 roll per minggu dan dipesan dalam jumlah yang sama tanpa kelebihan stok. Pola ini mampu menekan penumpukan persediaan dan mengurangi risiko stok mati karena bahan baku langsung digunakan sesuai kebutuhan. Dengan demikian, tujuan penelitian untuk menentukan kebutuhan material yang optimal telah terjawab melalui penerapan metode Lot For Lot yang mampu menghasilkan kuantitas pemesanan yang tepat dan efisien.

Education in the modern era requires students not only to master cognitive knowledge, but also to have the ability to think critically, analytically, creatively, and problem solving skills independently. Therefore, the application of the Problem Based Learning (PBL) model and the Learning Strategy for Improving Thinking Ability (SPPKB) is considered relevant and ideal in the context of Christian Religious Education (PAK) to integrate faith values with the reality of daily life. This study uses a literature study method by examining scientific journals, books, and academic articles to analyze the definition, essence, characteristics, and steps of PBL which include the introduction of authentic cases, problem solving, investigation planning, independent learning, solution synthesis, presentation of results, and reflection. PBL has proven to be effective in increasing learning motivation, collaboration, and internalization of Christian moral values, although it has limitations in the relatively long time requirement and the demands of teacher competence as facilitators. Meanwhile, SPPKB emphasizes intellectual stimulus, exploration of ideas, data processing, in-depth analysis, and metacognitive reflection to form a systematic and independent mindset in dealing with religious ethical issues. These two student-centered learning strategies complement each other in forming students who are dynamic, reflective, critical, and responsible as Christian personalities through flexible and contextual learning adaptations in PAK.

Managing Regional Public Service Agency (Badan Layanan Umum Daerah/BLUD) hospitals requires planning and budgeting processes that are accountable, measurable, and aligned with service performance. In practice, BLUD planning is still constrained by fragmented applications (hospital information system/SIMRS, finance, human resources, e-office, and procurement), duplicate data entry, approval delays, and limited monitoring of process compliance. This study aims to analyze requirements and design a web-based BLUD planning information system using an Enterprise Application Integration (EAI) approach through middleware to improve cross-system interoperability, data consistency, and the timeliness of executive reporting. The study adopts the Design Science Research (DSR) framework, comprising problem identification, definition of solution objectives, artifact design and development, demonstration, evaluation, and communication/report writing. The proposed system includes a unit-based budget proposal module and item management, a role-based approval workflow (RBAC) with SLA tracking, a budget ceiling (pagu) master to benchmark proposals, audit trails and report exports, and an executive dashboard integrating budget perspectives, service indicators (e.g., bed occupancy rate/BOR and patient visits), and process compliance. It also provides an integration design via middleware (ESB/message broker) supported by a canonical data model (CDM) and traceable logging (trace_id/correlation_id). Evaluation using black-box testing and API contract testing indicates that the main planning workflow operates as intended and the integration interfaces are consistently defined, providing a foundation for staged implementation and further performance evaluation.

This community service activity aims to integrate theory and practice through the construction of simple shelters by the academic community of the Vocational Program at Gorontalo State University. The activity is motivated by the need to improve the technical competence and social skills of building architecture students. The method used is participatory action learning, involving students and faculty members from planning to evaluation. The activities include group division, case studies at brick and block factories, construction of the lower, middle, and upper structures, and final assessment. The results showed that 70% of students mastered construction skills in accordance with simple building standards, with the final product being a functional shelter. The main challenges faced were team coordination and time management. Discussions confirmed that this model is effective in enhancing technical skills, teamwork, and understanding of sustainable construction, and is worth replicating in other vocational programs. The shelter construction also provided an opportunity to reflect on real-world applications of architectural theory, while addressing pressing community needs. Through active participation, students gained firsthand knowledge in applying design concepts and construction techniques that are crucial to the construction industry. Furthermore, the activity demonstrated the potential for developing students' abilities to apply architectural concepts that are not only relevant to academic requirements but also to practical, community-based construction needs. The project also emphasized the importance of sustainable building practices, focusing on materials and methods that minimize environmental impact. The construction of the shelter not only provided practical experience but also enriched students' knowledge in creating environmentally friendly and sustainable construction solutions.

CV XYZ is a company engaged in manufacturing with production in the form of stacking chairs. This company has a production capacity of 200 units of stacking chairs every day. The company has 3 types of bunk chairs, namely CH-100 KR, CH-200 KR, and CH-200 PC. Customer demand at this company tends to be fluctuating (up and down) which results in the company experiencing difficulties in determining the optimal raw material inventory to meet customer needs. The Material Requirement Planning (MRP) method is an appropriate method for scheduling inventory. The result of this scheduling model is in the form of a master production schedule (JIP) which is used to determine the demand for chair products for the next 6 months. The results of data processing obtained requests for stacking chairs in the next 6 months for the type CH-100 KR 10.724 unit, CH-200 KR of 10.998 unit, and CH-200 PC of 9.687 unit. The demand is then calculated using the MRP approach with LFL and EOQ. An effective material requirements planning method with the lowest cost is to use the Lot For Lot (LFL) method which gives the lowest cost results IDR 7,475,617,611.

Company CV. AM Nanda Putra is located in Sidoarjo and operates in the scaffolding industry. Currently the company is experiencing losses due to a lack of optimization in planning the amount and time of ordering raw materials, which results in shortages and excess material inventory. To overcome this problem, the company uses the MRP (Material Requirement Planning) method in optimizing raw material planning. In terms of the lot sizing approach, the company applies the LFL and EOQ methods. The forecasting methods used are Moving Average (MA), Weight Moving Average (WMA), and Exponential Smoothing (ES). The smallest MAD results were obtained using the Exponential Smoothing (ES) method for all scaffolding products. The forecasting results are obtained to determine the MPS (Master Production Schedule) for the next 10 months. After the determination of  MPS, the results of Material Requirement Planning (MRP) were obtained, namely the supply of raw materials for MF 170 AM scaffolding of 35402 units or 17700 sets, MF 170 K1 scaffolding of 28906 units or 14453 sets, MF 190 AM scaffolding of 16250 units or 8125 sets, and MF 190 K1 scaffolding of 7656 units or 3828 sets. From the results of calculating the cost of raw material requirements using the Lot for Lot (LFL) method and the Economic Order Quantity (EOQ) method, it can be seen that the total cost of planning the smallest raw material inventory with an amount of Rp. 12,975,818,022.
