Abstract

Studi ini mengembangkan model matematis pada sistem distribusi jeruk dual channel. Pemodelan matematis digunakan untuk menggambarkan interaksi antarvariabel dalam sistem serta mengoptimalkan keputusan distribusi dan pengelolaan limbah secara simultan. Metode yang digunakan adalah pendekatan kuantitatif melalui pemodelan Multi-Objective Linear Programming (MOLP) yang bertujuan mengoptimalkan dua fungsi, yaitu keuntungan ekonomi dan pengurangan limbah. Modelnya mencakup dua saluran distribusi (tengkulak dan wisata petik) serta aliran balik berupa pengolahan limbah menjadi kompos. Untuk memperoleh solusi tunggal, digunakan Metode Penjumlahan Tertimbang yang menggabungkan kedua fungsi tujuan. Hasil optimasi menunjukkan bahwa seluruh distribusi dialokasikan ke saluran wisata petik sebesar 40.000 kg karena memberikan keuntungan yang lebih tinggi dibandingkan tengkulak. Limbah yang dihasilkan sebesar 6.000 kg, dengan 4.000 kg dimanfaatkan menjadi kompos dan 2.000 kg pembuangan, sehingga menunjukkan adanya upaya minimalisasi limbah dalam sistem. Hasil ini juga mengindikasikan bahwa model mampu memberikan solusi yang konsisten dan rasional sesuai dengan parameter struktur yang digunakan. Implikasi studi ini menunjukkan bahwa model yang dikembangkan dapat digunakan sebagai dasar pengambilan keputusan dalam menentukan strategi distribusi dan pengelolaan limbah yang lebih efisien. Studi pengembangan selanjutnya dapat dilakukan dengan mempertimbangkan permintaan, variasi harga, serta penggunaan metode optimasi multiobjektif lainnya untuk memperoleh solusi yang lebih kuat.

Abstract

Perkembangan e-commerce mendorong peningkatan aktivitas Last Mile Delivery, khususnya pada sistem pembayaran Cash On Delivery (COD) yang memiliki tingkat risiko tinggi bagi kurir. Studi ini bertujuan untuk membangun model simulasi guna menganalisis risiko kurir serta mengevaluasi dampak kebijakan Re-attempt Delivery dalam pengiriman COD. Metode yang digunakan adalah pendekatan kuantitatif dengan simulasi System Dynamics. Data diperoleh melalui observasi dan wawancara selama periode September 2025 hingga Februari 2026. Model dikembangkan menggunakan Causal Loop Diagram dan Stock Flow Diagram, kemudian disimulasikan dalam dua skenario, yaitu tanpa dan dengan penerapan Re-attempt Delivery. Hasil simulasi menunjukkan bahwa peningkatan volume pengiriman COD menyebabkan kenaikan jumlah paket bermasalah. Pada skenario tanpa kebijakan, paket bermasalah meningkat signifikan. Sementara itu, penerapan Re-attempt Delivery mampu menurunkan jumlah paket bermasalah, dari 9.570 menjadi 6.699 pada awal periode dan dari 20.440 menjadi 14.308 pada akhir periode simulasi. Selain itu, jumlah paket yang berhasil dikirim ulang bisa meningkat secara konsisten.

Abstract

Improving public satisfaction and reuse intention in social life requires new innovations, namely KKN. The KKN Blue Ocean Innovation integrated capstone design model integrates education, development, service, and community empowerment outside the campus environment. The proposed model, based on the stimuli-organism-response theory and the KKN framework, which integrates the four aforementioned student roles (catalyst, process helper, solution giver, and source linker) to study the intention reuse KKN. Valuable insights for implementing KKN to be accepted by the community are to prioritize community satisfaction as the object of study in integrating more innovative KKN concepts. Partial least squares structural equation modeling (PL-SEM) with a survey of 50 community members and students who have interacted and experienced community service (KKN) was used. Results: This study found that the solution giver dimension dominated the role of students as agents of change compared to the catalyst (C); process helper (PH); solution giver (SG); and sources linker (SL), which were 16%, 20%, 50%, and 14%, respectively. SL dominated the role of students as agents of change. The mediation analysis explains that community satisfaction mediates the relationship between the four dimensions and KKN reuse intention. The role of student agents of change includes raising community awareness and enthusiasm to change and develop SL for the better. The direct and indirect influence of the agent of change dimension on public satisfaction and reuse intention is a novelty of this study.

Abstract

ABSTRACT In this study, a chili supply chain model based on agent-based simulation (ABS) is designed. ABS is a simulation method that models how individual agents interact to understand a system’s overall behavior. This study aims to test the SCR model and assess the impact of policies such as fertilizer subsidies and price information disclosure on distribution efficiency. The stages for building the ABS model begin with identifying obstacles through questionnaires and observations and modeling, five agents: farmers, collectors, distributors, consumers, and the government. The modeling uses NetLogo software, which is used to build the ABS model with two scenarios. The scenarios considered (1) a model without fertilizer subsidies and price information and, (2) a model with subsidies and price information. The simulation results show that the scenario using fertilizer subsidies and price information is more effective by reducing delivery lead time by 69.6 hours and loss rates by 14%, increasing farmer margins by 50%, and reaching 92% service levels. Model validation in the second scenario reduced prices by approximately 28%. The model’s’ implications can be used by the government in creating food price stabilization policies to maintain food security. Future work on food security models could include integrating digital technologies such as IoT, blockchain, or e commerce to simulate supply chain real-time traceability. ABSTRAK Studi ini mendesain model supply chain cabai berbasis Agent Based Simulation (ABS). ABS merupakan metode simulasi yang memodelkan bagaimana agen individu saling berinteraksi untuk memahami perilaku keseluruhan sistem. Tujuannya adalah untuk menguji model ketahanan supply chain dan menilai dampak kebijakan seperti subsidi pupuk serta keterbukaan informasi harga terhadap efisiensi distribusi. Tahapan untuk membangun model ABS dimulai dari mengidentifikasi hambatan melalui kuesioner dan observasi, serta pemodelan lima agen yaitu petani, pengepul, distributor, konsumen, dan pemerintah. Pemodelan menggunakan perangkat lunak NetLogo yang digunakan untuk membangun model ABS dengan dua skenario. Skenario tersebut mempertimbangkan (1) model tanpa subsidi pupuk dan informasi harga, dan (2) Model dengan subsidi dan informasi harga. Hasil simulasi menunjukkan bahwa skenario yang menggunakan subsidi pupuk dan informasi harga berjalan lebih efektif dengan menurunkan lead time pengiriman sampai 69.6 jam dan kerusakan produk (losses rate) sebesar 14%, margin petani meningkat sebesar 50%, serta service level mencapai 92%. Validasi model pada skenario kedua menurunkan harga sekitar 28 %. Implikasi model dapat digunakan oleh pemerintah dalam menciptakan kebijakan stabilitasi harga pangan sehingga mampu menjaga ketahanan pangan. Arah pengembangan model ketahanan pangan kedepan dengan mengintegrasikan dimensi teknologi digital seperti IoT, blockchain, atau e-commerce untuk mensimulasikan ketelusuran waktu nyata dalam supply chain.

ABSTRACT  This study examines the daily risk variability faced by crowd agents in cash on delivery (COD) transactions. Using a dataset of 30 couriers, this study aimed to identify the most dominant risk dimensions during package delivery via the COD method. This study applies a risk analysis of couriers performing COD using a hybrid method: (i) Fuzzy logic is used to eliminate the uncertainty and subjectivity of expert assessments, and (ii) AHP is focused on determining the dominant risks. The findings of this study indicate that 6 dimensions contribute to the formulation. Risks were prioritized across six dimensions: fictitious addresses, payment refusal, loss of COD cash, threats of violence, reputation, and re-attempt delivery. Field validation was conducted by interviewing experts with of experience. The implications of this study serve as a roadmap for academics to further develop digital payment models, and for online retailers and policymakers to integrate digital payments with consumer trust preferences to achieve digital financial inclusion in Indonesia. Future development should integrate sustainable dimensions (economic, environmental, and social) and delivery technology-based approaches.
