Abstract

Logistics management is known as distribution and transportation management, while others call it physical distribution management. Distribution activities are very important for companies to deliver a product to consumers across various regions. The Regional Drinking Water Company (PDAM) Tirta Binangun Kulon Progo is one of the companies that produce Bottled Drinking Water (AMDK) under the product name AirKu. The high demand for AMDK AirKu products in 240 ml cup packaging was causing limited vehicles and the absence of a clear standard distribution route, which caused the distribution process to be carried out randomly. Therefore, to overcome the company's problems, it is possible to determine the Vehicle Routing Problem (VRP) route with the CVRP approach, where the route determination is based on fleet capacity. The method used was tabu search using the MATLAB application to minimize the bottled product delivery route traveled. The results obtained were the total distance traveled by 284.9 km. The proposed route had a distance savings of 118.26 km, which is better than the company route.

Abstract

In the context of flood risk mitigation in Yogyakarta City, particularly in the districts of Gondokusuman and Umbulharjo, this study highlights the significant impact of geographical factors and high rainfall intensity. Floods not only cause damage to infrastructure but also pose a serious threat to public health. Flood-prone areas often become breeding grounds for diseases that can spread rapidly, especially in emergency conditions. This research aims to identify optimal routes for the distribution of health logistics in dealing with flood disasters in Yogyakarta City. Using the Simulated Annealing (SA) algorithm, the study compares the optimization results of distribution routes without clustering and with clustering (based on districts). Findings indicate that the use of clustering is effective in minimizing the distance and travel time of distribution, with the clustering scenario emphasizing time efficiency. The contribution of this research lies in the development of responsive and efficient health distribution strategies during flood emergencies. Thus, the implementation of the SA algorithm and clustering can serve as a foundation for better emergency response planning, providing tangible benefits for those involved in flood disaster management in the region.

Abstract

Aktivitas pengiriman sangat penting bagi perusahaan untuk menyampaikan suatu produk kepada konsumennya yang tersebar di berbagai wilayah. Pemilihan metode penentuan rute secara tepat harus dilaksanakan oleh perusahaan agar produk cepat sampai serta biaya distribusinya minimal. Pada pengiriman produk gula pasir oleh Perum BULOG DIY GBB Purwomartani ke wilayah Kabupaten Sleman dan Kota Yogyakarta belum berdasarkan metode tertentu yang spesifik sehingga hasilnya dinilai belum optimal. Tujuan dari penelitian ini adalah untuk menentukan rute distribusi pada perusahaan tersebut dengan jarak tempuh minimum menggunakan metode Clarke and Wright Savings dan Nearest Neighbor. Kedua metode tersebut mampu mengurangi jarak tempuh yang semula 372,3 km menjadi 178,1 km dari hasil Clarke and Wright Savings dan 173,1 km dari hasil Nearest Neighbor. Biaya distribusi yang semula Rp1.528.038,88 juga dapat dihemat hingga mencapai lebih dari 50% yaitu sebesar Rp702.380,125 dari hasil Clarke and Wright Savings dan Rp697.598,880 dari hasil Nearest Neighbor.

Abstract

Stingless bee (Trigona sp.) farming training serves as a practical and contextual strategy to foster entrepreneurial spirit among students in Islamic boarding schools. This activity was carried out at Oemah Jampi for the students of Isy Karima Islamic Boarding School with the aim of providing technical understanding of stingless bee (Trigona) farming and fostering business motivation based on local potential. The training encompassed educational sessions, hands-on technical workshops, practical field activities, and evaluations through pre- and post-tests. Results indicated a significant increase in participants' understanding, with average scores rising from 48.3 to 84.6. Additionally, students proposed simple business ideas, such as producing packaged honey and developing derivative products. The enthusiastic response from participants and the conducive environment of the boarding school suggest that stingless bee farming holds substantial promise as a medium for practical entrepreneurship education. This training not only transferred technical skills but also successfully instilled a sense of economic independence aligned with the boarding school's character. Similar training models have the potential to be replicated in other Islamic boarding schools as part of developing students' creative economies.

Abstract

This study aims to design a halal supply chain model for Joper chicken by integrating the Halal Assurance System (HAS 23000), the Indonesian National Standard for halal poultry slaughtering (SNI 99002:2016), and the Supply Chain Operations Reference (SCOR) model. The research identifies ten Halal Critical Points (HCPs) along the supply chain from upstream to downstream. Through direct observation, interviews with stakeholders (farmers, brokers, poultry slaughterhouse operators, and restaurant owners), and literature review, this study identifies potential risks that could threaten halal status. A total of 31 risk events were mapped using the guidelines from SNI 99002:2016. The SCOR model was then applied to systematically structure the halal supply chain framework based on five pillars: Plan, Source, Make, Deliver, and Return. The result is a comprehensive and integrated halal supply chain model that enhances traceability, control, and assurance of halal integrity in the Joper chicken business processes. The proposed halal supply chain model enhances traceability, halal quality control, and risk management across all stages. This model serves as a valuable reference for industry practitioners and policymakers to strengthen halal assurance systems in Indonesia's poultry sector.

Abstract

Limbah Tankos atau Tandan Kosong dari kelapa sawit adalah satu jenis limbah padat dari kelapa sawit, jumlahnya terus meningkat seiring dengan bertambahnya aktivitas produksi CPO. Setelah menjadi CPO sebagai bahan baku, kemudian CPO disimpan dalam tangki-tangki timbun sebelum siolah menjadi produk turunan (Mulyadi et al., 2023). Setiap proses produksi CPO tidak terlepas dari limbah terutama limbah tandan kosong (tankos). Menurut (Septiawan et al., 2014) strategi penghematan pupuk kimia dan perbaikan berkelanjutan dengan pemanfaatan limbah padat dan pengurangan limbah B3. Hal ini menimbulkan berbagai permasalahan, seperti penumpukan limbah padat pada pabrik CPO, penurunan estetika lingkungan, dan dampak negatif terhadap kesehatan serta lingkungan akibat pengelolaan yang tidak tepat, seperti pembakaran tangkos yang menyebabkan polusi udara dan kontribusi pada pemanasan global. Selain itu, rendahnya kesadaran masyarakat dan kurangnya pengetahuan mengenai alternatif pengolahan tangkos sering kali di biarkan begitu saja. Rendahnya kesadaran masyarakat dan kurangnya pengetahuan mengenai alternatif pengolahan limbah tangkos memperparah situasi ini. Mengatasi permasalahan tersebut, program pelatihan dan pendampingan daur ulang tangkos menjadi pupuk organik merupakan solusi inovatif yang mudah dilakukan. Tujuan program ini mengintegrasikan edukasi lingkungan, pelatihan teknologi tepat guna, dan pengembangan kreativitas serta kewirausahaan. Kegiatan ini melibatkan warga desa Padang Luas, Langgam sebagai target utama dengan pendekatan berbasis partisipatif dan praktik langsung. Metode pelaksanaan kegiatan memiliki beberapa tahapan antara lain: Tahap sosialisasi dan penyuluhan, Tahap pelaksanaan pembuatan kompos tangkos dan Tahap refleksi kegiatan.

Abstract

Cabai merah merupakan komoditas penting yang dapat menunjang perekonomian dan kebutuhan pangan masyarakat. Oleh sebab itu, kepedulian instansi pertanian agar masyarakat mampu berswadaya untuk menanam cabai pun tinggi. Hal ini ditunjukkan dengan pemberian bantuan benih tanaman cabai kepada pemerintah Kota Yogyakarta untuk diberikan kepada sejumlah kelompok tani di wilayah tersebut. Bantuan tanaman benih cabai akan dilakukan secara continue maka dari itu penentuan rute distribusi yang optimal diperlukan untuk dapat menjaga kualitas bibit yang disalurkan. Penelitian ini menggunakan metode Simulated Annealing (SA) untuk menentukan rute terpendek dalam proses distribusi bibit cabai. Hasil yang diperoleh dari penentuan rute distribusi dengan menggunakan metode Simulated Annealing (SA) yang menerapkan 3 kombinasi parameter dan replikasi sebanyak 5 kali menunjukkan hasil terbaik berupa rute dengan total jarak tempuh yaitu 26,14 km dengan estimasi waktu distribusi yaitu 1 jam 12 menit. Hasil tersebut diperoleh dari penerapan parameter Simulated Annealing (SA) dengan nilai suhu awal (T0) = 50, suhu akhir (TF) = 0,001 dan koefisien pendinginan (α) = 0,99 pada replikasi ke 2. Dengan hasil ini maka jika diterapkan dalam kasus distribusi bibit cabai akan membuat proses pengirimannya menjadi lebih cepat karena memiliki jarak yang minimal.
