Abstract

Produk perishable memiliki masa simpan terbatas, sehingga diperlukan metode tertentu untuk mempertahankan kualitasnya. Tantangan utamanya adalah menentukan jumlah pasokan yang dibutuhkan sebelum produk tersebut kedaluwarsa. Penelitian ini bertujuan memaksimalkan keuntungan dengan mempertimbangkan penurunan kualitas produk. Model yang digunakan melibatkan dua fase persediaan: fase pertama untuk menyimpan cabai segar, dan fase kedua untuk menyimpan cabai kering. Sumber pasokan hanya berasal dari satu jenis, yaitu cabai segar, yang digunakan untuk memenuhi dua jenis permintaan berbeda. Proses yang disebut renewal process dilakukan melalui pengeringan, yang dapat memperpanjang masa simpan produk. Sisa produk dari fase pertama dapat diproses lebih lanjut melalui renewal. Selain itu, penelitian ini juga mempertimbangkan kendala emisi karbon selama penyimpanan cabai segar. Terdapat dua skenario yang merepresentasikan kondisi sistem nyata: skenario pertama dengan permintaan tetap dan skenario kedua dengan permintaan fluktuatif. Hasil penelitian menunjukkan perbedaan signifikan antara kedua skenario dalam hal efisiensi dan adaptabilitas. Skenario pertama lebih hemat biaya karena total biayanya lebih rendah, terutama pada biaya inventori (Rp 185.593 dan Rp 204.784), dan jumlah inventori lebih kecil, sehingga cocok untuk permintaan yang stabil. Sebaliknya, skenario kedua lebih adaptif terhadap permintaan yang fluktuatif meskipun total biayanya lebih tinggi.

Abstract

The research gap that this study aims to fill is: increasing the reliability of the previously created simulation model and adopting a representation of uncertainty in the Basic Robochop production process time. This study analyzes the production process time of one basic Robochop unit using ARENA software-based simulation. The Basic Robochop (seven units) is modeled using an activity cycle diagram representing the arrival of its components based on historical data. The model then integrates the components into the production process until completion. The time between the arrival of 50 components of one Basic Robochop product is modeled with a random EXPO(1) minute, the 50 components are then assembled in the Basic Robochop production process which is modeled based on historical data of the previous manufacture of 7 Robochops with one worker, namely 129 + EXPO(1,380) minutes. The model produces a square error value of around 3%. The optimal number of replications obtained was 1,833, after five initial replications were carried out randomly. The simulation results show a decrease in process time from 24,670 minutes to 1,096 minutes in the alternative scenario.

Abstract

The discrepancy between actual cycletimeand production targets may affect the stability and efficiency of the cooking oil packaging process. This study aims to analyze the cycletimeof Machine S in the FillingPlantof PT XYZ Tbk. Surabaya for 485 ml packaging production and to evaluate process stability against company standards. The method employed was a timestudy conducted through direct measurements using a stopwatch, supported by production data from June 2025, machine target data, and process production data. The results indicate that the actual cycletimeof 15 seconds per unit is lower than the company’s takttimeof 15.7 seconds per unit, demonstrating that the production process is capable of meeting the target of 1,720 bottles per shift. These findings suggest that the fillingplantsystem operates stably in accordance with established operational standards. This research serves as both an evaluation of process timeperformance and a validation of time-based production control implementation. The results are expected to provide a foundation for continuous monitoring and contribute to future studies on productivity and efficiency in manufacturing packaging lines.

Abstract

One of the primary goals of the youth organization (Karang Taruna) is to foster an entrepreneurial spirit and promote independence as part of efforts to improve social welfare. Some members of the Babat youth organization proposed a business idea: a personal shopping service (Jastip). However, there are several areas for improvement in their current jastip business model, including limiting their products to specific categories (such as cosmetics or skincare), operating only during major events or bazaars, lacking effective business management, and not utilizing social media for promotion. The identified improvement priorities include providing training on service management and online promotion strategies, creating and actively managing social media accounts, and diversifying the range of products offered. Each activity is closely monitored and evaluated based on pre-determined performance indicators. The outcomes of this community service project include the establishment of an Instagram account for the jastip business, clear delegation of responsibilities among members, the creation of structured schedules for shopping and promotion, and the addition of new product categories to their inventory. The community service activities were successfully implemented and received enthusiastic participation from all members.

Abstract

Desa Ngulan Wetan, Kecamatan Pogalan, Kabupaten Trenggalek merupakan wilayah agraris dengan potensi limbah organik melimpah, seperti sekam padi, serbuk kayu, daun kering, dan kulit jagung. Selama ini, limbah tersebut hanya dibakar atau ditumpuk sehingga menimbulkan masalah lingkungan dan menyia-nyiakan potensi ekonominya. Di sisi lain, masyarakat menghadapi kebutuhan akan bahan bakar alternatif yang lebih ekonomis dan ramah lingkungan, mengingat harga LPG dan arang kayu yang tidak stabil. Menanggapi permasalahan tersebut, tim pengabdian dari Program Studi Teknik Industri Universitas Katolik Darma Cendika menginisiasi program pemberdayaan masyarakat melalui pelatihan pembuatan briket dari limbah organik. Program ini bertujuan memberikan solusi terintegrasi mulai dari peningkatan pengetahuan, penyediaan alat sederhana dan teknologi tepat guna, hingga pendampingan dalam manajemen usaha dan pemasaran. Pelatihan mencakup seluruh proses produksi briket: pengumpulan dan pengeringan limbah, karbonisasi, pencampuran dengan perekat alami, pencetakan, dan pengeringan akhir. Teknologi yang digunakan sederhana dan berbasis sumber daya lokal, sehingga mudah diadopsi masyarakat. Hasil program menunjukkan peningkatan pengetahuan dan keterampilan warga secara signifikan. Kelompok warga yang terlibat mampu memproduksi rata-rata 12 kg briket per bulan, melebihi target awal. Sebagian hasil produksi juga berhasil dipasarkan, menambah pendapatan keluarga sebesar 10–15%. Selain manfaat ekonomi, terjadi perubahan perilaku masyarakat dalam pengelolaan limbah, dari sebelumnya dibakar menjadi produk bernilai. Program ini juga meningkatkan kesadaran akan pentingnya energi terbarukan dan pelestarian lingkungan.

Abstract

Sector Logistics plays an important role in maintaining the smoothness and efficiency of national and global supply chains, especially for third-party logistics ( 3PL ) service providers who face demands for reliability and speed of service amidst global competition. The complexity of the logistics process creates the need for a structured and measurable performance evaluation model. This study aims to apply the Supply Chain Operations Reference ( SCOR ) model in identifying and prioritizing key performance indicators ( KPI ) in a 3PL company . The method used involves distributing questionnaires to decision makers in operational and managerial fields. The weights of SCOR performance attributes including reliability, responsiveness, flexibility, cost measures, and asset management efficiency are calculated using the Fuzzy Analytic Hierarchy Process ( FAHP ) method. Furthermore, the Technique for Order Preference by Similarity to Ideal Solution ( TOPSIS ) is used to determine KPI priorities at PT.X. The results of the study show that there are 17 indicators to measure the performance of the freight forwarding sector with the largest weight being operator reliability (0.251) on the reliability attribute, the number of on-time deliveries (0.694) on the responsiveness attribute, load flexibility (0.317) on the flexibility attribute, shipping costs per km (0.379) on the cost attribute and cash-to-cash cycle time (0.479) on the asset management attribute. The SCOR model has proven effective as an initial framework in measuring the performance of 3PL logistics service providers, because it is able to integrate various aspects of performance systematically and quantitatively.
