Abstract

PT. Eastern Pearl Flour Mills – City Side Makassar affects land use changes that have an impact on changes in traffic movement, so traffic impacts analysis is needed. The purpose of this study is to identify the performance of affected roads and intersections in the present and in the next 5 years, to handle traffic problems and conflicts by simulating models without handling (Do Nothing) and with handling (Do Something), analyzing time delays on the U-turns and modeling the origin-destination matrix using the Furness Method. This study uses qualitative and quantitative analysis methods that refer to the Manual Kapasitas Jalan Indonesia (MKJI, 1997) and The Furness method. The results of the analysis of the level of service on the Jl. The archipelago is in fairly good condition with LoS values A to B and DS 0.11 – 0.40 with a speed of 26.60 – 50.00 km/hour, the road performance that has the worst impact occurs at the Tol Reformasi – Jl. Nusantara with a projection for the next 5 years in 2027, where road performance has a LoS E and DS value of 0.88 with a delay time of 19 seconds/pcu. U-turn facility on Jl. Nusantara has an average delay time of 6.16 – 7.82 seconds for one rotating vehicle with a value of < 1 so that there is no queue. The results of the trip distribution analysis using The Furness model obtained the same value of generation and attraction in the second iteration, which means that it is still close to ideal conditions.

Abstract

Beras merupakan komoditas strategis yang memainkan peran penting dalam ketahanan pangan dan stabilitas ekonomi, sehingga pengelolaannya membutuhkan transparansi untuk mewujudkan tata kelola pemerintahan yang baik (good governance). Masalah distribusi beras yang tidak merata dan biaya distribusi tinggi masih menjadi tantangan signifikan. Penelitian ini bertujuan untuk menganalisis model kemitraan yang melibatkan Majelis Ekonomi Perserikatan Muhammadiyah dalam meningkatkan kinerja distribusi beras. Metode yang digunakan adalah Structural Equation Modeling - Partial Least Squares (SEM-PLS) untuk memodelkan hubungan antara koordinasi kemitraan, komitmen kemitraan, pembagian risiko, akses pasar, dan dukungan organisasi terhadap kinerja distribusi beras. Pengumpulan data dilakukan melalui kuesioner dan wawancara mendalam dengan 75 petani yang bermitra dengan Majelis Ekonomi Perserikatan Muhammadiyah di Kabupaten Sidenreng Rappang. Hasil penelitian menunjukkan bahwa setiap variabel yang dianalisis, seperti koordinasi kemitraan, komitmen kemitraan, pembagian risiko, dan akses pasar, memiliki pengaruh yang signifikan terhadap kinerja distribusi beras. Koordinasi yang baik antar pemangku kepentingan meningkatkan efisiensi distribusi, sementara komitmen kemitraan memperkuat dukungan organisasi dan mengurangi biaya operasional. Pembagian risiko yang transparan mempercepat distribusi dan mengurangi ketidakpastian dalam rantai pasokan. Akses pasar yang lebih luas memperkuat posisi petani dalam rantai distribusi dan memungkinkan distribusi beras lebih cepat dan stabil. Penting untuk memperkuat kemitraan antara pemangku kepentingan dan meningkatkan infrastruktur serta akses pasar untuk efisiensi distribusi beras.

Abstract

Rice is the main staple food in Indonesia, and Sidenreng Rappang District contributes significantly to rice production in South Sulawesi Province. However, rice distribution in this area faces significant challenges, including long marketing channels and high marketing margins, which disadvantage farmers. The Muhammadiyah United Economic Assembly plays an important role in optimizing distribution channels, providing access to financing to farmers, and facilitating cooperation between farmers and marketing institutions. This research used observation, interview, and documentation methods, with primary and secondary data. The results showed that the marketing margin of rice in Sidenreng Rappang District reached IDR 23,650/kg, with the largest profits enjoyed by wholesalers and retailers. Improving more efficient distribution channels can reduce marketing margins and improve farmers' welfare. Therefore, the role of the Economic Assembly of Muhammadiyah Association is crucial in creating a more efficient trade system and improving the economic welfare of the people in Sidenreng Rappang District.

Abstract

Logistics operations, particularly loading and unloading (L/U) activities within warehouses, constitute critical components of the supply chain. Parepare City, a logistics hub in Indonesia, faces operational challenges including prolonged waiting times and facility constraints, leading to goods congestion and diminished L/U productivity. This study aims to characterize warehouse facilities and freight transport modes while quantitatively measuring cargo handling productivity. Employing a mixed-methods approach, data were collected via field observations (including timed L/U cycles), questionnaires, and documentation across four mechanized warehouses (three commercial, one steel material facility). Multiple linear regression analysis (SPSS v.26) was applied. Field measurements revealed peak productivity at the steel warehouse (51 pieces/minute, negligible waiting time), contrasting with significant variability and extended waiting periods (e.g., 119 minutes) observed in commercial warehouses. Regression analysis identified the quantity of goods (X1), equipment performance (X2), and L/U time (X3) as statistically significant predictors of productivity (Y). The strongest model (R² = 79.5%) was derived for the steel warehouse. The study concludes that strategic investment in mechanical handling equipment and enhanced scheduling protocols are imperative to mitigate waiting times and elevate overall productivity. Its novelty resides in addressing a significant gap in the regional logistics literature through an empirical focus on Parepare's unique warehouse operations.

Abstract

The behavior of long-haul truck drivers is shaped by the weak enforcement of working-hour rules, tight deadlines, and heavy workloads. Over-dimensioning and overloading practices further increase risks by forcing drivers to handle excessive loads and work for prolonged periods. This study predicts speeding behavior among long-haul freight truck drivers using statistical and machine learning models. Data was collected from 370 respondents at two weigh stations in South Sulawesi, Indonesia, covering eight socio-demographic, economic, and operational predictors. Three models were tested: Binary Logistic Regression (BLR), Random Forest (RF), and Extreme Gradient Boosting (XGBoost). The dataset was balanced and split into 70% training and 30% testing, with performance assessed using accuracy, recall, F1-score, and AUROC. XGBoost delivered the best results, achieving 97.3% accuracy, 93.2% recall, a 96.4% F1-score, and a perfect AUROC of 1.000. RF also showed strong performance with 94.05% accuracy and an AUROC of 0.973, while BLR served as a relevant baseline despite weaker predictions. Key predictors of speeding violations were daily sleep duration, monthly income, and driving experience. This study demonstrates how machine learning can be effectively integrated alongside transportation data under imbalanced conditions, providing evidence-based insights to strengthen freight transport safety.

Abstract

Tradisi massompe’ atau merantau merupakan bagian penting dari budaya masyarakat Bugis di Sulawesi Selatan yang turut membentuk pola mobilitas dan pemilihan moda transportasi. Penelitian ini bertujuan menganalisis perilaku perjalanan dan preferensi moda transportasi masyarakat Bugis perantau berdasarkan karakteristik demografis. Metode yang digunakan adalah deskriptif kuantitatif melalui survei terhadap 300 responden dari lima wilayah konsentrasi Bugis: Barru, Parepare, Pinrang, Sidenreng Rappang, dan Enrekang. `we`asil penelitian menunjukkan bahwa mayoritas responden berada pada usia produktif dengan distribusi gender yang relatif seimbang. Moda transportasi darat seperti mobil pribadi (40,3%) dan sepeda motor (31%) menjadi pilihan utama karena fleksibilitas dan efisiensi. Tujuan perjalanan didominasi oleh kebutuhan bekerja (49,3%) dan pendidikan (36%), sementara alasan sosial-budaya seperti silaturahmi hanya 15,3%. Faktor demografi seperti usia, pendapatan, dan asal domisili berpengaruh signifikan terhadap pilihan moda. Temuan ini menegaskan bahwa kebijakan transportasi yang kontekstual dan inklusif perlu mempertimbangkan budaya lokal dan kondisi sosial-ekonomi, khususnya dalam mendukung mobilitas masyarakat perantau di wilayah Indonesia Timur.

Abstract

Cuaca ekstrem menjadi salah satu tantangan utama dalam sistem distribusi logistik, terutama pada jalur angkutan barang non-perkotaan di wilayah Indonesia timur. Penelitian ini bertujuan untuk menganalisis pengaruh kecepatan, waktu tempuh, keselamatan, dan biaya transportasi terhadap perilaku distribusi angkutan barang dengan mempertimbangkan peran cuaca ekstrem. Metode penelitian menggunakan pendekatan kuantitatif dengan Structural Equation Modeling-Partial Least Squares (SEM-PLS), berdasarkan data kuesioner dari 300 pengemudi truk di UPPKB Datae dan Maccopa, Sulawesi Selatan. Hasil analisis menunjukkan bahwa keselamatan (p = 0,021) dan biaya transportasi (p = 0,001) berpengaruh signifikan terhadap perilaku distribusi. Sebaliknya, kecepatan, waktu tempuh, dan cuaca ekstrem tidak memberikan pengaruh signifikan. Nilai koefisien determinasi (R² = 0,01) mengindikasikan bahwa model hanya mampu menjelaskan 1% variasi perilaku distribusi, sehingga terdapat faktor eksternal lain di luar model yang lebih dominan memengaruhi distribusi logistik. Temuan ini menekankan pentingnya strategi peningkatan keselamatan dan efisiensi biaya sebagai prioritas utama dalam menghadapi ketidakpastian cuaca ekstrem, sekaligus mendorong perlunya pengembangan variabel tambahan untuk memperkuat pemodelan perilaku distribusi.
