Abstract

Truck mounted crane is a tool used to move objects from one place to another within a limited operating range with the advantage of heavy load mobilization and cargo carrying capacity in one vehicle unit. The crane on the truck is equipped with long arms that can be extended or shortened automatically to adjust to needs, and can adjust the height by changing the elevation angle. This study examines the analysis of the strength of the crane boom in two scenarios of 8.178 meters and 5.478m using the finite element method. In each test scenario, four variations of elevation angles were carried out, namely, 90°, 100°, 110°, and 120°, and carried three variations of loads, namely, 2 tons, 2.5 tons, and 3 tons. In the first scenario with a length of 8.178 meters, the largest deformation was obtained when loading 3 tons and an elevation angle of 90°, the largest von misses value was obtained when loading 3 tons and an angle of 120°, and the largest safety factor was obtained when loading 2 tons and an angle of 90°. Meanwhile, in the second scenario with a crane boom length of 5.478 meters, the largest deformation was obtained when loading 3 tons and an angle of 90°, the largest von misses value was obtained when loading 3 tons and an angle of 120°, and the largest safety factor was obtained when loading 2 tons and an angle of 90°.

Abstract

Perusahaan-perusahaan yang terdaftar di Bursa Efek Indonesia (BEI) dalam industri logistik pascawabah COVID-19 akan menjadi target penelitian ini, yang berupaya menganalisis pengaruh profitabilitas, leverage, dan kebijakan dividen terhadap nilai perusahaan. Data yang digunakan dalam penelitian kuantitatif ini berasal dari sumber sekunder, yaitu laporan tahunan Bursa Efek Indonesia (BEI). Setelah uji asumsi tradisional selesai, data yang diperoleh kemudian dianalisis dengan regresi berganda, yang kemudian dilanjutkan dengan mengevaluasi koefisien determinasi (R2), kelayakan model (uji F), dan hipotesis (uji t). Nilai perusahaan dipengaruhi secara signifikan oleh kebijakan dividen dan kemungkinan, sementara leverage memiliki pengaruh yang kecil, menurut penelitian ini. Dimasa depan Perusahaan logistik sebaiknya fokus pada meningkatkan profitabilitas dengan memperbaiki efisiensi operasional, menggunakan hutang dengan sebaik-baiknya serta lebih memperhatikan dengan kebijakan dividen dan mengkomunikasikannya dengan para pemegang saham perusahaan.

Abstract

In Tanjung Tembaga, Mayangan District, Probolinggo City, this study examines traditional fishermen's interest in adopting floating net cage (FNC) technology for marine aquaculture and how their knowledge, economic conditions, and social factors influence it. Data were obtained from 130 respondents selected purposively. The data were analyzed using multiple linear regression with SPSS version 27, following the quantitative descriptive technique established in the Ecosystem Approach to Fisheries Management (EAFM). Although economic factors did not have a positive and significant effect on interest in FNC adoption, knowledge and social conditions did (t = 3.853; Sig. = 0.000 and t = 3.351; Sig. = 0.001). The R² value of 0.357 proves that these three factors influence the interest variable by 35.7%. The results of this study indicate that interest prior to adoption is more influenced by understanding of fishing regulations, high-value species, community dynamics, and local knowledge than by financial status or asset ownership. To help traditional fishermen transition to sustainable marine aquaculture, this study recommends focusing less on financial assistance and more on enhancing technical knowledge, community engagement, and conflict management.
