Hasan, Samsurijal, Novita Sari, Efti, Aryadi, Aris Suhud
Abstract: This training is based on the results of the analysis of the situation of blacksmiths (Rumbio Jaya Steel) Teratak Village, Rumbio Jaya District has not been professional in using social media to improve marketing performance.… ance. The target group in this service amounted to 150 people, namely the number of members of the Rumbio Jaya Steel cooperative. While the strategic targets in organizing this activity are 30 young men and women consisting of 18 young men and 12 young women who are sons and daughters of Rumbio Jaya Steel Cooperative Members. The implementation of this community service is carried out with steps: (1) Identification of potential; This activity is carried out in a participatory manner between the team and the target group aims to identify all the potential possessed by the target area; (2) Identification of opportunities based on the strength of the resources owned based on the results of identifying potential; (3) Determining the most popular platform; (4) Determining training needs; (5) Developing a training schedule; (6) Organizing training; and (7) Practice/simulation. activities carried out at the ONGA MAN Furniture Business Place in Ridan Permai Village, Bangkinang Kota District. As well as monitoring citizen responses through like, comment and share for 1 (one) week. The conclusion shows the low utilization of social media to promote products produced by furniture service businesses. In time, the production of these MSMEs can enter the popular Marketplace in Indonesia so that the volume of sales of marketing performance increases and the marketing reach is wider.

Analisis Palung Pendingin Kaeltroog Dan Jenis Material Pipa Pendingin Pabrik Gula PT. Sinergi Gula Nusantara Di Unit PG. Djombang Baru

Idhofi Rahmad Aryan
Abstract: Analisis efisiensi palung pendingin (Kaeltroog) dilakukan pada Palung D yang terdiri dari tujuh unit kaeltroog. Setiap kaeltroog memiliki kapasitas maksimum antara 200 hingga 290 hektoliter, yang bervariasi tergantung pada… da jumlah massecuite yang dihasilkan dari alat pan masakan. Kaeltroog berfungsi sebagai tempat palung pendingin dari messecuite yang baru keluar dari pan masak an, setelah di kaeltroog selanjuttnya di kirimkan ke ke Mono Vertical Cristalizer membutuhkan waktu sekitar 30 menit, di dalam Mono Vertical Crystalizer ini sebagai untuk proses pendinginan lebih lanjut  Dalam kaeltroog, terdapat sistem pengaduk yang berperan penting dalam mencegah pengentalan massa dan mempercepat penurunan suhu, sehingga massa dapat mencapai suhu yang diinginkan dengan lebih efisien. Data rinci menunjukkan bahwa semua kaeltroog di Palung D diisi dengan kurang-kurangnya 180 hektoliter, meskipun perkiraan waktu untuk proses pendinginan adalah 24 jam dan tidak menuntaskan. Desain kaeltroog mencakup beberapa komponen penting, seperti bak pendingin, pengaduk, as pengaduk, roda gigi, motor listrik, dan talang penghubung antar palung. Penggunaan material pada pipa stainless steel tipe 316, karena memiliki ketahanan yang sangat baik terhadap korosi, terutama di lingkungan yang mengandung klorida, yang sering ditemukan dalam proses pengolahan gula.  Penelitian ini memberikan wawasan mengenai efisiensi operasional palung pendingin dan pentingnya desain yang tepat untuk meningkatkan proses pendinginan dalam industri pengolahan massecuite.

Finite Element Method for Stress Analysis of an Infinite Plate with an Elliptical Hole Using Functionally Graded Materials

Nguyen, Dien
Abstract: This study investigates the stress concentration factor in an infinite steel plate with a thickness of 1 cm, containing an elliptical hole, subjected to biaxial loading at infinity. The elliptical hole has semi-axes a=5.0 cma… 0 cma = 5.0 \, \text{cm}a = 5.0 cm (major axis) and b=2.5 cmb = 2.5 \, \text{cm}b = 2.5 cm (minor axis). The applied stresses at infinity are a tensile stress of σ1=100 kg/cm2\sigma_1 = 100 \, \text{kg/cm}^2= 100 kg/parallel to the major axis and a compressive stress of σ2=−100 kg/cm2\sigma_2 = -100 \, \text{kg/cm}^2= -100 kg/ perpendicular to the major axis. The material properties include Young's modulus E=2.1×106 kg/cm2E = 2.1 \times 10^6 \, \text{kg/cm}^2E = 2,1.  kg/ and Poisson's ratioν=0.3\nu = 0.3  = 0.3. Using analytical solutions from classical elasticity theory, the maximum tangential stress at the edge of the ellipse is calculated as σmax=600 kg/cm2\sigma_{\text{max}} = 600 \, \text{kg/cm}^2= -600 kg/, yielding a stress concentration factor of kσ=σmax/σ=6k_\sigma = \sigma_{\text{max}} / \sigma = 6 =  =6. Additionally, a finite element (FE) analysis based on the Salerno and Sahoni problem for a quarter section of the plate results in kσ=3.1125k_\sigma = 3.1125 = 3.1125 for a configuration with s/r=5s/r = 5s/r = 5, showing a discrepancy of 1.3% compared to the theoretical value of kσ=3.1k_\sigma = 3.1= 3.1 from Peterson's Stress Concentration Factors. The results demonstrate good agreement between the calculated model and theoretical predictions, validating the accuracy of the FE approach for stress concentration analysis in such configurations.
