Abstract

A test bar is a tool that represents an axis whose position will be tested relative to other machine elements as well as the movement of the axis relative to its own position. With a test bar as a precision tool, the deviation value of a machine's geometry can be determined. In the initial stages of making the spindle test bar, namely determining the design according to ISO 230-1:1996 standards, machine testing tools books and directly observing the Aciera F3 Milling Machine. The stages of making a test bar spindle consist of several machining processes such as the lathe process, heat treatment and grinding process, quality checking, and testing. The results of the quality check showed that there were 4 actual dimensions within the tolerance limits and 3 other actual dimensions had sizes outside the tolerance limits, but sizes outside these limits had no effect on the function of the workpiece being made, so this calibration tool could still be used. For testing the spindle test bar on the Aciera F3 Milling Machine object, there were deviations in eccentricity and parallelism with the transverse direction table of 0.030 mm and 0.011 mm, respectively.

Abstract

Silase ialah pengawetan pakan hijauan melalui fermentasi anaerob. Dedak fermentasi dapat digunakan sebagai aditif untuk mempercepat proses fermentasi pembuatan silase. Penelitian ini bertujuan untuk mengetahui pengaruh lama fermentasi pada penggunaan dedak fermentasi terhadap kandungan bahan kering dan bahan organik silase tebon jagung. Penelitian dilaksanakan di peternakan Cowla Farm, Dusun Gembor, Desa Cikembulan, Kecamatan Sidamulih, Kabupaten Pangandaran dan analisis laboratorium dilaksanakan di Laboratorium Nutrisi Ternak Ruminansia dan Kimia Makanan Ternak Fakultas Peternakan Universitas Padjadjaran Jatinangor pada tanggal 3 Februari 2021 – 19 Maret 2021. Penelitian menggunakan metode eksperimental dengan Rancangan acak lengkap (RAL) dengan 3 perlakuan dan 7 ulangan. Perlakuan terdiri atas P1 (Lama Fermentasi 7 hari), P2 (Lama Fermentasi 14 hari), P3 (Lama Fermentasi 21 hari). Data penelitian dianalisis menggunakan Analisis Ragam. Hasil analisis menujukan bahwa perlakuan berpengaruh tidak nyata terhadap kandungan bahan kering dan bahan organik silase tebon jagung.

Abstract

The widespread expansion of digitalization has driven Micro, Small, and Medium Enterprise (MSME) owners in Sawarna Village to utilize various digital platforms for communication, marketing, and sales transactions. However, the high adoption rate of digital services is not matched by adequate understanding of account security, making MSME owners one of the most vulnerable groups to threats such as phishing, account hijacking, data misuse, and online fraud. Through the Community Service Program (KKN), this training activity was conducted to enhance awareness and capability of MSME owners in securing the digital accounts they use to support their business activities. The training encompassed socialization sessions, technical assistance, and basic audits of participants' account security settings. The results demonstrated an improvement in MSME owners' understanding of digital security risks as well as behavioral changes, particularly in the adoption of stronger passwords, activation of two-factor authentication, and configuration of account privacy settings. This program proves that KKN-based digital security training is effective in increasing awareness and digital account protection capabilities among MSME owners, thereby supporting the sustainability of their businesses in a more secure manner.
