Abstract

ABSTRACT The purpose of this study is to examine the interactions between kascing fertilizers and mutiara NPK 16:16:16 on the growth and production of okra and shallots in the intercropping system. This research used a completely randomized factorial design, consisting of two factors. The first factor was the application of vermicompost (K), consisting of 4 levels, namely 0, 750, 1500 and 2250 g/plot and the second factor was NPK 16:16: 16 (N), consisting of 4 levels, namely 0, 15, 30 and 45 g/plot, so that obtained 16 treatment combinations with 3 replications and 48 experimental units. Each unit consisted of 4 plants per plot and 2 plants are samples, so that the plant had 192 plants for okra plants and 5 plots for shallots and 2 plants was become samples with total plants of 240. Based on research results indicated that intercropping system on okra plants and shallots resulted smaller plant growth and production compared to monocultures. The interaction of kascing fertilizer and NPK 16:16:16 fertilizer had no significant on all observed parameters. The main effect of the dose of kascing fertilizer was a significance on all observed parameters. The best treatment was significant on a dose of kascing fertilizer of 2250 g/plot. The main effect of the 16:16:16 NPK dose was significant on all observed parameters. The best treatment was found on NPK 16:16:16 with dose of 45 g/plot.

Abstract

The use of public networks such as free Wi-Fi is increasingly widespread along with the development of information technology. However, public networks have a high level of vulnerability to security threats such as data interception attacks in the center, and session hijacking. This study aims to examine the role of Virtual Private Network (VPN) in maintaining user privacy when accessing public networks. The method used is a literature study with a descriptive qualitative approach, based on academic literature, research reports, and the latest technical documentation. The results of the study show that VPN is able to encrypt data traffic, hide the user's IP address, and prevent unauthorized access to sensitive information. Analysis of VPN protocols such as WireGuard, OpenVPN, and L2TP/IPSec indicates that performance and level of protection vary, with WireGuard showing the highest efficiency. Although effective, the use of VPN also has limitations such as decreased connection speed and privacy risks if using untrusted services. Therefore, choosing the right VPN service and implementing good security policies are very important in efforts to protect digital privacy. This study confirms that VPN is an important component in the cybersecurity ecosystem, especially in the context of public network access.
