Abstract

This study aims to analyze and formulate an effective promotion mix strategy to increase sales in Abg Rafin Catering's Micro, Small, and Medium Enterprises (UMKM) located in Percut Sei Tuan. Abg Raffin Catering has been operating for several years and has a loyal customer base. As UMKM operates in the culinary sector, Katering Abg Rafin faces the challenge of increasing market share and revenue amidst tight competition. And in recent years, sales growth has stagnated. One factor contributing to this problem is the lack of optimality in the promotion strategy used. Many UMKMs, including Abg Rafin's Catering, tend to rely on traditional promotion methods, which are now becoming less competitive with digital marketing techniques and more modern promotion approaches. To achieve that goal, a proper promotion mix strategy is essential. We use qualitative research with case study methods. Data is collected through in-depth interviews with business owners, customer surveys, as well as analysis of sales and promotional documents. The results show that an optimal combination of the components of the promotion mix—advertising, direct marketing, personal selling, sales promotion, and publicity—can significantly increase sales. In particular, the increased use of social media and digital platforms as a means of promotion has had the greatest impact. Based on the findings, it is recommended that Katering Abg Rafin implement an integrated and sustainable promotion mix strategy, focusing on enhanced digital marketing activities and direct interaction with customers. This approach is expected to help Katering Abg Rafin compete more effectively in the market and sustain sales growth.

Abstract

Limited land and high land prices in areas designated for commercial activities in the city center have resulted in the invasion of commercial functions into residential areas, one of which is the area around housing in Cibodas Baru Village. The aim of this study is to identify the factors that cause changes in residential land use to trade and commercial services in Cibodas Baru Village Housing, Cibodas District, Tangerang City. The trade and services population is 621 using the Slovin formula sampling method. The analysis method used is descriptive quantitative and superimpose (overlay), based on drone observations of existing land use in 2021 with the suitability of the Tangerang City Regional Spatial Plan for 2012-2032, there is a difference between housing and trade and services of 56,919.33 m2 (5 .65 Ha) or 9.27%. The trend of land change from 1998 to 2023 means the change per year is 0.44% per year. Analysis of factors changing residential land use to trade and services in Cibodas Baru Housing using SPSS software by entering several variables, the variable is the degree of land accessibility with a significant relationship accepted with an Asymptotic Significance (2-sided) value of 0.000004 < 0.05 then there is a strong relationship with chi-square = 21.190, therefore the higher the land accessibility, the higher the change in the function of residential land use.
Free solvent isolation of Fe3O4 from magnetic material iron sand utilizing high-energy ball milling as adsorben remazol turquoise blue G-133 and remazol red RB-133 Ramadhan, Muhammad; Fahmiati, Fahmiati; Alrum, Armid; La Ode Muhammad Zuhdi, Mulkiyan

Abstract

The extraction of Fe3O4 from iron sand frequently utilizes a highly concentrated HCl solution, which is hazardous to the environment. The high-energy ball milling method of separating Fe3O4 from iron sand might produce Fe3O4 without acids and maintains its magnetic characteristics with a yield of 81.87%. The FTIR results suggest that the Fe3O4 separation procedure with high-energy ball milling was effective in eliminating the silica pick after activation with 2 M NaOH, which was confirmed by SEM-EDS data indicating there was no silica on the material's surface. Fe3O4 was separated, allowing use as an adsorbent to treat textile industry waste such as Remazol Turquoise Blue G-133 and Remazol Red RB-133. The adsorption of Fe3O4 on these two dyes occurred at pH 5, and as adsorbate concentration, contact time, and adsorption temperature of Fe3O4 were raised, the adsorption capacity increased. Remazol Turquoise Blue G-133 and Remazol Red RB-133 have qmax values of 16.75 and 1.43 mg/g, respectively. The isothermal adsorption of Fe3O4 for the two dyes quite follows the Freundlich isothermal with KF values of 1.87 and 0.42 L/g and n values of 2.17 and 1.22, respectively, results suggest that the adsorption process occurs physically and forms a multilayer adsorption surface. These results are supported by data obtained from the adsorption kinetics, which shows that it follows the first-order adsorption kinetics. The dyes thermodynamics also showed positive results for ΔHo and ΔGo, indicating that the process of adsorption was endothermic and not spontaneous, but to the degree of disorder (ΔSo), Remazol Turquoise Blue G-133 outperformed Remazol Red RB-133.
