The Impact of Viral Stealth Marketing on Consumers' Buying Interest on Cosmetic Products

Andi Dian Sry Rezki — Fri, 20 Sep 2024 23:23:30 +0000

The concept of viral stealth marketing has been actively used by marketers to make products well received in society. Stealth marketing is one of the digital marketing strategies that advertises a product or service to someone, without them realizing that they are becoming a marketing object. Stealth Marketing is more commonly found on social media platforms today such as Facebook or Instagram compared to traditional advertising media such as newspaper, TV and radio broadcasts. Influencer as a service provider is becoming more general in this method of marketing. Cosmetic products are products that are often marketed with the viral stealth marketing method. Recommendations of cosmetic products from people we know will be easier to accept. Data collection was carried out by conducting a survey on the age group of Gen Z. Data processing using paired t-test and F-test. The results of the paired t-test found that there was a difference in the buying interest of consumers who received product promotion treatment (B1) with the group of consumers who received agent recognition treatment (B2) with a significance value of 0.000. Meanwhile, the results of the F-test show that the presence of agent recognition treatment affects consumers' buying interest in indicators of seeking information, trying products, knowing more, and the desire to own products. This result indicates a change in the buying interest of consumers to cosmetic products when they are aware of the use of viral stealth marketing promotion methods.

UTILIZATION OF SPACE FUNCTION IN FLOOF PRONE AREAS ON THE BANKS OF THE SADDANG RIVER AND MATA ALLO RIVER IN ENREKANG DISTRIC

Enrekang District is one of the flood-affected Districts in Enrekang Regency. Enrekang District is traversed by 2 major rivers, namely saddang river and mata allo river. The Mata Allo River is one of the watersheds in Enrekang Regency, while the Sadang River is a watershed of North Toraja Regency and Enrekang Regency. The main cause of flooding is due to the overflow of the Saddang River and the Mata Allo River with the characteristics of a fairly fast water flow. The main point of flooding is at the confluence of the two rivers. That's why the area is particularly prone to flash flooding. The utilization of the function of space on the river bank should consider the distance of the flood protection boundary. The distance of the river border must be taken into account properly, so that the misappropriation of the function of space on the border or floodbank of the designation of cultivated areas (settlements or other public facilities) can be avoided. This research uses a naturalistic paradigm with the research method used is a qualitative method with an evaluative descriptive approach. This study observes the natural / existing conditions of space function utilization on the banks of the Saddang River and Mata Allo River which will then be evaluative approached based on the literature review that has been collected. The findings related to the use of space functions include, among others, there is a discrepancy in the river border distance rules in the Enrekang Regency RTRW and the use of floodbanks as housing / settlements. Based on flood calculations, the plan is to obtain a safe distance from the river border as far as 45 meters from the banks of the Saddang River and the Mata Allo River.

SOCIALIZATION AND PLANNING OF TPS 3R DESIGN CONCEPT SUSTAINABLE IN SALEMO ISLAND COASTAL SETTLEMENTS

The rapid development and population growth in coastal areas have caused the carrying capacity of the environment to decline. This problem is caused by several factors, one of which has become a common problem in coastal settlement areas, especially in coastal settlements of small islands, is the problem of waste. The waste problem that occurs is due to several factors, such as limited access and land to be used as a landfill, poor waste management, inadequate waste facilities and infrastructure and lack of public awareness to maintain the cleanliness of the environment. Public awareness to maintain the cleanliness of their environment needs to be educated by the application of 3R waste management (reduce, reuse and recycle) from the source while maintaining nature and the environment in a settlement. The availability of appropriate waste facilities can also help waste management in small island coastal settlements. The existence of the 3R TPS will be very helpful in waste management in the settlement, both organic and inorganic waste. The location to be studied is the coastal settlement of Salemo Island. The existing state of the waste system in the coastal settlements of Salemo Island does not have a TPS or access to the nearest landfill, so people throw their garbage directly into the sea or are left to accumulate on the shores of their beaches. This situation is very concerning because there is no solution from the local government to overcome this problem. With this research, it is hoped that it can provide solutions and inputs in planning the right waste processing using the reference to the 3R TPS design concept produced in the coastal settlements of Salemo Island.

more destructive than constructive. The Complex of Makassar Metro Square Shophouses is considered one of the largest shophouse complexes built by developers in Makassar City. This study aims to evaluate the performance of the Makassar Metro Square Shophouse Complex based on the level of occupant satisfaction. This study used a survey method, where the data collection techniques were field observation and questionnaires distributed to 60 residents who were chosen through accidental sampling. Data were then analyzed using descriptive and regression techniques using Microsoft Excel and SPSS 25 applications. The results show that the occupant satisfaction index was at the level of 64.5% and on the interval scale it was at the level of fairly satisfied. The testing of physical attribute variables of the Shophouse Complex (X1) and the supporting facilities of the residential unit (X2) on occupant satisfaction (Y), concludes that the two variables have a significant positive effect. Factors that affect occupant satisfaction can be seen in the quality of the initial design, material quality, occupant characteristics, occupant adaptation, and external factors.

Effect of Post Weld Heat Treatment (PWHT) on Mechanical Properties, Chemical Composition, and Microstructure on Carbon Steel Pipe SA-106 B with SMAW-GTAW Welding Combination

Welding is one of the company's success factors in connecting high-pressure pipes to welding technology implementation projects. The PLTU (Power Plant) construction project carries out the welding process in every construction activity that involves welding experts and various other disciplines. This research uses an experimental method with PWHT temperature variable on mechanical characteristics, microstructure, and chemical composition. The material used is SA-106 B carbon steel pipe with a 6G welding position. Welding is carried out using a combination of SMAW welding with E9016-G electrodes, and GTAW welding with ER90S electrodes. The higher the PWHT temperature, the tensile strength, hardness, and chemical composition of the carbon content and microstructure of the pearlite phase (dark etching) will decrease. Meanwhile, the impact energy will increase and the ferrite phase will experience growth in the ferrite grain structure (bright etching).
