Introduction
Education is a tool to produce qualified human resources. The Indonesian government is trying to improve the quality of education based on national education goals. The Law No. 20/2003 states that, the contents of the objectives of national education are to improve the quality of education in each type and level of education and to develop capabilities and shape the time and civilization of a dignified nation in order to educate the life of the nation. Therefore, the implementation of education must run effectively so that the aim of education is achieved.
Currently, the industrial revolution 4.0 is also known as an era of disruptive innovation, where innovation is developing very rapidly. The more significant challenges will be faced, including in the field of education so that education is demanded to change immediately. Changes in education today must be related to the industrial revolution 4.0 so it is called education 4.0. Education 4.0 is an education characterized by the use of digital technology in the learning process [1]. This system will ease the learning process continuously without the boundaries of space and time.
Therefore, the current learning process must be adapted to the 4.0 revolution era to improve or increase the quality of learning that takes place by enriching learning resources and media such as textbooks, modules, transparency overhead, film, video, television, slides, hypertext, and web [2]. One of them is by developing learning media which is a significant source to support the learning process. In the process of learning the subject of land resource evaluation, the use of instructional media is very much needed. This is because this course covers the concepts of land use and evaluates their use. For this reason, this subject need innovative learning media following the era of education 4.0.
Based on interviews with geography students who took a course in evaluating land resources, several obstacles that disturbed the learning process were found. The reason is that students are still confused to understand the material so that it makes students less enthusiastic in the learning process. In the ongoing learning process, they are still using Microsoft PowerPoint software. The contents of Microsoft PowerPoint are in the form of writings on material related to land use including dry land. This proves that the use of technology in education is still low compared to other fields such as industry, agriculture, communication [3]. So, most students want innovative and exciting learning media in explaining the contents of the material. The media itself is an inseparable part of the teaching and learning process in implementing teaching and functions to make teaching more interesting so that it can foster motivation to learn, clarify the meaning of material in students' environments to achieve teaching objectives [4][5][6].
Innovative learning media following the era of education 4.0 to overcome problems in the learning process in this land resource evaluation course. To overcome this problem, three-dimensional learning media related to dry land use material is needed. Simple three-dimensional media has several advantages, namely providing hands-on experience, presenting concretely and avoiding verbalism, can show the whole object both construction and how it works, can show the flow of a process clearly. But this three-dimensional media also has some weaknesses that are not able to reach targets in large numbers; storage requires ample space [7].
This three-dimensional media in the form of 3D maps for the use of dry land which can concretize abstract concepts so that they can later be easily understood. The 3D dry land map uses an application in which this media uses the use of computerized technology that is overgrowing in an era like now [8]. This is very supportive of the current conditions in which technology is developing rapidly in the industrial revolution era 4.0.
The application used in making this 3D dry land map in QGIS (Quantum GIS). This 3D map is also based use image of the aerial. The aerial image has the potential for more detail than satellite imagery [9]. 3D maps their dry land is based on aerial imagery using QGIS will make students quickly understand the material with 3D vis-ualization. This is because the information provided can show the real state and detail of the map that is drawn. Students are also able to concretize land use without the need for actual fieldwork.

Method
This research is development research, which later will produce specific products. The product produced in this study is a 3D map of aerobic dry land based on the Quantum GIS application.
The research development model uses the Sugiyono model with the following stages of the model: This development research only carried out until the fourth stage, namely product validation. The third stage in the form of product design will produce a 3D dry land media map.
They continued in the fourth stage in the form of design validation. This stage is the last in this study. At this stage, the product form of media 3D map of dry land validated by experts such as media specialists and subject matter experts. Media and material experts will assess the product produced using the instruments provided. The instrument used by experts in the form of a questionnaire with a Likert scale containing the quality of learning media and the content of the material. The score guidelines at the validation stage by media and material experts [11] are as follows in table 1. The results of the validation calculated percentage calculation done by comparing the scores obtained with the maximum overall total, as follows in formula 1: (1)

Result and Discussion
The implementation of this research passed several main stages, they were, (1) the development phase consists of product design, product design validation, and (2) the evaluation phase consists of a revision of the design, product testing, product revision, utility testing, product revision, and final mass production products. However, this research only reached the development stage, namely, product validation.

3.1
Preliminary study stage 1) Identification of problems: Problems obtained when data collection by observation. The problem has been described in the background so that the development of 3D dry land maps media is needed to support learning in this 4.0 education era. 3D maps of dry land can clearly explain the form of dry land use and its distribution. 2) Data collection: Collecting data obtained from observational studies that have conducted by interviewing some unfortunate geography student state university. Also, literature studies are critical to support the contents of the 3D dry land media.

Media development stage
This stage consists of 2 stages, namely product design and product validation.

Stage of 3D map media design:
The design of the 3D map media design has limitations that are: 1) The 3D map only displays the use of dry land and its distribution, 2) The making of this 3D map is intended for teaching media for the subject of land resource evaluation in the geography or related majors.
The design of the 3D dry land map media uses some data, namely Bondowoso Regency land map, Wringin District administration map, DEM imagery, and aerial imagery. This data was obtained from Digital Ina-Geoportal, ASTER DEMNAS USGS Earth Explorer, and Balitbang of Bondowoso Regency. These data will be processed using the Quantum GIS (QGIS) application. Processing to produce 3D maps of dry land is passed through several stages, which are explained as follows in fig.2.

Based on the plot of making 3D maps of dry land above, it can be seen that aerial image data used to determine the type of land use in the area. When aerial imagery data in the form of land use then added to DEM data, the land produces more information related to contours and slopes. Other data such as land type data and regional administration are also needed so that the land in the area is more detailed in the information produced.
The results of processing from aerial imagery with the application of QGIS obtained the pattern of dry land use and its use from the land itself (fig 3).

For the first stage, the 3D map presents the distribution of dry land in the Wringin District, Bondowoso Regency, represented by four villages (fig 4-6). The four villages are Jatisari, Sumbermalang, Jambewungu, and Wringin Villages. The distribution of dry land dominates the area in Wringin District. This supported by the fact that land use in the Wringin District is in the form of 3601.93 Ha of dry land [3] Topography of Wringin District is mainly in the form of mountains and hills with a slope of 3-15% and 16-40%.  Based on the four 3D maps of dry land available (fig 3-6), it can be seen in detail how the topography, slope, and shape of dry land use in the Wringin District area of Bondowoso Regency. On the 3D map of dry land in each village were given information on the type of land. This is very important later in order to be able to manage and utilize land according to the type and nature of the existing land so that it can be optimally cultivated.

Design validation: Design validation is a process for assessing product design carried out by experts who are experienced with the product design. It aims to make the strengths and weaknesses of the design of products discovered [4]. The product design validation will be carried out by material experts and media experts. Material validator is a person who is an expert on material about the use of dry land. For this reason, the material validator is Sadewa Purba Sejati, lecturer in physical geography in the Department of Geography, Universitas Amikom Yogyakarta. Media experts who act as validators are instructors of instructional media about dry land use. The media validators is Kunthum Ria Anggraheny, a lecturer of Geography Education study program at Universitas Widya Dharma, Klaten. The writing font on the map is still unclear The font of the writing on the 3D map will be corrected and clarified More information displayed Show more information on a 3D dry land map The results of the validation conducted by two validators on aerial imagery based 3D dry land maps with the QGIS application are valid for the materials, methods, and media. The media validator gave the score of 86 and the score of 81from material expert. From two validators evaluations, a score above 80 was categorized and declared valid. However, the validator still provides suggestions for improvement so that the 3D map media is better, as follows in table 2.
Suggestions given by media experts and material experts are beneficial for improving the 3D dry land media map. For the evaluation phase in this research, the development will be continued based on the results of this study. The development of in-structional media in the subject of land resource evaluation will not be separated from multimedia. Especially now, an era where technology is developing very rapidly called the 4.0 era. For this reason, education nowadays must be able to develop media by utilizing computerized technology [14] that is interactive and innovative in the learning process so that it is easier for the students to understand the material described in the educational era 4.0 [15].

Conclusion
The development of innovative media in the era of education 4.0 is now required in the learning process. One of the developments of innovative media in the field of land resource evaluation is aerial image of based 3D maps with QGIS applications. With this 3D map, students can directly concretize what is in their minds. Students will not be confused imagining how dry land forms and their direct use. When there is practicum in the field, students already understand what they explain. The design of the 3D dry land map was validated by two experts in the field of material and media. The results of these two experts are above 80. This shows that the 3D map media is feasible to enter the next stage of product trials.
