This study is motivated by the declining revenue of Kaliwungu Printing every month, which is caused by the inconsistency in product promotion. As a result, the lack of regular and comprehensive promotional efforts has led to limited public awareness of Kaliwungu Printing. The purpose of this research is to develop a structured and comprehensive promotional tool to showcase the products offered by Kaliwungu Printing.
This research employs a qualitative method to obtain accurate and relevant data. Data collection techniques include observation, interviews, and questionnaires. The respondents consist of media experts, content experts, and a group of five employees from Kaliwungu Printing. The validity of the data is measured using the rating scale method proposed by Sugiyono. The results of the study show a score of 30 from media experts, 36 from content experts, and an 84% validity rate from the group assessment. Based on the overall evaluation indicators, these results fall into the "very good" category. Thus, the study concludes that the proposed promotional tool is suitable for implementation and can be utilized effectively

Peningkatan mobilitas kendaraan di perkotaan seringkali mengakibatkan kesulitan dalam mencari lokasi parkir yang tersedia. PT. ARISA MANDIRI PRATAMA (ARISA) sebagai sebuah perusahaan dengan jumlah karyawan yang besar, menghadapi tantangan serupa di mana karyawan mereka harus menghabiskan banyak waktu untuk mencari lokasi parkir yang masih kosong, yang pada akhirnya dapat mengganggu produktivitas dan kenyamanan kerja. Oleh karena itu, tugas akhir ini bertujuan untuk merancang, mengembangkan, dan mengimplementasikan alat informasi slot parkir otomatis menggunakan Arduino Uno dan sensor inframerah guna mengatasi masalah tersebut. Alat ini akan memanfaatkan teknologi sensor inframerah untuk mendeteksi ketersediaan slot parkir secara real-time. Sensor Inframerah akan ditempatkan pada pintu masuk dan pintu keluar yang akan mengirimkan informasi ke Arduino Uno ketika kendaraan memasuki atau meninggalkan slot tersebut. Informasi ini akan ditampilkan pada layar LCD, dengan bantuan alat ini, karyawan dapat dengan mudah mengetahui slot parkir yang masih kosong, menghindari pemborosan waktu, dan meningkatkan efisiensi dalam mencari lokasi parkir.

Water is very important for all aspects of life on earth, agriculture is one of the fields that really need large amounts of water because of the use of water in the
process of plant photosynthesis. Water that has good quality is if the water is not excessively polluted by harmful chemicals or minerals. One indicator that water is polluted is a change in temperature and pH (acidity) of the water. Temperatures that are too hot in the water will interfere with the growth of plants and other microorganisms. While the normal pH of water has a pH that ranges from 6.5 to 7.5. The quality of water and soil is very important in agriculture. The level of acidity (pH) and soil temperature are one of the things that affect plant fertility. Therefore, the quality of water and soil on agricultural land is one of the important things that needs special attention in its management. One solution so that water and soil quality can be monitored and managed efficiently is to utilize a Wireless Sensor Network based on the Internet of Things (IoT). The use of the ESP8266 Module as a WIFI module, is widely used by Internet of Things-based applications because the price is cheap so it reduces a lot of costs and has a fairly good speed of 80 MHz. This study aims to develop the concept of a Wireless Sensor Network by utilizing the ESP8266 module to monitor pH values using a pH Meter Analog Kit sensor and temperature from agricultural land using a DS18B20 Waterproof sensor and can be monitored at any time using a smartphone.

Developing of prototype now are became easier with the existence  of 3 d printer, now is common known as rapid prototyping method. There are many different method on 3d printing depend on material used for printing. The wide range of material that can be print using 3d printer such as metal to plastic even ceramic. The rapid prototyping using 3d printer have various advantage compare to traditional prototyping. The development of 3d printing makes it not only for prototyping but can be a small batch manufacture, where economic scale of production cannot be reach with traditional production. The fast development of computer and internet technology have big impact on the 3d printer development, before the development of reprap 3d printing was only knew by industrialist and manufacturer. After reprap born, 3d printer is became more common to personal user. People can have their 3d printer at home. People can design their own product using CAD software and send it to 3d printer, or send it via internet to print by 3d printing company. Even there ara lot of advantages of 3D printer development , there is some disadvantages of 3d printer, especially on regulation.        
 

SMK Negeri 11 Semarang is a school that has four competency skills, namely Graphic Preparation, Graphic Production, Multimedia, and Animation. Every time they enter the beginning of the school year, school socialization and skills competencies are carried out to new students through the Student Orientation Period, using the lecture method from each of the Head of Skills Competencies. Researchers have created an attractive and informative audio-visual presentation media, packed with docudrama stories, namely documentary films. The results of validation tests conducted by expert experts and users show that the documentary films that have been developed by researchers fall into the very good criteria with a percentage of 93.75%. In addition, through the use of the 228 new students as respondents, it can be concluded that the documentary film developed by the author falls into the good criteria with a percentage of 61%.
