This study is aimed to reveal the improvement in the competency of productive teachers of both state and private vocational high schools in Sleman Regency after participating in a self-development program in terms of psychological maturity and socio-cultural aspects. This study was carried out in two state vocational high schools SMKN 1 Sedayu and SMKN 1 Seyegan, and one private vocational high school SMK Muhammadiyah Pakem. It was a qualitative study in nature using interview and documentation as the means of collecting the data. Fifteen productive teachers of the three vocational high schools with expertise in Building Engineering Drawing (BED) were purposively selected to be the research subjects. The obtained data in the form of interview tapescripts, photos, and documents were triangulated to ensure data validity. The data were then analyzed systematically through three main stages including open coding, axial coding, and selective coding. The results show that through self-development, the BED productive teachers in state vocational high schools can improve their pedagogical and professional competencies. In addition, this program also develops their knowledge and skills in the areas of curriculum, expertise, technology, as well as teaching strategies and methods. Even so, in the case of BED productive teachers in private vocational high schools, this self-development program does not significantly improve their competencies.

The objectives of this research were: (1) producing Android-based AR products in the form of a Wood Field Laboratory Work module in Department of Civil and Planning Engineering Education, Faculty of Engineering UNY to facilitate students’ visualization abilities; (2) knowing the quality of Augmented Reality products for the Wood Field Laboratory Work module so that it is suitable for use by students and teaching staff; and (3) addressing the learning problems that have so far been present in the Wood Field Laboratory Work. The method used was the Software Development Life Cycle software development model which was described by the v-model waterfall. The v-model included: (1) the stage of specification of user requirements; (2) system architecture design; (3) designing components; (4) writing program codes; and (5) testing. The test results using ISO 25010 indicated that the application of learning media was stated to be very feasible in functional suitability, compability, and usability aspects. While from the performance efficiency aspect, the application was considered feasible because there was no memory leak on the device that run it, and CPU usage by five different devices reaches 10%, which is still below the safe limit (15%).

To improve the quality of infrastructure that is durable and solid, innovation needed to make sure the high quality ofroads. This study aimed at knowing the effect of PET addition in the percentage of 0%, 1%, 1.5%, and 2% for asphalt concrete-binder course on Marshall characteristics, and revealing whether the results of Marshall testing with added PET material and carbide waste filler has fulfilled the general specification of Directorate General of Highway 2010. This study used PET plastic addition with variations of 0%, 1%, 1.5% and 2%. Each variation of PET content was made on 3 samples for objects testing to obtain values of density, VIM, VMA, VFA, stability, flow, and MQ. The results of this study indicated that the addition of PET plastic content and carbide waste filler affects the value of the asphalt characteristic of Marshall. The most effective addition was at 1% level with a density of 2.23 gr/cc, VIM value of 4.82%, VMA value of 14.58%, VFA value of 67.18%, flow value of 3.30 mm, stability value of 3060.42 kg and MQ value of 936.79 kg/mm. Overall, the addition of PET plastic and carbide waste filler to the characteristics of the marshall.

Today, there is an urgent need in our country to develop and implement new energy - and resource-saving technologies for wastewater treatment and water treatment. The need for such a system is determined by the urgency of the tasks of protecting the health of the population, agricultural products, and other biological objects. Wastewater is contaminated with radioactive substances, heavy metal ions, toxic substances, and pathogenic microbes. During the work, wastewater contaminated with heavy metal ions Cd2+, Pb2+ was treated with a natural zeolite material. The mechanism of water purification from metal ions is based on the porous structure and adsorption capacity of zeolite. Heavy metal ions diffuse into the pores of the zeolite material, displacing sodium ions, which are structural modifiers. The zeolite treatment process was carried out by measuring the permeability of wastewater using a conductometer and comparing its results with the value of the permeability of distilled water. According to the results obtained, this method can be used to completely purify wastewater from heavy metal ions.

The purpose of this research is to know the effect of beach sand as a substitute for river sand in a mixture of concrete asphalt against the characteristic values of the marshall and to determine the effect of adding sugarcane ash filler with the percentage of ash filler 0%, 5%, 10%, 15% on the concrete asphalt mixture against the characteristic values of the marshall. This research is an experimental study using fillers in the form of sugarcane ash filler with varying levels of variation in the amount of 0%, 5%, 10%, 15%. The specimens using AC-BC mixture was then tested using the Marshall method values of stability, density, flow, VIM, VMA, VFA, MQ. The results of this study indicate that the addition of sugarcane ash filler and the use of beach sand as a substitute for river sand affect the value of the characteristics of the marshall. The more filler levels used in the asphalt mixture, the greater the value of stability and MQ. While the flow value, density, VIM, VMA, VFA are getting smaller. Other factors that influence marshall characteristic values are asphalt content used, aggregate gradation, temperature in compaction, mix quality, and the process of mixing asphalt.

This study aims to: 1) determine the zoning for pedestrian ways; 2) determine the type of pedestrian ways in UNY; 3) to identify problems and solutions related to pedestrian ways in UNY. The method used in this research is descriptive with quantitative approach, by comparing the standard criteria for open space with the condition of reality. The technique of collecting data through observation and measurement of the dimensions of buildings and open spaces using the assistance planimeter website. Basic physical reviews grouping zones through which the road that separates the faculty contained in UNY. The results showed that: 1) zoning is physically in the Campus UNY consists of six zones, namely: Zone A (FT, LPPMP, LPPM), Zone B (FE, FIS, Dean Faculty, Kopma, PPs Lama, FIP), zone C (FBS, Science Faculty, Masjid Mujahideen), zone D (GOR UNY and vicinity), zone E (Stadiums, Tennis Court, FIK), and zone F (Rector, New PPs); 2) in real terms, there are four types of pedestrian ways in UNY, namely: Type 1 (separated), Type 2 (integration), Type 3 (dominant car), and Type 4 (corridor); 3) alternative solutions for problems of special dimensions and availability (level of service) the dimensions sidewalk pavement is in zone B is not ideal, while the sidewalks in zone A is sufficient available. Keywords: Pedestrian, Sidewalk, Yogyakarta State University. ABSTRAKKajian ini bertujuan untuk: 1) mengetahui pembagian zona untuk pedestrian ways; 2) mengetahui tipe pedestrian ways di UNY; 3) mengetahui permasalahan dan solusi yang berhubungan dengan pedestrian ways di UNY. Metode yang digunakan dalam kajian ini adalah deskriptif melalui pendekatan kuantitatif, dengan cara membandingkan kriteria standar ruang terbuka dengan kondisi realita. Teknik pengumpulan data melalui observasi dan pengukuran dimensi bangunan serta ruang terbuka menggunakan bantuan website planimeter. Dasar pengelompokkan zona melalui tinjauan fisik yaitu jalan yang memisahkan beberapa Fakultas yang terdapat di UNY. Hasil kajian menunjukkan bahwa: 1) pembagian zona secara fisik di kawasan Kampus UNY terdiri dari 6 zona, yaitu: Zona A (FT, LPPMP, LPPM), Zona B (FE, FIS, Dekanat FMIPA, Kopma, PPs Lama, FIP), Zona C (FBS, FMIPA, Masjid Mujahiddin), Zona D (GOR UNY dan sekitarnya), Zona E (Stadion, Lapangan Tenis, FIK), dan Zona F (Rektorat, PPs Baru); 2) secara riil, ada 4 tipe pedestrian ways di UNY, yaitu: Tipe 1 (separated), Tipe 2 (integration), Tipe 3 (car dominant), dan Tipe 4 (corridor); 3) alternatif solusi atas permasalahan khusus dimensi dan ketersediaan (tingkat pelayanan) trotoar yaitu dimensi trotoar yang berada di zona B belum ideal, sedangkan trotoar pada zona A sudah cukup tersedia.
