The island of Bali, not only presents the beauty of natural panoramas but also presents new experiences and knowledge about infrastructure and the concept of residential areas. It should be acknowledged that the factors of Hindu customs and religion as the majority have a strong influence, so the existence is well-maintained and sustainable. One of them can be found in Penglipuran Village.

Penglipuran village in the Bangli regency is located in the central part of the island of Bali with the area of 112 hectares covering 50 hectares of agricultural area, 45 hectares of bamboo forest, 9 hectares of settlements, 4 hectares of customary area, and the rest for public facilities. Geographically, Penglipuran village is located 600 meters above sea level which makes the temperature of this village tend to be cool with maintained vegetation. This village has been designated as a tourism village, that’s why the residents work in tourism and merchandise vendors, apart from being farmers, employees, craftsmen, and civil servants.

The philosophy of settlement development refers to Tri Hita Karana, which recognizes the existence of three areas, namely Parahyangan, Pawongan, and Palemahan. Parahyangan is a harmonious relationship between humans and God (sang Hyang Widi) placing the temple building as a place of worship in a high position, as a form of respect to the relationship between humans and God. On the north side, there are temples for worship, including Penataran Temple, Puseh Temple, and Pura Dalem. Pawongan is a harmonious relationship between humans because humans will live side by side and cannot live alone. Houses in Penglipuran Village are connected by special gates so that residents can easily communicate and have cooperation in village activities to maintain a sense of kinship and belonging to each other, including welcoming tourists who come to visit. Palemahan means a harmonious relationship between humans and their natural environment, so that nature and ecosystems are well preserved. It is manifested by maintaining the authenticity of the architecture of the houses and yards, cooperation agreements to clean the environment, spatial planning, and the main route in the middle of the village should not be passed by motorized vehicles to free from pollution, including the conservation of bamboo forests as rainwater catchment areas for springs. Another unique feature is an open space to meet each other in the form of a 'rurung gede' road that climbs higher to the north, and every house has a gate facing this road.

The challenges of modernity have also penetrated the Penglipuran Village area so that part of the construction uses modern building materials, but specifically for the pawon and bale adat, they still use traditional building materials, namely bamboo shingle roofs. The community gradually has an open perspective and when they become a Tourism Village, they are ready to interact with tourists from all over. Things that need to be considered are the area's carrying capacity because the presence of tourists has the consequence of increasing water demand, waste, and transportation burden in the area.

The authentic findings in Penglipuran Village provide insight into the spatial layout of the settlement which can be developed as an integrated area with philosophical content, functions, and balance of human life besides having the potential as a tourist resort. ***

Infrastructure development is quite intensive in Indonesia in order to ensure the availability of infrastructure facilities, both physical and non-physical, for the people’s daily needs, either the economic or social spheres. The scope of infrastructure includes roads, transportation services, water, waste management, outdoor sports buildings and other facilities, energy production and distribution, while the non-physical includes various efforts made to support public infrastructure facilities needed by the people.

Observing infrastructure facilities is an activity for students and Stube HEMAT Yogyakarta team in the Resilient Infrastructure: Providing A Safe and Comfortable Life. Activities are designed in a study visit to the island of Bali as a world-level magnet (June 26-29 2023). Several elements of the infrastructure can be observed from traveling via the toll road of Solo to Probolinggo, which can be reached in 6-7 hours, then the Coal Power Plant in Paiton, Probolinggo which supplies Java and Bali's electricity needs. The journey to the east ends at Ketapang port, Banyuwangi Regency which is very strategic as a link to the island of Bali. The port has three types of piers, namely Landing Craft Machine (LCM), Moveable Bridge (MB), and Pontoon to facilitate the movement of vehicles and ferries. However, at certain times there is a long queue of vehicles.

Buildings in Bali have distinctive architecture, such as the temple at Tanah Lot on a coral island, which will appear to float during high tide. Ulun Daun Temple in Bedugul looks to be floating in Lake Beratan. It is no less interesting to observe the Pura Dalem Agung Padangtegal in the forest area of the Sacred Mandala Wenara Wana with monkey primates that walk freely, followed by a settlement with a spatial layout in Penglipuran Village, Bangli regency which applies traditional Balinese architecture. The loyalty of the local village community in upholding ancestral customs both in rituals and daily life and the agreement to keep the area orderly and in harmony with nature is the key to the sustainability of Penglipuran village.

The Bali Mandara toll road, which is the pride of the island because it was built over the sea for more than 12 kms, took the students and the Stube HEMAT Yogyakarta team to the southern Bali area, to be precise, the Karst hill area which was developed into the Garuda Wisnu Kencana (GWK) Cultural Park area. Inside is Plaza Wisnu, Plaza Garuda where an 18-meter-tall statue of Garuda's head is placed. Plaza Garuda is the central open space of Lotus Pond which is surrounded by halls and karst stone pillars. Various major national and international events have been held here. The development of the GWK area is an alternative to utilize marginal land without destroying it but providing economic benefits for the region and the community. In South Bali, apart from GWK, the marginal Nusa Dua area has already been developed into a leading tourist area by involving local culture and harmony with the environment.

It is an irony when infrastructure facilities are built and decorated, but the telephone network 'disturbs' the atmosphere when telephone poles and cables are set in a location. In addition, the road load in Bali will get heavier due to the crowdy traffic. What will Bali look like in the future, weather it will remain a sustainable tourist magnet or it will stagnate or even decline? Don't let time answer it, but precautionary steps need to be taken. ***

Resilient Infrastructure Exposure

Talking about Magelang, it must be identical with Borobudur and Mendut temple, but there is also a new tourist attraction, namely Rhema Hill, a hill for sightseeing and praying. This hill is located in the hamlet of Gombong, Kurahan, Kembanglimus, Magelang, about 11 minutes or 4.8 kms drive from Borobudur Temple. On top of this hill, there is a unique building in the form of a crowned dove. However, this building is more famous by the name of the chicken church.

Rhema Hill is a place for Stube HEMAT Yogyakarta students to learn the program of the Resilient Infrastructure: Presenting a Safer and More Comfortable Life, enriching students' insights about unique and inspiring architecture (Saturday, 3/06/2023). In this place, students observed the building of a prayer house on Rhema hill which makes visitors curious and brings benefits to the surrounding community. Labeled with Architectural Tour, this activity was attended by students with various study backgrounds such as management, accounting, electrical engineering, nursing, and also pastoral theology.

The students learned the guide's presentation telling that the construction began when Daniel Alamsyah prayed all night on this hill, and he was much encouraged when he met Jito, a disability child. In 1992, he started to build this place but it stopped due to the 1996 monetary crisis. The building was neglected, but began to be more attractive again when it became the shooting location of the movie "Ada Apa Dengan Cinta 2". Since then, tourists began to visit this place, and subsequently famous for the chicken church.

During the visit, the Stube HEMAT students observed the shape of the building consisting of seven floors, starting from the first floor to the top of the pigeon crown. The location of the building is on a hill by climbing stairs as high as approximately 150 meters. The tour guide accompanies to walk surround the inside of the pigeon church building. On the 1st floor, there are paintings and the history how to build it, along with prayer rooms for every religion. Going up to the 2nd floor, this room is to be used as a worship place for Christians but now it is no longer used. On the 3rd floor, paintings of diversity of faith up to the 4th floor are presented. On the 5th floor, visitors can enjoy paintings in the form of mountains in Java along with buildings from all over the world. In addition, there is a view of several mountains around it. The 6th floor is the head and beak constructed in an open state so that visitors can look to the East and it is a waiting room before climbing to the crown. Limited space on the 7th floor is a nice time for visitors to be able to see around 360 degrees, observing the hills including Borobudur temple. The pigeontail section is a café where visitors can enjoy fried cassava and other menus managed by the local community.

Through the Architectural Tour, students find new enlightenment, not only about buildings and constructions but also the hiding idealism to present unique and useful building architecture works. The pigeon church can be a tourist destination, as well as a provider of employment and culinary business.

The existence of Rhema Hill infrastructure is very useful as it is functional and unique,  that local community also enjoy the benefits of economy increase finally. ***
