Abstract

Population growth increases every year, especially in Serang Regency, causing traffic problems including accidents, congestion, or being faced with conditions of frequent road scrambling. In preliminary observations, this happened to the Unsignalized Three Way Petir Intersection . This research was conducted to determine the existing performance of the intersection and find alternative solutions to overcome the problem situation and find out the cost needs needed in planning the proposal. Thus, of course, data is needed to be able to analyze it.  The method used is based on the Indonesian Road Capacity Manual (MKJI) of 1997, the required data consists of primary data by conducting a field survey, to find out the volume of vehicles (Average daily traffic / ADT for seven days from 06.00 to 18.00 WIB, road geometrics, traffic conditions, and environmental conditions. It is known that the Unsignalized Three Way Petir Intersection type is type 322, meaning 3 arms 2 lanes 2 directions, the data uses the form USIG I and the form USIG II from MKJI 1997. The results showed that the existing performance at the Unsignalized Three Way Petir Intersection showed the largest total traffic flow value of 3,480 passenger car unit (pcu) / hour, the saturation degree (DS) value was 1,026, which means, the traffic flow has exceeded the road capacity, with an intersection traffic delay of 16,426 sec / pcu, a delay in main road traffic (B-D) of 7.4584 sec / pcu and a delay in minor road traffic (C) of 38.2352 sec / pcu,  queue odds are between 42.3554% to 84%.  Alternative solutions that can be done prohibit the right turn traffic from minor roads, as well as widening on the main road from 3 m per lane to 3.5 m so that the short width of each lane = 3.5 m and the shoulder width of 0.5 m, in total to 8 m, so that the cost required in the planning is Rp. 2,220,051,000 (two billion two hundred twenty million fifty-one thousand rupiah).

Abstract

This paper presents the results of research on the design of geopolymer concrete mixes. The main objective of this research is to develop an efficient and easy design of low-alkaline activator geopolymer concrete mixture, which until now has been the biggest obstacle in the use of geopolymer concrete. The variables reviewed were the amount of alkaline activator was quite low at 4%, room temperature and 60oC ratio of alkaline activator/fly ash (AAS/FA) were 0.35, 0.4, 0.5, 0.6. The test results show the parameters of geopolymer concrete with low alkali activator 4%, sodium silicate/sodium hydroxide ratio 2.5%, sodium hydroxide molarity 14M, type F fly ash and the discovery of the relationship model of compressive strength and the ratio of alkali activator/fly ash with a very high correlation as basic development of geopolymer concrete mix design. The design of the geopolymer concrete mix developed is easy because it is application-based and efficient because it only requires 4% alkaline activator.

Abstract

Bogor Regency is a buffer zone for the city of Jakarta. Bogor Regency is directly adjacent to the north with DKI Jakarta and Bekasi City and Depok City. The two cities are satellite cities directly adjacent to Jakarta. In 2017 and 2018, the addition of roads in Indonesia was only less than 0.1% -0.2%/year, while the growth of motorized vehicles was more than 10%/year. This is very disproportionate to the addition of roads in our country. Based on the study above, research on motorized vehicles was carried out in front of the Nurul Hidayah Mosque, which is located on Jl. Salabenda-Semplak, Bogor Regency. The density of motorcycles, private cars, public transport cars and freight cars has a significant effect on noise. From all analysis calculations, the largest equation is obtained on the third day of the second point of the study SLM2, with a contribution of 22.12%. The following calculation is obtained, y = 54.01 + 0.04x1 + 0.32x2 – 0.22x3 + 0.12x4. This means that if there is no decrease in the density of motorbikes, the noise level in SLM2 is 54.021 dBA. The density of motorbikes, private cars, public transport cars and freight cars also has a significant effect on noise, the second largest equation is obtained on the fourth day of research at the third point with a contribution of 21.24%. The calculation of the equation below is obtained, y = 55.02 + 0.03x1 – 0.07x2 + 0.02x3 – 0.01x4. The meaning of the above equation is that if there is an increase in the density of motorcycles and public transport cars, the noise in SLM3 is 55,021 dBA.

Abstract

The Osing is one of the tribes in Banyuwangi, with nomadic life history. Since the conditions change after the war against the invaders, this tribe has lived permanently. One of which is in Kemiren Village. Owing to maintaining its cultural heritage, Kemiren Village was established as a tourism village in 1996. Through this establishment, the society uses the existing spaces around the village as a space for community activities to socialize and do tourism activities. The study aims to evaluate spatial flexibility in Kemiren Village as an implementation of a sustainable tourism village's concept. An ethnographic strategy was approached from a macro perspective to see the impact of changes in social conditions on the use of the existing space in the village, particularly the village's streets. The study results revealed that the Osing in Kemiren Tourism Village had developed its tourism potential by utilizing village streets as a space for social activities and tourism attractions. According to spatial flexibility principles, four types of flexibility happened on these streets in Kemiren Village, such as adaptable, universal, movable, and responsive flexibility.

Abstract

One of the less well-organized residential areas in Buleleng is the Kampung Bugis settlement. The development of the Bugis Village settlement as one of the densest settlements in Buleleng does not get good regulation and control so that the village environment tends to be slum, disorganized, uncomfortable and unhealthy. The existence of Bugis Village which is increasingly dense by residents also has an impact on the density of buildings in residential areas. Unfortunately, this condition is not balanced with the arrangement and sufficient land area. Due to the high environmental pressure, residents become spatially motivated by creating "new spaces” to meet their individual needs. This is very interesting to examine so that in the future it can be used as a reference for the development of residential areas in the future. Territoriality characteristics that occur in Bugis Village are as follows, land ownership status does not really affect the formation of territorial boundaries, boundary elements are not always a marker of social identity, space that has the highest privacy always has firm territorial boundaries, space resulting from territorial expansion tends to use semi-fixed elements as a territorial marker. This happens because there is still awareness from the residents of the settlements that the expanded land is legally not their property. The territoriality formed in settlements is generally to fulfill six main needs/activities, namely: drying, gathering/playing, trading, storing goods, parking and socializing. Apart from being a territorial marker, some of the boundary elements are an embodiment of aesthetic needs.

Abstract

Tenjolaya Subdistrict, Tamansari Subdistrict, and Ciomas Subdistrict of Bogor District has an area of 61.74 km2, divided into 25 villages, and 1 urban-village with those total populations density are 4,819.7 people/km2. The increasing population and significant development in the region has increased the movement of traffic flows to and from the region, which is expected to cause some particular problems in traffic congestion on Road segments. This research aims to make the model of the trip generation and the trip attraction caused by land use such as education area, medical, office, lodging, physical fitness center and tourism in the three sub-districts. MKJI 2017 is used as a data processing guideline for the method of calculation of transport analysis. Then use Trip Generation Manual and modelled into SATURN software. Total trip generations from 3 sub-districts of the study area are 4,403.78 trips/hour, and with total trip attractions are 6,165.33 SMP/hour. The design of the transportation modelling equation for Ciomas subdistrict, Tamansari District, and Tenjolaya subdistrict is 21,230 – 0,950 (X). The Model of trip generation and trip attraction has a value of R2 = 0,9687. The level of service is obtained index in the range of A until D, with an average is B, indicating a relatively stable condition. although in some areas, it is still necessary to repair and improve road network infrastructure, and strive for a comfortable and efficient alternative public transport system (time, cost, energy) to transfer people from private vehicles to Public transport.

Abstract

Pura Mertasari is a temple located on Jalan Kepundung, Denpasar-Bali. The spatial concept of this temple is tri mandala, with the main zone functioning as the offal, the middle zone functioning as the middle jaba and the nista zone functioning as the jaba sisi. However, in addition to the macro spatial division, the uniqueness of the micro spatial division of the jeroan pura was found. The spatial division in the jeroan of this temple is called the architectural concept of bale meten. The bale meten architectural concept is a unique concept. However, a problem was found, namely there has been no similar research that examines this concept. Thus, departing from the aim of enriching scientific studies of Balinese architecture which is applied to the spatial of temples and the desire to study the architectural concept of bale meten on the spatial of temple innards scientifically, this research needs to be carried out. So that in the future this research can be used as reading material and knowledge about the application of the architectural concept of bale meten in the spatial of temple innards. This research method is descriptive qualitative with a case study approach. The result of the research is that the innards of the temple are manifested like the concept of the bale meten space. This finding is confirmed by the division of three elements of the spatial hierarchy, namely the main function as gedong in the bale meten and as a spatial pelinggih on the innards of the temple, madya as the terrace of the owner of the house in the bale meten and as the canopy of pelinggih / place to put ceremonial facilities on the innards of the temple, and nista as the visitor's terrace in the bale meten and as a place for pengempon in the jeroan of pura.

Abstract

Every building renovation or building reconstruction often occurs demolition of the wall. The demolition of this wall becomes construction waste therefore it is necessary to experiment with using wall waste to become a productive material. This research is an experiment in making concrete using wall waste. The wall waste used is in the form of rubble from the ruins of a red brick wall. The compression test method refers to the 1974:2011 SNI regulations on concrete. In this test, the focus is on the maximum compressive strength of concrete that can be produced in the sample. Each sample of the test object is divided into three groups, each group has three test objects. The first group is a sample of pure concrete, fine aggregate 100% concrete sand. The second group is a fine aggregate experimental concrete sample containing 25% wall waste, and the third group contains 50% wall waste. The test object is in the form of a concrete cylinder with a diameter of 150 mm and a height of 300 mm. Concrete testing is carried out at the age of 7 days, 14 days, and 28 days. The results of this study provide information that red brick wall waste can be recycled into concrete material so that it does not become construction waste. It is known that the compressive strength of concrete using additional wall waste as fine aggregate meets the requirements of structural concrete quality and can improve the quality of concrete. Furthermore, it is hoped that the wall waste can be reused as an added material to the concrete mixture in building construction activities or other construction using concrete.
