With the development of technology, the thinking to use applications in the business world also develops. One of them is a business in the field of transportation. At present an application-based transport service has emerged. The emergence of these services, the Conventional Taxis have new competitors. The existence of such competition has led to disputes between conventional taxis and application-based taxis. The existence of Application-Based Taxi, causing some people in the city of Mataram have the opportunity to switch interests using Application-Based Taxi. Under these conditions, the number of fleets and the suitability of conventional taxi rates in the city of Mataram need to be reviewed. In this study, examined taxi rates according to the calculation of vehicle operating costs. Then compared with the ability to pay and the will of the people of the City of Mataram. Then the number of taxi fleet requirements for the City of Mataram will be calculated. From the results of this study it can be concluded that: 1). there is an excess number of taxi fleets, which is 550 fleet optically, but in reality the current taxi fleet operating based on real conditions in the field is as many as 636 fleets from all operators, 2). 48.75% of respondents have the ability to pay a tariff of Rp.3,900 / kilometer and the remaining 52.25% of respondents are forced to use conventional taxis, 3). Current rates are in accordance with government regulations. This can be seen from the calculation of vehicle operating costs (BOK) for the tariff per kilometer is Rp. 4,000 per kilometer while the current tariff is Rp. 3,900, - only a difference of Rp. 100

The geopolymer introduced by Davidovits is a new binder for making concrete as an alternative to ordinary Portland cement. One of the materials used to make geopolymers is fly ash. The annual worldwide production of fly ash is estimated to be around 500 Mt. In making geopolymers with fly ash, scientists usually use activators such as silicate and aluminate solutions, as well as with kaolinite. The geopolymerization process is related to the metal oxide ratio of the activator solution. Geopolymers can withstand temperatures up to about 600°C, so they are fire/heat resistant. This paper describes the role of the comparison of dominant elements in a mixture of geopolymer paste with fly ash and alkali which produces the best quality based on compressive strength, where there is an effect of the ratio of alkali on the compressive strength of geopolymer paste. Almost all of the highest compressive strength obtained did not follow the Davidovits rule. This is caused by other factors that affect the compressive strength such as the content of elements such as Si and Al in fly ash and the curing temperature. However, the volumetric and mechanical properties of the artificial aggregate (geopolymer fly ash application) meet the requirements as a road material. It's just that the absorption value is above the requirements (>3%). Seeing the properties of these geopolymers, there is hope to be developed into materials for building materials. Geopolimer yang diperkenalkan oleh Davidovits adalah pengikat baru untuk membuat beton sebagai alternatif pengganti semen Portland biasa. Salah satu bahan yang digunakan untuk membuat geopolimer adalah fly ash. Produksi tahunan fly ash seluruh dunia diperkirakan sekitar 500 Mt. Dalam membuat Geopolimer dari fly ash para ilmuwan biasanya menggunakan aktivator seperti larutan silikat dan aluminat, serta dari kaolinit. Proses geopolimerisasi berkaitan dengan rasio oksida logam dari larutan aktivator. Geopolimer dapat menahan suhu hingga sekitar 600°C, sehingga tahan api/panas. Makalah ini menjelaskan tentang peranan perbandingan unsur-unsur dominan pada campuran pasta geopolimer dengan fly ash dan alkali yang menghasilkan kualitas terbaik berdasarkan kuat tekan, dimana terdapat pengaruh perbandingan alkali terhadap kuat tekan pasta geopolimer. Hampir seluruh kuat tekan tertinggi yang didapatkan tidak mengikuti aturan Davidovits. Hal ini disebabkan oleh faktor lain yang mempengaruhi kuat tekan seperti kandungan unsur-unsur seperti Si dan Al dalam fly ash dan temperatur curing. Namun, properties volumetric dan mekanik agregat buatan (aplikasi geopolymer fly ash) memenuhi persayaratan sebagai bahan jalan. Hanya saja nilai penyerapannya di atas persyaratan (>3%). Melihat sifat-sifat geopolimer tersebut, membuka harapan untuk dikembangkan menjadi material untuk bahan bangunan.

Food is the most important basic need to sustain the life of all creatures, including humans. So it is necessary to strive for adequate and equitable fulfillment of needs. In addition to survival, food is very influential in improving the quality of life of the nation. Planting various vegetables for food availability in the household does not have to be supported by a large yard. The yard with a limited area can also be used as land for growing vegetables and fruits. The implementation of these activities sequentially consists of socialization, discussion, direct practice and mentoring. The results achieved from this program are increasing community awareness and skills through activities carried out with the community around Barejulat Village so as to encourage the community to be motivated to optimize the potential of resources in the form of yards owned by the community to increase. Welfare based on technology and local wisdom. At the same time, it teaches the community to understand how important it is to cultivate a passion for farming from an early age so that in the future the sustainable food house program can be continued by future generations.

On several roads in the city of Mataram, such as the Dr. Wahidin road, there are many shops that do not have enough parking space, so many vehicles are parked on the shoulder of the road and even on the road. The presence of pedestrians crossing the road and the activity of vehicles entering/exiting the road affect the speed of traffic, and the capacity of the road so that at certain hours there are frequent traffic jams. This of course will have an impact on the delay at the intersection of Dr. Wahidin. As for the Caturwarga street, there are schools, hospitals and shops that do not have sufficient parking space, many vehicles that drop off and pick up passengers and vehicles that enter and leave the land use side of the road. Of course, this condition affects the smooth flow of traffic, so it has an impact on delays at the Catur Warga intersection. This study analyzes side resistance, capacity and delay at unsignalized intersections on Caturwarga and Dr. Wahidin roads. The total of this side resistance will be used to analyze how much influence it has on the delay using the 1997 MKJI method. The results of the analysis at the Catur Warga intersection have side friction, and the delays are 790.7 events/hour, 16.63 seconds/smp. Meanwhile, at the Dr. Wahidin intersection, the side friction and delays are 403.1 events/hour and 17.00 seconds/pcu, respectively. From the results of regression analysis, side barriers affect traffic delays by 89.7% and at Dr. Wahidin intersections by 79.7%. Partially at the Catur Warga intersection, the side friction variable that has the most influence on delays is Exit/Entrance Vehicles on the land use side of the road (EEV). On the Dr. Wahidin road, the side obstacle variable that has the most influence on delays is Pedestrians (PED).

Street Catur Warga and Dr. Wahidin did not have enough stops, so many vehicles stopped on the shoulder of the road and parked on the side of the road. The number of people crossing the road and the number of vehicles entering/exiting the road causes a reduction in the speed, volume and capacity of the road so that at certain hours traffic jams often occur. This study analyzed the side friction, volume and speed of Catur Warga and Jalan Dr. Wahidin used the 1997 MKJI method. The results of the analysis on one-way roads, especially the Catur Warga road, had side friction, volume and speed respectively, namely 790.7 events/hour, 1533.75 smp/am and 46.08 km/hour. While the two-way street, Jalan Dr. Wahidin, has side friction, volume and speed of 403.1 events/hour, 1916.15 smp/hour and 38.58 km/hour. From the results of the regression analysis, side friction is very influential on the volume and speed of traffic. This can be seen from (r) in the range of 0.7 < r < 0.9 where the number shows a strong influence and 0.9 < r < 1 indicates a very strong influence. The results of partial regression analysis show that on the Catur Warga road, the side barriers that have the most influence on volume are Parking and Vehicle Stops (PSV), while at speed, namely Vehicles Exiting/Entering Roadside Land Use (EEV). On the Dr. Wahidin the side friction variable that has the most influence on volume is Pedestrians (PED), while at speed, namely Parking and Vehicle Stops (PSV).

In the mixing process between asphalt and aggregate, absorption of asphalt by the aggregate occurs through the pores of the aggregate. The volume of asphalt not absorbed by the aggregate can be defined as effective asphalt content which determines the percentage of airspaces in the compacted mix. The proportion of voids formed in the mixture contributes to the durability of the mixture against temperature and climate conditions. This study aims to examine the effect of effective asphalt content and the asphalt film thickness on the voids proportion in asphalt mixture. Based on the analysis, it can be concluded that the particle size distribution of the aggregate affects the total surface area of the aggregate in the mixture and the pores of the aggregate affect the effective percent of asphalt content. Aggregate with a small grain size produced a larger total surface area of aggregate. Meanwhile the use of aggregate with small pores produced a higher effective percent of asphalt content. The higher the effective asphalt content and the asphalt film thickness, the larger the voids in mineral aggregate and the voids filled with bitumen. In contrast, the voids in the mixture decreases with increase the effective asphalt content and the asphalt film thickness. In all the voids proportions analyzed, the effective asphalt content and the asphalt film thickness have a very significant effect.
