ABSTRAKDesa Bonjeruk adalah sebagai Desa Wisata Budaya dengan bekal kesejarahannya. Selain memilikitempat yang bersejarah, wisata desa Bonjeruk juga mengusung konsep ecotourism yang menawarkankeaslian kehidupan desa lengkap dengan penghidupan masyarakatnya sebagai petani. Namun petanisetempat belum memiliki pengetahuan untuk mengelola sampah pertaniannya. Salah satu teknikmemanfaatkan limbah menjadi pupuk adalah menjadikannya sebagai pupuk kompos untuk menekanpemakaian pupuk anorganik yang dalam jangka panjang residu dan limbahnya dapat merusaklingkungan sekaligus menyelesaikan permasalahan sampah. Kegiatan dilaksanakan dalam bentukpenyuluhan, pelatihan dan pendampingan. Penyuluhan dimaksudkan untuk berbagi pengetahuan tentangisu lingkungan terkait masalah sampah sekaligus ajakan untuk berperan aktif dalam gerakanpenyelamatan lingkungan. Kegiatan penyuluhan diperkuat dengan pemberian pelatihan tentang caramengolah sampah organik menjadi pupuk kompos. Selain pelatihan pembuatan kompos, kegiatan jugaditujukan untuk menginisiasi pembentukan bank sampah masyarakat desa Bonjeruk sebagai upayarintisan menuju desa Proklim, sebuah program peningkatan kapasitas masyarakat untuk mitigasi danadaptasi terhadap perubahan iklim dari Kementerian Lingkungan Hidup dan Kehutanan. Kegiatan initelah terlaksana dan mendapat sambutan antusias dari warga. Kini warga makin menyadari nilaiekonomis dari sampah yang mereka hasilkan dengan mampu membuat sendiri pupuk kompos darilimbah organik.

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.

The problem found is the high price of raw materials and homestay furniture. It's hard to get quality wood planks at low prices. On the other hand, public knowledge is still limited in finding products as substitute materials at low prices. So construction tends to use materials of poor quality, the important thing is that the price is affordable. So the life of buildings and furniture becomes shorter and is not good from an aesthetic point of view. Based on these problems, a solution is sought that refers to the priorities that have been set, namely the innovation of cheap panel/board products by utilizing waste (fly ash). The method adopted is to provide training to builders on how to make panels from geopolymer fly ash. Thus, the purpose of the community service program carried out by the LPPM Unram Community Service Team is to provide skills to carpenters in making boards/panels from geopolymer fly ash. The method used is to provide training. The training emphasizes the ability to hone participants' skills in choosing materials, mixing materials according to composition, and printing geopolymer paste into panels (boards). The training covers work procedures and stages of technology application. At the end of each activity, an evaluation is carried out so that it can be seen what the achievements and shortcomings are. Activities range from socialization, training preparation, and training implementation to implementation evaluation. As a result, after attending the training, the participants were able to make geopolymer panels (boards) made from fly ash and alkaline. add insight and knowledge and skills. This can be seen from the ability of the training participants (builders and hotel managers) based on the materials and examples provided during the training.

If the population increases and the total traffic flow also increases without being matched by an adequate increase and improvement of road infrastructure, it will result in an increase in the degree of saturation which is a parameter in determining the performance of a road section. One of the roads affected by the population growth is the Saleh Sungkar road which is an urban road type 2/2 UD. The Greenshield, Greenberg and Underwood models are the 3 models used to determine the relationship between volume (flow), speed (speed) and density (density). The relationship between flow, speed and density is used to determine or determine the mathematical value of the capacity of a road section and the degree of saturation. This study aims to determine the comparison of the degree of saturation of Jalan Saleh Sungkar which is an urban road using the Greenshield, Greenberg and Underwood models against MKJI 1997. From the results of the analysis, it was obtained that the degree of saturation using the Indonesian Road Capacity Manual (MKJI 1997) was 0.53, so Jalan Saleh Sungkar was at the level of sevice "C" (stable flow, but the speed and motion of the vehicle were controlled, the driver was limited in choosing the speed). Meanwhile, the degree of saturation based on the Greenshield model is 0.55, the Greenberg model is 0.72 and the Underwoods model is 0.60. Both MKJI 1997 and the three models are still at level of service "C".

Transportation in general has a major influence on individuals, society, economic development, and socio-politics of a region. Operational aspects must be planned properly so that online motorcycle taxi services and conventional motorcycle taxis can carry out their functions as Modern City Transportation economically, efficiently and effectively. In this post-pandemic period, we know that there are differences in the characteristics of online motorcycle taxis and conventional motorcycle taxis in providing services to their users.By conducting survey research based on the level of explanation is descriptive research, to obtain characteristic data the researcher has distributed questionnaires to 400 respondents who are online motorcycle taxi users and 400 respondents who are conventional motorcycle taxi users. The two characteristics turned out to be quite similar to each other. The total population of motorcycle taxi users is 486,715 (Mataram City in figures, 2019). By using the formula for calculating the number of samples from Slovin (Statistical Formula, 2012) and a 95% confidence level, the total sample size is 400 respondents.The results of the synthesis of these two characteristics can be conveyed as follows: Gender of users is dominated by women as much as 58.8%, the purpose of the trip is dominated by work and shopping trips 51.87%, the mode before switching is dominated by motorcycle modes as much as 59.5%, connecting trips The distance to the base is dominated by a distance of 0-1 km, the connecting trip from the stop to the destination is dominated by a distance of 0-1 km using walking mode

The unsignalized four-way intersection in Kediri is located in the Kediri Subdistrict of West Lombok Regency and is one of the unsignalized intersections situated very close to the center of community activities. Additionally, there is an educational center in the vicinity, and the traffic conditions at this intersection are quite congested on a daily basis. The mobility level of both individuals and goods, using both light and heavy vehicles, is visibly high at this intersection. A median strip is the central part of the road that physically separates opposing traffic flows. Therefore, the use of a median strip on the road significantly impacts traffic flow efficiency, by reducing delays, queue probabilities, side hindrances, decreasing accident rates, and providing comfort for road users, thereby making road users feel safe and organized. Thus, the government is planning to construct a road median.This study analyzes the performance of an unsignalized intersection before and after the installation of a median, covering aspects such as volume, side constraints, queue probabilities, delays, and saturation levels, using the 1997 Indonesian Highway Capacity Manual (MKJI) methodology.The analysis results for the unsignalized intersection before median installation show a capacity of 3061.5 vehicles per hour, a saturation level of 0.970 (Service Level D), a delay of 14.885 seconds per vehicle, a queue probability of 36.361%, and side constraints amounting to 881.9 incidents per hour. On the other hand, for the unsignalized intersection tipe after median installation, it exhibits a capacity of 3330.5 vehicles per hour, a saturation level of 0.729 (Service Level C), a delay of 12.654 seconds per vehicle, a queue probability of 21.942%, and side constraints amounting to 629.2 incidents per hour.The performance of the four-way intersection in Kediri on TGH Ibrahim Kholidi Road, in the Kediri Subdistrict of West Lombok Regency, was lower before the median installation compared to the tipe of intersection after median installation.

Salah satu permasalahan dalam transportasi adalah kecelakaan lalu lintas. Salah satu penyebabnya adalah ketidak-tertiban dari sikap pengendara sepeda motor di ruas jalan karena akan mengganggu kendaraan lain berpotensi untuk menyebabkan kejadian kecelakaan dan pelanggaran lalulintas meningkat dari tahun ke tahun. Pengendara motor di Kota Mataram dari sejak usia dini sampai mampu mengendarai kendaraan bermotor belum memiliki pemahaman yang baik tentang tata cara berlalulintas yang tertib di jalan raya serta berkeselamatan yang tinggi. Pembelajaran pengenalan perangkat keselamatan berlalulintas dijalan raya sejak usia dini adalah suatu bagian yang cukup penting dilakukan, sehingga pada saat mereka dewasa dan sebagai pengendara atau pengguna sepeda motor sudah memiliki pemahaman berkeselamatan dan kemampuan pengendalian kendaraan secara lebih baik. Metode pemberian pembelajaran atau penyuluhan tentang pengenalan fasilitas keselamatan berlalulintas di jalan raya dan tata cara berlalulintas dijalan, melalui cara bermain sambil belajar, tentu adalah metode efektif dalam penyampaian target capaian yang diharapkan. Namun karena masih usia dini, ada sedikit kesulitkan dalam menarik fokus perhatian mereka yang lebih lama. Metode seperti ini untuk anak usia dini harus terus-menerus disampaikan secara berkesinambungan agar potensi pelanggaran dalam berkendaraan dijalan raya yang berdampak pada kecelakaan saat mereka dewasa dapat diminimalisir, sehingga secara tidak langsung terciptanya tertib berlalulintas di wilayah Kota Mataram dapat lebih terwujud.
