Abstract

Road intersections are places where traffic conflicts occur. The volume of traffic that the road network can accommodate is determined by the intersection capacity of the road network. This study aims to determine the magnitude of the intersection capacity, degree of saturation, delay and queuing opportunities at the RH-Mart Namlea City intersection, whether the solution or alternative solution to the traffic jam problem at the RH-Mart Namlea City intersection. This research was conducted at the unmarked intersection in the city of Namlea, especially the RH-Mart intersection. The intersection performance analysis includes capacity (C), degree of saturation (DS), delay (D); and the probability of queuing QP% 'was calculated using the MKJI 1997 method. The results showed that the intersection capacity (C) = 632.30 pcu / hour, the degree of saturation, for all directions at the intersection arm and for all survey days Ds <0.75, namely on working days obtained Ds = 0.071 and 0.083, for short days Ds = 0.087 and 0.068, and on holidays Ds = 0.068 and 0.070. it means that there is no need for improvement of the intersection geometry, control of total intersection currents, and control of the flow with signs to maintain the desired degree of saturation (DS ≤ 0.75). Because the Ds value obtained is very small there are no delays and queuing opportunities that occur. Keywords: Unmarked Intersections, Intersection Capacity, Degree of Saturation. Namlea

Abstract

Namlea Village is one of the villages in Maluku Province, Buru Regency, currently developing in terms of economy and population growth. Land-use changes have an impact on soil infiltration, with the amount of surface runoff which has the potential for flooding at several points to become a problem in Namlea Village, significant surface runoff on the clove flower road causes the drainage channel on the road to be unable accommodate the discharge of water that enters the drain. This research was conducted by referring to primary data and secondary data. Primary data, data obtained by conducting field surveys (research places/locations), while secondary data, data obtained directly from related agencies as supporting data in the final project writing. This. The planning analysis results with rainfall data taken from the BMKG (Meteorology, Climatology and Geophysics Agency). By paying attention to the hydrological design criteria table for the urban drainage planning system, appendix 8 and the data on water users in table 4.12 and population density projection data for 2015 taken from the statistical agency. Then the results of our planning analysis take a maximum plan age of 2 years with a maximum rainfall = 410,907 mm, with a planned discharge due to rainwater runoff Qp = 1,167 m3 / s and release due to household waste Qlimbah = 0.0025 m3 / s, then the total discharge Qtotal = 1.1695 m3 / s, with the results of the above analysis, the existing channel capacity is unable to accommodate water discharge due to rainfall or burst due to household waste because the current channel discharge is only able to accommodate a release of Q = 0.44 m3 / s with a volume capacity of V = 209,375 m3, while the volume capacity of the channel on Jalan Bunga Cengkeh is following the current population density and must be able to accommodate a discharge of Qtotal = 1.1695 m3 / s. With an average annual volume capacity of V = 25612.05 m3. The existing channel dimensions must be rehabilitated according to the planning analysis results that the author had planned with a trapezoidal channel cross-section. Keywords: Evaluation of drainage channels, channel capacity, due to rainwater discharge

This study aimed to determine the effect of NPK Phonska fertilizer and plant distance on the growth and production of corn plants. This research is expected to be useful as information material for farmers and related agencies to increase corn production. This research was conducted in Elfule Village, Namrole District, South Buru Regency. The implementation of this research was started from January 2020 to March 2020. The tools used in this research were hoe, machete, meter (measuring instrument. In contrast, the materials used in this study were corn seeds, NPK Phonska fertilizer. This research used a randomized block design. (RBD) Factorial pattern. The results showed that corn plants have unbranched stems. It tends to be cylindrical and consists of several segments and knuckles. Some shoots later will grow into cobs, male flowers, and female flowers in the knuckle in separate maize (diklin) in one plant (monoecious). Male cornflowers are ready for pollination 2-5 days earlier than female flowers (protandry), picking corn to be consumed as corn on the cob does not have to wait until the seeds are ripe. Still, it can be done ± four weeks after the plants' flower or can take the harvest time between the vegetable corn harvest and the harvest age j great dead cook. Corn cobs are rich in pentose, which is used as a raw material for making furfural. Genetically engineered maize is also now grown as a pharmaceutical producer.

Abstract

Mung bean is a short-lived annual plant of approximately 60 days, also acts as a tropical plant which throughout its life requires a hot atmosphere, which means that when in an area with low rainfall levels it is ideal if cultivating mung bean plants, the purpose of this study is to see the effect. Dose of Manure (Cow Feces) and Plant Distance on Growth and Yield of Mung Bean (Vigna Radiata L) in Batuboy Village). This research was conducted in Batuboy village, Namlea District, Buru Regency, and lasted from December 2016 to February 2017. The experiment's purpose was to determine and analyze the response of manure (cow feces) and spacing to the growth and yield of green bean plants. The experiment used a randomized block design (RBD) with a factorial pattern consisting of 2 factors, namely the provision of manure dose (first factor) and use of spacing (second factor). The first factor has three levels, namely K0 (without treatment), K1 (fertilizer dose of 1000 kg / h), K2 (fertilizer dose of 2000 kg / h). The second factor, the spacing consisted of 3 levels, namely J1 (50 x 10 cm), J2 (50 x 20 cm), J3 (50 x 30 cm), thus obtaining 9 treatments / combinations with 3 replications / group so that there were 27 units / units. trial. This study indicates that the application of manure (cow feces) 2000 kg/ha has a good effect on the growth and yield of green beans compared to others. This can be seen from the weight of production/plot 3.03 kg, while the best combination treatment is produced by a combination of 180 gr/plot manure and 50 x 30 cm spacing (K2J3).

Abstract

The amount of load received depends on the weight of the vehicle, the configuration of the axle, the contact area between the wheels and the vehicle and the speed of the vehicle itself. This will give a value of damage to the pavement due to wheel axle loads that pass each time on the road. The weight of the vehicle is transferred to the pavement through the vehicle which is located at the ends of the vehicle axle. Each vehicle has a different axle configuration. The front axle can be a single axle of the wheel, while the rear axle can be a single, double or triple axle. From the background above, the problem formulation in this study is what is the volume of traffic that is traversed by vehicles on the roads studied, especially Siahoni Village and how is the level of damage to the hot mix road in Siahoni Village. The method used in this research is in addition to the survey method, direct observation also uses the PCI method where the data obtained, both secondary data and primary data, will be analyzed based on the PCI method so that the results are in accordance with the problems in the field to solve these problems according to the needs desired by the users or owners who have technical interests. The results showed that The discussion and results of the analysis above can draw conclusions regarding the analysis of road damage as follows: 1. The number of vehicles every day that pass through Siahoni Village with the formula above can be seen that every day the vehicles passing the Batuboy Village road to Siahoni Village are 580 vehicles / day 2.
