Analisis Rute Jalan Pengangkutan Sampah di Kota Makassar (Studi Kasus: Kecamatan Tamalanrea)

The rapid development of urban development in Indonesia, followed by an increase in migration of rural people to the cities most impact on increasing the number of urban dwellers is also comparable to the waste that will be generated. But not directly accompanied by an increase in waste infrastructure by the government, consequently there is no maximum services and a decline in the quality of the environment, especially on the problem of transporting municipal waste. This research is intended to study the transport of waste in the city of Makassar, particularly in District Tamalanrea. This type of research used in this study is a survey and investigation on the ground. Results of research in the field shows that the waste transportation system in District Tamalanrea Makassar done with 2 (two) ways: door to door and placement of garbage containers in TPS (Disposal meantime). Transporting waste that exists today in the District Tamalanrea Makassar is not effective yet. Where to dump truck DD 9037 AN only operate 1 rit/ day (5 hours) and the number of bins to be transported each day exceeds the capacity of the dump truck itself. As for the arm roll truck DD 9107 AB operates through the Makassar pioneering road axis which is the congestion points. Waste transportation route for effective and efficient arm roll truck heading TPS BTP Tamalanrea is to pass Jl. Tamangapa Raya, Jl. AMD, Jl. Moncongloe, Jl. Katimbang Raya and Jl. Tamalanrea Raya. Where the route is 1 mile shorter than the usual route traveled and can save time travel approximately half an hour. To maximize the performance of the dump truck DD 9037 AN rearrangement is necessary to do the service of transporting waste to the waste volume in 1 ritasi according to the capacity of the dump truck. With the rearrangement, it takes additional time per day operation. So in 1 day, dump trucks hauling trash can operate as much as 2 times ritasi. Needs of the waste hauler vehicles (dump trucks and truck arm roll) needed in Makassar is 10 units of 6 m3 capacity dump truck, and 3 units arm roll trucks capacity of 10 m3

Unconfined Compressive Strength Of Sedimentary Soil Stabilized With Portland Cement With Varying Curing Time

Soil improvement is commonly carried out in construction work with the aim of increasing the bearing capacity / strength of the soil so that it can carry the construction load that will stand on it. The method that is often used is soil stabilization with the addition of stabilization materials. In this study, soil stabilization was carried out with the addition of Portland Cement. This research begins with soil sampling and laboratory testing to determine the physical and mechanical properties of the soil, followed by making soil samples for Unconfined compressive strength testing with 3 variations of cement, namely 5%, 10%, and 20%. From the results of this study, it is known that the soil sample has a moisture content of 97.13%, specific gravity of 2.51, liquid limit of 33.80% and plasticity limit of 22.52% with plastic index value = 11.28%. Based on the soil classification system with the USCS (Unified Soil Classification System) method, sedimentary soil types include CL (Clay-Low) soil types, clays with low plasticity values. Unconfined compressive strength testing on sedimentary soil samples without portland cement obtained a compressive strength value of 0.352 kg/cm2. And the soil stabilized with various variations of Portland Cement obtained the highest compressive strength value of 14.45 kg/cm2, namely in the soil sample + 20% cement with 28 days curing time. The results showed that the value of Unconfined compressive strength for sedimentary soil dredging dam bili-bili stabilized with Portland cement tends to increase its bearing capacity / strength with the addition of the percentage of Portland cement and curing time, with this value the category of hard soil consistency obtained can be used for building structures and road base soils

Characteristics of AC-WC Asphalt Concrete Mixtures with Polystyrene Addition

The top layer of pavement that functions as a wear layer is called AC-WC/ Laston. Improving the quality of flexible pavement continues to be developed in order to create transportation support facilities that are safe, strong and durable, but still economical. The use of additives is one way out that can be done in order to get a high quality product. The purpose of this research is to identify the optimum asphalt content to be used in the manufacture of polystyrene asphalt mixtures and to determine the characteristics of asphalt mixtures using polystyrene additives. The method used was to add polystyrene in the form of styrofoam which had previously been dissolved using gasoline into hot asphalt with a percentage of polystyrene mixture of 3.0%, 3.5%, 4.0%, 4.5% and 5.0% of the optimum asphalt content used. Based on the results of testing specimens with additional polystyrene, VIM and VMA values increased at levels of 3.0% to levels of 4.5% exceeding the upper limit of VIM specifications, but still within specifications. The stability value increased along with the increase of polystyrene from 3.0% to 5.0%, where this value meets the specifications. The flow value increases from 3.0% to 3.45% levels exceeding the upper limit of the specification then decreases after 3.45% levels to 5.0% levels where the flow value meets specifications. The conclusion that can be drawn is that the addition of polystyrene mixture in AC-WC can increase the hardness level of the Laston mixture

Clean water is one of the basic human needs. However, the problem now, especially in big cities is that theneed for clean water is often not met properly because the sources of clean water are decreasing. Groundwater is one ofthe sources of clean water that is most widely used by humans to meet the needs of clean water because the amountreaches 30% of the total freshwater on earth so that the use of groundwater is one of the most efficient ways to obtainclean water needs. Posyandu Lestari is a public facility that requires a source of clean water. To overcome the problemsat the posyandu, it is using groundwater as a water source. As for the targets and outputs in the implementation of thisPkM are (a). Fulfillment of clean water by utilizing groundwater through wellbore (b) Knowing the role of a wellbore inincreasing efficiency in meeting the need for clean water for Posyandu Lestari in Mambue Hamlet. (c) Increase thefulfillment of clean water needs by utilizing groundwater through drilled wells by Posyandu in Mambue Hamlet

One source of clean water that is most widely used by humans is groundwater. Not all of the residents inMambue hamlet can get clean water easily. To meet their daily water needs they usually take it directly from the nearestwater source. Groundwater is an alternative to getting clean water supply, but it is a big cost to make bore wells so thatpeople do not make bore wells. To overcome the problem of the community in the village of Mambue is to usegroundwater as a water source. As for the targets and outcomes in the implementation of this Ibm are (a). Making borewells as an alternative supply of clean water. (b) Determine the role of a wellbore in increasing efficiency in meeting theneeds of clean water for the community in Mambue Hamlet. (c) Determine the proportion of meeting the need for cleanwater by utilizing groundwater through drilled and non-groundwater wells by the community in Mambue Hamlet
