Abstract

Sosialisasi terkait pemanenan air hujan merupakan langkah penting untuk mempromosikan konservasi sumber daya air. Metode ini melibatkan pengumpulan dan penyimpanan air hujan yang dapat digunakan untuk berbagai kebutuhan, seperti mencuci, menyiram tanaman, bahkan sebagai air minum dengan melewati proses penyaringan yang tepat. Masyarakat Desa Penfui Timur dipilih sebagai mitra karena melihat masyarakat yang sering mengalami kesulitan air bersih di saat musim kemarau sehingga harus membeli air dan memanfaatkan sumber air tanah. Sehingga melalui kegiatan ini masyarakat menjadi tahu keuntungan dalam menerapkan metode Rain Water Harvesting (RWH) diantaranya meningkatkan ketersediaan air, mengurangi banjir dan erosi, serta menjaga keberlangsungan lingkungan. Proses ini telah berhasil terlaksana dengan adanya pendidikan dan penyuluhan rutin kepada masyarakat, dukungan dari pemerintah, serta contoh langsung berupa pemasangan RWH pada tempat umum seperti sekolah dan kantor pemerintah untuk menunjukkan manfaat RWH secara langsung. Dengan sosialisasi yang efektif, masyarakat dapat memahami pentingnya pemanen air hujan sebagai solusi konservasi air yang berkelanjutan, meningkatkan penerimaan dan partisipasi dalam implementasinya.

Abstract

Development of socio-economic activities occurs linearly with respect to the road network. Along the edge of the Timor Raya Timor Raya road Km 8+800 to Km 9+000 the side barriers are now getting higher, both due to vehicle parking on the road body, as well as due to vehicles entering and leaving the parcel (access) and pedestrians on the shoulder of the road and road crossings. Traffic problems that arise due to the activity of vehicles parked on the road are of course detrimental to road users such as when the vehicle is parked or when the vehicle exits the parking lot, therefore parking controls on the Timor Raya road Km 8+800 to Km 9+000 is the most important thing to do to control traffic so that congestion, pollution, noise can be minimized. Based on the analysis conducted using the Indonesian Highway Capacity Manual (MKJI, 1997). It is known that the peak volume occurred on Monday, 08 May 2023 at 17.30-18.30 WITA with a volume of 2162.75 PCU/hour, a capacity of 2366.63 PCU/hour, and the performance of Jalan Timor Raya, Oesapa Km 8+800 to Km 9+ 000, is at service level E with a DS value of 0.91. with a light vehicle free flow speed of 35.8 km/hour and an average speed of 22 km/hour. in conditions without light vehicle (LV) and heavy vehicle (HV) parking on the road, enter service level D where the DS value reaches 0.78, with a capacity of 2781.83 pcu/hour, free flow speed of light vehicles 38.9 km/hour and an average speed of 28 km/hour. Whereas in conditions without parking at the entrance to the service level C where the DS value reaches 0.71, with a capacity of 3019.31 pcu/hour, the free flow speed of light vehicles is 42.6 km/hour and the average speed is 32 km /hour.

Abstract

A construction project is a series of activities to achieve a goal within certain time, cost and quality limits. Construction projects require resources, namely humans, materials, equipment, implementation methods, money, information and time (Kerzner 2009). Project resources are planned to achieve project goals within time, cost and quality constraints. The challenge in project implementation is how to plan an effective time schedule and efficient cost planning without reducing quality. In the road improvement project in Batuplat sub-district, the Earned Value method has not been applied as this method functions as a tool for evaluating project performance and the results of this evaluation can be used to estimate whether the project can be completed on time or not. From the results of initial observations, the author knows that in the project implementation process, weekly evaluations were not carried out, this could result in the contractor not knowing what obstacles could prevent the project from being completed on time. The author considers that the absence of this method cannot provide an estimate that this project can be completed on time because there are two possibilities that this project can be completed on time or not.

Abstract

Overcoming the problem of time delays requires handling using proven methods or alternatives such as adding work groups or adding working hours. Adding working hours and labor is usually used as a solution to speed up the completion time of a project because by adding working hours, the time that can be used to work increases so that the resulting production increases and the completion time. Adding working groups and working hours to the selected work items from the critical path, namely Class A Aggregate Foundation Layer, Wearing Layer Laston and Fc 15 mpa Concrete Structure produces a new minimum production so that the completion time of the three work items is reduced, but also increases the costs required to complete the work items. Adding Working Hours (Overtime) to the three work items on the critical path, the first hour of completion duration is reduced by 12.5% in the completion duration of the work item, the 2nd hour by 22.22% in the work item, the 3rd hour by 30% in the work item. While the cost of Class A Aggregate Foundation Layer, the 1st working hour cost is 0.15%, the 2nd hour is 0.31%, the 3rd hour is 0.31%. In the Wear Layer Laston work item, the cost is 0.08% in the 2nd hour, 0.16% in the 3rd hour and 0.16%. In the fc 15 Mpa Concrete structure work item, the 1st working hour is 2.01%, the 2nd hour is 4.01% and the 3rd hour is 4.01%. The addition of labor groups for the Class A Aggregate Foundation Layer work item, the duration is reduced by 32%, the Wear Layer Laston work item is 13%, and in the Fc 15 Mpa Concrete Structure work item is 50%. The cost of the Class A Aggregate Foundation Layer work item increased by 0.37%, the Wearing Layer Laston work item increased by 8.03% and the fc 15 Mpa Concrete Structure work item did not experience an increase.

Abstract

A project is a detailed series of activities within a limited timeframe aimed at achieving specific objectives. Resources such as manpower, equipment, materials, money, and time are crucial for project success. The research objective is to determine the impact of minimum production differences between equipment and labor on project completion time, costs, and profits. The completion time for the binder course work item, based on labor and equipment, is 0.83 days, with a minimum production used of 10,000 liters. Conversely, based on equipment's minimum production, the completion time is 0.47 days, with a minimum production used of 17,500 liters. This shows a difference in completion time of 0.35 days with a reduction of 0.43%. According to the Bill of Quantities (RAB) data, the project cost is lower compared to the project cost based on labor, equipment, and labor and equipment combined. The initial profit according to the Bill of Quantities data is Rp 337,328,068.10, and the profit based on minimum labor production is Rp 145,723,835.86, resulting in a profit decrease of -56.80%.

Abstract

One type of ceiling often found in commercial buildings today is gypsum board. Slowly, the ceiling of the house made directly from wooden ribs and plywood began to decrease, and in general, local artisans in the Oetalu area, East Penfui, Kupang Regency, are not yet skilled in installing gypsum ceilings and do not even know how to do it. What often happens is that foreign artisans from Java or Sulawesi do gypsum ceiling work. This is a problems for empowering and developing local artisans' skills. In addition to the problems mentioned above, to become a professional artisan in construction, you must be certified by a certification body and the public works department. The qualifications of gypsum ceiling artisans are at class/level 3, and their classification is gypsum ceiling artisans with the number TA013. Ownership of a craftsman's competency certification is an obligation for construction workers as regulated in the Construction Services Law. After that, a training activity was carried out with lectures and practical training for three days, starting from purchasing materials, assembling steel frames, and installing gypsum boards, and ending with finishing. The results of this training activity are that the training participants, in this case, members of the local artisans group, are skilled in gypsum ceiling work and are ready to become gypsum ceiling workers, ready to take the craftsman certification test organized by the association or public works department. There was a significant increase in knowledge and skills among local artisans in gypsum ceiling installation work.
