Abstract

Dusun Kerujuk adalah salah satu wilayah di Kabupaten Lombok Utara yang terdampak parah atas kejadian bencana gempa Lombok pada Juli 2018 yang mengakibatkan rusaknya berbagai infrastruktur termasuk diantaranya infrastruktur air bersih. Perbaikan infrastruktur telah diupayakan oleh pemerintah daerah setempat, namun masih terdapat kekurangan khususnya pasokan air untuk kebutuhan Masjid Nurul Hidayah dan masyarakat di sekitar masjid. Sehingga tim bermaksud membantu menambah jaringan perpipaan menuju masjid agar kebutuhan air untuk kegiatan ibadah di masjid dan bagi masyarakat yang tinggal di sekitar masjid dapat terpenuhi secara layak. Pipanisasi dimulai dari bagian intake penyadap yang diletakkan pada mata air yang ada di bagian hulu dusun, peletakan dua tandon di sekitar masjid serta pemasangan jaringan pipa yang membawa dan mendistribusikan air ke masjid dan rumah warga di sekitar masjid. Meskipun pipanisasi yang dipasang masih semi permanen namun masyarakat dapat langsung memanfaatkannya untuk memenuhi kebutuhan air bersih sehari-hari melalui jaringan pipa tersebut dalam menghadapi masa tanggap darurat gempa

Abstract

The "Sapu sae" waste cooperative is a joint effort of community groups in Jelantik Village to collect waste, especially plastic waste, to overcome the problem of plastic waste while improving the welfare of the residents. However, this cooperative is currently no longer operating due to various reasons. Difficulty in collecting waste due to residents' refusal, lack of administrative and financial management capabilities and unclear management of the cooperative are the main reasons why this cooperative is unable to survive. This activity aims to revive village waste management activities. This service activity uses a solution approach method for cooperative problems. The activities are carried out in several stages, including the revitalization of cooperatives, simple bookkeeping and finance training for administrators, waste management training for members, providing minimal assistance for cooperatives and closing with mentoring and evaluation. This activity has been carried out and received a warm welcome from the Jelantik Village community. The waste cooperative has been revived with new legal administrators who have been given bookkeeping training. Cooperative members were also given training in making handicrafts made from waste. Service activities also provide minimal means for carrying out cooperative activities in the form of garbage collection sacks, member savings books and cooperative administration book packages. This activity has been evaluated and shows positive developments with the return of the cooperative and increasing public awareness in waste management.

Abstract

Peak discharge flood analysis is very crucial in waterworks design. The proper design flood discharge will produce effective construction dimensions as project requirement. Therefore, flood design calculations must be analyzed using appropriate methods. The problem in estimating design flood discharge is usually found in ungauged watersheds which do not have any water discharge measuring equipment.This study wants to test the flood design method using rain data input to be applied to the Babak River, so the result can be used as a guide in the selection of flood discharge calculation techniques in other ungauged watersheds.The accuracy test is carried out by comparing the results of these methods with the flood design resulted from a frequency analysis of the Annual Maximum Series. Based on the results of the calculation, the peak flood of the Harpers method has the smallest RE and RMSEP values are 8.960% and 88.546 respectively. Thus, it can be concluded that the calculation of the design of the flood peak Haspers method has the best accuracy of the analysis results when compared with the Melchior and Weduwen methods for Babak River.

Abstract

Farming on narrow land is mostly done in urban areas with limited water sources, because irrigation canals are not accessible. In vacant land around housing, urban communities can usually still use it for farming, even with limited water sources, shallow wells. To support urban farming, it is necessary to support an efficient irrigation system such as small sprinkler irrigation on the market. This study aims to test the ability of the Meganet 24D Netafim small sprinkler on irrigation capability, both in depth and soil moisture (w) and uniformity (Cu) produced, on an area of ​​about 1 acre. The test was carried out on 4 variations of discharge (Q), sprinkler distance (Ls) and sprinkler height (hs). Data analysis was carried out on Q, w and large Cu. Based on the analysis results obtained Cu above 85% at 0.5 m and 0.75 m with Ls 3.5 m to 5 m and flow rate Q4 = 0.42l/sec to Q1 = 0.57/sec. At a duration of 20 minutes, the irrigation depth was 20 cm and w obtained about 9% - 13%.

Abstract

Estimated flood discharge value for water structure design, ideally determined based on the frequency analysis of measured discharge data. However, the measured discharge data is often not recorded or if the length is limited. So, it needs the technique in getting the design flood value from rain data through the Synthetic Unit Hydrograph (SUH) method. This study examined the suitability of the three (3) SUH methods (Nakayasu, Limantara and ITB2) in generating the design flood discharge and compared it with the Observed Unit Hydrograph (OUH) of the elongated shape watersheds, namely Sidutan and Reak. The main values that are compared are peak discharge, peak time, and base time of HSS to the HSO value. The results obtained from the Sidutan watershed and the Reak watershed are both elongated shape watershed, have almost the same length as the main river, but the area of the Sidutan watershed is greater than Reak watershed. The average OUH of both watersheds indicated that both Qp and Tb of the Sidutan watershed are greater than Reak, but the time peak hydrograph (Tp) was reached at almost the same time. The SUH method that produced unit hydrographs closest to OUH is Nakayasu, then ITB2 and Limantara, respectively.

Abstract

Determining the rain pattern distribution is believed to affect the design flood. Providing hourly rainfall observations can be obtained, and the distribution patterns can be determined. However, in areas that do not have one, flood discharge calculations are carried out by distributing daily rainfall using empirical methods. This study distributes daily rainfall into hourly rainfall in the Jangkok watershed using ABM and Mononobe methods and calculates the flood hydrograph using the Nakayasu model. The synthetic unit hydrograph obtained from the actual rain distribution is then compared with the unit hydrograph generated from the empirical distribution, then the deviation is measured. The results showed that the Mononobe and ABM rain distribution gave the same hydrograph shape as the observation one, only for 2 hours of rain duration. As long as the rain lasts 3-6 hours, the peak flood discharge (Qp) tends to be lower, 7-20% for Mononobe and  2-7% for ABM. Then the Qp becomes overestimated (5-12%) for a rain duration of >6 hours. Mononobe gives the same flood peak time (Tp) as observation rain for 1-5 hours rain duration and becomes 1 hour earlier for >6 hours. In contrast, ABM produces peak times 1 hour longer than hydrographs with observation rain. Generally, the two methods provide a more significant hydrograph deviation for a longer duration of rain.
