Abstract

The utilization of multilevel drip irrigation needs to be supported by adequate planting media so that the provision of irrigation water is optimal. The planting media used practically uses soil mixed with livestock waste compost and cocopeat in polybags. This test aims to determine the ability of drip irrigation water absorption by the planting media in the form of irrigation depth and soil moisture provision and prediction of irrigation application with a certain duration. The study was conducted on a ½” PVC pipe drip irrigation network with a 2 lt/hour emitter, on a land size of 2 m x 4m x 2m with a water source from PDAM water which is stored in a tank with a capacity of 150 liters and a height of 2.5 m. The test data taken includes data on the distribution of irrigation volume, irrigation depth and soil moisture. The results of the analysis showed that the distribution of drip irrigation depth in cocopeat media ranged from 7.5 cm - 12 cm in 5 minutes, while in rice husks the absorption was around 6.5 cm - 10 cm for the planting media level, with an average Cu of 96% which is very good. The maximum soil moisture that can be provided by four-tiered drip irrigation at a duration of 5 minutes is 30.5% in the early growth phase and at a duration of 10 minutes the average soil moisture is 15%, in the Vegetative phase of plant growth until fruit ripening. So the high irrigation infiltration rate in cocopeat media has the potential to be applied to plants that have long or deep roots, while planting media with rice husks has the potential to be applied to plants with short roots such as vegetables.

Abstract

The secondary pipe network in a multi-level drip irrigation network is a water source that will serve the drip irrigation network at each level. The amount of flow obtained by the drip irrigation network is highly dependent on the available head height from the water source. This study aims to determine the amount of flow discharge produced by the height of the water source head in a four-level drip irrigation pipe network, so that it can be used for optimal design of a multi-level drip irrigation network. Optimization of the irrigation network is reviewed against the amount of deviation of discharge from the primary network to the drip discharge, as the final result of irrigation to the plants. The test was carried out on a 4-level drip irrigation network with a water source height from the reservoir of 3.21m with a capacity of 200 liters. The head variation consists of four types according to the amount of height of the drip irrigation network to the surface of the reservoir water. The main data analyzed are the volume of flow collected, discharge, speed and deviation of discharge or speed. While the presentation of the results is displayed in the form of regression graphs between the two test parameters, so that they can be applied generally. In the secondary pipe, there is an average difference in flow velocity of around 0.05 m/s in each network, with the lowest secondary flow rate deviation obtained at a small head of 0.2 cm3/s between the fourth and third floors, while the highest discharge deviation is obtained on the first and second floor networks, which is around 1.6 cm3/s. Low vt deviation is obtained at a head below 2.3m and the highest occurs at a head above 2.3m. The difference in head in the primary and secondary distribution networks does not have a significant effect on the distribution of drip irrigation flow, if the drip points are more numerous, the deviation is still within reasonable limits.

Abstract

Sebagian besar masyarakat desa Sukarema memiliki mata pencaharian sebagai petani. Selain menanam padi untuk kebutuhan pribadi, petani di desa Sukarema juga menanam jagung untuk dijual dalam keadaan sudah dikeringkan dan dipipil. Jagsung yang sudah dipipil menghasilkan limbah berupa bonggol (janggel) jagung yang biasanya dikemas ke dalam karung kemudian dijual dengan harga lima ribu rupiah per karungnya. Hal inilah yang mendasari munculnya program kerja budidaya jamur janggel sebagai upaya untuk mengoptimalisasikan pemanfaatan bonggol (janggel) jagung untuk menaikkan nilai ekonomi dari janggel jagung tersebut. Budidaya jamur janggel membutuhkan bahan – bahan penunjang pertumbuhan jamur seperti urea, bekatul, dan ragi tape. Pembuatan media tanam budidaya jamur janggel ini menggunakan beberapa perlakuan yang berbeda untuk melihat perbandingannya. Hasilnya, penggunaan nutrisi yang tepat sangat mepengaruhi pertumbuhan jamur janggel.

Abstract

The Gumantar Village community is a community located in the hills with terraced and sloping village conditions. Most of the community has yards and gardens, although not very large with terraced land conditions. The water source of the Gumantar Village Community comes from the upstream hillsides, with the number of hamlets as many as 16 hamlets with a population of around 2000 people and most of them are field farmers. Considering the potential of the surrounding land which is very large and in the form of terraces, it is necessary to provide counseling to the community on how to utilize limited water sources for farming activities with a drip irrigation system. To help the community, counseling is needed so that the community quickly understands the drip irrigation system. This community service aims to provide efficient irrigation counseling, namely drip irrigation, to encourage farming to be carried out around the yard. The community service consists of location survey activities, counseling, discussion and question and answer sessions, and evaluation. This community service has succeeded in providing counseling to 35 people consisting of housewives and fathers, as well as young people from the Dasan Tereng Hamlet mosque. Participants have gained knowledge about drip irrigation and obtained examples of the use of drip irrigation in yards and dry land, so that people are able to utilize limited water in the dry season for agricultural purposes in their yards

Abstract

East Jembatan Kembar Village is located in an earthquake-prone area in West Lombok Regency, making it essential to enhance community capacity in disaster preparedness. This outreach activity aimed to increase community awareness of earthquake preparedness and to initiate the formation of a community-based structure capable of acting during emergencies. The method used included face-to-face counseling and participatory discussions involving the village head, village staff, community leaders, youth, and local residents. Topics covered included basic knowledge of earthquakes, appropriate actions before, during, and after an earthquake, and the importance of forming a Community Disaster Resilience Group (KMTB). Although the activity was conducted in the morning and received enthusiastic support from the village government, public participation was limited due to time constraints with residents' daily work routines. Nevertheless, the activity successfully delivered key information to attendees and led to the formation of the Community Disaster Resilience Group as a continuation of the program. This group is recommended for immediate formalization by the village government so that it can establish statutes and bylaws, build cross-sector coordination, and fulfill its role in preparedness and emergency response. The results demonstrate that collaborative efforts between local authorities and communities can be an effective strategy for building village resilience to disasters.

Abstract

Multilevel drip irrigation is an irrigation method that supports water-saving agricultural activities in limited areas by channeling water through perforated pipes from emitters. An ideal multilevel drip irrigation system can provide the same volume of droplets to plants, so that the distribution of irrigation water and the uniformity of drip irrigation are important factors that need to be considered when using drip irrigation to provide plant irrigation. This research aims to determine the effect of using variations in the diameter of PVC pipes as primary pipes on the distribution of drip irrigation and its uniformity. The primary irrigation network tested for each network to the 1st floor to the 3rd floor consists of ½", ¾" diameter and 1" pipe, while the secondary and lateral drip pipe networks use ½" PVC. The test was carried out on an area of 4 m x 1 m x 1.8 m with a distance between levels of around 0.9 m, with an irrigation water source from a 200 liter tank placed on a tower with a height of 2.5 m.The results of the research show that the discharge produced by the main pipe is different on each floor of the irrigation network, on the 1st floor the discharge is 127.13 cm3/second and on the 3rd floor the discharge is 120.91 cm3/second, while on the 2nd floor the discharge is between the values of the 1st floor discharge. and 3rd floor. Regarding the results of the distribution of drip irrigation water volume, it is known that the average does not show significant differences due to differences in network operations or due to differences in pipe diameters used, where the values for floors 1 to 3 are respectively 68.75 ml, 68 .47ml, 68.19ml. The uniformity of drip irrigation shows results above 94% on all network floors and is considered very good.

Abstract

Multilevel drip irrigation is an irrigation method that supports water-saving agricultural activities in limited areas by channeling water through perforated pipes from emitters. The ideal multistage drip irrigation system can provide the same drip volume to plants, so the distribution of irrigation water and its depth need to be important factors to pay attention to in order to provide optimal plant irrigation. This research aims to determine the effect of using variations in primary channel pipe diameter on the distribution of drip irrigation and the depth of infiltration of irrigation products in a 3 (three) tier drip irrigation network. Tests were carried out on primary pipes from floors 1 to 3 with a diameter of ½", ¾" and pipes 1", with lateral drip pipes with ½" PVC. The size of the test field is 4 m x 1 m x 1.8 m and the distance between levels is around 0.9 m and the irrigation water source from a 200 liter tank is 2.5 m high. The research results showed that irrigation distribution results were quite good at all levels of the irrigation network, namely 70 ml and 68 ml. Irrigation patterns do not have a significant effect on the results of irrigation distribution due to variations in primary pipe diameter. A soil composition of 30% compost has achieved irrigation infiltration with a depth of 21 cm, including the fastest, namely 25 minutes and for 70% soil, an irrigation infiltration time of 35 minutes is required.
