Abstract

Bendung merupakan salah satu infrastruktur vital dalam sistem irigasi yang berperan penting dalam pengelolaan sumber daya air untuk mendukung produktivitas pertanian. Kinerja optimal bendung sangat bergantung pada kondisi fisik dan teknisnya, yang perlu dijaga melalui pemeliharaan rutin, berkala, maupun rehabilitasi. Penurunan kinerja bendung dari waktu ke waktu dapat memengaruhi fungsi layanan irigasi, yang pada akhirnya berdampak pada hasil pertanian. Penelitian ini bertujuan untuk menganalisis kinerja dan merumuskan langkah-langkah peningkatan fungsi Bendung Way Lo yang terletak di DAS Way Apu, Kabupaten Buru, Provinsi Maluku. Bendung Way Lo berfungsi mengaliri Daerah Irigasi seluas 1.500 Ha, namun menghadapi berbagai permasalahan seperti kerusakan pada mercu bendung, sayap hulu dan hilir, pintu penguras, lantai hilir bendung, serta pintu intek. Kerusakan ini sebagian besar disebabkan oleh kurangnya pemeliharaan berkala dalam beberapa tahun terakhir, sehingga berpotensi menyebabkan kerusakan permanen jika tidak segera ditangani. Penelitian ini dilakukan dengan metode observasi lapangan, evaluasi kinerja struktur, dan analisis kebutuhan pemeliharaan serta rehabilitasi. Hasil penelitian menunjukkan bahwa kondisi beberapa elemen struktur Bendung Way Lo berada pada kategori rusak ringan hingga berat, yang memerlukan langkah-langkah pemeliharaan dan rehabilitasi untuk mengembalikan fungsinya secara optimal. Rekomendasi yang dihasilkan meliputi pemeliharaan rutin, rehabilitasi ringan pada kerusakan minor, dan rehabilitasi berat pada kerusakan kritis. Peningkatan fungsi bendung melalui perencanaan pemeliharaan yang sistematis dan berkelanjutan diharapkan dapat menjamin keberlanjutan layanan irigasi, mendukung produktivitas pertanian, serta menjaga ketahanan infrastruktur bendung di masa mendatang.

Abstract

The Ariate - Tanah Goyang road section is a road section in Huamual District, West Seram Regency with a road length of 6 KM and a width of 4 M which was built with the aim of facilitating access for people to travel to the Regency Capital. This road section is a location where water puddles often occur when it rains due to the condition of the drainage channels which do not distribute water runoff properly because most of the channels do not have a drainage system. This is what causes problems with the road structure because it is unable to accommodate excessive standing water, causing damage to surface runoff. Based on the results of a 10-year return period calculation, the design rainfall was 195.884 mm, with a rainwater discharge on the Ariate - Tanah Goyang road section of 0.650 m3 and the planned cross-section type was a trapezoidal cross-section with a channel top width of 110 cm, channel bottom width of 61 cm and channel depth 80 cm. And the population growth rate (r) is 0.14% of the annual percentage for the projected population for the next 5 years is 1,309 people and the dirty water discharge in the drainage channel is 0.004 m3/hour/day.

Abstract

Drainage is an important component as a complementary building for roads. The drainage system was built to channel water discharge originating from the hydrological cycle and waste water from household and community activities. A well-built drainage system can prevent waterlogging which can disrupt the activities of the surrounding community and can also prevent road damage. This research method was carried out directly at the research location to obtain existing data directly from the field and library research. Based on the planned discharge, the author uses the People's Log Distribution III, to calculate the dimensions of the drainage channel on the Loki village road. From the results of research and drainage planning calculations, it was found that the planned water discharge on the Loki village road was 0.472 m3/second. And from the results of planning the channel dimensions, it was obtained that the width of the top of the channel was 90 cm, the width of the bottom of the channel was 55 cm, and the depth of the channel was 75 cm.

Abstract

Water is the most essential resource in life. In every activity of life, not only humans but all living beings need water. The issue of clean water availability is something important that cannot be separated from the fabric of life. In Lohiatala village, the water source is taken from the river, then pumped to the upper settlement and stored in reservoirs, followed by distribution to distribution tanks and dispersed through 6 faucet points scattered throughout the village. This research aims to determine the population and clean water needs until the year 2043. In the research, the need for clean water in the village of Lohiatala is predicted using a population projection calculation method with an arithmetic approach, estimating a population of 782 people by 2043. Based on this population number, the required amount of water in the village of Lohiatala is 14,097 liters per hour or 0.00391 m³/second. To optimize the distribution of clean water, it is necessary to calculate the pipe diameter from the distribution tank to the sixth faucet; the result obtained by the researchers is 10 inches (taken from the calculation of the largest pipe diameter).

Abstract

Water is a primary human need that must be met, but overtime the rate of population growth, the need for water in Amdasa Village, Wertamrian District, Tanimbar Islands Regency is decreasing. Increased water use is sometimes not accompanied by the management of new water sources due to the lack of information about the potential of groundwater sources. Geoelectric surveys will provide potential difference values, current strength, and rock specific resistance values. The value of the rock's specific gravity is then further processed to obtain the value of the specific gravity of each rock layer. The research location has good aquifer potential indicated by the discovery of aquifer layers at shallow depths from the surface of 6 meters and up to 13 meters with various aquifer thicknesses and groundwater well design with a drilling depth of ± 16 meters for points 01 and 03.

Abstract

Water is a primary human need that must be met, but as time increases, the rate of population growth means that water needs are increasingly not being met. The geoelectric method is a geophysical method that utilizes electrical properties to interpret the earth's subsurface. The main aim of the geoelectric method is to find the resistivity value of a rock. The higher the resistivity value, the more difficult it is for the rock to carry an electric current, and vice versa. For this reason, one solution to meet the needs of the Lorulun Village community is to search for groundwater aquifers using one of the methods that can be used, the geoelectric resistivity method. The data collection and analysis method used in this research is to conduct a survey at the location to review and see the conditions directly at the research location. Identification To determine the existence of a water-bearing layer at a certain depth, we can use geophysical methods, namely the geoelectric resistivity method, to obtain an overview of the soil layers below the surface. Apart from that, it can also predict the potential for deep and shallow groundwater in the research area. The problem in this research is analyzing deep groundwater sources based on the characteristics and implementation of geoelectric results and the aim of this research is to conduct a survey and design deep groundwater wells based on the characteristics and implementation of geoelectric results in Tumbur Village, Wer Tamrian District. The data is processed based on the apparent resistivity equation, so that the apparent resistivity value (ρa) is obtained by entering the values ∆V, I, a, and K into the Microsoft Excel program. Then processed using RES2DINV software. The water source is at two points, namely geoelectric drilling points 01 and 02, respectively, where the aquifer is found. The casing screen installation process is placed at 3 meters and 12 meters. The use of gravel packs from a depth of 2 to 12.5 meters is to protect the drilled wall hole from landslides and also act as a filter for mud or other materials entering the screen. and with a depth of ± 15 meters, the resistivity shows a brackish water aquifer. This is caused by the influence of seawater intrusion By conducting a survey and designing a deep-ground water well based on the characteristics and implementation of geoelectric results in Tumbur Village, Wer Tamrian District,
