Abstract

Desa Setanggor dilewati oleh sebuah sungai yaitu Sungai Berampes yang dapat dimanfaatkan sebagai penyediaan air di musim kering melalui pengolahan kualitas air. Sebagian besar masyarakat di Desa Setanggor Kecamatan Praya Barat belum memanfaatkan dan terlayani oleh jaringan air bersih PDAM sehingga memanfaatkan air dari sumur bor komunal sebagai penghasil air baku sehari-hari. Namun, karena beberapa keterbatasan teknis dan non-teknis menyebabkan ketidakcukupan untuk pemenuhan kebutuhan sehari-hari masyarakat sekitar. Akibatnya sebagian masyarakat mengalami kekurangan air bersih terutama di masa kemarau panjang. Hasil instalasi dan uji fungsi alat menggunakan sampel air dari sungai Berampes menghasilkan 4 dari 5 nilai parameter kualitas air yang sesuai dengan standar dari Permenkes 32/2017, kecuali temperatur. Oleh karena itu, disarankan lokasi dan waktu pengambilan sampel air serta perlakuan pra-pengujian mendapatkan perhatian dan porsi khusus dalam proses pengujian, selain jenis material gradasi partikel penyaringnya.

Abstract

The problem of clean water for people in the highlands always arises every dry season. Getting clean water every day requires a lot of effort to find a water source that is very far away. Some people even have to spend additional money to get clean water. This is also the case with people in Batulayar sub-district who live in the highlands, especially in the mountains. Surface water sources are not available so that it becomes a routine problem every year. In overcoming this problem, some people make rainwater reservoirs either in groups or individually. The reservoir is made with several materials in the form of a reservoir by making a hole in the ground surface covered with plastic or tarpaulin and a reservoir made of brick/brick masonry. The method of capturing water is directly from the ground surface by making a channel and there is by making a reservoir from local materials in the form of bamboo which then the captured water is channeled into the reservoir. The use of local materials in the form of bamboo is very potential to be used because in the Batulayar area, especially in the mountains, the availability of bamboo is very abundant. Bamboo with an age of 3 years already has quite high strength both for water flow materials and as construction materials. The weakness that is still faced by the community in utilizing bamboo is the connection method which is still very simple, so that when it rains with high intensity the connection comes loose. In using bamboo as a rainwater catchment network, it is very important to socialize the right connection model to be used in capturing rainwater.

Abstract

Pembagunan permukiman dan pusat-pusat perekonomian di Desa Medana mengalami pertumbuhan yang sangat pesat seiring dengan perkembangan kabupaten Lombok Utara sebagai kabupaten baru. Semua aspek berkembang sangat cepat seperti permukiman, pertokoan, perkantoran maupun tempat-tempat pariwisata. Berbagai kebutuhan sarana dan prasarana penunjang pertumbuhan perkotaan tersebut seperti parkir, jalan, sistem dranase, pembuangan limbah, air bersih dan telokomunikasi. Salah satu dampak dari pertumbuhan tersebut yaitu penggunaan perkerasan permukaan lahan dengan menggunakan asphlat, beton serta paving block. Penggunaaan perkerasan tersebut yang rata-rata kedap air akan menyebabkan kecilnya volume air yang masuk ke dalam tanah sehingga menyebabkan terjadinya banjir, genangan dan turunnya permukaan air tanah. Dalam upaya mengurangi permasalah tersebut sangat diperlukan adanya inovasi sistem perkerasan ramah lingkungan yang tetap memberikan konstribusi terhadap air bawah permukaan, mengurangi banjir, konservasi air serta menjaga siklus air permukaan dan bawah permukaan. Pemanfaatan sistem perkerasan grass block paving atau dengan grass block dengan pengisi material alam (batu pecah atau coral) akan dapat mengurangi terjadinya genangan atau banjir, dimana air limpasan permukaan akan masuk kedalam tanah melalui pori paving block. Sehingga dengan demikian limpasan dapat dikurangi dan air yang masuk menjadi infiltrasi akan selalu tetap dijaga. Pelaksanaan pengabdian diikuti oleh seluruh perangkat desa, masyarakat, tokoh masyarakat, karang taruna, serta mahasiswa kuliah kerja nyata Universitas Mataram

Abstract

Pertanian di lahan kering Gumantar, saat ini telah didukung oleh jaringan irigasi air tanah (JIAT) dalam dengan jaringan perpipaan dan sistem bok outlet dalam pendistribusian air irigasinya. Pada cara irigasi tersebut irigasi dilahan pertanian diberikan dengan cara penggenangan sekitar 2 jam dan kemudian diistirahatkan karena terbatasnya pompa. Memperhatikan pemberian irigasi dengan sistem yang ada sangat boros dengan air dan banyak lahan dengan luasan yang kecil berpotensi mendapat air dari jaringan JIAT sangat berlebihan, maka perlu dilakukan uji sistem irigasi hemat air untuk untuk luasan kecil, untuk membantu efisiensi penggunaan air dilahan kering JIAT Gumantar. Untuk itu sistem irigasi sprinkler kecil yang jangkauannya pendek akan diuji dilokasi ini, agar nantinya dapat digunakan sebagai alternatif dalam irigasi pada lahan yang kecil. Uji ini dilakukan pada luas lahan sekitar 3 are dengan uji sprinkler kecil 24D Netafim dan jaringan distribusi digunakan pipa pvc dan sumber air dari jaringan JIAT. Uji dilakukan terhadap kinerja sprinkler dalam memberikan irigasi. Data hasil uji yang dianalisis mencakup data radius irigasi, kedalaman dan durasi. Hasil penelitian menunjukkan bahwa terjadinya peningkatan kedalaman irigasi yang diperoleh dengan ditingkatkannya durasi irigasi dan pada durasi 1 jam diperoleh kedalaman irigasi 7 cm dan untuk durasi 2 jam diperkirakan mencapai kedalaman 14 cm.

Abstract

Selengen Village is one of the villages in North Lombok Regency that always experiences drought and lack of clean water every year. The problem of clean water availability is caused by limited water sources on the surface. The frequency of rainwater in Selengen Village is very small and with very low intensity. In order to meet the need for clean water, the community has to pay additional costs to buy clean water or wait for a drop from the government. The Selengan Village community has limited information regarding simple methods that can be used to collect clean water sourced from rainwater. The method used to introduce rainwater capture as a source of clean water is to provide direct outreach to the Selengen Village community about rainwater storage in the form of ABSAH (Artificial Aquifer for Rainwater Savings). The ABSAH method can be done individually or in groups. The socialization was carried out at the Panggung Barat Hamlet office involving the community consisting of farmer groups, community leaders, youth organizations and housewives. The result of the socialization regarding the introduction of artificial rainwater aquifers is the high desire of the community to create rainwater storage, either independently/individually or in groups. In the process of making it, the community hopes to get assistance from the implementation team so that the calculation of the storage volume is in accordance with the volume of water used. Apart from that, the community also hopes to be given drawings of storage designs, installations for collecting water from the roofs of houses and designs of distribution networks to people's homes.
