Abstract

The Plantation Network has a land area of ​​375 ha. Population which is directly proportional to the necessities of life, one of which is in the food sector, has made the government take the initiative to meet the needs and welfare of the community with productive agricultural land and fields. The data includes secondary data on 10-year rainfall from Depati Parbo and Kayu Aro Station and 10-year climatology from Kayu Aro Climatology Station. The calculation method used is the rainfall intensity Average method, Evapotranspiration modification Penman method, Debit danalan DR.FJ Mock method, cropping patterns, and irrigation water needs. Related to the calculation of 6 alternative cropping patterns with different types of plants and different initial planting plans by making comparisons with the existing discharge factor (Q80). Obtained that the cropping pattern is very possible, namely using the cropping pattern PADI-PADI-PALAWIJA. The most efficient and optimal planting pattern is that this cropping system consists of PADI-PADI-ON with large water demand in tertiary plots (NFR tertiary plots) producing 0 - 1,308 ltr / sec/ha with a maximum of 1,308 ltr / ha / February II, while the need for irrigation water in the intake (DR intake) ranges from 0 - 1,615 ltr sec/ha with a maximum of 1,615 ltr / sec/ha in February II. The available debit and debit in the Irrigation Network Planning Mark is very abundant with the mainstay discharge (Q80) for irrigation, the maximum available debit (Q80) can occur in November with 202,207 ltr / sec/ha and the minimum in August with 115,012 ltr / sec / Ha. Based on the results of the discharge and water above, it can be determined about the ratio of water/air equilibrium between discharge and water Q80 and the need for irrigation water requires a large/adequate surplus.

Abstract

Perkembangan pertumbuhan kota meningkat sehingga fenomena yang berkaitan dengan sumber daya air semakin meningkat. Pertumbuhan penduduk setiap tahun bertambah menyertai pertumbuhan kota, menjadikan pemanfaatan air tanah semakin meningkat. Fenomena yang terjadi adalah bahwa ketersediaan lahan untuk prosesnya terjadinya resapan air ke dalam tanah semakin berkurang, dimana luasan lahan yang ada sangat tidak mencukupi resapan air ke dalam tanah. Di samping itu, resapan air ke dalam tanah dipengaruhi tingkat permeabilitas dari jenis tanah pada lingkungan daerah sekitar resapan. Akibat dari jumlah resapan air ke dalam tanah yang tidak seimbang dengan jumlah pemakaian air tanah yang digunakan mengakibatkan terjadinya penurunan muka air tanah dengan disertai penurunan lapisan tanah. Bila hal ini terjadi secara terus menerus menjadikan elevasi permukaan tanah akan lebih rendah dari permukaan laut. Untuk mengantisipasi hal tersebut terjadi, maka penelitian ini melakukan kajian tingkat permeabilitas daya resap air untuk macam jenis tanah dengan melakukan tes-tes tanah, sehingga dapat diketahui titik imbang antara jumlah air tanah yang dapat diambil dengan air yang dapat meresap ke dalam tanah. Berdasarkan perhitungan curah hujan didapat bahwa besar curah hujan dalam satu tahun sebesar 54.56 m3/detik dan yang meresap hanya 5.37 m3/detik atau 9.84 %. Hal ini menunjukkan bahwa jenis tanah di sekitar wilayah penelitian berjenis lanau dan clay, sehingga mempunyai angka pori yang kecil. Dengan kondisi tersebut maka wilayah tersebut dapat diprogramkan dengan membuat folder-folder tampungan, sumur-sumur resapan, lubang-lubang biopori dan lainya.

Abstract

Solok Regency irrigation network planning which has an area of irrigation land of 3738 ha. The main canals are spread in several areas, namely 43 Irrigation Channels, 17 Dams, 7 Reservoirs and 2 lakes which are still functioning in Solok Regency. The poverty rate in Solok Regency is still quite high, reaching 27,487%. The data includes secondary data on 10-year rainfall data from Kayu Aro, Bayur Maritime Bay Methodology, Padang Panjang Geophysics and 10-year climatology from Kayu Aro Climatology Station. The calculation method used is the intensity of the issen rainfall method, Evapotranspiration of the modified Penman method, the reliable discharge of the DR.FJ Mock method, the cropping pattern, and the need for irrigation water.  The most efficient and optimal planting pattern obtained is PADI-PADI-CORN with large irrigation water requirements in tertiary plots (NFR tertiary plots) ranging from 0 - 1,546 ltr / sec / ha with a maximum of 1,546 ltr / sec / ha in September II, whereas Irrigation water demand in the intake (DR intake) ranges from 0 to 2,378 ltr sec / ha with a maximum of 2,378 ltr / sec / ha in September II. The mainstay discharge available in the Pauh Tinggi Irrigation Network Planning is very abundant with the mainstay discharge (Q80) for irrigation, the maximum mainstay discharge (Q80) occurs in April I with 10.482 ltr / sec / ha and minimum in December II with 3,930 ltr / sec / ha. Based on the mainstay discharge results above it can be stated that the water balance / water balance between the mainstay discharge Q80 and the need for irrigation water experienced a large surplus.

Abstract

Palm fibers are natural fibers that are difficult to rot because there is no decomposer that can decompose the fibers. In addition, in Indonesia there are a lot of palm plants where the fibers are taken from the tree. The charcoal briquette powder is the fine grains of briquette charcoal that is mashed and contains silica. This study aims to determine the effect of using palm fiber as an added material for fiber and charcoal briquette powder as a substitute for cement in the concrete mixture on the compressive strength of concrete. This study uses a mixture of palm fiber as much as 0.75 %, 1.50 %, 1.75 % and 2.75 % from the weight of fine aggregate, as well as charcoal briquettes powder 5 %, 5 %, 10 %, and 15 % of the weight of cement. The compressive strength test was carried out on the 7th, 14th, 21st, and 28th days. The highest compressive strength value was obtained in variation V.2 with a mixture of 2.75% palm fiber + 5% briquette charcoal powder on the 21st day of testing of 20.02 Mpa
