Abstract

Abstrak Sektor pertanian masih merupakan primadona masyarakat dan dijadikan sebagai pekerjaan dalam menunjang kehidupan, meskipun banyak kawasan pertanian yang beralih fungsi menjadi pemukiman terutama di perkotaan. Hampir setiap tahun, luas panen mengalami penurunan. Untuk mengantisipasi hal tersebut, pemerintah dan pemerintah daerah telah banyak membangun infrastruktur keairan, terutama bendung dan bendungan. Daerah irigasi Citanduy dengan luas layanan 427 hektar merupakan salah satu daerah irigasi di Kota Tasikmalaya, sehingga sangat rentan terhadap alih fungsi lahan persawahan menjadi pemukiman. Ketersediaan air sangat penting dalam pemenuhan areal pertanian. Penelitian ini dilakukan untuk mengetahui debit andalan di DAS Citanduy-Sirnagalih seluas 474,65 km2. Terdapat 2 pos curah hujan yaitu Cigede dan Tejakalapa selama sepuluh tahun dari tahun 2009 hingga 2018. Curah hujan rata-rata bulanan dihitung dengan metode Thiessen dengan proporsi luas pengaruh adalah 0,4 dan 0,6. Evapotranspirasi dihitung menggunakan metode Penman-Monteith, dan pemodelan debit menggunakan metode NRECA. Pos duga air Asta-Cikunir digunakan sebagai acuan dalam menentukan parameter kalibrasi yaitu PSUB, GFW, dan tampungan air tanah awal dengan nilai 0,8, 0,29: 100, serta nilai NSE 0,719. Debit andalan Q80 adalah 17,4 m3/s. Debit andalan adalah ketersediaan air di daerah irigasi Citanduy. Berdasarkan debit andalan ini, musim tanam I dan II masih dapat dilakukan secara bersamaan. Kata kunci: debit andalan, kalibrasi, NSE, sungai Citanduy   Abstract The agricultural sector is still the prima donna of the community and is used as a job to support life. However, many agricultural areas have been converted into settlements, especially in urban areas. Almost every year, the harvested area has decreased. To anticipate this, the government and local governments have built a lot of water infrastructure, especially weirs and dams. The Citanduy irrigation area with a service area of 427 hectares is one of the irrigation areas in the City of Tasikmalaya, so it is very vulnerable to the conversion of rice fields into settlements. The availability of water is crucial in fulfilling agricultural areas. This research was conducted to determine the mainstay discharge in the Citanduy-Sirnagalih watershed covering an area of 474.65 km2. There are two rainfall posts, namely Cigede and Tejakalapa, for ten years from 2009 to 2018. The average monthly rainfall is calculated by the Thiessen method, with the proportion of the area of influence being 0.4 and 0.6. Evapotranspiration was calculated using the Penman-Monteith method and discharge modeling using the NRECA method. The Asta-Cikunir water gauge post is used as a reference in determining calibration parameters, namely PSUB, GFW, and initial groundwater reservoirs with values of 0.8, 0.29: 100, and NSE values of 0.719. The Q80's dependable flow is 17.4 m3/s. The mainstay of debit is the availability of water in the Citanduy irrigation area. Based on this reliable discharge, planting seasons I and II can still be carried out simultaneously. Keywords: dependable flow, calibration, NSE, Citanduy river

Abstract

Roads are important in the distribution of goods in the industrial sector. Good roads can speed up the distribution process from one area to another. On the other hand, if the road conditions are bad, it will certainly slow down distribution in the area. Therefore, road damage conditions can affect the economic sector in the area. There are many factors that cause damaged road conditions, one of which is the volume or load of vehicles that exceeds the capacity of the road. The impact of road damage will certainly disrupt the comfort and safety of road users. This research was carried out using a survey method, directly observing the condition of road damage and distributing questionnaires to road users. Then the test is processed with Validity Test, Reliability Test, Mean Value and Standard Deviation. Based on the findings, the types of damage were Crocodile Skin Cracks, Longitudinal Cracks, Potholes and Bleeding. Then, based on the distribution of the questionnaire, all statement items are declared valid and reliable. Then, based on the mean value, it is obtained that the accident factor is the aspect that most influences the safety of road users. The road flooding factor is the aspect that has the most influence on comfort. Then the delay factor is an aspect that influences costs.

Abstract

Pasir Bajing TPA is the only TPA with a Sanitary Landfill system in Garut Regency. The increasing burden of landfills along with population growth makes the feasibility of the Pasir Bajing landfill interesting to study. This research aims to analyze the technical feasibility of the Pasir Bajing TPA and evaluate the feasibility of waste storage buildings in the Sanitary Landfill system at the Pasir Bajing TPA. The research method used is descriptive evaluative. Data obtained directly through field surveys. The technical feasibility of the landfill was analyzed based on SNI-03-3241-1994, while the feasibility of the waste storage building was analyzed using SNI 03-6154-1999. The research results show that the Pasir Bajing TPA technically does not fully meet the requirements according to SNI-03-3241-1994 because there are no monitoring wells, leachate collection buildings, drainage is not yet effective and a new weigh bridge has been built. The evaluation results of the waste storage building show that in terms of dimensions it meets the criteria of SNI 03-6154-1999. Based on the calculation of the capacity of the waste holding building, it is able to accommodate waste for the next 2 years, however, in terms of strength, it is not suitable because the height of the embankment and the height of the embankment or gabions do not match the strength to hold the embankment in the event of a shock or landslide.
