Abstract

Forest destruction may affect forest hydrological functions either as a water regulator, maintaining the timing and distribution of river water flows, maintaining microclimate, or being able to protect the underlying areas from disasters such as floods. Revegetation is considered as an effort to improve the condition of forest and environment. The objective of this study was to examine the hydrological characteristics of soil under stands of Pinus (Pinus merkusii), Ugandan Mahogany (Khaya anthoteca), and Merawan (Hopea odorata Roxb). The method used is periodic measurement of soil physical variables. Our investigation reveals that hydrological and physical properties of soil under the stands were different. Within the same depth of soil, water content changed from the highest to the lowest in Pine (3.05%), Merawan Siput Jantan (2.40%), and African Mahogany (1.89%), respectively. The highest infiltration was 116.25 cm hour-1 under Pine stand, while the lowest was 24 cm hour-1 under Merawan Siput Jantan stand. The highest permeability was 13.27 cm hour-1 under Pine stand, while the lowest was 2.72 cm hour-1 under Merawan Siput Jantan stand. Dominated by clay, the soil texture was relatively similar in each stand. Further, the soil under the three stands were categorized as the soil hydrological group B.

Abstract

Kondisi DAS Cisangkuy mengalami degradasi yang ditunjukkan dengan semakin seringnya kejadian banjir di musim hujan dan kekeringan di musim kemarau. Beberapa kecamatan di Kabupaten Bandung mengalami banjir tahunan. Pada 2013, banjir setinggi dua meter menyebabkan Kabupaten Baleendah terisolasi. Perubahan penggunaan lahan di DAS Cisangkuy merupakan salah satu penyebab menurunnya kondisi hidrologis. Peningkatan populasi di DAS Cisangkuy menyebabkan peningkatan permintaan air. Perubahan penggunaan lahan dan peningkatan populasi dapat mengancam ketersediaan air baku di DAS Cisangkuy. Tujuan dari penelitian ini adalah untuk menganalisis keseimbangan pasokan dan permintaan air DAS Cisangkuy dan untuk menganalisis dampak perubahan penggunaan lahan pada respon hidrologi DAS Cisangkuy. Hasil penelitian menunjukkan bahwa ketersediaan air DAS Cisangkuy dengan debit rata-rata 2015 memiliki jumlah air yang tersedia hingga 343,121,970 m3. Total ketersediaan air hingga 11,104,629,178 m3 pada tahun 2015. Berdasarkan hasil ini, ada defisit air hingga 10,498,001,277 m3 tahun-1.

Abstract

Loss of nutrients through surface runoff and erosion carried from agricultural land, is a major cause of agricultural land degradation. The purpose of this study was to analize nutrients loss from oil palm plantation caused by erosion. This study was carried out using erosion plots measuring 12 m x 3 m consisting a combination of two factors: type of oil palm inter-row and slope. Surface runoff and erosion values in the active inter-row was higher than those in death inter-row. The nutrients loss of N, P, and K from soil eroded in active inter-row were respectively 0.04; 0.11 and 0.10 ton ha-1 year-1. The total nutrient losses (N, P, K) in dead inter-row were 0.007; 0.024 dan 0.023 ton ha-1 year-1.

Abstract

Daerah irigasi (D.I.) Cikeusik dibangun pada tahun 1883 dan mulai beroperasi pada tahun 1884, namun saat ini sudah tidak beroperasi secara optimum. D.I. Cikeusik terletak di Kecamatan Cikeusik, Kabupaten Pandeglang, Provinsi Banten. Sektor pertanian yang terdapat di daerah tersebut memiliki potensi yang sangat baik. Kecamatan Cikeusik mempunyai lahan pertanian seluas 650 ha. Jaringan irigasi di D.I. Cikeusik mencakup jaringan irigasi teknis yang memiliki sembilan buah pintu sadap. Saat ini irigasi Cikeusik mengalami perubahan dalam pemasokan air ke petak tersier, air yang dipasok tidak tercukupi. Penelitian ini bertujuan untuk mengevaluasi kinerja D.I. Cikeusik. Metode yang digunakan dalam penelitian ini adalah menggunakan petunjuk pelaksanaan gabungan penilaian kinerja sistem irigasi utama dan tersier kementerian PUPR 2017. Hasil penelitian menunjukkan bahwa Nilai Kinerja Sistem Irigasi (NKSI) sebesar 64.86% termasuk kategori kinerja irigasi masih kurang.

Abstract

Land use change in the plantation expansion can potentially cause soil degradation leading to drought in the dry season and flooding in the wet season. Hydrological model is important to simulate impact of land use change in the plantation on the discharge fluctuation. This study used MAPDAS Model for simulation purpose. MAPDAS Model uses 4 (four) main simulation input parameters, which are runoff coefficient (Kr), lag time, hydrographic network flow rate, and slope flow rate. The objective of the study are 1) to examine the accuracy of the model in 3 effective-rainfall determination method; 2) to study the hydrology characteristics of micro-watershed dominated by oil palm plantation using MAPDAS Model with 3 effective rainfall determination scenarios. The result showed that the use of MAPDAS Model with rainfall input based on Kr, infiltration index (F), and SCS-CN method gave value of runoff coefficient ranged from 12 to 70%. The MAPDAS Model is able to simulate hydrological characteristics with good result, shown by the CE value which is more than 0.7. catagorized as high to very high accuracy.

Abstract

Dryland farming provides a promising opportunity in increasing agricultural production in rural areas. But, the lack of available water during dry season poses a problem in developing dryland farming. An effective water conservation technique should be developed to alleviate this problem. The use of a small farm reservoir (embung) can be considered as one viable option for such conservation techniques. The purpose of this research was to study the effectivity of small farm reservoirs to supply irrigation water for horticulture commodities. Two different types of small farm reservoir (SFR) were constructed in the micro catchment for the research, i.e. a) SFR built with concrete, b) SFR built without concrete. SFR built with concrete had higher water available for irrigation, which is 34% higher compared to SFR without concrete. In addition, the empirical equation that was used in this research was quite reliable in predicting colected water in the SFRs. Using 80% monthly rain probability, on average one small farm reservoir with dimension 8 m x 2m x 2 m was able to supply irrigation water for 100 m2 horticulture plants for the whole growing period. Keywords: Small farm reservoir, dry season, irrigation, dryland farming.

Abstract

Jatiluhur DAM is one of the multipurpose DAMs in West Java with the design of hydroelectric power plants, water supply in industry, irrigation, fisheries, tourism and flood control. Based on the final report of Juanda Public Corporation in 2000 that the DAM volume in 1964 was 2,970 million m³, in 1987 it was 2,556 million m³, 1995 was 2,456 million m³ and in 2000 was 2,448 million m³. This shows that the DAM volume has decreased by 522 million m³ over a period of 36 years at an altitude of ± 107 masl. The purpose of this study are to calculate sedimentation in the Jatiluhur DAM in 2018. TSS measurements using SNI 06-6989.3-2004 and calculation of sedimentation using direct measurement methods. The results showed that the total sediment in DAM inlet is 859,368.40 tons year-1 and the reservoir outlet is 92,553.33 tons year-1. Based on this data, the total sediment deposited in the Jatiluhur Reservoir in 2018 was 766,815.07 tonnes. So it needs handling in reducing sediment so that the reservoir does not experience silting.
