The main campus of UNS Surakarta, occupies an area of ± 59,211 Ha. At present, the problem faced by UNS is the increasing of narrow green space, so that it increases rain water and lead to runoff. This process has an impact on the increase in flood discharge and the reduction in the supply of rainwater which becomes ground water reserves. In order to realize a Green Campus that supports sustainable development, efforts have been made relating to groundwater and surface water management. A total of 117 infiltration wells and more than 500 biopori infiltration units have been built, which serve to increase shallow groundwater reserves so that it increases rainwater harvesting and soil moisture. Rainwater that cannot be accommodated in infiltration wells is channeled to the lake named Danau UNS which has an area of 1,206 Ha with a maximum water volume of ± 7,959 m3 , so that it is expected to be able to maintain the shallow ground water balance at the Kentingan UNS Campus. In the future planning, Universitas Sebelas Maret will improve domestic wastewater treatment for other uses, so that there is an efficient use of sustainable clean water

Curve Method

The Battered Pile  is one of the foundation designs that aims to increase the lateral bearing capacity of the foundation. Battered Pile are designed with a certain slope that aims to increase the lateral capacity of the soil. The type of soil used will affect the lateral capacity of the pole. Calculation of bearing capacity of the pile is carried out on the condition of clay and sand soils at slope 00 to +200. The calculation results will then be analyzed to understand the effects that occur. The calculation results will be presented in the p-y curve method. The use of this method is expected to make it easier to understand the characteristics of Battered Pile for soil conditions. Based on the analysis it was found that an increase in the  capacity of the pile up to 23% in the slope of 100 to 150. Sand soil in conditions below the surface of the ground water will have a linear carrying capacity and have a lower deflection value when compared to clay soil at a depth of 2 meters. But at a depth of 16 meters, clay has a point where it has a lower deflection value compared to sandy soil.AbstrakTiang pancang Battered Pile merupakan salah satu rekasaya fondasi yang bertujuan untuk meningkatkan daya dukung lateral fondasi. Tiang Battered Pile dipancang dengan kemiringan tertentu yang bertujuan untuk meningkatkan daya dukung lateral tanah. Jenis tanah yang digunakan akan mempengaruhi daya dukung lateral tiang. Perhitungan daya dukung tiang dilakukan pada kondisi tanah lempung dan tanah pasir pada kemiringan 00 hingga +200. Hasil perhitungan kemudian akan dianalisis untuk memahami pengaruh yang terjadi. Hasil perhitungan akan disajikan dalam metode p-y curve. Penggunaan metode ini diharapkan dapat memudahkan dalam memahami karakteristik tiang Battered Pile terhadap kondisi tanah. Berdasarkan analisis didapatkan bahwa terjadi peningkatan daya dukung tiang hingga 23% pada kemiringan 100 hingga 150. Tanah pasir pada kondisi di bawah permukaan air tanah akan mengalami kenaikan daya dukung secara linier  dan memiliki  nilai lendutan yang lebih kecil jika dibandingkan dengan tanah lempung pada kedalaman 2 meter. Tetapi pada kedalaman 16 meter, tanah lempung memiliki titik dimana memiliki nilai lendutan yang lebih kecil jika dibandingkan dengan tanah pasir.

<p class="1Body">Water is an important good provided by watersheds and is critical in sustaining life and socio-economic development. This study evaluated water provision in the Chyulu Hills watershed which is one of the important dry land water catchments in Kenya. Surface water discharge was mainly through rivers and springs with the latter being more prevalent than the former while ground water provision was primarily through boreholes and shallow wells. Springs discharged the highest water volume annually estimated at 128.14million m<sup>3</sup> or 85.14% of all the water discharged in the watershed, with shallow wells and boreholes discharging the least water. For all the springs found in the watershed, Mzima springs discharged the highest water volume estimated at nearly 113.15 million m<sup>3</sup> annually or 88.30% of the water produced by all the springs; and about 75.19% of the water in the entire watershed. Rivers which were active had a total water discharge of about 20.66million m<sup>3</sup> per year, with Kibwezi River discharging 17.59 million m<sup>3</sup> annually or 85.14% of all the water from rivers. Shallow wells were mainly prevalent at Nthongoni and the Makindu, and their annual water discharge was about 16.96million m<sup>3</sup> per year with boreholes contributing 98.87% (approximately 16.76 million m<sup>3</sup>/yr.) of the ground water, and the rest (19,169.92m<sup>3</sup>/yr.) being contributed by shallow wells. The total amount of water discharged in the watershed by the combined water source types was about 150.49 million m3/yr.</p>

The effectiveness of zakat management in Indonesia can be seen from how far the zakat funds can be collected and properly distributed to the right people (mustahiq) by the zakat management agencies. This study aims to determine the extent of the collection, management, and distribution of zakat and its effect on the efficiency of zakat distribution by the National Zakat Agency in the 2008-2019 periods. This research uses the combination of qualitative and quantitative research, which the data source refers to the annual financial report of the National Zakat Management Agency in the 2008-2019 periods. Analysis of the Data uses the descriptive-qualitative and statistical-quantitative through correlation and linear regression tests. The results of this study show: first, the regulation of zakat has not been fully implemented in practice, so that the distribution of zakat has no positive and significant effect on the efficiency of zakat distribution; second, the role of zakat management institutions has no significant effect on the efficiency of zakat distribution in Indonesia; and third, the distribution of zakat and the role of zakat management institutions have no simultaneously positive and significant effect on the efficiency of zakat distribution in Indonesia, which is shown through the results of the significance test (F test) and the coefficient of determination test, as evidenced by the calculation results of the determination test only 19.1%, while the remaining 80.9% are other factors that are not studied. The implication of the results of this study is the management of zakat management must be improved so that its distribution becomes more effective and efficient.
