Abstract

The Batang Kuranji watershed is an area that plays a vital role in the water resources preservation and conservation in Padang city. However, recently the sustainability of these water resources has suffered hydrologically, marked by a sharp fluctuating flood discharge. This study aims to measure the water resources sustainability in the Batang Kuranji watershed. The method used in this research is Nedbør Afstrømnings Model (NAM) modeling and an integrated approach. The results of NAM showed that the most prominent parameter values ​​are TIF (0.9), TG (0.965), CK1 (0.23), and CK2 (1.1), which indicate an infiltration transformation in this watershed. The integrated analysis showed that deforestation and population growth are the main factors for this issue, and the land-use conversion also affected these problems. Reducing the population growth rate, evaluating the urban development, reforestation, and improving water infrastructure along rivers-side will reduce the risk of watershed damage and maintain its sustainability.

Abstract

A study about the effect of tree architecture on canopy throughfall and stem flow was conducted upstream of Batang Mahat River Basin, Lima Puluh Kota Regency, West Sumatra, Indonesia. Four dominant tree species in the location, Voacanga foetida, Guioa sp, Schima wallichii and Rhodoleia champonii, were selected and represented in architecture by Scarrone, Schoute, Rauh and Leeuwenberg, respectively. Furthermore, the sample was three trees of each species. The throughfall canopy was measured using a 1 x 1 m plastic plot placed at the edge, while the stem flow was calculated by two meters plastic tube with a five-litre tank at the bottom. These data were collected eight times over one month. The study aimed to the analyzed relationship between tree architecture and canopy throughfall and stem flow upstream of the Batang Mahat River Basin. The result showed that Schima wallichii differed significantly in throughfall canopy relative to the other three species. Additionally, V. foetida significantly differed in stem flow compared to the other tree species. There was no correlation between throughfall canopy, stem flow and precipitation, but the two parameters were affected by three architectures. These findings are useful for soil and water conservation in the upper Mahat River Basin.

Abstract

Agriculture traditionally still uses large areas of land with relatively large amounts of water. The application of solar energy is one of the uses of new and renewable energy. This research uses a 50 Wp photovoltaic cell, battery, solar charge controller, DC stepdown, DC pump and hydroponic frame. The stages of the research are the design of the tools, the calculation of the power required by the tools, the manufacture of the tools, the collection of data and the analysis of the data. The data collected is temperature, sunlight intensity, electric power, electrical energy, water discharge, and photovoltaic efficiency. The data were processed and analyzed in an exploratory manner. Based on the results of the research conducted, the lowest average temperature was 25.33 C and the highest was 33.70 C with the highest average light intensity of 920.26 w/m2 at 12.00 WIB. The relationship between temperature and light intensity with a value of R2 of 0.7594. The highest average electrical energy obtained by polycrystalline is 30.44Wh. The water lost from the hydroponic system is 0.03%. The efficiency of photovoltaic cells is 10.09%–15.72%.         Keywords:  DC pump, hydroponics, light intensity, photovoltaic

Abstract

Abstrak. Kebutuhan air semakin meningkat, maka air dari sisi ketersediaan perlu dikelola serta diatur sesuai dengan kebutuhan, sehingga air dapat dimanfaatkan dan didistribusikan jika diperlukan. Salah satu permasalahan yang mendasar di Indonesia pada sektor pertanian adalah ketersediaan air. Air terbatas dalam jumlah dan waktu juga ruang serta letak sumber air yang lebih rendah dari lahan pertanian. Terkait tingginya kebutuhan air tersebut, pemanfaatan teknologi yang mampu mengangkat dan mengalirkan air dari sumbernya ke lahan-lahan pertanian serta hunian penduduk sangat dibutuhkan, salah satu teknologinya adalah pompa. Penelitian ini bertujuan untuk melakukan rancang bangun pompa sistem wheel spiral sebagai inovasi untuk irigasi.Pengujian dilakukan 3 kali ulangan dengan lama waktu 1 jam dengan RPM 6,917 ± 7,83, kecepatan sudut 0,72 ± 0,77, daya poros 0,25 ± 0,27 Watt, debit air tertampung 0,0001533 ±0,0001732 m3/s, energi kinetik 0,36 ± 0,42 Watt, dan rata-rata efisiensi pompa 67,85 %. Tinggi maksimum pengeluaran yang dapat dicapai oleh pompa adalah 1,52 m. Pompa ini bisa menaikkan air lebih tinggi dari sudu-sudu tertinggi pada kincir serta efisiensi yang dihasilkan cukup besar sehingga dapat digunakan untuk mengairi lahan yang berada diatas sumber air. Design Of Pump With Spiral Wheel System For Small ScaleAbstract. The needs of water is always increase, the available water have to manage and control by human as a needed. Water can be used and distributed if it needs. One of the basic water’s problem in agriculture sector is the field capacity of water. Water is limited in quantity, naut and the water position is lower than the land. Thinking about the high need of water, it is important to use technology to rise and distribute the water from the reservoir to lands and also to living live. One of the technology is pump. This research was conducted to design a pump without machine as a new invention for irrigation. This research is about one hour with 3 times repeatation RPM 6,917 ± 7,83, angle velocity 0,72 ± 0,77, axis power 0,25 ± 0,27 Watt, accomodated rate of flow 0,0001533 ± 0,0001732 m3/s, kinetic energy 0,36 ± 0,42 Watt, and rate of pump efficiency 67,85%. The maximum high of output can reached by the pump is 1.52 m. This pump can rise water higher than the highest goosebeak on waterwheel and the efficiency is highest than the waterwheel. So, it can be used to irrigate the lands that position is above the water.

Abstract

Each region has its own cropping pattern due to its particular characteristics. Crop production may be increased by adjusting the timing of planting. Remote sensing technologies can be used to monitor regions where planting occurs simultaneously. The purpose of this study is to assess the degree of uniformity at the beginning of the paddy cultivation season in West Sumatra. In each growing season, there are two early cultivation seasons in the West Sumatra province. 19% of the region started cultivation in the first period of the first cultivation season (CS1), and 81% in the second period. 4.2% of the region started cultivation in the first period of the second cultivation season (CS2), while 95.8% started planting in the second period. 35% of the region started planting in the first period of the third cultivation season (CS3), while 65% started planting in the second period. The level of uniformity at the beginning of the second cultivation season was higher than at the beginning of the first cultivation season
