The success of aloe vera as business commodity in co-partnership pattern, like that between PT Kavera Biotech and the collective work cluster (KUB) of aloe vera farmers in Kecamatan Beji, Depok, needs an accurate evaluation. The objective of this research were to (1) investigate the co-partnership business, (2) analyze the feasibility, and (3) analyze the development strategy. The data were collected by observation, interview, and questionnaire. The location selection was done purposively based on the consideration that the location had been used as sampling for aloe vera cultivation. The feasibility of business was valued using the methods of PBP, NPV, BCR, IRR, and BEP. Analysis of enterprise development strategy using the Input Stage (EFE and IFE), Matching Stage (SWOT and IE), and Decision Stage (QSPM). The result of this study showed that the aloe vera business with co-partnership pattern based on Analysis I was feasible to be managed in 6 KUBs; while the one based on Analysis II was feasible to be managed in 5 KUBs. Analysis I on the farmers with house-yard cultivation field or pot cultivation resulted that it was feasible to be managed, while the Analysis II on the farmers in KUB Tanah Baru and Kemiri Muka resulted that they were not feasible to be managed. In the meantime, the aloe vera cultivation in abandon field in KUB Pondok Cina and Tanah Baru were feasible to be managed based on Analysis I and II. The farmers with house-yard cultivation field or pot cultivation in small scale (<100  plants), middle scale (100-199 plants), and big scale (200-399 plants) cultivation and the aloe vera cultivation in abandon field with small scale (300-399 plants), middle scale (400-499 plants), and big scale (>500 plants) on Analysis I and II that it was feasible to be managed. The best result of the development strategies is the need to increase the productivity in utilizing the increasing demand of aloe vera materials.

Design of Water Source Alternative Based on SWAT Model Simulation

Water shortage problem was often happened in many places in Indonesia. Water availability is very important not only for domestic needs, but also for other activities particularly for agricultural activities. To solve water shortage problem, this study aimed to design a water source alternative. The rain is a free water source and collecting rain in the small dam or reservoir is one of the effective rainwater harvesting technique that can increase water availability. This research was conducted at Sekaran Village and the analysis had done using SWAT (Soil and Water Assessment Tools) model. The planned rainfall and discharge were analysed by 5 years return period to calculate the water potential for reservoir charging. The results of this study indicated that the location of the reservoir was planned in a forest area with a slope of 8-25%, on coordinates 111º38'11.39"E and 7º6'14.22"S and has a storage volume of 13737 m3. The reservoir has 4356 m2 surface area with a depth of 3 m. Based on the SWAT model simulation, the highest average discharge potential occured in February with a discharge of 0.312 m3/s and the lowest average discharge occured in October with a discharge of 0.044 m3/s. The total volume of potential annual water that can fill the reservoir is 61.166 m3/s per year based on a planned rainfall of 115.38 mm and a planned flood discharge of 2.54 m3/s with a return period of 5 years. The reservoir construction required a cost of IDR 1,200,747,000

Analisis Kesesuaian Lokasi Bendung Kecil dan Daerah Pemanenan Air Hujan (PAH) dengan Menggunakan Sistem Informasi Geogerafis (SIG) di Wilayah Perkotaan

Assessment of site suitability for water harvesting in Sentul City is an important, because the Sentul City area often problems with water supply and is expected to prediction a water deficit in 2050, other problems are floods often occur in the downstream during the rainy season. This study aims to analyze the suitability of the location for small dam and reservoirs determine the number of small dam and reservoirs that can be built in Sentul City based on location suitability maps. Identifying locations for the construction of small dam and reservoirs can use of Geographic Information System (GIS), the approach used multi criteria analysis and weighted overlay techniques with software ArcGIS. Six criteria were considered for this study, which include topographic factors (slope), land use, soil texture, rainfall, and distance to the river and distance to the road. The multi criteria analysis approach, each criterion was assigned a weight with slope being considered as the most important factor. Weighted overlay analysis was performed in ArcGIS and determination of suitable small dam and reservoir site was done from the summation of weight of each contributing factor. A final suitability map was generated which indicated that 34% of the total study area showed that the area was not suitable, 31% highly suitable, 27% was suitable, 6% was moderately suitable and 2% was low suitable for dam construction. Based on suitable map, 5 (five) samall dam and 9 (nine) reservoir can be used to water harvesting that can be used as raw water sources in Sentul City

Evaluasi Saluran Drainase di Perumahan Alam Sinar Sari Kabupaten Bogor Jawa Barat

Drainage system is one of the important infrastructure components to drain runoff from rainfall. The purpose of this research were to identify the condition of existing drainage system in Alam Sinar Sari Residence, to analyze the discharge using EPA SWMM 5.1 application, and to analyze the suitability of existing drainage system with its runoff. The research was conducted since March 2018 on Alam Sinar Sari Residence which is located in Cibeureum Petir, with the total area of 15 ha. Based on analysis and statistic test, the acceptable distribution model is Log Pearson III model with 5 year return period. The rainfall designed was 175.86 mm. Based on simulation done using SWMM 5.1, the actual debit of conduit C76 were bigger than its planned debit and should be re-evaluated. Conduit C76 had dimension of depth of 0.31 m and width of 0.34 m. Based on simulation the discharge in C76 of 0.088 m3/s was bigger than the planned debit which was only 0.069 m3/s. After evaluation, conduit C76 should undergone changes of width dimension from 0.34 m to 0.50 m to be able to hold runoff.Keywords : designed rainfall, drainage, EPA SWMM 5.1, runof
