Alternative Assessment of Urban Flood Management Using Eco Drainage Approach (Case Study: the Area of the Terminal Payung Sekaki )

The area of the Terminal payung sekaki in the future directed by function area of Commerce (business), the ground transportation center and the main entrance gate Pekanbaru city by land for the constellation of the most prestigious regional and city of Pekanbaru in particular. Land conversion happens on the open land into developed regions an impact on the improvement of storm water runoff and impairment infiltration or water storage amount that goes into the ground. Eco drainage is drainage infrastructure of urban areas where rainfall runoff is not directly channeled water receiver but accommodated in the retention pond to provide sufficient time for the water to seep into the ground. Retention pond is designed not only as flood control but also as a place of recreation for the park to be combined with increasing the area of green open space and improve the esthetic value of theenvironment. The completion of this study using EPA SWMM 5.0 assistance program to analyze the suitability of the drainage capacities to cope with the flood problem. The results showed that the problem of flooding due to the capacity of the existing channel with a dimension of 1x1 m not in accordance with the conditions of rain and runoff into drainage capacities with a value of 1.0 or 100% has been filled with runoff that goes into the drainage. Simulation repairs done by using the channel dimensions 2x2 m still not able to cope with the recent flooding. The capacity of the existing line with the percentage Impervius undeveloped land with a value of 85%, 60% and 2% can be maximized by the addition of the retention pond with an area of 2 hectares and a depth of 2 m as well as changes in the dimensions of the channel just upstream (3x3m) and downstream (2x2m) into alternative solutions to problems ofurban flooding in the region. The capacity of drainage channels and retention ponds planned until the 20 years in the future development of the city of pekanbaru RTRW according to changes in the percentages of land be impervius 95% still holds a runoff into drainage channels so that the problem of flooding in the area of AKAP Subdistrict payung sekali can be resolve

VALUE ADDED ANALYSIS OF SWEET POTATO CHIPS PROCESSING IN JEMBER REGENCY

The Food security has become an important issue in Indonesia. One of the processing industries that can support food security is the sweet potato industry. The purpose of this study is to calculate the added value of sweet potato chips. Data acquisition in this study was obtained by observation and interviews. The study was conducted in April-July 2019. This study is using descriptive data analysis method to describe the processing of sweet potatoes into sweet potato chips. In this study also used quantitative analysis to determine the added value of sweet potato by using Hayami method. The results of this study are expected to encourage the development agroindustry based on local commodity, especially sweet potatoes, to support food security

Pengaruh Pupuk Kandang dan Konsentrasi Urine Kelinci terhadap Pertumbuhan dan Hasil Tanaman Mentimun (Cucumis Sativus L.)

Kondisi lahan pertanian di Indonesia semakin mengalami kerusakan, salah satunya diakibatkan oleh perilaku petani yang lebih menggunakan pupuk anorganik dibandingkan pupuk organik. Penelitian ini bertujuan untuk mengetahui respon pertumbuhan serta hasil berbagai macam pupuk kandang dan konsentrasi urine kelinci terhadap tanaman mentimun. Penelitian ini dilaksanakan pada Januari - Maret 2021 di Desa Wanantara, Kecamatan Sindang, Kabupaten Indramayu. Penelitian ini menggunakan percobaan faktorial, dirancang menggunakan Rancangan Acak Kelompok Lengkap (RAKL) 2 faktor yang diulang sebanyak 3 kali. Faktor pertama, macam pupuk kandang yang terdiri atas 3 taraf yaitu pupuk kandang sapi, pupuk kandang kambing, pupuk kandang ayam. Faktor kedua, konsentrasi urin kelinci yang terdiri atas 4 taraf yaitu 0 ml/l, 100ml/l, 200ml/l, 300ml/l. Data dianalisis menggunakan analisis sidik ragam (Anova) dengan taraf 5%. Uji lanjut perlakuan dilanjutkan dengan DMRT taraf 5%. Hasil percobaan menunjukkan adanya interaksi pada parameter panjang sulur 1 MST rerata 10,89 cm dan 2 MST rerata 28,66cm. Perlakuan pupuk kandang ayam memberikan hasil yang berbeda nyata terhadap panjang sulur 3,4 MST rerata 72,24cm; 83,25cm, diameter batang 1,2,3,4 MST rerata 3,96mm; 6,32mm; 8,14mm; 8,61mm, jumlah daun 1,2,3,4 MST rerata 5,19 helai; 7,22 helai; 12,06 helai; 12,30 helai, jumlah bunga rerata 4,50 buah, panjang buah rerata 12,56 cm, bobot buah per buah rerata 128,57 gram, bobot buah per tanaman rerata 1324,33 gram, bobot segar tanaman rerata 49,92 gram, dan bobot kering tanaman rerata 22,17 gram. Perlakuan 300 ml/liter memberikan hasil berbeda nyata terhadap diameter batang 1 MST rerata 3,84mm dan bobot buah per tanaman rerata 1197,67 dengan produksi mencapai 1104,61 gram/polybag atau 60,8 ton/ha
