Hikmah et al, 2017. Characterization of Agronomic Traits on Two Rainfed Rice Varieties on Several Levels of Nitrogen Fertilizers and Water Treatments. JLSO 6(2):176-184.Rainfed rice varieties are expected to increase yield on rainfed fields. This research aim was to identify various agronomic characters including yield of rainfed rice varieties. It was conducted at the Sukamandi Field Station at rainy season 2016/2017, using a split split plot design with 4 replications. Water management as the main plot with two levels (I1: irrigated and I2: rainfed). Nitrogen (N) fertilizer dosage as subplot with three levels (P1: 0 kg N/ha, P2: 60 kg N/ha, and P3: 120 kg N/ha) and varieties as subplots with two levels (V1: Inpari 39 Tadah Hujan Agritan and V2: Inpari 41 Tadah Hujan Agritan). The results showed that water treatment and N dosage on each variety gave different response on their agronomic characters, including yield. Tiller numbers per hill was strongly influenced by water management and dosage of N fertilizer. In irrigated treatment, tiller number increased linearly increasing N dosage. In rainfed,Inpari 41 Tadah Hujan Agritan reach maximum tiller number with 80 N kg/ha which more efficient than Inpari 39 Tadah Hujan Agritan with 91,97 N kg/ha. Rice yield was significant effected by N fertilizer and the genetic trait of each variety. The yield of Inpari 41 Tadah Hujan Agritan was higher than the Inpari 39 Tadah Hujan Agritan. Inpari 41 Tadah Hujan Agritan reached 5.70 t/ha GKG and Inpari 39 Tadah Hujan Agritan 4.62 t/ha.

Abstract

ABSTRAK PERKIRAAN PARTISIPASI INDUSTRI NASIONAL DALAM PEMBANGUNAN PLTN HTR. Salah satu aspek penting dalam penyiapan infrastruktur pembangunan PLTN adalah aspek keterlibatan industri nasional. IAEA memberi rekomendasi bahwa perlu dilanjutkan untuk persiapan fase 2, yakni dengan aspek kebijakan penetapan tingkat partisipasi nasional. Tujuan kajian ini adalah memperkirakan tingkat partisipasi nasional dengan mengetahui tingkat kandungan komponen dalam negeri untuk reaktor tipe HTR berdaya kecil. Metodologi yang digunakan adalah studi literatur, membandingkan hasil kajian potensi industri nasional untuk sistem teknologi PLTN tipe LWR  dengan tipe HTR, melakukan perhitungan perkiraan tingkat partisipasi industri nasional berbasis biaya modal atau investasi yang lingkupnya dibatasi untuk jenis PLTN tipe HTR berdaya kecil dan hanya untuk proyek pembangunan unit pertama. Hasil studi menunjukkan bahwa dibandingkan dengan untuk pembangunan PLTN tipe LWR berdaya menengah hingga besar, tingkat partisipasi nasional dalam pembangunan PLTN diperkirakan sebesar 30%, namun bila dibandingkan dengan pembangunan PLTN tipe HTR berdaya kecil, tingkat partisipasi nasional sebesar 36% (kontrak putar kunci) dan sekitar 38% (kontrak Multi-Package).berdasarkan hal ini, direkomendasikan untuk memilih tipe kontrak putar kunci, hal ini mengingat belum ada pengalaman dalam membangun PLTN. Kata kunci: partisipasi industri nasional, HTR, daya kecil ABSTRACT ESTIMATION OF NATIONAL INDUSTRI PARTICIPATION ON HTR CONSTRUCTION.

Abstract

Potential exploitation of Ingas (Cokro) water resource is currently less than optimal, there are still manywasted water flows and there is still no coordination in planning. The objective of this research is to reviewwater resource potential integratedly, by measuring the spring discharge in real terms, analyzing the utilizationof water source and water balance. The method used in this thesis is by measuring the discharge using currentmeter, analyzing water requirements for plants using Penman method, and analyzing data with the help ofMicrosoft Exel. It is resulted that the total potential of Ingas (Cokro) water resource is 1297 l/dt, utilized fordrinking water (PDAM Surakarta) at 400 l/dt, drinking water for Cokro Village at 4 l/dt, and the remainder isused for irrigation and moving a turbine with 50 Watt electric power. Water demand for irrigation is 995 l/dt,fullfilled from Ingas (Cokro) source discharge at 593 l/dt plus surface water discharge as a result frommeasurment of pulsur river (Plosowareng weir) at 696 l/dt, from the total water resource potential of 1289 l/dt.Water balance of Ingas (Cokro) water resource has already balanced or optimal, while residual discharge of294 l/dt is obtained at measurement point (Plosowareng weir)

Abstract

A low carrying capacity of drainage basin or watershed may cause several problems, where floods occur inrainy season and droughts occur in dry season, also the occurrence of erosion, sedimentation and so on, hasbeen government’s problem in watershed management all along. In order to anticipate this condition,characteristic data of a watershed are required, so that it can be used as basic reference of watershedmanagement.The purpose of this paper is to conduct a study on the characteristics of Tuntang watershed of Central JavaProvince and watershed management model.The method of approach uses aspects of watershed geomorphology such as the shape of watershed, elongationratio and circularity ratio approaches, order of river using Strahle method, watershed density using Lynsleyformula, and river gradient calculated based on the comparison between elevation difference and length of mainrivers.Results show that magnitude index of Tuntang Sub watershed has elongated shape with Rc value between 0.27 to0.46, which means that the longer concentration time needed, the lower flood fluctuation. And relatively roundedshape with Rc value between 0.57 to 1.00, which means that the shorter concentration time needed, the higherflood fluctuation occurs. Sub watershed order range from 4 to 6 order, which means that river basins have floodwater level increase (moderately quick to fast), likewise water level decrease. Level slope between 0 - 8 % (lowflow velocity) with an area of 117605.56 Ha, and very steep slope > 40 % (very high flow velocity) with an areaof 4219.09 Ha. The highest drainage density occurs in Sub watershed of Tuntang downstream 1.88 Km / Km²,and lowest Sub watershed of Blorong 1.01 Km / Km². Based on both magnitudes, the water being stored is inmedium category and floods and droughts occur. The flow pattern has the shape of rectangular dendritic anddendritic medium, showing that soil characteristics is limestone and shale. To obtain optimal performance resultof Tuntang watershed, integrated watershed management program is needed in watershed managementintegration by involving various associated parties.
