    Tujuan penelitian ini adalah untuk mengetahui (1) Pengaruh cara pemeraman yang berbeda terhadap kandungan vitamin C buah pisang Raja (2) Pengaruh lama pemeraman terhadap kandungan vitamin C buah pisang Raja (3) Adanya interaksi antara cara dan lama pemeraman terhadap kandungan vitamin C buah pisang Raja. Penelitian ini dilaksanakan di Laboratorium Biologi IKIP PGRI Madiun pada bulan Juni sampai September 2012. Rancangan penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 2 faktorial yaitu cara pemeraman dan lama pemeraman. Cara pemeraman dibedakan menjadi daun Lamtoro (C1), Karbid (C2) dan Larutan Ethrel (C3), dan faktor lama pemeraman meliputi 0 hari (L0), 2 hari (L1), 4 hari (L2), 6 hari (L3), dan 8 hari (L4). Data penelitian ini dianalisis dengan menggunakan analisis variansi (ANAVA) ganda. Jika dalam penelitian ini didapatkan nilai F hitung > Ftabel berarti hipotesis diterima dan untuk mengetahui perbedaan tiap perlakuan dilanjutkan dengan uji Beda Nyata Terkecil (BNT) dengan taraf signifikansi 5%. Hasil penelitian menunjukkan bahwa: (1) Cara pemeraman yang berbeda berpengaruh terhadap kandungan vitamin C buah pisang raja (Musa paradisiaca L). Pemeraman dengan ethrel menghasilkan rata-rata vitamin C yang paling tinggi yaitu 8,51 mg setiap100mg larutan pisang. (2). Lama pemeraman berpengaruh terhadap kandungan vitamin C pada buah pisang raja (Musa paradisiaca L). Pemeraman pada hari ke-4 menghasilkan vitamin C paling tinggi untuk semua perlakuan yaitu 11,02mg/100mg. (3). Ada interaksi antara cara dan lama pemeraman terhadap kandungan vitamin C buah pisang raja (Musa paradisiaca L). Pada cara pemeraman dengan ethrel dan lama pemeraman 2 hari didapatkan kandungan vitamin C yang paling tinggi dan berbeda nyata dengan perlakuan yang lain

    Education Department Bondowoso District field of education personnel have a duty to analyze of teachers placed needs. This time the field of education personel have a problem to implement analysis of needs teacher placement process among others the length of the process of data collection, and data analysis is still using the manual method. This problem resulted teacher placement needs analysis process takes a long time and error prone. To answer these problems then made an application determining teacher placement needs. Applications made under regulation with five ministers, this application will generate data that shortage or excess school teacher and produce recommendations that can be moved assign teachers. At this stage of the implementation of the application needs analysis the placement of the teachers in primary schools shows conformity with the expectation of 100% and worth to be used. Teacher placement needs analysis process done more effectively and efficiently than ever before. The data used was school data in the academic year 2013 - 201

    Coupled, Physics-Based Modeling Reveals Earthquake Displacements are Critical to the 2018 Palu, Sulawesi Tsunami

    The September 2018, Mw 7.5 Sulawesi earthquake occurring on the Palu-Koro strike-slip fault system was followed by an unexpected localized tsunami. We show that direct earthquake-induced uplift and subsidence could have sourced the observed tsunami within Palu Bay. To this end, we use a physics-based, coupled earthquake–tsunami modeling framework tightly constrained by observations. The model combines rupture dynamics, seismic wave propagation, tsunami propagation and inundation. The earthquake scenario, featuring sustained supershear rupture propagation, matches key observed earthquake characteristics, including the moment magnitude, rupture duration, fault plane solution, teleseismic waveforms and inferred horizontal ground displacements. The remote stress regime reflecting regional transtension applied in the model produces a combination of up to 6 m left-lateral slip and up to 2 m normal slip on the straight fault segment dipping 65∘ East beneath Palu Bay. The time-dependent, 3D seafloor displacements are translated into bathymetry perturbations with a mean vertical offset of 1.5 m across the submarine fault segment. This sources a tsunami with wave amplitudes and periods that match those measured at the Pantoloan wave gauge and inundation that reproduces observations from field surveys. We conclude that a source related to earthquake displacements is probable and that landsliding may not have been the primary source of the tsunami. These results have important implications for submarine strike-slip fault systems worldwide. Physics-based modeling offers rapid response specifically in tectonic settings that are currently underrepresented in operational tsunami hazard assessment

    Comparing Sustainable Performance of Industrial System Alternatives in Operating Conditions

    International audienceLife Cycle Assessment (LCA) is an approach to assess the environmental performance of products throughout their entire life cycle. LCA-based decision-making usually focuses on environmental impacts, excluding other considerations, such as customer expectations and economic aspects. Moreover, although the environmental performances of industrial systems are highly dependent on operating conditions (e.g. local context, accessibility of resources), LCA usually integrates generic data. The aim of this chapter is to provide an integrated framework to identify the solutions best suited to a specific context, considering environmental, economic and commercial aspects.First, the environmental performances of competing products are compared thanks to LCA. A scenario-based approach is then applied based on the most influential parameters identified in the environmental assessment. Costs are then incorporated into a set of exploitation scenarios.Second, several customer profiles are generated with respect to their economic and environmental strategies. Products are then ranked according to these profiles. The final step is to identify the most suitable solution for a given context-client couple. The framework is applied to three burners for forge furnaces. Results show that client profiles and operating contexts (namely client expectations, location and resource availability and costs) affect the technological choices
