PERTUMBUHAN Kappaphycus alvarezii DENGAN PENAMBAHAN EKSTRAK Sargassum aquifolium

Tujuan penelitian ini adalah mempelajari pengaruh penggunaan Sargassum aquifolium dengan konsentrasi dan lama waktu perendaman yang berbeda terhadap pertumbuhan Kappaphycus alvarezii, serta mengetahui pengaruh penggunaan S. aquifolium terhadap persentase kadar karaginan K. alvarezii. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan perlakuan faktorial yang terdiri dari dua faktor yaitu faktor 1 berupa konsentrasi ekstrak Sargassum aquifolium dan faktor 2 berupa perlakuan lama perendaman. Faktor 1 terdiri atas 4 perlakuan konsentrasi perendaman yaitu kontrol (K0), konsentrasi 5% (K1), 10% (K2), 15% (K3). Faktor 2 terdiri atas 3 taraf yaitu lama perendaman 30 menit (T1), 60 menit (T2) dan 90 menit (T3).  Data variabel penelitian dianalisis menggunakan analisis sidik ragam (ANOVA) pada taraf kesalahan 5%. Hasil penelitian menunjukkan bahwa pemberian ekstrak Sargassum aquifolium tidak memberikan pengaruh terhadap pertumbuhan rumput laut Kappaphycus alvarezii. Perlakuan K1T3 (perendaman dengan konsentrasi 5% selama 90 menit) menunjukkan hasil tertinggi dari perlakuan lainnya, nilai laju pertumbuhan spesifik 6.11%, pertumbuhan mutlak 663.89 gram, berat kering 197.80 gr dan nilai kadar karaginan yaitu 53.33%. Berat kering terendah diperoleh pada perlakuan K3T3 (perendaman dengan konsentrasi 15% selama 90 menit). Kesimpulan penelitian ini adalah pemberian ekstrak Sargassum aquifolium tidak memiliki pengaruh nyata terhadap pertumbuhan Kappaphycus alvarezii dan kadar karaginan tertinggi adalah 53.33% terdapat pada perlakuan  konsentrasi ekstrak Sargassum aquifolium 5% dengan perendaman selama 90 menit.Kata Kunci: berat kering, ekstrak, karaginan, perendaman, pertumbuhan.GROWTH PERFORMANCE OF Kappaphycus alvarezii WITH ADDING Sargassum aquifolium EXTRACTABSTRACTThis research purpose is to study the effect of adding Sargassum aquifolium extract dan time of submersion for growth performance and carrageenan content of Kappaphycus alvarezii. This research used completely randomized design with factorial treatment, consist of two factors. The first factor is concentrations of Sargassum aquifolium extract. The second factor is time of submersion. The first factor consist of 4 treatments are control (K0), consentrasion 5% (K1), 10% (K2), 15% (K3). The second factor consist of submersion time of 30 minutes (T1), 60 minutes (T2) dan 90 minutes (T3). Variable datas of this research was analized using ANOVA (Analysis of Variance) at 5%. The result showed that Sargassum aquifolium extract was not significantly affected growth performace of Kappaphycus alvarezii (P0,05). K1T1 (submersion with a concentration of 5% during 90 minutes) showed the higest results from other treatments, specific growth 6.11%, absolute growth 663.89 g, dry weight 197.80 g and carrageenan content 53.33%. The lowest dry weight is K3T3 (submersion with a concentration of 15% during 90 minutes). The conclusion are Sargassum aquifolium extract did not have any real effect on performance growth of Kappaphycus alvarezii and the highest levels of 53.33% carrageenan contained in the treatment Sargassum aquifolium extract concentration of 5% with submersion time of 90 minutes.Keywords: carrageenan, dry weigth, extract, growth, submersion

A review on the success factors of crowdfunding-based to finance small-scale infrastructure projects

Public-Private Partnership (PPP) schemes in delivering economic and social infrastructure are growing in developing countries worldwide. Various developing countries, including Indonesia, has also been preparing and developing numerous projects, ranging from larger-scale economic infrastructures that include toll roads to multifunction satellites and smaller-scale social infrastructures that include water supply, solid-waste management, and regional hospital projects. With the increasing numbers of smaller infrastructure projects proposed by the local government, attracting financers to invest in these projects is still a challenge the government faces. Financial institutions are still averse to making the appraisal and due diligence to such projects, owing to the nature of little historical evidence of private finance involvement in small-scale infrastructure finance. In some western countries, citizens have taken the initiative to forward and finance their local infrastructure development due to realizing the social, economic, and environmental benefits of civic projects for the local community. Theoretical research has shown the opportunity of utilizing crowdfunding for local urban infrastructure; however, the factors contributing to benefit from this finance method are yet to be identified. This paper seeks to answer questions on what success factors contribute to the opportunity to adapt the crowdfunding scheme to finance a smaller-scale urban infrastructure project by conducting qualitative literature review

What is Behind Green Industry Motive to Maintain Rural Areas?

The environmental damage is one of the essential factors that determine of disasters. Industrial activities that are mostly in urban areas are contributors to this problem. These activities often exploit resources from rural to an urban area. So that industry is required to be actively involved in maintaining the rural area alike implementing a green industry thatcan be represent through the application of green accounting which is disclose environmental information. The purpose of this paper is to explain the involved an industry in rural areas. Especially, to explain benefit and industry motive. This study uses legitimacy theory and stakeholder theory as a theoretical framework to explain the role of industry. The research method used a quantitative approach and seconder data from Indonesia stock exchange with the LQ45 index as a sample. The data analyzed using multiple regression and path analysis to examine environmental factors that influence the economic performance. The result of this study shows that environmental performance and environmental cost has an influence on environmental disclosure then influence economic performance. Furthermore, it can be identified that the company get the benefit from environmental performance and environmental cost. Also, Economic performance is a reason why an industry involved in maintaining the rural area

Sumber-Sumber Pertumbuhan Ekonomi Jawa Timur Periode 2000-2010: Analisis Dekomposisi Struktural

The purpose of this study was to determine the sources of economic growth in East Java using structural decomposition analysis. The study period is divided into two periods, namely the initial period (2000-2006) and the final period (2006-2010). The results show in the early period indicate that changes in final demand are the main determinants of economic growth in almost all sectors of the East Java economy, while changes in production structure (technology effects) tend to have negative effects on growth in almost all sectors other than services. In the final period, improvements to the production structure in almost every sector were able to make a positive contribution to output. Among the final demand categories, the largest output growth came from exports (between provinces) inthe initial period, while in the final period the main source of growth shifted to household consumption. These findings indicate that East Java has the potential for large economic growth through inter-province exports with the support of improved production structures, particularly in the manufacturing sector.Tujuan penelitian ini adalah untuk mengetahui sumber pertumbuhan ekonomi di Provinsi Jawa Timur dengan menggunakan analisis dekomposisi struktural. Pembagian rentang waktu penelitian dibagi menjadi dua periode, yaitu periode awal (2000-2006) dan periode akhir (2006-2010). Hasil penelitian pada periode awal menunjukkan bahwa perubahan permintaan akhir merupakan determinan utama yang mendorong pertumbuhan ekonomi di hampir semua sektor ekonomi Jawa Timur, sedangkan perubahan struktur produksi (efek teknologi) cenderung memberikan pengaruh negatif pada pertumbuhan di hampir seluruh sektor selain kelompok jasa. Pada periode akhir, perbaikan struktur produksi di hampir setiap sektor mampu memberi kontribusi positif terhadap output. Diantara kategori permintaan akhir, pertumbuhan output terbesar berasal dari ekspor (antar provinsi) pada periode awal, sementara pada periode akhir sumber pertumbuhan utama bergeser ke konsumsi rumah tangga. Temuan ini menunjukkan bahwa Jawa Timur memiliki potensi pertumbuhan ekonomi besar melalui ekspor antar provinsi dengan dukungan perbaikan struktur produksi, khususnya pada sektor industri pengolahan
