Constructing Eh-pH Diagrams of Plutonium by Using Its Thermodynamics Properties

ABSTRACT Eh-pH diagrams of Plutonium under standard temperature and pressure (STP) condition are constructed. The stability domain of water is described based on redox reaction of water with oxygen and hydrogen. Two pair lines which are almost paralel to each other are found. Redox reaction of Plutonium poduces four Nerst equations; each equation is represented by one line and one vertical line as a result of non redox reaction. The length of each line depends on other lines. There are two pair lines which are overlapped each other if the concentration of each species equals to 10-9 M. It is also described Eh-pH diagrams for Plutonium with different concentrations. ABSTRAK Telah dibuat diagram Eh-pH Plutonium di dalam udara dengan tekanan dan suhu standar. Daerah stabilitas air ditentukan berdasarkan reaksi redoks air - oksigen dan air - hidrogen. Didapatkan dua pasang garis lurus yang hampir sejajar satu sama lain. Reaksi redoks dari Plutonium menghasilkan 4 persamaan Nerst, tiap persamaan digambarkan dalam bentuk garis dan satu garis tegak akibat reaksi non redoks. Panjang setiap garis sangat bergantung pada garis - garis lainnya. Didapatkan dua pasangan garis yang saling tumpang - tindih kalau konsentrasi masing-masing spesiesnya sama dengan 10-9 M. Digambarkan juga Ehl-pH diagram untuk konsentrasi spesies Plutonium yang tidak sama

This study also shows that there is a partial effect between profitability and debt policy. The result showed the value of -t count < -t table or 0,003 (< 0,05) with the significance of the numbers 0,000 so that profitability has negative and significant effect on debt policy. Simultaneously, there is influence between firm size and auditor opinion on audit delay. The result showed the value of F count greater than F table or 19,466 > 3,160 with significant value 0,000 so that the firm size and auditor opinion have a significant effect on the audit delay. There is a positive and strong relationship with a coefficient of 0.33 and the effect of firm size and auditor opinion on audit delay in the manufacturing companies listed in the Indonesia Stock Exchange amounted to 33%

Factors Affecting Circular Economy Promotion in Indonesia: The Revival of Agribusiness Partnership

IndonesianKonsep ekonomi sirkuler sebenarnya telah dilakukan sejak lama di Indonesia, khususnya pada industri besar dan menengah, namun belakangan ini perencanaan pembangunan ekonomi kurang memperhatikannya.  Perusahaan-perusahaan pabrik kertas dan perkebunan besar termasuk diantara usaha ekonomi yang melaksanakan konsep ini.  Pada skala ekonomi yang lebih kecil dalam bidang pertanian, kerjasama antara perusahaan besar dengan pertanian rakyat sudah berlangsung dengan baik, memberikan keuntungan ekonomi, memperbaiki kualitas lingkungan dan menjanjikan persaingan yang kompetitif. Masyarakat sebenarnya sudah menerapkan konsep ekonomi sirkuler pada sistem usahatani terintegrasi yang mereka lakukan,  namun  perkembangannya masih kurang memuaskan. Faktor-faktor yang terkait dengan kelembagaan sangat berperan dalam mempromosikan konsep ekonomi sirkuler ini di pedesaan dan menjadi penentu keberhasilan program kemitraan hingga mencapai level tertentu.  Melalui kerjasama model kemitraan sebagai perwujudan konsep ekonomi sirkuler, ketiga pilar ekonomi, yakni lembaga pemerintah, sektor swasta, dan masyarakat harus saling mendukung dan berpartisipasi menurut kapasitasnya masing-masing memberikan sumbangan pada pembangunan ekonomi regional. Pemerintah sebagai fasilitator dan regulator, perusahaan swasta sebagai penghela usaha, dan masyarakat sebagai pemasok bahan baku atau pelaku usaha kecil harus saling berinteraksi, bekerjasama dan berpartisipasi dalam program pembangunan ekonomi.  Makalah ini menjelaskan faktor-faktor yang mempengaruhi konsep ekonomi sirkuler untuk mempercepat bangkitnya ekonomi rakyat melalui kemitraan agribisnis.    EnglishCircular economy concept has been less considered in the global framework of economic development in Indonesia during the past decade, although the concept has been continually applied in many medium and large industries.  Pulp and paper enterprises and estate crops agro-industries are among the companies included in this economic trend.  To a smaller economic development, the implementation of circular economy movement in especially agricultural fields has been benefiting rural people, enhancing quality of environment, and promising competitive advantage. Small-scale integrated farming systems have been widely adopted this concept but lack of improvement. Institutional factors have played significant role in promoting circular economy in rural areas.  Institutional role, in this context, is very instrumental to gear regional development towards certain level of improvement.  Through circular economy partnership, the three pillars of development: government, private sector, and rural people are each in the right position to lead in every steps of regional economic development program. These institutions are expected to function as regulator agency to facilitate related activities, as enterprise organization to give hand to initiate and develop certain production, and as supporting society to participate in any programs/activities to achieve certain goals.  This paper addresses influencing factors to promote circular economy to accelerate the revival of people’s regional economy through agribusiness partnership

Pengembangan Agro-Industri Perdesaan dengan Pendekatan One Village One Product (OVOP)

EnglishAgro-industry development in rural areas could be implemented using an OVOP approach. As a people movement, this agro-industry needs active participation of all related institutions. The inter-related elements under the agribusiness system on this approach requests willingness of all related parties, from the upstream to the downstream of agricultural system cycle. The working steps for its application cover the selection of local specific product, identification of product strengths and associated constraints for development for higher quality and for global market, application of product development (processing and marketing) for added value and income improvement, and implementation of evaluation for better future product and business performances. The OVOP approach could be applied in rural areas of Indonesia if all stakeholders along with their respective institutions are in favor of the rural people\u27s interest. IndonesianSalah satu alternatif pengembangan agro-industri di perdesaan dapat dilakukan dengan pendekatan OVOP. Sebagai suatu gerakan masyarakat, pendekatan agro-industri ini membutuhkan partisipasi semua lembaga terkait. Hubungan yang saling mengkait antar elemen dalam sistem agribisnis pada pendekatan ini mengharapkan kesediaan semua pihak, dari hulu ke hilir dalam siklus sistem pertanian. Langkah-langkah operasional untuk pelaksanaannya mencakup pemilihan produk unggulan spesifik lokal, mengidentifikasi potensi dan kendala yang dihadapi jika akan mengembangkan produk tersebut hingga mampu meningkatkan kualitas dan menembus pasar global, melaksanakan kegiatan pengembangan (pengolahan dan pemasaran) untuk memperoleh nilai tambah dan meningkatkan pendapatan, dan melaksanakan evaluasi untuk meningkatkan kekuatan produk dan kinerja USAha. Pendekatan OVOP ini dapat dilaksanakan di Indonesia jika semua pemangku kepentingan bersama instansi masing-masing berpihak pada kepentingan masyarakat perdesaan
