MANAJEMEN TANAH

Memiliki drainase yang baik dan cepat menyerap hujan lebat tanpa aliran permukaan yang besar; setelah panen, tanah tidak mengeras; mampu menyimpan air selama musim kering; mempunyai bongkahan-bongkahan tanpa lapisan cadas; tahan terhadap erosi dan pencucian hara; mendukung adanya populasi organisme tanah dalam jumlah besar; tidak membutuhkan penambahan pupuk untuk berproduksi tinggi; memiliki bau tanah yang khas; menghasilkan tanaman yang sehat dan berkualitas tinggi; adalah ciri-ciri tanah yang baik dan bisa dioptimalkan oleh manusia. Namun pada praktiknya, pengoptimalan selama ini tidak bisa mengatasi beberapa masalah tanah baik pada tanaman dan populasi manusia. Buku ini menjelaskan perlunya usaha konservasi tanah dan manajemen tanah untuk meningkatkan daya dukung tanah menuju perbaikan kualitas tanah.

Round-robin pretest analyses of a 1:6-scale reinforced concrete containment model subject to static internal pressurization

Round-Robin Scheduling

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Round-robin (RR) is one of the simplest scheduling algorithms for processes in an operating system, which assigns time slices to each process in equal portions and in circular order, handling all processes without priority. Round-robin scheduling is both simple and easy to implement, and starvation-free. Round-robin scheduling can also be applied to other scheduling problems, such as data packet scheduling in computer networks. The name of the algorithm comes from the round-robin principle known from other fields, where each person takes an equal share of something in turn.

Non-Linguistic Analysis of Call Center Conversations

The book focuses on the part of the audio conversation not related to language such as speaking rate (in terms of number of syllables per unit time) and emotion centric features. This text examines using non-linguistics features to infer information from phone calls to call centers. The author analyzes "how" the conversation happens and not "what" the conversation is about by audio signal processing and analysis.

Solid-state Lasers

A solid-state laser uses and gains medium that is a solid, rather than a liquid such as dye lasers or a gas such as gas lasers. Semiconductor-based lasers are also in the solid state, but are generally considered separately from solid-state lasers. This book gathers research in the field.

Solid-State Shear Pulverization

From the Preface This book is the first extended look at a new and multifaceted polymer processing technology that has already been discussed in numerous articles. Called Solid-State Shear Pulverization (S3P), this innovative process produces polymeric powders with unique physical properties not found in the output of conventional size-reduction methods.... This technology, which utilizes a pulverizer based on a modified co-rotating twin-screw extruder..., has profound implications for both the creation of new polymer blends and recycling of plastic and rubber waste. Unlike [earlier processes] where polymers are melted prior to pulverization, ...pulverizing mixtures of polymers with the S3P process...does not involve melting. By contrast, S3P maintains polymers in the solid state and avoids the additional heat history that occurs during [other processes], which can be detrimental to the physical properties of pulverized materials. The research and development of the S3P technology...has grown significantly since 1990 from the development of a new plastics recycling process to a much broader polymer processing method that allows intimate mixing of polymers with very different viscosities, sold-state dispersion of additives, including pigments, and continuous production of powder with unique shapes and larger surface areas. Polymeric powders are of growing importance to plastics processors due to the increase use of plastics in various applications, such as rotational molding, powder coatings, and compounding, which require powder as the feedstock. ...[I]t has become clear that this process allows for in-situ compatibilization of dissimilar polymers by applying mechanical energy to cause chemical reactions. This aspect of S3P technology that we describe in this book should [be useful in] developing new polymer blends with the use of pre-made compatibilizing agents. In addition, it has been discovered that S3P efficiently mixes polymer blends with different component viscosities, resulting in the elimination of phase inversion. The S3P process directly produces blends with matrix and dispersed phase morphology like those obtained after phase inversion during a long melt-mixing process. This phenomenon is of practical importance because a long processing time is required by conventional melt-mixing to produce a stable blend morphology. S3P is also advantageous for producing thermoplastic or thermoset powder-coating compounds in a one-step process as opposed to a conventional multi-step operation that involves melt extrusion followed by batch grinding. The major capabilities of this new process can be summarized as follows: o Continuous powder production from plastics or rubber feedstocks o Blending of immiscible polymers o Efficient mixing of polymers with unmatched viscosities o Environmentally friendly recycling of multicolored, commingled plastics waste o Sold-state dispersion of heat-sensitive additives o Engineered plastic/rubber blends Materials and processes well illustrated The text is well illustrated with 60 photographs, micrographs, diagrams and others figures.

Prospek Pengembangan Potensi Sumberdaya Kelautan Madura Kepulauan

Madura sebagai bagian wilayah Jawa Timur terbagi menjadi empat wilayah Kabupaten yaitu, Sampang, Pamekasan, Sumenep dan Bangkalan. Disamping budaya yang bernilai khas, masyarakat Madura memiliki ciri lainnya seperti falsafah yang dipegang teguh yang berbunyi “Bupak (ayah), Babuk (ibu), Guru (Ulama/kiyai), Rato (pemerintah) atau Babuk–Bupak–Guru–Rato (Madani, 1999). Falsafah bersumberkan kepada ajaran Islam yang dianutnya secara fanatik, yang tersirat dari kenyataan bahwa hampir 60% pondok pesantren yang ada di Indonesia umumnya berada di Madura (Raharjo, 1988). Sementara itu, dalam kehidupan sehari-hari, umumnya masyarakat Madura lebih mentaati perintah kedua orang tua dan fatwa Ulama tanpa memperdulikan rasionalitas dari perintah tersebut dibandingkan pihak lainnya. Suasana demikian merupakan perwujudan penghayatan keagamaan yang terasa begitu kental, bahkan tidak jarang terjadi penolakan pada hal-hal yang bersifat baru, apabila tidak ada legitimasi dari Ulama. Hal tersebut perlu diantisipasi, karena terkait dengan langkah kemungkinan masuknya budaya luar yang kurang sesuai dengan tatanan budaya masyarakat Madura yang religius.

Pemasaran Hasil Perikanan

Sektor perikanan Indonesia pada awalnya merupakan subsektor pertanian “agrokompleks”. Dalam perkembangannya, perikanan telah menjadi sektor tersendiri mengingat peranannya yang penting dan strategis, potensinya yang besar dan memberikan kontribusi yang nyata terhadap pembangunan nasional Indonesia sebagai negara maritim. Pemasaran ikan merupakan kegiatan yang sangat penting pada sektor perikanan sebagai rangkaian mata rantai agribisnis perikanan yang terdiri dari rantai pra produksi, rantai produksi (penangkapan ikan dan budidaya ikan), rantai pasca produksi (pengolahan dan pemasaran). Kegiatan pemasaran dapat menciptakan berbagai kegunaan (utility), yaitu kegunaan tempat (place utility) melalui distribution, kegunaan waktu (time utility) dan bentuk (form utility) melalui kegiatan processing, kegunaan milik (possession utility) melalui kegiatan selling and buying, dan lain-lain. Semua kegiatan pemasaran (fungsi pemasaran) dapat meningkatkan nilai tambah (added value) suatu komoditi yang mengarah pada peningkatan share (bagian yang diterimakan kepada para pelaku pemasaran) dapat berupa keuntungan bagi para produsen (pembudidaya ikan, nelayan, petambak garam), pedagang perantara hingga konsumen (institutional market: usaha pengolahan baik skala UMKM maupun industri, horeka: hotel-restaurant-kafe, dan konsumen akhir).
