Authors: Layly Ika Rahmatul , Wiguna Nita Oktavia 
Published: December 2017

In detergent industry, enzymes are used enormously in terms of quantity and economic value. Lipase catalyzes the hydrolysis of triglycerides into diglycerides and monoglycerides by releasing fatty acids. Lipase is produced by bacteria, fungi, and yeasts. This study aims to determine the potential of Alcaligenes faecalis lipase for its application as biodetergen, through stability testing of its lipase activity against detergent components by exposing the enzyme to the commercial detergents, as well as performance testing through washing. Alcaligenes faecalis lipase was produced using Luria Bertani (LB) culture medium supplemented with 1% olive oil inducer. Production is carried out for 24 hours, and the enzyme was harvested at the 18th hour. The harvested enzyme was tested for their stability after being exposed to commercial detergents at a concentration of 1-5%. Results showed that the exposure to the detergents decreased the enzyme activity to 22, 38, 48, 68 and 90%. Performance test showed that the olive oil impurity removal from the fabric was 29%.Keywords: Alcaligenes faecalis Lipase, biodetergent, lipase activities, washing test AbstrakPada industri detergen penggunaan enzim sangatlah besar baik secara jumlah maupun nilai ekonomi.

EFFECT OF AUXIN AND CYTOKININ ON MICROPROPAGATION OF BINAHONG (Anredera cordifolia (Tenore) Steenis)Binahong (Anredera cordifolia (Tenore) Steenis) is known as miraculous medicinal plant for its potential to cure for various kinds of diseases such as diabetes, stabilizing blood pressure and circulation, accelerating wound healing, and preventing stroke. In order to provide high quality seedlings of this medicinal plant continuously in large amount, the study on binahong micropropagation was performed. Plant growth regulators of auxins and cytokinins were applied in single or in combination so as to observe their effect on the growth of binahong explants. The results showed that 2,4-D induced callus formation in large diameter on all treatments. Nevertheless, this plant growth regulator had a negative effect on growth and development of shoot and leaves. In the combination treatments between IAA and BAP, it revealed that the higher the concentration of BAP in the media, the lower the number of leaves initiated on shoot explants. Increasing the concentration of IAA upto 1.5 ppm influenced the increasing of shoot tallness and the number of internodes. Our results can be useful for improving the binahong shoot propagation efficiency, as well as callus culture studies.Keywords: Auxin, cytokinin, callus, micropropagation, medicinal plantABSTRAKBinahong (Anredera cordifolia (Tenore) Steenis) dikenal sebagai tanaman obat ajaib karena dapat digunakan untuk pengobatan berbagai macam penyakit seperti diabetes, melancarkan peredaran dan tekanan darah, mempercepat penyembuhan luka, mencegah stroke. Dalam mendukung ketersediaan bibit tanaman obat herbal yang berkualitas secara berkelanjutan maka dilakukan kajian tentang perbanyakan bibit tanaman binahong. Zat pengatur tumbuh auksin dan sitokinin dalam bentuk tunggal maupun kombinasi diaplikasikan pada penelitian ini untuk melihat pengaruhnya terhadap berbagai eksplan binahong. Hasilnya menunjukkan bahwa 2,4-D merangsang pembentukan kalus dengan ukuran yang besar pada semua perlakuan. Namun demikian zat pengatur tumbuh ini memberikan pengaruh negatif terhadap pertumbuhan dan perkembangan tunas dan daun. Dari perlakuan kombinasi zat pengatur tumbuh IAA dan BAP, pertambahan konsentrasi BAP di dalam media menurunkan jumlah daun yang terbentuk pada eksplan pucuk binahong. Demikian pula dengan pertambahan konsentrasi IAA hingga 1,5 ppm sangat berpengaruh terhadap pertumbuhan meninggi tunas dan pertambahan jumlah ruas. Hasil dari studi ini dapat dimanfaatkan untuk studi lanjutan dalam meningkatkan efisiensi perbanyakan tunas serta kultur kalus binahong.Kata kunci: Auksin, sitokinin, kalus, perbanyakan mikro, tanaman obat herbal

Pratritmen Kimia terhadap Tandan Kosong Sawit Menggunakan NH4OH Konsentrasi Rendah untuk Meningkatkan Produksi Biogas
Authors: Parlina Iin 
Published: December 2017

Indonesia sebagai negara penghasil minyak kelapa sawit terbesar di dunia memiliki potensi hasil samping limbah padat tandan kosong sawit (TKS) sekitar 22 juta ton/tahun. Selama ini belum ada pemanfaatan TKS yang maksimal untuk meningkatkan nilai tambah dari TKS kecuali konversi menjadi listrik melalui teknologi pembakaran. Biasanya, sebagian besar limbah TKS dikembalikan ke lahan perkebunan sebagai penutup tanah (mulsa) yang selanjutnya akan didegradasi secara alami oleh lingkungan.Namun, prosess ini justru memiliki potensi emisi CH4 ke atmosfer yang menyebabkan efek rumah kaca. Teknologi biokonversi TKS untuk menjadi bahan kimia dan energi dapat menjadi pilihan teknologi yang menjanjikan dalam pencegahan perubahan iklim. Manfaat teknologi ini tidak hanya dapat mencegah terjadinya emisi alami CH4 ke atmosfer tetapi juga dapat memanfaatkan gas CH4 menjadi energi untuk substitusi konsumsi listrik dan bahan bakar fosil. Namun, sifat rekalsitransi biomassa TKS menjadi faktor pembatas paling utama dalam konversi TKS menjadi gas CH4. Oleh karena itu, teknologi pratritmen diperlukan untuk mengurangi karakteristik rekalsitransi TKS sehingga efisiensi konversi menjadi CH4 dapat lebih optimal. Teknologi pratritmen untuk memecah sifat rekalsitransi dalam TKS masih tergolong mahal namun harus bisa dilakukan agar konversi TKS ke gas CH4 menjadi lebih tinggi. Dalam riset ini, pratritmen TKS digunakan bahan kimia NH4OH konsentrasi rendah. Teknologi pratritmen dengan NH4OH konsentrasi rendah ini dinilai lebih murah biayanya. Selain itu, proses pratritmen ini dapat meningkatkan produksi CH4 cukup signifikan yaitu sekitar 33,8% lebih tinggi bila dibandingkan tanpa pratritmen.

Published: December 2017

Salah satu hasil proses biodegradasi sampah di TPA adalah lindi yang merupakan polutan organik yang berbahaya bagi lingkungan karena berpotensi mencemari tanah dan air tanah. Penelitian ini bertujuan untuk mengetahui kuantitas dan kualitas lindi dari sampah di TPA Kaliwlingi Brebes melalui uji lisimeter. Kuantitas lindi penting untuk memperkirakan spesifikasi disain unit pengolahan termasuk metode pengolahannya. Sedangkan karakteristik lindi penting untuk menentukan efisiensi pengolahan atau target kadar polutan yang diinginkan agar sesuai standard baku mutu. Dari pengamatan diperoleh kuantitas lindi per massa sampah rata-rata mencapai 1.060 liter/kg, sedangkan nilai pH lindi rata-rata 7,6 atau cenderung alkaline. Dari data pengamatan, semakin tinggi kadar air akan semakin besar kuantitas lindi yang dihasilkan. Karakterisasi lindi terhadap parameter BOD5, COD, NH3-N dan TKN menghasilkan nilai yang bervariasi. Nilai rata-rata serta rentang minimal-maksimal yang didapat; BOD5 90,7 mg/l (65 mg/l-130 mg/l), COD 9.679,7 mg/l (6.300 mg/l-12.200 mg/l), NH3-N 134,4 mg/l (80 mg/l-190 mg/l) dan TKN 672,5 mg/l (540 mg/l-890 mg/l). Rasio BOD5/COD sebesar 0,01 menunjukkan tingkat low biodegradability dalam materi organiknya, hal ini disebabkan waktu pengamatan yang relatif singkat dan proses degradasi biologis masih berlangsung.Nilai rasio BOD5/COD yang diperoleh belum menunjukkan nilai yang representatif untuk sampah di TPA Kaliwlingi. Hasil dari karakterisasi lindi untuk beberapa parameter menunjukkan bahwa biomassa atau sampah yang diteliti tergolong usia muda dan masih dalam proses dekomposisi.Kata kunci : karakterisasi, produksi, organik, lindi, TPA sampah

Published: December 2017

O presente artigo apresenta os resultados de uma pesquisa[1] baseada na interação entre o design e o artesanato brasileiro a partir do século XXI. Na busca pelo reconhecimento dessa interação e diferentes formas de atuação que podem ocorrer, foram analisados seis modelos de relacionamento entre designers e artesãos, sendo dois modelos quando os designers atuam em núcleos de extensão universitária/acadêmica, dois em associações sem fins lucrativos e dois como profissionais autônomos, que junto a grupos produtivos desenvolvem, por meio de diferentes métodos, ações com significativos impactos sociais, ambientais e econômicos. A partir das similaridades e divergências entre esses formatos é possível observar e realizar análises que permitem orientar pesquisas, projetos e novas políticas públicas buscando o constante aprimoramento desta atuação.ABSTRACTThe present article shows the results of a researchbased on the interaction between design and Brazilian handcrafts from the 21th century. In order to have a recognition of this interaction and the different forms it can occur, six models of relationship among designers and handcrafters were analysed: two of them were performed by university extension centers, two by non-profit organizations and the other two by autonomous professionals. When these models interact with productive groups, they develop in many different methods actions what result in social, environmental and economical impacts. From the similarities and differences between these formats, the improvement of the interaction between design and handcraft is notorious. This perception allows the approach of new researches, projects and new public politics.
OPTIMIZATION OF GREEN-BUILDING DESIGN PROCESSES - CASE STUDY
Authors: Orsi Alessandro , Guillamón Ignacio Guillén 
Published: December 2017

The development of a green-building project following a specific reference standard such as LEED, brings new conditions and restrains for all subjects involved in the process. Such changes affect technicians, owners, bureaucracy and also the management tasks either during design or construction phases. Within this scope, project management plays a key role for the optimization of the design-project development. This research analyzes the design process of a single case-study project from the project management perspective, taking into consideration all the activities that negatively affected the project design development. The project selected for the scope of the research is a new school complex located in Northern Italy currently pursuing the LEED Gold certification with a project cost of 13,2 million Euros. A new methodology was created in order to analyze the project and evaluate the effects of detected project-management issues under three different points of view: costs, time and building sustainability. Such “issues” were identified by researchers on the basis of the LEAN-definition of “waste”. The scope of the research is to develop and test a methodology for the optimization of the project management processes during the development of a LEED building design in Europe through the detection and evaluation of process wastes. The results showed that project management issues related to green-building tasks affect considerably the cost, schedule and sustainability of the project design and vice versa, the accuracy of the project management tasks affect the sustainability features of the final building design.

Os sistemas de tratamento de efluentes são utilizados há anos para reduzir os riscos de contaminação e os impactos no ambiente. Porém, até pouco tempo atrás não se considerava os efeitos causados pelo próprio sistema. Portanto, os profissionais da área passaram a incorporar novos critérios e abordagens na escolha das técnicas disponíveis. Uma das formas de avaliar os impactos de maneira global, é através da Análise de Ciclo de Vida (ACV). Os resultados da análise apontaram dois processos como gargalos do sistema, o consumo de energia na fase de operação e o gerenciamento do lodo.
COMPACIDADE DOS ESPAÇOS ARQUITETÔNICOS

Published: December 2017

A maioria da população do mundo vive em cidades, segundo as Nações Unidas (2015), fazendo o estudo da densidade urbana de grande importância. Por outro lado, o número de edifícios altos aumentou acentuadamente nos grandes centros urbanos, como o de São Paulo que atualmente tem cerca de 12 milhões de habitantes, apresentando um processo de construção verticalizada e , ao mesmo tempo, uma redução significativa nas áreas construídas per capita. Grande parte da população opta por unidade de habitação compacta, buscando uma boa localização com infraestrutura e serviços que incrementam a qualidade de vida. Apartamentos com menor áreas privadas em locais mais qualificados são resultados da formação de famílias com menos filhos ou de família com idosos, que buscam modelos mais adequados para a vida em grandes centros metropolitanos. Este processo de verticalização tem produzido um aumento na compacidade das unidades habitacionais, o que pode reduzir a funcionalidade arquitetônica e a satisfação do usuário. Neste âmbito, o Índice de Compacidade é um dos indicadores mais úteis para avaliar o quanto o projeto de um espaço pode estar longe do perímetro mais econômico, aquele determinado por suas paredes externas. É comum se adotar as áreas construídas como determinantes do custo da construção, esquecendo-se que o custo é uma função também das quantidades de paredes, materiais e revestimentos empregados. Neste contexto, o trabalho busca mostrar que a compacidade deve ser analisada de forma tridimensional, pois determina o desempenho do espaço interno, como o sistema de ar condicionado, a eficiência energética e o custo das divisórias internas e dos materiais utilizados. Por fim, busca-se estabelecer um método para determinação do índice de compacidade espacial. Os resultados mostram que espaços pequenos e compactos tendem a induzir funções sobrepostas, o que pode agravar os conflitos de uso. Tais espaços requerem um design detalhado que permita usos simultâneos e diferentes para ser adaptado às novas necessidades e aos perfis dos usuários contemporâneos.
Double Affirmation: Medievalism as Christian Apologetic in the Arthurian Poetry of Charles Williams
Authors: Higgins Sørina 
Published: December 2017

In his unfinished cycle of Arthurian poems, Charles Williams developed a totalizing mythology in which he fictionalized the Medieval. First, he employed chronological conflation, juxtaposing events and cultural references from a millennium of European history and aligning each with his doctrinal system. Second, following the Biblical metaphor of the body of Christ, Blake’s symbolism, and Rosicrucian sacramentalism, he embodied theology in the Medieval landscape via a superimposed female figure. Finally, Williams worked to show the validity of two Scholastic approaches to spirituality: the kataphatic and apophatic paths. His attempts to balance via negativa and via positiva led Williams to practical misapplication—but also to creation of a landmark work of twentieth century poetry. . . . the two great vocations, the Rejection of all images before the unimaged, the Affirmation of all images before the all-imaged, the Rejection affirming, the Affirmation rejecting. . . —from ‘The Departure of Dindrane’ —O Blessed, pardon affirmation!— —O Blessed, pardon negation!— —from ‘The Prayers of the Pope’
