Published: September 2018

Leucaena (Leucaena leucocephala cv. Tarramba) is a source of protein from the legume family. Tarramba varieties able to adapt well in tropical area such as West Nusa Tenggara and East Nusa Tenggara. This study aimed to identify the growth response and embryogenic callus morphology of lamtoro (L. leucaena cv. Tarramba) in embryos different ages and auxin 2,4-D levels. This research was used explants derived from lamtoro (L. leucocephala cv. Tarramba) as much 400 explants. this study conducted of 16 treatments with two factors, the first factor is the provision of PGR 2,4-D concentration of 0.5 mg L-1, 1 mg L-1, 1.5 mg L-1 and 2 mg L-1. The second factor was the type of embryo such as mature embryo, cotyledon, heart, and pre-globular. Each treatment was repeated 25 replications. This study uses a randomized complete design (CRD) with two factor. Data were analyzed using analysis of variance and if there was significant difference, data were further analyzed using Duncan’s multiple range test. Analysis of variance showed that PGR 2,4-D at a concentration of 1.5 mg L-1 and the type of optimum embryo was mature embryo callus on parameters as height, diameter increment callus, and callus color scores were significantly different (P <0.05). callus texture parameter indicates results that are uniform throughout the treatment that was compact callus. Lamtoro plant embryogenic callus (L. leucocephala cv. Tarramba) indicate an optimal response at the concentration of PGR 2,4-D 1.5 mg L-1 and the type of embryo was mature embryo.

BNCC e o passado prático: Temporalidades e produção de identidades no ensino de história
Authors: Pereira Nilton Mullet , Rodrigues Mara Cristina de Matos
Published: September 2018

O ano de 2016, no Brasil, foi marcado por uma intensa discussão em torno da Base Nacional Comum Curricular (BNCC) para o ensino de história. Os debates giraram em torno, sobretudo, das narrativas que deveriam ou não se fazer presentes no documento, uma vez que a primeira versão da BNCC procurou romper com décadas de um ensino eurocêntrico de história e promover o destaque para as histórias do Brasil, da África, dos afrodescendentes, dos latino-americanos e dos povos indígenas. Esta investigação debruçou-se sobre as três versões da BNCC disponibilizadas pelo Ministério da Educação e sobre as guerras de narrativas no interior do campo da história e do ensino de história. Em uma abordagem que se situa entre teorias da história e do ensino de história, este artigo apresenta problematizações a essa base, tendo como eixo a questão das identidades e das temporalidades. A partir de um diálogo teórico com pensadores como Hayden White e da noção de passado prático, entre outros que permitem pensar os processos de narrativização do passado, bem como num diálogo com o campo do ensino de história, demonstramos como as duas versões que se seguiram à primeira representam um retorno a uma velha história contínua, europeia e desconectada das demandas sociais e identitárias do tempo presente.

Authors: Georgiou Andreas Marios , Kontos Themis
Published: September 2018

A GIS toolset was developed to support spatial analysis functions, visualization and extraction of a variety of input variables for air quality assessment. The developed toolset allows the automated processing of large amounts of ASCII data converting to points and raster data and the examination of the correlation among them. A case study was performed in Athens basin in Greece. Using the developed GIS toolset, topographic, climatic characteristics and air pollution conditions as well correlations were derived by processing the input data. In addition, thematic maps illustrating the spatial distribution of each parameter were extracted.  The developed GIS toolset greatly reduced the time and effort needed to process the GIS data, and provided a useful tool for a wide variety of environmental applications. The tool uses ArcObjects as the programming language to incorporate equations for statistical analysis in a monthly and a yearly time step. This versatile programming language allows advanced users to incorporate more complex formulations for more accurate results as detailed data is acquired to develop routines for calibration when reference data exist. Results verified the usefulness and feasibility of the developed platform.
Batak dan Bukan Batak: Paradigma Sosiohistoris tentang Konstruksi Identitas Etnik di Kota Medan, 1906-1939
Authors: Hidayat Hidayat , Damanik Erond L.
Published: September 2018

This research discusses the sociohistorical paradigm of Batak label construction on Mandailing and Angkola ethnicities in the city of Medan, 1906-1939. Throughout the year, the two ethnic migrants from southern Tapanuli clashed in Medan because of the Batak labeling. The Mandailing ethnic group rejected the Batak label, while the Angkola ethnic group affirmed on that label. The disputes have an impact on the division of political, economic, religious and cultural identities. The rejection from Mandailing ethnic on Batak labeling continues to occur until 2017. This research aims to describe the construction of the Batak label by answering general questions on how do the two ethnic groups fight because of the Batak label? Specifically, this article also answers the origin of Batak labeling? Why is the label debated? To explain this case, the theory of social construction is used with the sociohistorical paradigm and the case study research method. The results of the study that the Batak label is considered as a foreign ethnographic construction with a pejorative tone and disputes occur because of the strategic stability of identity as a social radar to understand the social world.
The new speakers of Lombard
Authors: Coluzzi Paolo
Published: September 2018

Lombard is one of the 12–15 non-recognized regional languages spoken in Italy. This article focuses on the new speakers of Lombard, i. e. people who have learned or are learning Lombard as a second language. Through an open questionnaire the author has probed into various aspects concerning these new speakers’ competence and learning trajectories, situations and opportunities for using the language, motivations, aims, commitment, metalinguistic awareness and the difficulties encountered in acquiring the language. Issues of authenticity, legitimacy and especially of identity and political allegiances have also been looked at. After a brief outline of the Lombard language and the research on new speakers that has been carried out so far, the article presents the methodology employed, followed by an analysis of the answers provided, which show that new speakers are very different from native speakers in sociolinguistic terms. A discussion of the results and some conclusions close the article.
Chinese open information extraction based on DBMCSS in the field of national information resources
Authors: Gan Jianhou , Huang Peng , Zhou Juxiang , Wen Bin
Published: September 2018

Binary entity relationship tuples can be applied in many fields such as knowledge base construction, data mining, pattern extraction, and so on. The purpose of entity relationship mining is discovering and identifying the semantic relationship. As the relationship between entities are different from the general domain, using supervise learning methods to extract entity relationships in the field of ethnicity is difficult. After research, we find that some words can be used in the context of a sentence to describe the semantic relationship. In order to salve the existing difficulties of building tagged corpus and the predefined entities-relationships model, this paper proposes a method of density-based multi-clustering clustering of semantic similarity (DBMCSS) to mine the binary entity relationship tuples from the Chinese national information corpus, which can extract entity relationships without a training corpus.
Preparation and properties of biodegradable polymer/nano-hydroxyapatite bioceramic scaffold for spongy bone regeneration
Authors: Rahman Mohammed Mizanur , Shahruzzaman Md. , Islam Md. Sazedul , Khan M. Nuruzzaman , Haque Papia
Published: September 2018

Biodegradable polymer/bioceramic composite scaffolds can overcome the limitations of conventional ceramic bone substitutes, such as brittleness and difficulty in shaping. To better mimic the mineral components and microstructure of natural bone, a novel nano-hydroxyapatite (nHAp)–chitosan composite scaffold including gelatin and polymer (poly(lactic acid)) with high porosity was developed using a sol-gel method and subsequently lyophilized for efficient bone tissue engineering. The nanocrystalline structure of hydroxyapatite was observed using X-ray diffraction analysis and the composite showed crystallinity due to the presence of nHAp. The pore diameter of the composite containing 5% nHAp was found to be 125 μm, while the composites with 10%, 15%, and 20% nHAp revealed a smaller pore size in the range of 15–28 μm. The highest compressive strength of 5.5 MPa was observed for the 10% nHAp-containing scaffold, whereas thermogravimetric analysis showed 90%–94% degradation at a temperature of 600°C, which demonstrated its excellent thermal stability. Antibacterial and cytotoxicity test results revealed that the composite is resistant toward microbial attack and has low sensitivity in cytotoxicity. The compressive strength data suggests that the composite does not have enough strength as that of human compact bone; however, the highly porous structure as observed in scanning electron microscopy makes it possible for use as an excellent substrate in the spongy bone of humans.

Authors: Aldemir Ramazan , Demirci Esra , Bayram Ayşe Kaçar , Canpolat Mehmet , Ozmen Sevgi , Per Hüseyin , Tokmakci Mahmut
Published: September 2018

Aims

The aim of this study is to evalute the effects of methylphenidate and atomoxetine treatments on electroencephalography (EEG) signals in volunteer children diagnosed with Attention Deficit and Hyperactivity Disorder(ADHD).

Methods

The study contained 40 children all of whom were between the ages of 7 and 17. The participants were classified into two groups as ADHD (n=20), which was in itself divided into two groups as ADHD-MPH (ADHD- Metylphenidate treatment) (n=10) and as ADHD-ATX (ADHD-Atomoxetin treatment) (n=10), and one control group (n=20). Following the first EEG recordings of the ADHD group, long-acting methylphenidate dose was applied to one ADHD group and atomoxetine dose was applied to the other ADHD group. The effect of optimal dosage is about for 4-6 weeks in general. Therefore, the response or lack of response to the treatment was evaluated three months after the beginning of the treatment.

After methylphenidate and atomoxetine drug treatment, in order to obtain mean and maximum power values for delta, theta, alpha and beta band, the EEG data were analyzed.

Results

The EEG power spectrum densities in all the bands yielded similar findings in both methylphenidate and atomoxetine. Although statistically significant frequency values of the electrodes were amplitude and maximally varied, in general, they appeared mostly at both frontal and temporal regions for methylphenidate and atomoxetine.

Conclusion

Especially, after atomoxetine treatment, Quantitative Electroencephalography (QEEG) rates at frontal area electrodes were found statistically more significant than methylphenidate QEEG rates. What has been researched in this study is not only whether QEEG is likely to support the diagnosis, but whether changes on QEEG by treatment may be related to the severity of ADHD as well.

Querying Log Data with Metric Temporal Logic
Authors: Brandt Sebastian , Kalaycı Elem Güzel , Ryzhikov Vladislav , Xiao Guohui , Zakharyaschev Michael
Published: September 2018

We propose a novel framework for ontology-based access to temporal log data using a datalog extension datalogMTL of the Horn fragment of the metric temporal logic MTL. We show that datalogMTL is EXPSPACE-complete even with punctual intervals, in which case full MTL is known to be undecidable. We also prove that nonrecursive datalogMTL is PSPACE-complete for combined complexity and in AC0 for data complexity. We demonstrate by two real-world use cases that nonrecursive datalogMTL programs can express complex temporal concepts from typical user queries and thereby facilitate access to temporal log data. Our experiments with Siemens turbine data and MesoWest weather data show that datalogMTL ontology-mediated queries are efficient and scale on large datasets.

Quality Indicators in Ambulatory Surgery: A Literature Review Comparing Portuguese and International Systems
Authors: Nunes João Silva , Gomes Rebeca , Povo Ana , Castro Alves Eurico
Published: September 2018

Introduction: According to several studies conducted in North America and Europe, ambulatory surgery is a practice that has grown over the years, and both the number of more complex surgical procedures deemed suitable for ambulatory surgery and the number of patients with different co-morbidities which are now suitable for this type of procedure have been increasing. In order to respond to the increased number of day surgeries, as well as to avoid a potential proportional increase in perioperative morbidity, quality control systems must be adopted to enable continuous improvement and minimise predicted risks. The purpose of this study is to review global quality indicators used in ambulatory surgery and compare them with those used in Portugal.Material and Methods: The authors conducted a comprehensive search of medical databases, using MeSH words. Limits were applied to include only studies published after 1998 written in Portuguese, English and Spanish. Ambulatory surgery indicators for Portugal were also obtained.Results: Twenty-one different quality indicators for ambulatory surgery were identified. The Portuguese Healthcare Regulation Authority has defined seven quality indicators for ambulatory surgery.Discussion: The Portuguese quality indicators for ambulatory surgery are generally well adapted to current international practices. Nevertheless, after analysing the relevant international literature based on this study, it is important to consider two additional indicators for ambulatory surgery – same day surgery cancellations and patient satisfaction.Conclusion: On the literature review, same day surgery cancellations and patient satisfaction should be included in the National Health Assessment System created by the Portuguese Healthcare Regulation Authority.

How is Bariatric Surgery Improving the Quality of Life of Obese Patients: A Portuguese Cross-Sectional Study
Authors: Silva José , Vasconcelos Henrique , Figueiredo-Braga Margarida , Carneiro Silvestre
Published: September 2018

Introduction: Obesity is often accompanied by psychological distress and both can reduce patients’ quality of life. Bariatric surgery is proven to be a good method to reduce weight and to alleviate comorbidities, leading ultimately to an improvement in quality of life.Material and Methods: The authors studied 80 patients enrolled in the Multidisciplinary Bariatric Unit of a central hospital in Porto, Portugal. Patients submitted to Roux-en-Y gastric bypass and sleeve procedures were compared. Laboratory parameters were collected from patients’ files. Quality of life and psychological state - depression and anxiety, were evaluated using the Portuguese versions of the Medical Outcomes Study SF-36 and the hospital anxiety and depression scale, respectively, within one to two years of the surgery.Results: A total of 51 patients were operated and completed a quality of life evaluation, while 21 patients were in a pre-operatory group (control). Patients subjected to bariatric surgery had higher scores of SF-36 and lower scores in both hospital anxiety and depression scale (anxiety and depression) subscales (p < 0.001); SF-36 presented a Pearson correlation coefficient of 0,475 (p = 0.004) with hemoglobin A1c. Sleeve had better results in the hospital anxiety and depression scale-depression subscale (p = 0.073).Discussion: In this population, bariatric surgery led to better results, regarding both metabolic and psychological evaluations. No significant differences were found between gastric bypass and sleeve. However, further analyses must be performed.Conclusion: This study supports the theory that bariatric surgery contributes to the improvement of obese patients’ quality of life and psychological state.

Authors: Brandão Maria da Piedade Moreira , Martins Laura , Szewczyczak Marlena , Talarska Dorota , Philp Ian , Cardoso Margarida Fonseca
Published: September 2018

Introduction: According to the OECD, Portugal and Poland rank below average in several well-being measures such as income and wealth, and health status. Investigating how people perceive the threats to health in these two countries, is an important issue to address priority needs. To meet this need, the objective of this paper was to compare the perceptions of the threats to the health and well-being among the Polish and Portuguese older persons and explore differences between the countries in respect of patterns of self-rated health.Material and Methods: A Cross-sectional study with two convenience samples from primary health care services of Poland and Portugal was conducted; 480 adults aged 65 and over (247 Portuguese) were included. The EASYCare standard assessment of 2010 was applied under a joint project of both countries. The association between ‘self-rated unhealthy’ and socio-demographic and threats to health variables was examined using logistic regression.Results: In both countries about two thirds of the older persons self-rated their health as unhealthy. Having more than enough finances was associated with a significant lower odds of being unhealthy compared with those without enough finances at the end of the month (Portugal: OR = 0.25, 95% CI 0.10 to 0.63; Poland: OR = 0.33, 95% CI 0.12 to 0.88). Visual problems, bodily pain, memory loss, feeling bored or lonely and reporting shortness of breath during normal activities was consistently associated with fair or poor self-rated health.Discussion: These findings provide important information regarding the health profile of older people which can help in the development of people-centred health systems where their lives and well-being can be improved. Conclusion: The unhealthy perception of older people was consistently associated with indicators of major health threats.

Gestão municipal de resíduos sólidos urbanos à luz da Política Nacional de Resíduos: estudo de caso no município de Japeri, RJ, Brasil
Authors: Dos Reis Paula Thaise Bermudez , Mattos Ubirajara Aluizio de Oliveira , Da Silva Elmo Rodrigues
Published: September 2018

Este artigo visa analisar a gestão de resíduos urbanos (RSU) no município de Japeri, Região Metropolitana do estado do Rio de Janeiro, Brasil, à luz da Política Nacional de Resíduos Sólidos, criada em 2010, identificando os entraves na sua implantação. Trata-se de pesquisa de abordagem qualitativa realizada entre 2015 e 2016. Os procedimentos de coleta de dados utilizados foram: revisão da literatura; análise documental; entrevistas com gestores; observação direta e uso da técnica de grupo focal com representantes da comunidade. O estudo analisou a gestão de RSU de Japeri com uma perspectiva inovadora e colaborativa, ao usar a técnica do grupo focal, a qual evidenciou a importância em se envolver a comunidade na compreensão dos seus problemas e se mostrou adequada para fomentar esse debate. Entre os desafios a serem enfrentados por Japeri, tem-se: implantar o Plano Municipal de Gestão Integrada de Resíduos Sólidos (PMGIRS); reduzir a dependência dos órgãos estaduais e federais na gestão; universalizar a coleta regular de resíduos; ampliar a cobertura da coleta seletiva; envolver a sociedade na gestão, entre outros. Uma das limitações do estudo foi a pouca qualidade e disponibilidade de dados atuais sobre a gestão municipal de resíduos. A complexidade do tema também não permitiu que todas as questões fossem contempladas no estudo. A maior contribuição da pesquisa foi a sua abordagem, ao dar voz às demandas e sugestões de representantes da comunidade. Para o sucesso do PMGIRS, a participação social é imprescindível, a fim de impedir a sua descontinuidade ou que ele se transforme em mero instrumento político. Espera-se que a técnica de grupo focal empregada possa ser adaptada a outros contextos. Devido à escassez de estudos mais aprofundados sobre o tema, este artigo poderá vir a contribuir com o preenchimento dessa lacuna.

Stroke is a leading cause of death and long-term disability. This due to the ischemic event that cause by embolism of blockage blood flow. Thrombolytic agent plasminogen activator (tPA) is the only treatment approved by FDA. However, the used of tPA is limited to the short time window period. Neural stem cells (NSCs) show the potential to repair neuronal damage naturally after stroke. However, isolating NSCs is a challenging process due to the limitations of the method and its invasiveness. Some studies that had used mesenchymal stem cell (MSCs) as the main source of stem cell for therapy show that MSCs have the potency to differentiate into NSCs. in vitro, a differentiation process from MSC to NSC has been developed by combining the supplement or growth factor needed in the culture media.Keywords: stem cells, neuron stem cell, mesenchymal stem cell, stroke, trans-differentiation

Authors: Patra Deepak Kumar , Pradhan Chinmay , Patra Hemanta Kumar
Published: September 2018

The pot culture experiments were carried out to study the toxicological changes in Lemongrass plants grown in varied percentage of Cr rich Over Burden Soil (OBS) with or without chelators such as Ethylene Diamine Tetra Acetic Acid (EDTA), Diethylene Triamine Penta Acetic Acid (DTPA), Citric Acid (CA), Salicylic Acid (SA) and metal ions (Zn and Mg). The toxicological impact of Cr on treated plants with reduced Transportation index (Ti) values indicated more root Chromium accumulation as compared to shoot. Shoot translocation of Cr as depicted by transportation index (Ti) values for different crops were enhanced with the application of chelating agents. The Bio-Concentration Factor (BCF) and Total Accumulation Rate (TAR) of Chromium were elevated with the supplementation of chelators and metal ions, thus, illustrated more metal bioavailability in plants.

Hoy en día, entre las principales temáticas asociadas a las enfermedades infecciosas destaca la referente a la detección y caracterización de los factores que confieren patogenicidad a los diversos agentes etiológicos, en razón de que los hallazgos implicados pueden conducir a la elaboración de vacunas eficaces. Sin embargo, es indispensable que los estudios correspondientes se realicen a ritmos mucho más intensos, habida cuenta que, en los últimos lustros, la competencia entre la resistencia bacteriana a los antibióticos y el descubrimiento o desarrollo de nuevos antimicrobianos, se ha venido resolviendo categóricamente a favor de los agentes patógenos (Garza, 2000; Salyers, 2002).

La enseñanza de las ciencias en el nivel universitario y preuniversitario está actualmente en un proceso de desarrollo y cambio en todo el mundo (Tiberghien et al., 1998; Gil Pérez y Vilches, 1999). Éste se debe, en parte, a las evidencias aportadas por la investigación sobre el fracaso generalizado de buena parte del alumnado en el aprendizaje de las ciencias, y también a las demandas planteadas por la sociedad a una educación que debería favorecer una alfabetización científica del ciudadano de este nuevo milenio (AAAS, 1989), y una preparación para la nuevas necesidades de los puestos de trabajo en un contexto caracterizado por una disminución de las tareas rutinarias (paulatinamente automatizadas) y un aumento de las destrezas de alto nivel intelectual.
Incompletitud. Rebecca Goldstein. Incompleteness: The proof and paradox of Kurt Gödel
Authors: Bedolla Carlos Amador
Published: September 2018

El teorema de Gödel es quizás el teorema más famoso de las matemáticas. Justamente, su fama deriva de su importancia, al haber modificado revolucionariamente el conocimiento existente y abrir rutas nuevas e insospechadas para su desarrollo posterior. Sin embargo, el teorema de Gödel es tan complejo, que incluso enunciarlo es difícil. Esto ha provocado, comprensiblemente, que tan famoso teorema sea frecuentemente malinterpretado.

Published: September 2018

Con este número hemos iniciado los festejos del vigésimo aniversario de Educación Química. Ello quiere decir que con el próximo número se empezará a producir el volumen 20 de nuestra querida revista. Ésta tuvo su primera aparición en el mes de julio de 1989, con su ya famoso número CERO, y comenzó con el año 1990 el primer volumen ordinario. De esta manera, concluyendo 2009 habremos publicado ¡ochenta y tres números! debido a los cuatro anuales más otros tres extraordinarios que han aparecido (en el año 1998 aparecieron seis ejemplares, cuando intentamos cambiar nuestra periodicidad, a cambio de que en el 2000 sólo aparecieron dos, debido a la huelga en la UNAM). Total, que dentro de cuatro años habremos llegado a la centena, porque el año entrante vamos a publicar otro número extraordinario con las ponencias magistrales de la VIII Convención de la Academia Mexicana de Profesores de Ciencias Naturales.

SummarySago palm (Metroxylon sagu Rottb.) isusually propagated vegetatively by suckers.However, the limited availability of uniformsuckers is a major obstacle in the establishmentof cultivated sago plantations. Tissue culture hasthe potential for large-scale mass clonalpropagation of superior genotypes of sago palm.In vitro culture of sago palm has been establishedthrough somatic embryogenesis. Embryogeniccallus derived from shoot apical tissue of youngsuckers was cultured on a modified Murashigeand Skoog (MMS) medium containing 30 g/Lsucrose, 2 g/L Gelrite, 1 g/L activated charcoal,5.0 mg/L 2,4-D, and 0.1 mg/L kinetin to inducesomatic embryos. Callus clumps formed somaticembryos within four weeks. In the subsequentculture, approximately 0.3 g initial globularcallus grown on MMS medium containing 1.0mg/L kinetin, 0.01 mg/L ABA and 0.1 mg/L GA 3produced 140 to 200 somatic embryos at differentdevelopmental stages four weeks later. All stagesof developing embryos with different sizesand colors were present at any one time ofculture. Secondary (repetitive) somatic embryo-genesis was also found in the culture.Transferring of the mature stage of somaticembryos to solid media with half-strength macro salts and with sucrose at concentration of 20 or 30 g/L without growth regulators led to the development of normal plantlets.RingkasanTanaman sagu (Metroxylon sagu Rottb.)biasanya diperbanyak secara vegetatif dengantunas anakan. Namun, terbatasnya ketersediaantunas anakan yang seragam merupakanhambatan utama dalam pembukaan perkebunansagu. Teknologi kultur jaringan mempunyaipotensi untuk perbanyakan klonal tanaman saguunggul dalam skala besar. Kultur in vitrotanaman sagu telah dikembangkan melaluiembriogenesis somatik. Kalus embriogenik yangberasal dari eksplan pucuk tunas anakandikulturkan pada medium modifikasi Murashigedan Skoog (MMS) dengan sukrosa 30 g/L,Gelrite 2 g/L, arang aktif 1 g/L, 2,4-D 5 mg/Ldan kinetin 0,1 mg/L untuk menginduksi embriosomatik. Kalus membentuk embrio somatikdalam waktu empat minggu. Dalam kulturberikutnya, dari kurang-lebih 0,3 g embrio faseglobuler yang dikulturkan pada medium MMSdengan kinetin 1,0 mg/L, ABA 0,01 mg/L danGA 3 0,1 mg/L menghasilkan 140 sampai 200embrio somatik dengan fase perkembangan yangberbeda-beda. Embrio somatik dalam semuafase perkembangan dengan ukuran dan warnayang berbeda-beda ditemukan setiap saat dalamkultur. Di samping itu, embriogenesis somatiksekunder (berulang) juga terjadi dalam kultursagu. Embrio somatik fase dewasa biladipindah ke medium padat dengan garam makrosetengah konsentrasi dan sukrosa padakonsentrasi 20 atau 30 g/L tanpa zat pengaturtumbuh akan menjadi planlet normal.

Summary The treatment of concentrated-latex effluent process applied in the field presently, has not obtain optimum additional benefits. Besides that, the technology using ponding system  needs  wide area and causes air pollution that  such a way caused conflicts with society. The application  concept of clean industry: reuse, reduction, recovery and recycling, makes the possibilities to convert the effluent to be usefull products. One of the alternative effluent process is by utilizing it as the source of renewable energy, that is in the form of biogas as an  alternative energy. The preliminary research showed that the use of spontaneous latex skim coagulation, the  addition of 1% manure as source of seed, and leaf biomass as the source of carbon could increase the biogas production. This research was carried out to optimize biogas production by adding metal ion and to observe the parameters which influenced every stage of biogas production. At the beginning of the process, pH showed increasing due to the hydrolysis process that generally occured in acid condition, but it remained stable (6.6-7.7) in the next steps, whereas, the VFA value as well as BOD value tended to increase. COD value had fluctuative inclination caused by the conversion of organic compounds to produce biogas and the hydrolysis process of leaf biomass to organic compounds that decom-posed to further biogas. The best result of biogas production was showed by addition of Fe3+ with optimum concentration 0.50 mg/L effluent.

IAA could be produced bysome rhizosphere microbes that could grow onlatex effluent using L-tryptophan (Trp) as itsprecursor. The aim of this research is todetermine potential growth and capability of IAAproduction by Rhizobium spp. R6 and KT onsynthetic and latex serum media supplementedwith pure Trp and with litter poultry manure as acheap source of Trp. The research coveredexamination of IAA producing Rhizobia usingliquid synthetic media supplemented with 0.07g/L and 0.14 g/L Trp. The potential Rhizobiumsp. in producing IAA was then inoculated intolatex serum media supplemented with pure Trpand Trp from litter poultry manure. Result of theresearch showed that the highest IAA productionwas reached as much as 51.08 µg/mL in syntheticmedia supplemented with 0.14 g/L Trp inoculatedwith Rhizobium sp. R6. IAA could be producedas much as 6.63 µg/mL in pasteurizedundiluted latex serum media supplemented with0.14 g/L Trp. Using latex serum mediasupplemented with Trp from litter poultry manureshowed that Rhizobium sp. R6 could produce11.91 µg/mL. Supplementation of pure syntheticTrp in IAA production could be replaced withlitter poultry manure as a cheap source of Trp.AbstrakPemanfaatan limbah lateks menjadi produkbio seperti asam indol asetat (IAA), dapatmengurangi volume limbah, menekan biayapengolahan limbah, serta menghasilkan produkyang bernilai ekonomis.

AbstractVegetable oil enriched with diacylglycerol (DAG) isknown as healthy oil. This oil is much more expensive thancooking oil. Production of DAG could be performed byglycerolysis process of CPO using specific lipase of 1,3-glyceride from Rhizopus oryzae mold. Product derived fromglycerolysis process of CPO is a mixture of DAG, mono-acylglycerol (MAG), free fatty acid (FFA) and residual ofunglycerolysed triacylglyserol (TAG). Therefore the DAGproduct has to be isolated from other components in order toget high purity of DAG. The objective of the research was topurify and to find out optimal concentration of DAG derivedfrom a mixture product of CPO glycerolysis at laboratoryscale experiment (total reactant for glycerolysis was93.8 mL) and semipilot scale experiment (10 times oflaboratory scale) using column chromatography with silicagel as stationary phase. The research showed that thehighest DAG content could be collected at fraction of 26 th i.e65%, while at semipilot scale experiment the highest contentof DAG (97%) was achieved at 64 to 66th fraction.Reglycerolysis of residual CPO only yielded 8.24%glycerolysis product which was much lower than that of thefirst glycerolysis reaching 46.67%. The highest DAG derivedfrom the second reglycerolysis product was achieved at 24 thfraction reaching 35.71 % .AbstrakMinyak nabati kaya kandungan diasilgliserol (DAG)dikenal sebagai minyak sehat (healthy oil). Minyak ini jauhlebih mahal dari minyak makan biasa. Produksi DAG dapatdilakukan dengan proses gliserolisis CPO menggunakanenzim lipase spesifik 1,3-gliserida dari kapang Rhizopusoryzae. Produk gliserolisis CPO triasilgliserol adalahcampuran DAG, monoasilgliserol (MAG) dan asam lemakbebas (ALB) serta residu triasilgliserol (TAG) yang tidaktergliserolisis. Oleh karena itu DAG yang terbentuk harusdipisahkan dari komponen lainnya agar diperoleh fraksi DAGdengan kemurnian tinggi. Penelitian ini bertujuan untukmemurnikan dan menetapkan konsentrasi DAG yang dapatdiperoleh dari gliserolisis CPO skala lab (total reaktan93,8 mL) dan skala semipilot (10 kali skala laboratorium)dengan kromatografi kolom menggunakan fase padat silikagel. Residu TAG dari gliserolisis pertama digunakan untukgliserolisis kedua atau gliserolisis ulang. Hasil penelitianmenunjukkan bahwa fraksi DAG dengan konsentrasitertinggi diperoleh pada fraksi ke-26 yaitu sebesar 65%,sedangkan pada percobaan dengan skala semipilot (10 kaliskala laboratorium) diketahui bahwa konsentrasi DAGtertinggi (97%) diperoleh pada fraksi ke-64 sampai denganke-66. Gliserolisis kedua dari residu CPO hanya mampumenghidrolisis TAG menjadi campuran DAG, MAG danALB sekitar 8,24%, lebih kecil dari reaksi gliserolisispertama yaitu sebesar 46,67%. DAG tertinggi yang berhasildikumpulkan dari produk gliserolisis kedua adalah padafraksi ke-24 yaitu sebesar 35,71% .
