Authors: Sahin D.Bahar , Tasdemir Fazilet
Published: December 2016

Universities are top institutions among education organizations. The personality types of academicians employed in these organizations are very important in terms of their own development and the development of the students they educate. The aim of this study is to examine the relation between personality types of academic staff and gender, mother education level and father education level variables. The research model is relational scanning. While determining the research group, teleological sampling method was selected among non-random sampling methods. The research was conducted through data obtained from 67 academic staff employed in different universities of Turkey during 2011- 2012 academic year. As data collection tool, “Holland vocational preference inventory” and “personal information form” were used. Chi square (x 2 ) test was performed in order to determine whether personality types of academic staff vary according to gender, mother education level and father education level.It was observed that the personality types of academic staff do not demonstrate significant difference according to gender. (x 2 = 1.01 and p>0.05) It was found that personality types of academic staff have a significant relation with mother education level (x 2 = 9.29 and p<0.05) and father education level. (x 2 = 9.79 and p<0.05) In line with the research findings, it was noted that academic staff has a social personality type containing helpfulness, social cooperation, sincerity, patience and similar properties. The relation of academic staff personality types with mother and father education levels emphasize the importance of parent education in determination of preferences and interests. Related with determination of academic staff personality types, their relation with variables such as attitude towards profession, academic success and so on can also be checked.

The Relationship between Moral Maturity and Sense and Behaviors of Responsibility in Gifted Children
Authors: Karatas Yalcin , Sarıçam Hakan
Published: December 2016

The main objective of the present study is to investigate the relationship between moral maturity and sense and behaviors of responsibility in gifted children. The secondary objective of the study is to compare the levels of moral maturity, sense of responsibility and behaviors of responsibility of gifted students (GS) and those of students with average intelligence level (SWAIL). The relational survey model has been employed in the study. The data was collected from 200 SWAIL attending the 6th and 7th grades in primary education schools in Ankara and 200 GS attending ‘Science and Art Centers’ (Turkish: BILSEM). The Scale for the Moral Maturity and the Sense and Behaviors of Responsibility was used as the data collection tool. In determining the differences between variables, the Independent samples t-Test was used for the variables which demonstrate normal distribution depending on the Kolmogorov Smirnov coefficients being insignificant at the p<.05 level. The correlation analysis was used in order to determine the correlations between the variables. At the end of the study, GS were found to be more mature in moral terms and to have a higher sense of responsibility compared to SWAIL. In the study, a statistical significant positive correlation (p<.01) was observed between moral maturity and sense and behaviors of responsibility in GS. In addition, a positive correlation (p<.01) was determined between the sense of responsibility and the behaviors of responsibility.

A Discourse Analysis of Parents’ Attitudes Towards Their Children’s Gender in Turkey
Authors: Baykut Sibel , Rahimi Ali
Published: December 2016

Abstract Children’s gender is a very sensitive issue intertwined with a myriad of psychophysiological and sociopolitical parameters. It plays an important role in determining women‟s status in the household and men’s status within the male community at large.  In some societies, there is a stigma attached to female children. Giving birth to a baby girl or not having a son can lead to the feelings of shame , embarrassment, disillusionment and ignominy on the side of the parents , specially for the mothers who have to see  having sons as the signs of  prestige, popularity and glory. Strangely enough, the male dominated society treats sonless fathers as impotent! This propels the fathers to point the finger of accusation at their wives, an act which is manifested in abuse or pejorative disparaging discourse and forcing the wives to bear more children under duress. This study has been an attempt to shed some light on the interplay between love, gender, discourse, emotions and identity. The whole process of the interrelation between love, gender and behavioral patterns is surrounded by prejudice, hegemonic patriarchal discourse and cultural beliefs and value systems. This study aimed  to analyze the situation in Turkish families to see the extent to which children’s genders are intermingled with the parents’ and communit’s love towards them. Key words: Motherhood, Gender, Fatherhood, Love, Discourse, Patriarchal attitude, Identity,  Preference for male children.
Cognitive Behavioural Therapy (CBT) and Treatment of Paediatric Patients with Chronic Renal Disease
Authors: Ajasllari Jeta
Published: December 2016

The aim of this study was to evaluate the effectiveness of an intervention with CBT in patients with chronic renal disease. The study findings are in the context of previous researches and existing theories. Searches were done in the professional literature related to different chronic diseases and respectively with Chronic Kidney Disease in children and adolescents. Many paediatric chronic diseases are difficult to be managed because of the limitations caused by the disease itself; consequently, some of them need to be subjected to painful and difficult medical procedures as well. Respectively, for children diagnosed with CKD life changes completely because of limitations, mainly physical ones, due to the characteristics of the disease which require constant adaption as well as development of strategies to face the disease. Their behaviours must change accordingly as part of a new life of self-care. Cognitive-Behavioural Therapy is a psychological therapy, which has been investigated extensively and has been found as very effective to reduce psychological symptoms caused by the disease. This therapy integrates the modification of behaviour with the cognitive restructuring, the aim of which is to change the patientâ€™s unhealthy behaviours through cognitive and behaviour techniques.Â Keywords: children; chronic kidney disease; cognitive behavioural therapy

Authors: Önder Emine , Karatas Zeynep
Published: December 2016

The aim of the study is to develop a new scale, called the “Classroom Management Anxiety Scale for Candidate Teachers”. This study was carried out on three different groups consisting of university senior class students from Mehmet Akif Ersoy University in Turkey. The psychometric properties of the Scale (CMAS-CT) were analyzed by means of item analysis, exploratory factor analysis, confirmatory factor analysis (CFA) and internal consistency and split-half methods. The exploratory factor analysis (EFA) results demonstrated that the scale comprised five factors. As a result of the EFA, the factor loadings of 25 items in the five factors were found to vary between 0.39 and 0.85. These five factors explained 54% of the total variance. CFA results demonstrated that five dimensional model provides good fit as per obtained fit index values. The Scale (CMAS-CT)’s internal consistency coefficient total scale score was determined .89 and split-half reliability coefficient was determined part 1 .85 and part 2 .79. In conclusion, Classroom Management Anxiety Scale for Candidate Teachers can be used as a reliable and valid measure for Turkish university senior class students. Keywords: Classroom management, anxiety, classroom management anxiety, candidate teacher
IS THERE A RELATION BETWEEN SIBLING ABUSE AND GUILT AND SHAME?
Authors: Demirbas Hatice
Published: December 2016

The current study aims to investigate the relationship between the feelings of shame and guilt and sibling abuse role (victim or perpetrator). Two hundred and three university students from Gazi University participated in the study. A survey including Sibling Abuse Scale, Guilt and Shame Scale and the Life Events Checklist were given to the participants. Regression analysis done to reveal if any relationship exists between general feelings of shame and guilt and sibling abuse role while controlling for the negative life events. Going through negative experiences in life was associated with level of victimization and perpetration in the case of sibling abuse. Perpetrator role in sibling abuse significantly predicted the feeling of guilt even after controlling for the negative life experiences. When predicting the feeling of shame, after controlling for the negative life experiences, neither the level of perpetration nor the level of victimization was found to be significant. The results of the study demonstrated that the more the individuals abuse their siblings in the early years, the less they feel guilt in the early adult years. Also, individuals who were exposed to higher levels of earlier abusive behaviors from their siblings were less likely to feel guilt when compared to not abused siblings. The findings of the study are important for preventive interventions. Therefore, educationists and health providers have responsibility about public education about sibling abuse.

La percepción sobre el ciberacoso del profesorado de secundaria de la Región de Murcia
Authors: González Calatayud Víctor , Prendes Espinosa María Paz , López Pina José Antonio
Published: December 2016

El ciberacoso se ha convertido en uno de los principales problemas o riesgos en la red para los jóvenes. Los estudios hablan de hasta un 58% de estudiantes afectados por alguna forma de ciberacoso (Yang, Lin, y Chen, 2014). Sin embargo, pocos estudios se han centrado en conocer cómo perciben este problema los profesores, lo que llama la atención teniendo en cuenta que son los principales agentes, con los padres, para identificarlo e intervenir. Por ello, este estudio tiene como objetivo conocer la percepción del profesorado de secundaria en relación con el ciberacoso. Para ello se utilizó un cuestionario en inglés de una investigación previa y se utilizó el método de la doble traducción para su validación. Los resultados muestran que el profesorado subestima este problema. Además, admiten que no son capaces ni de identificar ni manejar los posibles casos de ciberacoso, aunque la mayoría llevaría a cabo alguna acción para detenerlo. Los profesores reclaman formación y una mejor orientación para el manejo de este problema, cuestión relevante que debe ser tenida en cuenta por las administraciones educativas y también por las universidades como responsables de la formación inicial de profesorado.

La competencia comunicativa es un elemento fundamental en la formación de los futuros profesionales de la docencia y esta debe ser trabajada de manera transversal desde las diversas materias que conforman los planes de estudios, especialmente, en aquellas en las que el alumnado deba desarrollar conocimientos, habilidades y destrezas asociadas a ella. En esta línea, surge la experiencia de innovación educativa basada en modulación de las metodologías que han permitido la coordinación interdisciplinar, en el curso académico 2014-2015, de las asignaturas “Formación literaria y Literatura infantil” y “Educación Mediática y aplicaciones didácticas de las TIC”, que se imparten en segundo curso del Grado en Educación Primaria, en el Centro de Magisterio Sagrado Corazón (Universidad de Córdoba). Se diseñó una práctica de narrativa audiovisual, cuyo punto de partida fue la selección de las competencias y la formulación de los objetivos a alcanzar. Teniendo en cuenta la interactuación interacción de los diversos aprendizajes adquiridos por el alumnado en las distintas materias, se planificaron las metodologías, la secuenciación y la temporalización de las diversas fases de la práctica, así como la guía y los instrumentos de evaluación, tanto del logro de las competencias como de la satisfacción del alumnado con la experiencia. Los resultados obtenidos evidencian que la realización de este tipo de prácticas coordinadas favorece la adquisición y movilización de las competencias asociadas al Título.

THE GENOTYPES X ENVIRONMENT INTERACTION FOR STARCH YIELD IN NINE-MONTH OLD CASSAVA PROMISING CLONES
Authors: Sholihin Sholihin
Published: December 2016

Cassava (Manihot esculenta) is planted in dry areas with different environmental conditions, therefore the yield is varied. The aim of the study was to analyze the genotype x environment interaction for starch yield in 9-month old cassava promising clones. The experiment was conducted on mineral soils in four different locations, i.e. Lumajang-East Java (Inceptisols), Kediri-East Java (Entisols), Pati-Central Java (Alfisols), and Tulangbawang-Lampung (Ultisols) during 2004- 2005. The experiment was arranged in split plot design with three replications. The main plots were cultivation techniques, i.e. simple technology and improved technology, whereas the subplots were 15 cassava promising clones. Starch yield of 9- month old cassava plants was analysed using the additive main
effects and multiplicative interaction (AMMI). The results showed that environmental factors determined the stability of starch yield were soil bulk density on subsoil, the number of rainy days at fifth month, minimum air temperature at fourth month, and minimum air humidity at seventh month. CMM97002-183, Adira 4, CMM97007-145, CMM97007-235, Malang 2, CMM97002-36, and CMM97006-44 were identified as the stable cassava clones for starch yield in 9-month old. Average starch yield of Adira 4 was the third after MLG 10311 and CMM 97006-52. The CMM97006-52 was adapted to the soils having high P2O5 content on topsoil, high minimum air temperature at 4 and 5 months after planting, high minimum relative humidity at 7 months after planting, low total rainfall at 5 months after planting, and low number of rainy days at 5 and 8 months after planting. MLG 10311 was adapted to low soil bulk density. The average starch yield of MLG 10311 was the highest at 9 months after planting. The study implies that advanced trials for CMM 977006-52 and MLG 10311 clones are needed, so the clones can be released as new varieties of cassava. In selection and evaluation, the bulk density on subsoil is needed to be attained specifically to increase the probability to obtain new variety of cassava.
SOYBEAN SEEDLING ROOT GROWTH PROMOTION BY 1-AMINOCYCLOPROPANE-1-CARBOXYLATE DEAMINASE-PRODUCING PSEUDOMONADS
Authors: Husen Edi , Wahyudi Aris Tri , Suwanto Antonius , Saraswati Rasti
Published: December 2016

Pseudomonad producing 1-aminocyclopropane-1-carboxylate (ACC) deaminase (E.C.4.1.99.4) has been known to promote plant growth by lowering ethylene biosynthesis in higher plants, which can be induced by indole-3-acetic acid (IAA) production. The objective of this study was to examine the ability of IAAproducing Pseudomonas isolated from local soil environment (rhizosphere of soybean grown in Plumbon's agricultural area
in Cirebon, West Java, Indonesia) to promote soybean root growth in relation to their ACC deaminase activities. The experiments were conducted in growth room and Laboratory of Soil Biology Research, Indonesian Soil Research Institute, Bogor, from January to August 2008. Soybean seeds were inoculated by immersing the seeds for 1 hour in bacterial cell suspension containing approximately 108-109 cells ml-1. The seeds were then germinated
for 2 days before planting in growth pouches containing sterilized distilled water. All treated and untreated seeds were grown for 7 days in growth room at 24°C with 1300 lux of light intensity for 12-hour followed by a 12-hour dark period at 22°C. ACC deaminase activity of the isolates was assayed based on their ability to grow in Dworkin-Foster’s salt minimal medium containing ammonium sulfate or ACC as a source of nitrogen. Thirteen out of 81 isolates tested significantly increased soybean root length and weight, up to 50% from untreated plants. Of 13 isolates, 11 demonstrated ACC deaminase activities. Two isolates that did not show ACC deaminase activities had lower capacity to produce IAA. The results suggest that the effectiveness of IAA producing Pseudomonas in promoting the growth of the soybean seedlings is associated with their ACC deaminase activities or they produce IAA at low levels.
CHARACTERISTICS OF COMPOSTED BIO-TOILET RESIDUE AND ITS POTENTIAL USE AS A SOIL CONDITIONER
Authors: Triastuti Jovita , Sintawardani Neni , Irie Mitsuteru
Published: December 2016

Bio-toilet is a dry toilet where human excreta is trapped in a lignocelluloses soil matrix such as wood sawdust, then it is decomposed by aerobic  bacteria to organic compost rich in minerals such as N, P, and K. The study aimed to characterize the bio-toilet residue and its potential use as a soil conditioner for Jatropha curcas. The study was conducted in a private school of Daarut Tauhid in Bandung West Java. A bio-toilet S-50 type of Japan was constructed consisting of a composting chamber, mixer, heater, exhaust fan, and closet. The composting chamber was filled with 63 kg of Albizzia sawdust. Feces and urine was loaded daily by 54 students for 122-day observation. At the end of observation, the decomposed bio-toilet residue was evaluated for its physical properties such as bulk density (rb), porosity (%), and water retention (WR). Chemical properties such as pH, C/N ratio, N, P, and K, as well as microbiological properties such as numbers of bacteria, fungi, and worm eggs were evaluated at 14 and 122 days of decomposition process. Effect of the composted bio-toilet residue as plant growth media was evaluated using J. curcass as a plant indicator. Before it was used as a growth media, the composted bio-toilet residue was dried in a room temperature for 30 days. The experiment was designed in a completely randomized design 2 x 4 factorial with three replications. The first factor was the rate of composted biotoilet residue, i.e., 0, 20, 40, and 60% based on weight of the growth media mixture (1500 g pot-1), and the second was NPK fertilizer addition at 0 and 2 g pot-1. Each pot was planted with 2-month old of J. curcas seedlings. Parameters evaluated were leaf number, leaf area, stem height, and stem diameter measured at 12 weeks after planting. The results showed that the biotoilet residue was suitable as soil conditioner because it had high porosity (76%), low bulk density (0.19 g cm-3), high water retention (2.6 ml g-1 DM), neutral pH (6.9), C/N ratio 27, and contained N, P, K, and Na of 1.73, 1.15, 1.03, and 0.88%, respectively. Its microbial count showed only two kinds of bacteria, i.e., Klebsiella pneumonia and Escherichia coli, detected at 14 and 122 days of bio-toilet usage. The composted bio-toilet residue improved vegetative performances of J. curcas as indicated by increasing leaf number, leaf area, stem height, and stem diameter.
PROTOPLAST FUSION BETWEEN WHITE AND BROWN OYSTER MUSHROOMS
Authors: Djajanegara Ira , Masduki Agus
Published: December 2016

Genetic crossing of white oyster mushroom (Pleurotus floridae) to introduce longer storage life trait can only be done within individuals in this particular species. However, longer storage life trait is possessed by brown oyster mushroom (Pleurotus cystidiosus). Therefore, a protoplast fusion experiment between white and brown oyster mushrooms was conducted to obtain an oyster mushroom strain showing high productivity and long storage life. The experiment was done at the biology laboratory of the University of Al Azhar Indonesia from May 2008 to August 2009. Protoplast fusion was done by isolating protoplast from 5-day old monokaryotic mycelia grown in potato dextrose broth (PDB). Around 3.15 x 105 protoplasts ml-1 were harvested using mixture of cellulase Onozuka R-10 (1%) and macerozyme R-10 (1%) from brown oyster mushroom with 80.61% viability. Similarly, 3.71 x 105 protoplasts ml-1 were harvested using lysing enzyme (2%) from white oyster mushroom with 83.68% viability. Protoplast fusions were conducted using 40% PEG6000 for 10 minutes. The candidate fusants were then screened using minimum regeneration media (MRM). There were 22 colonies grew on MRM media and four colonies (FS1, FS2, FS3, and FS4) showed clamp connection as well as primordia formation to be chosen as candidate fusants. However, isozyme studies using malate dehydrogenase and acid phosphatase as marker enzymes confirmed that only FS1 and FS2 were the hybridized products. The two colonies showed different mycelia growth patterns and hyphae sizes, fruit body morphology and productivity compared to their parents. These two fusants, however, did not indicate the presence of longer storage life trait as expected despite a higher productivity achieved by FS1. In this study, the protoplast fusion only yielded higher productivity strain of mushroom with different colors without any changes in storage life.

Integrated crop management (ICM) is a combination of water, crop, and nutrient management that optimizes the synergistic interaction of these components aiming at improving resource use efficiency, i.e. high productivity of water, land, and labor. The objectives of the study were to investigate the effects of crop establishment method, organic matter amendment, NPK management, and water management on yield of lowland rice. Five series of experiments were conducted at Sukamandi and Kuningan Experimental Stations, West Java. The first experiment was focused on crop establishment method, i.e. plant spacing and number of seedlings per hill. The second, third, and fourth experiments were directed to study the effect of NPK and organic matter applications on rice yield. The fifth experiments was designed to evaluate the effect of water management on rice yield. Results showed that 20 cm x 20 cm plant spacing resulted in the highest grain yield for the new plant type rice varieties. Organic matter and P fertilizer application did not significantly affect grain yield, but the yield response to P fertilization tended to be stronger with organic matter amendment. Split P application did not significantly increase grain yield. The use of a scale 4 leaf color chart reading resulted in a considerable N fertilizer saving without compromising rice yield. Intermittent irrigation technique saved water up to 55% without affecting yields, resulting in a 2-3 times higher water productivity.

Increasing price of soybean becomes a serious problem for producers of traditional foods such as tempeh and tofu. These traditional foods are important protein sources for many Indonesian people. Tribal bean (Canavalia virosa) could be used as a substitution of soybean for tempeh and tofu processing. This study aimed to determine physico-chemical characteristics of tribal bean and its products such as tofu and tempeh. Tribal bean old pods were peeled manually in the Postharvest and Agricultural Machinery Laboratory of the Yogyakarta AIAT. The peeled seeds were dried until 10% water content and their epidermis were removed mechanically by using an abrasive peeler to produce yellowish clean peeled beans. The beans were analyzed physically and chemically using the standard prosedure. Since the tribal bean seeds contained high HCN, to minimize HCN content the beans were presoaked for 48 hours in water. The beans were then mixed with soybean at a ratio of 50:50 or 25:75 and processed for making tempeh and tofu using traditional method. Physicochemical and organoleptic characteristics of the tribal bean tempe and tofu were analysed, involving organoleptic test with hedonic method, texture, as well as water, ash, protein and crude fiber contents. The results showed that tribal bean contained protein (37.30%), essential amino acids, minerals and fiber (3.1%), and a toxic substance HCN. Presoaking the beans in water for 48 hours significantly reduced HCN content by 98.51%, from 1334 ppm. Tofu made of a mixture of tribal bean and soybean at a ratio of 25:75 plus 2% rice vinegar as a coagulant has a white color and normal flavor appearances, and was accepted by panelists. The tribal bean tempeh contained 78.1% water, 1.21% ash, 8.14% protein, 3.1% crude fiber, and 44 ppm HCN. Tempeh made of a mixture of tribal bean and soybean at ratios of 50:50 and 25:75 showed good characters (flavor, taste, color, and texture) and panelist acceptance, as well as nutrition values (76% water, 2.71% ash, 14% protein, 0.25% crude fiber, and 14% lipid). However, HCN content in the tofu was still higher (85 ppm HCN) than the recommended maximum value of 50 ppm. This study suggests that tribal bean is more suitable for tempeh than for tofu based on its HCN content.

Late blight resistance gene (RB gene) isolated from Solanum bulbocastanum, is a broad resistance gene against all races of Phytophthora infestans. The gene was transformed into Katah-din event SP904 and SP951 using Agrobacterium tumefaciens and these transgenic plants have been crossed with susceptible potato cultivars Atlantic and Granola. Populations of the crosses have been molecularly characterized for the integration of the RB transgene. The study aimed to evaluate the resistance of the populations of crosses between transgenic Katahdin RB  and susceptible non-transgenic parents (Atlantic and Granola) to late blight in a confined field trial at Pasir Sarongge, Cianjur, West Java. A total of 84 clones originated from four popula-tions were evaluated for resistance to late blight. These included 22 clones of Atlantic x transgenic Katahdin SP904, 16 clones of Atlantic x transgenic Katahdin SP951, 19 clones of Granola x transgenic Katahdin SP904, and 27 clones of Granola x transgenic Katahdin SP951. Observations of the late blight infection were conducted when late blight symptoms were detected, i.e. at 56, 60, 63, 70, and 77 days after planting (DAP). The result showed there were high variations in the resistance level of all the 84 clones tested. Clones of crosses between susceptible parents (Atlantic or Granola) and resistant parents (transgenic Katahdin SP904 or Katahdin SP951) showed a similar pattern based on the area under disease progress curve (AUDPC) value, i.e. 377.2 greater than the AUDPC of the resistant parents (180.1), but smaller than that of the susceptible parents (670.7). Observation at 77 DAP resulted four resistant potato clones having resistance score of 7.0-7.6, higher than the transgenic parents Katahdin SP904 (4.6) and Katahdin SP951 (6.8), i.e. clone B8 (Atlantic x transgenic Katahdin SP951) with resistance score of 7.6 and clones B26 (Atlantic x transgenic Katahdin SP951), C183 (Granola x transgenic Katahdin SP904), and D89 (Granola x transgenic Katahdin SP951) with resistance score of 7. These four transgenic potato resistant clones need to be further developed as promising potato clones to late blight.

Indonesia placed the fourth biggest diabetics in the world after India, China, and the USA with prevalence amounting to 8.6% of the population. Diabetes is an abnormal carbohydrate metabolism. Therefore, nutrition plays a key role in the management of the disease. This study aimed to find hypoglycemic sweet potatoes and appropriate processing to create low glycemic foods. Eight Indonesian sweet potato varieties/clones were used in this experiment, i.e. Kidal, Sukuh, Sari, Ungu, Jago, BB00105.10, B0464, and BB00106.18. Samples were firstly analyzed for their physicochemical and nutritional properties, which then followed by evaluation of their hypoglycemic responses. The selected variety was processed into three different basic processing methods, i.e. boiling, baking, and frying, and then their glycemic indexes (GI) were evaluated. Result showed that among eight sweet potato varieties/clones studied, BB00105.10 clone indicated the best hypoglycemic response. The highest hypoglycemic activity was supported with the highest resistant starch content (3.8%), protein content (5.47%), and low starch digestibility (51.4%). The sweet potato tubers contained medium to high amylose (24.94%). Processing methods influenced the GI value of foods. Fried sweet potatoes had the lowest GI (47), followed by the boiled one (GI = 62) and the baked one (GI = 80).

Grain quality and aroma are important characteristics of rice that affect consumer acceptance. This research was conducted to study the grain quality and aroma of aromatic new plant type (NPT) promising rice lines. Thirty five lines as well as Ciherang and Sintanur varieties were planted at Bogor and Pusakanagara, West Java in the dry season (DS) 2009 and wet season (WS) 2009. Three methods, i.e. leaf aroma tested with KOH, rice aroma tested in the test tube, and cooked rice aroma test, were used to evaluate the aroma of the lines. The results showed that line B11742-RS*2-3-MR-34-1-2-1 was aromatic identified using different methods. The line had long, slender, and small chalkiness grains, high percentage of head rice, high amylose, and hard texture. Lines IPB 140-F-6, B11249-9C-PN-3-3-2-2-MR-1, and B11955-MR-84-1-4 also had a high aroma score and grain yield. Testing leaf aroma with KOH can be used as early selection method in breeding program for aromatic lines. Lines derived from aromatic parents from highlands of South Sulawesi did not show consistent aroma under three testing methods. Those tested lines had good grain quality, both physical and cooked rice quality.

Azospirillum sp. have long been known as biofertilizer for plant growth because of its capability to produce phytohormones and fix nitrogen from the atmosphere. Multifunctional Azospirillum strain Aj Bandung 6.4.1.2 isolated in 2009 from cauliflower (Brassica oleracea) rhizosphere in Lembang, Bandung, West Java, was capable of fixing nitrogen, solubilizing tricalcium-phosphate, and producing phytohormone indole acetic acid (IAA). The study aimed to modify the multifunctions of Azos-pirillum sp. for better capability of fixing N2, solubilizing P, and producing IAA using ethyl methanesulfonate and 1-methyl-3-nitro-1-nitrosoguanidine (EMS) mutagen. The study was conducted at Indonesian Center for Agricultural Biotechnology and Genetic Resources Research and Development (ICABIOGRAD) in 2010. The results showed that this strain was genetically mutagenized using EMS for better performance in solubilizing P, fixing N2 (nitrogenase activity), and producing phytohormone (IAA). The optimum concentration and the length of incubation time for the process have been determined. Nine selected mutants with increasing capability to solubilize P (determined by clear-zone formation on Pikovskaya’s medium) have been characterized for nitrogenase activities and IAA production compared to wild type Aj Bandung 6.4.1.2. The effect of mutagenesis on IAA produc-tion and nitrogenase activities varied among the mutans. Two mutants, AzM 3.7.1.16 and AzM 1.7.2.12, showed superiority in the production of IAA, while two mutants, AzM 1.5.1.14 and AzM 3.7.1.15, were superior in nitrogenase activities. The EMS mutagenesis of Azospirillum sp. showed enhanced dissolving capa-bility of unsoluble phosphate (tricalciumphosphate) and increased IAA production and nitrogenase activity.
