MUHAMAD SYUKUR,SRIANI SUJIPRIHATI,RAHMI YUNIANTI,UNDANG
HAYATI Journal of Biosciences , 2010,
Abstract: One method to obtain genetic information is the diallel cross analysis. The objective of this study was to eavluate the genetic parameters of six inbred pepper (Capsicum annuum L.) using full diallel crosses. The experiment was conducted at IPB Experiment Field, Cikabayan, Darmaga. The design was randomized complete block design (RCBD) using three replications as blocks. Data from generation F1 and parents were analyzed using the Hayman Method. Results indicated that no epistatic effects were significant for all the traits assessed. Additive genetic effects were larger than the dominant effects for yield per plant, fruit length, and diameter fruit traits. Dominant genetic effects were larger than the additive effects for fruit weight traits. Narrow-sense and broad-sense heritability were high for all the traits assessed. The character of the yield per plant, fruit weight and fruit diameter shows that there were more dominant genes in the parents. There were more recessive genes in parents for the fruit length character. IPB C7 parent was the most recessive genes containing control characters in the yield per plant. In the new improved varieties of high yielding, IPB C7 could be crossed with IPB C9. Employing individual or mass selection breeding should be successful in developing high-productivity lines in this population.

HAYATI Journal of Biosciences , 2011,
Abstract: Induction of genetic variant of Artemisia annua L. was conducted through the application of gamma ray irradiation in 2007-2008. The aim was to obtain a plant with high artemisine content > 0.5% and late flowering period of about > 7 month after planting. Tweleve selected genotypes were subsequently examined to gain genetic stability on altitude of 1500, 950, and 540 m asl. The results showed that the plants had shorter flowering age in Cicurug (540 m asl) than that of in Pacet (950 m asl) and Gunung Putri (1540 m asl). Genotype 8 had the latest age of flowering in the three locations than the other genotypes, however, the growth and biomass were the lowest. Vegetative growth of Artemisia in Pacet and Gunung Putri was better than those in Cicurug. Genotype of 15 in Cicurug and 5A genotype in Gunung Putri and Pacet had higher wet and dry weight than that of two other associates. Based on plant biomass, 5 genotypes from Gunung Putri and Pacet i.e. 1D, 3, 5A, 14, and 15 genotypes were selected, as well as 5 genotypes i.e. 1D, 3, 4, 5A, and 15 genotypes from Cicurug. Analisys on artemisin content successfully obtained 5 selected somaclone lines i.e. 1B, 2, 4, 14, and 3 somaclones.

Agrivita : Journal of Agricultural Science , 2011,
Abstract: The objective of this study was to identify the adaptability of twelve artemisia mutant genotypes, which were planted in three locations with different altitude, as a result of gamma irradiation. Randomized Complete Block Design (RCBD) was applied in this research with three replications as blocks. The genotypes 1B, 1C, 1D, 2, 3, 4, 5A, 6B, 7A, 8, 14, 15 and two control genotypes as parent genotype from seed and from in vitro were used. The genotypes were planted in three different locations such as Mount Putri, Cianjur (1450 m above sea level), Pacet, Cianjur (950 m above sea level) and Cicurug, Sukabumi (540 m above sea level). Based on the method of postdictive and predictive success, the model used was AMMI2 which was able to explain up to 100% of interaction-influenced variation. The genotypes which were found stabile and adaptive in these three locations were 1B, 1C, 1D, 6B and 15. Genotypes 3 and 7A were adaptive specifically in Pacet area, 5A was adaptive for Gunung Putri while genotype 4 was for Cicurug only.

Observations of Embryonic Changes in Middle and Late Stages of the Greater Wax Moth, Galleria mellonella (Lepidoptera: Pyralidae)  [PDF]
Muhamad Abidalla, Donatella Battaglia
Advances in Entomology (AE) , 2018, DOI: 10.4236/ae.2018.63015
Abstract: The embryogenesis of lepidopteran insects has morphogenetic events accompanying the blastokinesis movements (anatrepsis and katatrepsis) in early and late stages, respectively. Katatrepsis is related to embryonic movement with yolk mass and regression of amnioserosa folds in the second half of the development cycle. The whole mount method and differential interference contrast microscopy (DIC) were used for analysing the embryonic developmental changes. Those changes in the middle and late embryonic periods were described and divided into eight stages: 1) Completion of segmentation and differentiation of cephalic and thoracic appendages (32 - 40 hours post-oviposition h. PO); 2) Expanded growth of cephalo-gnathal and abdominal parts (41 - 60 h. PO); 3) Completion of thoracic appendages and appearance of pleuropodia, katatrepsis (60 - 70 h. PO); 4) Pre-revolution morphogenetic movement of the cephalo-gnathal region (71 - 80 h. PO); 5) revolution of the embryo (81 - 100 h. PO); 6) Beginning of dorsal closure (101 - 115 h. PO); 7) completion of dorsal closure (116 - 120 h. PO); and 8) full-grown embryo just before hatching (121 - 144 h. PO).

DJOKO PURNOMO,SYUKUR MAKMUR SITOMPUL
Biodiversitas , 2006,
Abstract: Teak and pines are the largest tree forests in Central of Java so that they are very potential to be developed as an argoforestry system. The average Relative Irradiation Fraction (RIF)’s in the teak and pines trees are 50% and 14% respectively. Meanwhile, soybean is sun-loving crop potentially to be cultivated in the agroforestry system. The aim of the research was to study the response of the soybean (Glyicine soya) varieties to the tree canopy pruning. The experiment was conducted at teak and pines forest area (vertisol and ultisol soil type respectively) arranged in split plot design. The main plot factor was pruning (no pruning and pruning) and the sub plot factor was variety (Wilis, Pangrango and Brawijaya). The teak and pines canopy pruning (50% lower part of canopy) increases the incident irradiation among the trees by 70%-89% or equal to 600-1000 mol m-2 s-1 and 80% or 840 mol m-2 s-1 respectively. The increase in the irradiation among the trees enhances the photosynthetic rate of soybean. The response of the soybean to the enhancing irradiation is higher in specific leaf area (SLA). Biomass production and seed yield of the soybean increases due to the canopy pruning. The seed yield of soybean increase respectively from 0.12 to 0.57 tons ha-1 and from 0.78 to 1.74 tons ha-1 in no pruning and pruning teak and pines agroforest. The Pangrango variety produces the highest yields of seed, thus it is potential to be cultivated as intercrops in a teak and pines agroforestry system.

Umi Mahmudah, Muhamad Safiih Lola
Open Journal of Statistics (OJS) , 2016, DOI: 10.4236/ojs.2016.66085
Abstract: The main objective of this study is to measure the relative efficiency of Indonesian universities in 2015. There are twenty five DMUs with four inputs and five outputs that are analyzed. Due to the low number of Indonesian scientific publications, this study analyses the performance of the top 25 universities based on the Webometrics ranking as it has been used as one of the indicators of university achievements by the Higher Education of Indonesia. The Data Envelopment Analysis (DEA) is used to obtain the scores of efficiency, while the Fuzzy approach is applied to address the possibility of errors from the auditor’s assessment in determining the input and output variables correctly. The FDEA can be used in measuring the universities performances under imprecise inputs and outputs. Both the CRS (constant returns to scale) and the VRS (variable returns to scale) models are presented. The empirical results show that 36 percent of universities perform efficiently on the CRS model while 52 percent of universities have efficient performances under the VRS model. Furthermore, the well-known universities have shown relatively low scores, which indicate they need to improve their performances in publishing scientific work, as well as providing useful information to the public through the official websites. Generally, the results of the VRS model are better than the CRS model for both the DEA and the FDEA methods.

Muhamad Abidalla, Pio Federico Roversi
Advances in Entomology (AE) , 2018, DOI: 10.4236/ae.2018.64017
Abstract: The increased importance of the G. mellonella for wide range of scientific research and commercial sides will need to create a germplasm resource banking by cryopreservation. Impermeability is a fundamental limiting factor for the successful cryopreservation of arthropods embryos. The successful permeability of Drosophila embryo by using an embryo permeabilization solvent (EPS) solution encouraged this trial on G. mellonella embryos (stage of 24 hours Post-oviposition (h PO)). Permeability assessment with Rhodamine B and crystal violet dyes showed that G. mellonella embryos can be permeabilized by EPS of D-limonene that has 3 mol ethoxylated alcohol. The permeabilization for 30 sec exposure time was resulted 61.5% ± 5.8% survival rate, 31.7% ± 3.1% uptakes dyes and 40.5% ± 0.3% was the survival rate post loading in 12% Ethylene glycol (EG). The low viability after immersion in liquid nitrogen (LN) (0.6% ± 0.08%) is due to the dual toxicity of EPS and cryoprotectant (CPA) solutions. However, fluorescence images showed sufficient permeability that confirms the possibility to increase the permeability of G. mellonella embryos with EPS solution, and to have the opportunity to improve the viability after LN by improving procedures of loading and dehydration with various CPAs and exposure times, which decrease the toxicity effect.

Sulakhudin,Abdul Syukur,Bambang Hendro Sunarminto
Jurnal Tanah Tropika , 2011,
Abstract: he growth and yield of plants are mainly a function of the quantity of fertilizer and water. In coastal sandy soil, nutrient losses and dry soils are seriously problems. The objective of the research was to study effect of zeolite and hucalci concentrations as NPK coating materials on NPK qualities i.e. water adsorption and release of N, P and K. The research used a coastal sandy soil as media. It was conducted in a laboratory of Soil Science Department, Gadjah Mada University from July to August 2009. Experimental design used was a factorial in a completely randomized design. The first factor was hucalci concentration, consisted of 10% (H1), 20% (H2), and 30% (H3). The second factor was zeolite concentration, consisted of 25% (Z1), 50% (Z2), 75% (Z3), and 100% (Z4). NPK fertilizer (without coating) used as a control. The results showed that hucalci and zeolite had a capability to increase water adsorption and to retard the release of N, P, K. The coated NPK with hucalci 30% and zeolite 100% had the highest quality in water absorption, water retention and release of nutrients.
