Abstract

Self-regulated learning is a constructive process that is active in setting learning goals. This ability should be possessed by every individual to become a successful learner. Another thing that students must have to be successful in the process and learning outcomes are learning motivation. This study aims to determine the correlation between learning motivation with self-regulated learning in grade X MIPA 9 SMA Negeri 1 Tasikmalaya City. This research was conducted in April 2019. The research method used was correlational with a population of all class X MIPA 9 students as many as 30 people. Samples were taken using a saturated sampling technique so that the entire population was sampled. The research instrument used in this study is the Motivated Strategies for Learning Questionnaire (MSLQ), which consists of 2 parts, namely motivational beliefs and self-regulated learning strategies. The data analysis technique used is the bivariate correlation regression test. Based on the results of the study, it can be concluded that there is a strong correlation (R = 0.761; R2 = 0.580) between learning motivation and self-regulated learning. The contribution of learning motivation to self-regulated learning is 58%.

Abstract

Screening to genomic library of soybean cultivar Slamet in ë phage to isolate the gene encoding for peroxidase(per) was performed by two steps. cDNA of per gene from Arabidopsis thaliana labeled by alkalin phosphatasewas used as probe. The first screening was done by using 105 recombinant pfu (plaque forming unit). The secondscreening was carried out on 100 recombinant pfu isolated from the first screening. The result of second screeningshowed that all screened clones were supposed containing per gene. The ë phage resulted from second screeningwas infected into E. coli BM 25.8. Due to the Cre recombinase in E. coli BM 25.8, two lox P sites flanking the insertDNA of soybean created recombination. The recombination in loxP sites resulted the excision and formedrecombinant plasmid containing per gene of soybean. To multiply, the recombinant plasmid was introduced into E.coli DH5á. Analysis southern hibridization of recombinant plasmid cut by Bam HI showed that Bam HI 3.7 kbfragmen of S52121R clone, 5,3 kb of S2412R clone, 2,4 and 5,3 kb fragments of S2532R clone were supposed tocontain per genes.

Abstract

Curcuma xanthorrhiza Roxb, which is well-known as Java turmeric, has been extensively used in pharmaceutical industries in Indonesia. In spite of this commercial value, the identity of this species is commonly mistaken from other similar orange rhizomes Curcuma. Correct identity of these species is vital in pharmaceutical industries. The objective of the study was to determine genetic diversity of 32 accession Curcuma xanthorrhiza Roxb. Genomic DNA was extracted from leaf using Sodium Dodesyl Sulphate (SDS) modification. Amplified fragment length polymorphism (AFLP) was carried out according to the protocol ofAFLPTM plant mapping kit and the final polymerase chain reaction (PCR) products were separated using The Agilent 2100 Bioanalyzer. The number of fragment produced by 12 pairs primer combination of AFLP ranged from 42 to 60 with an average of 52. Data obtained was analyzed by the NTSys program. From the AFLP amplification on 32 DNA samples, it was proven that the accession of Curcuma xanthorrhiza Roxb. had a high degree of diversity. Based on analysis of AFLP and unweighted pair group with arithme average (UPGMA) it was shown that the accession of Curcuma xanthorrhiza Roxb. could be grouped into two cluster at relative ecludian distance of 0.10 (10%).

Abstract

Availability of moleculer marker to identify the important agronomic character of plant is needed to accelerate selection activity of plant. Particularly for the complex quantitatively inherited traits - like e.g. shading tolerance of soybean - the use of such a technique will speed up the process to produce adapted genotypes.The objective of this research is to identify the linkage of molecular marker RAPD with character of shading tolerance. The morphological specific characters wich is corelated to shade tolerance is the number of productive branchs. The intensity 75% of artificial shading is optimal level for doing selection of soybean genotypes. The inheritance of shading tolerance of soybean was controlled by gene with full dominant or by two genes pairs with dominant and ressesive epistasis. There was no maternal effect in the inheritance to shade tolerance. Heritability value (0.45 – 0.54) indicated that the proportion variation caused by the genetic factors was moderate. Molecular analysis by using RAPD technique showed that UBC153, ROTH 480.01, and ROTH 480.03 primer have polymorphic band that can be used for inheritance study and linkage analysis. All polymorphisms segregated independently of each ather. Interval mapping with Mapmaker/QTL indicated that the location of the three QTLs on linkage group were at marker tolerance locus of Roth 480.01-8125 , Roth 480.03-1125, and UBC 153-19125 .

Abstract

The efficacy of entomopthogenic fungus for Tussock Moth Caterpillars Control. The occurrence of Tussock Moth Caterpillar (TMC) out break reported in some areas in East Java at Probolinggo, Malang, Batu and other districts were worried. The high caterpillar population not only attacking mangos, cherry, and wild watercress, but also migrating to living house before pupation. The available control of these caterpillar is chemical pesticide. However, thechemical will kill the natural enemies and other beneficial insects. A laboratory experiment to study the efficacy of five entomopathogenic fungus against TMC and pupae was conducted at the Entomology Laboratory of Indonesian Legumes and Tuber Crops Research Institute (ILETRI) in April 2011. Our experiment was arranged using completely randomized design (CRD) with three replicates using five entomopthogenic fungus. The efficacy was determined by the mortality of caterpillar/larva and pupae infected by the fungus. Result showed that these five fungus had not effectively kill the caterpillar, as the dense setae in integument acted as a mechanical barrier to fungus infection. The pupal stage was more susceptible to fungus infection. It was found that Paecilomyces fumosoroseus and Lecanicillium lecanii fungus were more effective than Metarhizium anisopliae, Beauveria bassiana and Nomuraea rileyi repectively. These two fungus could kill 90% of pupae and also were easier to be cultured in a wide range of natural media. Therefore P. fumosoroseus and L. lecanii are potentially used as a biological control agent against TMC out break.Keywords: Entomopathogenic fungus, hairy caterpillar, incubation period, colonization

Abstract

ABSTRACTEffect of gamma radiation and fusaric acid for resistance to wild Fusarium disease onabaca plant (Mum textillis Nee). The problem in abaca production is wilt disease infectioncaused by Fusarium oxysporzim. The resistant variety against the pathogen has not beenavailable yet. The disease resistance character of the species might be improved throughsomaclonal variation and in vitro selection. Different pure toxin of fusaric acid concentration(0, 15,30,45,60, and 75 mg/l) was used as component selection to get new hope numbers ofresistant abaca to wilt Fusarium disease through in vitro selection. Concentration of 45 mgllfusaric acid is lethal for abaca, so we used this concentration as dose of selection to selectshoots from irradiated calli. Gamma irradiation was used as mutagent to increase somaclonalvariation on abaca. Six levels of gamma-ray radiation (0, 0.5, 1, 2, and 3 Krad) were appliedto embriogenic calli. Increasing dose of radiation decreased the viability of calli. LDso wasfound between 1-1.5 Krad of radiation dose. In vitro selection was carried out in two stages.The concentration of selection of hsaric acid in stage I1 was increased one level to theconcentration in stage 1. Stage I selection of shoots from irradiated calli on mediumcontaining pure toxin 45 mg/l fusaric acid, showed that the survival capacity decreasing withthe increasing doses of gamma irradiation. In stage 11, shoots from irradiated calli (at 0.5 and1 Krad) could survive on medium containing 60 mg/l fusaric acid. In medium selectioncontaining 50% filtrate F. oxysporum, fusaric acid resistant shoots were also filtrate resistant.There was a correlation between in vitro fusaric acid and filtrate of F. oxysporum resistantplant and conidia suspension of F. oxysporum resistkt plant in the greenhouse.Keywords: Gamma radiation, in vitro selection, fusaric acid, Musa textilis, Fusariumoxysporum

Abstract

ABSTRAK: Pemetaan kerusakan terumbu karang akibat kandasnya kapal tongkang di P. Tengah dan di P. Cilik, Taman Nasional Karimunjawa, Jawa Tengah telah dilakukan 2-3 bulan setelah kejadian dengan cara mengukur luas area kerusakan dan menilai kondisi terumbu karang. Pengukuran area kerusakan menggunakan metode penginderaan jarak jauh berbasis Drone (UAV Drone/pesawat tanpa awak) dan penilaian kondisi ekosistem terumbu karang dengan menggunakan metode Underwater Photo Transect (UPT). Tujuan penelitian ini adalah untuk mengetahui kondisi dan kerusakan terumbu karang akibat kandasnya kapal tongkang di P. Cilik dan P. Tengah, Taman Nasional Karimunjawa. Hasil menunjukkan telah terjadi kerusakan fisik di lereng atas terumbu karang pada kedua pulau tersebut berupa karang mati dan pecahan karang. Luas kerusakan terumbu karang di P. Tengah (1.420,32 m2) lima kali lebih luas daripada luas kerusakan terumbu karang di P. Cilik (267,22 m2). Luasnya kerusakan terumbu karang di P. Tengah kemungkinan akibat perbedaan jumlah kapal tongkang yang kandas, waktu kandas dan dominasi karang yang mudah patah (fragile). Komunitas karang keras yang dominan di lereng terumbu P. Tengah adalah karang bercabang (CB), Acropora bercabang (ACB) dan karang lembaran/foliose (CF). Luasan kerusakan dan kondisi terumbu karang akibat kandasnya kapal tongkang ini dapat digunakan untuk pengelola kawasan konservasi dalam perencanaan perlindungan dan restorasi ekosistem terumbu karang di Taman Nasional Karimunjawa  ABSTRACT: Mapping damage to coral reefs due to the barges grounding in Cilik Island (P. Cilik) and Tengah Island (P. Tengah), Karimunjawa National Park, Central Java was carried out 2-3 months after the event by measuring the extent of damage and coral reefs assessment. Damage area measurement using Drone (UAV Drone) based remote sensing and reef ecosystem assessment using the Underwater Photo Transect (UPT) method. The aim of this study was to determine the condition and damage of coral reefs due to the wrecking of barges in Cilik and Central P., Karimunjawa National Park The results show that physical damage has occurred on the upper slopes of coral reefs on both islands is dead coral and coral fragments. Damage to extensive coral reefs in P. Tengah (1,420.32 m2) is five times larger than extensive damage to coral reefs in P. Cilik (267.22 m2). Damage to coral reefs in P. Tengah may cause differences in the number of barges that ran aground, time of aground and the dominance of fragile corals the upper slopes of the coral reefs. The dominant hard coral communities on the upper slopes of P. Tengah reefs are generally composed the fragile corals, such as branching corals (CB), branching Acropora (ACB) and foliose corals (CF). Damage to coral reefs and the condition of the ecosystem caused by the aground of the barges can be used to manage conservation areas in the planning of conservation and restoration of coral reef ecosystems in the Karimunjawa National Park in near future.

Abstract

The hydrogeological condition of a region is determined by the type of lithology, morphology, and subsurface conditions where the condition is very helpful in the study of groundwater exploration. Especially when we encounter interesting geological conditions when the groundwater exploration in the karst area in which volcanic rocks are resulting from the activities of the active volcano in the past. Groundwater exploration at Ponjong area and surrounding does have its special characteristics, because it has 2 different rock characteristics where the northern part of the research area in the form of a karst area (limestone of Wonosari Formation) while the southern part is an area of ancient volcanoes with dominant volcanic rocks from Wuni Formation, As for the research on the above and subsurface research area where the research is conducted based on surface geology mapping, geoelectric data collection, and groundwater sampling. Geological mapping includes geomorphological data, stratigraphy, and geological structure. The aquifer system of the research area can be divided into two systems, inter-grain aquifer systems, and fracture aquifer systems. Overall quality groundwater in the research area is quite good. Ponjong District there are mining activities that have resulted in changes in the land use system in the area. This can cause changes in the water surplus in the area due to the changing catchment area.

Abstract

Pepper yellow leaf curl virus (PepYLCV) infection transmitted by silverleaf whitefly (Bemisia tabaci [Gennadius]) can decrease chili pepper yield up to 100%. At this moment, there is no chili pepper variety resistant to PepYLCV available. Genome editing approach through CRISPR/Cas9 is an effort to develop variety resistance to the viral infection. The purpose of this study was to obtain M2 lines developed by CRISPR/Cas9 system on proliferating cell nuclear antigen (PCNA) gene for resistance to PepYLCV. A total of four M2 lines (C47-7, L84-2, L84-23, and L120-19) consisting of 60 chili plants were tested for their resistance to PepYLCV. PCR analysis was performed to detect the presence (infection) of the virus. The results showed that a total of 35 plants derived from the four lines were resistant to PepYLCV. They consisted of 7 plants from C47-7 line, 11 plants from L84-2 line, 9 plants from L84-23 line, and 8 plants from L120-19 line. PCR analysis confirmed that the resistant plants obtained from this study were negatively infected by the virus. Since not all tested plants were resistant to virus infection, the PCNA gene allele in these resistant lines were most likely heterozigotes. Sequencing of PCNA gene of the resistant lines is needed to confirm that the resistance phenotypes obtained was due to mutation of the gene. Therefore, further selection needs to be performed to obtain stable and PepYLCV-resistant lines.
