Radiation Synthesis of Adsorbents for Phosphate Removal from Aqueous Systems
Authors: Kavakli Pinar Akkash , Guven Olgun 
Published: March 2024

Nonwoven fabrics made of PE coated PP fibres were irradiated by accelerated electrons in inert atmospheres for grafting of two different monomers, glycidyl methacrylate and dimethylaminoethyl methacrylate. Grafting conditions were optimized by a systematic investigation of the effects of absorbed dose, monomer concentration, reaction temperature and duration. 150% grafted copolymers were later modifed by protonation and quaternization of poly(dimethylaminoethyl methacrylate) chains and by Cu(II) loading of dipyridyl amine modified poly(glycidyl methacrylate) graft chains. The PE/PP based adsorbents thus prepared were used for their suitability of removing phosphate ions from aqueous systems. Adsorption/ removal studies were carried out in both batch and continuous flow type systems. The selevtivity of adsorption of phosphate ions in the presence of other competing anions were also checked showing the enhanced selectivity for phosphate ions.

Bromelain fiber is the product of extracting the enzyme bromelain from pineapple hulls or peels. Bromelain fiber contains lignocellulose, which, when fully decomposed, is very beneficial for the environment, but it is quite challenging to degrade naturally. Hence, it requires a decomposer agent. The decomposer agents used in this study were cellulolytic fungi Aspergillus sp. (Bioggp 3) and ligninolytic Trichoderma sp. (Bioggp 2). This study aims to determine the effect of compost tea (CT) bromelain fiber induced by these fungi and obtain the best dose of the CT on the growth of land kale (Ipomoea reptans Poir.). This research was conducted in April–July 2022 at the Microbiology Laboratory of FMIPA Unila. This study used a completely randomized design (CRD) with 7 treatments and 4 replications, namely P0 (control), P1 (ACT 25%), P2 (NACT 25%), P3 (ACT 50%), P4 (NACT 50%), P5 (ACT 75%), P5 (NACT 75%). The parameters measured were plant height and number of leaves. The data were analyzed using ANOVA α = 5% followed by the Least Significant Difference (LSD) test with a 5% confidence interval. This study showed that the results with the highest height value and number of leaves were found in P3 (ACT 50%) while the lowest was in P0 (water control). It can be concluded that the ACT and NACT significantly affect the height and number of leaves, and the best dose was found in ACT 50% starting from day 10, 15 , 20, and 25 after planting.

Published: March 2024

Entomopathogenic nematodes (EPN) are potential nematodes as biological agents because they actively search for insect pests and are parasitic on their hosts. Two genera of EPN can be used as biological agents: Steinernema and Heterohabditis. It is necessary to explore local EPN on land suspected of having potential as a habitat for the nematodes. This study aimed to determine the genus and population of the EPN from corn and rice farms in Jember by identifying and characterizing them. The method used was the descriptive method. The EPN population was analyzed using the T-test. The results showed that the EPN from the corn and rice fields belonged to the Steinernema genus. EPN from the corn field isolate was characterized by a body length of 826,77 μm, body width of 47.14 μm, and tail length of 73.16 μm, while from the rice field, the isolate was characterized by a body length of 840.54 μm, body width of 37.70 μm, tail length 57.52 μm. EPN populations in maize and rice fields were not significantly different.

This research analyzes consumer behavior and its impact on the purchase decisions of ornamental plants at Taman Anggrek Ragunan, South Jakarta. The Taman Anggrek Ragunan is the largest ornamental center in Jakarta. During the COVID-19 pandemic, demand for ornamental plants at Taman Anggrek Ragunan decreased by 50%. This research aims to determine the characteristics of ornamental plant consumers and analyze consumer behavior and its impact on purchase decisions of ornamental plants at Taman Anggrek Ragunan, South Jakarta. Respondents in this research were ornamental plant consumers who made purchases at Taman Anggrek Ragunan and were selected using a non-purposive sampling technique. The data used in this research comprises primary data and secondary data. For qualitative data, we convert it using a Likert scale to be analyzed quantitatively. The data analysis method uses multiple linear regressions. The results of the research show that the factors that have a significant impact on the decision to purchase ornamental plants at Taman Anggrek Ragunan, South Jakarta, are personal factors and psychological factors, while social factors and cultural factors do not have a significant impact. Personal and cultural factors have more influence on purchasing decisions for male respondents than female respondents. The four variables influence respondents with a high school education level more than undergraduates. Meanwhile, based on income level, the influence of the variable is stronger for respondents with an IDR 4 million or less income.

Published: March 2024

Probiotics are microorganisms that are non-pathogenic and beneficial for health when used in certain doses through the mechanism of increasing the function of the small intestine in chickens. This study aims to analyze the effect of adding the probiotic Lactobacillus plantarum IIA-1A5 to feed to improve the body's immune system, production performance, and egg quality in laying hens aged 49‒52 weeks. The experimental design used was a Completely Randomized Design (CRD). The treatment for adding the probiotic Lactobacillus plantarum IIA-1A5 to feed consists of four treatment levels, namely P0 (without probiotics), P1 (feed + 8.1 x 106 cfu/g or 1 g/kg feed), P2 (feed + 2.43 x 107 cfu/g or 3 g/kg feed), and P3 (feed + 4.86 x 107 cfu/g or 6 g/kg feed). The results of the study showed that administering the probiotic Lactobacillus plantarum IIA-1A5 in feed could reduce Escherichia coli bacteria in the small intestine of laying hens. Giving the probiotic Lactobacillus plantarum also had a significant effect (P<0.05) on feed consumption and egg yolk color. The addition of the probiotic Lactobacillus plantarum IIA-1A5 in feed can increase animal resistance, performance, and quality of chicken eggs. The use of probiotics with a treatment level of 1 g kg-1 feed (8.1 x 106 cfu g-1) showed the best results.

Authors: Firmansyah Muhammad Alam , Wardhani Diah Ayu Pramudha 
Published: March 2024

Sengon (Paraserianthes falcataria (L.) Nielsen) is a fast-growing tree species, and its wood is readily available because it has been widely cultivated in Indonesia. Efforts to propagate sengon plants are carried out through breeding activities in the nursery. The study aimed to identify the fungus that causes leaf disease on sengon plants and calculate the extent and intensity of attacks by the fungus that causes leaf disease on sengon in the Dramaga Bogor Permanent Nursery. This research consisted of pathogenicity test activities, including field observations, Koch's postulates, and the identification of fungal species. The study used a Completely Randomized Factorial Design. The disease symptoms found around 2 months of sengon leaves at the observation site were leaf fall, leaf spot, and leaf blight. The identified fungus that caused leaf fall was Rhizoctonia sp. The fungus that caused leaf spots was Colletotrichum sp., and the fungus that caused leaf blight was Fusarium sp. Fusarium sp. resulted in the highest percentage of attacks, with a disease incidence of 67% and a disease severity of 57%.

Scale lice have attacked apple fields in 8 villages in Bumiaji District, Batu City, namely Giripurno, Tulungrejo, Pandanrejo, Sumbergondo, Bulukerto, Punten, Gunungsari, and Bumiaji villages since 2005. Knowledge of the biological aspects of this pest can be done using sticky bands. This is aimed at controlling pests. Determination of sample plants was carried out systematically as many as 18 sample plants on manalagi apple (Malus sylvestris). The sample plants were apple plants that were attacked by scale lice. The type of adhesive treatment was adjusted to the variation of position (east, west, central) and research height (1m and 1.5m). The results obtained were that the pest found was Diaspidiotus perniciosus and the natural enemy found was Encarsia strenua. The part that has the most attacks is the stem/twig. The eastern branch with a height of 1.5 m has a higher even distribution of scale lice than the other parts. The highest dominance index (C) of scale lice of 0.29 was obtained by the middle-adhesive treatment of height 1m or rootstock. The pattern of population distribution based on sticky bands is random and tends to be individualistic.

Published: March 2024

The two most extensively beekeeping honeybee species were Apis mellifera and A. cerana. Other species that produced honey, albeit with infrequent cultivation, include A. dorsata, A. florea, and some stingless bees, including Trigona and Melipona. Different types of honeybees were known to affect the quality of honey. Hence, this investigation aimed to conduct a meta-analysis to examine the similarities in honey quality between honey sourced from beekeeping and wild honeybees. Data analysis was performed using the OpenMEE software, facilitating the calculation of effect size and standard error. The effect size and common error data were subsequently organized into separate columns within a CSV file. This CSV file was then imported into the JASP 0.16.2 software to conduct heterogeneity and Egger tests to detect potential publication bias. The findings indicated significant disparities in the quality of honey produced by beekeeping, wild, and stingless bee honey, as determined by various parameters, including pH value, moisture, total sugar, acidity, HMF (hydroxymethylfurfural), and diastase enzyme levels (p < 0.05). According to the results of the meta-analysis, honey from beekeeping exhibited superior quality to that of wild and stingless bees. However, the average values of all parameters still adhered to the established honey quality standards set by the Standar Nasional Indonesia and the International Honey Standard (IHS).

This study identified the problem of landslide disasters that often occur in Sukorejo Village, Gunungpati District, Semarang City. Sukorejo village belongs to the high ground movement zone which has a high degree of vulnerability to soil movement. The purpose of the study was to determine efforts to increase the capacity of the community in facing landslide disasters through the preparation of evacuation standard operating procedures (SOPs). The data collection of this study used interview, observation, documentation, and geographic information systems (GIS) methods. Data analysis is carried out with the approach of spatial analysis and qualitative descriptive analysis. The results showed that the preparation of evacuation SOPs is very important to increase the capacity of the community during landslide emergency response. The recommendations given are the need to add an Early Warning System (EWS) tool, install evacuation route signs, and gathering points in landslide-prone areas. In addition, the community also needs to increase awareness and preparedness in the face of possible landslides. This research contributes to improving understanding of landslide disaster mitigation efforts and can be followed up by assessing community capacity and evaluating future evacuation SOPs.

Published: March 2024

The sex-chromatin test and the chromosome analysis are reviewed briefly in relation to the sexual development in normal and known abnormal conditions. Two cases of true hermaphroditism are reported. Chromosome analysis showed normal feminine constitution in both. Microscopical investigation of the ovotestis removed from case I showed the ovarian stroma without follicles with changes completely as in Turner's syndrome. The testicular elements had features in common with Klinefelter's syndrome. The tubules were completely hyalinized containing Sertoli cells only. Spermatogenic elements were not observed. The Leydig cells were numerous and often found in small adenomas. Case II was reported by Zachariae in 1955.

Rats and mice are the only wild mammals to be found in the Faroe Islands. The latter are presumably brought to the country by the Irish hermits. Mice are not to be found on all the islands and the damage caused by them is not so extensive as to require special legislation.
The black rat has presumably come to the Faroe Islands in the Middle Ages, as an epidemic like the Black Death could hardly develop without the presence of rats. There is some indication that the rats — apart from Tórshavn — have disappeared from the islands after the Black Death, and that only towards the middle of the 17th century they have gained ground again.
It is supposed that the brown rat came to the Faroe Islands in 1768. Ii soon spread over most of the islands and crowded out the black rat. It caused serious damage at the beginning, but it looks as if the damage has been less in the 19th century. In 1895 and 1902 there are grannastevnur (meetings of the landowners of a village) which deal with matters concerning rat extermination. In 1907/08 the question of the coming into force of the Danish Rats and Mice Destruction Act of March 22, 1907, is submitted to the Løgting (the Faroese Parliament), the members of which take no interest in it. The subsequent Danish Ratsand Mice Destruction Act of April 18, 1910, is put into force by promulgation without having been submitted to the Løgting, but it becomes of no importance. On the other hand, in 1915/16 the Løgting deals with a matter concerning the rat nuisance but leaves extermination to private enterprise, and from 1916/17 there are a couple of regulations adopted at grannastevnur concerning rat extermination. The Danish Rats and Mice Destruction Act of March 29, 1924 is put into force in the Faroe Islands without submission to the Løgting, but as was the case with the Act of 1910, it acquires no importance. It has hardly beenrealized that it was in force in the country, which, among other things, appears from the discussion of the Løgting in 1937/38 on the organization of rat extermination in the Faroe Islands. In the last part of the paper the author goes through the Løgting Act of June 1, 1961, governing rat extermination and the annexed circular of May 16, 1962.

Cystostomía suprapubica til at tøma landbløðruna gjøgnum samanborin við catheter á demeure aftan á vaginala skurðviðgerð
Authors: Simonsen Marner 
Published: March 2024

A prospective, comparative study in 73 patients was carried out to determine the value of trocar suprapubic cystostomy as a means of postoperative bladder drainage versus bladder drainage by transurethral catheter. The investigation was performed with 32 patients in the group with suprapubic cystostomy and 41 patients in the group with transurethral catheter.
The study showed a less incidence of urinary infection in the group with suprapubic cystostomy, finding urinary infection in 9 patients in this group (33°/o per cent) and 16 in the group with transurethral catheter (46 per cent).
On he other hand it is clearly showed that the mean days of urinary drainage and the mean days of postoperative hospitalization are equal in the two groups, so the adveantages of using suprapubic cystostomy are few.

This article challenges the traditional assumptions about one of the famous villains of Faroese history, Charles Baron Hompesch, who paid a visit to Tórshavn in his capacity as a privateer in the summer of 1808, sailing under British letters of marque, and removed both the public money chests and the stores in the warehouses of the Royal Danish Monopoly. The Faroese view of Baron Hompesch has usually been that he was a cruel plunderer, indifferent to the suffering he caused, butintent only on enriching himself at the cost of a defenceless people. The author first shows that this opinion was held in England, too, in Hompesch's time; but he goes on to demonstrate that the view arises from an account of the affair by the Danish commandant of the Tórshavn fort, Emilius Lobner, which can be shown in part to be false and one-sided. The money and goods were eventually returned to the Faroe Islands, the Prize Court having refused to award them to Hompesch. Thejudgement did not, however, arise from any misconduct of Baron Hompesch in Faroe, but from a prior claim of the British Crown, based on the capitulation signed by Løbner when the Clio, a British naval brig, disarmed the Tórshavn fort two weeks before Hompesch's visit.

Lucas Debes og Torfæus

In two of his works Torfæus refers to information given by Lucas Debes that the Færoese claimed to have been descended from a Scottish king, whom Torfæus identifies with Porsteinn rauðr, son of Auðr djúpúðga. The Færoese tradition mentioned by Lucas Debes may have arisen from a knowledge, in earlier times, of Laxdcela saga, which must have been known in the Fseroes, since an episode in it is the source of a Færoese ballad, 'Kjartans tættir'.
In the nineteenth and twentieth centuries was recorded a legend about a Scottish princess who is said to have come to the Færoes and acquired descendants there, but there can be no certainty that there is any connexion between this tradition and the old one.
