Opis:: Plastic is a source of pollution both on land and sea that can disrupt balance of the ecosystem. The characteristic of plastic as a material is difficult to decompose causing problems for environment. Various research needed to produce bioplastics that easily biodegradable in about 60 days. Biodegradable plastics are made from organic materials in the form of starch. Durian seed starch is one of the potential raw materials that can be used as bioplastics. Durian fruit is one of the typical fruits in Indonesia, at present seeds of durian had not been used as raw materials to produce object with economic values. It is necessary to combine the processing of durian seeds through a recovery approach in the form of processing into bioplastics. The aim of study is to analyze the effect of adding PEG 400 as a plasticizer plus calcium carbonate as a solidifier. Tests were carried out on swelling ability, acid and base resistance, tensile strength and biodegradation. The variation of the addition of PEG 400 is 4%; 30%; 50% and 70% were carried out to analyze the effect of different concentrations of plasticizers. None of the tensile test results met SNI 7188-11:2018 but all variations had biodegradation values according to SNI 7188-11:2018. Swelling test resulted from 4% and 30% are 1.2% and 2.1% respectively.

Opis:: Biofilters, commonly called rain gardens, are becoming increasingly popular among best-management practices (BMPs). They have recently sparked significant interest due to their ability to control stormwater quality. These systems face challenges in manipulating dissolved nitrogen and phosphorus species. This study reports the results of the removal of nitrogen and phosphorus in two modified bioretention systems. The performance of modified bioretention with coconut and durian was compared. The modified bioretention system was evaluated as a single and a series. Sequencing these systems in a series maintained the continuity of nutrient removal. Both series efficiently removed NH3-N (97% in TC5, 95% in TD5), while the removal of NO3-N was moderate (65% inTC5, 67% in TD5). Good removal efficiencies of TP were observed in two series (84% in TC5, 81% in TD5). However, the PO4 removal was equalized in all series (98%). The TN and ON removal were poor and fluctuated with time and column number in TC5, the overall removal efficiencies were (69% and 43%), respectively, while in TD5 a significant fraction of TN and ON were removed (86% and 78%), respectively. As compared with coconut husk, durian peel is considered a promising material that can enhance the water quality in bioretention systems.

Opis:: The effect of different ripening stages of durian Durio zibethinus fruit on zinc content in liver of rats loaded with cholesterol. Durian Durio zibethinus is an exotic, climacteric fruit, rich in dietary fiber, polyphenols, saccharides, vitamins and minerals. Postharvest changes in durian fruit influence its physical and chemical quality, which determined its health protective effect – antioxidant and hypocholesterolemic. Durian is a good source of zinc. The aim of this study was to investigate the zinc content in lyophilisate of durian fruit and in the diets supplemented with durian fruits at different stages of maturity. The in vivo experiment was designed to determine the influence of these diets on zinc content in the liver of rats loaded with cholesterol. The zinc content in durian fruit, in the diets, and in rats livers was examined using a flame atomic absorption spectrophotometry (Perkin-Elemer 1100B). The zinc content in durian fruits ranged from 8.1 to 12.3 mg/kg. The zinc content amounted 45.0, 44.2, 47.1, 47.3 and 48.0 mg/kg in C, ch, chDM, ch DR and chDOR diet, respectively. The content of zinc in the liver in all animal groups was within the normal limits and amounted from 25.0 to 33.0 mg/kg fresh weight. Diet supplemented with durian fruits at different stages of ripening increases accumulation of zinc in the liver of rats loaded with cholesterol. Durian fruits, especially ripe ones, could be used as a natural supplementation of zinc in the diet and might be helpful in prevention of diseases or disorders related to zinc deficiency.
Wpływ różnych faz dojrzałości owocu durianu Durio zibethinus na zawartość cynku w wątrobie szczurów obciążonych cholesterolem. Durian Durio zibethinus to egzotyczny, klimakteryczny owoc, bogaty we włókno pokarmowe, polifenole, oligosacharydy, witaminy i minerały. Zmiany następujące po zbiorze owoców durianu wpływają na ich fizyczne i chemiczne parametry determinujące ich właściwości zdrowotne – przeciwutleniające i hypocholesterolemiczne. Durian jest cennym źródłem cynku. Celem badania było określenie zawartości cynku w owocach durianu, w dietach z dodatkiem durianu w różnych fazach jego dojrzałości. Badanie in vivo miało na celu określenie wpływu tych diet na zawartość cynku w wątrobie szczurów obciążonych cholesterolem. Zawartość cynku w owocach durianu, w dietach i wątrobach oznaczono metodą płomieniowej absorpcji atomowej (Perkin-Elmer 1100B). Zawartość cynku w liofilizacie owoców durianu mieściła się w zakresie 8,1–12,3 mg/kg. Zawartość cynku w dietach: C, ch, chDM, ch DR and chDOR wynosiła odpowiednio 45,0, 44,2, 47,1, 47,3 i 48,0 mg/kg. W wątrobie szczurów wszystkich grup zawartość cynku mieściła się w zakresie wartości referencyjnych i wynosiła od 25,0 do 33,0 mg/kg świeżej masy. Diety z dodatkiem owoców durianu w różnej fazie dojrzałości zwiększają akumulację cynku w wątrobie szczurów obciążonych cholesterolem. Owoce durianu, w szczególności dojrzałe, mogą być stosowane jako naturalny suplement cynku w diecie i być pomocne w prewencji chorób lub stanach związanych z niedoborem cynku.

Opis:: The molecular analysis of 32 durian F1 hybrids, resulted from crossing of the Arp 8990 (female parent) and ‘Otong’ (male parent), was conducted in order to determine the genetic characteristics of hybrids and parents, as it would be followed/evidenced by the variability of traits produced from the cross breeding. The RAPD analyses of 14 primers resulted in 114 scoring bands, 112 (98.2%) of them were polymorphic, with 4 to 11 bands amplified per primer. The electrophoresis gel of the PCR results revealed that some hybrids produced different band patterns compared to the parents; this indicated the crossing between parents’ alleles and trait combinations from both the parents. The Dice-Sorensen similarity coefficient demonstrated that most of the hybrids had distant genetic similarities with both parents, which were ranged from 0.141 [71B(4) and 72B(15)] to 0.776 [71B(15) and 48B(1)]. The UPGMA method was used to construct the dendrogram, which grouped the hybrids in five clusters with distinct genetic relationships and was confirmed with the PCA analysis. This result implied that above crossing produced hybrids having characters different from the parents.
