PENINGKATAN KEKUATAN TANAH ORGANIK DENGAN PENCAMPURAN EMPAT JENIS LIMBAH RAMAH LINGKUNGAN

Waste is one of the problems in Indonesia. Based on the Ministry of the Environment, each person produces an average of 0.8 kg of waste per day. The average waste per person will increase in line with the increase in people's welfare and lifestyle. Assuming 220 million Indonesians, waste reaches 176,000 tons per day. Accompanied by increasing population growth, the need for infrastructure development on land is increasing. Soils that is often used for construction land is organic soil. It has low soil bearing capacity values and soil improvement methods are commonly used. The general method usually is to mix the soil with better bearing capacity. To minimize costs, a physical stabilization system is carried out that can use soil improvement methods with waste. This can deal with 2 problems at once, where there is the use of certain types of waste and also the planning of organic soil stabilization with small carrying capacity. By doing a triaxial test on organic soil by mixing 4 different types of waste, it shows that the best waste mixture that can affect the bearing capacity of the soil in sequence is coconut husk, tile fragments, construction demolition debris, and chicken egg shells. ABSTRAKLimbah merupakan salah satu permasalahan di Indonesia, Berdasarkan informasi Kementerian lingkungan Hidup, setiap orang menghasilkan rata-rata 0,8 kg sampah per hari. Rata-rata limbah per orang akan meningkat sejalan dengan meningkatnya kesejahteraan dan gaya hidup masyarakat. Dengan asumsi 220 juta penduduk Indonesia, limbah mencapai 176.000 ton per hari. Diiringi dengan peningkatan pertumbuhan penduduk, maka kebutuhan pembangunan infrastruktur di lahan tanah semakin bertambah. Salah satu tanah yang sering dipakai untuk lahan konstruksi adalah tanah organik. Tanah organik memiliki nilai daya dukung tanah yang rendah dan biasa dilakukan metode perbaikan tanah. Metode umum yang biasa dilakukan adalah dengan melakukan pencampuran tanah dengan daya dukung yang lebih baik. Untuk memperkecil biaya maka dilakukannya sistem stabilisasi fisik yang bisa menggunakan metode perbaikan tanah dengan limbah. Hal ini bisa menangani 2 masalah sekaligus, dimana adanya pemanfaatan dari jenis limbah tertentu dan juga perencanaan stabilisasi tanah organik dengan daya dukung kecil. Dengan melakukin uji triaksial pada tanah organik dengan mencampurkan 4 jenis limbah berbeda menunjukan bahwa campuran limbah terbaik yang bisa mempengaruhi daya dukung tanah secara berurutan adalah sabut kelapa, pecahan genteng, puing pembongkaran konstruksi, dan cangkang telur ayam.

Method for preserving the viability of a chicken embryo with a shell defect in experiment

The egg has always been and remains an ideal object for conducting various scientific research. An egg is an isolated egg cell outside the mother’s body. Therefore, it is an ideal object for studying embryogenesis and performing various manipulations during embryogenesis and before the birth of a viable organism. The existing methods allow conducting experimental manipulations with the embryo in situ, inside the egg shells without damaging them. However, the achievement of ideal parameters for closing the defect of the fertilized egg shell in the experiment is the key to the successful completion of the experiment. Periods of embryogenesis, especially at the last stage, when osteogenesis occurs, require the presence of a sufficient amount of calcium ions in the metabolism of the developing chicken, which are vital for the formation of a full-fledged chicken.The aim: to develop an optimal method for closing the defect and fixing the egg shell after manipulation or during the experiment.Materials and methods. The experiment was carried out on fertile eggs of the breed of chickens – meat breed of broilers Ross-308 (ROSS-308), JSC Poultry Farm “NovoBaryshevskaya” (Koltsovo, Novosibirsk Region, Russian Federation). In the experiment, 120 fertilized eggs were used. Eggs weighing 60–70 g were incubated at a temperature of 37.5–38.0 °C and 50–55 % humidity. Comparative anatomical and physiological parameters were evaluated on the 7th, 14th, 20th day of incubation and on the 1st day of the postnatal period. In the experimental group, the shell defect was covered with a fragment of the egg shell of the donor. Incubation was carried out in an incubator – a household incubator “Nesushka” (Novosibirsk, Russian Federation).Results. The proposed method of fixing and closing the defect of the fertilized egg shell excludes the use of foreign materials that have an adverse effect on the development of the embryo. There were no anatomical and physiological deviations in the chicks of the study group when comparing the indicators with the parameters in the comparison group and the Hamburger – Hamilton classification.

The result showed that eggs producktion, eggs weight, feed cosumtion and feed convertion non significant effect (P>0.05), but was significant effect (P<0.05) on weight and thick of eggs shell It was concluded that giving egg shells to a level of 7.5% in the feed had enough potential to increase egg production and quality of laying hens with relatively good feed efficiency.

Ovicidal activity of spirotetramat and its effect on hatching, development and formation of Frankliniella occidentalis egg

Frankliniella occidentalis (Pergande) has become an important vegetable pest worldwide because of its economic damage to crop production. However, it is difficult to control due to its unique living habits. In this study, the eggs of F. occidentalis were used as the target to explore the ovicidal activity of spirotetramat on the thrips and its effect on hatching, development and formation. After the treatment of spirotetramat, the LC50 value descreased with increased egg age using egg dipping method, and showed the same trend as the leaf dipping method verified on living plants. Through ultra-depth-of-field microscopy, scanning electron microscopy and transmission electron microscopy, the egg shell and internal structures of F. occidentalis eggs were studied. Spirotetramat can destroy the egg shells of F. occidentalis, resulting in shrinkage of the egg surface, sunken pores, egg deformities, egg shell rupture and other phenomena. This allows spirotetramat to enter the egg and destroy the egg structure, making the egg internal structure flocculent, fuzzy and unevenly distributed, which affects embryonic development and causes the nymphs to die before hatching. Therefore, the prevention and control of F. occidentalis using spirotetramat before damage is caused to crops should have a better effect.

SPECIFIC FEATURES OF EMBRYONIC DEVELOPMENT OF POND SNAIL (LYMNAEA STAGNALIS L.) UNDER ANTHROPOGENIC INFLUENCE OF CHLORIDE COMPOUNDS IN WATER

The article highlights the research of embryonic development of hydrobionts under the influence of anthropogenic factors of water solutions – chlorobenzene and tetrachloroethylene. To detect the toxicity of chloride pollutants in a freshwater reservoir, representatives of benthic mollusks (big pond snail Lymnaea stagnalis L.) were used as a model organism. According to the results of research, it was found that at a concentration of 0.01 mg/l of chlorobenzene solution individual anomalies of embryonic development of the pond fish are observed, but at higher concentrations its development is delayed by 5-6 stages in comparison with the control. As an integral parameter of pond fish development, we can take indicators of the biological toxicity criterion: Hatchling and its survival over a 10-day period after leaving the egg shells. Changes in the physiological parameters of pond fish embryos begin with a chlorobenzene concentration of 0.01 mg/l; the maximum permissible concentration for tetrachloroethylene for the considered biological indicators should be considered 0.05 mg/l. It is noted that in big pond snail (Lymnaea stagnalis L.) the hatch of juveniles from egg shells is the most sensitive indicator when determining the toxicity of an aqueous solution; and less sensitive indicators are the number of eggs laid and the survival of juveniles in the first 10 days after hatching. The test object used is a large pond, which has shown a high sensitivity to contamination of the water environment with chlorinated ecotoxicants and can be recommended for a comprehensive quality assessment when biotesting freshwater waters

Nano-Hydroxyapatite vs. Xenografts: Synthesis, Characterization, and In Vitro Behavior

This research focused on the synthesis of apatite, starting from a natural biogenic calcium source (egg-shells) and its chemical and morpho-structural characterization in comparison with two commercial xenografts used as a bone substitute in dentistry. The synthesis route for the hydroxyapatite powder was the microwave-assisted hydrothermal technique, starting from annealed egg-shells as the precursor for lime and di-base ammonium phosphate as the phosphate precursor. The powders were characterized by Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDAX), transmission electron microscopy (TEM), X-ray fluorescence spectroscopy (XRF), and cytotoxicity assay in contact with amniotic fluid stem cell (AFSC) cultures. Compositional and structural similarities or differences between the powder synthesized from egg-shells (HA1) and the two commercial xenograft powders—Bio-Oss®, totally deproteinized cortical bovine bone, and Gen-Os®, partially deproteinized porcine bone—were revealed. The HA1 specimen presented a single mineral phase as polycrystalline apatite with a high crystallinity (Xc 0.92), a crystallite size of 43.73 nm, preferential growth under the c axes (002) direction, where it mineralizes in bone, a nano-rod particle morphology, and average lengths up to 77.29 nm and diameters up to 21.74 nm. The surface of the HA1 nanoparticles and internal mesopores (mean size of 3.3 ± 1.6 nm), acquired from high-pressure hydrothermal maturation, along with the precursor’s nature, could be responsible for the improved biocompatibility, biomolecule adhesion, and osteoconductive abilities in bone substitute applications. The cytotoxicity assay showed a better AFSC cell viability for HA1 powder than the commercial xenografts did, similar oxidative stress to the control sample, and improved results compared with Gen-Os. The presented preliminary biocompatibility results are promising for bone tissue regeneration applications of HA1, and the study will continue with further tests on osteoblast differentiation and mineralization.
