Abstract

Ni-doped MOF-5s were successfully synthesized by the solvothermal method for 12 hours at 140 °C. The mmol ratio of Ni/Zn was varied, i.e 0,05 and 0,1, to study the effect of Ni(II)-doped on the formation of MOF-5 materials. The Ni-MOF-5 materials were characterized using X-ray diffraction and scanning electron microscopy-energy dispersive X-ray (SEM-EDX). The XRD patterns and morphology of the Ni-MOF-5 were similar to that of synthesized MOF-5 and standard. The results of SEM-EDX showed that nickel was found in the Ni-MOF-5.

Abstract

Problem of linear equation, integral equation, and differential equation can be solved with a fixed point. One of generalization of metric space is b-metric space. This article discusses a lemma, a theorem and an example in b-metric space. We discuss a theorem about uniqueness and existence of fixed point.

Abstract

The used of refugia plants can be a solution in pest control by providing microhabitats for natural enemies. There are predators and parasitoids as alternative hosts. This study aimed to determine the diversity of insect pests in rice plantations using refugia and without refugia plants in Besur Village, Lamongan. This study used the rice variety Mentik Wangi Susu. The sampling method used 3 kinds of traps: sweep net, pit fall trap, and yellow sticky trap. The results showed that the insect pests found were 5 orders, 11 families, and 14 species with a total of 1272 individuals on refugia land and 1534 individuals on land without refugia. The Shanon-Weiner diversity index (H?) of insect pests on refugia land is H? = 1.93 and on land without refugia H? = 1.86 which is in the medium criteria.

Abstract

Abstract Dengue hemorrhagic fever (DHF) is a disease that is a problem in society. Lamongan Regency has been declared a DHF KLB (Extraordinary Event) with a number of 86 cases in 2015. The village with the highest incidence of DHF in Lamongan Regency is Payaman Village. This study aims to analyze the physical and chemical factors of the water used as a breeding ground for Aedes spp. This research is a descriptive study with a cross sectional approach. Sampling was carried out in 50 houses located in Payaman Village, Solokuro, Lamongan district. The research parameters there are volume of water, temperature, pH, value of water turbidity (NTU), and DO value. The results showed that each type of container has different physical and chemical properties of water. The highest volume of water is in the bathtub type with an average water volume of 152,500 ml. While the least was in the axillary types of Musa paradisiaca (185 ml) and Colocasia esculenta (177 ml). The average water temperature at the breeding site ranges from 25-30oC. The acidity of the water ranges from 6-7. The value of DO levels ranged from 5-8.5 ppm. The value of water turbidity ranges from 4.50-25 NTU with an average of 15.31 NTU. Keywords: physicochemical, breeding ste, Aedes spp., Payaman, Lamongan

Abstract

Utilization of fruit peel organic waste into bio-compost is one of the countermeasures of the harmful impacts on health or the environment. Therefore, the technique of making compost with the basic ingredients of organic waste is anaerobic and physical analysis of the composting results is carried out. This research was conducted in December 2021 – March 2022 at the traditional markets of Sekaran Village and Jangkungsumo Village. This research is classified as exploratory using purposive sampling technique. The results obtained are that in the composting process there are several stages including composting, fermentation and compost burial. On the physical characteristics that have been analyzed in compost made from organic waste, the fruit skin has a blackish color like soil, then has a dense and crumbly texture and smells of earth. This has met the compost standards that have been determined.

Abstract

Environmental problems are important to overcame. This is related to the resulting problem. Pollutants can make natural conditions unbalanced. One of environmental problems is presence of water used for washing clothes. Alternative water pollution reduction need conducted with acidic conditions. Acidic conditions can be play a role as cleaner so conducted research with peels orange fermented. The aim of research is fin out character peels orange fermented as reducer clothes washing contamination. The research carry out to conducted character peels orange fermented as reducer clothes washing contamination. The research methods are descriptive qualitative and quantitative. This type of experimental research is used in this study. The result showed that character peels orange fermented was sour smell from peels orange dominant and brown orange color. The result of fermentation was pH (3.20) and temperature 30.2 ?C at T40. Pollutants clothes washing contamination test with peels orange fermented at T5 for pH and temperature respectively 4.14 and 33.5 ?C.

Abstract

The purpose of writing this article is to explain how al-Khwarizmi's theory of algebra. Al-Khwarizmi's algebraic theory introduces a geometrical algebraic approach. In the book fi al-jabr wa al-muqabala, al-Khwarizmi gives an initial definition of squares, roots, and numbers. Al-Khwarizmi made three main principles of algebra through this definition. One of the principles discussed in this article is that the square plus the root equals the number (x2 +bx = c).
