Abstract

The proposition is an argument or statement which has a truth value. Propositional Logic is a branch of Mathematical Logic that focuses on propositions and relations between them. Semantic tree (also known as truth tree, semantic tableau, or tableaux) is a method to grow truth-value assignment on trees. In this research article, the semantic tree method is used to analyze propositions and relations between propositions such as validity, consistency, equivalence, and logical entailment of propositions.

Abstract

Let  be the set of nonzero divisors of the commutative ring . The zero divisor graph of  is  with the set of vertices , where two distinct vertices  and  are neighbors if and only if . The value of the upper dimension and the minimum solution set (base) of the zero divisor graph  is finite. The steps to find the upper dimensions and base are from the specified ring, determine the zero divisor graph of the ring, and look for a different representation of . The set  is called the solution set if all the vertices of  have different representations of . In this study, some theorem about upper dimensions and base of the zero divisor graph of the commutative ring are discussed.

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

Bacillus sp. are gram positive bacteria. Thesa bacteria are able to decompose complax compounds into simpler compounds, to reduce thze negative effects of chemical pesticides, it is necessary to develop alternative methods that are safer and environmentally friendly to control plant diseases. This macroscopic observation only looks at the colony and cannot tell whether these bacteria have an effect on plants. Bacillus sp. it includes a distinct physiological group of on-pathogenic bacteria, which are realitively easy to manipulate genetically and simple to cultuure, which strengthens their suitability for industrial purposes. Macroscopic observation of Bacillus sp. this gets the number of colonies ±20. Further observation are needed to find aot whether it is good for use for the community.

Abstract

The Zingiberaceae tribe is a plant that has the potential as a traditional medicine that is widely used by the community in curing various diseases. This study aims to determine the diversity and utilization of Zingiberaceae tribal plants as traditional medicine in Tiremenggal village. The method used in this study is a descriptive method with qualitative and quantitative approaches, to determine the analysis of the value of community use of medicinal plants analyzed by the ICS (Indexs of Cultural Significance) method. There are 5 families of Zingiberaceae which are used by the people of Tiremenggal village, namely ginger, turmeric, galangal, kencur and temulawak. The plant that is often used by the community as a treatment is ginger. The part that is used as medicine is the rhizome, which is mostly used to treat stomach pain, taken by mouth. Medicinal plants that are used by the community traditionally are still used today even though the preparation is done simply.

Abstract

Tea is the most widely consumed type of beverage that can be refreshing, has benefits for the body and can be enjoyed by brewing. Herbal tea ingredients can come from leaves that have a high antioxidant content and which are beneficial for the body, namely soursop leaves, lemongrass with variations of red ginger. Lemongrass and red ginger contain functional compounds that are beneficial for the body's immunity. Making tea begins with the process of finding materials, washing, drying, refining to the packaging process. The making of tea must be precise with sufficient drying process so that the color, aroma and taste are right when consumed. This herbal tea is sold at a price of Rp. 12,000.00 per box with 1 box containing 20 teabags. In conclusion, ginger can be used as an additional ingredient in the manufacture of functional drinks of soursop and lemongrass leaves.

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.

Abstract

Spodoptera litura F. is a plant pest organism (OPT) on shallot plants that must be prevented so that shallots become productive. One way to prevent it is good and not to damage the environment is the use of tumangsari plants in the form of celery plants. The purpose of the study was to determine the effectiveness of celery (Apium Graveolens L.) as a pest population of Spodoptera Litura F. Repellent Plants in the Cultivation of Shallots (Allium Ascalonicum L.) in Pesanggrahan Village. This research is an experimental study using a randomized block design (RAK) pattern, one way ANOVA test data analysis technique with 5% significance and post hoc follow-up test with the smallest difference analysis. The results showed that celery plants were effective in suppressing Spodoptera litura F. pest attacks. The most effective treatment was 4 PTS treatment which could reduce Spodoptera litura F. population and zinc intensity of Spodoptera litura F., which were 1.66 and 0, respectively. 15%.
