Abstract

This study examined the effect of climate change on agricultural output growth in Ethiopia. Co- Integration and Vector Error Correction Model estimation technique and data for the period 1981-2016 was used. Changing in annual mean temperature, annual mean rainfall, carbon dioxide emission and forest depletion were used to attribute variables for climate change. The result of vector error correction model indicate that both in the long-run and short-run, carbon dioxide emissions negatively affect agricultural output growth in Ethiopia. Annual temperature and annual rainfall negatively affect agricultural output growth in the long run and short run respectively.  On the other hand, forest depletion has positive effect on agricultural output growth both long run and the short-run respectively. Policy maker should develop policies to reduce sources of carbon dioxide emissions and introduce mitigation and adaptation measures to sustain the agricultural economic growth.

Abstract

Sampali Village is an agricultural area that is very suitable for banana planting. Various types of bananas found in the village include Barangan, Kepok, Molen, Raja and banana Nangka . Banana shoots from harvested mother plants are used for development in new areas. Banana seedlings from the suckers appear healthy, but often these suckers die after 1-2 months of planting in new areas. This is because these bananas have been infected with fungal pathogen wilt caused by Fusarium oxysporm f. sp cubense and Ralstonia syzygii subsp. celebesensis causes of blood diseases. Both of these pathogens are the main cause of the low quality of banana seeds. The use of low-quality banana seedlings (sapling sources), high pest and disease attacks are the factors causing the reduced amount of banana planting land which results in low banana production in Sampali Village, Percut Sei Tuan District, Deli Serdang Regency. Banana farmer groups in the village of Sampali have never used and planted banana seedlings that were propagated by tissue culture. The objectives of the activity were: 1. Socialization and practice of propagation of banana seedlings from sucker . Mycorrhizal inoculant application when planting seedlings in a polybag. To increase the knowledge of farmer group members and also the  students of Agricukture Faculty,Universitas Medan Area the learning of banana propagation techniques is carried out in vitro at the Balai Benih Induk Hortikultura, Gedung Johor Medan . The method used to solve the above problems is the provision of material, the practice of making banana seedlings through the propagation of tillers and a visit to the Balai Benih Induk Hortikultura, Gedung Johor Medan. At the end of the activity, an increase in the knowledge and skills of participants in providing quality banana seeds is the source of banana propagation in the village Sampali

Abstract

Indonesia is one of the most disaster-prone countries, often regarded as a “world disaster laboratory.” Natural disasters cause destruction and human suffering, especially in low- and middle-income countries Objective: This paper presents the overview of a medical emergency and public health response towards several recent earthquakes in Pidie Jaya, Lombok, and Palu of Indonesia. Case Series: The authors examine the appropriateness and effectiveness of the organized disaster response of the Pidie Jaya, Lombok, and Palu earthquakes in medical emergency response. Pidie Jaya Earthquake: A 6.4 magnitude earthquake struck off Pidie Jaya Regency, province of Aceh in Sumatra Island, Indonesia, resulting in 104 people died and others 395 injured. Lombok Earthquake: A series of moderate and strong earthquakes have rocked cities and regencies in Lombok Island, West Nusa Tenggara (NTB) causing 436 people died, 783 people with severe injury and 570 people with a mild injury. Palu Earthquake: The 7.7 magnitude earthquake hit Donggala district and also affected Palu city and Parigi Mountong regency causing 2657 people died, 4471 people with severe injury and 87,835 people with a mild injury. Important Findings: Though Indonesia has made outstanding progress in disaster management, the country still has many challenges and problems to overcome. The integration of data and information about health needs the progress of relief work, and about various other problems related to health is one of the most urgent and vital for better improving the medical emergency response and public health-related support in disaster settings.

Abstract

In essence, an explosion from LPG gas cylinders can be avoided if precautions are taken early, when gas leaks occur through cylinders, regulators, hoses or gas stoves. Along with the development of increasingly modern science and technology, a security system is developed by providing an Early Warning System. If this system detects a system leak, it will give a signal to the LCD or buzzer. A gas leak gives a signal to the sensor to work, MQ-6 and a 2360 microcontroller to work detecting a gas leak which is then read on the LCD screen, and in certain circumstances the buzzer will sound. And turn off the relay so that the inlet voltage to supply the solenoid gas valve is cut off, and the gas line is closed. The maximum distance that the gas sensor can detect in this paper is 18 cm, if the voltage on the sensor is greater than 2.33 volts, the LCD will give a signal of a gas leak and the buzzer will sound.

Abstract

In this article we transmute the logistic distribution using quadratic rank transmutation map to develop a transmuted logistic distribution. The quadratic rank transmutation map enables the introduction of extra parameter into its parent model to enhance more flexibility in the analysis of data in various disciplines such as biological sciences, actuarial science, finance and insurance. The mathematical properties such as moment generating function, quantile, median and characteristic function of this distribution are discussed. The probability density functions of the minimum and maximum order statistics of the transmuted logistic distribution are established and the relationships between the probability density functions of the minimum and maximum order statistics of the parent model and the probability density function of the transmuted logistic distribution are considered. The parameter estimation is done by the method of maximum likelihood estimation. The flexibility of the model in statistical data analysis and its applicability is demonstrated by using it to fit relevant data. The study is concluded by demonstrating that the transmuted logistic distribution performs better than its parent model.

Abstract

A laboratory study was conducted to investigate the efficacy of powder and extract of C. alata on Callosobruchus maculatus Fab. damage in stored cowpea (Vigna unguiculata L.) seeds. The powder and the extract were evaluated on C. maculatus for mortality, oviposition and adult emergence effects. The long-term storage of the treated seeds was also investigated. All treatments recorded higher significant (p < 0.05) mortality than the experimental control. Highest mortality of 100 % was recorded in seeds treated with C. alata extract at the dosage level of 4.0 % v/w while highest mortality of 80.30 % was also recorded in seed treated with 4.0 g of C. alata powder. The powder and the extract significantly reduced oviposition and adult emergence in the treated seed. Adult emergence was totally suppressed in seeds treated with 3.0 % v/w and 4.0 % v/w. The powder and the extract also reduced infestation and subsequence damage of the treated seeds. No damage was recorded in seeds treated with 3.0 % v/w and 4.0 % v/w of the extract. The result obtained revealed that extract and powder of C. alata were effective in controlling C. maculatus and could be recommended as an alternative to synthetic insecticides.

Abstract

In general, polymer composite materials are molded in solid form and avoid the occurrence of gas bubbles trapped in the matrix. The resulting material becomes rigid and does not have a good ability to absorb the load given. At this time, innovations in the field of composite materials have been carried out and produced polymer composite materials with foam-shaped structures that are able to reduce the load given. In this study, a composite foam material reinforced with PEBF fiber was tested with an impact dynamic load and the test results were numerically analyzed by the finite element method. The purpose of this study is to obtain the stress distribution at the fracture point due to the impact of dynamic loads at high strain rates with the finite element analysis method. Impact dynamic test using the Air Gun Compressor (AGC) test with an impact pressure of 0.2 – 0.8 MPa. Strain wave propagation in the test specimen was recorded using two strain gauges. Numerical analysis is carried out with the help of Msc. Nastran software. Experimentally, a failure in the specimen occurred at an impact pressure of 0.4 MPa and an impact distance (ID) of 500 mm. Strain wave propagation time in the specimen averaged 37.5 ms, at which time the tensile and compressive stresses intersected at a distance of about 120 to 155 mm from the starting point of loading. The magnitude of the stress distribution in the range of the fracture zone is between 800 to 900 MPa.

Abstract

The aims of the study is to find out pre – anesthesia assessment and preparation. The result of the study shows that Pre-anesthesia is an important first step in a series of anesthesia procedures performed on patients who are planned to undergo surgery. The things that need to be done include history taking, physical examination, laboratory examination, and physical status classification. Preparations are made at the clinic or at home for outpatients, in the treatment room, in the Central Surgery Installation (IBS) room, and in the operating room. Pre-anesthesia physical status assessment is very important. Anesthesia is not differentiated based on the size of the surgery but consideration of the choice of anesthesia techniques that will be given to patients is very complex and comprehensive considering all types of anesthesia have risk factors for complications that can threaten the patient's life

Abstract

Electrical energy has become a basic need for all people in the world, alternative energy as described above can be applied to households that are supplied by two energy sources namely energy sources from solar panels and PLN need to be accompanied by a system of regulating the supply of electric load power (control systems), so that the change of electrical energy supply to the load can work automatically. Along with the continued increase in the Basic Electricity Tariff (TDL) it is necessary to design a measurement of the use of electrical loads in households using the Pzem-004T Sensor to determine the amount of power from an electrical load and can be monitored from a certain distance. From the results of tests and measurements with various household loadings for 0 days, a very significant comparison from the previous TDL of Rp. 159,000.00, - and after using the Pzem-004T Sensor, the result of the TDL tariff calculation is Rp. 109,308.
