Abstract

Research on the vegetation diversity and bord habitat profi le has been carried outin the Mangrove Forest of Pulau Nyamuk in Karimunjawa National Park to examinethe relationship between vegetation types and mangrove habitat profi le and the spatialusage by birds. A transect method has been employed to survey the vegetation and thepoint count method was used to survey the birds. There were 14 vegetation types and 19species of birds from 14 families at two observational sites in mangrove forest in PulauNyamuk. Exchoecaria agallocha dominated the eastern part of Pulau Nyamuk, whereasLumnitzera racemosa dominated the northern part of the island. The vegetational spaceutilization by birds can be grouped based on the vertical vegetation stratifi cation, i.e. theland, the understorey, the subcanopy and the canopy.Keywords: mangrove vegetation, bird habitat, Pulau Nyamuk, Karimunjawa

Abstract

One of central goal in ecology is to understand how plants respond to environment and what kind of attributes that can be obtained with an easy way to interpret the complexity of nature, especially on vegetation response. Ecologists use functional traits to understand how plants respond to environmental changes. Plant species may have experienced different environmental conditions during their ontogeny. Thus, they may show different patterns of ontogenetic trait variation (OTV) as their response to different environmental condition. In this study, the relationship between trait variation on different habitat and across ontogenetic stages both on community and population levels were investigated. Five selected leaves traits (leaf area, specific leaf area, leaf thickness, leaf dry matter content, and leaf succulence) were examined to look at plant response along soil water content and light gap interception gradient in Kenting forest dynamics plot (KFDP), Southern Taiwan. Leaf area was the most varied trait across habitat and ontogeny. Leaf thickness reveals an opposite pattern compare to leaf area. Leaf dry matter content (LDMC) showed less variation either between or within species and across ontogeny. Shift of community responses on environmental gradient by trait through ontogeny showed that intraspecific variation is important to be considered in ecological study. The other important finding in this study was by only using mean species we can misleading in understanding of plant responses to the environmental gradient in order to their adaptation both across different habitat and ontogenetic stages.

Abstract

Mangifera indica L. var. wirasangka or wirasangka mango, a local plant in Tegal Regency, has a low population because it is rarely planted by people as its unknown nutritional content. To increase people's interest in planting, it is necessary to know the nutritional content of wirasangka mango. The aim of the study was to compare the nutritional content of wirasangka mango with three other varieties in Tegal Regency. This study used a one-factor completely randomized design. The factor was the mango variety which included six varieties, namely the varieties of wirasangka from three areas, okyong, tengkoeh, and golek. The variables observed were content of water, fiber, fructose, β-carotene, potassium and iron, as well as vitamin C and antioxidant activity. Normally distributed data were analyzed using One-Way Analysis of Variance and Least Significant Difference (LSD) test. Besides, the non-normally distribution data were analyzed using Kruskal Walis and continued with post-hoc test, i.e. Mann-Whitney. The results showed that the levels of water, dietary fiber, fructose, β-carotene, and iron were significantly different at the significance level of 0.1. Wirasangka mango has a higher fiber, and fructose content, but lower of β-carotene and iron content compared to okyong, tengkoeh and golek mangoes. The levels of vitamin C, potassium, and antioxidant activity of wirasangka mango were equivalent to the three other varieties studied. Thus the wirasangka mango has advantages which are expected to increase the interest of people in Tegal Regency to plant this variety. As a result, its population in the future will also increase.

Abstract

Bitcoin, as a form of cryptocurrency operating within a decentralized network known as blockchain, has become a global phenomenon with increasing value and popularity. Despite offering various opportunities, Bitcoin also raises numerous questions and controversies, particularly from the perspective of Islamic economics, which has specific principles and rules regarding asset ownership, investment, and financial transactions. This study aims to analyze the status of Bitcoin ownership as a digital asset from the viewpoint of Islamic economics. The research method employed is qualitative with a literature review approach. Data were obtained through relevant literature, including journals, books, articles, and fatwas from scholars. The results of the study indicate that the extreme price volatility of Bitcoin tends to trigger excessive speculation (maisir), which is prohibited in Islamic economics as it can lead to injustice and uncertainty (gharar) in transactions. Additionaly, Bitcoin is often associated with activities that do not align with Sharia principles, such as gambling and ilegal transactions

Abstract

The Ngalah Purwosari Islamic Boarding School is one of the Ngalah Islamic Boarding Schools that requires students to memorize nadhom nahwu science at the wustho level. The purpose of this study was to determine the effect of nadhoman retention on increasing achievement in learning the book of alfiyah ibn malik at the Ngalah Purwosari Islamic Boarding School, and to determine the relationship of nadhoman retention to increasing achievement in learning the book of alfiyah ibn malik at the Ngalah Purwosari Islamic Boarding School. This research uses quantitative research methods. This study used 45 respondents of wustho santriwati as research subjects. Based on the validity test and reliability test on the knowledge variable questions, 20 valid questions were obtained with a correlation value of more than 0.294. The validity test on the question list is declared valid because all have met the criteria. In the reliability test of the variables of knowledge, attitudes and behavior, realistic or consistent results were obtained because each of the reliability tests obtained a coefficient value of 0.724. An r value of 0.876 is given for the hypothesis testing phase based on correlation testing. It is in the range of 0.70 to 0.90, so we can say that it is related. This means that the degree of relationship between the two variables is very high, and since the significance test shows values of 0.00 < 0.05, it can be said that a hypothesis test with the label "There is a relationship between pre-test and post-test" is acceptable.
