Characterization and Chemical Composition Analysis of Tea Tree (Meleuca alternifolia) Leaf Hydrosols Growing on Lombok Island

Tea tree is an essential oil-producing plant from Australia which is also found growing in several parts of Indonesia, including the island of Lombok. So far, tea tree essential oil producers on the island of Lombok do not utilize by-products in the form of hydrosol (distilled water) produced in the process of making essential oils. In this study, the characterization and analysis of the chemical composition of the hydrosol of tea tree leaves growing on the island of Lombok was carried out. The characteristic aroma of hydrosol is similar to that of tea tree essential oil. The results of the GC-MS analysis also showed that the hydrosol of tea tree leaves also had similarities with the essential oil, composed of major compounds in the form of trans-caryophyllene (28.58%), limonene (13.98%) and terpinen-4-ol (16.27%). Other compounds detected were -pinene (4.14%), -pinene (6.50%), -myrcene (8.09%), -terpineol (10.10%) and -terpinene (5.77%).

ANALISIS KETERKAITAN ANTARA KEKERINGAN METEOROLOGIS DENGAN INDEKS VEGETASI TERSTANDARISASI DI PULAU LOMBOK

Intisari Kekeringan merupakan bencana kompleks yang dapat menyebabkan kerugian masyarakat di berbagai sektor. Salah satu wilayah yang berisiko tinggi mengalami kekeringan adalah Pulau Lombok. Wilayah ini memiliki lahan yang berisiko terkena kekeringan seluas 405.985 ha. Tingkat keparahan kekeringan meteorologis dapat diukur dengan Standardized Precipitation Evapotranspiration Index (SPEI). Salah satu karakteristik kekeringan adalah kondisi vegetasi tanaman yang buruk, oleh karena itu Standardized Vegetation Index (SVI) digunakan sebagai acuan dalam monitoring kekeringan agrikultural. Penelitian ini bertujuan untuk mengetahui hubungan antara SPEI dengan SVI untuk setiap pos hujan di Pulau Lombok tahun 2001-2018. Penelitian ini menggunakan data bulanan tahun 2001-2018 yang meliputi data observasi curah hujan, suhu maksimum, suhu minimum, penginderaan jauh Normalized Differences Vegetation Index (NDVI) dengan resolusi 0,05°, model FLDAS kecepatan angin yang juga didapatkan dengan resolusi 0,5°, lama penyinaran matahari, lintang, dan elevasi. Metode yang digunakan yaitu menghitung indeks kekeringan SPEI dan SVI, kemudian menghitung korelasi dan signifikansi untuk kedua indeks kekeringan tersebut. Hasilnya menunjukkan bahwa SPEI1 lebih tinggi berkorelasi dengan SVI+1 dengan kategori cukup kuat. Untuk SPEI3, SPEI6, dan SPEI12 berkorelasi cukup kuat hingga kuat dengan SVI0. Hal ini menunjukkan bahwa kekeringan jangka panjang akan langsung mempengaruhi kekeringan agrikultural atau kekeringan vegetasi saat itu juga. Nilai korelasi yang lebih tinggi untuk setiap indeks tersebar di pos hujan yang terletak di tengah-tengah Pulau Lombok, karena pengaruh kondisi geografis dan demografis Abstract Drought is a complex disaster because it can cause loss to society in various sectors. One of the high-risk areas of drought is Lombok Island. This area has 405,985 ha of drought risk. The severity of meteorological drought can be measured by the Standardized Precipitation Evapotranspiration Index (SPEI). One of the characteristics of drought is the poor condition of plant vegetation, therefore the Standardized Vegetation Index (SVI) is used as a reference in monitoring agricultural drought. This study aims to determine the relationship of SPEI with SVI for each rainfall post in Lombok Island from 2001-2018. This study uses monthly data from 2001-2018, including observation data of rainfall, maximum temperature, minimum temperature, remote sensing Normalized Differences Vegetation Index (NDVI) 0.05 °, FLDAS model of wind speed 0.5 °, length of the day, latitude, and elevation. The use method is to calculate SPEI and SVI, then calculate the correlation and significance for the two drought indices. The result shows that SPEI1 is higher in correlation with SVI+1, which is in a strong enough category. For SPEI3, SPEI6, and SPEI12, the correlation is strong enough to strong with SVI0. This suggests that long-term drought will directly affect agricultural drought or immediate vegetation drought. The higher correlation values ??for each index are spread over the rain posts located in the middle of Lombok Island because geographic and demographic conditions influence them.

RELIGIOUS EDUCATION AND ADOLESCENT RELIGIOSITY (Part 1: Urban and Rural Madrasah Aliyah Characteristics in Lombok Island)

The current social circumstances at the spiritual level have brought an enormous influence on the establishment of religious behavior in adolescent students, both in the level of belief, practice, and religious experience. Religious education in the madrasah environment has a strategic position in building students' religious behavior. This study aims to explain why the rural and urban madrasah environment context is essential to observe the role of religious education, especially Islamic education, in building students' religious behavior in Lombok island. Then it sorts out the madrasahs characteristics or uniqueness from the two different regions, rural and urban. This research is qualitative psychological research with ecological contextual theory as the theoretical framework. The data analysis method is descriptive and holistic by employing three flows of interacting activities, e.g., reducing data, presenting it, and drawing conclusions. Data was obtained through documentation, observation, and in-depth interviews. This research was conducted in six madrasahs, i.e., two Madrasah Aliyah located in the downtown, and four Madrasah Aliyah, which geographically represent the category of the rural madrasah. The research results indicate that the spiritual development of the students cannot be separated from the religious education context in their environment. In urban areas context, the madrasah environment has formal systemic characteristics, is supported by strong management and leadership, maintains the madrasah stability and conduciveness by implementing a power strategy through a set of rules and code of conduct. Meanwhile, madrasas in rural areas have flexible, dynamic, and adaptive characteristics, in which education takes into account cultural aspects and values applied in the community.

An Analysis of The Level of Polite Utterances in Sasak Language: A Case Study in Central Lombok

This research aims to identify the way of polite language used by Sasak people in Central Lombok. In this research, qualitative descriptive method was employed in analyzing the data. There were three participants that consist of Sasak native speaker from two villages such as Beraim and Dakung village. The data were collected through three techniques that are, observation, interview and documentation. The Results of this research showed that firstly, Sasak language has three levels of polite utterances used by Sasak people such as most polite (Base Alus Utami), more polite (Base Alus Madya), and polite (Base Sasak Biase). When kingdom was exist, Base Alus Utami only used by Perwangse, who was the king or people with high class level in Lombok Island and marked by Raden/Datu, and Dende at the first name. But, when they interacted with the lower class, they used biase language while the lower class of people must use Base Utami then, Base Alus Madya only used by people with the second level in society Baiq and Lalu at the first name, and Base Sasak Biase used by people with the lower class, called Jajar Karang. Secondly, the next generation in Sasak today do not really cosidere the rules when they using the polite language as people used in the past. It can be seen when they are communicating each other. They cannot able to speak with Base Alus Utami even speak with the older people. Only some of old people are still maintenance this language and teach their children but it is so rarely.

Religious Attitude of the Muslim Community of Lombok Island in the Covid-19 Pandemic Season

The Covid-19 pandemic has an impact on changes in the human lifeline, including the pattern of worship of religious people at large. Religious practices that are carried out regularly and implemented in special places are undergoing a shift. The practice of communal worship involving many worshippers is limited at home by involving people who are also limited. This article aims to explain the shift in the way of worship of the people of Lombok Island related to the Covid-19 that hit the world today. The study also exposed a new form of habit in Muslim religious practices due to the pandemic on Lombok island. This article shows that changes in worship patterns are the result of emergencies and the choice to continue to carry out their duties as devout believers. The limitations of the worship space are avoided by adjusting it to government policy. Policies regarding social distancing and adherence to health protocols are an effort to prevent the spread of the virus. In a religious context, it is part of a life-saving effort so it must be obeyed. The new normal requires Muslims to conform and change new habits (new habitus) in carrying out religious practices (prayers). For example, there is a shaf distance, wearing a mask, bringing prayer mats and other equipment needed when praying in the mosque, preparing hand sanitizer in each house of worship, and routinely checking the body temperature of worshippers visiting the mosque and always referring to health protocols guided by Maqosid Assyariah.

Agronomic response of kangkung plants typical of Lombok Island with a hydroponic system treated with Trichoderma bionutrients

The kangkung (Ipomoea aquatica Forsk) is water spinach typical of Lombok Island, Indonesia with a crunchy texture and distinctive taste. It is very easy to be cultivated in the home garden organically in soil media, also to be planted hydroponically and aquaponically. Hydroponic system cultivation is the cultivation of plants by utilizing water without using soil with an emphasis on meeting the nutritional needs of plants. One of the nutrients that has good prospects is the Trichoderma bionutrient which is made from a mixture of bioactivator and biourin. The purpose of this study was to determine the agronomic response of water spinach plants typical of Lombok Island with a hydroponic system treated with Trichoderma bionutrients. The study used an experimental method carried out in a plastic house with a hydroponic system. The study used a completely randomized design with hydroponic nutrition treatment consisting of 6 levels, namely: without bionutrients, with bioactivator bionutrients, with biourin bionutrients, with a mixture of bioactivator and biourin, with AB mix nutrition, with a mixture of Trichoderma bionutrients and Ab mix nutrients. Each treatment was repeated 4 times so that there were 24 experimental units. The results showed that the treatment with a mixture of bionutrients with a mixture of bioactivators and Trichoderma biourin was as good as AB mix nutrition in promoting growth and wet weight of kangkung typical of Lombok Island.
