Abstract

The legal age of marriage in Indonesia is a man and woman who have reached the age of 19 as stated in Law Number 16 of 2019 on the amendment of Law Number 1 of 1974 concerning marriage in Indonesia. Marriage under the age of 19 is called early marriage, which is known as the "Merariq Kodeq" tradition for the Sasak tribe in West Nusa Tenggara. The purpose of this research is to find out the ethnobiological perspective of the Merarik Kodeq culture in West Lombok and find out the efforts that have been made by the local government of West Lombok Regency to prevent the increasing prevalence of Merarik Kodeq West Lombok. This research uses descriptive qualitative methods. The informants involved in this study were selected using a purposive sampling technique based on predetermined criteria, namely couples who married at an early age. The results stated that the average age of early marriage in West Sekotong Village is 16-17 years old. At this age, the reproductive organs are still in the developmental stage, especially the female reproductive organs which will function as a place for the development of the fetus. So if a pregnancy occurs at this age, there will be a high risk of miscarriage, birth defects, and even death of the mother and baby. So that to address the increasing number of Merarik Kodeq or early marriages the local government formed a movement known as the Anti Merarik Kodeq Movement (GAMAK).

Abstract

This study aims to assess the impact of the use of used oil and High Density Polyethylene (HDPE) plastic as additives in asphalt mixtures modified with Asbuton on fatigue resistance in AC-BC mixtures. This mixture is designed with an optimal asphalt content of 6.0% and combined with variations in the proportion of modified Asbuton asphalt and oil asphalt. Testing was carried out using the Indirect Tensile Fatigue Test (ITFT) method at a pressure of 500 kPa and at a temperature of 20 degrees Celsius to evaluate fatigue performance due to repeated loads. The results showed that increasing the proportion of modified asphalt containing Asbuton, used oil, and HDPE resulted in a significant increasing trend in the fatigue life of the tested specimens. These findings indicate that asphalt modification with a combination of these waste materials can increase the flexibility and resistance of the mixture to repeated loads. This study contributes to the development of more environmentally friendly road pavement materials with better performance.

Abstract

This study aims to analyze the effect of driving behavior on pollution on the island of Lombok. This study is a study with a Completely Randomized Design (CRD). Data collection was carried out by distributing questionnaires to respondents who met the criteria as respondents. This equation contains positive and negative statements that aim for respondents to read the statements carefully and answer with their own perceptions. The questionnaire in this study uses a Likert scale of 1-5 in measuring respondent perceptions. This study shows that driving behavior on Lombok Island has a significant influence on air pollution levels, especially in urban areas such as Mataram which have high traffic density. This pollution is caused by aggressive driving behavior, such as sudden acceleration and sudden braking, as well as low vehicle maintenance that increases exhaust emissions such as CO, NOx, and PM2.5. The impact not only reduces air quality and damages the ecosystem, but also increases cases of respiratory diseases such as ARI and asthma. Science-based solutions, such as the use of environmentally friendly vehicles, development of public transportation, and energy-efficient driving education, need to be implemented to reduce pollution and maintain environmental sustainability in Lombok.

Abstract

Pelaksanaan pengabdian bertujuan untuk menumbuhkan rasa empati terhadap berbagai permasalahan yang ada dilingkungan Masyarakat dan juga mewujudkan salah satu implementasi Tridharma perguruan tinggi yaitu berupa pemberdayaan Masyarakat. Desa Pendem merupakan salah satu desa dari 12 wilayah yang ada pada Kecamatan Janapria, Kabupaten Lombok Tengah. Kondisi tanah Desa Pendem yang subur menjadi potensi dilakukannya penanaman bibit pohon maupun bibit buah. Melihat kondisi tanah yang mendukung tim pengabdian melakukan pembagian bibit tanaman di daerah desa pendem. Kegiatan penanaman bibit pohon maupun bibit buah meliputi perencanaan penanaman, persiapan penanaman, dan proses penanaman. Pembagian dan penanaman bibit pohon ini diharapkan dapat memberikan keuntungan baik dari segi lahan, juga dapat meningkatkan komoditas Desa Pendem. Selain itu juga kegiatan ini diharapkan bisa memberikan sumbangsih kepada kelestarian lingkungan desa Pendem dan beriorientasi pada perencanaan Desa wisata yang sekiranya ada di Desa Pendem Kecamatan Janapria. Kegiatan program pengabdian secara keseluruhan dapat dikatakan baik dan berhasil, berdasarkan pengukuran tiga komponen. Tiga komponen tersebut yaitu kesesuaian dengan keinginan masyarakat, kerjasama pengabdian bersama masyarakat, dan Peningkatan pengetahuan masyarakat untuk menjaga lingkungan.

Abstract

Asbuton is a natural raw material that has great potential in the development of high-quality asphalt mixtures. To optimize its performance, this study explored the use of additives in the form of used oil and high density polyethylene (HDPE) plastic, which is considered to be able to increase the flexibility, adhesion, and stability of the mixture. The commonly used Marshall method is considered less representative in measuring the indirect tensile stiffness of mixtures which is important for assessing elastic response, so Indirect Tensile Stiffness Modulus (ITSM) testing is used to obtain a more comprehensive picture of the performance of asbutone mixtures. This study uses an AC-BC mixture where the Asphalt content is in a combination of Modified Asphalt (MO) and Oil Asphalt (MI), this modified asphalt uses Asbuton which is given an added ingredient of used Oil and HDPE Plastic, this study uses KAO of 6.0% of the total weight of the test object, from the percentage of this KAO combined with 3 compositions of Asphalt mixture, namely Modified Asphalt with Oil Asphalt. Namely 40% Modified Asphalt: 60% Oil Asphalt, 50% Modified Asphalt: 50% Oil Asphalt, and 60% Modified Asphalt: 40% Oil Asphalt, resulting in consecutive ITSM values of 6124 Mpa, 6286 Mpa, and 6738 Mpa. From these results, it can be concluded that with the increase in the composition of modified asphalt, it increases the rigidity of the test specimen.

Abstract

Salah satu Desa di Lombok Tengah yang berada di Kecamatan Pringgarata adalah Desa Pemepek. Desa ini memiliki potensi wisata alam yang indah dan sangat menarik jika dilihat dari sisi keasrian ataupun keasliaan alam Desa Pemepek. Namun hal tersebut tidak luput dari permasalahan sampah terutama sampah plastik. Hingga kini belum ada aturan yang memuat tentang pembuangan sampah plastik. Akibatnya, banyak sekali sampah plastik yang tampak berserakan di pinggir jalan bahkan di beberapa tempat wisata yang seharusnya memiliki nilai estetika tinggi dan menarik bagi wisatawan, tapi jadi malah kelihatan kumuh dan kurang bisa menarik simpati wisatawan karena adanya sampah plastik. Oleh karena itu, program pengabdian ini bertujuan untuk melakukan sosialisasi dalam menyelesaikan bersama persoalan desa Pemepek yakni keberadaan sampah-sampah yang mengganggu nilai estetika tempat wisata tersebut. Tim pengabdian dibantu oleh mahasiswa KKN PMD Universitas Mataram Desa Pemepek mengadakan program kerja pembuatan tempat sampah dari bambu, yang diharapkan dapat mengedukasi masyarakat lokal dan wisatawan mengenai pentingnya pembuangan sampah pada tempat yang tepat untuk pelestarian alam sehingga dapat menciptakan suasana desa dan tempat wisata menjadi bersih, indah, asri dan sehat. Salah satu cara yang dilakukan adalah dengan membuat tempat sampah dari Bambu sehingga bisa digunakan untuk tempat pembuangan sampah.
