Abstract

A healthy and sustainable environment is critical for sustaining ecological balance and increasing human well-being. However, other human activities, such as industrialization, urbanization, and the use of chemicals in agriculture, can have a negative impact on the environment. As a result, the community requires an effective and simple way for integrating their surroundings. Bioindicator-based analysis is one approach of assessing environmental quality. Bioindicators are creatures whose presence, quantity, or physical condition can reflect the state of their surroundings. Plankton, macrozobenthos, moss, lichen, soil insects, and other microorganisms are examples of bioindicators. This community service project seeks to raise public awareness of the significance of bioindicators in environmental quality assessment, as well as how to identify the many types of bioindicators found in the surrounding environment and how to utilize them to assess air, soil, and air quality. The community service activity is divided into three stages: preparation (site survey and activity needs, permissions), implementation (socialization and poster exhibition), and assessment (participants completing questionnaires). The community service activity ran successfully. Throughout the socialization activities, all participants were engaged and eager. The material supplied was fresh to the participants and would be fascinating to examine further. Furthermore, participants were interested in attempting to determine environmental quality by observing the presence of bioindicators around them. Socialization activities were also able to instill in participants a sense of awareness and concern for environmental changes, prompting them to take an active role in sustaining the ecosystem in their surrounds.

Abstract

The development of shade trees on the Mataram University campus is intended to maintain environmental comfort, as well as add beauty. The microclimate softening function of trees is largely determined by the density of their canopies, known as the leaf area index (LAI). Various LAI measurement methods have been developed, which are generally more suitable for assessing tree productivity but less valid for assessing the ability to soften the microclimate or decrease the discomfort index (DI). This study was conducted to analyze the distribution of LAI of shade trees and their relationship with the DI on the Mataram University campus. To obtain a more valid LAI value, the leaf area variable measured was the leaf area forming the canopy, replacing the leaf area on the canopy surface, as was done in previous studies. Microclimate variables measured to determine the discomfort index (DI) were air temperature and relative humidity. The results showed that the LAI of 108 trees (33 species) spread across 9 zones within the Mataram University campus ranges from 1.2630 (very small category) to 9.6735 (very large category). The DI values under the canopy of trees ranged from 23.225 (quite comfortable category) to 26.869 (somewhat comfortable category). The relationship between LAI of shade trees and DI on the campus of Mataram University was linear and negative, with the resulting regression equation being y = 28.1204-0.4749x. If LAI increased, then DI tended to decrease; conversely, if DI increased, then LAI tended to decrease. The function of campus trees in softening the microclimate can be enhanced by improving their LAI.

Abstract

Dusun Murpeji Desa Dasan Griya merupakan daerah perbatasan antara kota Mataram dengan kabupaten Lombok Barat. Mata pencarian sebagai besar masyarakat adalah petanian dan perkebunan. Desa ini merupakan desa yang sangat subur karena terdapat banyak sumber mata air dan sungai yang mengaliri sebagian besar sawah masyarakat. Masyarakat belum maksimal memanfaatkan pekarangan mereka untuk sumber obat keluarga, beberapa lahan juga dibiarkan kosong, kebun masyarakat juga banyak ditumbuhi oleh tumbuhan liar yang memiliki potensi sebagai sumber obat yang belum termanfaatkan. Tumbuhan obat lokal sejauh ini belum dikenal dan dimanfaatkan secara maksimal oleh masyarakat. Luaran dari kegiatan pengabdian ini adalah adanya kebun obat masyarakat di dusun Murpeji berbasis tumbuhan lokal untuk peningkatan kesehatan dan kesejahteraan keluarga. Kebun obat juga diharapkan sebagai wadah untuk kegiatan konservasi masyarakat dengan memperbanyak dan membudidayakan tumbuhan lokal sebagai sumber plasma nutfah. Metode yang digunakan dalam kegiatan ini adalah Focus Group Discuss (FGD) untuk menentukan kebutuhan dan jenis kegiatan yang sesuai dengan sasaran dan praktik langsung sejak mulai dari persiapan hingga akhir kegiatan. Kegiatan pelatihan pembuatan obat menggunakan pola pembimbingan dimana masyarakat dirangsang untuk terlibat langsung dalam proses pembuatan produk dan membentuk kelompok kerja bersama. Hasil kegaiatan pengabdian di Dusun Murpeji menunjukkan antusiasme tinggi dari peserta. Masyarakat telah memiliki pengetahuan dasar terkait jenis, manfaat, dan teknik budidaya tumbuhan obat meskipun masih terbatas. Keberhasilan kegiatan pengabdian dapat dilihat dari peningkatan pengetahuan masyarakat dari yang awam tentang tumbuhan obat menjadi tahu terkait tumbuhan yang dapat dimanfaatkan sebagai obat dan adanya peta tumbuhan obat di dusun Murpeji berbasis pengetahuan masyarakat.

Abstract

The Mandalika Coastal Area, located in Central Lombok Regency, is a row of beaches and bays that have a large coral reef ecosystem and intertidal zone area. The increasing growth of activities on the Mandalika coast will affect the life of the coral reef ecosystem, one of which is the concentration of heavy metals that exceeds the quality standard limits which will be very dangerous for coral reefs. This study aims to determine the concentration of the heavy metals lead and cadmium in Porites lutea coral reefs in Kuta, Tanjung Aan and Gerupuk beaches. Research data collection (field and laboratory) was carried out in May 2023. Coral reef preparation was carried out at the Advanced and Analytical Biology Laboratory, FMIPA, University of Mataram and measurements of heavy metal content were carried out at the Environmental Laboratory, the West Nusa Tenggara Province Environment and Forestry Service. Measurement and calculation of heavy metal content using Atomic Absorption Spectrophotometry (AAS). The results showed that the concentrations of the heavy metals lead and cadmium in Porites lutea coral reefs are < 0.0005 mg/L and < 0.0001 mg/L, which are still below the quality standards (PPRI No.22 of 2021 concerning Sea water Wuality Standards on Marine Biota). The Bioaccumulation Factors (BAF) value in all samples of P. lutea coral in Mandalika coastal waters is 0.00 mg/L, this shows that there is no accumulation of heavy metals in P. lutea coral.
