The history of nickel mining in Indonesia began in the Verbeek Mountains in Sulawesi in 1901. The finding of nickel and its extraction occurred in the Netherlands, making it the pioneering site for this ore. Also, the substantial rise in the extraction of natural resources like nickel through mining would inevitably profoundly influence forests, which serve as the core of the ecosystem for both flora and fauna. This study aims to determine the consequences of the growing nickel production on Indonesia’s forests and environment. It involves examining the alterations in the forests due to the increased nickel production and evaluating the broader environmental effects. The research method used in this research is a literature review. This technique seeks to analyze, assess, and interpret diverse research findings to examine them within the investigated subject’s framework. The research result of this investigation demonstrates that the escalating nickel production in Indonesia is detrimental to forests and the environment, leading to deforestation, degradation of habitats, and contamination of the air and soil. These alterations present immediate hazards to human well-being, such as respiratory problems and effects on agricultural output. It is crucial to evaluate and improve the methods used for nickel production and adopt sustainable management strategies to reduce the negative impacts on the environment and protect both the ecosystem and human welfare. Keywords: ecosystem pollution, deforestation, forest management, nickel mining, water pollution

Makrozoobentos merupakan invertebrata yang masa hidupnya dihabiskan di dasar perairan atau di atas sedimen. Penelitian ini bertujuan untuk mengkaji struktur komunitas makrozoobentos sebagai bioindikator kualitas air di Sungai Way Awi, Bandarlampung. Penelitian dilakukan pada Oktober-Desember 2023. Pengambilan sampel makrozoobentos menggunakan Ekman grab di lima stasiun mewakili hulu, tengah, dan hilir sungai. Analisis dan identifikasi sampel dilakukan di Laboratorium Zoologi FMIPA Universitas Lampung dengan bantuan buku identifikasi Fresh-Water Biology. Hasil penelitian berhasil mengidentifikasi 8 genus makrozoobentos yang terdiri dari phylum Mollusca, Arthropoda, dan Annelida. Struktur komunitas menunjukkan kondisi indeks keanekaragaman yang rendah (H’ < 1), indeks keseragaman sedang hingga tinggi (0,4 < E < 1), indeks dominansi sedang hingga tinggi (0,30 < C < 1), dan indeks kekayaan jenis rendah (Dmg < 2,05). Analisis korelasi antara struktur komunitas dan pengukuran sifat fisika-kimia badan air menunjukkan adanya hubungan signifikan antara oksigen terlarut (DO) dengan indeks keseragaman dan indeks dominansi. Berdasarkan hasil tersebut dapat disimpulkan bahwa parameter fisika-kimia perairan memiliki peran dalam menentukan struktur komunitas makrozoobentos dan dapat dijadikan sebagai indikator dalam penilaian kualitas air.

Banjar Agung Udik village is an area in Pugung Sub-District, Tanggamus Regency, which is located close to Mount Tanggamus. This activity aims to provide training on making biopore infiltration holes in an effort to conserve groundwater in the yard, with the aim of increasing the absorption of rainwater into the soil. This training is expected to reduce the risk of flooding due to rainwater and increase the amount of clean water reserves in the soil. This activity was held on August 6, 2024, at the Banjar Agung Udik village hall, with participants from various age groups, both men and women. The activity began with problem analysis through field surveys, followed by the preparation of an activity plan, training implementation, and ended with socialization and guidance on making biopore infiltration holes in an effort to conserve groundwater in home yards. With continuous training, it is expected that participants will gain knowledge and skills that can be used to reduce the risk of flooding due to overflowing rainwater and to increase the amount of clean water reserves in the soil.

Fly ash merupakan salah satu limbah pembakaran batubara. Fly ash mempunyai kandungan bahan anorganik yang memiliki unsur dan logam berat. Fly ash dapat dimanfaatkan untuk bahan adsorben, tambahan pada industri semen dan pembenah lahan (soil conditioner). Namun kandungan logam berat pada fly ash tidak mampu diurai oleh lingkungan dan berpotensi terakumulasi pada organisme. Metode bioassay adalah metode yang digunakan untuk mengetahui pengaruh suatu bahan terhadap organisme. Metode ini memaparkan suatu bahan secara langsung terhadap organisme uji. Dapnia magna merupakan salah satu organisme yang digunakan sebagai organisme standar dalam uji bioassay. Penelitian ini bertujuan untuk mengetahui nilai LC50 96 jam pemaparan fly ash terhadap hewan uji. Konsentrasi yang digunakan pada uji sesungguhnya berupa 14.000, 21.000, 30.000, 45.000, 65.000, 94.000, 137.000, dan 199.000 ppm. Hasil penelitian menunjukan nilai LC50 96 jam berada pada estimasi kosentrasi 50.251 ppm. Berdasarkan kriteria toksisitas, nilai LC yang didapatkan masuk ke dalam kategori almost non toxic.

Abstract: The microbial distribution pattern or dispersion of microbes in a water environment was the primary focus of this research. The study aimed to analyze the total density of Vibrio sp., coliform, and plankton in seawater, as well as the relationship between microbes and the hatching of vanamei shrimp larvae. The research was conducted from April to August 2022 at Pantai Ketang, Kalianda, Lampung, in the Microbiology and Zoology laboratory of the Faculty of Mathematics and Natural Sciences, Lampung University. The research employed an exploratory survey method, including the calculation of total Vibrio, coliform, plankton, and survival rates. Data analysis was carried out using analysis of variance, followed by the Duncan test (? = 0.05) for identifying significant differences among groups. Additionally, the microbial relationship was analyzed using Pearson correlation (? = 0.05). The results revealed that the highest Vibrio density occurred in May (3 CFU/ml) and in larval shrimp rearing water (M) (5 CFU/ml). Coliform density was less than < 3 MPN/100ml, and the highest plankton density was observed in August (2×102 ind/L) and in high tide seawater (P) (1×104 ind/L). However, there was a very low correlation between microbial density and the survival rate of vanamei shrimp larvae.

The Faculty of Mathematics and Natural Sciences (FMIPA) as one of the faculties at the University of Lampung has many trees that produce organic waste in the form of leaf litter every day, and this is very potential to be used as a substrate for compost. Compost is the final substance of a fermentation process of piles of waste/plant litter and sometimes also includes animal carcasses. In the open, compost can occur on its own, through natural processes. However, the process takes a long time while the need for fertile soil is urgent. Therefore, the process needs to be accelerated with the help of microorganisms. This community service activity is a form of application of science and technology by inducing leaf debris as compost material with saprotroph fungi inoculum. Saprotroph fungi isolates are very potential to be developed into composting inoculum in making organic fertilizers. Compost induced with this fungal inoculum is expected to produce organic fertilizer relatively quickly and contain high plant nutrients. The results of the Community Service showed quite good results, namely an increase of about 88.4% from the initial understanding. This is quite interesting because the initial understanding of compost and inoculum was relatively low at 25.04%. After the explanation given by the Community Service team, it was able to be understood by the target audience well so that their understanding increased to 63, 6%.
