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.

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.

This study is motivated by the widespread practice of retail gasoline trading in Pematang Rahim Mendahara Ulu Village, which has emerged as a community-based response to limited access to formal fuel distribution channels and pressing local economic needs. The research aims to examine these transactional practices through the lens of Islamic business ethics and Islamic economic law, with particular attention to contractual clarity (akad), price fairness, measurement transparency, and the potential presence of gharar (uncertainty). Employing a qualitative field-based approach with a case study strategy, data were collected through direct observation, in-depth interviews with retailers and consumers, and supporting documentation. The data were subsequently analyzed using thematic analysis techniques. The findings indicate that retail gasoline transactions operate informally and are largely grounded in interpersonal trust; however, several issues persist, including inconsistent measurement standards, price fluctuations, and concerns related to distribution legality. Conceptually, this study contributes to the development of Islamic economic ethics discourse within informal market settings and offers practical implications for strengthening ethical business literacy and improving local-level energy distribution governance.
