Abstract

Water pollution refers to the introduction of living organisms, substances, or other components by human activities that can degrade water quality or cause environmental harm. Gonad maturity level indicates the stage of readiness of prospective broodstock for the spawning process, assessed through visual and histological methods. This study aimed to assess water quality in the Way Awi River based on fish community structure and to evaluate the impact of sewage discharge on fish gonad maturity levels in Bandar Lampung's Way Awi River. Conducted between November and December 2023, this research sampled five points along the Way Awi River. Chemical analysis included pH, BOD, COD, and DO, while physical parameters such as temperature and TSS (Total Suspended Solids) were also analyzed. The findings indicate that the Way Awi River is moderately polluted, with no significant impact on the community structure, although there is a noticeable decrease in fish numbers from upstream to downstream. This study underscores the importance of understanding the risks associated with continuous disposal of waste into rivers.

Abstract

Hormon AIA berperan besar dalam memperbesar dan memperpanjang sel, pembelahan sel, khususnya pada daerah ujung tanaman. Bakteri yang memiliki kemampuan dalam menghasilkan hormon AIA diantaranya  Enterobacter sp., Azospirillum sp., Klebsiella sp., Alcaligenes faecalis, Azoarcus sp., Serratia sp., Azotobacter sp., Cyanobacteria, Erwinia herbicola, Pseudomonas sp., Rhizobium, Bradyrhizobium, Agrobacterium tumafaciens. Sintesis AIA ini memerlukan senyawa tambahan berupa triptopan. Namun beberapa bakteri mampu memproduksi AIA tanpa penambahan prekursor. Penelitian ini bertujuan untuk memperoleh isolat bakteri penghasil hormon AIA dari tanah Kebun Raya Liwa. Pada ini diawali dengan isolasi bakteri tanah asal Kebun Raya Liwa, selanjutnya dilakukan uji kemampuan produksi AIA secara kuantitatif tanpa penambahan triptopan. Pengujian produksi AIA secara kualitatif dilakukan dengan menggunakan media Nutrien Broth dengan metode spektrofotometri dengan penambahan reagen salkowsky dan dilakukan pengamatan setelah 72 jam inkubasi. Data yang didapatkan disajikan dalam bentuk tabel. Hasil penelitian didapatkan 9 isolat yang mampu menghasilkan hormon AIA dengan kadar yang berbeda. Isolat penghasil AIA tertinggi yaitu isolat DT1 dengan kadar 114 ppm yang mempunyai karakteristik berbentuk bacil berwarna putih susu dan tidak berspora.     AIA hormone plays a role in enlarging and elongating cells, and cell division, especially at the tip of the plant. Bacteria that have the ability to produce IAA hormones include Enterobacter sp., Azospirillum sp., Klebsiella sp., Alcaligenes faecalis, Azoarcus sp., Serratia sp., Azotobacter sp., Cyanobacteria, Erwinia herbicola, Pseudomonas sp., Rhizobium, Bradyrhizobium, Agrobacterium tumafaciens. The synthesis of AIA requires an additional compound in the form of tryptophan. However, some bacteria can produce AIA without the addition of precursors. The goal of this study was to obtain isolates of AIA hormone-producing bacteria from the soil of the Liwa Botanical Gardens. This begins with the isolation of soil bacteria from the Liwa Botanical Gardens, then a quantitative test of AIA production capability is carried out without the addition of tryptophan. Qualitative testing of AIA production was carried out using Nutrien Broth media with spectrophotometric methods with the addition of Salkowsky reagent and observations were made after 72 hours of incubation. The data obtained are presented in tabular form. The results showed that 9 isolates were able to produce the AIA hormone at different levels. The highest AIA-producing isolate was the DT1 isolate with a concentration of 114 ppm which had the characteristics of a milky white bacillus and no spores.

Abstract

Tanah Kebun Raya Liwa (KRL) Lampung Barat merupakan tanah jenis laterit yang kandungan unsur hara dan kesuburan tanahnya rendah, sehingga tidak dapat mendukung pertumbuhan tanaman hias yang ada secara optimal. Salah satu unsur hara yang penting dalam menunjang kesuburan dan pertumbuhan tanaman adalah fosfat. Jumlah fosfat terlarut dalam tanah yang dapat dimanfaatkan oleh tanaman sangat sedikit sehingga menyebabkan defisiensi. Bakteri pelarut fosfat asli dibutuhkan untuk memenuhi kebutuhan fosfat bagi tanaman. Tujuan dari penelitian ini adalah untuk mendapatkan isolat bakteri pelarut fosfat yang berpotensi melarutkan fosfat. Penelitian ini dilaksanakan pada bulan Maret sampai Juni 2021 meliputi isolasi bakteri pelarut fosfat dan pengujian potensi pelarutan fosfat pada media pikovskaya padat. Potensi bakteri pelarut fosfat ditentukan berdasarkan nilai Indeks Kelarutan Fosfat (IPF) tertinggi. Hasil isolasi tanah dari Kebun Raya Liwa diperoleh 10 isolat yang mampu melarutkan fosfat dan menghasilkan zona bening. Isolat dengan potensi pelarutan fosfat terbaik adalah isolat C1 dan C3 dengan nilai indeks pelarutan fosfat 2, 6 dan 2.       Liwa Botanical Gardens (KRL) soil, West Lampung is a lateritic soil type nutrient content and low soil fertility, so it can’t support the growth of existing ornamental plants optimally. One of the important nutrients in supporting fertility and plant growth is phosphate. The amount of dissolved phosphate in the soil that can be utilized by plants is very small, causing a deficiency. Indigenous phosphate solubilizing bacteria are needed to meet the needs of phosphate for plants. The purpose of this study was to obtain isolates of phosphate solubilizing bacteria that have the potential to dissolve phosphate. This research was carried out from March to June 2021 covering the isolation of phosphate solubilizing bacteria and testing the potential for dissolving phosphate on solid pikovskaya media. Potential phosphate solubilizing bacteria were determined based on the highest Phosphate Solubility Index (IPF) value. The results of soil isolation from Liwa Botanical Gardens obtained 10 isolates capable of dissolving phosphate and producing a clear zone. Isolates with the best phosphate solubilizing potential were isolates C1 and C3 with phosphate solubilizing index values of 2, 6 and 2.

Abstract

Sungai Way Umpu merupakan sungai yang berada di Kabupaten Way Kanan, Lampung. Sungai ini sebagian besar digunakan oleh masyarakat Kabupaten Way Kanan sebagai sumber air dalam aktivitas bidang pertanian, perkebunan, perikanan, industri, dan kebutuhan domestik masyarakat. Adanya aktivitas tersebut dapat mempengaruhi kualitas air sungai baik fisika, kimia, maupun biologi. Hal ini akan memberikan tekanan ekologis dan peningkatan pencemaran di perairan sungai dan mempengaruhi keberadaan biota perairan terutama ikan sebagai konsumen dalam ekosistem sungai yang akan mempengaruhi keberadaan dan kondisinya. Ikan sebagai salah satu bioindikator status lingkungan perairan, untuk mengetahui kualitas perairan Sungai Way Umpu dapat diketahui dengan menghitung nilai Nutrition Value Coefficient (NVC). Penelitian ini menggunakan metode survei, penentuan titik sampling dilakukan berdasarkan tata guna lahan. Sampel pada penelitian ini adalah ikan yang ditemukan di lokasi stasiun pengamatan. Ikan yang telah diperoleh langsung diukur berat dan panjangnya lalu nilai NVC ikan dihitung dengan rumus Fulton. Ikan yang digunakan sebagai perhitungan NVC adalah Ikan Tawes Kepek. Hasil menunjukkan kualitas Sungai Way Umpu berdasarkan NVC Ikan pada ST-1, ST-2, ST-4 dan ST-5 tercemar ringan sedangkan pada ST-3 sama sekali tidak ditemukan ikan sehingga diduga lokasi ini tercemar berat. Hubungan nilai NVC Ikan dengan parameter fisika kimia berdasarkan korelasi pearson memiliki hubungan yang sangat kuat dan signifikan antara nilai NVC ikan dengan nilai kekeruhan, TSS, pH, BOD, dan COD.    Kata kunci: Ikan, Bioindikator, Kualitas Perairam, Nutrition Value Coefficient (NVC), Sungai Way Umpu

Abstract

Soil macrofauna are important bioindicators of soil fertility. Soil fertility is strongly influenced by soil conditions, which affect the presence and density of macrofauna populations through the decomposition of organic matter. This study aimed to determine the diversity of soil macrofauna across different habitat types in the Batutegi Protection Forest (BPF), Tanggamus, Lampung. The methods used included pitfall traps, point counts, and hand sorting. Three plots were set up, each with three pitfall traps. The point count method involved walking a 100-meter transect with 10 stopping points, each observed for 10 minutes. The hand sorting method was conducted in three 25 × 25 cm plots at a depth of 20 cm. The soil macrofauna diversity indices obtained using the pitfall trap method were as follows: river border (H'=2.9), shrub area (H'=3.1), and forest interior (H'=3.1). Using the point count method, the diversity indices were: river border (H'=3.5), shrub area (H'=2.8), and forest interior (H'=3.3). The diversity indices from the hand sorting method were: river border (H'=2.7), shrub area (H'=2.4), and forest interior (H'=1.8).

Abstract

One type of household waste that is commonly discarded and rarely reused is banana peel waste. If left unmanaged, it can cause environmental problems in both rural and urban areas. An alternative solution is to utilize banana peel waste, such as Ambon banana peels, as a source of local microorganisms for producing liquid organic fertilizer (POC). POC is relatively easy to produce and environmentally friendly. This community service program aimed to empower residents of Dasawisma Dahlia RT 004, Labuhan Ratu, Bandar Lampung, through training on the production of liquid fertilizer concentrate (LFC) from Ambon banana peels. The results showed an increase in participants’ knowledge and skills, as reflected in the average pre-test score of 60.51, which increased to 86.67 after the post-test. This represents an improvement of 26.15 points, or a 43.22% increase. The sustainability of this initiative lies in the potential for large-scale POC production, which can be further utilized for environmental and economic benefits.
