Ayung river is the longest river in Bali. The middle part of the river is frequently utilized as rafting for tourism, such as in Bongkasa Pertiwi Village, Abiansemal District, Badung Regency – Bali. To preserve the river’s ecological function, the information of riparian vegetation as the dynamic component in river is highly required. This research aimed to study the structure of riparian vegetation in Bongkasa Pertiwi Village. The plot method was used and the study site was divided into three stations. Each station was composed by three replications with four plot variations: trees (20 x 20 m), poles (10 x 10 m), saplings (5 x 5), and herbs-shrubs (2 x 2 m). The data was analysed using vegetation analysis that completed with Importance Value (IV), Shannon-Wiener Diversity Index (H’), Index of Dominancy (C), and Index of Evenness (E). This study found that the structure of riparian vegetation in Bongkasa Pertiwi Village was in good condition which was indicated by the high abundance of local tree species. The floristic composition of riparian vegetation comprised by 18 species of trees, 18 species of poles, 21 species of saplings, and 29 species of herbs and shrubs. Cocos nucifera, Pterospermum javanicum, Bischofia javanica, Cananga odorata, Elaeocarpus serratus, Artocarpus heterophyllus, Coffea canephora, and Nephelium lappaceum were the species with the highest Importance Value (IV). The floor vegetation in form of herbs and shrubs was dominated by Sphaegneticola trilobata, Oplismenus burmanni, and Diplazium esculentum. Based on the Diversity Index (H’), Index of Dominancy (C), and Index of Evenness (E), diversity of riparian vegetation in Bongkasa Pertiwi Village was classified as medium category, without any dominated species, and the vegetation composition was equivalent.

Aspergillus flavus contamination of agriculture in Indonesia can cause problems to animal health and productivity. Some factors can support the appearance of contamination in feed, especially temperature and humidity. The main objective of this research was to investigate potency of Rhizopus spp. on inhibit A. flavus FNCC6109 in broiler chicken concentrate feed. The experiments were conducted dual culture method and the inhibition test of the Rhizopus spp. filtrate culture was incubated for 3, 4 and 5 days on in vitro. The in vivo test was directly applied in broiler chicken concentrate feed which added Rhizopus spp. filtrate culture concentration at 10% (v/v), 20% (v/v), 30% (v/v), 40% (v/v), dan 50% (v/v). The results showed that the Rhizopus spp. filtrate culture significantly (P?0,05) to inhibit the growth of A. flavus FNCC6109 both in vitro and in vivo. The percentage inhibition of Rhizopus spp. filtrate culture incubated for 5 days showed 67,47±2,10% relatively better results than 3 and 4 days, and therefore was used in the in vivo. Application of 50% (v/v) Rhizopus spp. filtrate culture to the broiler chicken concentrate feed significantly reduced 82% population of A. flavus FNCC6109 after 15 days incubated relative to that of negative control (concentrate feed without addition Rhizopus spp. filtrate culture and A. flavus FNCC6109).

Rumput laut Eucheuma cottonii merupakan salah satu jenis rumput laut yang sering dibudidayakan oleh masyarakat adalah Eucheuma cottonii. Berat awal bibit yang ditanam dapat berpengaruh terhadap pertumbuhan rumput laut. Hasil penelitian menunjukkan berat bibit rumput laut yang baik digunakan berkisar antara 50-150 gr, namun belum ada penelitian secara detail pada E. cottonii yang ditaman dengan metode rakit apung. Penelitian ini bertujuan untuk mengetahui berat bibit awal rumput laut yang baik untuk pertumbuhan E. cottonii pada metode rakit apung dengan bibit diletakkan di dalam kantong. Penelitian ini terdiri dari 3 perlakuan yaitu perlakuan A dengan berat bibit 50 gr, perlakuan B dengan berat bibit 100 gr, dan perlakuan C dengan berat bibit 150 gr. Penelitian ini dilaksanakan di Pantai Pandawa, Bali, dari bulan Maret-April 2021, dimana data diambil sekali dalam seminggu selama 7 minggu. Hasil penelitian menunjukkan bahwa pertumbuhan rumput laut meningkat setiap minggunya dan berbeda antar perlakuan. Berat akhir rumput laut pada perlakuan A adalah 558,83 gr, perlakuan B sebesar 552,167 gr, dan perlakuan C sebesar 529,67 gr. Pertumbuhan rumput laut pada perlakuan A lebih tinggi dibandingkan perlakuan B dan C. Rata-rata Specific Growth Rate (SGR) pada perlakuan A adalah 4,92 %, perlakuan B sebesar 3,48 %, dan perlakuan C sebesar 2,57 %. Hasil terbaik dari bibit yang digunakan ditemukan pada bibit dengan berat awal 50g, dibandingkan dengan berat bibit yang lain (p<0,002).

Penelitian ini bertujuan untuk menentukan kandungan timbal (Pb) dan kadmium (Cd) dalam tanaman kangkung air (Ipomoea aquatica Forks.) di rawa yang dialiri limbah cair rumah tangga. Jenis penelitian ini adalah penelitian observasional dilakukan dengan pendekatan deskriptif melalui uji logam berat di laboratorium. Hasil penelitian menunjukkan bagian tanaman yang mengakumulasi logam berat paling tinggi adalah bagian akar, lalu batang, sedangkan daun tidak terkandung logam. Organ akar mengandung logam Pb sebesar 0,0146 mg/kg dan logam Cd sebesar 0,0018 mg/kg. Bagian organ batang mengandung timbal sebesar 0,0012 mg/kg dan logam Cd sebesar 0,000867 mg/kg. Semuanya masih di bawah batas maksimum cemaran logam untuk bahan pangan sehingga masih aman untuk dikonsumsi masyarakat.

Tomat (Solanum lycopersicum L.) merupakan komoditas hortikultura yang memiliki banyak manfaat dan potensial untuk dikembangkan. Permintaan pasar terhadap buah tomat meningkat, namun produksi tomat di Bali mengalami penurunan karena faktor biotik dan abiotik. Upaya untuk meningkatkan pertumbuhan tanaman tomat yaitu menggunakan FMA Glomus sp. dan Trichoderma sp. yang berfungsi sebagai pupuk hayati dan biostimulator. Penelitian dilaksanakan pada November 2020 sampai Februari 2021 dan bertujuan untuk menganalisis pengaruh pemberian FMA, Trichoderma sp. dan kombinasinya terhadap pertumbuhan tanaman tomat. Lokasi penelitian di Greenhouse dan Laboratorium Taksonomi Tumbuhan Prodi Biologi Fakultas MIPA Universitas Udayana. Rancangan penelitian menggunakan Rancangan Acak Kelompok (RAK) Faktorial dengan dua faktor dan tiga kali ulangan. Faktor pertama dosis FMA Glomus (0, 100, 150 dan 200 spora per tanaman), faktor kedua dosis Trichoderma (0, 10 dan 20 mL per tanaman). Data dianalisis menggunakan Analysis of Variance (ANOVA) dan dilanjutkan dengan analisis Duncan Multiple Range Test (DMRT). Hasil penelitian menunjukkan bahwa aplikasi FMA Glomus sp. 150 spora per tanaman dapat meningkatkan tinggi tanaman, panjang akar, jumlah kuntum bunga per tanaman, berat kering total tanaman dan mendapatkan persentase kolonisasi FMA tertinggi sebesar 35% (kategori sedang).

The mosses growth is generally influenced by temperature, habitat humidity, light intensity, and soil acidity. This study aimed to determine the level of diversity of bryophytes species on various substrates in the Nenek Hills Natural Tourism Park of Mount Permisan, South Bangka Regency. The methods used in this study were exploration and observation. The results of this study are the types of mosses (Bryophytes) found Nenek Hills Natural Tourism Park of Mount Permisan, South Bangka Regency, are from the families Calymperaceae, Dicranaceae, Fissidentaceae, Leucobryaceae, Rhizogoniaceae, Sematophylaceae, Calypogeiaceae, Geocalyceae, Lejeuneaceae, Lepidoziaceae and Plagiochilaceae. The dominating family is Leucobryaceae, Lejeuneaceae and Calymperaceae. The type of substrate that moss prefers to grow is rock. Abiotic factors consist of light intensity with a value of 0,2-7,2 Klx (low), air temperature with a value of 25-29°C (medium-high), humidity with a value of 34-68% (medium-high), soil acidity with a value of 5,9-6,9 (slightly-neutral) and soil moisture with a value of 52-65% (moist).

Sehati是马鲁库区(malaku central village)的一个村庄，该村庄拥有kawasanmangrove，占地66.5公顷(22.5公顷)，是当地的旅游景点之一。旅游业支持的建立是为了提高该地区的审美，但也将影响lahanmangrove的运作。由于该地区对塑料垃圾的广泛采伐和强度的增加，红树林正因游客意识不足而减少。旅游业给塞哈蒂村的生态系统红树林带来了相当大的压力。这项研究的目的是分析马鲁库中摄政Sehati村mangrove森林地区的社区结构和皮质环境和水质条件。数据收集是用二次横截面法完成的。该平台使用了5个2×3米的平方(3×3米)的10米，并采用了对水化学参数的各种参数的测量。海滩村发现的一种红树林共有五种。多样性指数(0.965)、高自主权索引(0.893)和中级索引(0.348)。Rhizphora apiculata的密度最高(12 78个ind/m2)，数量最多(23个ind/m2)，出勤率(0.96%)，重要指标(103.56)。水的化学物理因素状况仍然有利于红树林的生长。
