Abstract

Red pepper plants (Capsicum annum L.) are one of the most important horticultural commodities in Indonesia. One effort to increase the growth and yield of red pepper is by using biological soil fertilizers, namely Trichoderma, sp. Andisol is a type of soil with loose and fragile texture conditions, making this type of soil very easily carried away by rainwater, wind and landslides or experiencing erosion. This study aims to see the effect of Trichoderma sp on the growth and yield of red chili plants (Capsicum annum L.) on Andisol soil, which was carried out at the Experimental Garden of the Faculty of Agricultural and Animal Husbandry Sciences UNIKI and the UNIKI Faperta Laboratory, the study used a Randomized Block Design Factorial Pattern (RAK) 3 × 3 with 3 replications, so that it has 9 with a combination of treatments of 20 grams, 25 grams and 30 grams. The best growth of chili plants was found at a dose of 30 grams of Trichoderma and the best chili plant results were found at a Trichoderma dose of 25 grams.

Abstract

Abstract Coffee is cultivated in almost all regions of Indonesia, but the main coffee producing provinces in Indonesia are Aceh, North Sumatra, South Sumatra, Lampung, East Java and South Sulawesi. Sampling was carried out in Pedemun Village, Lut Tawar District and Weh Nareh Village, Pegasing District, Central Aceh Regency. Identification of rhizobacteria was carried out at the Plant Disease Laboratory, Department of Plant Protection, Faculty of Agriculture, Syiah Kuala University, Banda Aceh. implemented from May to July 2023. This research was conducted using qualitative descriptive methods. Sampling was determined by purposive sampling, namely deliberately (without random). The results of the isolation of rhizobacteria in the rhizosphere area of coffee plants resulted in 9 isolates with different codes for each isolate, namely: DP1, DP2, DP3, DP4, PD5, KS1, KS2, KS3, and KS4. Each isolate has different macroscopic characteristics, namely having irregular (irregular) and circular (circular) colony shapes, undulate (wave-like) and entire (flat) colony edges as well as smooth and butyrous (like butter) textures. The staining test results show that all types of isolates include Gram-negative bacteria which are marked in red. All types of isolates obtained had the same cell shape, namely bacilli.

Abstract

Catfish farming is one of the businesses that is very much in demand by the community, because it can improve the community's economy. However, not all catfish farming businesses can produce maximum results. This can be caused by several factors, both from feed, management and water quality. Decrease in water quality can be caused by feces and fish feed residue. Poor water quality can cause the growth process, physiology and level of fish behavior to be disturbed. Efforts that can be done is to use aquatic plants as phytoremediation. The plants used in this study were Azolla sp, Eichhornia crassipes, Lemna sp, Ipomoea aquatic. The design used in this study was a completely randomized design with 4 treatments and 3 replications. The parameters observed in this study were ammonia levels, pH, and plant population. The results showed that Eichhornia crassipes and Lemna sp were able to reduce ammonia levels in catfish cultured water by 0.01 mg/l at the end of the study.Keywords:AmmoniaWater plantsCatfish

Abstract

Sclerotium rolfsii Sacc. merupakan jamur penyebab penyakit rebah kecambah pada tanaman kedelai (Glycine max L.) yang menyebabkan penurunan produksi kedelai. Salah satu upaya untuk meningkatkan ketahanan tanaman kedelai terhadap serangan patogen S. rolfsii adalah dengan menggunakan agen hayati T. harzianum. Tujuan dari penelitian ini untuk mengetahui dosis pelet T. harzianum yang tepat untuk menekan pertumbuhan cendawan patogen Sclerotium rolfsii penyebab penyakit rebah kecambah pada tanaman kedelai. Metode penelitian menggunakan Rancangan Acak Kelompok Non Faktorial (RAK), dengan 6 perlakuan dan diulang sebanyak 5 kali sehingga diperoleh kombinasi perlakuan sebanyak 30 unit tanaman. Data dianalisis menggunakan Analysis of Variance (ANOVA), didapatkan hasil yang berbeda nyata α<0,05 dilanjutkan dengan analisis BNJ 5%. Hasil penelitian menunjukkan T. harzianum dengan dosis 20 gram/tanaman berpengaruh menurunkan intensitas penyakit rebah kecambah yang disebabkan cendawan patogen S. Rolfsii dan masa inkubasi perlakuan yang terserang lebih cepat yaitu pada perlakuan kontrol (VD0), Trichoderma harzianum dengan dosis 10 gram/tanaman (VD1) sedangkan perlakuan yang paling lambat terserang penyakit yaitu perlakuan Trichoderma harzianum dengan dosis 30 gram/tanaman (VD5).
