Abstract

Sorghum is a cereal crop with potential for food security. In West Kalimantan, sorghum production and development are still lacking, especially in peatlands. Peatlands have serious constraints such as low pH, toxic compounds for plants, nutrient deficiencies, high nutrient leaching and low base saturation, and inhibition of nutrient absorption. This the study's objective is to ascertain the diversity of growth and yield of several sorghum varieties in peatlands. The study was conducted on street Sepakat 2, Pontianak City, with a research period of approximately 4 months starting in September-December 2023. This study used a Completely Randomized Design (CRD) with 6 treatments of sorghum varieties and 4 replications. The varieties used were Bioguma 1, Bioguma 3, Super 1, Kawali, Soper 6, and Soper 9. The parameters examined in the research encompassed  plant height, stem girth, leaf count, dry weight of plants, root volume, panicle length, dry weight of 100 seeds, and dry weight of seeds per crop. The results of the study showed that there is diversity of growth and yield of several sorghum varieties in peatlands. The variety suitable for planting in peatlands is the Super 1 variety and Kawali.

Abstract

Melada is a member of the Piperacea family, which is a perdu. Melada plants have properties that are resistant to the fungal attack Phytophthora capsici that causes basal stem rot disease; therefore, melada plants are used as rootstocks in pepper grafting to create pepper plants that are resistant to BPB disease. In this study, organic fertilizer was used as a nutrient enhancer in the soil; therefore, the type of organic fertilizer used was kasgot fertilizer (former maggot), which is expected to increase the nutrient content in the soil and have an influence on the growth of melada plants. The purpose of the study was to determine the effect of applying kasgot fertilizer on the growth of melada plants to increase their growth. This research will be conducted from August 16 to November 16, 2023. Research will be carried out at the Green House, Faculty of Agriculture, Tanjungpura University, Pontianak, West Kalimantan. This study uses a single-factor randomized group design (RAK) with factors in the form of applying Kasgot fertilizer. This study consists of 5 levels of treatment: K0 = Kasgot 0 g; K1 = Kasgot 20 g/1 kg alluvial soil; K2 = Kasgot 40 g/1 kg alluvial soil; K3 = Kasgot 60 g/1 kg alluvial soil; K4 = Kasgot 80 g/1 kg alluvial soil. The variables observed were an increase in shoot length, an increase in the number of leaves, root length, root volume, and plant biomass. The results of this study showed that the treatment of K3 with 60 grams of kasgot fertilizer/1 kg of soil had the best influence on the growth of melada plants.

Abstract

Melada (Piper colubrinum Link.) termasuk tumbuhan liar yang tidak dibudidayakan untuk tujuan khusus. Melada ini tahan terhadap serangan penyakit busuk batang sehingga digunakan untuk batang bawah pada penyambungan lada. Untuk mendapatkan batang bawah yang bagus perlu pemeliharaan yang baik seperti pemupukan, sehingga dapat mendukung pertumbuhannya. Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk NPK terhadap pertumbuhan bibit tanaman melada dan mendapatkan dosis optimum pupuk NPK. Penelitian ini dilaksanakan di lahan percobaan Fakultas Pertanian Universitas Tanjungpura, berlangsung dari tanggal 14 Juli-4 Oktober 2023. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Lengkap faktor tunggal dengan 5 perlakuan dan setiap percobaan diulang 4 kali. Perlakuan dosis pupuk NPK terdiri atas empat   taraf, yaitu : pupuk NPK 0 gram/tanaman, pupuk NPK 6 gram/tanaman, pupuk NPK 9 gram/tanaman, pupuk NPK 12 gram/tanaman, dan pupuk NPK 15 gram/tanaman. Variabel yang diamati dalam penelitian ini adalah pertambahan tinggi tanaman, pertambahan jumlah daun, pertambahan diameter batang, indeks warna daun, panjang daun, dan lebar daun. Hasil penelitian menunjukkan bahwa pemberian beberapa dosis pupuk NPK yang berbeda memberikan pengaruh terhadap pertambahan tinggi, panjang daun, dan lebar daun melada. Penambahan dosis tidak serta merta meningkatkan pertumbuhan. Pemberian pupuk NPK dosis 6 g/tanaman menunjukkaan dosis optimum untuk bibit melada.

Abstract

Sweet potato (Ipomoea batatas L.) is a widely cultivated crop in Indonesia, valued for its high economic potential and versatility. The Cilembu variety, originating from West Java, has been recognized for its high yield potential. This study aimed to determine the optimal harvest time for Cilembu sweet potatoes grown on PMK soil. Conducted from September 2024 to February 2025, the research employed a completely randomized design (CRD) with five treatments (harvest times: 3, 3.5, 4, 4.5, and 5 months) and four replications. Variables observed included fresh weight, dry weight, tuber weight, diameter, number of tubers, sugar content, moisture content, and fiber content. Results showed that harvest time significantly affected tuber diameter, tuber weight, and sugar content. The study concluded that harvesting at 4 months yields optimal tuber weight and diameter with standard fiber and moisture content, while the highest sugar content was achieved at 3.5 months. This research contributes to optimizing sweet potato cultivation practices, enhancing yield quality and quantity

Abstract

Screening of Ganoderma Antagonistic Fungi from Palmae Roots in Kubu Raya Regency, West Kalimantan, Indonesia. Basal stem rot (BSR) disease, caused by the pathogen Ganoderma sp., is the most important disease in palms (Arecaceae, formerly known as Palmae). To date, there is no effective method for controlling Ganoderma. In oil palms, several methods developed can only slow the rate of infection or extend the plant's productive period. Biological control is an alternative method for controlling Ganoderma and is currently under development. However, the development of biological control is hampered by its limited distribution. The most feasible approach is to identify effective indigenous antagonists from the rhizosphere of palms and develop methods for their utilization. This is because the palm family is a group of plants with high species diversity, so it is suspected that they also have a high diversity of rhizosphere fungi. Therefore, it is suspected that there are fungi antagonistic to Ganoderma that can be used as biological control agents against Ganoderma sp. This effort can be done by isolating and screening microorganisms from the rhizosphere of palm plants for their ability to act as antagonists against Ganoderma, and testing their activity in the rhizosphere of palm plants under various combinations of environmental factors thought to support their effectiveness in controlling Ganoderma. Specifically, this research aims to identify Ganoderma antagonists from the rhizosphere of palm plants in West Kalimantan that are effective in controlling BPB disease. The research has been conducted by isolating and testing the ability of fungi from the roots of palm plants in West Kalimantan in controlling Ganoderma sp. The results showed that 50.97% of fungi isolated from palm roots inhibited Ganoderma growth in vitro, with inhibition ranging from 70% to 83%. Given this ability, further testing is needed to determine the effectiveness of these fungi in controlling stem rot disease caused by Ganoderma in palm plants.
