Abstract

Demand for the Granola variety of potatoes continues to increase, but its productivity is not yet sufficient for market needs. This is due to the wilt disease attack on potatoes caused by the fungus Fusarium sp., thereby reducing potato productivity. The aim of this research was to determine the use of liquid culture of Streptomyces sp. ASR 67 and liquid organic fertilizer as an organic anti-fungal in controlling wilt disease caused by Fusarium oxysporum on potato plants (Solanum tuberosum L.). The research was carried out using a Randomized Group Design (RAK) method using five treatments. Each treatment was repeated five times and each repetition used one potato plant. Treatment was given by watering the potato growing medium for 30 days, which was done every three days. The results showed that administration of liquid culture of Streptomyces sp. ASR 67 10% combined with liquid organic fertilizer (1:9) was able to increase plant growth with the parameters of height, number of leaves, number of stems, weight of tubers significantly, while POC 2% and Streptomyces sp. ASR67 (1:1) is able to reduce the incidence of wilt disease best.

Abstract

The study was conducted in the home garden of Tanen hamlet in Ngargoyoso, Karanganyar, Central Java, Indonesia, which is situated at an elevation of 772 meters above sea level. The existence of Sukuh Temple near Tanen with Keris reliefs shows Keris culture in this region since ancient times. This study aims to identify plant species in the Tanen home garden suitable for Keris culture and understand their potential roles in Keris culture. Sampling was carried out using the cruising method, following the village road. Data on the plants on-site were collected through surveys conducted in the home garden. The plant species were classified with the assistance of The Mountain Flora of Java and www.theplantlist.com. The plants found were determined to be related to the Keris culture. The data were qualitatively analyzed to determine the role of each plant species in Keris culture and quantitatively assessed using the species richness index. The home garden in Tanen comprises a variety of species, with a species richness of 26 belonging to 19 families. Herbs make up 38% of the plant habitus in Tanen's home garden, which also has shrubs (31%), trees (23%), and bushes (8%). The most commonly used plant organs are leaves (24%) and flowers (24%). The potency of plants in the Tanen home garden for Keris culture is: for the name of the plant called in the blade of the Keris; for warangka (sheath) and deder (hilt); for equipment in Keris making; for cleansing agents; for fragrances (fragrant agents); and offering (food ingredients, spices). The primary potential use of plants in Tanen's home garden is for offering.

Abstract

Apocynaceae merupakan salah satu famili tumbuhan tingkat tinggi yang memiliki keanekaragaman sekitar 2.000 spesies yang tersebar di daerah tropis dan subtropis. Salah satu tempat eksplorasi keanekaragaman spesies anggota famili Apocynaceae adalah di Kampus Universitas Sebelas Maret, Surakarta yang memiliki potensi sebagai pertumbuhan berbagai tanaman tingkat tinggi. Penelitian ini bertujuan untuk mengetahui keanekaragaman dan hubungan kekerabatan spesies anggota famili Apocynaceae berdasarkan karakteristik morfologi di Kampus Universitas Sebelas Maret, Surakarta. Metode penelitian yang digunakan adalah metode eksplorasi.  Sampel yang didapat kemudian diidentifikasi berdasarkan 15 ciri karakteristik morfologi menggunakan kunci determinasi Flora of Java, lalu mendeskripsikan karakter morfologi sesuai fakta di lapangan. Hasil penelitian ditemukan sembilan spesies anggota famili Apocynaceae yang terdiri dari lima genus berbeda yaitu spesies Tabernaemontana divaricata L., Tabernaemontana corymbose L., Catharanthus roseus L., Catharanthus lanceus L., Cerbera manghas L., Plumeria acuminata L., Plumeria inodora L., Plumeria alba L., dan Adenium obesum L. Analisis klaster berdasarkan parameter 15 ciri karakter morfologi yang dilakukan menggunakan metode pengelompokan UPGMA (Unweighted Pair Group Method using Arithmetic Average) menghasilkan dua klaster. Hasil analisis komponen utama karakter morfologi yang paling mempengaruhi dalam hasil pengelompokan spesies famili Apocynaceae adalah tipe percabangan, warna bunga, bentuk daun, posisi mahkota bunga, tipe perbungaan, pangkal daun, habitus, bentuk buah dan biji.
