Abstract

Jamblang merupakan salah satu buah lokal Indonesia yang keberadaannya sudah jarang ditemukan. Jamblang dikenal oleh masyarakat Sumatera Barat khususnya Kota Padang sebagai jambu kaliang. Polen merupakan organ generative jantan dari tanaman yang berfungsi sebagai sarana utama pengalir gen pada persilangan spesies. Fertilitas adalah kemampuan polen atau bakal buah untuk tumbuh normal membentuk benih. Sedangkan sterilitas adalah kegagalan proses pembuahan karena ketidakmampuan pollen atau bakal buah untuk membentuk biji. Viabilitas polen merupakan persentasi polen yang akan menyelesaikan perkecambahan dan membentuk tabung sari (pollen tube). Penelitian ini bertujuan untuk mengatahui persentase polen tanaman jamblang yang fertile dan viable yang berguna bagi kegiatan pemuliaan tanaman. Pelaksanaan penelitian dilakukan dengan menggunakan metode pewrnaan dengan larutan bromothymol blue untuk mengamati fertilitas polen, dan pengujian vibilitas polen dengan metode Brewbaker dan Kwack (1964). Berdasarkan hasil pengamatan diketahui bahwa terdapat polen yang fertile pada semua genotype tanaman, akan tetapi tidak ada satupun polen yang mampu untuk berkecambah secara in vitro.

Abstract

Fertilization is one of the efforts to increase shallot yields in cultivation techniques. One of the organic materials that can improve soil fertility and support the growth of shallot plants is cow manure and natural ZPT from coconut water. Several studies have been conducted regarding the effect of giving doses of cow manure or coconut water concentration on shallot plants. However, there is no appropriate dose or concentration to increase the growth of shallot plants. This research was carried out using an experimental method with 2 treatment factors, the first was the dose of cow manure with 3 treatment levels, namely 10, 20 and 30 tonnes/ha. The second is the concentration of ZPT in coconut water with 3 treatment levels, namely 25%, 50% and 75%. The observational variables measured in this study are plant height, total chlotophyll, number of leaves, and number of saplings. Key-words: chlorophyll, coconut water, cow manure, cytokinins INTISARIPemupukan merupakan salah satu upaya dalam peningkatan hasil bawang merah dalam teknik budidaya. Salah satu bahan organik yang dapat memperbaiki kesuburan tanah serta menyokong pertumbuhan tanaman bawang merah adalah pupuk kandang sapi dan ZPT alami dari air kelapa. Beberapa penelitian telah dilakukan mengenai pengaruh pemberian dosis pupuk kandang sapi atau konsentrasi air kelapa pada tanaman bawang merah. Namun, belum ada dosis maupun konsentrasi yang tepat untuk meningkatkan pertumbuhan tanaman bawang merah. Penelitian ini dilakukan dengan metode eksperimental dengan 2 faktor perlakuan, faktor pertama dosis pupuk kandang sapi dengan 3 taraf perlakuan yaitu 10,20, dan 30 ton/ha. Faktor kedua konsentrasi ZPT air kelapa dengan 3 taraf perlakuan yaitu 25%, 50%, dan 75%. Variabel pengamatan yang diukur pada penelitian ini ialah tinggi tanaman, klorofil total, jumlah daun dan jumlah anakan. Kata kunci: klorofil, air kelapa, pupuk kandang sapi, sitokinin

Abstract

Both oil palm plantations boerdering forests and oil palm plantations bordering rubber plantations were studied using purposive random sampling with pit fall traps, sweep nets and yellow pan traps. Species biodiversity was analyzed using the Shanon-Wienner index and the Simpson index. The dominant species was determined using the Important Value Index. This study found 1,683 individuals, 7 orders and 18 families of predatory and parasitoid insects. The Shanon-Wienner diversity index was 2.78 for oil palm plantations adjacent to forest and 2.62 for oil palm plantations adjacent to rubber plantations. While the Simpson diversity index was 1.00 for oil palm plantations adjacent to forest and 0.94 for oil palm plantations adjacent to rubber plantations. The Order Hymenoptera Family Formicidae had the highest Important Value Index (0.58 for oil palm plantations bordering forest and 0.62 for oil palm plantations adjacent to rubber plantations).

Abstract

Agarwood oil, derived from the fragrant resinous wood of the Aquilaria and Gyrinops trees, has attracted great attention due to its diverse pharmacological properties and commercial value. The complex chemical composition of agarwood oil, consisting of more than 150 chemical compounds, has been linked to its therapeutic potential in treating chronic inflammatory diseases, anxiety, depression, and insomnia. This research uses exploratory, descriptive research. The research used in this research is the literature study method regarding the development of agarwood oil research and its benefits. Documents from the Scopus website are saved in the following form: RIS-type files. Analysis was conducted using VOSviewer 1.6.18 for Windows software. The research results show that there has been a decline in the trend of research on agarwood oil over the last 10 years; most research on agarwood oil has been carried out by Malaysia and China and followed by Japan. Research has revealed numerous benefits of agarwood oil, indicating its potential for development into derivative goods, particularly in the health and fragrance industries.

Abstract

Shallots are a high-value horticultural commodity. But so far, they have been mostly developed in the highlands. Shallots are plants that like areas with hotter air temperatures, so they are suitable for cultivation in the lowlands. Still, the soil that is widely available in the lowlands of the city of Padang is Ultisol. Ultisol contains high clay, so the soil becomes dense, the available nutrients are low, and the ground has difficulty passing water. Using Ultisol as a land for planting shallots, it requires using organic fertilizer in large doses. One of the agricultural waste products that is available and has yet to be widely used in Lambung Bukik Village is rice straw. Rice straw is a waste that is difficult to decompose. Therefore, it is necessary to use a decomposer to get compost faster. Training on making rice straw compost and making demonstration plots was carried out in Lambung Bukik, Padang City, to support the development of shallot cultivation on lowland Ultisol. Farmers are very enthusiastic about learning to cultivate shallots and making organic fertilizer from rice straw.
