This study aims to identify and determine the viability and vigor of seeds of some species of plants in Ambon city market. This research was conducted in the Laboratory of Seed Control and Certification Institute (BPSB) Passo and at the Faculty of Agriculture, University of Pattimura Greenhouse Ambon from February to April 2012. The method used was testing seed with duplo system and using T test with three replications. There were eight seed plant types tested, i.e corn, mustard, long bean, eggplant, bitter melon, cucumber, large chili, and cabbage. Responses observed consisted of viability parameters, i.e. germination percentage, germination rate, and germination rate index, and vigor parameters consisted of simultaneity sprouted seeds and sprouted seeds pace. The results showed that seeds in the market city of Ambon, such as corn, mustard, long beans, eggplant, bitter melon, cucumber, large chili, and cabbage were in excellent quality, as shown by the results of the seed germination rate which reached 90.33 - 97.33% at laboratory test, meanwhile at greenhouse test the rate reached 90.33 - 94.33%, strong vigor with synchrony seed grow were 51.00 - 64.67%, and the growth rate reached 29.46 - 33.65%.
Green seaweed Caulerpa sp is found in several coastal waters in Indonesia and is used as fresh vegetables by people in the growing habitat area. This study aimed to conduct a review of the potential of Caulerpa sp as functional food. The development of this paper is a literature review of relevant writings to determine the position of sea grapes Caulerpa sp as functional food. Data and relevant information are displayed in the form of figures and tables. Caulerpa seaweed grows naturally and is available throughout the year. Caulerpa contains crude fiber and secondary metabolites which positions Caulerpa as a functional food ingredient. The components of superior nutrition in Caulerpa are minerals, proteins, fats, and carbohydrates. The superiority of Caulerpa as a food ingredient is its processing which is very simple and brief and does not require food additives in the form of dyes and essences.
Nutmeg (Myristica fragrans H) is native to Indonesia, which has been known as herbal plants. Its planting areas, however, are often hindered by the presence of unwanted plants. Weeds are among the plant pest organisms (PPO), which inhibit the growth, development and productivity of crops. Identification of dominant weed species is the first step in determining the success of weed control. This research was conducted in Hutumury Village, Ambon, with an aim to determine weed species composition and dominant weed species in producing and non producing (juvenile) nutmeg plantations. The process of data collection in the field was undertaken by a survey method. The results showed 18 weed species were found in the plantation of non producing phase and 13 weed species were found in the plantation of producing phase. In the producing plantation, the dominant weed species was Selaginella plana Heron with an SDR value of 57.80%. In the non producing plantation, the dominant weed was also Selaginella plana Heron with an SDR value of 44.42%. The overall dominant weeds in the nutmeg plantations belonged to the annual broad leaf weeds.
The purpose of this study was to analyze the types of dominant weeds in rubber plantation areas at altitudes of 4 m above sea level (asl) and 104 m asl and to find differences in the types of weeds in the rubber plantation areas at an altitude of 4 m asl and 104 m asl. This research conducted in Negeri Liang, Teluk Elpaputih District, Central Maluku Regency. This research used a "weed survey" method to collect data by direct observation in the field. This research was conducted by analyzing weed types using the quadratic method by purposive sampling with a sample plot size of 1 m × 1 m. From this study, it was found that there were 20 weed species from 14 families, with details of 11 species of full leaf weeds, 3 species of grasses, 3 species of sedges, in rubber plantation habitat in Liang Village, Teluk Elpaputih District, Central Maluku Regency. Keywords: plantation altitude, rubber plants, weeds ABSTRAK Tujuan penelitian ini adalah untuk menganalisis jenis-jenis gulma dominan di areal perkebunan karet pada ketinggian 4 m dpl dan 104 m dpl dan untuk menemukan perbedaan jenis-jenis gulma di areal perkebunan karet pada ketinggian 4 m dpl dan 104 m dpl. Penelitian ini dilaksanakan di Negeri Liang Kecamatan Teluk Elpaputih Kabupaten Maluku Tengah. Dengan menggunakan metode “survey gulma” untuk mengumpulkan data dengan pengamatan langsung di lapangan. Dengan melakukan analisis jenis gulma digunakan metode kuadrat secara purposive sampling dengan petak sampel berukuran 1 m × 1 m. Penelitian ini di peroleh terdapat 20 jenis gulma 14 famili, dengan rincian gulma daun lebar 11 jenis, rerumputan 3 jenis, tekian 3 jenis, dan pakisan 3 jenis pada habitat perkebunan karet di Negeri Liang Kecamatan Teluk Elpaputih Kabupaten Maluku Tengah. Kata kunci: gulma, ketinggian tempat yang berbeda, tanaman karet
The decline of mustard (Brassica juncea L.) production can indicate a plant nutrition problem. The purpose of this pot experiment was to determine the response of green mustard to the application of NPK and Chitosan fertilizers which were applied at the same time. The experimental design completely randomized design with three replications and two factors, namely NPK fertilizer with five levels of dosage, namely 0.0 g/plant, 0.4 g/plant, 0.8 g/plant, 1.2 g/plant, and 1.6 g/plant, and Chitosan with four levels of concentration, namely: 0%, 10%, 20% and 30%. Observed variables were plant height, number of leaves, average leaf area, total leaf area, root length, root fresh weight, stem diameter, and plant fresh weight. The results of the study found that the use of NPK and Chitosan fertilizers increased plant growth indicated by plant height, number of leaves, leaf area and root length, as well as plant yield indicated by plant fresh weight. There was no interaction effect between the two treatments but independently both treatments have a positive effect on growth and yield of green mustard. The higher the dose of NPK fertilizer and the concentration of chitosan will increase the effect. The best treatment composition recommended for green mustard cultivation was NPK fertilizer with a dose of 1.6 g/plant and chitosan with a concentration of 20%.
