Abstract

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%.

Abstract

Nutmeg (Myristica fragans Houtt) is one of the plantation crops that has high economic value in addition to cloves, rubber, coffee, tea and cocoa. To get good plant growth, quality seeds are needed and to get good seeds, sufficient nutrients are needed for the growth of roots, stems and leaves. Planting media in nurseries must be of good quality so that the seeds produced are also of good quality, one of the quality planting media is using sago ela compost and using young coconut water as a growth regulator. This study aims to obtain the optimal dose of sago ella compost and young coconut water concentration on the growth of nutmeg seedlings in nurseries. The treatments used sago ella at a dose of 300 g/pot and 600 g/pot), and young coconut water with concentrations of 0%, 25% and 50%. The results showed that the sago ella treatment had a significant effect on the variables of plant height, leaf number and root length, but had no effect on stem diameter and root crown ratio, while young coconut water treatment had an effect on seedling height and number of leaves, but had no effect on root length. , stem diameter and crown to root ratio. The real interaction was only on plant height

Abstract

"Dusung" is a habitat with a variety of plant communities in the form of trees. bushes, and grass. Research aims to identify under growth in "Dusung" at different altitudes. The research was carried out in Dusung Hative Besar using the method of surveying weeds directly in the field. Vegetation analysis using the squared method by purposive sampling with sample plots measuring 1×1m. Sampling on nutmeg plantation areas is carried out in each area at various different heights, namely at altitudes of 0, 100, and 200 m asl. The results showed that the value of the community coefficient (C) obtained from the comparison between two communities, namely between 0 and 100 m asl, was 0%, while 0 and 200 m above sea level was3.17%. This shows that the lower plant communities at an altitude of 0 and 100 m above sea level and 0 and 200 m above sea level are different because of the value of C<70%. While the comparison between two communities altitudes of 100 and 200 asl has a C value of 72.48% means that the lower plant community between the two heights of the place being compared is the same or uniform (C >70%).

Abstract

This study analyzes public knowledge regarding household waste management in Batu Gajah Subdistrict, Sirimau District, Ambon City. In the context of increasing household waste volume due to population growth and economic activities, this study aims to assess the public's understanding of the importance of waste separation and recycling. A descriptive research method was used, with a sample representing 10% of the total population randomly selected from heads of households in each neighborhood unit (RT). Data were collected through observations, questionnaires, and interviews and analyzed using Miles and Huberman's interactive model. The results indicate that most respondents understand the difference between organic and non-organic waste, but knowledge of plastic recycling techniques and composting still needs to be improved. Additionally, most of the community is aware of the negative environmental impacts of burning waste, although practices related to electronic waste management remain minimal. This study highlights the need to improve education and public participation in waste management through collaboration between local governments and communities.

Abstract

This study aims to compare the methods of testing the moisture reduction of cocoa beans with the high-temperature and low-temperature oven methods. The method used in this study was a comparative test between three cocoa clones and two moisture content test methods, namely using a low-temperature oven and a high-temperature oven. This research is experimental using a completely randomized design (CRD). The results of the cocoa moisture content test showed that each treatment of K2O2 and K1O2 was not significantly different from the results of the moisture content of cocoa beans. In contrast, the comparison of each treatment of K2O2, K1O2 and K3O2 was significantly different from the results of the moisture content of cocoa. Furthermore, for the K3O2 treatment compared to each of the K1O1, K2O1, and K3O1 treatments, the results of cocoa content were significantly different. For each treatment, K1O1, K2O1, and K3O1 did not differ significantly in the results of the moisture content of cocoa. High temperatures and low temperatures in Table 2 show that the K1O1 yield is 8.03%, significantly different from the K1O2 cocoa bean moisture content, which is 9.59%. and K3O1 7.57% with K3O2 which is 8.85 Testing the moisture content of cocoa seeds using the high-temperature oven method for 2 hours was significantly different from the low-temperature oven method for 17 hours. The proper method for testing the moisture content of cocoa beans is high temperature for 2 hours.
