“…grows on the type of loamy sand texture [22]. Water temperature is directly affected the plant growth, and temperature is related to the light which is one of the environmental factors and play an important role in plant growth through photosynthesis [23]. Moreover, temperature is one of environmental parameters as controlling factor for seedling growth, because it was related to photosyntethic of mangrovevegetation [37].…”

Ecosystem mangrove is an important ecosystem both ecologically and economically. Therefore, this ecosystem needs to be managed in a sustainable manner. Mangrove rehabilitation is one of the activities to reduce the rate of destruction of mangrove forests and it is a conservation effort on damaged mangrove land. The purposes of the research were to analyse the rate growth of seedling Rhizophora sp. after rehabilitation, and the correlation between environmental parameters and seedling growth in mangrove rehabilitation, Aceh Besar and Banda Aceh. The observation was started from January to March 2022. The results obtained are important data in planning sustainable mangrove forest management. The highest increasing in stem height and stem diameter of Rhizophora sp. were at stations one with values of 1.22 cm week−1 and 0.25 mm week−1. All sampling location showed the number of leaves was increased 1 leave week−1. The highest increasing of stem height at the fourth week with the value were 2.1 cm week−1 in station 1, and 2.2 cm week−1 for station 2. The pearson correlation explained that there was no significantly correlation between environmental characteristics included C-organic, soil fraction, nitrogen (N total), potassium (K), dissolved oxygen (DO), pH and temperature with seedlings growth of Rhizophora sp where Psig.>0.05. However, the soil profile consisted of Phosphorous (P) and salinity was significantly correlation with seedling growth due to Psig. <0.05.

Eucalyptus oil is a superior regional commodity in Buru Regency. In addition to the relatively high selling price, oil derived from the eucalyptus plant is needed by various industrial sectors to be used as an essential ingredient for medicine. However, when we examine the daily lives of eucalyptus oil farmers, we will find that the economic situation is quite worrying, and the socio-economic environment lags behind the workers in other sectors. If natural resources are abundant, eucalyptus oil workers should be able to have a decent life, especially amid the Covid-19 pandemic, which severely limits the social and economic space of workers. This study uses a phenomenological approach, the determination of informants using a purposive sampling technique based on predetermined criteria and determined based on the research objectives. Field findings show that farmers use physical adaptation strategies to meet production targets, negatively impacting labor and land sustainability. Excessive time and work patterns result in the emergence of physical insecurity among farmers, as well as land degradation, which endangers the survival of farmers. We propose that intensive and constant rehabilitation of production can reduce the detrimental impact of the physical approach of eucalyptus oil farmers during the pandemic, ensuring the sustainability of farmers and land.Keywords: Adaptation; Land, Farmers; Strategy

“…On potato plants grown in Vertisol treated with N and P fertilizers, significantly increased the growth and yield (Zelalem et al 2009;Putra, Saparso, Rohadi, et al 2019). While the process of translocation in plants is inseparable from the role of potassium (K) because, in a case of K deficiency in the soil and the plant tissue, it will interfere with the absorption of other elements such as N, P and assimilates translocation from source to sink (Kanai et al 2011;Jati et al 2017). Physiological components affecting seed yield of soybean The relationship is shown by physiological variables that affect the yield and yield components, i.e., the number of pods plant -1 , the number of seed plant -1 and seed weight (g plant -1 ) and seed yield (t ha -1 ) are affected by photosynthetic rate and P content in tissues (Table 3).…”

Fertilization of N, P, and K on soybean planted under Kayu Putih stands to serve to increase soil nutrients. Lithic Haplustert is a subgroup of Vertisol with a relatively low fertility and organic matter with a heavy clay texture. This research aims to determine the response of soybean to the application of N, P, and K fertilizers on the Lithic Haplustert in physiology and yield. This research was conducted from February to May 2015 in the Srikoyo hamlet, Menggoran village, Playen district, Gunungkidul regency, Yogyakarta. The experimental design is split-split plot with three levels of fertilization of N (0, 25, 50 kg urea ha-1), P (0, 150, 300 kg SP-36 ha-1), and K (0, 75, 150 kg KCl ha-1). The results showed that the application of 50 kg urea ha-1 and 300 kg SP-36 ha-1 can increase the leaf area and photosynthesis rate. Dosage 150 kg KCl ha-1 fertilizer increased the concentration of N, P, and K in the plant tissues significantly.
