Arrowroot tubers (Maranta Arundinace L.) are a tuber plant that has potential as a source of carbohydrates. Arrowroot tuber plants have the potential to adapt well to various environmental conditions including water stress. The aim of this research was to identify the effect of water stress on yield production (number, weight, length and diameter) and evaluate the nutritional content of arrowroot tubers. This research used a Completely Randomized Design (CRD) with 7 water stress treatments, namely (P1) 15 days of waterlogging, (P2) 10 days of waterlogging, (P3) 5 days of waterlogging, (P4) daily watering, (P5) watering every 5 days, (P6) watering every 10 days, and (P7) watering every 15 days which was repeated in 2 experimental repetitions and 2 measurement repetitions. The results of the research showed that there was no decrease in yield in treatments P1 to P3, however in treatments P6 and P7 there was a difference in the yield of lower tuber weight compared to the daily watering treatment (P4) and the once every 5 days watering treatment (P5). Treatment The results of proximate analysis of arrowroot tubers with the best yield production (P5) showed that the water, ash, fat, protein and carbohydrate content of fresh tubers were respectively 69.82%, 1.47%, 0.21%, 0, 45% and 28.15%, while arrowroot flour is 2.28%, 4.77%, 0.33%, 1.47% and 91.16%. The results of this research provide information that arrowroot plants can be planted on land that has the potential to be flooded during the arrowroot growing season, but arrowroot plants require sufficient water to optimize their production. The high carbohydrate content of arrowroot tubers reflects its potential as an alternative food source to replace wheat and rice.

Changes in land cover are thought to be the main factor in the Urban Heat Island (UHI) phenomenon. UHI is a form of local climate change which is characterized by an increase in temperature reaching 6oC in central urban areas compared to vegetated areas on the outskirts of the city. Compact vegetated land or Green Open Space (GOS), which is able to avoid increasing the surrounding temperature. GOR H. Agus Salim as one of the GOS in Padang City is a place for residents to have recreation and fill their free time by enjoying various culinary delights with friends and family as well as sports activities. This research aims to measure the benefits of tree canopies as climate amelioration in the H. Agus Salim GOR area. The research was conducted in September 2023, with 7 repetitions at 5 measurement points (3 under the tree canopy and 2 in the open field). Data is measured directly in the field with a thermohygrometer. The cooling effect provided by trees was analyzed using a difference approach between measurements in shade and open areas. Thermal comfort level is measured using the empirical formula Temperature Humidity Index (THI). The results showed that there was a decrease in temperature under the tree from 2,0oC (in the morning) to 2,9C (in the afternoon). However, THI calculations show that GOR H. Agus Salim is in the Uncomfortable criteria both under a canopy and in open areas.

Dryland soils a very high potential land for the development of agricultural crops, including vegetable crops, although the obstacles faced are due to low soil fertility, therefore efforts that can be made to increase production can use mycorrhizal biofertilizers and the use of high-yielding eggplant varieties. Hyphal elongation by mycorrhizal biofertilizer is expected to increase N, P, and K nutrient uptake, growth, and yield of green eggplant and green eggplant varieties can adapt well to less suitable environments. This research was conducted on a farmer's land on Klp Raya Road, Talang Kelapa, Alang-alang Lebar District, South Sumatra Province from March to June 2022. The research used field experiments. The experimental design used RAK Factorial with 6 treatment combinations that were repeated 4 x. Factor 1: Variety (V): Milano (V1), Ratih-Hijau-1 (V2). Factor 2: Mycorrhizal Biofertiliser (M): 5 g (M1), 10 g (M2), 15 g (M3) per plant.

The Puspa tree (Schima wallichii (D.C.) Korth.) is often used in reforestation and forest restoration activities. Puspa seed propagation techniques can be applied by generative or vegetative plant propagation. The lack of nutrients causes the availability of Puspa seeds very limited. Organic nutrients are used to obtain quality fertile plants and to accelerate growth. In this study, organic nutrients from Hydrilla plants. This study aimed to determine the best application of Hydrilla compost on the growth of Puspa seedlings. The research method used is quantitative. This study used a randomized block design (RBD) with levels of 3 treatments and nine groups, so there were 27, 3 samples were taken for each group, so there were 81 tillers. The treatments in this study were H0 (2000 grams of topsoil), H1 (2000 grams of topsoil and 200 grams of hydrilla compost), and H2 (2000 grams of topsoil and 400 grams of hydrilla compost). The method of work in this research was making hydrilla compost, preparing puspa seeds, planting puspa seeds, and caring for puspa seeds. The observed variables were growth rate (%), number of leaves (strands), plant height (cm), stem diameter (mm), and growing root length (cm). The results showed that the H2 treatment gave the best results for plant heights that were very significantly different, with an average of 8.45 cm, the number of leaves was very significantly different, with an average of 11 strands and root lengths of 4.13 mm.

Chlorophyll-a is an indicator of the abundance of phytoplankton in waters which plays a role in the process of photosynthesis. Phytoplankton plays a crucial role in determining primary productivity in waters. Organic carbon production during photosynthesis is defined as direct or net primary productivity (Net Primary Productivity). Ternate Island waters are part of the province of North Maluku and as one of the waters that play a vital role in contributing to the production of capture fisheries, especially pelagic and demersal fish. This research was carried out from January to June 2020, located in the waters of the City of Ternate. This research data was obtained by downloading the detected image/Aqua MODIS. This image data is available on the internet (http://oceancolor.gsfc.nasa.gov).

This study aims to determine the effect of treatment on increasing the brightness of the color of ornamental fish (Betta Sp) during the feeding period and the growth response of toman fish during treatment. The treatment was pumpkin extract (Cucurbita moschetta Durch) mixed into pellet feed with various combinations. The color in fish is determined by connective tissue in the epidermis, which is the availability of pigments from pellets that can be bound and absorbed by the fish’s body. This research was carried out from August to October 2022 in the Laboratorium of Aquaculture. This study is an experimental method with a completely randomized design (CRD) with each treatment as follows, 10ml/100gr,20ml/100gr, and 30ml/100gr feed for 60 days. The results showed that adding pumpkin extract of 30ml/100gr could increase the color brightness of ornamental fish. Based on the results of the variance test, it showed a significant level of significant effect.
