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 highest eggplant yield was achieved by the Milano variety with mycorrhizal biofertilizer 10 g/plant produce 10.14 kg/plot or equivalent to 27.04 tonnes/ha and increased 93.88% when compared to Ratih Hijau-1 variety with mycorrhizal biofertilizer 5 g/plant.

Vegetable business opportunities, one of which is green lettuce, is still quite high. PT Amboja Global Lestari is a producer of hydroponic-based green lettuce. There is competition from green lettuce producers in Yogyakarta province and surrounding areas which significantly affects the sales level of PT Amboja Global Lestari's hydroponic green lettuce, so it is necessary to plan a strategy to be able to win the competition. The purpose of this study is to identify internal and external factors of hydroponic green lettuce marketing, analyze alternative marketing strategies, and determine the priorities of hydroponic green lettuce marketing strategies. The basic method of research uses a descriptive method with a qualitative approach. The data analysis method uses IFE Matrix, EFE Matrix, IE Matrix, SWOT Matrix, QSPM. The results of data analysis show internal factors that are the company's main strength in marketing hydroponic green lettuce, namely, quality green lettuce products, good service to consumers, guaranteed product quality guarantees to consumers, and online and offline promotions and sales are running well, with the highest score of 0.31, while for the main weakness, the distance to the hydroponic garden is quite far with the lowest score of 0.09. The main external opportunities are high consumer demand for vegetables, and there are often exhibitions with a score of 0.35, while the main threats are, the increase in new competitors, effective competitor marketing online and offline, and disease and fungal attacks, with a score of 0.21. IE Matrix Analysis shows that the company is in a position to grow and develop. The SWOT Matrix Analysis resulted in six alternative marketing strategies. QSPM analysis resulted in the main strategy priority of hydroponic green lettuce marketing, namely, increasing the quality and quantity of hydroponic green lettuce with a total TAS value of 7,615.

This study aims to determine the effect of mulching on the growth and production of chili plants. This study used a randomized block design, with 6 treatments and 4 replications. One treatment 4 sample plants. The treatments used are as follows: M0: Without using mulch; M1= Using reed mulch; M2 = Using rice straw mulch; M3 = Use silver black plastic mulch; M4 = Using clear plastic mulch; M5 = Use clear mulch covered with newspaper. The variables observed were plant height, number of secondary branches, fruit weight per plant, dry plant weight and production per hectare. Based on the results of the research that has been carried out, it was concluded that: black silver plastic mulch treatment gave the best effect on the growth and production of chili plants, such as plant height, number of secondary branches, fruit weight of each plant, dry weight of plant trunks, and production per hectare. Meanwhile, the production of red chilies per hectare produced by silver black plastic mulch has a higher capacity of 8.02 tons/ha and the lowest yield is 3.01 tons/ha of clear plastic mulch.

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).

In the fish farming business, feed is the highest operational cost, which reaches more than 60% of the total production cost. Therefore, the fish feed can be processed independently to reduce production costs in aquaculture businesses. This study aimed to determine the survival rate and feed efficiency of red tilapia (Oreochromis sp) fed artificial feed with the addition of seaweed (Gracilaria sp). This research was carried out from June to September 2021 at the Integrated Laboratory of Khairun University. This study used four treatments, and each treatment was repeated three times. The treatment tried is A (Artificial feed with the addition of Gracilaria sp 10 gr); B (Artificial feed with the addition of Gracilaria sp 20 gr; C (Artificial feed with the addition of Gracilaria sp 30 gr); and D (Artificial feed without the addition of Gracilaria sp.). The research variables included calculating the survival rate (SR), Feed Conversion Ratio (FCR), and observing water quality during the study. The highest survival value was in treatment B at 97.78%, while the lowest was in treatment A at 73.33%. The highest feed conversion ratio was in treatment D, 1.97, followed by treatments A and B, 1.48, and the lowest in treatment C, 0.64. The results of water quality measurements during the study, namely DO, range from 6-6.8 in all treatments, pH ranged from 7-7.6, and temperature ranged from 28-290C. The best survival rate (SR) of red tilapia-fed artificial feed with the addition of Gracilaria sp seaweed was best in treatment B, 97.78%, and the best feed conversion ratio (FCR) was in treatment C, which was 0.64 g.

Dried fish is a processing fishery product carried out traditionally and simply with the help of sunlight. This fish processing is carried out to add value to fish and fishery products. This study aims to analyze the amount of added value of the dried fish-making business in Bengkulu City. This research was conducted from January to February 2022 in Sumber Jaya Village, Kampung Melayu District, Bengkulu City. The sample of this study was 86 people selected using the census method, where the entire population was sampled. The data used are primary and secondary, and the data analysis used is a quantitative analysis using the Hayami method. The results showed that the business of making dried fish in Bengkulu City could create added value because it had an NT value of >0 (positive).
