This study aims to evaluate the effect of the addition of growth hormone (rGH) and spirulina flour on the performance of absolute weight growth, survival, feed efficiency, and feed conversion ratio (FCR) of cupang fish (Betta spp.). This study used a completely randomized design (CRD) with four treatments with three replications, i.e., A) Dose of growth hormone 1.5 mg+3 g spirulina flour; B) Dose of growth hormone 2 mg+3g spirulina flour; C) Dose of growth hormone 2.5+3 g spirulina flour; D) Control (no treatment). The results showed that the addition of growth hormone (rGH) and spirulina to commercial feed affected absolute weight growth of 2.27 ± 0.90 g. The survival rate was 75.00±1.11 %, the feed efficiency value was 28.98±1.17 %, and the feed conversion ratio was 1.11±0.022. The highest color intensity was found in treatment C with a score of 6.

Peanuts are a potential agricultural commodity after soybeans. Peanut production increased after 2017 but in 2018 it decreased. This occurs due to several obstacles, especially poor soil conditions, especially in several areas in South Sumatra. One effort to increase production is done by fertilizing according to the conditions and correct seed management. This research was carried out to determine the length of soaking of seeds in liquid biological fertilizer and giving different doses of phosphate fertilizer to peanuts, which was carried out from July to October 2020 in Pulau Semambu Ogan Ilir Village, South Sumatra. The experiment was carried out using a factorial randomized block design with 2 treatment factors, namely the length of immersion (0. 15 and 30 minutes) and the administration of a dose of phosphate fertilizer (50,75,100 and 125 kg / ha). The treatment of soaking seeds for 30 minutes gave the best results on the variables of the number of pods planted, the number of empty pods planted, the weight of the planted pods, the weight of the pods per plot, and the weight of 100 seeds. Treatment of phosphate fertilizer dose of 100 kg / ha gave the best results on the variables of number of pods planted, weight of planted pods, weight of pods per plot and weight of 100 seeds. The interaction between the duration of soaking the seeds for 30 minutes with a dose of phosphate fertilizer of 100 kg / ha by tabulation gave the highest yield of 1.28 kg / plot or equivalent to 3.41 tons / ha.

Medicinal plants are included in the Non-Timber Forest Products group, which has a variety of benefits, especially for human life and high economic value. Its existence is abundant in one of the customary forests in Riau Province, Ghimbo Pomuan Customary Forest. For the preservation and planning of medicinal plant management activities, it is necessary to analyze the spatial distribution of medicinal plants and determine the relationship between accessibility factors and the presence of medicinal plants. This research aims to analyzed the spatial distribution pattern of medicinal plants, map the distribution of medicinal plants, and determine the factors that affect spatial distribution based on accessibility factors. This research was conducted between March and November 2023. This study found that Ghimbo Pomuan customary forest has 24 species of plants with a total of 324 medicinal plants.The seven medicinal plants with the highest number are kacip fatimah (Labisia pothoina) 106 individuals, mempening (Lithocarpus spp) 50 individuals, matoa (Pometia pinnata) 34 individuals, pasak bumi (Eurycoma longifolia) 32 individuals, binahong (Andredera cordifolia) 30 individuals, keladi tikus (Typhonium flagelliforme) 19 individuals and bintangur (Clophyllum soulatri) 9 individuals. The spatial distribution pattern of medicinal plants is clustered with the nearest neighbor index NNI 0.58. The most influencing factor is the distance from the river, which is then followed by the distance from the road and the distance from the settlement. The farther from the river, the number of medicinal plants tends to increase, the closer the distance from roads and settlements, the number of medicinal plants increases.

The high market demand for gourami has led to an increase in fish farming activities. However, this fish farming activity is constrained by the spawning and breeding process. Gourami fish takes quite a long time in the seed growth phase so it is feared that it can hamper the fulfillment of gourami fish stocks in the market. Several studies have been conducted to shorten the growth time of fish seeds. One of them is in the field of feed. Modification and alternative feed are expected to contribute to science in the cultivation of gourami fish seeds. The purpose of this study was to determine the effect of feeding additives to increase the growth of carp fry (Osphoronemous gouramy). The research was conducted from August to October 2019 using nets in concrete ponds. The research was conducted experimentally using the group randomized design (RAK) method carried out in 4 treatments and 4 groups. The treatments tested were the provision of additional ingredients consisting of P_1 = 15% Probiotic / Kg feed, P_2 = 0.4% Vitamin C / Kg feed, P_3 = 3% Spirulina/kg feed, P_4 = 3.25% Papain enzyme/kg feed. Observation parameters include absolute length growth, absolute weight growth, survival, and feed conversion ratio. The results showed that 3% spirulina/kg and 3.25% papain enzyme/kg had a significant effect on the rate of weight growth and growth.

The decline in the amount of pepper production in Bangka Belitung was caused by the decline in the selling price of white pepper received by farmers. Apart from the decline in the selling price of white pepper, the development of other plantation commodities also influences farmers' behavior in cultivating white pepper, so that many pepper farmers choose to switch to farming other commodities. The aims of this research are 1) to describe farmers' behavior in cultivating white pepper in Delas Village, Airgegas District, South Bangka Regency, and 2) to analyze the factors that influence farmers' decisions in cultivating white pepper in Delas Village, Airgegas District, South Bangka Regency. . This research was conducted using a survey method. Sampling used purportive sampling with a sample size of 80 respondents. Data were analyzed using quantitative descriptive and binary logistic regression. The results of the research show that the behavior of farmers in cultivating white pepper in Delas Village with a percentage of 30 percent is still cultivating pepper even though the price of white pepper is low for the reason that it has been a culture passed down from generation to generation and so that the availability of pepper remains even in smaller quantities. Meanwhile, 70 percent of farmers chose to change their pepper farming to other commodities such as palm oil and rubber. The factors that influence farmers' decisions in cultivating white pepper are the variables Number of Dependents and other sources of income.
