The Effect of Compost Durian Peel and Organic NPK on the Production of Bitter Gourd (Momordica charantia L)”. The purpose of this study was to determine the interaction effect as well as the main effect of durian rind compost and organic NPK on bitter melon production. The research was carried out on the agricultural land of the Food Crops Seed Center, Kuantan Singingi Regency, Jalan Perintis Kemerdekaan KM 2, Pulau Godang Village, Kuantan Tengah District, Kuantan Singingi Regency. The study was conducted for 4 months, from December to March 2023. This study used a factorial Completely Randomized Design consisting of 2 factors, namely the first factor of durian peel compost (K) consisting of 4 treatment levels, namely 0, 1, 2 and 3 kg per plot. The second factor was the dose of Organic NPK (N) which consisted of 4 treatment levels, namely 0, 5, 10 and 15 gram plants. Parameters observed were flowering age, harvesting age, number of fruit per plant, fruit weight per plant, fruit weight per fruit, largest fruit diameter, longest fruit length and number of remaining fruit. Observational data were analyzed statistically and continued with the BNJ test at the 5% level. The results showed that the interaction of durian rind compost and Organic NPK significantly affected the parameters of flowering age, harvesting age, number of fruits per plant, fruit weight per plant, fruit weight per fruit and longest fruit length. The best treatment was a dose of 3 kg of durian peel compost per plot and 15 grams of organic NPK per plant. The main effect of real durian peel compost on all observation parameters. The best treatment is durian peel compost at a dose of 3 kg per plot. The main effect of real organic NPK on all observation parameters. The best treatment is Organic NPK with a dose of 15 grams per plant.

The need for orchids is increasing and the orchids are threatened with extinction due to forest exploitation and need to be supported by the provision of seeds using tissue culture technology. The research entitled regeneration of the pigeon orchid (Dendrobium crumenatum Swartz) aim of this study was to determine the effect of the interaction between the concentrations of growth regulators zeatin and sucrose on the growth of Dendrobium crumenatum Swartz callus in vitro. The experimental design used was a factorial randomized block design consisting of 2 factors. The first factor is the zeatin dose consisting of without treatment, 0.1, 1.0, and 10 ppm. The second factor is the sucrose dose consisting without treatment, 20, 40, and 60 g/l, there are 16 treatment combinations and 3 repetitions so that 48 experimental units were obtained. Each experimental unit consisted of 4 explants, so that a total of 192 explants were explants. The parameters observed were as follows: percentage of live explants, percentage of rooted explants, percentage of explants that formed callus, number of shoots, number of leaves, and chlorophyll content Follow-up test Honest Significant Difference (HSD) at 5% level. The interaction of zeatin and sucrose affects the survival percentage of explants and callus, the number of shoots and the number of leaves. The best treatment was 1.0 ppm zeatin and 40 g/l sucrose. The main effect of the best zeatin concentration is 1.0 ppm and the best dose concentration is sucrose 40 g/l.

The research of "the effectiveness of test of antifungal pineapple peel extract against seed-borne fungus and the growth of red chili (Capsicum annum L.) seedlings". The research aimed to determine the effect of pineapple peel extract as antifungal in controlling red chili seed- borne fungus and its effect on germination and growth of red chili seeds. The recent research was carried out using a completely randomized design non factorial consisting of 5 treatments and 5 replications. The treatment factor is concentration of pineapple peel extract consisting of without pineapple peel extract, pineapple peel extract of 10%, 20%, 30%, and 40% respectivelly. The results showed that the appropriation of several concentrations of pineapple peel extract was less effective in controlling red chili seed-borne fungi in vitro, which can be seen in the results of the observed parameters for the incidence of each pathogenic fungus in seeds and the diameter of the seed colonies. The appropriation of several concentrations of pineapple peel extract has an effect on the germination of red chili seeds in vitro, which can be seen from the results of the observation parameters that sprouts appear, but have not affected the parameters of the observation of seed germination. The appropriation of several concentrations of pineapple peel extract affected the growth of red chili seedlings in soil media, which can be seen from the results of the observation parameters of the percentage of germinated seeds, and the number of live seeds and seedlings that grew normally, but had no effect on the parameters of observation of seedling height, number of leaves seeds, plant wet weight and plant dry weight).

Research entitled The Effect of Colchicine Concentration on the Growth and Production of Black Soybean Plants of the Detam 2 Variety (Glycine soja (L) Merr). The aim of this research was to determine the concentration of LD47, as well as the effect of colchicine concentration on the growth and yield of black soybean plants of the Detam 2 variety (Glycine soja (L) Merr). The research was carried out at the Air Dingin experimental garden, Faculty of Agriculture, Universitas Islam Riau. The research period was carried out for six months from January to June 2023. The research carried out consisted of II stages. Phase I research was to determine the concentration of colchicine LD47 (Lethal Dose 47%). The treatment concentrations are: K0= 0 ppm, K1= 500 ppm, K2= 1000 ppm, K3= 500 ppm, K4= 2000 ppm, K5= 2500 ppm, K6= 3000 ppm, K7= 3500 ppm. Phase II research was carried out by inducing colchicine mutations using control and LD47. Phase II research was carried out to determine the effect on growth and production in control and treatment samples that had been mutated with LD47 concentrations. Phase I research showed the sensitivity of black soybean plants with a survival percentage of 47%. It can be seen that the LD50 concentration obtained was 3599 ppm and the concentration used for phase II was LD47 colchicine concentration of 3500 ppm. The effect of colchicine LD47 had a significant effect on the parameters of petiole length, number of branches, widest leaf area, stem diameter, flowering age, number of pods per plant and dry seed weight per plant. The effect of colchicine LD47 had no significant effect on the parameters of plant height, node or node length, percentage of pithy pods, fruit stalk length and weight of 100 dry seeds.

The research entitled identification the phenotypic variance of qualitative and quantitative characters of oil palm (Elaeis guineensis Jacq.) origin of Angola. The objective of the study was to determine the specific characteristics of the oil palm population of dura and tenera Angolan germplasm on phenotypical characterization whether qualitatively and quantitatively as well. The research was conducted in seeds garden of the oil palm seeds company in Siak Hulu of Kampar District. The genetic material used in this study was oil palm germplasm as much as 1996 oil palms in 15.50 hectars. The Angola accession population consisted of 80 Dura accessions with 1,309 oil palms and 26 Tenera Accessions with 687 oil palms. The analytical method used is the Coefficient of Phenotypic Variation (KKF) and Principal Component Analysis (PCA). The results show that the main component of the quantitative variable can explain the variation of the Angolan oil palm population by 79.76% with parameters such as oil to bunch (%), oil to fruit (%), dry mesocarpto fruit (%), relative leaf area (m²), wet mesocarp to fruit, frond length, palm height, number of leaves, periole width (cm), and petiole cross-section (cm²). The proportion of low KKF with a high O/B average is found in AGO001, AGO086, AGO101, and AGO 106.
