Low productivity of para rubber trees in Indonesia can be anticipated by the application of technology in the downstream sector, especially in terms of tapping such as by the application of latex stimulants. The objectives of this study were to determine the effect of alternative stimulants sourced from household waste such as climacteric fruit peels that is mangosteen peel extract and obtain its concentration that gives the best effect on the latex production of rubber plants (Hevea brasiliensis Muell. Arg.). The reserach was carried out for five months at a smallholder rubber plantation in Dharmasraya District, West Sumatra. This study was designed using Randomized Block Design (RBD) that was repeated four times. The treatments were: without stimulant, mangosteen peel extract 3 ml application-1, mangosteen peel extract 4 ml application-1, mangosteen peel extract 5 ml application-1, and mangosteen peel extract 6 ml application-1. The results showed that the application of mangosteen peel extract as latex stimulants was able to increase the latex production when compared to without stimulant. Its application at 5 ml application-1 was able to produce the highest latex volume of 151,04 ml tapping-1 and without symptoms of tapping panel dryness.

Coffee rind compost is generated from coffee industry waste which contains enough nutrients and can be used as a mixture of planting media for supporting the growth of plant seedlings.The growth of rubber tree seedlings can be increased by applying compost as a mixture of planting media that can improve soil physical, chemical and biological properties. The objective of this study was to obtain the best dose of coffee rind compost to support the growth of rubber seedlings. The research was conducted in the experimental field of 3rd Campus Andalas University where located in Sungai Kambut Village, Pulau Punjung Sub-district, Dharmasraya District, from September 2019 to March 2020. An experiment was designed by a Completely Randomized Design (CRD) consisted of 5 treatments and 4 replications. The observed variables were shoot height, number of leaves, stem diameter and shoot root ratio. Observed data’s were analyzed by the F test at 5% level, if the F count more than the F table then it is followed by Duncan's New Multiple Range Test (DNMRT) at 5% level significantly. The results showed that the best dose of coffee rind compost to support the growth of plant height, number of leaves, stem diameter and the shoot root ratio of rubber seedlings was 400 g / polybag.

Crickets feces manure is the solid waste produced by cricket metabolism which contains some nutrients. Its application as the mix of planting medium is very potential for increasing plant growth. The objectives of this study were to determine the effect of several doses of crickets feces manure on the growth of cacao (Theobroma cacao L.) seedling and to obtain the best dose of it for growth of cacao seedlings. This research was a Completely Randomized Design (CRD) with 5 treatments and 4 replications to obtained 20 experiment units, and each of it consisted of 3 plants, so there were total 60 plants. The research was carried out in the experimental field of the 3rd Campus Andalas University, Dharmasraya. The observation data were analyzed by analysis of variance (F -test) and continued by the Duncan’s New Multiple Range Test (DNMRT) at 5% level significantly. The results showed that the crickets feces manure contained 2.70% N, 0.56% P, 2.24% K, 10.16% C, 3.76% C/N, 1.47% Ca, 0.69% Mg, and 0,28% Na. Application of crickets feces manure influences the growth of cacao seedlings on the variables of plant height, stem diameter, number of leaves, leaf length, and leaf width. Application of crickets feces manure with a dose of 50 g / polybag is the efficient treatment for the growth of cacao seedlings.

Robusta coffee (Coffea canephora) germination takes a long time because robusta coffee beans have a hard seed coat that makes it difficult for water and oxygen to penetrate, causing the germination process to be hampered. The purpose of this study is to determine the gibberellin concentration, and the proper soaking time in the germination of robusta coffee seeds and to obtain the best interaction between gibberellin concentration and soaking time on the viability of coffee seeds that have been peeled. The research was conducted at the Dharmasraya Campus III Seed Technology Laboratory from July to September 2022. This study was a two-factorial experiment in a completely randomized design (CRD). The first factor was the concentration of gibberellins which had four levels: 0, 100, 200, and 300 ppm, the second factor was soaking time which had 3 levels: 8, 16, and 24 hours. The results showed that the treatment with gibberellin of 300 ppm significantly increased seed germination, plumule, radicle elongation, and vigor index on robusta coffee seeds. And, the best soaking time of 24 hours, the long soaking treatment had a significant effect on the germination power of robusta coffee seeds. With the best treatment, a gibberellin concentration of 300 ppm and 24 hours, the interaction between gibberellins concentration and soaking time can increase the germination power of robusta coffee seeds.

Coffee is one of the plantation commodities that has significant economic value. A factor that needs to be considered in coffee plant cultivation is good planting media composition. This study aims to determine the effect of planting media composition on the growth of robusta coffee seedlings. This study used a Completely Randomized Design with treatments M0= Soil: 100%, M1= Soil: 50% + Coffee Husk Compost: 25% + Rice Husk: 25%, M2= Soil: 25% + Coffee Husk Compost: 50% + Rice Husk: 25%, M3= Soil: 25% + Coffee Husk Compost: 25% + Rice Husk: 50%. The analyses conducted were compost analysis and initial and post-incubation soil analysis. Observation data were analyzed using the F test followed by DNMRT at the 5% level. The research results show that the provision of coffee husk compost and rice husks affects the chemical properties of the soil and the growth of coffee seedlings. The planting media composition of Soil: 25% + Coffee Husk Compost: 50% + Rice Husk: 25% proved to increase the pH of the planting media from 5.5 to 6.6, increase in total N-value from 0.2% to 0.5%, available P from 18.6 ppm to 38.5 ppm and the soil CEC from 7.6 me/100g to 36.6 me/100g. This planting media composition also makes it possible to enhance the growth of robusta coffee seedlings in plant height, stem diameter, number of leaves, leaf width, and root volume. Thus, this planting media composition is a suitable medium for the growth of robusta coffee seedlings.
