Abstract

In order to fulfill food needs, we need another food resources beside rice. Cassava (Manihot esculenta L.)  is one of the sources food that substitutes the rice. Beside that, utilization of ultisols as cropland can support the efforts to fulfill food needs. This study was conducted to determine the effect of giving Phosphate Solubilizing Fungi (PSF) to one variety (Malang 1) and three accesions of cassava (Sutera, Kuning, and Bayel) on planting in ultisol land. The experiment were conducted with a split plot design, where the main plot consists of PSF and non PSF, while the subplot consists of 1 variety and 3 accessions of cassava. The results showed that addition of Phosphate Solubilizing Fungi (PSF) gives good effects to some characters such as plant height, number of leaves, number of tuber, and tuber weight if compared without PSF. Furthermore, only the Kuning accesion that shows the interaction with PSF for the number of leaves character.

Abstract

Tailings of post-tin mining land have the potential to be cultivation fields for eggplant, but the problem from post-tin-mining land is the low essential nutrient and high metal contents. The quality of land needs to be improved by providing ameliorant such as oil palm empty fruit bunch compost. This research aims to determine the best dosage of oil palm empty fruit bunch compost to production and metal uptake of eggplant in post-tin mining land. This research was conducted from January to May 2019 in post-tin mining land, Dwi Makmur Village, Bangka. This research used a randomized block design with six treatments and four replications. Treatments consisted of organic fertilizer (control) of 15 t/ha(K0), oil palm empty fruit bunch compost 20 t/ha(K1), 30 t/ha(K2), 40 t/ha(K3), 50 t/ha(K4), and 60 t/ha(K5). The results showed that the application of oil palm empty fruit bunch compost of 60 t/ha was the best dose to increase eggplant production in the tailing of post-tin mining land. Application of oil palm empty fruit bunch compost reduced metal absorption of eggplant fruit in tailing of post-tin mining land.

Abstract

A large part of post-tin mining land covered by sand tailing which has low water storage capacity, making it vulnerable to drought stress. The innovation of irrigation technology has been developed to overcome this problem such as capillary irrigation system combined with groasis system using a large reservoir with hydroponic wick system called the growick system. This study aimed to determine the best number and type of wick in growick irrigation system to water consumption and also growth and yield of pakcoy cultivated in sand tailing media. The research was conducted from February to June 2020 at Experimental field of Universitas Bangka Belitung, Indonesia. Treatments consisted of the types of wick (flannel and stove wick) and numbers of wick per polybag (1, 2, 3, and 4 wicks). The study used a completely randomized factorial design with 3 replications. Data obtained were analyzed using Analysis of Variance continued with Duncan's Multiple Range Test (DMRT) at 95% significant level. The result showed that usage of flannel wick gave the highest results of growth and yield of pakcoy but it absorbed more water than stove wick. Flannel wick also had lower water usage efficiency than stove wick. The use of single wick gave the highest result of growth and yield of pakcoy than using more wicks. Results of the study showed that single wick treatment gave the highest growth and yield of pakcoy. Flannel wick gave the highest growth and yield of pakcoy, but it was not significantly different from stove wick. Single flannel wick treatment showed no significant difference with single stove wick treatment in growth and yield of pakcoy except for water usage volume parameter. Flannel wick absorbed more water than stove wick, so it has lower water usage efficiency than stove wick. Application growick system using 1 stove wick was the best treatment for cultivating pakcoy in sand tailing media from post-tin mining land.

Abstract

Waste is a major problem that is often faced by Indonesian people. The existence of waste that has not been handled properly will have a negative impact on the quality of the community's environment. Waste handling with the bioconversion method with the help of Black soldier Fly (BSF) larvae and EM-4 bio-activator can minimize waste capacity and be useful for the community. This study aims to compare the ability between bioconversion agent and quality of various types of organic waste that use for bioconversion. The research was conducted in January – August 2022 at Experimental dan Research Garden (KP2) Universitas Bangka Belitung and Laboratory of Indonesian Center for Biodiversity and Biotechnology. This study used a factorial randomized block design (RAKF) with 2 factors. The first factor were bioconversion agents consist of 3 levels, P0 (control), P1 (EM-4 activator) (15 ml), P2 (Black Soldier Fly) (5 grams/bio-pond). The second factor were different kind of organic waste materials consists of 3 levels, L1 (pineapple peel waste), L2 (orange peel waste), L3 (bagasse). The results showed that BSF larvae had a potential as bioconversion agent and its ability close to EM-4. Generally, application of bioconversion agent increased the quality of compost compare to without application of bioconversion agent.  Application of bioconversion agent combined with pineapple peel waste had quality close to standards from Ministry of Agriculture No. 261, 2019.

Abstract

The Growth of Horticultural Crops on Ex-Tin Mined Soil, Bangka. Growth evaluation of the plant parts consumed from various horticultural species is needed in an effort to determine adaptive economic plant species in ex-tin mined soil. This study aims to determine the growth of crops on ex-tin mined soil and on undisturbed soil in Bangka regency. Three individuals of each species were then measured for their root dry weight, horizontal root length, vertical root length, plant height, stem diameter, canopy width, shoot dry weight, and leaf thickness and leaf area. Plant growth on control land was higher than the growth on ex-tin mined soil for most of the parameters. It is suspected that this is due to the physical, chemical and biotic properties ex-tin mined soil properties which are not yet optimal for growth.
