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.

Organic hydroponics based on liquid organic fertilizer. Research on the cultivation of Kailan (Brassica oleracea var. achepala) plants using an organic hydroponic system based on organic fertilizers (POC), was conducted at the experimental garden of Pasraman Unud Jimbaran from March to June 2020. The liquid organic fertilizer used consisted of two types of MOL, namely bamboo shoots MOL and banana weevil MOL. The purpose of this research is to find an organic medium (nutrient solution) that is cheap, easy and environmentally friendly as an alternative substitute. AB mix (inorganic nutrients) which has been used in hydroponic systems. The experimental design used in this study was a Randomized Block Design. Using liquid organic fertilizer from MOL Bamboo Shoots (R) and MOL Banana Hump (B). The treatments consisted of: K (without MOL); K+ (without MOL +AB mix) ; R1& B1 ( 50 ml/L ); R2 & B2 (100 ml/L) ; R3 & B3 (150 ml/L); and R4 & B4 (200 ml/L), there were 10 treatments with 3 replications, so there were 30 experimental units. Initial analysis of the media was carried out on the levels of N, P, K, pH and EC. Parameters measured were number of leaves, plant height, wet weight, plant dry weight. The results showed that hydroponics by only relying on liquid organic fertilizer as a source of nutrition, was not able to support normal plant growth. Wet weight, dry weight and plant height of Kailan in the MOL treatment of banana weevil and MOL of bamboo shoots showed much smaller results, namely 1/10 compared to the AB mix (K+) treatment.

Mapping of Schmidt-Ferguson Climate Classification and Agroclimate Suitability of Red Chili Plant (Capsicum annuum) in Bali Province. Climate tends to be dynamic and changes continuously, as well as climate elements that continue to change in an area. Along with climate change and increasing rain gauge posts, the possibility of changes in climate types based on the Schmidt-Ferguson classification is inevitable. Thus, it is necessary to map the Schmidt-Ferguson climate classification in Bali Province based on data from 1991-2020 to provide an overview of the latest Schmidt-Ferguson climate classification in Bali Province. One of its uses is for the suitability criteria for agroclimatic zones for red chili (Capsicum annuum) plants. This study uses rainfall data from 1991-2020 from BMKG. This distribution data will be used to determine the Schmidt-Ferguson climate type. These results are related to the land suitability requirements for red chili (Capsicum annuum) land crops. GIS mapping will assist in zoning the Schmidt-Ferguson climate type classification area in Bali Province. The results of this study provide an overview of the latest Schmidt-Ferguson climate classification and agroclimatic suitability for red chili (Capsicum annuum) in Bali. There are significant changes when compared to the Schmidt-Ferguson climate classification for the previous period (1981-2010) with the same location and amount of data. Moreover, red chili (Capsicum annuum) plants are generally able to grow throughout the province of Bali, where the most suitable areas are in the northern coastal area.
