Spent Bleaching Earth (SBE) is a by-product of the refining of Crude Palm Oil (CPO) into cooking oil which is classified as hazardous and toxic materials waste. SBE has the potential to be used as a filler in the production of NPK fertilizer. This study aims to compare the effect of SBE and Deoiled Bleaching Earth (DBE) as the replacement of clay mineral, which is expected to have the same effect as the control treatment in terms of the leaf area, total dry weight, plant height and yield of plant. This experiment used a one-factor Randomized Complete Block Design (RCBD) with three replicates. The treatments of filler in NPK fertilizer were 10% clay minerals, NPK with 5% clay mineral + 5% SBE filler and NPK with 5% clay mineral + 5% DBE filler. Fertilizer was given twice, ie when the plant was 14 days after planting (DAP) as much as 2 g polybag-1 and age 35 DAP as much as 3 g polybag-1 at each treatment. The results showed that the application of NPK fertilization with 5% clay mineral + 5% SBE filler and NPK fertilization with 5% clay mineral + 5% DBE filler had the same effect as NPK fertilization with 10% clay mineral filler on leaf area, total dry weight, plant height and yield of plant. SBE and DBE can be used as substituties for clay mineral in NPK fertilizer production.

Cocoa plant (Theobroma cacao L.) is one of good annual crops grown in Indonesia. The disadvantages and advantages of Ca in plants can affect morphology and anatomy in plants. This research aimed to identify the effect of Ca on the anatomical performance of the roots of cocoa plants and determine the optimal dose of Ca for the anatomical characteristics of the roots of cocoa plant. The research was conducted at the cocoa plantation owned by PT. Pagilaran at North Segayung Production Unit, Tulis Subdistrict, Batang Regency, Central Java, in October 2019 – February 2021. The observation of root anatomy was carried out by making preparations, and the plant roots were taken destructively and sliced transversely. The field experiment was arranged using a single factor randomized complete block design. The treatments consisted of without fertilizer application and calcium fertilization at a dose of 100 g/tree/year, 200 g/tree/year, 300 g/tree/year, and 400 g/tree/year. The cocoa clone used was clone RCC 71. The results showed that an increase in the dose of CaCl2 fertilizer up to 400 g/tree/year was generally followed by an increase in the size of the xylem and phloem diameters, the thickness of the cork layer, the thickness of secondary cortex, and the diameter of the stele. The quadratic effect of the dose of CaCl2 fertilizer was observed only on the thickness of the root cambium tissues. Thus, it is necessary to conduct further research to determine the optimal dose of Ca fertilizer for the anatomical characteristics of cocoa roots.

Background: The development of tabulampot cultivation for residents of Sendowo Hamlet Yogyakarta has been carried out since 2020 with the aim of improving the function of narrow spaces and improving various nutrients in the family. Continuing the tabulampot cultivation assistance activities, the Department of Agricultural Cultivation, Faculty of Agriculture UGM in 2021, carried out a community service program in the form of propagation, maintenance, and processing of tabulampot cultivation products in Sendowo Hamlet. The processing of tabulampot cultivation results aims to provide art/skills in processing various tabulampot cultivation products. Method: With low production price, easy manufacturing method, and long-lasting results, then making mango jam is the right choice of training ideas for the people of Sendowo Hamlet. The number of trainees consists of 10 people. This activity is carried out by community education methods in the form of training and counseling. Result: The Service activity received a positive response from the people of Sendowo Hamlet. Conclusion: This activity has educated and increased the interest of the people of Sendowo Hamlet in producing mangoes harvested from tabulampot into processed products in the form of mango jam.

The objective of the study was to study the effects of spent bleaching earth (SBE) and deoiled bleaching earth (DBE) filler-based NPK fertilizers on the agronomical characteristics of soybean as a model crop. A field experiment was arranged in a single factor of randomized complete block design (RCBD) with four blocks as replications. The treatments were 1) NPK fertilizer with 10% of BC (control), 2) NPK fertilizer with 5% of BC + 5% of SBE, and 3) NPK fertilizer with 5% BC + 5% DBE. The variables observed were the levels of heavy metals in leaf tissue and the agronomic characteristics of soybean plants. The observations were made on several variables of agronomical crop characters. The data were then analyzed with analysis of variance (ANOVA) at 5% levels and continued with the Least Significant Difference (LSD) test if there were differences among treatments. The results confirmed that the SBE and DBE materials could partly replace the filler components in NPK fertilizers, which has been proven to have the same impact on the agronomical characteristics of soybean in the form of leaf area, root volume, number of pods per plant, number of seeds per plant, and seed yield per hectar.

Indonesia population predicted to reach 304.9 million in 2035 and requires 70% more rice as food supply than today. The fulfillment of food supply experienced constraints such as submergence and salinity caused by climate change. Salinity and submergence stresses may occur in the same time, and the crop response to them has not been widely known. Research has been done to find out the responses of rice to salinity and submergence. The submergence level as the first factor consists of three levels (without submergence (R0); one-week submergence (R1); And two-week submergence (R2)}, salinity level as a second factor consists of two levels {non saline (S1); And saline (S2) to obtain six combinations and each combination is repeated three times. Observations were made on the ratio of the leaf area ratio, the typical leaf area, the canopy -root ratio, the typical leaf weight and the canopy growth rate of the canopy. The weight of grain per clump becomes the observed production parameter at the end of the generative phase. The results showed that there was interaction between submergence duration and salinity level on leaf area ratio, typical leaf area, and canopy-root ratio. Observation of typical leaf weight and relative growth rate showed the treatment of submergence and salinity gave an individual effect. Two weeks of submergence cause plant to death. The saline treatment in all submergence levels resulted in a decrease in the weight of grain per hill. Plants survived one-week non-saline submergence, but two weeks non-saline submergence caused the plant to di
