Abstract

Decline in physiological seed quality during storage can significantly reduce viability and vigor, including in Hiyung cayenne pepper, a superior local variety from South Kalimantan. One potential solution is the invigoration technique, which involves treating seeds with certain solutions to restore their quality. This study aimed to examine the effect of shallot extract as a natural invigoration agent and to determine the best concentration to improve the viability and vigor of Hiyung cayenne pepper seeds that have exceeded their storage period. The research was conducted at Seed Control and Certification Center for Food Crops and Horticulture (BPSBTPH) Banjarbaru from July to August 2024 using a completely randomized design with one factor: four solution concentrations (0%, 10%, 15%, 20%) and five replications. Observed parameters included maximum growth potential, germination rate, vigor index, uniformity, and growth rate. The results showed that shallot extract had a significant effect on germination rate and growth rate, but no significant effect on maximum growth potential, vigor index, and uniformity. Application of 10% shallot extract improved seed viability, while 20% concentration enhanced the vigor of Hiyung cayenne pepper seeds that had exceeded their storage period.

Abstract

Plants, water, and peat soil interact to form peatland ecosystems, which are composed of these three interrelated elements. The water balance of peatlands is significantly influenced by the capillarity of the peat soil. This study attempts to ascertain the impact of depth on applying subsurface water retention technology (SWRT) membrane on capillary action based on moisture of peat soil in different    land uses. A completely nested randomized design was utilized in this investigation to avoid bias of the different degree of decomposition between land uses. The type of land use—namely, shrubs (PL1) and agricultural land (PL2) was the first account. The position of the membrane (its depth), which was set at -20 cm (D1), -30 cm (D2), and -50 cm (D3) and in addition to a control treatment without membrane installation (D0), was the second account. Three times each experimental unit was repeated. The YL-100 soil moisture content sensor, which is powered by Arduino, presented the research results. Arduino can produce digital values with a range of 0 to 1023 by converting moisture values that were  output as analog signals into digital values using an analog to digital converter (ADC) with a resolution of 10 bits. The outcome revealed that soil moisture content increasing up to the peat soil layer of 5 to 10 cm until the fifth day of observation due to rainfall along our study that increased the flux of water flow into the peat soil.

Abstract

The purpose of this study was to determine the effect of water lily activated charcoal as a biofilter in tofu wastewater treatment and to determine the effective dose of water lily activated charcoal as a biofilter in tofu wastewater treatment. The results showed that water lily activated charcoal can be used to improve the quality of tofu liquid waste; thus, it can improve the quality of tofu liquid waste which can be seen from the parameters of TSS (Total Suspended Solid). The treatment dose of 2 g of activated charcoal (A3) is the best dose to improve the quality of tofu liquid waste and has complied with the 2014 LH regulation concerning the quality standards of wastewater for the tofu industry, namely the parameters of TSS. The existence of this research can be a reference for further similar research by utilizing organic matter as an alternative in tofu wastewater treatment.
