Abstract

ABSTRAK Development of black rice is quite rapid in Indonesia. The objective of this study was to obtain doubled haploid black rice lines with good agronomic characters through anther culture. Materials used in this experiment were 6 F1 derived from black rice landrace (Melik) and two cultivated varieties (Inpari 13 and Fatmawati): Melik/Inpari13//Inpari13, Melik / Inpari13// Melik, Melik/Fatmawati //Fatmawati///Fatmawati, Melik/ Fatmawati//Fatmawati// /Fatmawati, Melik/Fatmawati, and Melik/Fatmawati//Melik. The experiment was performed using a completely randomized design consisting of 12 replications. An experimental unit was a petri dish containing ± 150 anthers. Results of the anther culture varied widely between crosses. Crosses Melik/Inpari13//Melik, Melik/Fatmawati//Melik, and Melik/Inpari13 //Inpari13 showed the best response on callus induction and plant regeneration compared to the other crosses. Melik / Inpari13 // Melik produced  the highest number of acclimatized plants, the highest number and percentage of doubled haploid: 63 plants, 42 plants and 91.3% respectively. The highest number of doubled haploid having black aleuron layer were obtained by Melik/Inpari13//Melik and Melik/Fatmawati//Melik.Keywords: anther culture, black rice, doubled haploid, regeneration

Abstract

Banana is a climacteric fruit that continues to ripen after harvesting, and the ripening process plays a crucial role in determining its market value, taste, and consumer safety. In Tawangmangu, a highland region of Central Java, many banana fruit sellers still employ traditional and unsafe methods for ripening, including the use of non-food-grade chemicals. This community service program aimed to enhance the knowledge and practices of 10 local banana sellers by providing participatory training on natural and safe ripening techniques, with a focus on Ambon bananas (Musa paradisiaca var. sapientum). The training combined theoretical education with hands-on practice in using ethylene-based and hygienic ripening methods. Pre- and post-test evaluations revealed a significant increase in participants’ understanding of postharvest physiology and food safety. Furthermore, 80% of the sellers demonstrated the ability to construct and apply low-cost ripening chambers using local materials, and reported reduced fruit spoilage, improved customer satisfaction, and increased marketability. The program successfully bridged the knowledge gap and introduced a practical, low-resource solution aligned with sustainable development goals. This model has the potential to be replicated in other rural agricultural markets to improve food safety and support local economic empowerment.

Abstract

Oil palm frond has potential to be utilized as activated charcoal for plant tissue culture as phenolic compound absorber which causes browning and to promote explant growth. The objectives of this study were to produce activated charcoal from palm oil fronds which has characteristics in accordance with Indonesian National Standards (SNI 06-3730-1995) and commercial activated charcoal for plant tissue culture, to obtain larger activated charcoal pores and clean from the impurities, and to find optimum activated temperature in producing oil palm frond’s activated charcoal using physical-chemical activation method. The research design used was a non actorial - completely randomized design consisted of 4 treatments and 3 replications, namely E0 (control, without physical activation), E1 (physical activation of 450 °C), E2 (physical activation of 600 °C), E3 (physical activation of 750 °C). The parameters observed were the yield of activated charcoal (%), moisture content (%), ash content (%), iodine absorption (mg/g), volatile matter (%) and surface morphology of activated charcoal. The yield of activated charcoal ranged from 0.56 to 1.09%. All treatments significantly affected moisture content, ash content, iodine adsorption, and volatile matter. Overall, the characteristics of the activated charcoal met the SNI standards and commercial tissue-culture charcoal, except for moisture content. The 750 °C activation temperature (E3) was identified as the optimum condition, producing low moisture and ash content, high iodine adsorption, low volatile matter, and larger, cleaner pore morphology
