Abstract

Patchouli (Pogostemon cablin Benth.) is one of the essential oil-producing plants which is Indonesia's leading export commodity so that it can contribute foreign exchange for the country. Patchouli production nationally is still fluctuating and the productivity of patchouli oil is still relatively low. Therefore, proper patchouli cultivation techniques are needed. Plant distance is an important factor in determining the quality and quantity of production. In addition, the use of superior varieties is also a technology that aims to increase the productivity, yield and quality of patchouli oil. This study aims to determine the interaction and analyze the growth and yield of three varieties of patchouli (Pogostemon cablin Benth.) at different plant distance. This research was conducted in October 2021 – March 2022 at the Experimental Garden of Agrotechno Park, Universitas Brawijaya, Jatikerto Village, Kromengan, Malang, East Java. The tools and materials used in this study were tractors, ovens, LAM, scales, hoses, alphaboard, polybags, stationery, cameras, patchouli seeds of Sidikalang variety, Patchoulina 1 variety, Patchoulina 2 variety, planting media, rainfall data, manure, fertilizer. Urea, KCL fertilizer, SP36 fertilizer, raffia rope and water. The design used in this study was the Randomized Block Design which was arranged in a factorial manner consisting of 6 treatment combinations and 4 replications, namely: V1J1: Sidikalang variety + 75 cm x 40 cm plant distance; V1J2: Sidikalang variety + 60 cm x 50 cm plant distance; V2J1: Patchoulina 1 + plant distance 75 cm x 40 cm; V2J2: Patchoulina 1 variety + 60 cm x 50 cm plant distance; V3J1: Patchoulina 2 variety + 75 cm x 40 cm plant distance; V3J2: Patchoulina 2 variety + 60 cm x 50 cm plant distance. The results showed that the treatment of varieties and plant distance had a significant effect on the components of patchouli plant growth. While the yield component of patchouli shows the interaction between varieties and plant distance. The conclusion of this study is that there is an interaction between the treatment of varieties and plant distance on the increase in fresh weight, dry weight and productivity of patchouli. The Sidikalang variety with a plant distance of 60 × 50 cm had the highest yield and oil quality compared to other treatments. The Sidikalang variety also had the highest growth compared to the Patchoulina 1 and Patchoulina 2 varieties. Likewise, the 60 cm x 50 cm plant distance treatment had the highest growth compared to the 75 cm x 40 cm plant distance.

Abstract

Soybean seeds are stored before being planted in the field, during this storage period the seeds can experience deterioration, if not stored in appropriate environmental conditions, seed deterioration will occur more quickly and can reduce the physiological quality of the seeds. The research aims to determine the physiological quality of gamma-ray irradiated black soybean seeds during the storage period. This study used a non-factorial completely randomized design , with control/no irradiation treatment of 0 Gy (R0) and 5 doses of gamma irradiation, including: 50 Gy (R1), 100 Gy (R2), 150 Gy (R3), 200 Gy (R4), 250 Gy (R5), each treatment was repeated four times. The variables observed were electrical conductivity test, seed germination, growing district, germination height, vigor index, and growing simultaneity. The results showed that the higher the dose of irradiation, the lower the percentage of seed germination, and the lower the physiological quality. Key word: Seed storage, Black soybean, Irradiation

Abstract

Rice (Oryza sativa L.) plays a crucial role in Indonesia's food security. The use of high-quality seeds is essential to improve rice productivity. One of the factors affecting seed quality is seed physiology, particularly the physiological processes after harvest, known as after-ripening. After-ripening is a process that enables seeds to germinate after a certain period of dry storage. This study aims to determine the duration of the after-ripening period in several superior rice varieties and identify the variety with the shortest after-ripening period among those tested. The research was conducted at the Seed Analysis Laboratory, Lampung State Polytechnic, from November 2023 to January 2024, using a factorial Completely Randomized Design (CRD). The first factor was the after-ripening period (ranging from 0 to 6 weeks), and the second factor was the rice varieties (Gilirang, Inpari 42, and Inpari 43). Each experimental unit consisted of 100 rice seeds. Data were analyzed using ANOVA and further tested with Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The results showed that the after-ripening period varied among the varieties. The Gilirang variety completed its after-ripening period within 1 week, while Inpari 42 and Inpari 43 required 2 and 3 weeks, respectively. The Gilirang variety demonstrated the shortest after-ripening period, than the Inpari 42 and Inpari 43 varieties.

Abstract

ABSTRACT Climate change is a global challenge that has significant impacts on various sectors of life, particularly agriculture, which relies heavily on climate conditions. The concept of climate-adaptive agriculture, which involves the use of future climate projections, can serve as one solution to address this issue. This Community Service Program was conducted at the Miftahul Jannah Orphanage in Bandar Lampung City, while the farmland managed by the orphanage is located in Natar, South Lampung District, Lampung Province. The program was implemented in the form of agricultural extension activities (lectures, discussions, and demonstrations) in August 2025. Based on the activities, it can be concluded that: (1) through the lectures and discussions, the knowledge of the orphanage members about climate-adaptive farming practices increased by 27%, and (2) through the demonstration activity, the agricultural land of the orphanage was projected to have an Oldeman Climate Type D2 in the next 20 years (2025–2045).
