Abstract

Agarwood (Aquilaria malaccensis Lamk.) is a highly sought-after non-timber forest product due to its valuable resin used in perfumes, medicines, and cosmetics. However, despite its significant commercial potential, agarwood cultivation in Indonesia remains underdeveloped, particularly in Sumatra. Agarwood seedling propagation can be achieved through land extensification, particularly by utilizing marginal lands. In West Sumatra, most marginal lands consist of ultisol soil, which has very low nutrient content. Therefore, the addition of organic matter and microorganisms is necessary to improve soil health and fertility to support plant growth. This study evaluated the effects of Plant Growth-Promoting Rhizobacteria (PGPR) and NASA Liquid Organic Fertilizer (LOF) on the growth of agarwood seedlings in ultisol soil, which is known for its low fertility and high acidity. The experiment employed a Completely Randomized Design (CRD) with two factors: PGPR (0, 10, 20, 30 ml/L) and NASA LOF (0, 20, 30, 40 ml/L). The results showed that the appropriate application of PGPR and NASA LOF significantly enhanced the growth and development of agarwood seedlings, highlighting their potential in improving agarwood cultivation on less productive ultisol soils. The best combination of PGPR and NASA LOF at a dose of 30 ml/L PGPR and 40 ml/L NASA LOF produced the highest average seedling height (82.34 cm) and the greatest number of leaves (38 leaves per seedling), with all seedlings surviving and meeting the quality standards for transplantation.

Abstract

The farmer's interest in garlic planting is low because the yield is unsatisfied. One reason is the use of small cloves. Giving paclobutrazol is expected to increase the size of garlic cloves and bulbs. This research aims to determine the interaction between concentration and time of giving paclobutrazol, which produces the best size for cloves and bulbs. The research is a factorial, Completely Randomized Design. The first factor is the concentration of paclobutrazol:250 mg.L-1 and 500 mg.L-1 of water. The second factor is the time of applying paclobutrazol: 6 and 10, 8 and 12, 10 and 14 weeks after planting (w.a.p). Data were analyzed using variance, which will be continued with DNMRT at the 5% level. The results showed that giving paclobutrazol at 10 and 14 w.a.p resulted in the highest apparent stem diameter and yield, but even so, the weight of the largest and the smallest cloves was the lowest. Meanwhile, giving paclobutrazol at 6 and 10 w.a.p resulted in the highest weight of the largest cloves 1.95 g and the highest of the smallest cloves 0.55 g, even though the apparent stem diameter and yield were the lowest. Treatment of 250 mg.L-1 paclobutrazol resulted in the highest weight of the largest cloves 1.80 g.

Abstract

The government carries out various policies and strategies to support the development of horticulture in Indonesia. One of them is the development of Horticultural Villages such as the Manggis Thematic Village in accordance with the local wisdom of each region which is located in the Limau Manis sub-district, Pauh District, Padang City. Apart from producing mangosteen fruit, this thematic village has also become a tourist icon and can certainly strengthen West Sumatra's position as the largest mangosteen producing area in Indonesia. However, many of the mangosteen plants in this thematic village are old so the quantity and quality do not decline. Apart from that, there is no optimal management from cultivation to harvest. For this reason, it is necessary to socialise the technology to increase mangosteen productivity which aims to increase the knowledge of Tunas Harapan Limau Manis farmer group members in increasing mangosteen production in Kampung Tematik Manggis Limau Manis, Pauh sub-district, Padang city. The activity method used is the socialisation method to members of the Tunas Harapan farmer group. The results of the activity were an increase in the knowledge of farmer group members by 82.8% in applying mangosteen plant management technology to increase mangosteen productivity in the Manggis Limau Manis Thematic village. Apart from that, the activities carried out were also in accordance with community needs and 65% of farmer group members stated that they were very satisfied and that further activities were needed in the future.

Abstract

The Community Partnership Program to Support Business Development is partnering with the Taruko Saiyo Farmers Group in Koto Luar Village, Pauh District, Padang. This farmers' group has approximately 10 hectares of land and has the potential to become a model group in the field of sustainable agriculture. However, several challenges remain, such as limited practices in agricultural waste management, declining soil quality, and farmers' limited literacy and skills in applying appropriate technologies. Based on the identified issues, the solutions offered in this program include: (1) processing agricultural waste into compost, (2) creating biopore infiltration pits, (3) producing biochar from rice husk waste, and (4) implementing agricultural waste mulch made from straw on cultivated crops. This program's primary objective is to enhance partners' capacity in production management and socio-cultural aspects. In addition, this program also aims to improve partners' understanding, skills, and participation in agricultural waste management and the application of appropriate technology to create a more optimal microclimate for plants through the utilization of agricultural waste. Educational and empowerment activities in the Taruko Saiyo Farmer Group have succeeded in increasing the empowerment of farmers, both in terms of production management and socio-cultural aspects. Farmers demonstrated improved understanding and skills in managing agricultural waste by applying appropriate technologies. Additionally, farmer participation in all activities was very high, and some farmers began directly applying the training outcomes on their land. As a sustainability measure, the team also developed technical guidelines and simple documentation that can be used for further learning.

Abstract

This community service activity aimed to enhance the knowledge, skills, and awareness of oil palm farmers regarding the crucial role of the pollinating weevil Elaeidobius kamerunicus in supporting the natural and sustainable increase of oil palm fruit productivity. Currently, the low productivity of smallholder oil palm farms is generally caused by suboptimal pollination processes, a lack of farmer understanding of the biology and life cycle of pollinating insects, and the limited application of environmentally friendly technologies. The implementation methods of this service included counseling, interactive discussions, and field demonstrations on the identification, conservation, and utilization strategies of E. kamerunicus in oil palm plantations. The activity results showed an increase in farmer knowledge by 76.92% (based on pre-test and post-test), improved farmer skills in recognizing and preserving the habitat of the pollinating weevil, and the growth of collective awareness to reduce the use of pesticides that potentially harm pollinator insect populations. The long-term impact of this program is expected to increase oil palm fruit productivity, strengthen the economic resilience of farmers, and support the realization of more environmentally friendly and sustainable oil palm cultivation practices. Thus, this education and empowerment activity makes a real contribution to improving the welfare of oil palm farming communities while preserving the plantation agroecosystem.
