Abstract

Appropriate weeds control is needed against weeds constraints in field, especially the organic field. With the appropriate management, weeding would benefit the organic field not only in reducing weeds but also in increasing nitrogen (N) availability in organic rice fields. This research aims to observe soil available N changes affected by weeding frequencies in organic paddy fields. Treatments applied were five weeding frequencies (WF) such as 0 WF, 2 WF, 4 WF, 6 WF, and 8 WF, to study the effect of various weeding frequencies on soil total N and available N ( NH4+ and NO3–) in the organic rice field. The soil in the conventional field was analyzed as a comparison to organic field soil. The results showed that soil C and N contents are similar in all treatments. Meanwhile, 6 WF performed the highest soil  NH4+ among organic plots (10.36 mg N kg–1) and 8 WF enhanced soil NO3– to the highest average among all plots (10.12 mg N kg–1). The treatment of 6 WF and 8 WF also maintain the increase of soil  NH4+ to 51 days after transplanting (DAT), meanwhile 0 WF, 2 WF, and 4 WF decreased after 40 DAT. Water samples from fields inlet-outlet and river showed that  NH4+ content found in water sample was higher than NO3–. We concluded that the more frequencies of weeding applied to organic fields potentially preserved soil inorganic N longer, which is very important in supporting rice growth.

Abstract

The utilization of wetlands as agricultural land requires specific processing techniques, which are relatively expensive and unaffordable for local farmers. The optimization of wetlands as agricultural land by local farmers is usually made by elevating a certain part using the adjacent soil material known as Surjan system. The land management using Surjan system increases the diversity of agricultural products and deals with inundation problems. However, its environmental impact has not been widely studied. The research was conducted by observing the land with Surjan system in Kulonprogo area to determine its characteristics. Interviews with farmers were conducted to determine land management techniques. Soil and gas emissions samples were taken based on the age of the crop. The characteristics of land with Surjan system and conventional rice field were then compared to determine the difference, and the implications of the two agricultural lands on the environment are discussed. Surjan system can increase land productivity, and it can be adopted easily by farmers in other areas with inundation problems. This system is a planting system consisting of mound (the raised beds) and tabukan (the sunken beds that remain inundated). The mound part can be planted with secondary crops, horticulture, and other dryland crops, while the tabukan part can be planted with rice and used for mina padi (rice-fish) farming system. Surjan system provides benefits for environmental management through the prevention of floods and eutrophication, as well as reduction of greenhouse gas emissions in the atmosphere. Land management through Surjan system affects soil pH, redox potential, and organic matter. Land with Surjan system produces lower methane gas emissions than conventional rice fields. It produces methane gas of 4.06 - 45.73 µg / m2 / minute, with soil pH, redox potential, and organic matter of 6.65 - 7.69, (-) 49 - 10 mV, and 1.28 - 3.59%, respectively

Abstract

Nature on Soil Phisical, Chemical and Ftir Spectrophotometry of Hydrophobic Peat From Central Kalimantan (S.N.H. Utami, A. Maas, B. Radjagukguk, and B.H. Purwanto): Peat soils naturally have hydrophilic or water-loving character with highly capable of exchanging the cations and cycling the nutrients from the vegetations. This water-loving character is altered to water-repellent character in hydrophobic peat soils. This research was aimed to observe deeply the functional bunch carrier of hydrophobic and hydrophilic peat soils as shown by FTIR spectra in relation with inherent chemical and physical properties of the soils. Five peat soils consisted of two native and artificial hydrophobic peat soils and one sample of hydrophilic peat soils were studied. Artificial hydrophobic peat soils were yielded by oven-drying the native hydrophobic peat soils at 50 oC for 10 hours. FTIR spectra can distinguish the functional bunch carrier of hydrophobic and hydrophilic peat soils. FTIR spectra of hydrophobic peat soils showed degradation of hydrophilic bunch carrier (¾OH and ¾COOH) and increase of the hydrophobic bunch carrier (tying aromatic from esther and ether). Chemical analysis  of the hydrophobic peat soils also indicated the decrease of ¾OH and ¾COOH content, decrease of CEC , soil total acidity and soil moisture content.

Abstract

ABSTRACT. Catharanthus roseus, formerly known as ornamental plant, has now been explored for its potentials as medicinal herb. One of the secondary metabolites produced, namely vinblastine, has been widely used to treat some human cancers. In addition, as the relatively high tolerance to drought, the plant species could produce proline, which plays important role in maintaining cellular osmotic pressure in an adverse condition. This study aims to assess the profiles of vinblastine and proline in C. roseus cultivated on inceptisol under water stress in combination with the applications of Zwavelzure Ammonium (ZA) fertilizer and rice husk biochar (RHB). A Split Plot Design was employed involving three treatments, namely water stress as the main plot and the combination of ZA fertilizer and RHB as the subplot. Three levels of the respective treatment were applied, namely 0, 2 and 4 days without watering; 0; 1.19 and 2.38 g/polybag of ZA fertilizer; and 0, 100 and 200 g/polybag of RHB. The results showed that the highest vinblastine content of 2,516.46 µg/g was obtained in the combination of 4 days without watering, 1.19 g/polybag ZA fertilizer and 200 g/polybag RHB. Meanwhile, the highest proline content of 31.62 µmol/g was found in the applications of 4 days without watering, 2.38 g/polybag ZA fertilizer and 0 g/polybag RHB. The supporting agronomic parameters revealed the best responses in the applications of daily watering, 2.38 g/polybag ZA fertilizer and 200 g/polybag RHB. It can be concluded that the production of vinblastine increases with the higher levels of water stress, ZA fertilizer and RHB, while that of proline increases with only the higher water stress and RHB. ZA fertilizer and RHB applications are shown to increase soil fertility, while daily watering optimizes the growth of C. roseus. Key words: Catharanthus roseus, inceptisol, proline, vinblastine, water stress

Abstract

The Wanagama 1 Forest, owned by Universitas Gadjah Mada  in Playen, is an educational and research forest that is home to different species of trees that are managed and treated differently. Finding the quality index values for different cropping strategies in plot 17 of Wanagama Educational Forest 1 was the aim of this study. The soil quality index was determined using three methods: simple addition, scoring and weighting, and summation. The results show that in plot 17 of the Wanagama forest, the highest soil quality index values were found for ebony species and the lowest soil quality index values were found for mahogany and Eucalyptus species. The results showed that all land uses with different types of forest plants had lower soil quality indices. The stepwise analysis results showed that porosity, organic C, cation exchange capacity (CEC), P availability, K availability, and C biomass influenced the soil quality index. Measuring soil quality can help you learn more about soil properties and how to improve it through effective management.

Abstract

The type of vegetation and soil organic matter affect the carbon fraction, nitrogen fraction and soil carbon stocks that contribute to the global carbon cycle. Therefore, the calculation of the composition of the fractions in different land covers is very important as a potential indicator of the effect of land management practices on soil organic carbon dynamics and supports the reduction of carbon dioxide (CO2) and soil carbon storage. This research aimed to determine the composition of the carbon fraction, nitrogen fraction and soil carbon stock in different land cover. There were six types of land cover with vegetations of 10-year-old bamboo, 30-year-old bamboo, 50-year-old bamboo, bulrush, a mixture of brushwood and bulrush, and a mixture of Albizia falcataria and brushwood, each of which was sampled three times. Soil samples were used to determine microbial biomass, particulate organic, humic acid, fulvic acid and soil carbon stock. The six land cover types showed significant differences in all fractions and soil carbon stocks. Fifty-year-old bamboo vegetation has the highest carbon storage of 0.029 g g-1 soil. The stable carbon fraction, in the form of humic acid and fulvic acid, in 50-year-old bamboo vegetation is more excellent than that in other vegetation. This study shows that 50-year-old bamboo vegetation has the potential to sequester carbon and store carbon in forms that decompose slowly, namely humic acid and fulvic acid, in the soil for a longer period.

Abstract

This community service program aims to address low productivity and improve the implementation of Standard Operating Procedures (SOPs) for seedless watermelon cultivation in Sleman Regency, Special Region of Yogyakarta, from November 2023 to January 2025. Farmers face obstacles in land management, fertilization, and pest control, and are influenced by limited capital, fertilizer availability, and traditional farming mindsets. This activity aims to improve farmers' ability to partner with the private sector to achieve the target of supplying five tons of watermelon per week. The implementation method uses a participatory empowerment model that actively involves farmers in the processes of problem identification, training, application of cultivation technology, and evaluation of activities. The implementation of activities includes problem identification, technical cultivation training according to SOPs, direct field assistance, and evaluation of results using the before-and-after method to compare changes in SOP implementation and productivity achievements before and after mentoring. Evaluation indicators include the level of SOP implementation, harvest productivity (tons/ha), and yield quality based on watermelon grading. The results of the activity showed an increase in SOP implementation, especially in bed preparation, balanced fertilization, and integrated pest control. Farmer productivity in several planting cycles reached more than 10 tons/ha, with the highest achievement of 18.78 tons/ha, while the average productivity was close to the target range of 5–10 tons/ha. In terms of yield quality, the percentage of Grade A fruit among some farmers reached 31.64–36.08%, close to the quality target of 30–50%, while Grade B fruit still dominated the yield, ranging from 44.87–63.92%. From a socio-economic perspective, this activity also strengthened farmers' ability to manage their businesses and expand market access through the integration of sustainable partnerships.Program pengabdian kepada masyarakat ini dilakukan untuk mengatasi rendahnya produktivitas dan belum optimalnya penerapan Standar Operasional Prosedur (SOP) budidaya semangka tanpa biji di Kabupaten Sleman, Daerah Istimewa Yogyakarta selama November 2023 hingga Januari 2025. Petani menghadapi kendala dalam pengelolaan lahan, pemupukan, dan pengendalian hama, serta dipengaruhi oleh keterbatasan modal, ketersediaan pupuk, dan pola pikir tradisional dalam bertani. Kegiatan ini bertujuan untuk meningkatkan kemampuan petani untuk bermitra dengan sektor swasta agar mampu mencapai target pasokan lima ton semangka per minggu. Metode pelaksanaan menggunakan pendekatan participatory empowerment model yang melibatkan petani secara aktif dalam proses identifikasi masalah, pelatihan, penerapan teknologi budidaya, dan evaluasi kegiatan. Pelaksanaan kegiatan meliputi identifikasi masalah, pelatihan teknis budidaya sesuai SOP, pendampingan langsung di lapangan, serta evaluasi hasil menggunakan metode before-after untuk membandingkan perubahan penerapan SOP dan capaian produktivitas sebelum dan sesudah pendampingan. Indikator evaluasi meliputi tingkat penerapan SOP, produktivitas panen (ton/ha), dan kualitas hasil berdasarkan grading buah semangka. Hasil kegiatan menunjukkan adanya peningkatan penerapan SOP, terutama dalam pembuatan bedengan, pemupukan berimbang, dan pengendalian hama terpadu. Produktivitas petani pada beberapa siklus tanam mencapai lebih dari 10 ton/ha, dengan capaian tertinggi sebesar 18,78 ton/ha dan rata-rata produktivitas kategori mendekati target berada pada kisaran 5–10 ton/ha. Dari aspek kualitas hasil, persentase buah Grade A pada beberapa petani mencapai 31,64–36,08%, mendekati target mutu 30–50%, sedangkan komposisi Grade B masih mendominasi hasil panen dengan kisaran 44,87–63,92%. Dari sisi sosial-ekonomi, kegiatan ini juga memperkuat kemampuan petani dalam manajemen usaha dan memperluas akses pasar melalui integrasi kemitraan yang berkelanjutan.
