The use of synthetic dyes in the textile industry has caused various environmental problems due to waste that is difficult to degrade and has the potential to contaminate water and soil. Therefore, the development of environmentally friendly natural dyes is an important alternative to be explored. One potential but underutilized source of natural dye is kirinyuh weed (Chromolaena odorata L.), which is known to contain natural pigment compounds such as tannins and flavonoids. This study aims to analyze the dyeing quality of primissima cotton fabric using kirinyuh leaf extract with variations of alum and ferrous mordants through a mordanting process. The research employed an experimental method, including hot extraction of kirinyuh leaves, dyeing of primissima cotton fabric, and mordanting using alum and ferrous salts. The evaluation of dyeing quality focused on washing color fastness and light color fastness tests based on standard textile testing methods. The results indicate that the type of mordant significantly affects the resulting color quality. Alum mordant produced relatively lighter colors with good washing fastness, while ferrous mordant resulted in darker shades with similarly good washing fastness. However, color fastness to light showed relatively lower values, particularly in fabrics treated with alum mordant. Based on these findings, it can be concluded that kirinyuh leaf extract has the potential to be used as a natural dye for primissima cotton fabric, although further optimization is required to improve color resistance to light exposure.

This study aimed to evaluate the effectiveness of liquid organic fertilizer (POC) derived from kirinyuh (Chromolaena odorata) leaves on the growth and yield of potted corn plants. The research was carried out at the Agricultural Development Center (BPP) of Malimbong Balepe’, Tana Toraja District, South Sulawesi Province, located at an altitude of 815 meters above sea level. The experiment was designed using a simple randomized block design (RBD) consisting of four treatments: K0 = control (without treatment), K1 = 20% concentration of kirinyuh leaf POC (200 ml POC + 800 ml water), K2 = 40% concentration of kirinyuh leaf POC (400 ml POC + 600 ml water), and K3 = 60% concentration of kirinyuh leaf POC (600 ml POC + 400 ml water). Parameters observed included plant height at 5 and 7 weeks after planting (WAP), number of leaves at 7 WAP, ear length, ear diameter, and ear weight per plant. The results showed that kirinyuh leaf POC significantly affected the growth and productivity of potted corn plants. Application of POC at 60% concentration (K3) produced the best results, indicated by increased plant height, greater number of leaves, longer ear length, larger ear diameter, and higher ear weight compared to other treatments and control. This finding suggests that kirinyuh leaves, which are often considered as agricultural weeds, have potential as an alternative source of organic fertilizer that is environmentally friendly, low-cost, and effective in improving crop growth and yield. In conclusion, kirinyuh leaf-based liquid organic fertilizer, particularly at a concentration of 60%, demonstrated the highest effectiveness in supporting corn growth and productivity. These results provide practical insights for farmers to utilize locally available organic materials as an alternative to chemical fertilizers in sustainable agricultural practices.

The use of liquid organic fertilizer (POC) is an innovative solution to increase crop productivity in drylands that face challenges in soil fertility and water availability. This study aims to evaluate the effect of various types of POC, including moringa, kirinyu, rabbit urine, fermented fruit waste, and local microorganism-based (MOL) POC, on plant growth and yield. The method used was literature review and analysis of literature from various journals, theses, theses, and dissertations, which were analyzed descriptively and quantitatively.  The results showed that all types of POC increased plant productivity with an average increase of 20-40% compared to the control, with rabbit urine recording the highest increase of 40%. The effectiveness of POC comes from the content of nutrients, bioactive compounds, and microorganisms that improve soil structure, increase water retention, and spur nutrient absorption. The discussion underscored the importance of utilizing local resources to reduce environmental pollution and improve agricultural sustainability.  In conclusion, POC proved to be an effective alternative to increase crop yields in drylands while supporting sustainable agriculture. Recommendations for further research include further exploration of local organic materials and application of POC on a field scale.

Kegiatan pengabdian kepada masyarakat di Desa Masebewa Kecamatan Paga Kabupaten Sikka ini bertujuan untuk mendorong masyarakat dalam memanfaatkan hijauan kirinyu (Chromolaena Odorata) yang berpotensi untuk meningkatkan kesuburan tanah. Selama ini kirinyu hanya dianggap sebagai tumbuhan pengganggu tanaman budidaya, yang dapat merugikan kegiatan usahatani. Sebaliknya kirinyu mengandungan unsur hara makro dan mikro yang dibutuhkan oleh tanaman untuk dapat bertumbuh dan berproduksi. Pemanfaatan kirinyu sebagai pupuk organic dapat mengurangi penggunaan puun anorganik yang dapat mencemari lingkungan. Untuk itu, telah dilakukan penyuluhan dan praktek pembuatan puuk organik. Kegiatan ini dilaksanakan di Desa Masebewa Kecamatan Paga. Kegiatan ini mendapat dukungan penuh dari apparat Desa, masyarakat dan pemerintah Desa.
