Abstract

Cocoa (Theobroma cacao L.) is a plantation commodity with high economic value. The need for cacao is increasing but the production yields are decreasing every year, so it is necessary to increase cocoa production. The purpose of this study was to find out how the application of liquid organic fertilizer can increase the growth of cocoa plants and how to apply liquid organic fertilizer to cocoa plants. The research was carried out in several stages, namely making liquid organic fertilizer and planting cocoa plants. This study used a randomized block design with the Least Significant Difference (LSD) test. The results showed that the application of liquid organic fertilizer to cocoa seedling plants had an effect on growth and gave better results than without the application of liquid organic fertilizer. The highest yield was found in the 500 mL/L treatment with an average plant height of 20.67 cm, leaf area of 28.49 cm and an average number of leaves of 5.67.

Abstract

Corn (Zea mays L.) is one of the important food crops in Indonesia and has a strategic role in the Indonesian national economy as the main food crop which not only provides food, but is also a source of animal feed and industrial raw materials. This research aims to determine the effect of applying liquid organic fertilizer from goat manure to increase the growth of corn plants (Zea mays L.). This study used a randomized block design consisting of four treatments and three replications, namely control treatment (J0), 50 mL/L (J1), 100 mL/L (J2) and 150 mL/L (J3). The research stages are preparation of materials, making liquid organic fertilizer from goat manure, planting corn, applying liquid organic fertilizer and maintenance. The results of research on plant height parameters showed that the highest plant height was in treatment J3 (150 mL/L) at 110.67 cm. The highest number of leaves was found in treatments J3 (150 mL/L) and J2 (100 mL/L), amounting to 10.00 and 10.67. The highest leaf area was in treatment J3 (150 mL/L) at 820.25 cm. Goat manure liquid fertilizer contains the nutrients N, P and K that plants need for plant height, number of leaves and leaf area. Key words: corn seeds, goat manure, fertilizer

Abstract

High seed vigor is one of the determining factors for the successful early growth of rice (Oryza sativa L.). However, drought stress often becomes a constraint in rice cultivation because it can inhibit water imbibition, reduce germination, growth synchrony and decrease the vigor index. Therefore, efforts are needed to maintain seed vigor in water limited conditions, one of which is through the application of liquid organic fertilizer (LOF) from goat manure. This study aims to examine the effect of the application of liquid organic fertilizer from goat manure on rice seed vigor under drought conditions. The parameters observed were germination power, growth synchrony and vigor index. The results showed that the application of 50 mL and 100 mL of goat manure LOF had a significant effect on germination power, growth synchrony and vigor index. This is because the organic acid content from the fermentation of LOF is able to dissolve and wash out some of the dissolved salts. Goat manure organic fertilizer (LOF) contains macronutrients (N, P, K), micronutrients and fermented organic compounds that support seed metabolism, stimulate root growth and improve plant adaptation to drought conditions.

Abstract

Tanaman padi wakawondu merupakan tanaman pangan lokal unggulan masyarakat Buton khususnya Desa Lawele, Kecamatan Lasalimu. Budidaya padi lokal wakawondu sudah jarang dilakukan di lahan kering karena rendahnya hasil produksi sebagai akibat menurunnya kesuburan tanah. Penyebab menurunnya kesuburan tanah adalah adanya aktivitas pertambangan aspal yang terjadi daerah tersebut. Degradasi lahan tidak dapat dihindari sehingga ketersediaan hara tanah pada daearah tambang aspal menjadi rendah. Pemupukan menggunakan bahan organik sangat perlu dilakukan guna memperbaiki kondisi hara pada lahan tambang aspal untuk budidaya padi wakawondu. Tujuan penelitian ini adalah untuk mengetahui peran pupuk hilado (hijau lamtoro dan dolomit) dalam merevitalisasi lahan tambang aspal untuk pertumbuhan padi wakawondu. Penelitian ini dilaksanakan di Desa Lawele Kecamatan Lasalimu Kabupaten Buton. Waktu penelitian pada bulan Juni-September 2025. Penelitian ini menggunakan metode Rancangan Acak Kelompok (RAK) yang dilakukan dengan 4 perlakuan dengan 3 kali ulangan sehingga terdapat 12 unit percobaan. Taraf dosis yang digunakan yaitu P0 = tanpa perlakuan (kontrol), P1 (Dosis 25% pupuk hilado), P2 (Dosis 50% pupuk hilado), dan P3 (Dosis 75% pupuk hilado). Hasil penelitian menunjukkan bahwa aplikasi dosis pupuk hilado tidak memberikan pengaruh nyata terhadap pH tanah (7) namun memberikan pengaruh nyata terhadap tinggi tanaman 79.73, jumlah anakan 41.44, dan indeks kehijauan daun 3.83. Perlakuan terbaik terdapat pada perlakuan P2 (dosis 50% pupuk hilado) untuk semua variabel pengamatan. Hal ini diduga dosis 50% mampu mensuplai ketersedian hara bagi tanaman. Wakawondu rice is one of the best food crops of the Buton community, particularly in Lawele Village, Lasalimu District. Its cultivation is rarely carried out on dry land due to low production yields as a result of declining soil fertility. The cause of this decline is the asphalt mining activities that occur in this area. Land degradation cannot be avoided, so the availability of soil nutrients in asphalt mining is low. Organic fertilization is therefore critical to restore soil productivity in this wakawondu cultivation area. This study aims to determine the role of Hilado fertilizer in revitalizing the asphalt mining land for wakawondu rice growth. This study was conducted in Lawele Village, Lasalimu District, Buton Regency. The research period was June to September 2025. This study used a Randomized Block Design (RBD) method, which was carried out with 4 treatments with 3 replications, so that there were 12 experimental units. The dosage levels used were P0 = no treatment (control), P1 (25% dose of Hilado fertilizer), P2 (50% dose of Hilado fertilizer), and P3 (75% dose of Hilado fertilizer). The result of the study showed that the application of Hilado fertilizer doses did not have a significant effect on soil pH (7) but had a significant effect on plant height 79.73, number of tillers 41.44, and leaf greenness index 3.83. The best treatment was in the P2 (50% dose of Hilado fertilizer) for all observation variables. It is hypothesized that the 50% application rate provides sufficient availability to support plant growth.
