Abstract

The use of organic materials as fertilizers is an important effort to improve soil fertility and crop productivity sustainably. Gliricidia sepium (gamal leaves) is a leguminous plant rich in nutrients such as nitrogen, phosphorus, and potassium, and contains bioactive compounds and microbes that support plant growth. Liquid organic fertilizer (LOF) made from fermented gamal leaves offers advantages including ease of application, high nutrient absorption by plants, and environmental friendliness compared to synthetic chemical fertilizers that may cause pollution and other negative impacts. This study aimed to evaluate the effect of LOF from gamal leaves on the growth and yield of Japanese cucumber (Cucumis sativus L.). The research was conducted at the Experimental Garden of the Faculty of Agriculture, UKI Toraja, South Sulawesi, from April to July 2025. The LOF was produced by fermenting gamal leaves for 15 days using EM-4 solution and palm sugar as activators. The LOF was applied three times at two-week intervals, starting at 7 days after planting (DAP), by soil drenching around the base of the plants. Observed variables included plant height, number of leaves, leaf area, stem diameter, number of fruits per plant and per plot, average fruit diameter and length, and fruit weight per plant and per plot. Data were analyzed using analysis of variance (ANOVA) and the Honestly Significant Difference (HSD) test at a 0.05 significance level. The results showed that application of LOF from gamal leaves at a dose of 300 ml per plant produced the best results across all observed parameters, including plant height, leaf number and area, stem diameter, fruit number, fruit size, and fruit weight per plant and per plot.

Abstract

Strengthening the local economy through better access to agricultural facilities and local marketing strategies is key to empowering rural communities. Lembang Tondon, with its significant agricultural potential, faces challenges such as limited production facilities, fluctuating commodity prices, and reliance on middlemen. This community service program aims to enhance farmers’ capacity by improving access to agricultural inputs and developing marketing strategies. Methods such as surveys, interviews, focus group discussions, and participatory rural appraisal were used to assess the situation and identify opportunities for improvement. Results show that strengthening local institutions, optimizing farmer groups, and implementing direct marketing strategies can boost farmers' income and bargaining power. Collaboration between farmers and stakeholders reduces reliance on intermediaries, creating a more sustainable supply chain. Additionally, training in financial literacy, market analysis, and negotiation skills ensures long-term success. This program supports sustainable rural economic development, food security, poverty reduction, and local resilience, emphasizing the integration of agricultural development with community-driven marketing solutions.

Abstract

The Thematic Community Service Program (KKN-T) by students of the Indonesian Christian University of Toraja in Tondon Langi Village, Tondon District, focuses on reforestation as an effort to preserve the environment while strengthening the community's economy. This initiative is driven by the presence of unused land and the community's road access, which is often blocked due to landslides, hindering their access to livelihood locations like gardens and rice fields. Additionally, there is a lack of awareness about the economic value of trees. The activities carried out include observation, socialization, and the planting of teak and mahogany trees, in collaboration with the local community, police, and TNI officers. These efforts aim to foster environmental awareness and highlight the long-term economic benefits of trees. The program not only promotes environmental conservation but also strengthens social bonds through collaboration and cooperation. By involving all stakeholders, this activity seeks to build a greener, more sustainable village, encouraging the community to see trees as a valuable investment for the future.

Abstract

This study aims to determine the effect of buffalo waste bokashi on the growth of agarwood seedlings and the economic value of buffalo waste bokashi business. This study was conducted at the Malimbong Balepe agricultural extension center, Tana Toraja Regency, South Sulawesi, from August to December 2025. The study was conducted using a randomized block design (RAK) with 4 treatment levels, namely; B0 (without bokashi), B1 (200 grams/plant), B2 (400 grams/plant), and B3 (600 grams/plant). The parameters observed were plant height, number of leaves, stem diameter, and root volume. Data were analyzed using a combined analysis of variance (ANOVA), while for farming business analysis using the R/C ratio, Break Event Point (BEP) and Return On Investment (ROI). The results showed that the B3 treatment (600 grams/plant) was the best treatment for plant height, leaf number, stem diameter, and root volume. The buffalo waste bokashi business had an R/C ratio of 2,80, ROI 180% indicating that this business is feasible.

Abstract

Penelitian dengan judul Pemanfaatan bokashi dari limbah ternak kerbau sebagai sumber pupuk organik untuk menigkatakan produkasi tanaman Mentiumun(Cucumis sativus)di lakasanakan di Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk bokashi yang berasal dari limbah ternak kerbau terhadap pertumbuhan dan produksi tanaman mentimun (Cucumis sativus), serta menganalisis kelayakan usaha tani dari penggunaannya. Penelitian dilaksanakan di Kecamatan Sa’dan, Toraja Utara pada februari-juni 2025 dengan rancangan acak kelompok (RAK) satu faktor Ilmia taraf yaitu; P0 (kontrol),P1 (300g/polybag), P2 (400g/polybalybag) P3 (500g/polybag) dan P4 (600g/polybag), masing-masing di ulang tiga kali. Parameter yang diamati pada tanaman Mentimun dengan Komoditi. Mentimun ini dikenal dengan warna buah hijau gelap, ukuran sekitar 24 x 6 cm, dan dapat dipanen pada umur sekitar 34 hari setelah tanam (hst ditanam di dataran rendah hingga menengah. meliputi tinggi tanaman, panjang batang utama, jumlah daun, diameter batang, jumlah bunga, jumlah buah, berat buah, serta ukuran buah. Hasil penelitian menunjukkan bahwa pemberian pupuk bokashi limbah ternak kerbau berpengaruh nyata terhadap sebagian besar parameter pertumbuhan dan hasil tanaman mentimun. Perlakuan P2(400/g polybag) memberikan hasil terbaik pada tinggi tanaman mentimun, jumlah per petak. Analisis usaha tani menunjukkan nilai R/C ratio sebesar 1,04, yang berarti usaha layak dijalankan karena setiap biaya Rp1,00 menghasilkan penerimaan Rp1,04. Nilai BEP produksi tercapai pada 1,139 kg dengan BEP harga jual sebesar 3.861,00/kg. Dengan demikian , Pepupuk bokashi dari limbah ternak kerbau berpotensi menjadi alternatif pupuk organik yang efektif meningkatkan hasil tanaman mentimun sekaligus mendukung praktik pertanian berkelanjutan yang ramah lingkungan
