Potato cultivation in medium-altitude areas offers an opportunity to expand production while reducing environmental pressure in highland areas, but pest management must minimize reliance on synthetic pesticides. This study described environmentally friendly cultivation practices and the use of biopesticides by Granola potato farmers in Bonto Marannu Village, Ulu Ere District, Bantaeng Regency. A descriptive case-study approach was applied to 10 farmers from the Abbulo Sibatang and Samaturu farmer groups. Data were collected through interviews, field observations, and secondary records, then summarized using descriptive statistics and a comparison of reported cultivation indicators. Respondents had an average age of 42.6 years, cultivated 2.50 ha of land, had 10.5 years of farming experience, and produced 14.3 t/ha on average. Reported field indicators showed that biopesticide application reduced pest attack intensity from 40% to 20% and leaf damage from 35% to 15%, while the proportion of grade-A tubers increased from 60% to 75%. However, the comparative production record decreased from 18–19 to 15–16 t/ha. These findings indicate that biopesticides can improve pest suppression and tuber quality, but ecological benefits do not automatically increase yield. Standardization of formulation, dose, application frequency, and economic evaluation is required before the practice can be recommended more broadly. Budidaya kentang di dataran medium berpeluang memperluas wilayah produksi sekaligus mengurangi tekanan lingkungan di dataran tinggi, tetapi pengendalian organisme pengganggu tanaman perlu mengurangi ketergantungan pada pestisida sintetis. Penelitian ini mendeskripsikan teknik budidaya ramah lingkungan dan penggunaan biopestisida oleh petani kentang varietas Granola di Desa Bonto Marannu, Kecamatan Ulu Ere, Kabupaten Bantaeng. Penelitian menggunakan pendekatan studi kasus deskriptif terhadap 10 petani dari kelompok tani Abbulo Sibatang dan Samaturu. Data diperoleh melalui wawancara, observasi lapangan, dan data sekunder, kemudian dianalisis secara deskriptif melalui peringkasan karakteristik responden dan perbandingan indikator budidaya yang dilaporkan. Responden memiliki rata-rata umur 42,6 tahun, luas lahan 2,50 ha, pengalaman bertani 10,5 tahun, dan hasil panen 14,3 ton/ha. Data lapangan menunjukkan bahwa penggunaan biopestisida menurunkan intensitas serangan hama dari 40% menjadi 20% dan kerusakan daun dari 35% menjadi 15%, sedangkan proporsi umbi grade A meningkat dari 60% menjadi 75%. Namun, catatan produksi komparatif menurun dari 18–19 menjadi 15–16 ton/ha. Hasil tersebut menunjukkan bahwa biopestisida berpotensi memperbaiki pengendalian hama dan kualitas umbi, tetapi manfaat ekologis belum otomatis meningkatkan produktivitas. Standardisasi formulasi, dosis, frekuensi aplikasi, dan evaluasi ekonomi diperlukan sebelum praktik ini direkomendasikan secara lebih luas.

Potato productivity in Bonto Marannu Village is constrained by seed quality, crop management, and pest pressure. This study described farmers' cultivation practices and evaluated the production recorded in a demonstration plot that introduced improved land preparation, selected seed, organic fertilization, and plant-based pest management. A descriptive case-study design was conducted from July to September 2024 with 10 potato farmers from the Hortikultura and Gunung Loka farmer groups. Data were collected through field observation, interviews, questionnaires, and documentation, then summarized descriptively. Respondents were 30-52 years old, had 8-20 years of farming experience, and cultivated 0.7-3.0 ha. Farmers commonly prepared raised beds, planted Granola seed at 25 x 30 cm spacing, applied manure and liquid organic fertilizer, controlled pests using gamal-leaf biopesticide, and harvested at 90-100 days after planting. Farmer productivity was reported at approximately 14-15 t/ha, whereas the demonstration plot produced 15.90 t/ha. The 0.90-1.90 t/ha difference indicates potential improvement under more structured management, but it cannot be attributed solely to the biopesticide because the demonstration did not include a replicated control. The practice should therefore be validated through controlled trials, standardized input doses, and economic analysis before wider recommendation. Produktivitas kentang di Desa Bonto Marannu masih dibatasi oleh mutu benih, pengelolaan budidaya, dan tekanan organisme pengganggu tanaman. Penelitian ini mendeskripsikan teknik budidaya petani dan mengevaluasi hasil demonstrasi yang memperkenalkan perbaikan pengolahan lahan, pemilihan benih, pemupukan organik, serta pengendalian hama berbahan nabati. Penelitian menggunakan desain studi kasus deskriptif pada Juli-September 2024 dengan melibatkan 10 petani dari Kelompok Tani Hortikultura dan Gunung Loka. Data dikumpulkan melalui observasi lapangan, wawancara, kuesioner, dan dokumentasi, kemudian dianalisis secara deskriptif. Responden berumur 30-52 tahun, memiliki pengalaman bertani 8-20 tahun, dan mengelola lahan 0,7-3,0 ha. Praktik budidaya meliputi pembuatan bedengan, penanaman benih Granola dengan jarak 25 x 30 cm, pemupukan menggunakan pupuk kandang dan pupuk organik cair, pengendalian hama dengan biopestisida daun gamal, serta panen pada umur 90-100 hari setelah tanam. Produktivitas petani dilaporkan sekitar 14-15 ton/ha, sedangkan demonstrasi menghasilkan 15,90 ton/ha. Selisih 0,90-1,90 ton/ha menunjukkan potensi perbaikan melalui pengelolaan yang lebih terstruktur, tetapi belum dapat dikaitkan hanya dengan biopestisida karena demonstrasi tidak menggunakan kontrol dan ulangan eksperimental. Teknik tersebut perlu divalidasi melalui percobaan terkontrol, standardisasi dosis input, dan analisis ekonomi sebelum direkomendasikan secara luas.

Shallot farmers in Bonto Marannu apply diverse cultivation practices and still rely partly on synthetic inputs for pest and disease management. This study described farmer characteristics, cultivation practices, and the production achieved in a demonstration plot using gamal leaf biopesticide. The study was conducted from July to August 2024 using a descriptive case-study approach involving 12 farmers from the Montea and Sipassiriki farmer groups, six respondents from each group. Data were collected through observation, interviews, questionnaires, and documentation. Respondents had a mean age of 44.7 years, cultivated 2.51 ha on average, and had 17.9 years of farming experience. The main practices included a spacing of 15 × 20 cm, Phonska and urea fertilization, and chemical fungicide application for fungal disease control. Mean farmer production was 9.33 t/ha in Montea and 8.67 t/ha in Sipassiriki, whereas the demonstration plot produced 11.50 t/ha. The higher demonstration-plot yield is descriptive and cannot be attributed solely to gamal leaf biopesticide because the plot size, untreated control, and replication were not reported. The practice is nevertheless relevant as an environmentally friendlier component of integrated crop management, provided that formulation, dose, application frequency, and target pests are standardized. Petani bawang merah di Desa Bonto Marannu menerapkan teknik budidaya yang beragam dan masih menggunakan sebagian input sintetis untuk pengendalian hama dan penyakit. Penelitian ini mendeskripsikan karakteristik petani, teknik budidaya, serta hasil produksi pada demonstrasi plot yang menggunakan biopestisida daun gamal. Penelitian dilaksanakan pada Juli–Agustus 2024 menggunakan pendekatan studi kasus deskriptif terhadap 12 petani dari Kelompok Tani Montea dan Sipassiriki, masing-masing enam responden. Data dikumpulkan melalui observasi, wawancara, kuesioner, dan dokumentasi. Responden memiliki rata-rata umur 44,7 tahun, luas lahan 2,51 ha, dan pengalaman bertani 17,9 tahun. Teknik utama meliputi jarak tanam 15 × 20 cm, pemupukan Phonska dan urea, serta penggunaan fungisida kimia untuk pengendalian penyakit jamur. Rata-rata produksi petani mencapai 9,33 ton/ha pada Kelompok Tani Montea dan 8,67 ton/ha pada Kelompok Tani Sipassiriki, sedangkan demonstrasi plot menghasilkan 11,50 ton/ha. Hasil demonstrasi plot yang lebih tinggi bersifat deskriptif dan belum dapat dikaitkan hanya dengan biopestisida daun gamal karena ukuran plot, kontrol tanpa biopestisida, dan ulangan tidak dilaporkan. Biopestisida daun gamal tetap relevan sebagai komponen budidaya yang lebih ramah lingkungan apabila formulasi, dosis, frekuensi aplikasi, dan organisme sasaran distandardisasi.

Nutrient concentration is a major determinant of crop performance in nutrient film technique (NFT) hydroponics. This study evaluated the growth and productivity response of red lettuce (Lactuca sativa var. Red Rapid) to different AB Mix concentrations. The experiment was conducted in the greenhouse of the Universitas Bosowa Educational Garden, Bontoramba, Pallangga, Gowa, from 14 April to 23 May 2025. A randomized block design was used with five concentrations, namely 560, 630, 700, 770, and 840 ppm, and three replications. Plant height, number of leaves, leaf area, fresh weight, and root volume were observed. The response differed among traits. A concentration of 770 ppm produced the highest plant height at five weeks after planting (15.96 cm). A concentration of 840 ppm produced the highest fresh weight (57.11 g), root volume (30 mL), and leaf area (115.44 cm²). These results indicate that the concentration producing maximum vegetative height was not identical to that producing the greatest biomass and root development. For production-oriented cultivation, 840 ppm provided the strongest overall performance, whereas 770 ppm was most favorable for plant height. Konsentrasi larutan nutrisi merupakan faktor utama yang menentukan kinerja tanaman pada hidroponik Nutrient Film Technique (NFT). Penelitian ini bertujuan mengevaluasi respons pertumbuhan dan produktivitas selada merah (Lactuca sativa var. Red Rapid) terhadap berbagai konsentrasi pupuk AB Mix. Penelitian dilaksanakan di greenhouse Kebun Pendidikan Universitas Bosowa, Bontoramba, Pallangga, Gowa, pada 14 April–23 Mei 2025. Penelitian menggunakan rancangan acak kelompok dengan lima konsentrasi, yaitu 560, 630, 700, 770, dan 840 ppm, serta tiga ulangan. Parameter yang diamati meliputi tinggi tanaman, jumlah daun, luas daun, bobot basah, dan volume akar. Respons terbaik berbeda antarparameter. Konsentrasi 770 ppm menghasilkan tinggi tanaman tertinggi pada umur 5 MST, yaitu 15,96 cm. Konsentrasi 840 ppm menghasilkan bobot basah (57,11 g), volume akar (30 mL), dan luas daun (115,44 cm²) tertinggi. Hasil ini menunjukkan bahwa konsentrasi yang memaksimalkan tinggi tanaman tidak sama dengan konsentrasi yang menghasilkan biomassa dan perkembangan akar tertinggi. Untuk tujuan produksi, konsentrasi 840 ppm memberikan kinerja keseluruhan paling kuat, sedangkan 770 ppm paling mendukung pertumbuhan tinggi tanaman.

Fish-processing waste can be converted into liquid organic fertilizer (LOF), offering a potential nutrient source while reducing organic waste. This study evaluated the response of yardlong bean (Vigna sinensis L.) growth and yield to different concentrations of fish-waste LOF. The experiment was conducted at the Integrated Farming System Educational Garden of Universitas Bosowa using a randomized block design with four treatments, namely P0 (0 mL/L), P1 (50 mL/L), P2 (75 mL/L), and P3 (85 mL/L), and three replications. The recorded vegetative variables were plant height, number of leaves, stem diameter, and leaf width, whereas the generative variables were pod length, fresh pod weight, and number of pods. Based on the treatment means, P3 produced the greatest plant height (190.83 cm), stem diameter (4.38 mm), and fresh pod weight (531.40 g). P1 produced the highest number of leaves (64.30), leaf width (8.07 cm), and pod length (82.09 cm), while P2 produced the highest number of pods (11.87). Overall, concentrations of 75–85 mL/L provided the strongest yield response, although the best concentration differed among measured traits. Limbah pengolahan ikan dapat dimanfaatkan sebagai pupuk organik cair (POC), sehingga berpotensi menyediakan unsur hara sekaligus mengurangi limbah organik. Penelitian ini bertujuan mengevaluasi respons pertumbuhan dan hasil kacang panjang (Vigna sinensis L.) terhadap berbagai konsentrasi POC limbah ikan. Penelitian dilaksanakan di Kebun Pendidikan Integrated Farming System Universitas Bosowa menggunakan rancangan acak kelompok dengan empat perlakuan, yaitu P0 (0 mL/L), P1 (50 mL/L), P2 (75 mL/L), dan P3 (85 mL/L), serta tiga ulangan. Parameter vegetatif meliputi tinggi tanaman, jumlah daun, diameter batang, dan lebar daun, sedangkan parameter generatif meliputi panjang polong, berat segar polong, dan jumlah polong. Berdasarkan nilai rerata perlakuan, P3 menghasilkan tinggi tanaman (190,83 cm), diameter batang (4,38 mm), dan berat segar polong (531,40 g) tertinggi. P1 menghasilkan jumlah daun (64,30 helai), lebar daun (8,07 cm), dan panjang polong (82,09 cm) tertinggi, sedangkan P2 menghasilkan jumlah polong terbanyak (11,87 buah). Secara keseluruhan, konsentrasi 75–85 mL/L memberikan respons hasil paling kuat, meskipun konsentrasi terbaik berbeda antarparameter.
