https://jurnal.fp.unila.ac.id/index.php/JA/article/view/9668
<em>Sago productivity is still low because the sago population is generally still forested and the types of sago in one area still vary. One of the largest sago-producing areas in the past was South Sulawesi Province, with the center of sago distribution in Tana Luwu. The research aims to determine sago characteristics and obtain superior types of sago in North Luwu Regency, South Sulawesi Province. The research was carried out by observing sago populations, characterizing morphology, and measuring starch production., Observation results found two types of sago, namely thornless and thorny. The kind of sago most widely distributed and used is sago thornless. The results of morphological characterization and measurement of sago starch production showed an average </em><em>length of stem free of leaves</em><em> of 14 m (±3.07), lower stem circumference of 162 cm (±12.40), wet starch production of 1,110 kg (± 397) per tree, and dry starch production 598 kg (+ 178) per tree. The selection criteria for Tana Luwu sago as a source of sago seeds are based on the characteristics of length of stem free of leaves > 12 m and rootstock circumference >150 cm. The potential for seed production is 94,000 seedlings which can be used for sago development.</em>Alfred Pahala Manambangtua, Meity Tulalo, Jeanette Kumaunang, Hengky Novarianto, Steivie Karouw, Asthutiirundu Asthutiirundu, Yulianus Matana, Engelbert Manaroinsong, Muhammad Nur, Ismail Maskromo

https://jurnal.fp.unila.ac.id/index.php/JA/article/view/9005
<p>Krokot (<em>Portulaca oleracea</em> L.) merupakan gulma potensial yang memiliki banyak manfaat, khususnya sebagai sumber pangan dan tanaman obat, sehingga berpeluang dikembangkan sebagai komoditas alternatif. Namun, pemanfaatan dan pembudidayaan krokot masih belum dilakukan secara optimal. Oleh karena itu, diperlukan penelitian mengenai teknik budidaya yang tepat agar produksi krokot dapat berkelanjutan, aman dikonsumsi, dan berkualitas. Budidaya intensif dapat dilakukan melalui pengaturan suhu, intensitas cahaya, kelembapan, kondisi tanah, dan ketersediaan nutrisi. Penelitian dilaksanakan di Tanggung, Kecamatan Kepanjenkidul, Kota Blitar, Jawa Timur pada September hingga November 2023. Penelitian menggunakan metode eksperimental dengan Rancangan Petak Terbagi dalam Rancangan Acak Kelompok (RAK) yang terdiri atas dua faktor. Faktor pertama (<em>main plot</em>) yaitu intensitas cahaya yang terdiri atas naungan 0% (kontrol/N0), naungan 50% (N1) dan naungan 75% (N2). Faktor kedua (<em>sub plot</em>) yaitu dosis pupuk kandang kambing (P) yang terdiri atas 0 g/polibag (kontrol/P0), 40 g/polibag (P1), 60 g/polibag (P2) dan 80 g/polibag (P3). Parameter yang diukur selama pengamatan yaitu waktu muncul tunas, jumlah daun, jumlah cabang, diameter tajuk, waktu muncul bunga, bobot basah tanaman, dan kandungan klorofil. Hasil penelitian menunjukkan bahwa kombinasi tanpa naungan dan dosis pupuk kandang kambing 60 g/polibag merupakan perlakuan efektif untuk mendukung pertumbuhan dan hasil krokot. Perlakuan naungan 0% secara tunggal mampu memengaruhi jumlah daun, jumlah cabang, diameter tajuk, waktu muncul bunga dan bobot basah tanaman. Perlakuan dosis pupuk kandang kambing 60 g/polibag secara tunggal mampu memengaruhi seluruh parameter pengamatan.</p>Felicitas Deru Dewanti, Aufa Aptana Amalia Arif, Yonny Koentjoro

https://jurnal.fp.unila.ac.id/index.php/JA/article/view/10323
<p>Meningkatnya kesejahteraan hidup masyarakat memerlukan kualitas sayur dengan kandungan gizi yang lebih tinggi yaitu mengandung lebih banyak antioksidan, vitamin, dan mineral. Pemanfaatan cahaya buatan seperti spektrum merah dan biru dapat meningkatkan kandungan gizi sayuran pada selada keriting maupun tanaman lainnya. Tanaman muda mengandung gizi lebih baik dibanding tanaman dewasa, oleh karena itu perlu diteliti perlakuan kombinasi kedua faktor tersebut. Tujuan penelitian ini adalah mengkaji pengaruh cahaya LED dan umur panen terhadap kandungan klorofil, vitamin C, dan antioksidan selada keriting di plant factory. Penelitian ini menggunakan Rancangan Acak Lengkap faktorial dengan dua faktor, yaitu faktor I adalah empat taraf cahaya LED yaitu P (putih), M (merah), B (biru), dan MB (merah-biru) dan faktor II adalah umur panen yaitu U 14 (14 hst) dan U 40 (40 hst). Semua perlakuan diulang empat kali. Warna cahaya merah-biru dan umur panen 40 hst berinteraksi secara signifikan dan memberikan jumlah klorofil tertinggi di antara semua perlakuan yaitu sebesar 29,38 SPAD. Kombinasi perlakuan cahaya biru dan umur panen 40 hst memberikan daya antioksidan terbesar yaitu 94,88 mg/g dan kandungan vitamin C tertinggi yaitu 168,10 mg/g pada selada keriting.</p>I Gusti Made Kusuma Ardana, I Ketut Suada, rindang dwiyani

https://jurnal.fp.unila.ac.id/index.php/JA/article/view/12611
<p>Jambu air menjadi buah favorit karena bentuknya yang unik serta tekstur renyahnya, terutama pada varietas Citra dan Madu Deli. Tanaman ini diperbanyak secara vegetatif dengan teknik setek. Studi ini bertujuan untuk mengevaluasi pengaruh varietas jambu air serta durasi perendaman dalam larutan IBA dan NAA terhadap tingkat keberhasilan perakaran setek. Studi ini dijalankan pada periode Maret hingga Juni 2024 di rumah kaca Laboratorium Lapangan Terpadu, Universitas Lampung. Desain percobaan yang diterapkan adalah rancangan acak kelompok (RAK) dengan tiga kali ulangan. Percobaan mencakup dua faktor perlakuan (2x4), yaitu faktor pertama berupa varietas jambu air (Citra/K<sub>1</sub> dan Madu Deli/K<sub>2</sub>), serta faktor kedua berupa perlakuan perendaman, yang mencakup perlakuan tanpa perendaman (B<sub>0</sub>), serta perendaman selama 60 menit (B<sub>1</sub>), 120 menit (B<sub>2</sub>), dan 180 menit (B<sub>3</sub>). Uji homogenitas ragam data dijalankan menggunakan uji Bartlett, sementara uji aditivitas dijalankan dengan uji Tukey, dan untuk melihat perbedaan antar perlakuan, dijalankan analisis ragam (uji-F) dengan uji ortogonal polinomial. Temuan studi mengindikasi tidak terdapat perbedaan yang signifikan antara varietas Citra dan Madu Deli dalam keberhasilan perakaran setek. Perendaman selama 180 menit memberikan hasil terbaik dengan kenaikan persentase akar, panjang akar, sebaran akar, persentase tunas, dan jumlah daun. Di sisi lain, perendaman selama 120 menit lebih efektif dalam meningkatkan jumlah akar dan tunas pada setek jambu air, serta mengindikasi adanya interaksi antara varietas dan durasi perendaman auksin dalam peningkatan jumlah daun.</p>RA Diana Widyastuti, Alika Fadhilah Manaf, Rugayah, Yusnita Yusnita

https://jurnal.fp.unila.ac.id/index.php/JA/article/view/13214
<p>Tanah Ultisol umumnya dicirikan oleh kesuburan yang rendah, kandungan bahan organik yang terbatas, reaksi tanah yang masam, serta tingkat kejenuhan aluminium (Al) dan besi (Fe) yang relatif tinggi. Pada kondisi masam, oksida Al dan Fe memiliki dominasi muatan positif yang lebih besar sehingga meningkatkan kemampuan tanah dalam mengadsorpsi fosfor (P). Tingginya adsorpsi P tersebut menyebabkan ketersediaan fosfor bagi tanaman menjadi terbatas. Suatu upaya menurunkan jerapan P tanah dan meningkatkan P terpanen tanaman yaitu intensifikasi lahan dan pemupukan baik secara organik maupun anorganik. Tujuan penelitian ini adalah menganalisis pengaruh olah tanah dan pemupukan terhadap jerapan fosfor, jumlah fosfor terpanen dan korelasi antara jerapan fosfor dengan fosfor terpanen tanaman edamame. Penelitian ini mengimplementasikan Rancangan Acak Kelompok (RAK) faktorial dengan dua perlakuan: olah tanah minim (T0) dan olah tanah intensif (T1), serta dua jenis pemupukan: tanpa pupuk (P0) dan kombinasi pupuk NPK 200 kg ha⁻¹ serta pupuk kandang ayam 1 Mg ha⁻¹ (P1). Setiap perlakuan diulang empat kali. Masing-masing dari perlakuan diulang empat kali. Hasil menunjukkan bahwa perlakuan olah tanah minimum mampu menurunkan jerapan maksimum P (X<sub>max</sub>), namun tidak berpengaruh nyata terhadap P-terpanen dan biomassa kering tanaman edamame. Sedangkan, pemberian pupuk NPK 200 kg ha<sup>-1</sup> dan pupuk kandang ayam 1000 kg ha<sup>-1</sup> mampu menurunkan jerapan maksimum P (X<sub>max</sub>) dan berpengaruh nyata terhadap P-terpanen dan biomassa kering tanaman edamame. Selain itu, jerapan maksimum P (X<sub>max</sub>) menunjukkan korelasi negatif terhadap P-tersedia dan P-potensial.</p>Septi Nurul Aini, Amalia Hayati, Nur Afni Afrianti, Supriatin Supriatin

https://jurnal.fp.unila.ac.id/index.php/JA/article/view/8483
Generative propagation was a form of propagation that coffee growers have so far utilized most frequently. Seed dormancy is a common issue in the production of generative coffee. The length of the germination process undoubtedly affects the quantity of seeds available, hence ZPT soaking is required to get around it. a few the crops that can be utilized a source of the hormone gibberellin is the water hyacinth. The goal of this study was to find a therapy that would effectively break the dormancy of Liberika coffee seeds by soaking coffee seeds in water hyacinth extract. P0 = Soaking with water for 24 hours (control), P1 = Soaking with water hyacinth root extract for 12 hours, P2 = Soaking with water hyacinth root extract for 24 hours, and P3 = Soaking with water hyacinth root extract for 36 hours. The research was carried out using a design that was completely randomized. The findings indicated that the length of time liberica coffee seeds were soaked in water hyacinth extract have a substantial impact on breaking the dormancy of coffee seeds, as measured by the percentage of time that sprouts appeared and the percentage of time that cotyledons ruptured, as well as germination power and speed. Coffee seeds should be soaked in water hyacinth extract for least 24 hours for the most effective results<em>.</em>Elza Zuhry, Rini Desvayona, Yunandra Yunandra

https://jurnal.fp.unila.ac.id/index.php/JA/article/view/11852
<p>Soybean (<em>Glycine max</em> L.) is an important commodity in supporting national food security. However, its productivity in Indonesia, especially in the ultisol lands of Southeast Sulawesi, is still low due to limited soil fertility and bacterial pustule disease attacks. This study aims to determine the effectiveness of the combination of Biofresh plus biofertilizer and NPK inorganic fertilizer doses in suppressing the intensity of bacterial pustule disease in several soybean varieties on ultisol soil. The study applied a split plot design within a BRD framework, consisting of 16 treatment combinations and replications three times. The variables measured included disease severity, area under the disease development curve (AUDPC), and the level of effectiveness of disease control. The results showed that the Dena-1 (F4) variety was the most resistant to bacterial pustule, with the lowest AUDPC (247.80%-day) and the lowest disease severity at all stages. The combination of Biofresh plus with or without low NPK (25–50%), is more effective in suppressing disease than full inorganic fertilizer, with the highest effectiveness of 32.91% (F1R2). Control effectiveness is highly dependent on the combination of varieties and fertilizers, where F4 is most effective with R1, F1 with R2, and F3 with R3.</p>Anwar Anwar, Andi Khaeruni Andi Khaeruni, Vit Neru Satrah vit

Penelitian ini bertujuan mengevaluasi pengaruh berbagai jenis pupuk kandang dan model simpul stek terhadap pertumbuhan dan hasil ubi jalar. Penelitian dilaksanakan di Desa Rompegading, Kecamatan Cenrana, Kabupaten Maros, Sulawesi Selatan, pada April–Desember 2023 menggunakan Rancangan Acak Kelompok (RAK) faktorial dengan dua faktor. Faktor pertama terdiri atas tanpa pupuk kandang, pupuk kandang sapi, kambing, dan itik, sedangkan faktor kedua meliputi model simpul stek berbentuk angka 8, huruf Q, dan huruf J. Parameter yang diamati meliputi panjang cabang, jumlah daun, bobot tajuk per tanaman, jumlah umbi per tanaman, dan bobot umbi per tanaman. Hasil penelitian menunjukkan bahwa jenis pupuk kandang maupun model simpul stek tidak berpengaruh nyata terhadap seluruh parameter pengamatan. Meskipun demikian, kombinasi pupuk kandang kambing dan model simpul stek huruf Q menghasilkan nilai rata-rata tertinggi pada seluruh parameter pertumbuhan dan hasil, dengan bobot umbi mencapai 1,90 kg tanaman⁻¹ atau setara dengan produktivitas sekitar 47,5 t ha⁻¹. Kombinasi perlakuan tersebut berpotensi diterapkan sebagai teknologi budidaya ubi jalar berbasis kearifan lokal.</p>Haerul - Haerul

https://jurnal.fp.unila.ac.id/index.php/JA/article/view/10361
<p><em>Indonesia is a world’s largest rubber plantation area, but it is contrary with the productivity. One aspect of cultivation that causes a decrease in rubber productivity is competition with weeds, therefore the utilization of a chemical herbicide (metsulfuron-methyl 20%) has the effective potentially to controlling weeds in rubber plantations. This study aimed to evaluate the vegetation and composition of weeds, obtain the dose of metsulfuron-methyl 20% herbicide which is effective and efficient in controlling weeds in immature smallholder rubber plantations, and aware the phytotoxicity of rubber trees due to the application of it. The present research was conducted at the smallholder rubber plantation located in Ampek Koto, Pulau Punjung District, Dharmasraya and the Laboratory of Andalas University 3<sup>rd</sup> Campus, Dharmasraya. This research was designed based on a Randomized Block Design (RBD) with seven treatments were repeated four times, i.e., metsulfuron-methyl 20% herbicide at 37,5; 50; 62,5; 75; 87,5 g/ha, manually weeding, and control plot. The observations data were analysis of variance and it was continued by Duncan’s Multiple Range Test (DMRT) at 5% significance level. The results showed that there were five weed species that dominated in the immature rubber plantations, and metsulfuron-methyl 20% herbicide had an effect on two species of weeds, i.e. Borreria latifolia and Clidemia hirta, with a more effective and efficient dose of 37,5 g/ha. The results of phytotoxicity observations on immature rubber trees showed no symptoms due to application of metsulfuron-methyl 20% herbicide. It is can be as a consideration for farmers and stakeholder in using this herbicide, thus impact on supporting sustainable agriculture because the recommended herbicide dose is the lowest one.</em></p>Wulan Kumala Sari

https://jurnal.fp.unila.ac.id/index.php/JA/article/view/9407
<p>Penelitian yang dilaksanakan bertujuan untuk mengetahui pengaruh aplikasi pupuk cair terhadap hasil beberapa klon tanaman ubi kayu. Penelitian berlangsung pada bulan Juli 2023 - Mei 2024 di Kebun Pendidikan dan Pengembangan Pertanian, Fakultas Pertanian, Universitas Tidar, Desa Sidorejo, Kecamatan Bandongan, Kabupaten Magelang. Metode penelitian yang digunakan yaitu percobaan faktorial yang disusun menggunakan rancangan split-plot dengan petak utama berupa macam klon dan anak petak berupa jenis pupuk. Terdapat dua faktor perlakuan pada penelitian ini, Faktor pertama yaitu macam klon yang terdiri dari Ketan, Mentega, Klenteng dan Rengganis. Faktor kedua berupa pupuk cair yang terdiri dari pupuk limbah Rumah Pemotongan Hewan (RPH) dan pupuk nano nutrien. Data dianalisis menggunakan sidik ragam kemudian dilakukan uji lanjut dengan uji BNT taraf 1 % dan 5 %. Hasil penelitian menunjukkan bahwa klon rengganis memberikan rerata paling tinggi parameter jumlah umbi, panjang umbi terpanjang, berat segar umbi dan kadar pati. Aplikasi pupuk nano nutrien menghasilkan kadar protein umbi tertinggi.</p>Siti Nurul Iftitah

https://jurnal.fp.unila.ac.id/index.php/JA/article/view/11768
<p><em>This study aimed to evaluate the effects of ZnSO₄ application on biomass accumulation, grain yield, and Zn content in three rice varieties. The research was conducted in paddy fields located in Maja Village, Margapunduh Subdistrict, Pesawaran District, Lampung. The treatments were arranged in a factorial design using a strip plot with three replications. The treatments were arranged by a factorial design (4×3) using a strip plot in a completely randomized block design (CRBD) with three replications. The first factors were four application methods of ZnSO₄, consisting of: control (P0), seed priming with 0.25% ZnSO₄ (P1), seed priming with 0.25% ZnSO₄ and foliar spray with 0.5% ZnSO₄ at the vegetative stage (P2), seed priming with 0.25% ZnSO₄ and foliar spray with 0.5% ZnSO₄ at the generative stage (P3), and seed priming with 0.25% ZnSO₄ and foliar spray with 0.5% ZnSO₄ at both vegetative and generative stages (P4). The second factors were three rice varieties, consisting of Ciherang (V1), Inpari-32 (V2), and Inpari IR Nutrizinc (V3). The observed variables included fresh and dry biomass at vegetative and harvest stages, weight of 100 grains, harvest index, and milled dry grain. The results showed that the combination of ZnSO₄ seed priming and foliar spray at both vegetative and generative stages significantly increased biomass accumulation, grain yield, and Zn content. Ciherang and Inpari-32 varieties produced higher yields compared to Inpari IR Nutrizinc. This study indicates that agronomic biofortification through ZnSO₄ application is effective in improving rice yield and nutritional quality, particularly Zn content, which plays a vital role in addressing stunting.</em></p>Dytri Anintyas Putri, Muhammad Kamal, Eko Pramono, Muhammad Syamsoel Hadi, Agus Karyanto
