Abstract

Sagu merupakan salah satu tanaman penghasil pangan yang potensial dimasa yang akan datang jika dikelola dengan baik. Pada kondisi alami sagu tumbuh menyebar pada berbagai ekosistem yang luas. Sagu memiliki daya adaptasi yang kuat dikarenakan dapat tumbuh pada lahan bercekaman tinggi bagi tumbuhan lain. Tanaman sagu menyebar luas mulai dari Kawasan pesisir, rawa mineral, Daerah Aliran Sungai, dataran menengah hingga dataran tinggi. Penelitian ini bertujuan untuk mengetahui karakteristik habitat berbagai aksesi sagu dan korelasinya terhadap produksi. Penelitian menggunakan metode observasi lapang dan pengujian dilaboratorium dengan analisis data kadar lengas dengan metode gravimetri, volume dengan metode ring sampel, berat jenis dengan prinsip hukum Archimedes, tekstur tanah dengan metode pipet serta analisis kimia tanah dengan pengujian di laboratorium. Koefisien korelasi menggunakan analisis korelasi Pearson untuk melihat hubungan antara kualitas tanah dengan dengan produksi sagu dengan taraf kepercayaan 95% dengan menggunakan perangkat lunak SPSS 26. Metode pengamatan hidrologi dengan mengukur tinggi muka air tanah dengan penggalian minipit dan tinggi genangan air pada daerah yang tergenang. Tipe habitat tumbuhan sagu di Tana Luwu sangat beragam ditemukan pada kondisi lahan pesisir, rawa mineral, daerah aliran sungai, dataran menengah hingga 1000 mpdl. Rata-rata produksi terendah yaitu 181.52 kg pati kering pohon-1 terdapat pada lokasi sampel rawa pesisir dengan lama genangan 3-6 bulan dengan ketinggian 10-80 cm diatas permukaan tanah saat musim hujan dan 0-40 cm dibawah permukaan tanah saat musim kemarau. Rawa pesisir tersebut dapat dikategorikan memiliki kelas hidrologi agak baik. Aksesi sagu menyebar tidak merata pada berbagai lingkungan tumbuhnya. Sago is one of the potential food-producing plants in the future if managed properly. Under natural conditions sago grows spread over a wide range of ecosystems. Sago has strong adaptability because it can grow in high stress areas for other plants. Sago plants spread widely from coastal areas, mineral swamps, watersheds, medium to highland areas. This study aims to determine the characteristics of the habitat of various sago accessions and their correlation to production. The study used field observation methods and laboratory testing with analysis of moisture content data using the gravimetric method, volume using the sample ring method, specific gravity using the principle of Archimedes' principle, soil texture using the pipette method and soil chemical analysis using laboratory testing. The correlation coefficient used Pearson's correlation analysis to see the relationship between soil quality and sago production with a 95% level of confidence using SPSS 26 software. The hydrological observation method was by measuring the height of the groundwater by digging a minipit and the height of the puddles in the inundated areas. Habitat types for sago plants in Tana Luwu are very diverse, found in coastal land conditions, mineral swamps, watersheds, medium plains up to 1000 meters above sea level. The lowest average production, namely 181.52 kg of tree-1 dry starch, was found in coastal swamp sample locations with an inundation period of 3-6 months with a height of 10-80 cm above ground level during the rainy season and 0-40 cm below ground level during the dry season. The coastal swamp can be categorized as having a rather good hydrological class. Sago accession is spread unevenly in various growing environments.

Abstract

Nitrogen adalah salah satu unsur hara untuk pertumbuhan tanaman, terutama kelapa sawit. Walaupun demikian, penggunaan pupuk nitrogen dari urea dapat menyebabkan kehilangan hara di tanah akibat dari pencucian, volatilisasi, dan imobilisasi oleh bahan organik tanah, sehingga akan mengurangi serapan hara tanaman. Asam humat dan inhibitor nitrogen adalah salah satu amelioran dalam meningkatkan ketersediaan nitrogen untuk diserap tanaman. Penelitian ini bertujuan untuk mengevaluasi penggunaan urea coating asam humat dan nitrogen inhibitor terhadap pertumbuhan, biomassa, dan efisiensi nitrogen bibit kelapa sawit fase pre nursery. Penelitian ini dilakukan di rumah kaca Pusat Penelitian Kelapa Sawit, Bogor. Rancangan perobaan yang digunakan adalah rancangan acak kelompok faktorial dengan tiga ulangan. Faktor pertama adalah jenis pupuk, yaitu a). urea, b) urea + asam humat, c). urea coating humat. Faktor kedua adalah inhibitor nitrogen, terdiri dari a). tanpa inhibitor,b). inhibitor urease, c). inhibitor nitrifikasi, d). inihibitor urease dan nitrifikasi. Hasil pada penelitian ini menunjukkan bahwa faktor jenis pupuk, yaitu penggunaan urea coating humat meningkatkan pertumbuhan vegetatif pada bibit kelapa sawit secara keseluruhan, yaitu tinggi tanaman, jumlah daun, diameter batang, luas daun, kandungan klorofil dengan nilai SPAD, panjang akar, volume akar, bobot basah tajuk dan akar, bobot kering akar, dan efisiensi penggunaan pupuk nitrogen, partial factor productivity, dan partial nutrient balance. Pada faktor inhibitor nitrogen, yaitu penggunaan inhibitor urease, hanya meningkatkan tinggi tanaman pada umur 4 BST. Kombinasi antara perlakuan urea coating humat dengan inhibitor urease meningkatkan tinggi tanaman umur 4 BST dan bobot kering akar.

Abstract

ABSTRAK Sebagai tahap awal dalam siklus hidup tanaman kelapa sawit (Elaeis guineensis Jacq.), praktik pembibitan kelapa sawit menjadi aspek penting yang memerlukan evaluasi lebih dalam. Pemahaman mengenai dampak lingkungan pada fase pembibitan adalah kunci untuk merancang strategi pengelolaan yang berkelanjutan, mengurangi kerusakan ekosistem, dan mencapai keseimbangan antara produksi dan konservasi alam. Penelitian ini bertujuan untuk menganalisis dampak lingkungan pembibitan kelapa sawit di Unit Pembibitan Kelapa Sawit (UPKS) Politeknik Negeri Lampung menggunakan pendekatan penilaian daur hidup atau life cycle assessment (LCA). Studi ini difokuskan pada penilaian daur hidup gate-to-gate yang dilaksanakan dari Oktober hingga Desember 2023. Data dikumpulkan melalui kunjungan lapang dan wawancara dengan pengelola UPKS. Ruang lingkup LCA dimulai dari penerimaan kecambah hingga bibit siap salur. Permodelan dampak lingkungan menggunakan openLCA versi 2.0.3 dengan metode CML-IA baseline dan database pendukung Agribalyse v3.0.1. Hasil penelitian menunjukkan bahwa secara umum pembibitan kelapa sawit memberikan dampak lingkungan yang tidak signifikan. Kontribusi dampak lingkungan terbesar berasal dari dampak sekunder, khususnya marine aquatic ecotoxicity sebesar 190.52122 kg 1,4-DB eq. dan abiotic depletion (fossil fuels) sebesar 5.65733 MJ. Dampak primer potensi global warming (GWP100a) sebesar 0.27033 kg CO2 eq. yang dominan berasal dari penggunaan polybag dan potensi human toxicity sebesar 0.08227 kg 1,4-DB eq. Upaya pengurangan dampak lingkungan dapat dilakukan dengan penggunaan pot tray yang dapat digunakan berulang kali atau alternatif polybag dari bahan organik, kombinasi pupuk anorganik dan pupuk organik untuk mengurangi dosis pupuk anorganik, dan mengurangi laju evapotranpirasi dari tanaman dan media tanam dengan penggunaan mulsa organik dan media tanam yang mengandung bahan organic. Kata kunci: dampak lingkungan, kelapa sawit, LCA, pemanasan global, pembibitan ABSTRACT As the initial stage in the oil palm (Elaeis guineensis Jacq.) plant life cycle, oil palm seedling cultivation becomes a crucial aspect that requires in-depth evaluation. Understanding the environmental impact at the seedling phase is critical to designing more sustainable management strategies, reducing ecosystem damage, and achieving a balance between production and conservation. This study aims to present an environmental impact analysis of oil palm seedling cultivation at the Oil Palm Nursery Unit (UPKS) of Politeknik Negeri Lampung using the life cycle assessment (LCA) approach. This study focuses on a gate-to-gate life cycle assessment conducted from October to December 2023. Data were collected through field visits and interviews with UPKS managers. The LCA scope covers from seed acceptance to ready-to-distribute seedlings. Environmental impact modeling used openLCA version 2.0.3 with the CML-IA baseline method and supporting database Agribalyse v3.0.1. Results indicate that oil palm seedling nursery generally has an insignificant environmental impact. The most substantial contributions come from secondary impacts, mainly marine aquatic ecotoxicity at 190.52122 kg 1,4-DB eq. and abiotic depletion (fossil fuels) at 5.65733 MJ. Primary impacts are potential global warming (GWP100a) at 0.27033 kg CO2 eq., primarily from polybag use, and potential human toxicity at 0.08227 kg 1,4-DB eq. Efforts to mitigate environmental impacts can be achieved by using reusable pot trays or organic material-based polybags as alternatives, coupled with a combination of inorganic and organic fertilizers to reduce the dosage of inorganic fertilizers. Additionally, curtailing evapotranspiration rates from plants and growing media can be accomplished by employing organic mulch and growing media enriched with organic matter. Keywords:  environmental impact, global warming, LCA, nursery, oil palm

Abstract

Pupuk bekas maggot (kasgot) adalah jenis pupuk organik yang dihasilkan dari proses pengomposan limbah organik menggunakan larva black soldier fly (Hermetia illucens). Penelitian ini bertujuan untuk mengetahui pengaruh pemberian kasgot terhadap pertumbuhan pakcoy. Penelitian dilakukan di Agribusiness and Technology Park (ATP) IPB University, Cikarawang, Bogor pada bulan Maret hingga April 2024. Penelitian menggunakan Rancangan Acak Lengkap dengan empat perlakuan dan lima ulangan, sehingga menghasilkan 20 satuan percobaan. Perlakuan yang diberikan adalah dosis kasgot dengan K0 (kontrol/tanpa pupuk maggot), K1 (pupuk maggot 100 g), K2 (pupuk maggot 200 g), dan K3 (pupuk maggot 100 g) per polibag ukuran 35 cm x 35 cm). Hasil penelitian menunjukkan bahwa pemberian kasgot dapat meningkatkan hasil dan morfologi tanaman pakcoy. Produksi dan morfologi tanaman pakcoy dibandingkan dengan tanaman kontrol. Berdasarkan hasil penelitian, peningkatan dosis pupuk dari 100 g per polibag hingga 300 g per polibag tidak memberikan perbedaan yang signifikan terhadap beberapa parameter pertumbuhan tanaman pakcoy, seperti tinggi tanaman, lebar daun, dan panjang akar. Tinggi tanaman berkisar antara 17.10 cm hingga 19.00 cm, lebar daun antara 5.12 cm hingga 6.22 cm, dan panjang akar antara 12.60 cm hingga 15.00 cm. Hal ini menunjukkan bahwa dosis pupuk sebesar 100 g per polibag sudah cukup untuk mendukung pertumbuhan optimal tanaman pakcoy, dan peningkatan dosis lebih lanjut tidak memberikan efek positif yang berarti.

Abstract

Nitrogen fertilization plays a crucial role in supporting plant growth. However, nitrogen in the soil can be lost through rainwater leaching. To address this issue, the concept of fertilizing N-stabilizer-coated urea was proposed. The aim is to reduce nitrogen loss on the field due to vaporization and minimize greenhouse gas (GHG) emissions. The study was conducted to assess the effectiveness of this N-stabilizer-coated urea in reducing nitrogen loss through vaporization, improving GHG emissions, and its impact on plant growth and leaf quality. The research was conducted at IPB-Cargill Jonggol, Bogor, West Java, oil palm education and research station from August 2021 to March 2022. The experimental design employed a completely randomized block design. The fertilizer treatments included four types of nitrogen fertilizers: urea (46% N), coated urea with N-stabilizer (46% N), ZA (21% N), and NPK (15-15-15, 15% N). Additionally, a control treatment without any fertilizer application was included. All treatments were replicated three times. Data analysis was done using the SAS (Statistical Analysis System) 9.0 program. The F-test was conducted, followed by DMRT (Duncan Multiple Range Test) advanced tests at a 5% error level. The results revealed that urea with N-stabilizer fertilization significantly reduced NH3-vaporization by 53% in the first week compared to the application of normal urea. NH3-vaporization level from ZA and NPK was < 1% compared to urea application. Field application of urea with N-stabilizer showed no significant difference in greenhouse gas emission (GHG) compared to the other nitrogen fertilizer types. The GHG values ranged from 7.10 to 7.29 g CO2-e.m-2 per day. The use of N-stabilizer-coated urea could be an effective approach to minimize nitrogen loss through vaporization and reduce greenhouse gas emissions while maintaining comparable results to other nitrogen fertilizer types in terms of GHG emissions on the field.

Abstract

Fly ash, a solid byproduct of coal combustion, contains both macro- and micronutrients that can function as soil conditioners. This study explores the sustainable use of fly ash in agricultural applications, specifically its role in improving acidic soils. The objective is to evaluate the potential of fly ash based on its chemical properties and agronomic advantages. A quantitative experimental design was applied, incorporating three levels of fly ash and two levels of manure fertilizer combinations, each with four replications plus a control group, resulting in a total of 24 experimental plants. The study assessed various parameters, including pakcoy (Brassica rapa L.) morphological traits (plant height, leaf count, root length, fresh and dry biomass), chemical characteristics of leachates (Ca²⁺, Na⁺, pH, TDS, and EC), photosynthetic performance, and statistical analysis. The results indicated that the treatment (A₂B₂) comprising 35% fly ash, 45% chicken manure, and 20% soil produced the optimal outcomes across all parameters. This treatment led to the best pakcoy growth, characterized by the highest number of leaves, greatest fresh and dry weights, and the longest root development. These findings highlight that fly ash offers a sustainable and effective solution for soil amendment, enhancing agricultural productivity on pakcoy plant by improving soil quality while simultaneously contributing to industrial waste management.

Abstract

Biochar and liquid organic fertilizer (POC) can be combined to enhance plant growth. This study aimed to evaluate the effects of applying sugarcane bagasse biochar and water hyacinth liquid organic fertilizer (POC) on soil properties and the growth of vegetable crops, particularly pakcoy (Brassica rapa L.) and spinach (Amaranthus sp.). Initial soil analysis showed a pH of 6.97 with high levels of potassium (K) and nitrate (NO₃⁻). The biochar used had an alkaline pH of 8.83, a fixed carbon content of 63.2%, and was classified as grade A according to the Indonesian Ministry of Agriculture standards. Meanwhile, the water hyacinth POC had an acidic pH of 4.02 with a high nitrate content (6,700 ppm). Observations indicated that biochar application up to 20 tons/ha increased the number of leaves, leaf area, and dry weight of pakcoy, while higher doses tended to reduce growth. Application of water hyacinth POC significantly increased the fresh weight of spinach compared to the control. The combination of biochar and POC demonstrated great potential in improving soil fertility and enhancing vegetable crop yields. This study recommends the use of biochar and POC at appropriate dosages to support sustainable agriculture on Andosol soils.

Abstract

Tana Luwu area owns a relatively high diversity and production potential of sago, but it has not yet been managed optimally. This study aims to identify and analyze the diversity of morphological characteristics and the production of various sago accessions in Tana Luwu. Based on morphological characteristics, the sago palm in Tana Luwu is divided into two groups by the presence of thorns on the rachis and petioles. The presence of thorns has the largest coordinate axis angles, representing a higher diversity distance than other morphological characteristics. Some accessions show very high production potential, with a total production of 476.66 kg per dry tree starch. The average sago production in the six accessions is 276.40 kg per dry tree starch. Accessions with a yield potential > 200 kg per dry starch are observed in Kapa, Uso, Kasimpo, and Sabbe. Therefore, sago in these accessions is potentially developed to obtain superior varieties. Two significant morphological characteristics that contribute to sago production are stem height (r = 0.73) and the number of leaves (r = 0.78).

Abstract

Photosynthesis rate plays a significant role in plant growth and development. A study was conducted to determine the best methods to grow sago planting materials from sago suckers. Photosynthesis rate, stomatal density, intercellular CO2 concentration, stomatal conductance, transpiration, sugar and starch content of the sago leaves from different methods of planting was determined. The field experiment was carried out at the Cikabayan Experimental Station from January 2020 to February 2021; the leaf morphology was conducted at the Microtechnical Laboratory and Testing Laboratory of the Department of Agronomy and Horticulture, Faculty of Agriculture, IPB University, Bogor, Indonesia. The treatments for the sago seedlings were immersion of the bare-rooted seedlings in water, immersion in water with media mix in polybags, transplanted to media mix in polybags, and immersion of bare-rooted seedlings for 4 weeks in water followed by transplanting to media mix in polybags. The study was arranged using a single factor a completely randomized block design, and quantitative data was analyzed using Microsoft Excel 2013 and the SAS. Stomatal density and photosynthetic rate were not significantly different between treatments. In contrast, the sugar content of immersed seedling without polybags for one month followed by transplanting to polybag had the best growth compared to those from other treatments, both at the nursery phase and post-transplanting phase. All planting methods resulted in good quality planting materials. At the nursery phase, sago seedlings immersed in water method grew the best; at the post-transplanting phases seedlings immersed bare-rooted for one month followed by transplanting to polybags grew better than those with other treatments
