Intensive tillage will continuously reduce soil quality, characterized by decreased soil organic-C. Low soil organic-C indicates the disturbance of soil fertility. More conservative soil management experiments have been done for seven years to restore the soil quality for sugarcane (Saccharum officinarum L.) productivity. This research aimed to study the effect of the tillage system, bagasse mulch, and their interactions on soil chemical properties and sugarcane agronomic response. The research was conducted on a Split Plot of five groups. The main plot was the tillage system consisting of intensive tillage and no-tillage, while the subplot was the bagasse mulch consisting of bagasse mulch and no-bagasse mulch. This study found that in sugarcane cultivation, no-tillage system was beneficial for soil P-available, sugarcane length, and sugarcane ripening; bagasse mulch was beneficial for soil organic-C and also soil P-available. The no-tillage system to increase P-available can be combined with bagasse mulch or no-bagasse mulch, but the no-tillage system combined with no-bagasse mulch increases the percentage of gap in sugarcane cultivation.

Sugarcane (Saccharum officinarum L.) is a plant that is cultivated to be processed into sugar. However, until now Indonesia has become a sugar importing country because the sugar industry is unable to meet the needs and demand for sugar which continues to increase as well as the high domestic selling price, so that it is necessary to import sugar to meet the demand for sugar in Indonesia. To overcome this is to apply Nitrogen fertilization on sugarcane combined with a companion material in the form of Zeolite. This study aims to obtain the growth and yield of ratoon 2 sugarcane plants by administering Zeolite and the proportion of N fertilizer as well as the interaction between the Zeolite and the proportion of N fertilizer. This study used a Randomized Block Design (RAK) Arranged in a split plot with two treatment factors repeated 3 times with 6 treatment combinations to obtain 18 experimental units. The main plot of Zeolite dosing with Z₀ is without zeolite and Z₁ is 700 kg.ha⁻¹ (equivalent to 0.8 kg.8m kairan⁻¹). Subplot dosage proportions of N fertilizer with P₁ is 100% urea (equivalent to 0.36 kg. 8m caustic⁻¹), P₂ is 80% urea (equivalent to 0.28 kg. 8m caustic⁻¹), and P₃ is 60% urea (equivalent to 0.21 kg. 8m caustic⁻¹). The results of this study indicate that the dose of Zeolite has an effect on all variable parameters of growth observations which include plant height, stem diameter, and number of internodes. As well as plant yields which include stem weight, stem length, brix value and yield. Application of [dose percentage of N fertilizer did not affect the growth and yield of sugarcane plants. There was no interaction between the Zeolite dosage and the proportion of N fertilizer doses on the growth and yield of sugarcane

Desa Wiyono merupakan salah satu desa yang terletak di Kecamatan Gedong Tataan, Kabupaten Pesawaran. Mayoritas penduduk desa Wiyono (70% dari seluruh tenaga kerja) memiliki mata pencaharian sebagai petani. Menurut BPS Pesawaran (2022), produksi kelapa di Kabupaten Pasawaran mencapai 8.121 ton/tahun dengan luas areal 11.238 ha. Tanaman kelapa (Cocos nucifera L) adalah tanaman multifungsi yang seluruh bagiannya memiliki manfaat untuk manusia. Nata de coco adalah suatu produk hasil fermentasi oleh bakteri acetobacter xylinum. Produk ini berbentuk padat, kokoh, kuat, putih, transparan, kenyal dan banyak digunakan sebagai salah satu pangan fungsional karena mengandung serat pangan. Saat ini petani mengalami kesulitan dalam mengolah air kelapa menjadi nata de coco karena ketidaktahuan ilmu pengetahuan dan teknologi yang digunakan, sehingga air kelapa yang dihasilkan hanya dibuang begitu saja sebagai limbah. Kondisi seperti ini tentunya membutuhkan transfer ilmu pengetahuan dan bimbingan dari berbagai pihak. Tim pengusul kegiatan telah merancang metode kegiatan yang diterapkan melalui penyuluhan, demonstrasi, pelatihan, konsultasi, dan bimbingan, serta evaluasi. Setelah program dilakukan diperoleh hasil bahwa pemahaman dan pengembangan teknis teknologi masyarakat meningkat dari 0% menjadi 100% dan penerapan hasil di lapangan sebesar 15%. Dengan dilakukannya transfer ilmu pengetahuan dan teknologi kepada masyarakat khususnya kelompok wanita tani Desa Wiyono, diharapkan air kelapa yang sebelumnya tidak bernilai menjadi memiliki nilai ekonomi yang cukup tinggi.

Bud sett is one type of sugarcane planting material that is efficient in terms of size, allowing the distribution process in large quantities from variety producers to users. However, its smaller size than mule-shaped planting material will cause the freshness of bud sett planting material to decrease more quickly during storage due to the delayed planting period. The purpose of this study was to determine the impact of delayed planting at various storage periods of bud sett sugarcane seeds on the initial growth and production of sugarcane seeds. This study used a Randomized Block Design with 3 replications. The treatment of delayed planting period was 5 levels, namely without storage period (T0), storage period 1 x 24 hours (T1), storage period 2 x 24 hours (T2), storage period 3 x 24 hours (T3) and storage period 4 x 24 hours jam (T4). The data were analyzed variously and tested for the mean value using the Least Significant Difference (LSD) test at the 5% level. The results showed that the weight and germination of bud setts decreased with increasing length of the delayed planting period. In general, the storage period for bud sett seeds does not have a significant effect on seedling growth and seedling production.

Petroleum industrial activities have the potential to alter soil physical and chemical properties through various contamination mechanisms and operational processes. This research aimed to evaluate the impact of PT Pertamina EP Cepu petroleum industrial activities on basic physical and chemical soil properties in areas surrounding operations. The study was conducted from October to November 2025 using a descriptive survey approach with purposive sampling method. Soil samples were collected at 0-20 cm depth from 12 sampling points located within a ± 200-meter radius in four cardinal directions (North, East, South, and West) from the operational center. Physical properties analyzed included soil texture, bulk density, and porosity, while chemical properties included pH, C-Organic, total N, available P, exchangeable K, and electrical conductivity (EC). Data analysis was performed descriptively by comparing laboratory measurement results with soil property assessment criteria established by Balai Penelitian Tanah to categorize each parameter and identify soil quality degradation levels in the research area. The results showed that soil in the research area had clay texture (67% clay fraction), high bulk density (1.47 ± 0.21 g/cm³), moderate porosity (44.5%), neutral pH (6.7 ± 0.2), very low C-Organic (0.99 ± 0.07%) and total N (0.07 ± 0.01%), high available P (28.64 ± 2.22 mg/kg) and exchangeable K (0.94 cmol(+)/kg), and moderately high EC (3.9 dS/m). These findings indicate that petroleum operational activities have caused soil quality degradation, particularly through soil compaction and reduction in organic matter content. Appropriate soil management interventions, including organic matter addition, traffic management, and contamination remediation, are essential to restore and maintain soil quality in petroleum operational areas.

Praktik pengolahan tanah dan pemupukan jangka panjang merupakan bagian kegiatan budidaya tanaman yang mempengaruhi secara langsung kesuburan tanah. Pemilihan tidak tepat metode praktik dapat menyebabkan penurunan kesuburan tanah, akibat penipisan kandungan bahan organik tanah, erosi, atau akibat leaching dan memicu terjadinya degradasi tanah. Masa bera adalah fase istirahat tanah yang bertujuan untuk peningkatan dan pemulihan kesuburan tanah secara alami. Tujuan penelitian yaitu untuk mengkaji karakteristik beberapa sifat kimia Ultisol akibat masa bera pada sistem olah tanah dan pemupukan nitrogen jangka panjang (tahun tanam ke-37). Tempat pelaksanaan penelitian adalah lahan percobaan tanpa olah tanah jangka panjang Polinela dan Laboratorium Ilmu Tanah FP Unila. Penelitian dirancang dengan RAK 2 faktor dan 4 ulangan yaitu praktik olah tanah jangka panjang (T1 = olah tanah intensif, T2 = olah tanah minimum, dan T3 = tanpa olah tanah) dan pemupukan N jangka panjang (N0 = tanpa pupuk N dan N2 = pemupukan N 200 kg ha-1. Hasil penelitian menunjukkan bahwa masa bera mampu meningkatkan pH tanah dan C-organik untuk semua perlakuan. Masa bera meningkatkan KTK tanah pada perlakuan pemupukan N jangka panjang. Praktik olah tanah dan pemupukan N jangka panjang sebagai faktor tunggal memberikan pengaruh signifikan terhadap pH tanah setelah masa bera dengan nilai pH tanah tertinggi pada perlakuan OTI dan pemupukan N jangka panjang.
