Abstract

This study aims to disseminate the soil fertility status of two types of agricultural land, namely shallot cultivation land in Doulu Village, Berastagi District, Karo Regency, and rice field land in Nalela Village, Porsea District, Toba Samosir Regency, North Sumatra Province. The research methods used include field surveys, random soil sampling, and laboratory analysis of soil physical and chemical properties, including pH, cation exchange capacity (CEC), base saturation (KB), organic C content, nitrogen (N), phosphorus (P), potassium (K), and other nutrients such as calcium (Ca) and magnesium (Mg). The results showed that the analysis of shallot land in Doulu Village had a moderate to low level, due to acidic pH, low levels of organic matter, nitrogen, and phosphorus, and suboptimal cation exchange capacity. Meanwhile, rice fields in Nalela Village showed very acidic pH, low to very low quality CEC and organic C, and low phosphorus and potassium content. Based on the land suitability evaluation, agricultural land in both areas is categorized in class S2 (quite suitable) to S3 (marginally suitable), which indicates the need for land management intervention. This study recommends the application of balanced fertilization, addition of organic matter, improvement of soil pH, and erosion management to improve soil fertility status and support the sustainability of agricultural production in both villages.

Abstract

This study aims to compare the primary metabolite content of yellow Kepok banana (Musa paradisiaca L.) leaves obtained through tissue culture and conventional cultivation methods. Yellow Kepok banana is one of Indonesia’s superior varieties with high economic value and great potential as a raw material for the food industry and as a source of value-added biomass. In the context of agricultural biotechnology, tissue culture techniques not only enable rapid and uniform plant propagation but may also influence the biochemical composition of plants through more controlled growth conditions. This study employed a descriptive experimental design with two treatments and three replications. Primary metabolites analyzed included carbohydrates, proteins, fats, crude fiber, ash, and moisture content, using the proximate (AOAC) method. The results showed that leaves derived from tissue culture had higher levels of carbohydrates (44.15% DM), proteins (19.77% DM), and fats (7.82% DM) compared to conventionally grown plants (39.93% DM; 16.13% DM; 6.20% DM). Conversely, conventionally grown leaves contained higher crude fiber, ash, and moisture. Controlled tissue culture conditions enhanced physiological efficiency and energy metabolite accumulation, whereas natural environments favored structural component formation. These findings highlight the potential of tissue culture as an effective method for producing banana leaf biomass with improved nutritional and metabolite profiles.

Abstract

Kebijakan pemerintah menerapkan industri energi terbaharukan dari minyak sawit memberi peluang penyediaan bahan tanaman dalam jumlah yang sangat besar untuk memenuhi kebutuhan perluasan areal kelapa sawit. Harga pupuk yang terus meningkat setiap tahun menjadi masalah bagi produsen penyedia bibit kelapa sawit. Penggunaan pupuk organik cair (POC) dari limbah pabrik kelapa sawt dan pupuk hayati Biofertilizer merupakan salah satu alternatif untuk mengurangi ketergantungan akan pupuk anorganik yang selama ini digunakan di pembibitan kelapa sawit. Hasil penelitian menunjukkan bahwa pemberiaan pupuk organik cair pada bibit kelapa sawit dan pupuk haya biofertilizer nyata menghasilkan pertumbuhan bibit kelapa sawit di main nursery dibandingkan dengan penggunaan pupuk anorganik. Penggunaan POC dari limbah kelapa sawit pada dosis 2,25 cc per bibit per sekali aplikasi nyata lebih baik pertumbuhannya dibanding dengan penggunaan pupuk anorganik. Demikian pula pemberian pupuk hayati pada dosis 0,3% nya menghasilkan pertumbuhan bibit yang lebih baik dibandingkan dengan pemberian pupuk anorganik, akan tetapi bila kedua perlakuan tersebut dikombinasikan justeru tidak lebih baik dibandingkan dengan pemberian pupuk anorganik.

Abstract

Aims and Methods: Oil palm is a strategic commodity that contributes significantly to Indonesia's economy. The losses of oil palm loose fruits during the harvesting and transportation processes of fresh fruit bunches (FFB) pose a serious challenge for oil palm plantation industry, with potential losses reaching 3–7% of total production. This study aims to analyze the distribution pattern of the losses of loose fruits at three observation points (weed circle, carrying market, and harvest collection point (HCP)) at Agritasari Prima Ltd., calculate the economic loss due to these losses, and identify the causative factors. This study employs a qualitative descriptive survey method with sampling at three plantation divisions on flat terrain, covering 1,260 weed circles, 21 carrying markets, and 144 HCPs.Results: The highest loss distribution occurred at carrying market (47.66 fruits/carrying market), followed with weed circle (10.15 fruits/circle) and HCP (8.14 fruits/site). The total economic loss reached IDR 463,143.83, with the largest contribution coming from the losses at weed circle of 85.44% (IDR 395,808), followed by HCP of 7.86% (IDR 36,307), and carrying market of 6.70% (IDR 31,028.83). The annual economic loss due to the losses of loose fruits on flat terrain at Agritasari Prima Ltd. is estimated at IDR 2,178,282,597.31 (around IDR 2.18 billion per year). Major causative factors comprise poorly maintained weed circles, overloaded wheelbarrows, poor route infrastructure at carrying markets, and suboptimal handling at HCPs.Conclusion: Implementation of regular maintenance programs, standardization of vehicles’ capacity, infrastructure improvements, and digital monitoring systems are recommended to reduce the level of losses of loose fruits and improve oil palm plantation operational efficiency.
