Abstract

Pertumbuhan bibit kelapa sawit sangat dipengaruhi oleh kualitas media tanam, termasuk kandungan bahan organik yang digunakan. Lamanya dekomposisi bahan organik turut menentukan ketersediaan unsur hara bagi tanaman sejak awal pertumbuhan. Penelitian ini bertujuan untuk mengkaji pengaruh jenis bahan organik dan lama dekomposisi terhadap pertumbuhan bibit kelapa sawit pada budidaya pra-pembibitan. Penelitian ini menggunakan percobaan faktorial dengan rencana acak lengkap (RAL) yang terdiri dari dua faktor dan tiga kali ulangan. Faktor pertama adalah berbagai jenis bahan organik (pupuk kandang, legum, eceng gondok). Faktor kedua adalah lama dekomposisi bahan organik yang diamati pada minggu pertama, kedua, dan ketiga. Data hasil penelitian dianalisis menggunakan analisis ragam (ANOVA) dengan taraf nyata 5%. Apabila terdapat perbedaan nyata dilanjutkan dengan Uji Jarak Berganda Duncan (UJT) pada taraf nyata 5%. Hasil penelitian ini secara umum menunjukkan bahwa bahan organik legum memberikan hasil yang lebih stabil dan cenderung lebih baik dibandingkan pupuk kandang dan eceng gondok untuk semua parameter pertumbuhan bibit kelapa sawit pada tahap pra-pembibitan. Secara statistik, hasilnya tidak menunjukkan perbedaan yang signifikan antar perlakuan. Namun secara numerik, bahan organik legum lebih konsisten dalam mendukung pertumbuhan vegetatif bibit kelapa sawit. Penelitian ini tidak hanya memberikan kontribusi pada aspek teknis budidaya tetapi juga meningkatkan pemahaman tentang manfaat biomassa legum sebagai sumber nutrisi yang efektif dan efisien dalam mendukung pertumbuhan awal bibit kelapa sawit.

Abstract

This community service program was implemented in Koto Malintang, West Sumatra, to empower farmer groups through the development of an Aren sugar (Arenga pinnata) production center. The activities consisted of pre-surveys, focus group discussions (FGDs), socialization workshops, participatory planning, and initial demonstrations of intercropping practices. A key component of the program was the financial feasibility analysis, designed to provide farmers and stakeholders with evidence-based tools for decision-making. The analysis was conducted using production costs and revenues from the research location, with a 15-year horizon and a 10% discount rate. Two cultivation scenarios were evaluated: (1) Aren intercropped with seasonal crops and (2) Aren intercropped with robusta coffee. Each scenario considered two product alternatives: molded sugar (gula cetak) and palm sugar crystals (gula semut). The results revealed that molded sugar offered only marginal feasibility, with Net Present Values (NPV) of Rp 28–35 million/ha, Internal Rates of Return (IRR) of 12–15%, Benefit-Cost (B/C) ratios around 1.1, and payback periods of 7–8 years. In contrast, palm sugar crystals showed strong financial viability, with NPVs of Rp 298–330 million/ha, IRRs of 38–45%, B/C ratios of 2.4–2.6, and payback periods of only 4–5 years. Sensitivity analysis confirmed robustness across discount rates of 8–12% and price variations between Rp 40,000–60,000/kg. These findings suggest that palm sugar crystals should be prioritized as the flagship product for Koto Malintang’s Aren sugar industry, supported by institutional strengthening, diversification, and modern marketing to ensure sustainability.

Abstract

Kegiatan pertambangan khususnya batu bara berpotensi memberikan dampak negatif bagi lingkungan karena menyebabkan kerusakan lahan. Adapun guna merehabilitasi lahan tersebut diperlukan suatu tindakan revegetasi, antara lain menggunakan bantuan Fungi Mikoriza Arbuskular (FMA). Penelitian ini bertujuan untuk mengetahui persentase kolonisasi spora FMA yang mengindikasikan tingkat kecocokan antara FMA dengan vegetasi eksisting di lahan pasca tambang batu bara pada beberapa kelerengan yang berbeda, sehingga diharapkan dapat diperoleh suatu informasi awal dalam menentukan jenis tanaman yang cocok untuk dikombinasikan dengan spora FMA yang mendukung langkah revegetasi tersebut. Tahapan kajian yang dilakukan ialah mengambil sampel tanah lahan bekas tambang batu bara, identifikasi vegetasi, ekstraksi spora, dan identifikasi spora FMA yang ditemukan. Pengambilan sampel tanah untuk analisis sifat kimia tanah serta pengamatan spora mikoriza pada lahan bekas tambang batu bara dilakukan berdasarkan random sampling pada kedalaman 0-20 cm dengan 5 tipe kelerengan, yaitu datar, landai, agak curam, curam, dan sangat curam. Hasil penelitian menunjukkan bahwa kolonisasi mikoriza di dalam tanah lahan pasca tambang batu bara memiliki nilai persentase yang berbeda pada masing-masing tipe kelerengan, yaitu mencapai 30% (datar), 21,58% (landai), 13,16% (agak curam), 23,34% (curam), dan 6,19% (sangat curam). Semakin curam lereng, kolonisasi akan semakin menurun. Berdasarkan frekuensinya, Glomus sp. dapat ditemukan pada setiap tipe kelerengan, sehingga mengindikasikan bahwa jenis FMA tersebut mampu bersimbiosis dengan baik dengan tumbuhan yang ditemukan antara lain seperti Centrosema pubescens, Fimbristylis littoralis, Vigna luteola, Alysicarpus vaginalis, dan Mimosa sp. Persentase kolonisasi akar berkorelasi negatif dengan kadar P dan berkorelasi positif dengan kadar Ca dalam tanah. Persentase kolonisasi spora FMA tertinggi terjadi pada lereng datar dengan vegetasi Centrosema pubescens.

Abstract

The clove stem borer (Nothopeus hemipterus) is a major pest causing significant economic losses in clove cultivation. In Samigaluh, most farmers rely on chemical pesticides for control. However, essential oils and entomopathogenic fungi offer safer and more sustainable alternatives. This study aimed to evaluate their effectiveness and determine the most suitable control method. The research was conducted in Kayugedhe Hamlet, Samigaluh, Kulon Progo, Yogyakarta, from April to September 2022. A randomized completely block design was used with different pest control treatments, including chemical pesticides (fipronil, acephate, and profenofos), botanical pesticides (10% neem oil and 10% citronella oil), biological pesticides (Beauveria bassiana at 1 × 10⁸ CFU/mL), and a control. The pesticides were applied using a hydraulic pump and a wax-sealing method on larval entry holes. Larval mortality was recorded weekly for four weeks. The results showed that the application of entomopathogenic fungi (Beauveria bassiana) and citronella oil led to larval mortality rates of 78% and 75%, respectively, which were comparable to the effectiveness of fipronil (80%) and acephate (81%). In contrast, N. hemipterus larvae exhibited lower susceptibility to profenofos, with a mortality rate of only 47%, suggesting potential resistance. These findings indicate that B. bassiana and citronella oil extract could serve as effective and environmentally friendly alternatives for controlling the clove stem borer.

Abstract

Nagari Sungai Dareh is a part of the Punjung Island District, West Sumatra which has a relatively flat topography and tropical climate. Most of the population works as farmers, so there are many rice planting areas. Problems faced by local farmers are blast and bacterial leaf blight disease attacks, while no appropriate control methods have been found. Therefore, this service was carried out which aims to increase farmers' knowledge about the symptoms and control of these two types of diseases. The equipment used in this activity includes stationery, projectors, presentation materials, and speakers. This service activity was carried out in 3 stages which included 1) Focus Group Discussion, 2) location survey and direct observation in rice cultivation fields, and 3) education and extension on the symptoms and control of blast and bacterial leaf blight diseases. During the presentation, farmers were enthusiastic in listening. Discussions took place well between the presenters and farmers. Blast disease is caused by the fungus Pyricularia oryzae, while bacterial leaf blight is caused by the bacterium Xanthomonas oryzae. Blast disease gives symptoms in the form of grayish-brown rhombic spots, while bacterial leaf blight symptoms are yellowing, pale, dry leaves starting from the tips, edges to spread to all parts of the leaf. Both diseases can be well controlled through the use of resistant varieties and improved cultivation techniques. The application of appropriate doses of N fertilizer can suppress blast and bacterial leaf blight attacks, because the higher the N applied causes the plant tissue to be softer, making it easily infected by fungi and bacteria. This activity succeeded in increasing farmers' knowledge about the symptoms of blast and crackle diseases and the best methods to suppress them.
