Abstract

Tanaman pala (Myristica fragrans H) merupakan tanaman asli Indonesia yang memiliki peranan penting dalam perekonomian daerah dan nasional di Indonesia. Pala sebagai tanaman rempahrempah dan sumber minyak atsiri, merupakan tanaman penting, karena dapat menghasilkan minyak eteris dan lemak khusus yang berasal dari biji dan fuli. Peran komoditas pala dalam peningkatan perekonomian nasional kian terasa oleh masyarakat. Terbukti dengan tingginya permintaan pala di pasar dunia yang mendorong minat masyarakat untuk terus membudidayakan pala diberbagai daerah. Oleh karena itu dengan potensi itu semua yang terdapat di Kabupaten Pesawaran maka peran baik masyarakat, pemerintah dan berbagai stakeholder sangat krusial dalam upayanya mengembangkan tanaman pala. Adapun kegiatan yang telah dilaksanakan di Desa Wiyono yaitu pendampingan tentang pemanfaatan teknologi kombinasi pupuk kimia dengan memanfaatkan pupuk hayati, menerapkan kegiatan aplikasi pupuk hayati terutama pada saat pembibitan dan awal penanaman pala, dan membentuk unit percontohan penerapan teknologi aplikasi pupuk hayati. Berdasarkan hasil dan pembahasan yang telah didapat yaitu sebagai berikut Meningkatkan pengetahuan, pemahaman dan keterampilan anggota kelompok tani dalam memanfaatkan teknologi kombinasi pupuk kimia dengan memanfaatkan pupuk hayati untuk meningkatkan produktivitas tanaman pala. Kata kunci: pupuk hayati, pala

Abstract

The provinces of West Lampung and Tangamus are areas of robusta coffee development and as one of the leading Indonesian coffee producers in Indonesia. Lampung Province has a geographical area and climate suitable for the growth and development of robusta coffee. Robusta coffee, although derived from vegetative plants, often shows varied phenotypic responses based on environmental differences. A plant must be affected by internal factors such as genetics or from outside such as the environment, the process of growth and development. Coffee plants tend to want to grow in the highlands so that in the lowlands they don't. The research is aimed at identifying microclimate conditions in lowland coffee plantations, as a reference in environmental modification in order to optimize growth and produce optimal productivity. Early research was carried out in August – November 2021 in the experimental garden of the Lampung State Polytechnic. The method in this experiment uses a survey method. The results obtained are microclimate conditions that vary between plots and there is a unidirectional correlation between climate elements and in line with production results based on linear regression tests carried out, namely with a value > 0.5 which indicates that each component of the climate element is very strong in influencing one with the other. others as well as production. Provinsi Lampung Barat dan Tangamus merupakan daerah pengembangan kopi robusta dan sebagai salah satu produsen kopi Indonesia ternama di Indonesia. Provinsi Lampung memiliki wilayah geografis dan iklim yang sesuai untuk pertumbuhan dan perkembangan kopi robusta. Kopi robusta, meskipun berasal dari tanaman vegetatif, sering menunjukkan respon fenotipik variatif berdasarkan perbedaan lingkungannya. Suatu tanaman pasti terpengaruh faktor dari dalam seperti genetis atau dari luar seperti lingkungan, proses pertumbuhan dan perkembangannya. Tanaman kopi cenderung menghendaki tumbuh pada dataran tinggi sehingga pada dataran rendah tidak. Adapun penelitian ditujukan mengidentifikasi kondisi iklim mikro di perkebunan kopi dataran rendah, sebagai acuan dalam modifikasi lingkungan guna mengoptimalkan pertumbuhan serta menghasilkan produktivitas yang optimal. Penelitian dini dilaksanakan pada Agustus – November 2021 dikebun pecobaan Politeknik Negeri Lampung. Metode dalam percobaan ini menggunakan metode survei.  Hasil yang diperoleh terdapat kondisi iklim mikro yang bervariatif antar plot serta terdapat korelasi yang searah antar unsur iklim serta selaras dengan hasil produksi berdasarkan uji regresi linier yang dilakukan, yaitu dengan nilai > 0,5 yang mengindikasikan setiap komponen unsur iklim sangat kuat dalam mempengaruhi satu dengan yang lainya begitupun juga dengan produksi.

Abstract

This study investigated the growth responses of four rubber scion clones (GT 1, IRR 112, PB 260, and RRIC 100) to different fertiliser types and concentrations at Politeknik Negeri Lampung from August to December 2024. The experiment employed a factorial randomised complete block design with two factors: clone type (four levels) and fertiliser treatment (5% NPK, 10% NPK, 5% KNO?, and 10% KNO?). Growth parameters, including leaf number, chlorophyll content, branch number, and leaf whorl number, were measured 2 and 4 months after treatment. The results showed highly significant effects (P < 0.05) of clone type, fertiliser treatment, and their interaction on all measured parameters. Clone GT 1 consistently exhibited superior performance across all variables, with the combination of GT 1 and 10% NPK producing the highest values: 94.00 leaves, 66.25 SPAD units, 7.75 branches, and 62.00 whorls four months after treatment. The 10% NPK treatment significantly outperformed KNO? formulations across all clones, demonstrating the importance of balanced macronutrient nutrition, including phosphorus. The study concluded that GT 1 clone fertilised with 10% NPK solution represents the optimal combination for maximising scion production efficiency in rubber nursery systems, providing valuable guidance for clone-specific nutritional management strategies.

Abstract

Pepper cultivation in Bangka Island primarily takes place on sandy land. Legume cover crops, such as Centrosema pubescens, which has been widely used as a ground cover, are anticipated to improve land quality by maintaining soil temperature and humidity, increasing soil organic carbon content, increasing soil porosity, and improving soil fertility. This research aims to analyze the agroecosystem of pepper plants, by comparing the use of the cover plant C. pubescens as a soil treatment and the absence of using these cover plants as a control. The research was conducted in farmers’ pepper gardens in Perlang Village, Central Bangka Regency, Bangka Belitung Province. The research employed a randomized block design, with C. pubescens and natural vegetation as treatments, each replicated 3 times. The variables measured were soil temperature and humidity; abundance of microorganisms; weed density, frequency, and dominance; chlorophyll a, chlorophyll b, and anthocyanin content of pepper leaves; photosynthesis rate; transpiration rate; stomatal conductance; soil chemical and physical properties. The results showed that C. pubescens as ground cover could reduce the dominance of the Bidens pilosa weed (relative dominance of 36.16%) but led to an increase in the dominance of Chromolaena odorata (relative dominance of 38.7%). C. pubescens ground cover could also maintain stable soil temperature and moisture, and increase P, K, Ca, and Mg soil content by 100%, 100%, 43.6%, and 48.3%, respectively. Furthermore, pepper plants grown with C. pubescens exhibited 25%, 23.7%, and 16% higher chlorophyll a, total chlorophyll, and carotenoid content, respectively, compared to those grown without the cover crop.
