Abstract

Sugar palm seed germination does indicate by the appearance of a tissue that extends like a sponge called apokol which is penetrating the hard seed coat and can occur in several positions in germinated sugar palm seeds. No research reports discuss the relationship between this apokol position and the phenology of sugar palm seed germination. This research aims to study the relationship between apokol position and the growth of sugar palm seedlings and their genetic diversity. The research applies Experiment in Completely Random Design with four treatments, each repeated five times. The four treatments are the apokol position, namely A: Apokol in right-center, B: Apokol in left-center, C: Apokol in left-bottom, and D: Apokol in right-bottom. The results showed that the fastest time for the coleoptile emergence was 40 days after transplanting in the right-center apokol position. Morphologically, there was no significant difference in the sugar palm seedling growth with each apokol position. On the other hand, we found that there were genetic diversities among them revealed by Simple Sequence Repeat (SSR) markers. The palm seeds with the right-center apokol position included the first cluster, and the second cluster consisted of left-center apokol, right- bottom apokol, and left-bottom apokol.

Abstract

Rainfall variability, in terms of amount, distribution, and timing, can increase the risk of crop failure and reduce crop yields. This study aims to analyze CHIRPS (Climate Hazards Group InfraRed Precipitation with Stations) rainfall dynamics across several coastal areas of West Sumatra and to evaluate agroclimatic zones to assess the suitability of climate-adaptive cropping patterns. Monthly rainfall data for the period 1995-2024 were analyzed using the IDW interpolation method to produce rainfall distribution maps. This study also classified agroclimatic zones using Oldeman's classification to assess the suitability of cropping patterns. The analysis showed significant annual rainfall fluctuations, with high rainfall dominating the 1995-2014 period and a decline in the 2015-2024 period. Changes in monthly rainfall patterns, particularly the increase in rainfall from March to May during the 2015-2024 period, may affect planting times and irrigation management. The three regions studied (Padang Pariaman, Pariaman, and Padang) are in climate zone A1, with more than 9 consecutive wet months, allowing year-round rice cultivation. However, rainfall fluctuations require adjustments in planting timing and the selection of secondary crops that are more drought-resistant. The results of this study provide a stronger basis for agricultural planning that is more adaptive to climate change, with recommendations for adjustments to the planting calendar and irrigation management to ensure the sustainability of efficient and sustainable agricultural production.

Abstract

Pembukaan lahan merupakan kegiatan membuka atau membersihkan lahan yang awalnya hutan atau ditanami pepohonan menjadi lahan yang akan digunakan untuk berbagai kegiatan. Pembukaan lahan dilakukan oleh petani untuk membuka lahan yang akan dipakai untuk lahan pertanian. Pembukaan lahan penting bagi sebagian orang apalagi yang bekerja sebagai pekebun ataupun petani, banyaknya masyarakat yang bekerja sebagai pekebun menimbulkan tumbuh pesatnya pemanfaatan lahan. Penggunaan lahan tersebut jarang sekali memperhatikan kondisi lahan untuk diolah, banyak juga kondisi lahan yang mempunyai keterbatasan fisik maupun kimia namun masih saja diolah dan ini mengakibatkan rusaknya lahan, salah satu contohnya adalah kebakaran lahan. Masyarakat di Nagari Sungai Dareh dalam pengelolaan SDA (Sumber Daya Alam) masih banyak diakukan dengan menggunakan media api, salah satu kegiatan masyarakat yang berhubungan dengan penggunaan media api antara lain: pembukaan lahan untuk persiapan sawah/kebun/ternak, pencarian lokasi ikan di rawa-rawa dengan cara membakar semak-semak yang menutupi permukaan air, pemberantasan hama tikus/babi, dan sebagainya. Penyiapan lahan tanpa bakar adalah teknik pembuatan rintisan dan pembagian petak tanaman dengan menggunakan alat. Keuntungan dari teknik mengolah lahan tanpa bakar yaitu dalam aplikasinya tidak terlalu tergantung pada kondisi cuaca, kecuali kondisi yang terlalu basah karena dapat menghambat mobilitas alat berat. Selain itu, kelebihan utama teknik ini adalah jauh lebih ramah lingkungan dibandingkan dengan teknik pembakaran. Selain manfaat lingkungan dan agronomis, pembukaan lahan tanpa bakar juga memberikan nilai tambah ekonomis.
