Abstract

The conversion of fertile land into industrial areas and construction development has contributed to the decline of rice production in Indonesia. Therefore, it is necessary to expand the rice fields to the sub-optimal land, i.e. lands with high levels of Fe and Al and low soil pH. One of the solutions that can potentially solve the problem is choosing varieties of rice that can adapt to the suboptimal land environment; the rice varieties can be obtained by estimating rice genetic parameters and selecting the optimal planting methods. One method that can potentially improve rice yield is “System of Rice Intensification”, or SRI method. Our study was conducted in the rice fields on suboptimal land at Pasar Ambacang, Kuranji District, Padang, Sumatra, from December 2019 to April 2020. The aims of the experiment are to determine the genetic parameters and responses of the three rice varieties to suboptimal land using the SRI method. A complete randomized design with four replications was used to set up the experiment using three varieties of rice, i.e. “Batang Piaman”, “Bujang Marantau”, and “IPB3S”. Based on the plant growth measurement and analysis of the genetic parameters, we found that the plant growth characters, particularly height and panicles length, had high heritability and genetic progression values.

Abstract

Pada umumnya untuk memperoleh khasiat yang terdapat pada biji alpukat (Persea americana Mill) dilakukan dengan cara mengiris biji alpukat dan merebusnya. Air rebusan yang diperoleh dengan warna kecoklatan kemudian disaring dan air hasil penyaringan tersebut diminum sebagai obat dengan rasa pahit, dan sisa bijinya hanya memiliki daya simpan berkisar dua sampai 3 hari. Untuk mempertahankan nutrisi yang diinginkan, dan untuk menikmati biji alpukat dengan segala khasiatnya dalam bentuk yang berbeda dan tanpa rasa pahit, maka dilakukan pengolahan biji alpukat menjadi Tepung Biji Alpukat (TBA) dengan metode teknologi pengeringan. Metode eksperimen pengeringan dilakukan dengan menggunakan  food dehydrator dengan menggunakan Rancangan Acak Lengkap (RAL) dengan perlakuan suhu pengeringan yaitu : 50oC, 60oC, 70oC dan 80oC dengan 3 kali ulangan.  Variabel yang diamati adalah kadar  kadar proksimat dan tanin.  Analisa data dilakukan dengan mengunakan analisis sidik ragam (ANOVA) dan dilanjutkan dengan uji Beda Nyata Terkecil (BNT).  Tujuan penelitian ini adalah  untuk menentukan suhu pengeringan yang tepat pada proses pembuatan TBA dengan menggunakan food dehydrator terhadap kualitas dari TBA yang dihasilkan.  Hasil pengeringan terbaik diperoleh dengan pengeringan menggunakan food dehydratord pada suhu 80oC dengan  karakteristik ; warna TBA agak kecoklatan, kadar air 5,12+0,41%, tanin 0,1900+0,0002%, kadar, protein 1,97+0,63%, lemak 2,88+0,17%, karbohidrat 87,47+0,46%, dan kadar abu 2,55+ 0,54%.

Abstract

Abstrak PEG sering dipergunakan untuk seleksi toleransi cekaman kekeringan pada fase perkecambahan benih. Selain itu PEG juga dapat berguna untuk osmoticum priming karena bersifat inert secara kimiawi dan tidak menimbulkan efek merusak pada embrio benih. Penelitian ini bertujuan untuk mengetahui konsentrasi kritis pemberian poly ethylene glycol (PEG 6000) yang menyebabkan penurunan perkecambahan benih 3 varietas cabai local Sumatera Barat sehingga dapat dipergunakan untk skrening toleransi kekeringan genotipe cabai pada fase perkecambahan. Penelitian  ini menggunakan Rancangan Acak Lengkap 2 faktor. Faktor pertama adalah 3 varietas cabai yaitu Cabai Lontabar,  Kopay dan Aka. Faktor kedua  terdiri dari 6 perlakuan konsentrasi PEG yaitu 0%, 5%, 10%, 15%,20% dan 25 %. Hasil penelitian menunjukkan konsentrasi PEG 15% menyebabkan penurunan perkecambahan 3 varietas cabai asal Sumatera Barat. Pada konsentrasi 20% benih cabai sudah tidak berkecambah. Oleh karena itu untuk skrining toleransi kekeringan dapat menggunakan konsentrasi PEG 15% sehingga proses seleksi lebih efektif dan efisien. Kata kunci : Cabai, seleksi, PEG, toleran kekeringan

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

The Taruko Saiyo Farmer Group is a community-based farmer initiative that comprises and grows based on harmony, warmth, and shared interests in utilizing agricultural resources to collaborate in improving the productivity of agricultural enterprises, especially in increasing rice production. Given the strong desire of the members of the Taruko Saiyo farmer group to tackle the issues arising from climate conditions and feeling the need to be accompanied due to a lack of science and technology knowledge regarding climate change mitigation and adaptation, it is appropriate as a partner to support the desires of these farmers and to provide guidance until they can master the science and technology and become an independent farmer group. The purpose of this project is: 1) To help farmers understand climate information and forecasts to support agricultural activities, particularly for planting season decisions and the right technical cultivation strategies as an effort to increase product quantity, 2) To enhance science and technology knowledge and management skills of farmers in managing agricultural waste as support for farming activities, as well as to form an awareness of climate conditions. This community service activity is carried out from June to September 2024. Some of the agendas in this climate field school program include socialization, training, application of science and technology, mentoring, and evaluation. Based on the evaluation results, around 90% of the partner members felt an increase of about ≥80% in understanding, management, science and technology implementation, and production quantity. With ongoing support and active participation from various parties, it is hoped that this program can become a model for sustainable agriculture development.
