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

Sugar-palm is an industrial crop whose almost all parts can be utilized, potentially improving the wealth of the society and the national economy. Despite its great potential, the development of sugar palm in Indonesia is still low, so it is necessary to do breeding through exploration and morphological characterization of germ plasm. In Talamau, West Pasaman, sugar palm still comes from wild forest, there is potential for superior individuals that have not been optimally utilized. The purpose of this study was to obtain information on the character and germ plasm of sugar palm in Talamau, West Pasaman. The research was conducted in May-July 2024 in Talamau, West Pasaman. The method used was survey with descriptive data presentation. The sampling technique used was purposive sampling. The plants used as samples are plants that meet the specified criteria, namely having entered the generative phase and tapped by farmers. The results showed that there were 14 accessions of sugar palm trees in Talamau. From the accessions, the characters that have wide diversity are plant height, stem circumference, number of leaflets, leaflet length, male bunch distance, fruit diameter, fruit weight, and sap yield. While narrow diversity in the character of midrib length, rachis length, stalk length, number of female flower bunches, seed diameter, number of seeds, and soluble sugar content. Then based on cluster analysis, the accessions of sugar palm in Talamau are divided into two clusters separated by the surface character of palm fiber with a level of 0-35% dissimilarity.

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

Maize is a light-dependent crop, but new varieties have been developed that can tolerate shade. This allows farmers to grow maize as an intercrop between coconut trees, making more efficient use of their land. Farmers can also intercrop with legume plants, which provide additional nitrogen through Rhizobium bacteria, leading to increased maize productivity. The aim of this study was to obtain the best intercropping pattern for maize and soybeans under coconut trees that results high yields in maize. The study was conducted in Padang Pariaman Regency of West Sumatra, at an altitude of approximately 150 meters, from February to July 2022. The experimental design was a Split Plot Design with Randomized Block Design, consisting of three main plot levels (planting time) and four subplot levels (planting model). The results of the study indicate that intercropping maize and soybeans under coconut trees has no effect on the weight of maize cobs, but there is a positive correlation between ear weight, cob length, cob diameter, number of rows per cob, and the weight of 1000 maize seeds.

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

Objectives of experiments were to evaluate (1) in vitro inhibitory effects of plant extracts on Clavibacter michiganensis subsp. michiganensis (Cmm), (2) inhibitory effects of plant extracts on Cmm infected tomato seeds, and (3) effectiveness of seed treatment plus plant extracts to eliminate Cmm. After evaluating 20 plant extracts, curcuma rhizome and betel vine leaf extract, cinnamon and clove oil were selected for further test. Tomato seeds were artificially inoculated with Cmm to obtain high level of infection. Part of the seeds were dipped in either suspension of selected extracts for 20 minutes and the others were matriconditioned using a mixture of burned rice hull (at 22 °C and RH 60-70%) plus either of plant extracts oils, respectively. Elimination of Cmm level from infected seeds was observed at 10 days after treatments. Results of the experiment indicated curcuma extract, betel vine extract, cinnamon oil or clove oil showed in vitro inhibitory effects on Cmm. Moreover, dipping infected seeds in either 5% of curcuma, betel vine extract, or 0.5% of clove oil or matriconditioning plus these extracts oils were effective to eliminate Cmm from infected seeds. These treatments may potentially be used and developed commercially for eliminating seedborne Cmm on infected tomato seeds.   Keywords: Bacterial cancer, seedborne-pathogen, seed-treatments

Abstract

The germination process is the key to plant phenology, which significantly influences the success of early plant growth. Some seeds have a dormancy, so the germination process is hampered or does not occur. However, dormancy-breaking treatments in plants have been widely reported, such as breaking the dormancy of sugar palm seeds through physical scarification. This research aims to determine the best scarification position to break the dormancy of sugar palm seeds. This research was carried out at the Seed Technology Laboratory, Faculty of Agriculture, Universitas Andalas from July to October 2023. The design was completely randomized with scarification in two position variations, the operculum (A1) and dorsal (A2) points, repeated thrice. The results showed that the position of seed scarification affected the emergence time of cotyledon petioles and coleoptiles, germination capacity, and seed moisture content. Scarification at the operculum point requires a dormancy break of 16 DAP (Days After Planting) compared to 29 DAP for the dorsal. Seed viability was good in seeds sacrificed at the operculum point, with a germination percentage of 81.94%. Keywords: dorsal, operculum, cotyledon petiole
