Abstract

Among various edaphoclimatic factors influencing coffee bean quality, altitude is one of the primary factors that should be taken into account. This study aims to explore the relationship between altitude, morphological traits, and biochemical composition of robusta coffee in Temanggung Regency, the largest coffee-producing area in Central Java Province, Indonesia. Research sites were purposively selected and categorized into two altitude groups: GS, PS, and GN, located at circa 600 m a.s.l., and GT, WO, and TG, located at circa 900 m a.s.l. A total of 15 morphological traits were observed, consisting of eight vegetative and seven generative traits. Caffeine content was measured following the AOAC procedure using UV-Vis spectrophotometry, while brew acidity was evaluated using a pH meter. Several morphological traits of Temanggung robusta coffee demonstrated significant relationships with altitude. Canopy and stem diameter showed negative correlations with altitude, with correlation coefficients of -0.366 and  -0.408, respectively. Conversely, fruit width               (r = 0.041), bean length (r = 0.049), and bean thickness (r = 0.047) exhibited positive correlations. Regarding biochemical composition, caffeine content stood out by displaying a strong positive correlation with altitude (r = 0.816). Additionally, several morphological traits, including the number of primary branches, the number of productive branches, the number of fruits per bunch, and traits related to fruits and beans, appear to be advantageous for selection and breeding programs. Understanding these relationships provides valuable insights for developing superior Temanggung robusta coffee plants adapted to specific altitudinal conditions.

Abstract

Indole acetic acid (IAA) is an auxin hormone that can regulate plant growth and development. Bacteria produce IAA through L-tryptophan metabolism. The purpose of this study was to determine the ability of endophytic bacteria isolated from Daun Dewa plants to produce IAA to increase the germination and growth of tomato seedlings. Isolation of endophytic bacteria was carried out by sterilizing plant surfaces. The production of IAA is done by adding L-tryptophan precursors. The results showed that there were six endophytic bacteria, and three isolates of them have the potential to produce IAA, namely: AD1.1, UD1.1, and UD2.1. The highest IAA concentration was produced by isolate AD1.1. Growth in sprouts is significantly influenced by the concentration of IAA; the higher the concentration of IAA, the longer the shoots and the roots. Based on the 16S rRNA gene sequence, these isolates belong to the genus Klebsiella.

Abstract

Spirulina is a microalga with spiral or linear trichome shapes that has potential in industrial and food sectors due to its rich nutritional content. Spirulina can live in various aquatic habitats with different environmental conditions. Differences in cultivation environments can affect the morphological characteristics of Arthrospira due to phenotypic plasticity, making morphology-based identification prone to errors. Therefore, molecular identification using the 16S rRNA gene for phylogenetic analysis is necessary. This study aims to identify and analyze the genetic relationships of Spirulina from freshwater and brackish water based on 16S rRNA gene sequences. Freshwater Spirulina samples were taken from Bogor (BGR) and Yogyakarta (MRP), while brackish water Spirulina was taken from Jepara (JPR). DNA extraction was performed using the Zymo Research Quick-DNA Fungal/Bacterial Miniprep Kit, amplification of the 16S rRNA gene was conducted through PCR, followed by DNA sequencing. Phylogenetic analysis was carried out using MEGA11 to construct the phylogenetic tree. The morphology of strains BGR and MRP showed straight and thin filaments, whereas JPR had spiral and relatively long filaments. Sequencing analysis results showed that strains JPR and MRP had the closest homology similarity to Arthrospira sp. IAQUASC-C0001 with percentages of 99.34% and 99.12%, respectively. Meanwhile, Spirulina from BGR had the closest homology similarity to Arthrospira fusiformis strain AICB 668 with a percentage of 99.78%. Phylogenetic analysis indicated that strains BGR, JPR, and MRP are more closely related to Arthrospira than to Limnospira.

Abstract

Alpukat (Persea americana) merupakan buah yang sudah sangat dikenal dan digemari oleh masyarakat. Alpukat diketahui memiliki khasiat sebagai antioksidan, antidiabetik dan efek hipolipidemik. Nutrisi yang terkandung dalam buah alpukat mampu membantu memenuhi kebutuhan nutrisi harian tubuh. Namun, cara budidaya tanaman Alpukat  sangat berpengaruh pada khasiat atau kualitas dan kuantitas dari produk yang dihasilkan. Sehingga diperlukan pemahaman tentang cara budidaya tanaman Alpukat kepada masyarakat. Tujuan yang ingin dicapai dalam kegiatan ini adalah agar masyarakat lebih memahami cara budidaya tanaman alpukat sebagai tanaman pekarangan dan mengetahui manfaat buah Alpukat dalam meningkatkan gizi keluarga. Kegiatan pengabdian sudah dilaksanakan dengan metode penyuluhan dengan penyampaian materi tentang budidaya tanaman Alpukat, manfaat Alpukat, serta berbagai olahan Alpukat sedangkan pada akhir sesi dilakukan pemberian bibit Alpukat serta pupuk pada masing-masing peserta. Kegiatan yang sudah terlaksana ini bermanfaat untuk menambah pengetahuan dan keterampilan masyarakat khususnya masyarakat Kelurahan Wonokarto tentang budidaya tanaman Alpukat dan keanekaragaman manfaat Alpukat untuk kesehatan.Kata Kunci: alpukat; budidaya; penyuluhan; pupuk
