Abstract

Urban home gardens play an important role in supporting biodiversity conservation within urban landscapes. However, information on the floristic composition and vegetation structure of urban home gardens in Indonesian cities remains limited. This study assessed plant diversity, vegetation structure, and alpha diversity of urban home gardens in Makassar, South Sulawesi, Indonesia. Field surveys were conducted in 24 home gardens selected using purposive sampling. All plant species were identified and classified into lower, middle, and upper vegetation strata. Species richness, family composition, and diversity indices were subsequently analyzed. A total of 190 plant species belonging to 65 families and 2,527 individuals were recorded. Araceae and Asparagaceae were the most species-rich families. The middle stratum contained the highest proportion of species (42.1%), followed by the upper (29.5%) and lower strata (28.4%). Mean species richness was 12.8 ± 3.6 species per garden, while Shannon–Wiener diversity, Simpson diversity, and evenness indices were 2.0 ± 0.49, 0.80 ± 0.13, and 0.60 ± 0.18, respectively. These findings demonstrate that urban home gardens in Makassar maintain considerable plant diversity and a multi-layered vegetation structure despite ongoing urbanization. Urban home gardens therefore represent important components of urban green infrastructure and biodiversity conservation.

Abstract

Residential home gardens are important components of urban green spaces that contribute to biodiversity conservation, food security, and public health. This study examined the effects of an Urban Home Gardening Program on home garden structure and plant diversity in Malang City, Indonesia. A total of 95 households were surveyed, comprising participants in the government program (JGP) and non-participants (NJGP). Data on home garden typology, plant composition, abundance, and plant diversity were analyzed using descriptive statistics, chi-square tests, and independent-samples t-tests. Three home garden types were identified: ground, mixed, and vertical/rooftop. Mixed gardens predominated among JGP households (48%), whereas ground gardens were more common in NJGP households (56%). Ornamental plants were the dominant plant group, followed by vegetables, fruits, medicinal plants, tubers, and staple food crops. JGP households maintained significantly higher plant diversity (13 vs. 8.4 varieties; p < 0.05) and a greater proportion of medicinal plants (59% vs. 32%; p = 0.013) than NJGP households. These findings indicate that the Urban Home Gardening Program primarily enhances plant diversity and promotes multifunctional home gardens rather than simply increasing plant abundance. The program therefore has considerable potential to strengthen urban biodiversity conservation, household food security, and the sustainable use of medicinal plants.

Abstract

Limbah padat kelapa sawit berpotensi menjadi prekursor karbon aktif yang murah untuk pengolahan air. Penelitian ini bertujuan memetakan perkembangan publikasi, kontributor utama, artikel berpengaruh, dan struktur tema riset material karbon dari limbah padat kelapa sawit untuk pengolahan air. Data diperoleh dari Scopus untuk periode 2017-2026. Sebanyak 591 dokumen hasil pencarian disaring menjadi 87 artikel melalui kriteria formal serta penyaringan judul dan abstrak. Analisis kinerja menggunakan Scopus Analyze Search Results, sedangkan pemetaan kata kunci menggunakan VOSviewer 1.6.21. Sebanyak 56,3% artikel terbit pada 2022-2026. Malaysia terlibat dalam 52,9% artikel dan Indonesia dalam 27,6%. Delapan dari sepuluh artikel yang paling banyak dikutip menguji zat warna atau logam berat. Peta kata kunci membentuk enam klaster yang berpusat pada adsorpsi, karbon aktif, dan cangkang inti sawit. Cangkang inti sawit dibahas pada 64,4% artikel, sedangkan serat mesokarp hanya 5,7%. Sistem kolom, regenerasi, dan efektivitas biaya berada di pinggir peta dengan kemunculan rendah. Kebaruan penelitian terletak pada pengukuran kuantitatif jarak antara uji laboratorium dan penerapan operasional. Penelitian lanjutan perlu menguji air limbah nyata, sistem kolom, regenerasi, evaluasi biaya, dan keamanan residu aktivator.
