Abstract

The leaves of R. stylosa are a potential source of bioactive compounds for health and pharmacology. The composition of bioactive compounds in the leaves can be influenced by the ecological conditions and geographical location of this small island. This study aims to evaluate the toxicity and composition of bioactive compounds that are toxic in mangrove leaf extracts of R. stylosa from Maspari Island in coastal South Sumatra. A total of 1 kg of R. stylosa leaf samples were taken from Maspari Island then washed thoroughly to remove dirt, cut into small pieces, and dried in the sun using the indirect sunlight method covered with black cloth. The dried leaf samples were then pulverized into powder, and as much as 100 grams of fine powder was macerated with 96% ethanol solvent in a ratio of 1:10 (b/v). The maceration process was carried out for 1 x 24 hours, then the maceration solution was filtered and evaporated using a rotary evaporator at 60°C to become a concentrated extract. Toxicity tests were carried out using the Brine Shrimp Lethality Test (BSLT) method, while the identification of toxic bioactive compounds was carried out through phytochemical tests, total phenol tests, and GC-MS analysis. The test results showed that the LC50 value of R. stylosa leaf extract was 393 mg/mL (moderately toxic). The total phenol content was 442.82 (gGA/g), and the bioactive compounds identified included alkaloids, flavonoids, saponins, terpenoids, and acids such as Hexadecanoic acid, methyl ester, and trans-13-Octadecenoic acid, methyl ester.

Abstract

K. candel (L.) Druce, including one of the rare mangroves that need unique management. This study aimed to determine the vegetation structure, habitat, and abundance of K. candel. Determination of stations and points of research transects using the line transect method at five observation stations with each observation station consisting of three transect lines. The results showed that 13 species from 8 families were divided into primary, minor, and association mangrove categories. K. candel habitat in Pulau Payung was found at observation station 2 with a salinity of 0 ‰ and a clay substrate type. K. candel was also found at observation station 4 with a 0% salinity and a sandy clay substrate type. The vegetation that dominates on Payung Island is the A.alba BI type. seen from the Importance Value (NP) at the tree level of 77.77%, sapling level of 86.67%, and at the seedling level of 65.52%. The significance value of K. cande at the tree level was 30.59%, the sapling level was 47.33%, and at the seedling, the level was 24.48%. This suggests that the abundance of K. Candel is limited.

Abstract

Salah satu bentuk penyebaran pengetahuan (transfer of knowledge) dalam upaya menggalakkan pertanian yang berwawasan lingkungan dan berkelanjutan adalah melalui kegiatan uji tanah sawah untuk menentukan rekomendasi pemupukan yang berimbang bagi lahan pertanaman padi sawah. Uji tanah sawah dengan menggunakan Perangkat Uji Tanah Sawah (paddy soil test kit) dan analisis sampel tanah telah dilakuan di Desa Wonodadi Utara, Kecamatan Gading Rejo, Kabupaten Pringsewu, Lampung untuk menentukan status kandungan unsur hara N, P, K dan rekomendasi pemupukan N, P, K pada tanah sawah tersebut. Selain melakukan uji dan analisis tanah, penyuluhan penggunaan bahan organik yang berasal dari limbah pertanian lokal, seperti jerami padi, sekam dan kotoran hewan ternak sebagai sumber pupuk organik bagi tanah sawah juga dilakukan agar kebutuhan unsur hara lain selain N, P, K dapat terpenuhi bagi tanaman padi. Hasil analisis tanah menunjukkan bahwa status kandungan hara N pada sampel tanah sawah sangat rendah dan rendah, kandungan hara P sangat rendah dan rendah dan kandungan hara K rendah. Dosis pupuk yang direkomendasikan berdasarkan status hara tanah tersebut adalah 240 kg NPK Phonska/ha + 172 kg Urea/ha + 40 kg KCl/ha atau setara dengan 43,2 kg NPK Phonska + 30,96 kg Urea + 7,2 kg KCl untuk luasan lahan 1800 m2 atau per petak lahan sawah. Petani dapat mengganti pupuk KCl dengan kompos jerami padi karena kandungan K yang tinggi pada jerami padi. Petani sangat dianjurkan mengaplikasikan pupuk organik dalam bentuk kompos jerami padi karena selama ini petani hanya mengaplikasikan pupuk anorganik.

Abstract

The field and laboratory experimental studies were conducted to determine the phosphorus (P) adsorption behavior employing Langmuir Method and yield of sugarcane as affected by compost and inorganic fertilizer applications, and to determine the correlations between the Langmuir parameters and the availability of P in soil or harvested P by the sugarcane. Both field and lab experiments were arranged in a randomized block design, consisting of five treatments (A= 100% NPK, B=100% compost, C=100% NPK + 50% compost, D= 50% NPK + 100%, compost, and E= no fertilizer).  Each treatment was replicated three times. Field and laboratory studies were carried out in the sugarcane field and in the Laboratory of Soil Science, the University of Lampung for Langmuir P studies, respectively. The results showed that the applications of 100% NPK plus 50% organic fertilizer, and 100% NPK resulted in the highest amount of available-P in the soil, the lowest maximum adsorption of P (Xm) and the lowest relative bonding energy of P (km); as well as the highest effect on the increase of sugarcane production. On the other hand, the treatments of no fertilizer and the 100% organic fertilizer resulted in the highest maximum adsorption of P (Xm) and the lowest sugar production. There were very significant negative correlations between the maximum adsorption of P (Xm) and soil P, harvested P by the sugarcane and stem biomass; while similar trend but no significant correlations between the relative bonding energy of P (km) and soil P, harvested P, leaf biomass and stem biomass were detected.

Abstract

The extraction methods using Bray P-1, Mehlich-1, and Olsen solutions are the most frequently used in equilibrium condition to estimate the available P in the soil constituents. However, each method can gives some different values that may not describe the availability of soil P. Therefore, it is necessary to conduct a laboratory experiment to compare the three solutions in equilibrium and kinetics conditions for P release from soil colloids as a basic data for the future related to plant productions. The objective of this study was to compare the amounts of P release in equilibrium and kinetics conditions using Bray P-1, Mehlich-1, and Olsen solutions and the rate constants (k) of P release from soil colloids using the three solutions of five soil constituents or treatments: (1) Soil (100% soil), (2) P-rock (100% phosphate rock), (3) compost (100% chicken manure compost), (4) soil + P-rock (75% soil + 25% phosphate rock), and (5) soil + P-rock + compost (50% soil + 25% phosphate rock + 25% chicken manure compost). Each extraction for each treatment was conducted in triplicate. The results indicate that the amounts of extracted P employing equilibrium condition in all treatments are significantly lower compared to those employing kinetics condition. The results also show that Mehlich-1 solution is the most powerful solution to extract P from soil constituents followed by Bray P-1 solution and Olsen solution, except that in the soil + phosphate rock + compost treatment in which the amount of P extracted using Mehlich-1 solution is the highest then followed by that of P extracted by Olsen solution and Bray P-1 solution both in equilibrium and kinetic conditions. The highest rate constants (k) of the reaction in all treatments were found in the extractions using Mehlich-1 solution for desorbed P followed by that of using Bray P-1 solution and Olsen solution. Keywords: Compost, equilibrium, kinetics, P extraction solutions, phosphate rock, soil

Abstract

Heavy metal pollution, including lead (Pb), zinc (Zn), and copper (Cu) in swamp environments, is increasing and poses a significant threat to ecosystem integrity and human health. This study aims to evaluate the phytoremediation potential of Eleocharis dulcis in accumulating heavy metals in root, stem, and leaf tissues. The experimental method involved growing Eleocharis dulcis for 20 days in media artificially contaminated with Pb, Zn, and Cu metals at concentrations of 5, 10, and 15 ppm. Observations were made on metal accumulation in plant tissues on days 5, 10, 15, and 20. The results showed that concentration and duration of exposure significantly influenced the pattern of metal accumulation. The highest accumulations were recorded in leaf tissue, specifically Pb at 87.527 mg/kg, Zn at 32.93 mg/kg, and Cu at 43.522 mg/kg. These findings indicate that Eleocharis dulcis has selective metal uptake and translocation mechanisms and high tolerance to heavy metal stress, and has the potential to be an effective phytoremediation agent for the rehabilitation of heavy metal-contaminated wetlands and support sustainable environmental management.

Abstract

Penelitian ini bertujuan untuk mengetahui densitas serangga predator dan polinator pada komposisi dan struktur vegetasi mangrove yang berbeda di kawasan ekosistem mangrove Desa Marga Sungsang dan Desa Sungsang IV, Kabupaten Banyuasin, Sumatera Selatan. Metode yang digunakan adalah deskriptif kuantitatif dengan teknik survei in-situ melalui observasi langsung terhadap vegetasi mangrove serta pengambilan sampel serangga menggunakan tiga teknik yaitu hand collecting, chemical knockdown, dan yellow trap. Titik sampling ditentukan secara purposive sampling dengan plot berukuran 10 x 10 m² pada transek 100 x 50 m² di setiap lokasi. Hasil penelitian menunjukkan bahwa serangga predator lebih dominan dan bervariasi dibandingkan serangga polinator. Terdapat hubungan timbal balik antara vegetasi mangrove dan serangga, di mana mangrove menyediakan habitat dan sumber makanan, sementara serangga membantu proses penyerbukan dan predasi. Struktur dan komposisi vegetasi berpengaruh signifikan terhadap kerapatan serangga, di mana vegetasi yang lebih kompleks mendukung keanekaragaman dan kepadatan serangga yang lebih tinggi.
