PERTUMBUHAN TANAMAN DAN STRUKTUR ANATOMI DAUN KEDELAI, KACANG PANJANG, DAN KACANG TANAH PADA KETINGGIAN TEMPAT YANG BERBEDA

2025-12-31T12:54:59+00:00

Soybeans, yardlong beans and peanuts are cultivated crops widely grown in the tropics at different altitudes. Differences in environmental factors between lowlands and highlands will affect plant growth and leaf anatomical structure. The study aimed to determine the growth and anatomical structure of the leaves of soybean, yardlong bean and peanut plants at different altitudes. The test plants were grown at two different altitudes. At an altitude of Â± 20 masl, the test plants were placed in the greenhouse of the Biology Department of the Faculty of Mathematics and Natural Sciences, Tadulako University and at an altitude of Â± 630 masl, the test plants were placed in Bahagia Village, Palolo District, Sigi Regency. The results showed that yardlong bean and peanut plants grown at an altitude of Â± 630 masl had a lower stomatal density than those grown at Â± 20 masl so the plant dry weight produced was also lower. Soybean plants have a larger stem diameter and plant dry weight at an altitude of Â± 630 masl, these are due to the higher stomatal density and leaf thickness compared to those grown at an altitude of Â± 20 masl.

This research aims to determine the growth and production as well as the optimal dosage for white oyster mushroom fruiting bodies on a basic substrate of oil palm empty fruit bunch and sawdust. The study was designed using a completely randomized design (CRD) with seven treatments and three replications. The treatment media consisted of oil palm empty fruit bunch (LSTKKS), sawdust (SG), rice bran (DP), and CaCO₃ lime. The treatments were as follows: P1 (LSTKKS 1000 g + Lime 20 g), P2 (LSTKKS 800 g + SG 200 g + DP 100 g + Lime 20 g), P3 (LSTKKS 600 g + SG 400 g + DP 100 g + Lime 20 g), P4 (LSTKKS 500 g + SG 500 g + DP 100 g + Lime 20 g), P5 (LSTKKS 400 g + SG 600 g + DP 100 g + Lime 20 g), P6 (LSTKKS 200 g + SG 800 g + DP 100 g + Lime 20 g), P7 (SG 1000 g + DP 100 g + Lime 20 g). The parameters used in the study included mycelium growth on the substrate, incubation period until pinhead formation, number of pinheads, incubation period until fruiting body formation, number of fruiting bodies, fruiting body morphology, fresh weight of fruiting bodies, and dry weight of fruiting bodies. The results showed that mushrooms could grow on all treatment media, but the best growth and production occurred in treatments P4 with a dosage of 500 g oil palm empty fruit bunch + 500 g sawdust + 100 g rice bran + 20 g lime and treatment P5 with a dosage of 400 g oil palm empty fruit bunch + 600 g sawdust + 100 g rice bran + 20 g lime

AN IDENTIFICATION KEY FOR THE FRESHWATER SHRIMPS OF KEPULAUAN BANGGAI, SULAWESI TENGAH

2025-12-31T12:55:00+00:00

This study developed a key for identifying freshwater shrimp species collected from the Banggai Islands, Central Sulawesi, Indonesia. Such keys are essential tools for biodiversity studies and species identification, benefiting researchers, students, and institutions. Conducted between October 2023 and April 2024 at the Laboratory of Animal Biosystematics and Evolution (BSHE), the research utilized existing specimens from the Banggai Islands previously deposited and stored within the BSHE collection. Methodology comprised specimen sorting, sexing, photographic documentation, taxonomic identification, and subsequent construction of the dichotomous key. The resulting key encompasses two species within the family Atyidae (Caridina brevicarpalis and C. typus) and four species within the family Palaemonidae (Macrobrachium australe, M. equidens, M. lar, and M. latidactylus).

he title of this research is The observation of the growth and formation of white oyster mushroom fruit body (Pleurotus ostreatus) on sawsdust and cocoa leaf waste media litter which has been carried out in the Microbiology Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences. The aim of this research is to determine mycelium growth and formation. Fruting bodies of white oyster mushrooms (Pleurotus ostreatus) on a basic medium of sawdust substituted with leaf litter cocoa. This research was designed in a Completely Randomized Design (CRD) consisting of seven treatments and three replications. The treatment media consisted of sawsdust and and cocoa leaf waste (CLW), namely P1 (sawsdust 500g without CLW), P2 (sawsdust 475g + CLW 25g), P3 (sawsdust 450g + CLW 50g), P4 (sawsdust 425g + CLW 75g), P5 (sawsdust 400g + CLW 100g), P6 (sawsdust 375g + CLW 125g), P7 (sawsdust 350g + CLW 150g) 45g rice bran + 5g lime + 500 ml water were added to each treatment. The best growth in observing the mycelium incubation period until it filled the baglog was in treatment (P2) with a time of 43 days, the best growth in the incubation period until pinheads appeared was in treatment (P1) with a time of 53 days, the best treatment for the number or fruit bodies is in treatment (P5) with a value of 8,67, the best treatment for fresh body weight fruit, namely treatment (P5) with a value of 60,67g. The best treatment for fruit body dry weight was treatment (P5) with a value of 11,33g. The media composition corresponds to the best treatment of the seven treatments, namely P5 (400g sawdust + 100g cocoa leaf litter). Because it has the fastest fruit body incubation. The highest number of fruit bodies and the heaviest fresh weight and dry weight.
