During this time, the remaining milk that has been consumed only wasted. Milk content is strongly associated with nutrients to increase crop productivity. This requires innovations in the manufacture of organic fertilizer products. The purpose of this study was to determine the best composition comparison between stale milk, EM4 solution and cocopeat in the process of making liquid and solid organic fertilizer and determine the c-organic value, Ntotal, P2O5total, K2Ototal, and pH value. Initial analysis of liquid organic fertilizer obtained pH values of 5.10, P2O5total Â of 0.342% and Ntotal of 0.569% at initial control (stale milk only) and final values of 1.010% ofÂ P2O5total, 1.113% of Ntotal and 10.480% of organic carbon in R3 ( 30: 5: 1). Initial analysis of solid organic fertilizer obtained pH values 5.26%, 2.668% P2O5total, 0.952% K2Ototal and 2.780% Ntotal at R1 (10: 5: 1) and final values obtained 1.578% P2O5total at R1 (10: 5: 1) , 2.937% Ntotal in R2 and 43.912% carbon organic in R3. This shows that stale milk with the addition of EM4 and cocopeat solutions has an effect on phosphorus and nitrogen nutrients in liquid and solid organic fertilizer.

Fertilizer is a nutrient that is the main need for plants. One of the organic materials that is widely used as organic fertilizer is chicken manure which can have an influence on the availability of nutrients and improve the structure of soil which is very deficient in organic nutrients and can also fertilize plants. One of the dry leaves that has the potential to be used as organic fertilizer is ketapang leaves, which have a C-Organic nutrient content of 60.32%; N-Total 0.55 % ; P-Total 0.14 % ; K-Total 0.20%. In addition, the nutrient content of chicken feces is N 1%; P 0.80% ; K 0.40% and water content 55%. The wood powder content consists of chemical components such as cellulose, hemicellulose, lignin and extractive substances. This research method uses a completely randomized design, consisting of 5 treatments of various raw material compositions of chicken manure, dry ketapang leaves and wood dust. The ratio of the use of organic fertilizer and soil is 50: 50. This research aims to determine the height growth and number of leaves for cayenne pepper based on from various raw material compositions of chicken manure, ketapang leaves and wood dust. This research consisted of 5 treatments of various raw material compositions of chicken manure, dry ketapang leaves and sawdust. The ratio of organic fertilizer and soil was 50: 50. The results from observing plant height were that P1 was 6 cm high and the highest number of leaves on P2 was 7 pieces. However, the addition of organic fertilizer with various compositions does not have much effect on the growth of cayenne pepper seeds.

Penggunaan karbon aktif (activated carbon/AC) semakin luas seperti untuk reaksi kimia, adsorpsi limbah cair dan gas, serta sebagai katalis dalam proses katalitik. AC-tempurung nipah dan AC-kulit pisang kepok telah disintesis dengan aktivator kalium hidroksida (KOH) 0,5 M. Karbonisasi dilakukan dengan furnace pada suhu 300 °C selama 2 jam. Karakterisasi AC dilakukan dengan analisis kadar air, analisis kadar abu, analisis daya serap I2, dan analisis gugus fungsi sebelum proses aktivasi dan setelah proses aktivasi menggunakan FTIR. Nilai kadar air, kadar abu, daya serap terhadap I2berturut-turut adalah 1% ; 9,9%; 1307 mg/g (AC-tempurung nipah) dan 3% ; 7,4% ; 1777 mg/g (AC-kulit pisang kepok), memenuhi kriteria karbon aktif yang telah ditetapkan SNI. Hasil spektra FTIR AC-tempurung nipah dan AC-kulit pisang kepok menunjukkan adanya pergeseran bilangan gelombang serapan gugus -OH setelah aktivasi. Serapan gugus C=C aromatik mengindikasikan telah terbentuknya grafit.

River water pollution in Cilacap Regency is caused by industrial activities related to oil refining and river crossing traffic, which generate wastewater containing Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), and heavy metals such as lead. This study aims to evaluate the performance of biomass-based activated carbon—derived from coconut fronds and laban wood sawdust—in river water purification through physicochemical characterization and adsorption kinetics approaches. The activated carbon was characterized according to the Indonesian National Standard (SNI) 06-3730-1995, and its surface area was analyzed using the Brunauer–Emmett–Teller (BET) method. Characterization results for AC-PK 1(100) showed a moisture content of 0.1085%, ash content of 3.05%, iodine adsorption capacity of 571 mg/g, and a surface area of 110.595 m²/g. The adsorption process after 15 minutes demonstrated that the activated carbon was effective in reducing water quality parameters, with the pH reaching neutral (7) and TSS decreasing to 212 mg/L, meeting Class III standards based on Government Regulation No. 82 of 2001. However, the TDS value of 4690 mg/L did not meet the quality standard. Kinetic studies indicated that the first-order reaction model best described the adsorption mechanism, with R² values approaching 1. The adsorption rate constants were 0.0041 min⁻¹ for TSS and 0.0686 min⁻¹ for TDS. These findings suggest the potential application of biomass waste as a raw material for activated carbon in environmentally friendly river water purification technologies.

Indonesia is a country with the highest biodiversity, especially in mangrove ecosystems, with a total of around 89 species. The mangrove ecosystem includes Rhizophora (mangrove), Avicennia (api-api), Sonneratia (pedada), Bruguiera (tanjang), and Xylocarpus (nyirih). Mangrove propagules are the fruits of mangroves in the form of hypocotyls that function to store food when the propagules germinate and grow. Secondary metabolites from plants have bioactivity, so it is important to identify them using specific reagents known as phytochemical screening. The group of secondary metabolite compounds is classified based on their chemical structure, consisting of flavonoids, tannins, phenols, alkaloids, steroids, and triterpenoids. This study aims to determine the content of flavonoid, tannin, and phenol compounds in Bruguiera sp. propagules. The method for extracting tannins, phenols, and flavonoids from mangrove propagules can be performed using the Microwave Assisted Extraction (MAE) method. The raw material is 3 kg of Bruguiera sp. mangrove propagules from Kutawaru Village, which are then cut into small pieces and dried using an oven at 105°C for 3 hours, subsequently ground, and sieved with a 60 mesh size. The extraction process of the mangrove propagule powder was weighed at 15 grams using 250 ml of ethanol as the solvent. The results of the phytochemical test on the Bruguiera sp. mangrove propagule extract were positive for flavonoids, tannins, and phenols.
