Dewasa ini upaya penemuan bahan hayati sebagai pupuk dan pembenah tanah dalam rangka meningkatkan produktivitas lahan marginal terus ditingkatkan. Seiring lahan subur makin sempit akibat alih fungsi ke non pertanian dan terdegradasi akibat penggunaan pupuk buatan secara intensif. Dampak buruknya tidak bisa diabaikan. Produktivitas tanah semakin menurun. Namun demikian dengan ditemukannya berbagai bahan hayati yang dapat dimanfaatkan sebagai sumber hara untuk tanaman sekaligus memperbaiki sifat kimia, fisika dan biologi tanah. Maka masalah tersebut dapat ditanggulangi. Perhatian terarah ke rumput laut coklat (Sargassum polycystum L.) yang secara ekonomis kurang menguntungkan sebagai bahan baku pangan fungsional. Jenis rumput laut ini dapat dimanfaatkan sebagai substrat menyubur tanah. Tujuan penelitian mempelajari pengaruh ekstrak rumput laut coklat sebagai sumber hara tanaman dan bahan padatnya sebagai amelioran tanah. Hasil penelitian menunjukkan bahwa ektrak berbahan rumput laut coklat dapat meningkatkan pertumbuhan dan hasil tanaman Timun yang diaplikasikan di tanah kering masam.

Making preparations for observing cells or tissues in practicum activities requires dyes. In cell biology practicum, especially observation of plant tissue in the Department of Biology Education, FKIP, Ambon University of Darussalam, it is still very limited, because it does not have chemical dyes for making preserved preparations. This is because chemical dyes are quite expensive, unsafe, and will spoil if stored for a long time, so it is very important to make natural dyes as a substitute for synthetic dyes so that the preserved preparations produced are safer, more affordable, and can be used for a long time. which is old. Sources of natural dyes are obtained from plant parts, for example: roots, bark, leaves, fruit, wood, seeds, and flowers. Turmeric (Curcuma domestica Val.) is a natural dye that can be used, because it is relatively cheap, easy to find, non-carcinogenic, and biodegradable. The active pigments in turmeric which can color plant tissue and give it a yellow color are curcuminoids. The aim of this research was to study the utilization of turmeric extract (Curcuma domestica Val.) as a natural dye for preparing preserved preparations of plant tissues in cell biology practicum. This type of research is experimental research, which has several stages of research including: observation, preparation, research implementation, and analysis stage. At the data analysis stage, a qualitative descriptive method was used to determine the quality of the preserved preparations. The quality of the preparations in this study was expressed by the percentage of eligibility of ≥ 62.5% or feasible criteria. The results showed that the average percentage of the quality of the preparations that had been validated was 66.96% and 67.85% with proper criteria. This shows that the preserved preparations made are suitable for observing plant tissues in cell biology labs.

Abstract. Kamsurya MY, Bontari S, Kamaruddin, Hulopi F, Lahabi M, Djumati JL. 2023. Role of soil parameters in forest clove (Syzygium obtusifolium) habitat and their effects on phenology and production. Biodiversitas 24: 4910-4918. Forest cloves (Syzygium obtusifolium L.) are a type of non-aromatic clove that originally grew wild and are now starting to be cultivated. This study aimed to examine role of soil chemical and physical parameters in clove plant habitat and their influence on flowering phenology and production. The experiment was carried out on the island of Ambon Maluku, for a duration of 17 months from January 2020 - May 2021. A survey was conducted on forest clove plant cultivated by farmers aged between 10-15, and five observation locations were selected using the purposive sampling method. Soil analysis was performed at the Laboratory of Soil Science, Faculty of Agriculture, University of Hasanuddin Makassar, while observational data were analyzed using principal component regression analysis (PCRA). The results showed that soil chemical parameters contributed 14.89% to forest clove plant habitat, with the N and Ca content providing the highest contribution of 3.49% and 3.26% respectively. The contribution of physical parameters amounted to 8.09%, with sand particles exhibiting the highest value of 2.43%. Furthermore, PCRA results found that soil chemical parameters influenced the phenology of forest clove flowering by 21.8%. The relationship between the independent variables (X1 to X5) and flowering phenology (Y) had a correlation (R) of 0.47, while the physical parameters exerted an influence reaching 79.4% with an R-value of 0.89. The average production of fresh and dry clove flowers from forest clove plant was 50.3 and 20.1 kg/plant, respectively.
