Abstract

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.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian larutan tembaga terhadap pertumbuhan tanaman bunga matahari (H. annuus L.). Penelitian ini dilakukan dengan menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari 4 konsentrasi perlakuan logam Cu yaitu P0: 0 mg/L, P1: 100 mg/L, P2: 200 mg/L dan P3: 500 mg/L, dengan 5 ulangan untuk setiap perlakuan sehingga didapatkan 20 sampel tanaman. Penelitian ini dilakukan dengan merendam biji bunga matahari kultivar dalam wadah berisi air hangat selama semalam kemudian ditanam pada polybag. Tanaman dipelihara secara intensif hingga berumur 2 minggu setelah tanam dan dilakukan aplikasi Cu. Logam Cu yang digunakan berupa garam CuSO4.5H2O. Pemberian larutan Cu dilakukan setelah tanaman mengalami aklimatisasi selama 1 minggu (tanaman berumur ± 5 minggu). Cu yang diaplikasikan berupa garam CuSO4.5H2O yang mengandung kurang lebih 25% ion Cu. Garam tersebut dilarutkan dalam aquades sebanyak 1L sesuai konsentrasi dan diberikan 4 kali dalam jangka waktu 2 minggu hingga larutan Cu habis. Larutan Cu sebanyak 250 ml disiramkan ke tanah disekitar tanaman secara hati-hati agar tidak kontak langsung dengan batang tanaman. Pada perlakuan kontrol tidak dilakukan penyiraman garam CuSO4.5H2O. Setelah pemberian Cu, dilakukan pengamatan dan pengukuran parameter pertumbuhan. Parameter pertumbuhan terdiri dari tinggi tanaman, jumlah daun, dan panjang akar tanaman. Data hasil pengamatan disajikan dalam bentuk gambar dan pengukuran akan dianalisis menggunakan analisis sidik ragam (ANAVA) dan diuji lanjut dengan DMRT (Duncan Multiple Range Test) dengan tingkat kepercayaan 95%. Hasil penelitian menunjukkan bahwa pemberian larutan Cu berpengaruh terhadap pertumbuhan tanaman bunga matahari. Semakin tinggi konsentrasi Cu mengakibatkan terhambatnya tinggi tanaman, penurunan jumlah daun, dan terhambatnya pemanjangan akar tanaman.

Abstract

This research aims to describe the scientific literacy abilities of students at SMP Negeri 21 Central Maluku class VIII on photosynthesis material using the LOK-R learning model. This study is part of a study on developing learning tools to improve scientific literacy skills. Diagnosis of students' scientific literacy abilities is measured through initial and final test instruments in the form of multiple choice questions and essays. The diagnosed scientific literacy abilities are students' scientific literacy abilities before and after the LOK-R learning model is implemented which is thought to be able to develop students' scientific literacy abilities. This research includes quantitative descriptive research. The subjects of this research were 28 class VIII students of SMP Negeri 21 Central Maluku. The data collection method used is the test and questionnaire method. The data analysis technique uses quantitative descriptive analysis which refers to AKMI, 2015. The research results show that the achievement of students' scientific literacy abilities and science skills after the learning process using the LOK-R model is 100% above the 2015 EOCD target, namely above 40%. Thus, it can be concluded that the LOK-R learning model is good for developing students' scientific literacy skills.

Abstract

This study aims to determine the effectiveness of the brown algae extract Padina australis in inhibiting the growth of Bacillus cereus and Eschericia coli bacteria. Samples were taken from the waters of Osi Island, West Seram, Maluku Province as much as 1 kg, the sample was then dried using the sundrying method. The dried sample was then soaked for 24 hours and extracted. The extract results were then tested for phytochemicals and antibacterial activity tests carried out in the Microbiology Laboratory of Pattimura University, Ambon. The results showed that (1) The brown algae extract Padina australis contains secondary metabolites in the form of flavonoids, terpenoids, steroids, saponins and alkaloids; (2) The combination of these various compounds provides a synergistic effect that can increase the effectiveness of antimicrobials in inhibiting the growth of Bacillus cereus and Escherichia coli bacteria; (3) The minimum inhibitory concentration (MIC) of Padina australis algae extract has different abilities in inhibiting test bacteria. The MIC of Bacillus cereus bacteria at a concentration of 10% has an inhibition zone of 7 mm and the MIC of Escherichia coli bacteria at a concentration of 60% has an inhibition zone of 11 mm.

Abstract

The purpose of the study is to determine the optimal concentration of rabbit urine administration (POC Rabbit Urine) to increase the growth and yield of curly chili plants (Capsicum annum L.). This type of research is experimental research. This research was carried out in the Experimental Garden of the Faculty of Agriculture, Unidar Ambon, at an altitude of 150 m above sea level, the average daily temperature is around 27-290C.  The experiment will be carried out from February to May 2024. Variables observed on growth components and plant yield components include, plant height, number of leaves, the number of branches, when flowers appear, the number of harvested fruits, the total weight of the fruit of the plant. Observations are made after the plants are 1 week old after planting. The data obtained was analyzed using a variety fingerprint (F test) at the level of 5%. If the real influence is continued, the Smallest Real Difference Test (BNT) is continued. The results showed that the POC treatment of rabbit urine had a real effect on the control of all observed variables. Rabbit urine concentration of 300 ml/L of water resulted in the highest number of harvested fruits and fruit weight compared to other treatments.
