Tomato is an important crop in Ternate, North Maluku Province, Indonesia. This study aimed to determine the irrigation water requirements for tomato cultivation on Regosol soil in the North Ternate region using the CROPWAT 8.0 model. Climate data, crop data, and soil data were collected and processed using the CROPWAT 8.0 program. The results showed that the irrigation water requirements varied significantly between the rainy and dry seasons. During the rainy season, the total irrigation water requirement ranged from 60 to 107 mm, while in the dry season, it was much higher, ranging from 130 to 187 mm. This difference was primarily due to the low rainfall during the dry season. Simulations of planting at different periods showed relatively minor variations in crop water requirements, reflecting the stable weather conditions throughout the year in Ternate. The findings of this study can assist local tomato farmers in managing irrigation water more efficiently and effectively, thereby improving crop productivity and reducing the risk of water shortage.

Penelitian “Pengaruh penambahan kafein pada sperma kauda epididimis sapi Bali pasca thawing terhadap jumlah oosit yang terfertilisasi telah dilakukan selama 10 bulan. Koleksi testis diambil dari Rumah Potong Hewan (RPH) Cibinong, proses pembekuan sperma epididimis dilakukan di laboratorium Unit Rehabilitasi Reproduksi (URR), Departemen Reproduksi dan Pathologi, Fakultas Kedokteran Hewan Institut Pertanian Bogor, analisis sperma beku pasca thawing dilaksanakan di laboratorium Reproduksi, Pemuliaan dan Kultur Sel Hewan, Puslit Bioteknologi LIPI Cibinong dan proses fertilisasi in vitro (IVF) dilaksanakan di Balai Embrio Ternak (BET) Cipelang Bogor. Tujuan penelitian ini untuk mengukur fertilitas sperma kauda epididimis pasca thawing dengan penambahan kafein pada keberhasilan in vitro fertilisasi (IVF). Metode penelitian ini adalah koleksi sperma kauda epididimis di RPH. Analisis kualitas sperma kauda epididimis pasca thawing dilakukan dengan perlakuan penambahan kafein T0 (0 mg/ml), T2 (2 mg/ml), T4 (4 mg/ml), dan T6 (6 mg/ml) dengan 4 kali ulangan. Parameter utama yang dianalisis adalah fertilitas sperma kauda epididimis secara in vitro fertilisasi. Rancangan yang digunakan adalah Rancangan Acak Lengkap (RAL) satu arah dan dilanjutkan uji Tukey-W-Procedure dengan SPSS 16. Hasil penelitian menunjukkan bahwa fertilitas sperma kauda epididimis pada T2 dan T4 berbeda nyata lebih tinggi (P0,05) dibandinngkan dengan T0 dan T6. Kesimpulan penelitian ini adalah keberhasilan oosit terfertilisasi secara in vitro pada sperma kauda epididimis pasca thawing dengan penambahan kafein 4 mg/ml adalah 37,50%.

Abstract Termites, which are destructive pests for both plants and wooden structures, pose a significant threat to humans. In Indonesia, termite attacks result in estimated annual economic losses of 1.67 trillion rupiah. To address this issue, effective termite control measures are essential. This study investigates the efficacy of poison extracted from jung rahab (Baeckea frutescens L.) against termites. The research employed an experimental approach with a completely randomized design (CRD), including two treatments and five replications. Concentrations tested were 10%, 15%, and 20%. Results revealed the highest retention value at 0.03494 g for the 10% concentration. However, this value remains below the SNI 01-5010.1-1999 standard. A 10% solution of Jung Rahab leaf extract significantly reduced termite mortality by 98.4%. All concentration treatments led to decreased weight in test samples compared to the control, indicating the inhibitory effect of Jung Rahab leaf extract on termite consumption. Solutions with concentrations of 10%, 15%, and 20% effectively suppressed termite feeding rates. Key words: Termites, extract, retention, mortality Abstrak Rayap merupakan salah satu jenis hama tanaman dan perusak kayu bangunan yang merugikan manusia. Kerugian ekonomis akibat serangan rayap di Indonesia diperkirakan mencapai 1,67 triliun rupiah per tahun. Oleh karena itu, pengendalian rayap menjadi suatu keharusan. Penelitian ini bertujuan untuk menentukan efektivitas racun dari ekstraksi jung rahab (Baeckea frutescens L.) terhadap rayap. Metode penelitian menggunakan desain eksperimental acak lengkap (CRD) dengan 2 perlakuan dan 5 ulangan. Variasi konsentrasi yang digunakan adalah 10%, 15%, dan 20%. Hasil penelitian menunjukkan bahwa nilai retensi tertinggi yang diperoleh adalah 0,03494 gram pada konsentrasi 10%. Namun, nilai retensi ini masih sangat rendah karena belum memenuhi standar SNI 01-5010.1-1999. Pemberian larutan ekstrak daun Jung Rahab (Baeckea frutescens L.) dengan konsentrasi 10% mampu mengurangi mortalitas rayap hingga 98,4%. Seluruh perlakuan konsentrasi mengalami penurunan berat contoh uji dibandingkan dengan kontrol. Hal ini menunjukkan bahwa larutan ekstrak daun Jung Rahab pada contoh uji mampu menghambat kemampuan rayap dalam mengonsumsi contoh uji. Kata Kunci: rayap, ekstrak, retensi, mortalitas
