This study aims to determine land suitability class for of plantation crops, namely, coconut, clove, and cocoa in Galela region, North Halmahera, North Maluku
South Halmahera is one of the cocoa-producing centers in North Maluku, but the pulp of cocoa is less noticed and assumed to be not important in commercial purpose and is largely disposed as agroindustry residue. This study aimed to characterize the cocoa pulp from southern Halmahera for bioethanol production. Survey and observation methods were conducted to obtain bioethanol feedstock from cocoa pulp. Cocoa pulps mucilage is a waste that can be processed into bioethanol products with high economic value. The results of this study indicated that theaverage of 100kg of cocoa beans produced 5-8 litters of mucilage juice residues. The results of this study indicated that cocoa pulp from southern Halmahera had the optimum time for the fermentation process for 12 days. The level of alcohol produced by fermentation was 4.85%, and this level was a low category.
Inceptisol Ternate adalah tanah yang memiliki Carbon organic (C organik), Nitrogen total (N total), Fosfor total (P total) dan Kapasitas Tukar Kation (KTK) tanah yang rendah, oleh sebab itu harus di barengi dengan tindakan pemupukan. Tujuan penelitian ini untuk mengetahui pengaruh pemberian pupuk kandang kambing di tanah inceptisol terhadap pertumbuhan dan hasil tanaman caisim. Rancangan yang digunakan pada penelitian ini adalah Rancangan Acak Kelompok (RAK) dengan perlakuan pemberian pupuk kandang kambing, yang terdiri atas 5 tingkat, yaitu: H0 = kontrol (tanpa pupuk), H1 = 10 ton ha-1, H2 = 20 ton ha-1, H3 = 30 ton ha-1, dan H4 = 40 ton ha-1, masing-masing diulang 4 kali. Hasil penelitian menunjukkan pemberian pupuk kandang kambing di tanah inceptisol memberikan pengaruh yang nyata (p>0,05) terhadap tinggi tanaman caisim pada umur 10 hari setelah tanam, namun pada umur 20 dan 30 tidak berpengaruh nyata, demikian pula untuk jumlah daun, luas daun, berat segar, persen kadar air dan pH tanah pengaruhnya tidak nyata. Produksi tertinggi dicapai pada perlakuan dosis pupuk kandang kambing 40 ton ha-1 yakni 13,25 ton ha-1 sedangkan terendah pada kontrol yakni 5,75 ton ha-1.
Nutmeg plant is one of the spice commodities that had been known from the ancient world. In an effort to revive the dignity of spice crops, nutmeg also promise encourage to be developed. This study aims to analyze the effect of cow manure and KCl to change soil properties and growth of nutmeg in inceptisol Galela in North Halmahera district-part of North Maluku province. The research was conducted on mixed cropping system, by using factorial experiment in randomized block design which consisted of two factors. The first factor was the manure application that consisted in three levels: without manure, 500 kg ha-1 of manure, and 1000 kg ha-1 of manure. The second factor was K fertilizer application, consisted of four levels: without KCl, 60 kg ha-1 of KCl, 120 kg ha-1 of KCl, and 180 kg ha-1 of KCl. The results showed that the separately application of 500 kg ha-1 of cow manure or 120 kg ha-1 of KCl fertilizer are a suitable dosage to influence nutmeg grown in mixed garden.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
