Abstract

Sukun (Artocarpus altilis Parkinson ex F.A.Zorn) yang ada di Indonesia umumnya adalah tanpa biji. Sehingga sangat sulit untuk dikembangkan secara generatif dengan biji. Alternatifnya adalah dengan perkembangbiakan secara vegetatif dengan setek. Faktor penting untuk menjamin kelangsungan hidup suatu setek adalah pembentukan tunas dan akar yang dapat dirangsang dengan zat pengatur tumbuh (ZPT). Salah satu ZPT alami yang dapat digunakan utuk merangsang pertumbuhan akar dan setek adalah ekstrak bawang merah. Penelitian ini adalah untuk mengetahui lama perendaman ekstrak bawang merah terhadap pertumbuhan akar dan tunas setek batang sukun Pengambilan bahan setek sukun dilakukan di kawasan Desa Madapolo, Kecamatan Obi, Kabupaten Halmahera Selatan, Provinsi Maluku Utara. Perlakuan yang diterapkan adalah perbedaan lama perendaman bahan setek batang sukun ke dalam larutan ekstrak bawang merah. Lama perendaman yang diterapkan sebanyak 4 perlakuan, yaitu: 0 menit (kontrol), 10 menit, 20 menit, dan 30 menit. Pengamatan pertumbuhan tunas setek dilakukan selama 12 minggu dan pengamatan akar dilakukan pada akhir pengamatan. Hasil pengamatan menunjukkan bahwa lama perendaman ZPT alami ekstrak  bawang merah berpengaruh terhadap pertumbuhan tunas dan akar setek. Jumlah tunas terbanyak pada perlakuan tanpa perendaman ekstrak bawang merah, sedangkan panjang tunas yang tertinggi adalah pada perlakuan perendaman ekstrak bawang merah selama 30 menit, demikian pula untuk jumlah dan panjang akar.

Abstract

Jelutung is a tree species of the family Apocynaceae that is famous for its latex use as material for chewing gum. In Indonesia there are two species, namely jelutung land (Dyera costulata) and jelutung swamp (Dyera polyphylla). Until now, information on the differences in the two types of jelutung morphology is still very limited. There is therefore the need for a study on the variation of both types cultivated. This study was conducted to estimate variations in leaf morphology for land and swamp jelutung to assess 14 variables of its leaf morphology. Results of multivariate analysis (PCA, MCA, and CDA) showed that jelutung can be classified into two groups: D. costulata and D. polyphylla. PCA and MCA showed three variables that most distinguishes the two types of jelutung consecutive leaf length (PL), Roving Leaf (KL) and the shape of apex (AS). The CDA variables that play a major role in the classification of Dyera are the shape of apex (AS), the form of the base of the leaf (BS), leaf vein angle (SD).

Abstract

Cocoa is a rich source of essential minerals and contributes a significant amount of minerals in the human diet. Processed products from cocoa in the form of chocolate are in great demand by almost everyone from various statuses and social groups. The high consumption of chocolate is also not a fact that chocolate is beneficial to human health. The essential minerals (Mn and Zn) in cocoa beans are needed by the human body as a source of minerals, but if excess can be harmful to the body. The purpose of this study was to determine the content of essential trace elements in cocoa beans and their potential as raw materials for food products. The analysis method uses AAS (Atomic Absorption Spectrophotometry). The results showed the content of micronutrients (Mn and Zn) in cocoa beans at five location points with an average value of 0.8976 mg/100 g and 5.7534 mg/100 g.

Abstract

Merbau is a type of tree whose wood is classified as durable with durable class I-II and strong class I-II. Because of this durable and strong class, merbau wood is widely used in industry. This research was conducted with the aim of testing the effect of invigorating merbau seeds using matriconditioning and osmoconditioning methods. The study was conducted using a completely randomized design (CRD) with 6 levels of treatment, namely control, sawdust, husk charcoal, PEG, NaCl and KNO3. The research data were tested using ANOVA and Duncan's follow-up test. The results of the study. The results showed that invigoration treatment could increase the viability of merbau seeds on the observed variables of root length, height, and number of leaves. Of all the invigoration treatments, the best material in increasing the viability of soybean seeds was the matriconditioning treatment using sawdust.
