Abstract

ABSTRACTMahogany (Swietenia macrophylla) plantations are threatened by shoot borer (Hypsiyla robusta), therefore the resistance of mahogany plants to shoot borer become a priority for the establishment of mahogany plantations. Elite trees that have resistance to shoot borer could be found through genetic selection of mahogany population in the field.  Propagation of these elite trees should be prepared by vegetative propation to ensure that the mother plant’s characteristics were inherited. Vegetative propagation of mahogany was conducted by cuttings. The experiment design consisted of split plot in randomly group with 4 medias and 3 IBA treatments; repeated 3 groups with 15 seedlings per experimental unit. Cutting materials were collected from one year old seedlings. Successful cutting was determined by these parameters: percentage of rooted cuttings, numbers of root, root length, shoot length, root biomass, and shoot biomass. The results showed that media factor had significant effect to cuttings, while soaking cutting material in growth regulators gave no significant effect. The highest percentage of rooted cutting was produced by media cocopeat+husk (2:1, v/v) by 93%. The greatest number of roots were generated using rice husk and coconut+husk (2:1, v/v) by 4.5 strands of roots. The longest root was produced using media soil by length 86 mm. Based on these cutting parameters, cocopeat+husk is the most optimal media for mahogany cuttings.Keywords: cuttings, mahogany, rooting media ABSTRAKPenanaman mahoni terancam oleh serangan hama penggerek pucuk Hypsipyla robusta, sehingga pencarian mahoni yang memiliki sifat resisten menjadi prioritas dalam pengembangan mahoni. Seleksi genetik dari populasi mahoni di lapangan yang terbukti memiliki ketahanan terhadap Hypsipila adalah salah satu cara untuk memperoleh pohon unggul mahoni. Perbanyakan bibit dari pohon unggul harus dilakukan secara vegetatif agar anakan memperoleh sifat unggul dari induknya. Pada penelitian ini, perbanyakan vegetatif pada spesies mahoni (Swietenia macrophylla) telah dilakukan dengan cara stek pucuk. Rancangan penelitian menggunakan split plot dalam rancangan acak kelompok dengan petak utama jenis media yang terdiri atas 4 jenis media, anak petak konsentrasi zat pengatur tumbuh yaitu 3 konsentrasi IBA, dan dikelompokan menjadi 3 kelompok. Bahan stek diambil dari pucuk anakan umur 1 tahun. Keberhasilan stek pucuk dilihat dari parameter persentase berakar, jumlah akar, panjang akar, panjang tunas, biomassa akar, dan biomassa pucuk. Faktor media berpengaruh nyata terhadap proses stek, sedangkan pemberian IBA dengan cara perendaman basal tidak memberikan pengaruh nyata. Persentase berakar  tertinggi dihasilkan dari media campuran sabut kelapa+sekam (2:1, v/v) sebesar 93% atau lebih tinggi 16% dibandingkan media kontrol (tanah). Jumlah akar terbanyak dihasilkan dari media arang sekam dan campuran sabut kelapa+sekam (2:1, v/v) sebanyak 4,5 helai atau naik sebesar 47% dibandingkan kontrol. Panjang akar tertinggi dihasilkan oleh kontrol (media tanah) dengan nilai 86 mm. Berdasarkan parameter pertumbuhan stek, media sabut kelapa+sekam (2;1, v/v) merupakan media yang paling optimal untuk stek pucuk mahoni.Kata kunci: mahoni, media perakaran, stek pucuk

Abstract

 The use of chemical pesticides is often carried out in excessive doses, so that this condition results in increased accumulation of pesticide residues in nature. The residue can kill non target organisms, there was an explosion of secondary pests and pest resistance. One effort to reduce the use of synthetic chemical pesticides is by substitution using botanical pesticides that are more environmentally friendly. Botanical pesticides that are easily biodegradable in nature, so it does not pollute the environment, it is relatively safe for humans and the presence of natural enemies. One of the most potential types of botanical pesticides is from the Meliaceae family, namely neem, mahogany, and suren. In this study, the content of secondary metabolites was tested for neem, mahogany and suren seeds. Toxicity properties against pests conducted through literature searches. The purpose of this study was to obtain information on the toxicity and content of secondary metabolite compounds from the three plant seed extracts against forest pests. The results showed that the extract of neem, mahogany and suren seeds contain compounds secondary metabolites from the saponins, tanins, flavonoids, alkoloids, and terpenoids. The compounds can be used as botanical pesticides to control pests of forest plants.

Abstract

Insects have an important role for human life, both negative and detrimental roles as well as positive or beneficial roles. The role of harmful insects is as pest, while the beneficial role can be used as an alternative food source. In some areas in Indonesia, insects are also consumed as food, unfortunately there are still many people who consider insects not suitable for consumption, making the potential possessed by insects not fully utilized. This paper aims to provide information on the types of insects that can be a source of food, as well as the nutritional value contained in insects. Commonly consumed insects are termites, teak caterpillars, sago caterpillars, grasshoppers, and crickets. The insects contain high enough of nutrition that is expected to be used as alternative food source to meet community nutritional needs
