Abstract

The purpose of this study was to analyze the diversity of weed species in corn plantings in the Usaha Maju Farmer Group, Naibonat Village, East Kupang District, Kupang Regency which took place from July to December 2020. Observation of weeds was carried out using the quadratic method. Observations in the sample plots by making observation subunits measuring 1 x 1 m2. Unknown weed species were collected and then identified using the Plant Snap application and making a herbarium. The results showed that there were 13 weed species found associated with corn plants, namely Eleusine indica, Setaria pumila, Echinochloa colona, Cynodon dactylon, Digitaria ciliaris, Xanthium strumarium, Centela asiatica Ipomoea obscura, Euphorbia hirta, Tridax procumbens, Spigelia anthelmia, Passiflora foetida, and Phyllanthus niruri. Based on vegetation analysis, Eleusine indica and Euphorbia hirta were more dominant than other weed species with absolute densities of 20.5m2 and 21.3m2 per maize plant, respectively.

Abstract

South Central Timor Regency, especially the South Coastal part, is an area with a dry climate which is an optimal area for the growth of the genus Ficus. Previous research data shows that on Timor Island there are 25 types of Ficus out of 252 species found in Indonesia. However, this data is not based on the results of field research, but from the results of reviews of other studies. Therefore, the purpose of this study was to identify the types of plants of the Ficus genus found on the South Coast of South Central Timor and determine the level of species diversity. The method used in this study is the exploratory method by exploring each coastal habitat, rivers, rocky hills or steep slopes, agricultural land, settlements and forests. To determine the type of Ficus, it was identified based on the criteria of Berg & Corner (2005) while the level of species diversity was determined based on the Shannon Wiener diversity index. The results showed that on the South Coast of Timor Tengah Selatan there were 956 individuals consisting of 19 species of Ficus and 3 of them namely Ficus callophylla, Ficus drupacea and Ficus microcarpa which had never been reported on the island of Timor. The level of species diversity is included in the moderate category, this is because only a few species dominate.

Abstract

Wilayah Pesisir Selatan Kabupaten Timor Tengah Selatan merupakan wilayah yang tergolong kritis karena sebagian wilayahnya telah berubah menjadi areal pertanian tebang bakar sehingga memerlukan prioritas rehabilitasi. Salah satu upaya rehabilitasi adalah dengan menggunakan metode spesies kerangka dengan genus Ficus sebagai jenis kerangka yang direkomendasikan. Oleh karena itu, tujuan dari penelitian ini adalah untuk mengetahui sebaran geografis spesies Ficus dan potensi pemanfaatannya sebagai jenis kerangka rehabilitasi hutan dan lahan di pesisir selatan Kabupaten Timor Tengah Selatan Provinsi Nusa Tenggara Timur. Metode yang digunakan dalam penelitian ini adalah metode survei lapangan dan survei wawancara. Survei lapangan dilakukan dengan cara menjelajahi setiap habitat tanaman Ficus yang terdiri dari kawasan hutan, kawasan pemukiman, lahan pertanian dan persawahan, sabana, semak belukar dan daerah sempadan sungai, kemudian setiap tanaman Ficus yang ditemukan kemudian dicatat jenis dan koordinatnya serta habitat tempat ditemukannya menggunakan GPS. Sementara itu, survei wawancara dilakukan dengan menggunakan teknik snowball sampling . Data sebaran jenis Ficus kemudian dipetakan menggunakan QGIS. Hasil penelitian menunjukkan bahwa jenis Ficus yang teridentifikasi di lokasi penelitian di wilayah pesisir selatan Kabupaten Timor Tengah Selatan sebanyak 19 jenis dari 956 individu yang ditemukan dengan sebaran geografis masing-masing jenis cukup beragam berdasarkan wilayah administrasi penelitian, penggunaan lahan, luas kawasan hutan, kemiringan lereng dan kekritisan lahan. Jenis-jenis Ficus yang dijadikan jenis kerangka acuan konservasi hutan dan lahan adalah Ficus benjamina , Ficus septica , Ficus racemosa , Ficus callosa , Ficus virens , Ficus variegata , dan Ficus nervosa subsp. pubinervis .

Abstract

Reclamation of ex-mining land is an obligation that must be carried out by every mining business actors, in order to organize, restore, and improve the quality of the environment and ecosystem so that it can function again according to its designation. However, this obligation has not been carried out consistently by manganese mining companies in West Timor. Based on the results of supervision carried out by mining inspectors, no company has carried out reclamation. This study aims to identify factors that influence the implementation of reclamation governance for ex-mining manganese land in West Timor. Case studies were conducted on eigth location of Izin Usaha Pertambangan (IUP) in West Timor, East Nusa Tenggara Province. Data collection was carried out through questionnaires, interviews, and field observations. Furthermore, data analysis used qualitative descriptive methods. The results of the study indicate that the inhibiting factors for achieving successful reclamation of ex-mining land in West Timor are the licensing process, supervision, competence of mining business actors, and community involvement. In this regard, further research is needed to examine the form of reclamation that is in accordance with the conditions of ex-mining manganese land in West Timor.
