Mangrove merupakan ekosistem utama pendukung kehidupan yang penting di wilayah pesisir dan lautan. Jenis-jenis mangrove di Desa Daiama khususnya Pulau Rote, pulau paling selatan Indonesia sampai saat ini belum diinventarisasi. Penelitian ini bertujuan untuk mengetahui struktur vegetasi mangrove dan pemanfaatannya di Desa Daiama, Kecamatan Landu Leko, Kabupaten Rote Ndao. Teknik pengumpulan data struktur vegetasi mangrove dilakukan dengan membuat peletakan sebanyak plot 16 pada 4 stasiun. Penempatan plot dilakukan dengan metode purposive sampling. Data pemanfaatan diperoleh dengan wawancara terhadap masyarakat Desa Daiama. Hasil penelitian yang diperoleh terdapat 11 jenis mangrove yang terdapat di Desa Daiama yang terdiri dari 6 family, antara lain: Rhizophoraceae (Rhizophora stylosa, Rhizophora mucronata, Ceriops spp, Ceriops tagal, Ceriops decandra, dan Bruguiera sexangula), Soneratiaceae (Soneratia alba), Lythraceae (Pemphis acidula), Myrsinaceae (Aegiceras floridum), Rubiaceae (S.hydrophylacea), Sapindaceae (Dodonaea viscose). Jenis mangrove yang paling dominan untuk tingkat pohon yaitu Rhizophora stylosa (89,54%), pancang yaitu Ceriops tagal (40,02%), dan tingkat semai Phempis acidula (59,09%). Indeks keanekaragaman vegetasi mangrove di Desa Daiama tergolong sedang pada setiap stasiun yaitu berkisar 1,67-2,00. Pemanfaatan mangrove di Desa Daiama tercatat dijadikan bahan obat, kayunya bahan bangunan dan pembuatan perahu, buah mangrove dijadikan bahan makanan, digunakan sebagai pewarna alami kain tenun.
Poisonous plants are plants containing a poison that can cause pain or death. The people of the Dawan Fatuleu Tengah tribe have used poisonous plants in their daily lives. However, these types of poisonous plants have not been well documented. The purpose of the present study was to determine the types of poisonous plants and their utilization by the Dawan Fatuleu Tengah tribe. The data collection was conducted by interviewing the respondents for the use of poisonous plants. The obtained results showed that eight types of poisonous plants from six families used by the Dawan Fatuleu Tengah tribe, namely arbila nuts (Phaseolus lonatus L.), tubaroot (Deris elliptica L.), cassava (Manihot esculent), sengon (Paraserianthes faltacataria L.), ginje (Thevetia peruvianan), kecubung (Datura metel L.), ceremai (Phyllanthus acidus L.), and biduri (Calotropis gigantean L.). The Dawan Fatuleu Tengah tribe community uses these poisonous plants to poison fish in the river for consumption, as a natural pesticide, to kill insect disease vectors, and for attacking the enemy. Abstrak Tumbuhan beracun merupakan tumbuhan yang mengandung racun dan dapat menyebabkan rasa sakit atau kematian. Masyarakat suku Dawan Fatuleu Tengah telah lama memanfaatkan tumbuhan beracun dalam kehidupan sehari-hari. Namun, sampai saat ini jenis-jenis tumbuhan beracun tersebut belum terinventarisasi dengan baik. Tujuan dari penelitian ini adalah untuk mengetahui jenis-jenis tumbuhan beracun dan pemanfaatannya oleh suku Dawan Fatuleu Tengah. Teknik pengambilan data berupa pengambilan sampel responden dapat dilakukan dengan menghimpun keterangan melalui wawancara tentang pemanfataan tumbuhan beracun. Hasil penelitian yang diperoleh menunjukkan bahwa terdapat 8 jenis tumbuhan beracun dari 5 famili yang dimanfaatkan suku Dawan Fatuleu Tengah yaitu kacang arbila (Phaseolus lonatus L.), akar tuba (Deris elliptica L.), ubi kayu (Manihot esculenta), sengon (Paraserianthes faltacataria L), ginje (Thevetia peruviana), kecubung (Datura metel L), ceremai (Phyllanthus acidus L), biduri (Calotropis gigantean L). Masyarakat suku Dawan Fatuleu Tengah memanfaatkan tumbuhan beracun tersebut untuk meracuni ikan di sungai untuk dikonsumsi, sebagai pestisida alami, untuk membunuh serangga vektor penyakit, dan juga untuk menyerang musuh.
East Nusa Tenggara (NTT) has the potential of local food natural resources that are useful in meeting the foodt needs of the NTT community such as corn, rice, tubers, local fruits and nuts. The purpose of this study was to inventory the types of tubers that have the potential as an alternative carbohydrate source in Amarasi Selatan District, Kupang Regency. The method used in this study is an exploratory method, which is done by exploring and observing directly the types of tubers found in the research location and conducting interviews. The data analysis technique in this study used a qualitative descriptive analysis technique, with the main objective of providing an objective description or description of a situation. Based on research that has been carried out in Amarasi Selatan District, Kupang Regency regarding the Inventory of tuber species that have the potential as an alternative carbohydrate source, it can be concluded that there are 7 types of tuber plants with 5 varieties, namely Cassava (Manihot esculenta Crantz) with 2 namely, Darul hidayah and Adira 1 varieties, sweet potato (ipomoea batatas) with 3 varieties, namely cilembu variety, muara takus variety and antin 2 variety, taro sweet potato (Colocasia esculenta), porang sweet potato (Amorphophallus Muelleri), Gembili sweet potato (Dioscorea esculenta). ), sweet potato (Dioscorea bulbifera), sweet potato (Canna Discolor). Tubers need to be cultivated properly so as not to become extinct and further research on pests that attack tubers.
Moringa leaf flour contains 14% protein, 40% calcium, and 23% iron, and is close to all toddlers' needs for vitamin A. Besides, Moringa leaves contain high antioxidants and antimicrobial properties, which causes moringa to function as a natural preservative. The aim of this study was to determine the effect of storage time on moisture content and total microbes in wet noodles substituted for Moringa leaf flour. The research method used was an experimental method with a completely randomized design. The variations in storage time are 0 hours, 6 hours, 12 hours, 24 hours, 30 hours, and 36 hours. Water content was tested using the oven method and total microbial testing using the Total Plate Count (TPC) method. Analysis of water content used the general formula for water content testing and total microbial analysis using the formula for calculating the number of colonies. The results showed the highest water content of moringa leaf flour substitution wet noodles at 36 hours of storage (2.53%). Meanwhile, the highest total of wet noodles with Moringa leaf powder substitution was at 36 hours of storage (> 300 CFU / g). Based on the research data, there is an effect on water content and total microbes in wet noodles substitution of Moringa leaf flour which increase with increasing storage time.
Wine is a drink made through the fermentation process of sugar in grapes which is then converted into alcohol. Apart from grapes there is another alternative for wine making, namely sorghum seeds. The starch content in sorghum seeds can be used in wine making. The purpose of this study was to determine the effect of fermentation time on alcohol content and level of preference for sorghum wine. This research was conducted at the Laboratory of Biological Education, Artha Wacana Christian University, Kupang, using the RAL experimental method with 4 treatments and 4 repetitions. Wine is made by mixing sorghum seed extract with yeast. The treatment of fermentation time in this study was P1 (7 days), P2 (14 days), P3 (21 days) and P0 / control (5 days). The resulting wine will be tested for alcohol content using an alcohol meter and an organoleptic test to determine the panelists' preference for sorghum wine. Data analysis using ANOVA and further Duncan / DMRT test. The results showed that the highest alcohol content was in the P3 treatment with an average of 8.75%. Overall, the parameters of taste, aroma and color have a significant effect. The data showed that the average panelists preferred the P3 treatment of taste (3,41), aroma (3,55), and color (3,38). Thus sorghum seeds can be an alternative ingredient in sorghum wine making.
