Abstract

Pemanfaatan kepiting bakau (Scylla spp.)  oleh masyarakat setempat khususnya nelayan di wilayah pesisir Timur Bangka Tengah cukup intensif. Penelitian ini bertujuan menganalisis keanekaragaman dan kelimpahan kepiting bakau, parameter Fisik-Kimia perairan, kerapatan mangrove serta saling keterkaitannya di pesisir timur Bangka Tengah. Penelitian dilaksanakan pada bulan Agustus-September 2020 di kawasan hutan mangrove, Desa Belilik (Stasiun 1), Desa Kurau Barat (Stasiun 2) dan Desa Kurau Timur (Stasiun 3). Metode yang digunakan dalam peneltian ini adalah purposive sampling dan transek plot. Jenis kepiting bakau yang ditemukan teridentifikasi sebagai Scylla serrata, Scylla tranquebarica, Scylla olivacea dan Scylla paramamosain. Indeks keanekaragaman kepiting bakau pada kawasan tersebut tergolong rendah dengan nilai rata-rata sebesar 0,94, dan kelimpahan jenis kepiting bakau yang tertinggi adalah Scylla serrata yaitu sebesar 71 individu/m2. Tingkat kerapatan mangrove pada ketiga stasiun tergolong rendah dengan jenis vegetasi yang ditemukan adalah Rhizophora apiculata dan Sonneratia alba. Hasil principal component analysis menunjukkan bahwa keanekaragaman jenis kepiting bakau dipengaruhi oleh salinitas dan kecepatan arus air, sedangkan kelimpahan kepiting bakau dipengaruhi oleh kedalaman dan salinitas air.

Abstract

Penelitian ini bertujuan menganalisis pengaruh variasi temperatur deproteinasi pada daya adsorbsi kitosan udang krosok (Penaeus semisulcatus) terhadap logam besi (Fe) pada air kolong bekas penambangan timah timah di Pulau Bangka. Bahan baku kitosan yang digunakan dalam penelitian ini merupakan limbah cangkang udang krosok dari industri rumah tangga pembuatan ebi. Kitosan limbah cangkang udang ebi telah disintesis dalam tiga tahapan meliputi: deproteinasi, demineralisasi, dekolorisasi dan deasetilasi. Pada penelitian ini proses sintesis menggunakan variasi temperatur deproteinasi masing-masing: 30oC, 60oC, dan 90oC. Berdasarkan analisis data FTIR, dapat ditentukan nilai derajat deasetilasi sampel berturut-turut sebesar: 32,01% ; 30,94% dan 28,74%. Peningkatan temperatur deproteinasi menyebabkan nilai derajat deasetilasi kitosan menjadi menurun. Penurunan ini diakibatkan oleh rusaknya struktur kitin pada sampel akibat temperatur yang meningkat. Kandungan logam Fe pada air kulong yang digunakan dalam penelitian ini mencapai 6,1 ppm. Adsorbsi kitosan pada logam Fe dapat menurunkan kadar terlarut mencapai rata-rata 99,67% dari kadar awal. Kandungan gugus hidroksil pada kitosan menyebabkan terjadinya reaksi pembentukan senyawa hidroksida turunan dari logam besi terlarut. Senyawa besi hidroksida tersebut akan terpisah dari air dan membentuk endapan. Semakin besar nilai derajat deasetilasi maka akan semakin besar kandungan gugus hidroksil sehingga menyebabkan daya adsorbsi kitosan semakin meningkat.

Abstract

Bangka Island is the largest tin producer in Indonesia, dominated by onshore mining. Various ex-tin mining land reclamation programs have been implemented in Bangka and to monitor its success, indicators that characterize soil quality improvement are needed. One of the bioindicators that has potential as an indicator of the success of the reclamation program is the soil mesofauna community, such as Collembola (Springtail). Further research and variations in the correlation of data are needed to support this statement. This study calculates the abundance, diversity, species richness, evenness, and dominance of Collembola family associated with several soil fertility parameters. The research location is a pilot reclamation land of the alluvial inland tin mine “Air Kundur 3”. Seven families of Collembola were found with the abundance of 6,642 inviduals. The category of this land reclamation is low soil fertility. The results showed that an increase in the diversity, richness and evenness index values ​​was followed by an increase in the parameters C-Organic, Cation Exchange Capacity, thickness and dry weight of litter. The increase in the relative abundance and dominance of Collembola was followed by a decrease in the index of diversity, richness and evenness of species. This study confirm the prediction that the diversity, richness, and evenness index of Collembola species can be used as an indicator of soil fertility in post-tin mining reclamation.

Abstract

Garbage is a place for disease agents to develop, whether in the form of bacteria, mosquitoes, cockroaches and rats. These agents carry disease agents that can cause diarrhea, malaria, dengue fever, typhoid and others. The amount of waste in the environment is also related to the increasing population. The environment in the Bangka Belitung Islands Province is also inseparable from the problem of waste management. Especially at the service location, namely in Permis Village, Simpang Rimba District, South Bangka Regency. Permis village is a village with quite a large population in South Bangka district, so waste management and health education are very important. Pemis Village has a population of 3,894 people or a population density of 173.77 people/km2. Permis Village has geographical potential, namely the Permisan Hill and the beach. Permisan Hill or better known as the Mount Permisan Natural Tourism Park (TWA) in Simpang Rimba District, South Bangka Regency which is still natural and has not been managed properly. So it really needs to be managed, especially in an effort to make the area an ecotourism area that can grow people's economic resources. The service program that will be carried out is in the form of Independent Family-Based Waste Management activities within the Permis village population. The activity is in the form of Socialization of an independent family-based waste management system and Involving the Permis village community in the waste management application. The purpose of implementing this service is to build community commitment and awareness about the importance of good waste management towards a healthy and economically valuable family environment. So that it is hoped that an independent, healthy and competitive society will be formed.

Abstract

Tailing post-tin mining land has a sandy textured and loose structure. Those physical properties can affect the efficiency of fertilization and cause inefficiency of nutrient absorption in plants. That issue can be corrected by the application of organic material such as cow manure compost which has the potential for plant cultivation, especially for “porang” (Amorphaphillus oncophyllus Prain). This study aimed to examine the cultivation of porang plants in post-tin mining tailings by applying cow manure compost and to determine the best dose of cow manure compost for porang cultivation in artificial ex-tin mining land. This study used a single-group randomized design method with the treatment factor being the dose of cow manure compost consisting of five dose levels (5 t ha-1, 10 t ha-1, 15 t ha-1, 20 t ha-1, and 25 t ha-1). Each treatment level was replicated with five replications, and each replication consisted of five populations so the total population was 125 plants. The results showed that the application of various doses of cow manure compost to artificial post-tin mining land affected the growth and yield of porang plants. The treatment of cow manure compost at a dose of 25 t ha-1 gave the best growth and yield of porang plants. Heavy metal (Pb) analysis on porang tubers showed that all doses of cow manure compost had a Pb content value of <0.059%, which means that cow manure compost can reduce heavy metal uptake in porang tubers. Porang planted in artificial post-tin mining land is safe for consumption because lead (Pb) content was below the threshold of Indonesia National Standard (SNI) for food.
