KADAR LOGAM BERAT Pb (TIMBAL) SUSU KAMBING YANG DIBERI  PAKAN SILASE LIMBAH SAYURAN

Heavy metal is a very dangerous pollutant waste for it cannot be destroyed (non-degradable) and over time it will accumulate in the ocean. This study aims to determine the lead content in sediment, water and algal thallus as well as to determine the algae growth that has been treated with lead. The research method used was a completely randomized design (CRD) which consisted of 3 treatments, using different treatments for each sample. The highest metal content obtained in the sediment was 5,124 ppm, in the water was 0.120 ppm, and in the algae thallus was 4,816 ppm respectively. The results showed that Halimeda opuntia algae can grow even in an environment contaminated with lead heavy metal and can become a bioremediation agent by absorbing lead heavy metal. Keywords: Halimeda opuntia, Lead Heavy Metal, Algae Culture, Bioremediation Logam berat merupakan salah satu limbah pencemar yang sangat berbahaya karena tidak dapat dihancurkan (non degradable) dan dapat terakumulasi di perairan laut. Penelitian ini bertujuan untuk mengetahui kandungan timbal pada sedimen, air dan thallus alga yang dikultur serta mengetahui pertumbuhan alga yang telah diberi perlakuan timbal. Metode penelitian mengunakan metode Rancangan Acak Lengkap (RAL) yang terdiri dari 3 perlakuan, dengan menggunakan perlakuan yang berbeda pada tiap sampel dan kontrol.

Pencemaran air terhadap lingkungan dapat menyebabkan dampak membahayakan yang dapat dirasakan oleh makhluk hidup. Salah satu logam berat yang sering mencemari air adalah logam berat tembaga (Cu). Tujuan penelitian ini untuk mengetahui kemampuan daya serap rumput laut Gracilaria sp. terhadap logam berat Cu dan pertumbuhannya. Penelitian ini menggunakan metode eksperimental laboratoris dengan Rancangan Acak Lengkap (RAL) dengan menggunakan 4 perlakuan penambahan konsentrasi Cu, yaitu kontrol (0,54 ppm, sesuai dengan konsentrasi Cu pada air laut), 3 ppm, 6 ppm, 9 ppm dengan 3 kali pengulangan. Pengukuran kandungan logam Cu terhadap Gracilaria sp. dengan menggunakan Atomic Absorpsion Spektofotometri (AAS). Hasil penelitian menunjukkan bahwa penyerapan logam berat Cu tertinggi terdapat pada konsentrasi 9 ppm, yaitu sebesar 3,63 ppm dan terendah pada kontrol yaitu sebesar 0,27 ppm.. Pertumbuhan Gracilaria sp. tertinggi terdapat pada perlakuan kontrol dengan pertambahan berat sebesar 209,2 gram dan terendah pada konsentrasi 9 ppm, yaitu sebesar 162,9 gram. Semakin tinggi konsentrasi Cu yang diberikan maka semakin rendah pertumbuhan Gracilaria sp. Water pollution to the environment can cause dangerous impacts that can be felt by living things. One of the heavy metals that often pollutes water is the heavy metal copper (Cu). The purpose of this study was to determine the absorption capacity of Gracilaria sp. to the heavy metal Cu and its growth. This study used a laboratory experimental method with a completely randomized design (RAL) using 4 additional treatments of Cu concentration, namely control (0.54 ppm, according to the Cu concentration in seawater), 3 ppm, 6 ppm, 9 ppm with 3 repetitions. Measurement of Cu metal content against Gracilaria sp. by using Atomic Absorption Spectophotometry (AAS). The results showed that the highest absorption of heavy metal Cu was at a concentration of 9 ppm, which was 3.63 ppm and the lowest was 0,27 ppm in control.. The Growth of Gracilaria sp. The highest was found in the control treatment with a weight gain of 209.2 grams and the lowest was at a concentration of 9 ppm, which was 162.9 grams. The higher the concentration of Cu given, the lower the growth of Gracilaria sp.

Ultisol is the main type of land in Kalimantan, Sumatra, Papua and Sulawesi, with an area of almost 45.8 million ha or 25% of the land area of Indonesia. Ultisol has a relatively high acidity (average pH 4.5), high Al saturation, reaching 60%. The efforts to increase the fertility of ultisol soils such as the addition of organic materials such as Empty Oil Palm Bunches (OPEFB) and CFA (Coal Fly Ash) or Coal Fly Ash (CFA) improve the physical properties of Ultisol soil. Use of CFA that exceeds the limit can cause pollution especially copper (Cu) and lead (Pb). One way to recover soil from heavy metal contaminants with Phytoremediation technology, mustard (Brassica juncea L.) is one of the plants that easily absorb heavy metals so that it can be used as a Phytoremediation agent. The aims of this research to determine the use of CFA and OPEFB to fix up the ultisol soil and heavy metal content absorbed by plants. This study used Completely Randomized Design with 3 replications. The results showed that using of CFA and OPEFB can increase the available P so that it can increase the growth of mustard plants and absorption of heavy metals. By using the dozes of 54.54g CFA and 18.18g OPEFB (C3K1) can increase P- available at 181.67 m kg-1 . The uptake of heavy metals Cu and Pb in mustard plants is very high. The highest uptake in Cu reached 192.03 mg kg-1 , whereas in Pb it was 80 mg kg-1 . This number is still very high, so it is dangerous if consumed.

EFFECT OF UTILIZATION OF COMMERCIAL AND LOCAL CONCENTRATE DIETS ON FEED EFFICIENCY OF STARTER PIGS. The present study was conducted to determine the comparison of feed efficiency of starter pigs consumed local and commercial concentrate diets. Twenty castrated male pigs were allocated in individual crate. Experimental design used in the present study was completely randomized design (CRD) with four treatments and five replications. Treatments were arranged as follows: R1=Pokphan’s concentrate diet 32% + yellow corn 50% + rice bran 18%; R2= Benfeed’s concentrate diet 32% + yellow corn 50% + rice bran 18%; R3= Cargill’s concentrate diet 32% + yellow corn 50% + rice bran 18%; R4= Local’s concentrate diet 32% + yellow corn 50% + rice bran 18%. Variables measured were daily feed consumption, daily gain, and feed efficiency. Research results showed that treatments gave no significant effect on daily feed consumption, daily gain and feed efficiency. It can be concluded that starter pigs gave a similar respons when either local concentrate or commercial concentrate diets. Keywords: commercial concentrate, local concentrate, starter pig

Eichhornia crassipes is well-known as water hyacinth. Water hyacinth grows rapidly in the nutrient-rich water and high light intensity places. The uncontrollable growth of water hyacinth has caused many negative impacts to the environment. For instance, interrupted water transport and decreased population of aquatic lives. The capacity of utilising water hyacinth is slower than water hyacinth growth and water hyacinth is still considered as a threat to theecosystem. This work was focused on the study of the pharmacological activity and heavy metal content of water hyacinth in Lake Cipondoh, Tangerang. Fresh water hyacinth was pre-treated through oven-drying and milling process. After that, each part of the plant was macerated by using multiple extraction method with 96% ethanol/water and three variations of sample-to-solvent ratios (1:30, 1:50, and 1:75 w/v). The result of the experiment showed thatwater hyacinth leaves produced an extract with lowest IC 50 (55.76 ± 6.73 ppm) compared toother parts. The most optimum solvent used to achieve this result was 96% ethanol/water (1:1 v/v). In order to obtain the lowest antioxidant activity, the sample to solvent ratio used was 1:50 and the heavy metal in the extract was very low. With this result, it was concluded that there is a promising opportunity to apply the water hyacinth growing in Lake Cipondoh, Tangerang as herbal medicine ingredient. Through this utilization, the overall number of water hyacinth in Indonesia can be reduced or at the least be controlled, so that the environmental problem caused by this plant can be minimized.
