Abstract

Saat ini pemenuhan kebutuhan energi dalam negeri perlu diarahkan kepada diversifikasi sumber-sumber energi selain minyak bumi, salah satunya dengan program “waste to energy” dimana biogas adalah salah satu contohnya. Bahan yang bisa digunakan salah satunya adalah isi rumen sapi yang merupakan limbah Rumah Pemotongan Hewan (RPH) berupa rumput yang belum terfermentasi dan tercerna sepenuhnya oleh hewan. Di dalamnya terkandung bakteri metanogenik dan selulolitik sehingga bahan ini sangat efisien dalam membuat biogas. Penelitian ini bertujuan untuk mengetahui potensi penggunaan limbah isi rumen sapi sebagai bahan baku utama pembuatan biogas. jenis penelitian berupa pre experimental design. Jenis data yang digunakan adalah data primer yang diperoleh dari hasil pengukuran terhadap kuantitas biogas, temperatur dan kadar keasaman pada limbah isi rumen sapi. Berdasarkan data hasil penelitian, Rata-rata produksi biogas selama 21 hari sebanyak 21,57 ml dengan suhu rerata berkisar antara 29oC-30oC. Adapun kadar keasaman digester berada dalam kondisi normal. Limbah isi rumen sapi cukup potensial untuk dijadikan sebagai bahan baku utama produksi biogas.

Abstract

Makrozoobentos living relative lived, so it was better used as a guide environmental quality, as always contact with the waste into their habitat. Bivalvia and gastropod the most widely used as bioindicator pollution because he lived. This study aimed to know the level of species diversity in the estuary in estuary of Jeneberang River, to know the abundance of mollusks and know the type of mollusks that dominate in estuary of Jeneberang River. This research was descriptive of how diversity in estuary of Jeneberang River. The results obtained based on the diversity index showed <1.0, showed estuarine of Jeneberang River including heavy polluted waters. Based on the dominance index gained value approaching zero, then there is no dominant species.Key words: Makrozoobentos, Bivalvia, Gastropoda, Jeneberang River.

Abstract

Abstract. Ammonia in hospital wastewater comes from the process of reshuffling of amino acids by various types of aerobic and anaerobic bacteria (Aminullah et al, 2015). Large amounts of ammonia can be toxic and may interfere with aesthetics as they can produce a pungent odor and eutrophication in the surrounding area (Titiresmi and Sopiah, 2006). Therefore it takes innovation in lowering ammonia levels by using plants as biofilter. The purpose of this research is to see the effectiveness of Jirangau (Acorus calamus) and kangkung air (Ipomoea aquatica) plants in reducing ammonia (NH3) in RSUD wastewater from Bitung City. This research method is quasi-experiment with time series design. The main concern of this type of research is the effect of treatment. The results showed that the ammonia concentration at the beginning of the experiment was 3.18 mg / l. In Jirangau-covered containers, there was a decrease of ammonia content up to 0.025 mg / l (99.21%) on the 15th day and planted with water kangkung 0.042 mg / l (98.67%) on the 15th day. From these results, it is concluded that Jirangau plants are more effective than watercress plants in purifying ammonia levels in wastewater. It is therefore advisable to use aquatic plants in lowering the ammonia content in wastewater. Keywords: ammonia, jirangau, watercress.

Abstract

Abstract. This study aims to determine the effect of egg white at different concentrations on the content of water content and protein content in broiler chicken meatballs. This research uses Completely Randomized Rangcangan (CRD) with three replications and treatment four times, namely T0 = Control, T2 = 15 grams of Egg White, T2 = 30 grams of Egg White, T3 = 75 grams of White Egg. Variety analysis showed the addition of egg whites as pengeyal material at different concentrations significantly affected the content of water content and did not significantly affect the content of protein content. The average water content in the highest to lowest broiler chicken meatballs was obtained from P3 treatment of (61.48%), P0 (58.48%), P1 (53.58%), and P2 (43.32%). The average protein content in the lowest broiler chicken meatballs was obtained from treatment P0 (12.54%), P2 (13.29%), P1 (14.13%), and P3 (15.32%). From the results of research the content of water content and protein content with egg whites as different pengeyal ingredients is 43 grams of egg white. The best water content obtained in P2 treatment with an average value of 43.32%. The best protein content obtained in P3 treatment with an average value of 15.32%.Keywords: broiler, egg white, moisture content, protein content

Abstract

This study was an experimental study, aimed to determine the effect of cassava (Manihot esculenta Crantz) leaf extract on golden apple snail (Pomacea canaliculata L) mortality and to determine the leaf extract concentration that provide best effect on golden apple snail mortality. The variables of this study were cassava leaf extract as independent variable and golden apple snail mortality as dependent variable. This study used complete random design, consisted of 6 treatments: K0 (without cassava leaf extract application), K1 (50 g/L), K2 (75 g/L), K3 (100 g/L), K4 (125 g/L) and K5 (150 g/L), each treatment had three repetitions using 10 snails in every treatment, so the total number of snails used was 6 x 3 x 10 = 180. The test performed in two steps, pilot test and real test to observe the LC50 and LT50 value with observation parameters including rate and number of golden apple snail mortality for 48 hours observation. The obtained data were analyzed using variance analysis Fα = 0,05 and probit analysis, continued with BNT α = 0,05. It was observed that cassava leaf extract had significant effect on golden apple snail mortality and mortality rate began at 4 hour application. Result of BNT α = 0.05 providing the best effect was concentration of 100 g/L (K3). LT50 value for cassava leaf extract was at 57.280 hours, with regression slope  Y = -0,506 + 3,132X. Whereas the LC50 value was 88.716 g/L with regression slope Y = 7,997 – 1,762X. Keywords: golden apple snail (Pomacea canaliculata L)., Manihot esculenta Crantz and mortality

Abstract

This research was a descriptive study, which aims to determine the rate of growth of the fungus Rhizopus sp. the green bean tempe. This research was conducted by growing the fungus on PDA medium using fungus inoculum of 1 gram of green beans with tempeh making dilutions, starting from the dilutions 10-2 , 10-3 and 10-4 are plated on a petri dish of 0.1 mL and incubated for 24 hours. Variation of time of fermentation used without fermentation (0 h), 12 hours, 24 hours, 36 hours, 48 hours, 60 hours and 72 hours for each serial dilution. The number of fungi indirectly calculated using the count method bowls. The results of this study indicate that optimum growth is shown in 36 hours fermentation time with the number of colonies on the 10-2 dilution of 69 colonies (6.9 x 103 colonies / g) and 10-3 dilutions of the 27 colonies. While the 10-4 dilution only at the time of fermentation 36, 48 and 60 hours of growth of 2 colonies and each colony 1. The longer the fermentation time decreased the amount of mushrooms.

Abstract

The diversification limitation of exploiting tempe as an alternative nugget raw materials, substitution of meat and fish, and also to optimalize the very abundance resource, so it is necessary to do the right processing to the alternative food resource, which meant to give an additional point. Produce a liked product, also the adjustment of technology, and the cost that reached by the society. The aim of this reseach is to know the kind of glue material which can produce nugget tempe with the best chemical and organoleptic propertics. This research consit of 4 treatment; A1 (tempe nugget from bread powder), A2 (tempe nugget from tapioca), A3 (tempe nugget from sagu), A4 (tempe nugget maizena powder). Water convcentration analyse using oven method. Product was tested by organoleptic test (taste, smell, and tecsture). The result on water concentration analyse, that the smallest water concentration shown by A2  about 161,55% between from treatment A1 abaout 191,75%, A3 abaout 180,02% and A4 182, 45%. The result on organoleptic the teste of A1 product is the most like (75 %) between A2, A3 and A4 treatment. The smell of A2, A3 and A4 is the must like (67 %). And the best tecsture is all treatment.The result of this research is expected to give benefit in supporting the effort saking the alternative nugget glue material by using tempe which owning a high nutrition value. This research it is expected to find a kind if nugget tempe with the good glue, good taste and high nutrition value   Keywords: Glue material, organoleptic, tempe nugget
