Abstract

Salah satu kelemahan pada proses pengolahan teh adalah tercampurnya tangkai dan daun teh sehingga proses grading dan sorting dilakukan pada produk akhir teh. Pada penelitian ini, dikembangkan suatu pendekatan baru pemisahan tangkai dan daun teh yaitu pada awal proses. Prinsip yang digunakan adalah dengan merontokan daun dari tangkai teh dan memisahkannya dengan berdasarkan perbedaan kecepatan terminal. Sebuah paket teknologi diperlukan untuk memisahkan tangkai dan daun teh sehingga keduanya dapat diproses secara terpisah untuk menghasilkan teh dengan kualitas terbaik (kelas satu) dalam pengolahan sistem teh ortodoks. Tujuan dari penelitian ini adalah untuk mengembangkan dan mengevaluasi paket teknologi pemisah daun dan tangkai teh yang telah dilayukan. Metode penelitian terdiri dari pembuatan desain mesin, pembuatan prototipe, uji fungsional mesin dan uji kinerja mesin. Paket teknologi yang telah dibangun terdiri dari tiga unit mesin yaitu mesin perontok, mesin pengayak getar dan mesin penghisap daun teh. Hasil pengujian kinerja terbaik diperoleh pada kecepatan putar silinder perontok 480 rpm yang menghasilkan persentase daun terhisap tertinggi (91,43%) dan persentase tangkai tidak terhisap paling tinggi (86,05%). Rata-rata kecepatan udara hisap pada permukaan tray saat pengujian berada pada kecepatan terminal daun teh, yaitu 1,78-2,98 m s-1 dan kapasitas rata-rata perontokan adalah 156,71 kg jam-1. Berdasarkan hasil penelitian, dapat dilihat bahwa pemisahan dengan metode perontok sangat cocok untuk proses pembuatan teh hijau karena dengan prinsip ini dapat meminimalisir kerusakan pada daun teh.

Abstract

Biodiesel is formed by transesterification reaction of vegetable or animal fatty acid with alcohol. Agitation of fluid in the biodiesel reactor is required for occurring of the transesterification reaction. This research aims to study the flow behaviour in reactor with different type of agitator using computational fluid dynamics simulation and determine the optimum type of agitator in biodiesel production. Flow behaviour which was studied includes temperature and fraction distribution, turbulence intensity, and vorticity of fluid. The study was conducted in transient and steady state simulation with agitation types of helical screw, turbine, propeller, and anchor. The material that was modelled consist of cooking oil and methanol with mole ratio of 1:6. The mixing process used 500 rpm agitation speed and 60-65 oC mixing temperature. Furthermore, to determine the optimum agitator, the analytical hierarchy process method was carried out. The simulation results were analysed then obtained the score of each agitator, which were 0.314 (anchor), 0.350 (helical screw), 0.249 (propeller) and 0.087 (turbine). Based on the result, the optimum agitator was the helical screw type.

Abstract

Abstrak. Limbah padat pada perkebunan kelapa sawit telah diketahui potensial sebagai bahan baku pupuk organik padat melalui proses pengomposan. Penelitian ini bertujuan mengembangkan teknik dan mengkarakterisasi proses pengomposan limbah daun kelapa sawit sebagai bahan dasar pupuk organik potensial. Proses pengomposan dilakukan dengan dua faktor perlakuan, meliputi komposisi bahan katalisator kompos (Bokashi, Vermikompos dan Natural) dan ukuran cacahan daun sawit (2 cm, 4 cm 6 cm). Parameter yang diamati meliputi persentase penyusutan massa dan fluktuasi perubahan suhu selama proses pengomposan, serta pengukuran zat hara Nitrogen, Phospor, Kalium (NPK) dan rasio C/N yang terkandung pada hasil pengomposan yang diukur setelah 10 dan 14 minggu proses pengomposan. Hasil penelitian menunjukkan bahwa metode pengomposan dengan bokashi memberikan penyusutan massa terbesar jika dibandingkan dua metode lainnya pada semua ukuran cacahan yaitu sebesar 32%. Cacahan daun sawit yang berukuran kecil cenderung memberikan proses pengomposan yang lebih cepat dan memberikan produk kompos yang lebih baik. Hasil pengukuran setelah proses pengomposan menunjukkan bahwa interaksi dua faktor perlakuan yang diberikan hanya berpengaruh signifikan pada rasio C/N dan tidak signifikan pada zat hara NPK. Utilization of Waste Palm Leaves as Raw Material Palm CompostAbstract. The use of oil palm plantation solid waste, particularly oil palm leaf as organic compost raw material are now receiving greater attention by researchers, but have not been fully utilized on large scale, either agriculturally or industrially. The aim of present study was to characterize composting process with oil palm leaf as raw material. The research of composting conducted with two combination of composting factor, namely: composting starter composition (i.e. Bokashi, vermi-compost and natural composting) and piece of frond dimension (2 cm, 4 cm, 6 cm). The percentage of mass reduction and temperature fluctuation during composting process were measured. The NPK compound and C/N ratio measurement were conducted after composting process which are 10 and 14 weeks. The result indicates that Bokashi starter composition gives higher percentage of mass reduction on all variant of piece of frond dimension. Results also showed that smaller piece of frond enable the composting process quicker and had better result. Statistical analysis reveals that combination of composting factors have significant effect on C/N ratio but insignificant on NPK.

Abstract

Catfish nurseries are required to be able to see the appropriate needs for catfish larvae, especially in pond water quality. However, in its application, generally adjustments to the needs of water quality are only carried out without any special treatment, so that the survival obtained is still low. The purpose of this research is to make a machine that can control the quality of catfish breeding water, test the performance of the machine and the effect of its use. This study used the method of formulating and evaluating the design and testing the performance of the machine which consisted of several stages, including: formulating and evaluating the design, manufacturing the machine, functional testing, performance testing, and the influence of the machine performance. The results obtained after testing were the performance of the machine affecting the speed of hatching eggs, the growth rate and survival of catfish larvae. The speed of hatching catfish eggs is 4 hours faster using a machine. The growth rate using a machine is 0.061g/head, while without using a machine it is 0.053g/head. The survival of fish larvae using machine was 80.3%, while without using machine was 63.1%. Keywords: Control, Fish Larvae, Growth Survival, Water Quality.

Abstract

Rajungan merupakan salah satu sumberdaya perikanan yang memiliki nilai ekonomi tinggi dalam perdagangan internasional. Rajungan (Portunus pelagicus) merupakan komoditas unggulan Kabupaten Karawang. Bubu lipat sangat populer digunakan oleh nelayan dan dioperasikan dengan sistem longline sehingga memerlukan alat bantu penarik untuk mempermudah dan mempercepat dalam operasi penangkapan. Informasi karakteristik teknis alat bantu penangkapannya masih sangat minim oleh karena itu perlu dilakukan kajian lebih lanjut. Penelitian ini bertujuan untuk menganalisa karakteristik teknis alat bantu penarik bubu rajungan terutama terkait desain, kebisingan dan konsumsi bahan bakar. Karakteristik teknis alat bantu penarik bubu rajungan dideskripsikan sesuai kondisi saat ini, sedangkan untuk kebisingan dan konsumsi bahan bakar dilakukan analisis deskripsi komparatif. Alat bantu penarik bubu pada nelayan pesisir Karawang terdapat perbedaan pada pereduksi putaran (gear box). Tenaga penggerak menggunakan mesin diesel dengan daya 8 – 12 PK, roda piringan penarik (line spool plate) terbuat dari bahan besi plat dan kayu serta karet ban bekas sebagai pelapis dengan diameter 17 – 50 cm. Gear box menggunakan gardan bekas dan roda gigi cacing (worm gear set). Kebisingan yang dihasilkan mesin penggerak pada area nelayan bekerja melebihi nilai ambang batas yang ditetapkan yaitu 91 dB dengan lama paparan lebih dari 2 jam. Dalam jangka panjang hal ini dapat menyebabkan gangguan pendengaran yaitu ketulian. Besaran nilai konsumsi bahan bakar mesin penggerak alat bantu dengan daya 8 dan 12 PK mesin penggerak pabrikan Jepang lebih unggul. Konsumsi bahan bakar pada kondisi putaran minimum dan maksimum untuk mesin berdaya 8 PK adalah 1,48 dan 5,93 liter, sedangkan mesin berdaya 12 PK adalah 2,35 dan 10,35 liter.Blue swimming crab (Portunus pelagicus) is a fishery resource that has the potential to utilize because it has high economic value in international trade. Portunus pelagicus is a leading export fisheries commodity in Karawang Regency; collapsible pots are very popular fishing gear fishermen use. The fishing is operated with a longline system that requires auxiliary hauling equipment to simplify and speed up the fishing operation. Information on auxiliary fishing equipment's technical characteristics is still minimal; therefore, further studies are needed. This study analyzes the pot hauler's technical characteristics, especially regarding design, noise, and fuel consumption. The technical characteristics of the pot hauler are described following the existing conditions, while a comparative descriptive analysis was carried out for noise and fuel consumption. There are differences in the gearbox for the fishing traps for fishermen in the coastal area of Karawang. The driving force uses a diesel engine with a power of 8-12 HP, the towing wheel (line spool plate) is made of iron plate and wood, and used rubber tires as a coating with a diameter of 17-50 cm. The gearbox uses a used axle and a worm gear set. The noise generated by the auxiliary equipment engines in the fishermen's working area exceeds the set noise limit value of 91 dB with an exposure period of more than 2 hours. In the long term, this could cause deafness to the fishermen. Theoretically, the fuel consumption value of the auxiliary equipment engines, with a power of 8 and 12 HP of the Japanese manufacturer, is superior. The fuel consumption at the minimum and maximum rotation conditions for the 8 HP engine is 1.48 and 5.93 liters, while the 12 HP engine is 2.35 and 10.35 liters, respectively.

The aim of this study was to evaluate the physiological responses and body weight loss of males local sheep to transportation with different positions on the vehicle. Ten males sheep with 16.112.27 kg of body weight and 8-10 months in aged were used in this study. Completely Randomized Design with two factors was used in this study. The first factor was positions on the vehicle (standing and lying down) and the second factors was sampling times (before and after transportation). All of sheep were transported in one Pick up (Mitsubishi L 300) for 8 hours with similar of density level of 0,27 m2/head. Data on body weight, rectal temperature, respiration rate, pulse, cortisol, glucose, creatinine, hemoglobin and hematocrit were collected before and after transportation. Results showed there was no significant interaction (P 0.05) between the position of the sheep in the vehicle with the time of sampling in all parameters (except pulse rate). Placing of sheep with standing and lying down position for 8 hours of transportation showed the same responses for body weight loss, rectal temperature, respiratory rate, cortisol level, glucose concentration, creatinine, hemoglobin and hematocrit. Based on those findings, it can be concluded that standing and lying position in the vehicle for 8 hours of transportation shows the similar effect on the physiological responses and body weight loss of local male sheeps.

Abstract

Transmitter and receiver were applied in this research to detect the mole plough. Transmitter was placed outside the farm while receiver was attached on the mole plough construction and then pulled by tractor. Mole plough was used to create drainage channel. However, creating drainage channel at slope of 0,02% is a difficult task as mole ploughing depth is strongly affected by the contour of soil surface. The objective of this research was to design a device which had ability to control mole ploughing depth. Transmitter used a modified green laser beam which used to measure the profile of soil surface. Receiver was used to receive signal. Light receiver sensor used photodiode which formed into matrix sized of (1x8), every row consisted of 40 sensor of photodiode with 8 levels of depth. When transmitter was activated, green laser beam transmitted 1.206 Hz frequency and can be transmitted for maximum 50 m. When photodiode sensor received green laser beam at allowable detection range, the light beam was transmitted to Arduino microcontroller. There were two microcontrollers used to control two units of relay. The first microcontroller was used to detect the contour level of soil surfaceand second microcontroller was used to measure the mole ploughing depth. The research found that there was deviation of mole ploughing depth between setpoint and field testing result.
