Abstract

This study was aimed to determine the effect of relative growth rate and proximate levels of protein in tilapia fish exposed to heat stress and supplemented with the combination of willow leaf powder and chromium. A total of 30 tilapia fish with 1.3-1.5 cm long were divided into 6 treatment groups with 5 repetitions: fed with commercial feed at temperature 29±1° C (P1S1), fed with commercial feed combined with willow leaf at temperature 29±1° C (P2S1), fed with commercial feed combined with willow leaf and chromium at temperature 29±1° C (P3S1), fed with commercial feed at temperature 35±1° C (P1S2), fed with commercial feed combined with willow leaf at temperature 35±1° C (P2S2), fed with commercial feed combined with willow leaf and chromium at temperature 35±1° C (P3S2). The treatments were carried out for 15 days. Then, relative growth rate and proximate levels of proteins were calculated using Kjedahl methods. The results showed that there was an increase of the mean of relative growth rate and proximate levels of protein. Based on statistical test using factorial completely randomized design it was showed that there was a significant effect (P<0.01) on the interaction of feeding and temperature with the relative growth rate, but did not affect the relative growth rate of tilapia fish. The proximate level of tilapia fish protein was affected very significantly (P<0.01) by the food and the interaction between food and temperature as well, while the temperature treatment gave no significant effect on the proximate level of tilapia fish protein. In conclusion, the commercial feed combined with willow leaf and chromium can increase the relative growth rate and the proximate level of protein of tilapia fish exposed to heat stress.Key words: relative growth rate, proximate protein, willow leaf, chromium, tilapia fish

Abstract

This research is aiming to understand behind student motivation upon joining organization such as Jakampus UI that has a stereotype for its tendency towards violence. Within the scope of identity concept, people tends to join a group to be able to shows its identity as a person. This identity, then, become their basis for understanding their own perspective of their dignity and self-esteem. From that, this research also would like to find whether there is a connection between individual concept of self-esteem and the motivation upon joining Jakampus. This research would like to find how the student from University of Indonesia gave meaning and interpret about the supporter of Persija football club which has been attached with some kind of stereotype and the meaning of their membership inside that kind of community. The contagion theory is there to explain about the interpersonal communication process of the member of Jakampus as the effect of its self-esteem fulfilled or not. This research also use qualitative method, using the fenomenology approach. There are several findings that this research has found, which are (1) despite the rampant stereotyping from society towards supporter of Persija such as Jakampus, there is little to no effect of that stereotyping towards their motivation (2) the motivation for student to join Jakampus is to fulfill their self-esteem needs; and (3) the member of Jakampus are affected by the crowds when they are interacting within the organization. Penelitian ini bertujuan untuk memahami motivasi mahasiswa dalam bergabung dengan organisasi seperti Jakampus UI yang mana distereotipkan karena tendensinya terhadap tindakan kekerasan. Dalam konsep identitas, manusia bergabung dalam kelompok tertentu untuk bisa menunjukan identitas mereka. Identitas ini lah yang kemudian dijadikan sebagai dasar oleh dirinya sendiri dalam melihat harga diri mereka. Berangkat dari situ, penelitian ini berusaha untuk menemukan apakan ada keterkaitan antara konsep self-esteem seseorang dan motivasinya dalam bergabung dengan Jakampus. Artinya, penelitian ini bertujuan untuk bagaimana proses pemaknaan mahasiswa UI terkait dengan pendukung klub bola Persija yang memiliki stereotip tertentu dan makna dari keikutsertaan mereka dalam komunitas pendukung klub tersebut di kampus. Contagion Theory dipergunakan untuk menjelaskan mengenai komunikasi antar pribadi yang terjadi di antara anggota dari Jakampus sebagai dampak dari pemenuhan self-esteem itu terpenuhi atau tidak. Penelitian ini menggunakan metode kualitatif, dengan pendekatan secara fenomenologi. Ada beberapa temuan dari penelitian ini, yaitu (1) meskipun stereotip dari masyarakat terhadap pendukung Persija seperti Jakampus, sedikit bahkan tidak ada efek dari stereotyping tersebut terhadap motivasi mereka; (2) motivasi mahasiswa untuk ikut bergabung dengan Jakampus adalah untuk memenuhi kebutuhan self-esteem  mereka; dan (3) anggota Jakampus terdampak dari tindakan kerumunan dalam komunikasi antar pribadi mereka ketika sedang berada di dalam organisasi tersebut.

Abstract

Telah dilakukan pemodelan numerik menggunakan teknik beda hingga berdasarkan algoritma Gauss – Seidell. Penelitian ini bertujuan untuk menjelaskan proses transfer panas kasus steady state lapangan geotermal Jaboi, Sabang dengan menggunakan parameter fisis nilai konduktivitas termal material. Teknik ini berfungsi mendapatkan model sebaran suhu kemudian dibandingkan terhadap literatur. Teknik ini sesuai untuk struktur geologi kompleks seperti daerah penelitian. Pengujian sensitivitas sebelum memodelkan daerah geotermal Jaboi dilakukan untuk melihat efek geometri daerah geotermal dengan perubahan parameter masukan nilai konduktivitas dan syarat batas terhadap algoritma numerik yang dipakai. Dari hasil pengujian model sintetis sederhana diketahui bahwa litologi lapisan–lapisan batuan bawah permukaan mempengaruhi pola distribusi temperatur yang dihasilkan. Semakin tinggi konduktivitas termal batuan maka semakin tinggi distribusi temperatur yang akan dihasilkan. Berdasarkan hasil penelitian pola distribusi suhu model geologi daerah Jaboi, diperkirakan lapisan batuan berpotensi sebagai top reservoir berada di kedalaman >1000 m dengan perolehan temperatur sekitar 240oC di kedalaman 1050 m. Hasil perhitungan numerik memperkiraan temperatur maksimum di kedalaman 800 m dan kedalaman 900 m masing–masing sebesar 135oC dan 173oC, mengingat skala model bukan skala peta sebenarnya. Numerical modeling has been done using finite difference techniques based on the Gauss-Seidell algorithm. The purpose of this study was to explain the heat transfer process in the case of the steady state of Jaboi geothermal field, Sabang by using the physical parameters of the material's thermal conductivity value as input. This technique is to obtain a temperature distribution model, then compare it to the literature. This technique is suitable for complex geological structures such as the study area. Sensitivity testing before modeling the Jaboi geothermal area is done to see the geometrical effect of the geothermal area by changing input parameters of conductivity values and boundary conditions. The results of the simple synthetic model testing show that the lithology of the subsurface rock layers affects the temperature distribution pattern produced. The higher the thermal conductivity of the rock, the higher the temperature distribution will be produced. Based on the results of the study of the temperature distribution pattern of the Jaboi regional geological model, it is estimated that the rock layer has the potential as a top reservoir at a depth of> 1000 m, with a temperature of around 240oC at a depth of 1050 m. The results of numerical calculations estimate the maximum temperature at a depth of 800 m and a depth of 900 m with respectively 135oC and 173oC, considering the scale of the model is not the actual map scale.Keywords: geothermal, modeling, reservoir, caprock, boundary condition
