Abstrak: Musim paceklik adalah bulan-bulan di mana kondisi cuaca sedang tidak baik untuk melaut sehingga produksi ikan rendah. Oleh karena itu, setiap rumah tangga nelayan harus pandai menerapkan strategi dalam mencari nafkah untuk memenuhi kebutuhan hidup mereka di musim paceklik. Strategi nafkah masyarakat nelayan terbagi menjadi dua, yaitu strategi nafkah ekonomi dan strategi sosial. Kedua bentuk strategi tersebut dihubungkan dengan kondisi sosial ekonomi rumah tangga nelayan menggunakan indikator kesejahteraan BKKBN (2018). Tujuan yang ingin dicapai dalam penelitian ini adalah menganalisis hubungan keragaman strategi nafkah dengan kondisi sosial ekonomi rumah tangga nelayan. Metode yang digunakan adalah metode kuantitatif yang dilakukan menggunakan kuesioner dan didukung dengan data kualitatif melalui wawancara mendalam serta observasi. Berdasarkan hasil penelitian yang telah diuji secara statistik dan didukung oleh data kualitatif menunjukkan bahwa terdapat hubungan yang signifikan antara variabel musim paceklik dengan variabel strategi nafkah yang dilakukan oleh rumah tangga nelayan dalam penelitian ini., The famine season is the month when the weather conditions are not good for fishing so that fish production is low. Therefore, every fishing household must be good at implementing strategies in making a living to meet their needs in the famine season. The livelihood strategies of fishing communities are divided into two, namely economic livelihood strategies and social strategies. Both forms of strategy are related to the socio-economic conditions of fishermen's households use the welfare indicators of BKKBN (2018). The aim of this research is to analyze the correlation of the diversity of livelihood strategies to the level of welfare of fishermen's households. The method used is a quantitative method using a questionnaire and supported by qualitative data through in-depth interviews and observation. Based on research that has been tested statistically and supported by qualitative data, it shows that there is a significant relationship between the famine season and the livelihood strategy carried out by fishing households in this research.

Judul: The Correlation with Livelihood Patterns of Fisher Households, The Correlation with Livelihood Patterns of Fisher Households
Abstrak: Masyarakat pesisir di Indonesia sebagian besar penduduknya mempunyai sumber penghasilan utama pada subsektor perikanan, salah satunya sebagai nelayan. Nelayan identik dengan pandangan bahwa kehidupan nelayan adalah sebagai rumah tangga miskin. Salah satu upaya mengatasi kemiskinan dalam rumah tangga nelayan adalah dengan menerapkan pola nafkah yang beragam. Modal terkuat yang rumah tangga nelayan andalkan dalam mengelola pola nafkah adalah dengan menerapkan modal sosial. Tujuan dari penelitian ini adalah menganalisis bagaimana hubungan modal sosial dengan pola nafkah yang diterapkan rumah tangga nelayan. Penelitian ini menggunakan pendekatan kuantitatif yang didukung dengan data kualitatif. Teknik pengumpulan data yang digunakan adalah teknik wawancara dengan menggunakan kuesioner untuk data kuantitatif dan wawancara mendalam untuk data kualitatif. Teknik pengambilan sample atau responden dalam penelitian ini yaitu Stratified random sampling. Hasil penelitian menunjukkan bahwa terdapat hubungan modal sosial dengan pola nafkah rumah tangga nelayan pada kategori kelompok nelayan kapal dan kelompok nelayan sampan yang digunakan rumah tangga nelayan. Dalam hal ini semakin tinggi modal sosial maka semakin beragam pula pola nafkah yang dilakukan rumah tangga nelayan., Most of the coastal communities in Indonesia have their main source of income in the fisheries subsector, one of which is as fishermen. Fishermen are synonymous with the view that fishermen live as poor households. One effort to overcome poverty in fishing households is to implement diverse living patterns. The strongest capital that fishing households rely on in managing their livelihood patterns is by applying social capital. The aim of this research is to analyze the correlation social capital with the livelihood patterns adopted by fishing households. This research uses a quantitative approach supported by qualitative data. The data collection technique used was an interview technique using a questionnaire for quantitative data and in-depth interviews for qualitative data. The sampling or respondent technique in this research is Stratified random sampling. The results of the research show that there is a correlation social capital with the livelihood patterns of fishing households in the categories of boat fishermen groups and canoe fishermen groups used by fishing households. In this case, the higher the social capital, the more diverse the livelihood patterns carried out by fishing househeholds.

Judul: Sintesis Paduan Ti-6Al-4Nb sebagai Matrial Implan Pengganti Komponen Tibial
Abstrak: Synthesis of Ti-6Al-4Nb alloy was done by melting using Tri Arc Melting Furnace. Each sample was remelted five times to ensure the homogenity. Aluminum and niobium addition were expected to stabilize α phase and β phase until the αβ-titanium alloy was resulted. Yet based on the experiment, it was α-titanium alloy resulted. α-titanium alloy was a Hexagonal Close Packed (HCP) crystalline structure which would be cracked if deformation non-uniaxial happens. The presence of oxygen in pure titanium significantly increased the hardness of titanium. The addition of aluminum was also able to increase the hardness of titanium alloy because aluminum more stabilize the α phase in the α-titanium alloy. The corrosion ressistance of titanium could be increased by adding aluminum and niobium. Titanium coating with HA/chitosan composite was also proved in decreasing the corrosion rate because it barried direct interaction between titanium alloy and corrotion solution.
