This study aims to determine the factors that cause the high number of children dropping out of school in Yellu Village, South Misool District, Raja Ampat Islands.  This is a qualitative research with a social phenomelogy paradigm and was conducted in Yellu Village, South Misool District, Raja Ampat Islands. The number of children dropping out in Yellu Vilage was influenced by two factors. Internal factor includes lack of motivation from them in order to improve education. Some of external factors are lack of parental supporting, associating with their peers who are not in school, children who easily earn some money without going to school due to the emergence of pearl companies that requires labor and abundant marine resources to get fish and seaweed, unsupportive educational facilities, lack of supporting from local government and the private sector in order to education development.

This paper aims to find out about the commercialization of agricultural land, and the current model of agricultural land commercialization in West Koya and East Koya, and the Jayapura City's goverment attitude toward the lack of agricultural land in Jayapura City area. This is a qualitative research, using a social phenomenology paradigm. The results showed that the increasingly dense population of Jayapura City has led in the expansion of the city towards Koya region which is suburb area. Smooth transportation facilities and good infrastructure make Koya region more evolving. The land price in Koya area depends on the sale value of tax object, it is also influenced by the lack of land used as a place to live due to the density increasing of urban area so that the resident seek residential land in Koya area. Transmigrants or farmers who have no knowledge basis in agriculture, and have difficulty dealing with rice pests, causing them to be reluctant to plant rice, and difficult to adapt to the environmental situation. Farmers are more benefited by converting the farmland to fishery land. By utilizing former farmland to be used as a public fishing pond as amusement or tourism place. The economic pressure of community at the beginning of transmigration program was a heavy burden that felt by them, while the needs as supporting tools were hard to find. The high cost of living is the cause of transmigrants' inability to survive, therefore, they decided to leave their transmigration land by selling it to a second party.

One of the traditions that exist in the people of the West Misool islands is the Famari tradition. This tradition is usually carried out when someone from another village humiliates people from another village. This tradition is a tradition from generation to generation, but is only an oral story and has never been written into a written story. This study aims to determine the implementation model of the Famari tradition in communities in West Misool District, Raja Ampat Islands, and the methods used by indigenous peoples to maintain the Famari tradition in West Misool District, Raja Ampat Islands. This research is a qualitative descriptive study using a social phenomenological paradigm. Sources of data for analyzing research problems were obtained from two sources, namely: primary data and secondary data. The results show that the origin of the Famari tradition was created by the ancestors of the West Misool community in creating order, in which there are universal values such as the principle of mutual cooperation, human social function and property in society, consent as a general power, the principle of representation and deliberation. What causes the emergence of the Famari tradition is that in restoring moral balance, it creates collective awareness from community groups to neutralize differences. The Famari tradition does not see the time when it must be carried out, the form of fines in the Famari tradition is determined based on an agreement, the number of people who follow the tradition has no clear limit. Customary fines payment techniques in the Famari tradition are carried out after the party. Without an official invitation, residents came and got involved, to take part in Famari activities. The Famari tradition was created to avoid degrading other social groups, where there are sanctions as punishment for those who are guilty and restore moral balance in society.

Motor induksi telah dimanfaatkan industri sebagai sumber energi mekanik. Motor induksi sangat handal, murah, dan mudah dalam perawatannya. Motor induksi sulit dikendalikan karena salah satu kategori plant nonlinier. Salah satu cara yang digunakan untuk mengatur kecepatan motor induksi adalah mengatur vektornya. Agar motor induksi mudah untuk dikendalikan seperti motor dc penguat terpisah, maka motor induksi dimodelkan dalam referensi sumbu putar (model d-q). Penelitian ini menerapkan skema pengaturan kecepatan motor induksi menggunakan Switching Space Vector Pulse Width Modulation (SVPWM). Sistem ini menghasilkan error steady state rata-rata di bawah 4 (empat) rpm atau sebesar 0,3 % dengan diberi torsi beban antara 5 Nm sampai 35 Nm.
