Judul: Involution of agrarian movement and the fate of peasants: a study of peasant movement dynamics in Lampung Province
Abstrak: One of the elements of Lampung community which suffer political, economic and cultural injustice is peasant. In the New Order era, peasant were not able to fight for a fair and equal right and need of agrarian (land) resource due to state oppression. At the era of democratization, the structure of political opportunity is widely opened and peasants have their chance to continue their assertion. In the early reformation era, collective actions have been organized up to provincial level. Up to this moment their condition tend to weaken. The researh question was: “How peasant movement which occur and grow during the already opened democratic era cannot strengthen itself and make substantial change for peasants’ life ?” The purpose of this research was: (1) to clarify the conditions of agrarian relations which become the main trigger of peasant movement; (2) to explain interrelationship between the elements that support the collective actions of peasant movement; (3) and to explain the course of the peasant movement development (which is represented by peasant movement organizations) in making structural agrarian changes in democratic era. This research was intentionally conducted in Lampung Province due to some criteria, made use of constructivism paradigm, with a case study design on the provincial level peasant movement organization (Dewan Tani Lampung, Ikatan Petani Lampung, Serikat Petani Lampung and Mirak Nadai). As the consequence, used qualitative method. Data was obtained through in-depth interviews, documentations, observations and secondary data. The data source was NGO, peasant movement activists, enterprises, government agencies, researh agencies, and peasants. Data were processed and analyzed using qualitative methode. The results of this research indicate, first, strained agrarian structural situation was the main precondition of the emergence of peasant movement. This condition was triggered by development policy that was not responsive to peasant interests. Second, no matter how exclusive the political opportunity was, there were always spaces for peasants to struggle. Third, integrative resource structure of peasants and non-peasants was the main characteristic of provincial scale peasant movement. Fourth, the strengthening speed of resource mobilization structure of the peasant movement and positive response of peasants to political opportunity (national political structure deconstruction as a momentum) were due to potential availability of resource mobilization which grown within sub-cultural peasant opposition. Fifth, the stagnation of peasant movement occured because the strengthening process of resource mobilization structure was depraved by behavioural disorientation of elite actors which cause unpredictable and uncontrolable consequences. Sixth, the agrarian movement involution toak place when resource mobilization structure weaken (deformed, decoupled, and stagnant) and structural properties of movement organization adhered to proper agrarian system, while the movement program has not been institutionalized by it self.

Judul: The Effect of Interaction between Peasant Movement and Government Reformist Actor Initiative on the Struggle of Agrarian Reform
Abstrak: Ketimpangan penguasaan tanah telah memicu gerakan petani untuk memperjuangkan pelaksanaan reforma agraria. Perjuangan gerakan petani dari bawah ini dapat diperkuat dengan adanya inisiatif dari atas oleh aktor reformis pemerintah. Penelitian ini menggunakan pendekatan kuantitatif dan kualitatif untuk melihat pengaruh antara gerakan petani terhadap zona interaksi dan trajektori perjuangan reforma agraria dan antara zona interaksi terhadap trajektori perjuangan reforma agraria. Pengaruh antar variabel ini secara statistik diuji menggunakan aplikasi SmartPLS 3.0 dengan uji path coefficient, uji t-statistic, dan uji p-value pada 30 petani AMANAT sebagai respondens. Hasil penelitian yang diperoleh menunjukkan bahwa gerakan petani memiliki pengaruh positif dan signifikan terhadap zona interaksi dan trajektori perjuangan reforma agraria. Zona interaksi memiliki pengaruh positif namun tidak signifikan terhadap trajektori perjuangan reforma agraria., Inequality in land tenure has triggered the peasant movement to strive for agrarian reform implementation. The peasant movement from below may be strengthened by the initiative from above by government reformist actors. This research uses quantitative and qualitative approaches to understand the influence of peasant movement to interaction zone and the trajectory of agrarian reform struggle and subsequently the influence of interaction zone to the trajectory of agrarian reform struggle. The influence between variables is statistically tested using the SmartPLS 3.0 application with the path coefficient test, t-statistic test, and p-value test on 30 AMANAT farmers. The results obtained indicate that the peasant movement has a positive and significant influence on the interaction zone and trajectory of agrarian reform struggle. The interaction zone has a positive but insignificant influence on the trajectory of the agrarian reform struggle.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
