ABSTRAK: Romokalisari merupakan bagian hilir dari sungai Lamong, dimana daerah tersebut merupakan daerah pasang surut dan rawan terhadap banjir. Romokalisari banyak ditumbuhi oleh mangrove yang sangat rapat. Tujuan penelitian ini adalah untuk mengetahui pengaruh kerapatan mangrove terhadap laju pengendapan suspended sedimen pada perairan Romokalisari, Surabaya. Sampel sedimen diambil dari 8 stasiun yang terbagi dalam wilayah muara, mangrove dan laut, dimana masing-masing stasiun diulang 4 kali dengan periode setiap minggu. Analisis sampel sedimen menggunakan metode hydrometer dan analisis data menggunakan One Way Anova. Hasil penelitian menunjukkan bahwa ada perbedaan laju pengendapan suspended sedimen antara muara, mangrove dan laut, dengan nilai p = 0,046 < 0,05. Laju pengendapan suspended tertinggi terdapat pada stasiun 1 di wilayah muara dengan nilai sebesar 86,97 g/cm2/minggu dan laju pengendapan suspended terendah terdapat pada stasiun 2 di wilayah mangrove dengan nilai sebesar14,36g/cm2/minggu. ABSTRACT: Romokalisari is downstream part of the Lamong River, where the area is tidal and prone to flooding. Romokalisari is overgrown by very dense mangroves. The aim of this study was to determine the effect of mangrove density on suspended sediment rate in Romokalisari, Surabaya. Sediment sample were taken from 8 statios divided into estuaries, mangroves, and sea areas, each station was repeated 4 times with periods each week. Analysis of sediment samples using a hydrometer and data analysis using One Way Anova. The results showed that there were differences in suspended sedimentation rates between estuaries, mangroves and seas, with a value of p = 0,046 < 0,05. The highest suspended deposition rate is at station 1 in the estuary area with a value of 86.97 g/cm2/week and the lowest suspended deposition rate is at station 2 in the mangrove area with a value of 14.36 g/cm2/week.

These lectures outline the project of a general organology, which is to say an account of life when it is no longer just biological but technical, or when it involves not just organic matter but organized inorganic matter. This organology is also shown to require a modified Simondonian account of the shift from vital individuation to a three-stranded process of psychic, collective and technical individuation. Furthermore, such an approach involves extending the Derridean reading of Socrates's discussion of writing as a pharmakon, so that it becomes a more general account of the pharmacological character of retention and protention. By going back to Leroi-Gourhan, we can recognize that this also means pursuing the history of retentional modifications unfolding in the course of the history of what, with Lotka, can also be called exosomatization. It is thus a question of how exteriorization can, today, in an epoch when it becomes digital, and in an epoch that produces vast amounts of entropy at the thermodynamic, biological and noetic levels, still possibly produce new forms of interiorization, that is, new forms of thought, care and desire, amounting to so many chances to struggle against the planetary-scale pharmacological crisis with which we are currently afflicted.
