Judul: Strategy for Managing of Cilincing Fisheries Port North Jakarta
Abstrak: The Cakung Drain river ends at the water system of Cilincing Fisheries Port. As the river is highly polluted by domestics and industrial waste, it contributes significantly to the pollution of Cilincing fisheries port. The aim of this research is to estimate the pollution load and the assimilation capacity of the Cilincing Fisheries Port and to formulate a strategy for management of Cilincing Fisheries Port. Sample analysis and fied survey dery were conducted September 2005 uatil Mei 2006. SWOT analysis was used for formulating an effective strategy for management of the Cilincing Fisheries. Results from a research showed that the estimed pollution load from the river are as follow (each in ton/month) are BOD5 365,85, NO3 10,66, NH3 17,27, PO4 10,82, Pb 20,11 and COD 10.235. The assimilation capacities of each parameter observed for 500 m and 1.000 m from the coastal are as follow (each in ton/month) BOD5 (1.997,72 and 3.11,52), NO3 (-0.57 and -6,92), NH3 (22,65 and 19,94), PO4 (15,43 and 13,59), Pb (9,73 and 8,86), and COD (-22.150 and 434,31). Based on the result of SWOT analysis, the main strategies for management Cilincing Fisheries port, are namely : (1) To increase stakeholder attention relating to the management and utilization of marine resources that is supported by qualified human resources in order to get good sanitary; and (2) Rearrange of fisheries area and improve fisheries society by developing a comprehensive and integrated of Cakung Drain create high economy value.

Judul: Fishery Port Environmental Control Strategy (Case Study: of Cilacap Fishing Port Central Java)
Abstrak: Pelabuhan Perikanan Samudera Cilacap (PPSC) memiliki rata-rata produksi, jumlah kapal, dan unit penangkapan ikan yang meningkat selama periode 2017- 2021, sehingga membuat kegiatan perikanan di PPSC juga meningkat. Meningkatnya kegiatan perikanan dan minimnya kepedulian pengguna pelabuhan terhadap kebersihan lingkungan pelabuhan memberikan dampak negatif pada kondisi lingkungan pelabuhan, yaitu meningkatnya limbah padat dan cair di PPSC, sehingga PPSC membutuhkan alternatif strategi untuk mengatasi permasalahan lingkungan tersebut. Penelitian ini bertujuan untuk menilai penerapan pengendalian lingkungan, menganalisis persepsi pengguna pelabuhan, dan merumuskan strategi pengendalian lingkungan berbasis eco-fishingport di PPSC. Metode yang digunakan yaitu studi kasus dengan pengambilan data menggunakan wawancara dan observasi langsung. Metode analisis yang digunakan yaitu parameter eco-fishingport, skoring, skala likert, dan SWOT. Hasil penelitian menunjukkan penilaian penerapan pengendalian lingkungan dengan analisis indeks eco-fishingport mendapatkan skor 1,96, yaitu PPSC perlu peningkatan untuk menuju eco-fishingport. Persepsi pengguna pelabuhan terhadap pengendalian lingkungan masuk ke dalam kategori setuju dengan skor 224,94, yaitu pengguna pelabuhan setuju adanya penerapan pengendalian lingkungan yang telah diterapkan di PPSC. Hasil analisis matriks SWOT menunjukkan adanya delapan alternatif strategi pengendalian lingkungan, dengan strategi utama yaitu mengoptimalkan pelaksanaan dan fasilitas pengendalian lingkungan pelabuhan dan membuat kebijakan terkait menjaga kebersihan lingkungan pelabuhan dengan sanksi yang tegas apabila dilanggar., The Cilacap Fisheries Port (PPSC) has increased average production, number of vessels, and fishing units during the 2017-2021 period, thereby increasing fishing activities at PPSC. The increase in fishing activities and the lack of concern for port users for the cleanliness of the port environment has had a negative impact on port environmental conditions, namely increasing solid and liquid waste in PPSC, so PPSC needs alternative strategies to overcome these environmental problems. This study aims to assess the application of environmental control, analyze the perceptions of port users, and formulate strategy based on environmental control eco-fishingport at PPSC. The method used is a case study with data collection using interviews and observation. The analytical method used is parameters eco-fishingport, scoring, likert scale, and SWOT. The results of the study show the assessment of the application of environmental control by index analysis eco-fishingport get a score of 1,96, namely PPSC needs improvement towards an eco-fishingport. Port users' perceptions of environmental control fall into the agree category with a score of 224,94, namely port users agree with the implementation of environmental controls that have been implemented in PPSC. The results of the SWOT matrix analysis show that there are eight alternative environmental control strategies, with the main strategy of optimizing the implementation and facilities of port environmental control and making policies related to maintaining the cleanliness of the port environment with strict sanctions if violated.

Judul: Konstruksi aritmetika kurva eliptik F(2m) supersingular dan non-supersingular untuk skema kunci publik ElGamal
Abstrak: Algoritme ElGamal adalah salah satu algoritme kunci publik dengan aritmetik modular p yang mempunyai struktur grip siklik Z(p). Tingkat keanaman algoritme ini terletak pada pemecahan masalah logaritme diskret dari Z(p). Akan tetapi, tingkat keamanan tadi tahun ke tahun semakin menurun yang disebabkan kemampuan pemecahan algoritme diskret semakin meningkat. Untuk memenuhi tingkat keamanan yang memadai dibutuhkan p yang cukup besar yang menyebabkan proses enkripsi dan dekripsi menjadi lambat.
