Abstract

The presence of tidal bore in the Kampar River (locally known as ‘bono’) may influence sedimentation in the Kampar River and its estuary. Understanding sedimentation mechanisms (e.g., erosion, deposition) is important to communities along the Kampar River, which can be studied by analyzing characteristics of grain size distribution. Here, we study riverbed sediment samples collected from 17 stations using an Ekman grab sampler, accompanied by bathymetry and acoustic Doppler current profiler (ADCP) measurements. Grain size data show that the sediments are coarser upstream and gradually finer downstream. Silty sands are predominant in the upstream section of the river, sands in its river body and sandy silts in the downstream. The results indicate the influence of undular bores on grain size characteristics. We also found that the propagation of bono and Kampar River’s funnelshaped morphology cause intense scouring events of riverbed sediments. Sortation values that range between 0.332.14 suggest unstable currents that result in randomly deposited sediments. The sediment mass transfer per area is positively towards downstream at the low tidal condition. However, after the passage of the bores, the sediment mass transfer area becomes negatively towards upstream.

Abstract

ABSTRACTPademawu Sub-District consist of salt ponds reached 740.96 Ha that is the second largest area in Pamekasan. Land-use overlapping problems between salt ponds and settlement influence the environmental degradation enhancement. The presence of salt ponds is indicated as the cause of increased salinity in well-water around the settlement so that the well-water is salty. To determine the influence of salt pond on groundwater pollution, the information regarding surface characteristics as well as the profile beneath the surface is essential. The method consisted of a hydro-geology survey, hydrochemistry, and geophysics (Geo-Electricity method). The type of groundwater is predominated by chloride (Na-Cl) and carbonate (Na-HCO3, Ca-HCO3). Based on groundwater chemistry element calculation, it is observed that there is an influence of salt pond infiltration on groundwater aquifer. The conductivity of groundwater ranged from 15,000–50,000 µS/cm (categorized into salty water). The specific resistance value of rocks beneath the surface varied between 0.1–300 that is usual in either coastal or alluvial area. The low value of specific resistance associated with alluvial lithology consisted of either brackish water or salt water expected the result of salt pond filtration. The depth of surface saltwater contaminating the aquifer layer ranged from 5 up to 30 meters. The presence of salt ponds influences the level of contamination of Cl- pollutant in shallow groundwater in Pademawu Sub-District, Madura, so it is necessary to re-arrange the land-use system in the coastal area.Keyword: groundwater pollution, salt pond, Pademawu Sub-District, Specific resistance Geo-ElectricityABSTRAK Kecamatan Pademawu terdiri atas kawasan tambak garam seluas 740,96 Ha yang merupakan wilayah terluas kedua di Pamekasan. Pemasalahan tumpang tindih jenis pemanfaatan lahan tambak garam dengan lahan pemukiman berpengaruh terhadap peningkatan degradasi lingkungan. Keberadaan tambak garam diindikasikan sebagai penyebab meningkatnya kadar salinitas pada air sumur di sekitar pemukiman sehingga air sumur terasa asin. Untuk mengetahui pengaruh keberadaan tambak garam terhadap pencemaran air tanah, dibutuhkan informasi mengenai karakteristik permukaan maupun profil bawah permukaan. Metode penelitian yang dipakai terdiri atas survei hidrogeologi, hidrokimia dan geofisika (metode geolistrik). Tipe air tanah didominasi oleh tipe klorida (Na-Cl) dan karbonat (Na-HCO3,Ca-HCO3), hasil perhitungan rasio unsur kimia air tanah menunjukkan adanya pengaruh infiltrasi air tambak garam kedalam akuifer air tanah. Nilai DHL air tanah daerah penelitian didominasi nilai dengan kisaran 15.000–50.000 µS/cm dan masuk dalam sifat air asin. Nilai tahanan jenis batuan bawah permukaan bervariasi antara 0,1–300 Ωm yang umum dimiliki pada kawasan pesisir atau alluvial. Nilai tahanan jenis rendah berasosiasi dengan litologi alluvial yang terdiri atas air payau atau air asin yang diduga hasil infiltrasi dari air tambak garam. Kedalaman muka air asin yang mencemari lapisan akuifer berada pada kisaran kedalaman 5 hingga 30 m. Keberadaan tambak garam memberi pengaruh terhadap tingkat pencemaran polutan Cl- pada air tanah dangkal yang ada di Kecamatan Pademawu, Madura, sehingga dibutuhkan penataan ulang sistem tata guna lahan di kawasan pesisir tersebut.Kata kunci: pencemaran air tanah, tambak garam, Kecamatan Pademawu, Geolistrik tahanan jenis

Abstract

[Land Suitability Modeling for Fishery Resource Enhancement in the Padang Pariaman Regency, West Sumatera, Indonesia: GIS and Multi-Criteria Evaluation Approaches] Land suitability analysis is required for successful aquaculture planning. Due to the geographical setting of the Padang Pariaman Regency, aquaculture development is likely hindered by the vulnerable coastal area. Suitability assessment of aquaculture projects is crucial to specify the best method espousing sustainable development in the study area. This study aims to select the most proper location to be developed as a center of shrimp aquaculture in the Padang Pariaman Regency. This study employed the multi-criteria decision-making (MCDM), and analytical hierarchy process (AHP) approaches. This study combined the GIS-based analysis, AHP, and MCDM to yield the most proper location for aquaculture development. The three sub-models (engineering, water quality, and infrastructure) are overlaid using the weighted linear combination (WLC) technique. The infrastructure sub-model resulted in the highest coverage of highly suitable criteria with 61.74%. By contrast, the highest percentage of the unsuitable category was found in the water quality sub-model with 17.67%. Of particular concern, 87.5 % of the study area is suitable for aquaculture development. The remaining region is categorized as highly suitable with 11.93%, found in the eastern Padang Pariaman. Thus, we conclude that developing shrimp aquaculture in the study area is possible. Still, the future environmental impacts should be considered beforehand.

Abstract

Daerah Teluk Bungus dan sekitarnya secara administratif termasuk dalam wilayah Kecamatan Bungus - Teluk Kabung terletak pada bagian Selatan Kota Padang – Sumatera Barat merupakan salah satu kawasan yang masuk dalam zona potensi terjadi gerakan tanah tinggi hingga menengah. Tulisan ini bertujuan untuk mengklasifikasikan tingkat kerentanan daerah rawan gerakan tanah daerah pesisir Teluk Bungus menggunakan metode Storie (Storie, 1978 ; Sitorus, 1995) berdasarkan karakteristik fisik berupa tataguna lahan, kelerengan, geologi dan curah hujan setempat. Klasifikasi tingkat kerentanan gerakan tanah menggunakan metode Storie di kawasan Bungus dan sekitarnya dan menghasilkan lima tingkat kerentanan gerakan tanah, yaitu sangat rendah, rendah, sedang, tinggi dan sangat tinggi. Secara umum klasifikasi tersebut menunjukkan bahwa sebagian besar lokasi longsor memang berada pada daerah dengan tingkat kerentanan gerakan tanah sedang hingga rendah. Kerentanan gerakan tanah di daerah penelitian dipengaruhi oleh kemiringan lereng dan litologi atau jenis tanah, serta curah hujan sebagai faktor pemicu terjadinya gerakan tanah.

Abstract. The Vulnerability of Underwater Cultural Heritages in Karang Bui Site, Northern Coast of West Java. Underwater remains which found in Karang Bui site, Karawang-Subang waters are originated from the colonial period of Vereenigde Oostindische Compagnie (VOC) and occupation period of the Kingdom of the Netherlands in Indonesia. Research on the vulnerability of the Karang Bui site has been conducted by the Ministry of Marine Affairs and Fisheries in 2017-2018. Research methods including observation of sea area; diving activities for site documentation, seabed profiles mapping, and the use of Side Scan Sonar. Besides looting activities that occurred in the past, the threats toward Karang Bui site preservation nowadays are from human and natural factors. Karang Bui site is located in shallow water with a depth of 5-12 m, so during the maximum elevation, the waves height and current velocity which forms at that location is increasing. Sedimentation level in Karang Bui site is also high caused by many rivers estuary around the site. The site is located within the area of P.T. Pertamina petroleum refineries which is likely the spill oil will threaten the archaeological remains. Furthermore, Karang Bui site is located near Patimban, Subang port development area which also the shipping line. Planning and protection measurement needs to be carried out immediately by related institutions and local governments. Thus, due those various vulnerability factors, the lifting of Karang Bui underwater artifacts is important to be done. Abstrak. Tinggalan bawah air yang ditemukan di Karang Bui, perairan Karawang-Subang, berasal dari masa Vereenigde Oostindische Compagnie (VOC) dan masa penjajahan Kerajaan Belanda di Indonesia. Penelitian terhadap kerentanan Situs Karang Bui telah dilakukan oleh Kementerian Kelautan dan Perikanan (KKP) pada tahun 2017-2018. Metode penelitian meliputi observasi kawasan laut, penyelaman bawah air untuk dokumentasi situs, pemetaan profil dasar laut, penggunaan side scan sonar. Selain aktivitas penjarahan pada masa lalu, ancaman terhadap kelestarian Situs Karang Bui saat ini berasal dari alam dan ulah manusia. Situs Karang Bui berada di perairan dangkal dengan kedalaman 5-12 m sehingga saat elevasi maksimal, tinggi gelombang dan kecepatan arus yang terbentuk di lokasi tersebut semakin meningkat. Tingkat sedimentasi di Situs Karang Bui juga tinggi karena banyak muara sungai di sekitar situs. Lokasi situs berada di area kilang-kilang pengeboran minyak bumi milik P.T. Pertamina, yang kemungkinan tumpahan minyak akan mengancam tinggalan arkeologis. Selain itu, lokasi situs berada di dekat area pembangunan pelabuhan Patimban, Subang, juga merupakan alur pelayaran. Perencanaan dan tindakan pelindungan Situs Karang Bui perlu segera dilakukan oleh institusi terkait dan pemerintah daerah. Oleh karena berbagai faktor kerentanan tersebut, pengangkatan artefak bawah air Karang Bui sangat penting untuk dilakukan.

Abstract

Program magang dan pelatihan oleh mahasiswa perguruan tinggi di suatu instansi bertujuan untuk pengembangan kapasitas dan kualitas pendidikan. Tingkat keberhasilan kegiatan magang dan pelatihan diukur berdasarkan evaluasi impresi mahasiswa terhadap instansi lokasi magang. Tujuan dari penelitian terhadap tingkat impresi mahasiswa terhadap program magang bidang riset kelautan dan perikanan di Kementerian Kelautan dan Perikanan (KKP) adalah untuk mengetahui keberhasilan program magang yang disediakan KKP terhadap peserta magang. Penentuan impresi tersebut menggunakan survei dengan pendekatan deskriptif kuantitatif. Responden terdiri dari peserta magang (mahasiswa) dan pengguna (pembimbing serta staf pelayanan teknis KKP). Tingkat kepuasan mahasiswa dinilai menggunakan empat dimensi aspek, meliputi aspek tangibles, reliability, assurance dan transparency, sedangkan tingkat kepuasan pengguna menggunakan tiga parameter penilaian yaitu kompetensi profesional, personal dan sosial. Seluruh parameter penentuan tingkat impresi berdasarkan pengisian beberapa pertanyaan melalui kanal googleform. Seluruh hasil pengisian diolah secara statistik dengan metode regresi linear. Tingkap impresi mahasiswa pada aspek tangibles, reliability dan assurance secara umum masuk kategori sangat puas dengan persentase 43,75%, 61,90% dan 53,57%. Pada aspek transparency, responden tertinggi 46,87% memilih kategori puas. Berdasarkan tingkat impresi pengguna magang terlihat bahwa kategori cukup puas mendominasi dari tiga kompetensi yang dinilaikan dengan persentase 60% (kompetensi profesional dan personal), dan 55% pada kompetensi sosial. Variabel kendala pelaksanaan program magang dan pelatihan (X2) dan solusi mengatasi kendala magang dan pelatihan (X3) memiliki peran penting dan berpengaruh secara signifikan terhadap kepuasan dan keberhasilan kegiatan magang mahasiswa di Loka Riset Sumberdaya dan Kerentanan Pesisir (LRSDKP). Workshop and internship programs performed by university students in an institution aim to develop their capacity and quality. The success standard for these programs can be evaluated from students’ impressions of the host institution. Research on the impression level of the internship students in the Ministry of Marine Affairs and Fisheries (MMAF) becomes an effective method to determine the triumph of the programs. A survey with a descriptive qualitative approach has been performed. The respondent comprises of internship participants and users. The student satisfaction level was examined based on tangibles, reliability, assurance, and transparency aspects and for determining user satisfaction, professional, personal, and social aspects were assessed. A Google form survey was used and the data was then analyzed statistically. Generally, students are very satisfied, with a percentage of 43.75%, 61.90%, and 53.57% for tangibles, reliability, and assurance parameters, respectively. Furthermore, for the transparency parameter, students are satisfied, with 46.87%. On the other hand, based on the users, they are sufficiently satisfied, with 60% for professional and personal competencies and 55% for social competency. The “obstacles” (X2) and “solution” (X3) variables played a significant role in the satisfaction of internship and workshop programs at the Coastal Resources and Vulnerability Research Center RICRV.

Abstract

Kabupaten Pangandaran merupakan wilayah pesisir dengan potensi wisata bahari yang tinggi, namun juga memiliki tingkat kerentanan yang signifikan terhadap bencana laut pesisir, seperti tsunami, abrasi, dan banjir rob. Untuk meningkatkan kesiapsiagaan masyarakat, pelatihan mitigasi bencana laut pesisir diselenggarakan dengan tujuan meningkatkan pemahaman serta keterampilan dalam menghadapi bencana. Penelitian ini bertujuan untuk mengevaluasi efektivitas pelatihan melalui metode kualitatif deskriptif dengan analisis pre-test dan post-test, serta kuesioner Rapid Self-Assessment (RSA). Pelatihan ini melibatkan 28 peserta dari berbagai kelompok masyarakat dan pemangku kepentingan serta berlangsung selama tiga hari dengan pendekatan interaktif yang mencakup pemaparan materi, simulasi, dan kunjungan lapangan. Hasil evaluasi menunjukkan peningkatan dalam pemahaman peserta, terbukti dari rata-rata skor pre-test sebesar 55,3 yang meningkat menjadi 82,7 pada post-test. Selain itu, hasil kuesioner RSA menunjukkan bahwa sebelum pelatihan, 49% peserta berada dalam kategori "mengetahui" dan 28% dalam kategori cukup tahu", sementara setelah pelatihan, 56% peserta masuk dalam kategori "mengetahui" dan 49% dalam kategori "sangat mengetahui". Data ini mendukung temuan bahwa pelatihan berbasis simulasi dan pendekatan lokal lebih efektif dibandingkan metode konvensional. Meski demikian, masih terdapat beberapa kendala, seperti keterbatasan anggaran dan belum adanya evaluasi jangka panjang. Peningkatan dukungan dari pemerintah dan pemangku kepentingan dalam mengoptimalkan program pelatihan serta pengembangan sistem monitoring dan evaluasi berkelanjutan. Dengan strategi yang lebih sistematis dan partisipatif, diharapkan masyarakat Pangandaran lebih tangguh dalam menghadapi bencana pesisir di masa depan.  Pangandaran Regency is a coastal area with significant marine tourism potential but also has a high level of vulnerability to coastal disasters such as tsunamis, coastal erosion, and tidal flooding. To enhance community preparedness, a coastal disaster mitigation training program was conducted to improve understanding and disaster response skills. This study aims to evaluate the effectiveness of the training using a qualitative descriptive method through pre-test and post-test analysis, as well as a Rapid Self-Assessment (RSA) questionnaire. The training involved 100 participants from various community groups and stakeholders and was conducted over three days with an interactive approach, including lectures, simulations, and field visits.The evaluation results showed an increase in participants’ understanding, as evidenced by the average pre-test score of 55.3, which increased to 82.7 in the post-test. Additionally, the RSA questionnaire results indicated that before the training, 49% of participants were in the "knowledgeable" category and 28% in the "moderately knowledgeable" category, while after the training, 56% of participants were in the "knowledgeable" category and 49% in the "highly knowledgeable" category. These data support the finding that simulation-based training and a localized approach are more effective than conventional methods. However, challenges remain, such as budget constraints and the absence of long-term evaluation. The support from the government and stakeholders is needed to optimize the training program and develop a sustainable monitoring and evaluation system. With a more systematic and participatory strategy, the Pangandaran community is expected to become more resilient in facing coastal disasters in the future.
