Abstract

Maturity of Mangrove Crab (Scylla sp)is a decisive factor in the life cycle of mangrove crab (Scylla sp). Human activities such as over-fishing of mangrove crab to meet market needs regardless the size is one of the causes of the reduced number of individuals in the wild. This study aims to determine the correlation between morphometric of maturity stage of mangrove crab (Scylla sp) in Kedungmutih Waters, Demak District. The study used exploratory descriptive method which site determination using purposive sampling methods. The research consisted of female mangrove crab sampling and field water quality measurement (DO, temperature, salinity, and pH), morphometric measurements and weighing body weight of female mangrove crab samples, and observation of maturity stage in the laboratory.Thematerial used in this study were female mud crab (Scylla sp) obtained from Kedungmutih Waters, Demak District. The results of this study showed that 94 female mangrove crabs crabs were found to have a carapace width ranging from 77.50 mm - 126.45 mm, for body weight ranging from 87 grams to 359.78 grams. While the fecundity stage were obtained from the stage of I - IV and on the size of 200 grams - 300 grams has an optimal fecundity stage on the stage II and III. There is correlation between morphometry and maturity stage of mangrove crab (Scyla sp) because when the weight of crabs increases, so does the addition of the number of eggs and also improvement of egg (gonads).  Kematangan telur pada Kepiting Bakau betina (Scylla sp) adalah faktor yang menentukan pada siklus hidup Kepiting Bakau (Scylla sp). Kegiatan manusia seperti penangkapan kepiting bakau yang tinggi untuk memenuhi kebutuhan pasar tanpa melihat ukuran yang ditangkap merupakan salah satu penyebab berkurangnya jumlah individu yang berada di alam. Penelitian ini bertujuan untuk mengetahui hubungan morfometrik terhadap tingkat kematangan tekur Kepiting Bakau Betina (Scylla sp) di kawasan perairan Kedungmutih,Kabupaten Demak. Metode penelitian yang digunakan adalah metode deskriptf eksploratif dengan penentuan lokasi menggunakan purposive sampling methods. Penelitian ini terdiri dari sampling kepiting bakau betina dan pengukuran kulaitas perairan di lapangan (DO, suhu , salinitas , dan pH), pengukuran morfometri dan penimbangan berat tubuh sampel kepiting bakau betina, dan pengamatan tingkat kematangan telur di laboratorium. Materi yang digunakan dalam penelitian ini adalah kepiting bakau betina (Scylla sp) yang diperoleh dari perairan Kedungmutih, Kadbupaten Demak. Hasil dari penelitian ini menunjukkan dari 94 ekor kepiting bakau betina yang didapatkan memiliki lebar karapas berkisar 77,50 mm – 126,45 mm, untuk berat tubuhnya berkisar 87 gram – 359,78 gram. Sedangkan pada tingkat kematangan telur didapatkan dari tingkat I – IV dan pada ukuran 200 gram – 300 gram memiliki tingkat kemmatangan telur yang optimal pada tingkat kematangan telur II dan III. Morfometri dan tingkat kematangan telur pada kepiting bakau betina (Scyla sp) memiliki hubungan dikarenakan jika pada bobot kepiting mengalami pembesaran maka pada telur mengalami penambahan jumlah dan mengalami peningkatan telur(gonad).

Abstract

The inventarization of coral bioecology is highly needed to identify the real condition of the observed coral, as a database in ecosystem management, as well as an attempt to rehabilitate critical coastal area. Coral condition valuation is conducted by counting the percentage of live coral coverage, by using the Line Intercept Transect method. This research shows that coral condition in Panjang Island falls into moderate category (with 29-49% of live coral coverage), which represent up to 57% from total observed area. Coral that falls under "bad" category (live coral coverage below 20%) is 29%, and only 7% of the observed area can be categorised as good (more than 50% coverage) and "very bad" (less than 5% of coverage). This condition is primarily caused by the decline of water ecology quality caused by sedimentation, west season wave activity, along with human activities like tourism, swimming, fishing, or shellfish gathering. These contributes many instances of coral-breaking caused by gleening.  Inventarisasi bio-ekogi terumbu karang sangatlah diperlukan guna mengetahui kondisi nyata terumbu karang yang dilakukan pemantauan, sebagai basis data dalam pengelolaan ekosistem serta upaya rehabilitasi kawasan kritis pesisi. Penilaian kondisi terumbu karang dilakukan dengan perhitungan persentase penutupan karang hidup menggunakan metode  LIT  (Line Intercept Transect). Hasil penelitian menunjukan bahwa Kondisi terumbu karang di Pulau Panjang termasuk dalam kategori sedang (dengan persen tutupan karang hidup 29 – 49 %)  mencapai 57 % dari keseluruhan area pengamatan. Selanjutnya kondisi terumbu karang dengan kategori buruk (persen tutupan karang hidup 20 %) mencapai 29 % dan hanya 7 % dalam kategori baik (50%) dan buruk sekali (persen tutupan karang hidup 5 %). Kondisi tutupan terumbu karang yang relative buruk diduga  diakibatkan oleh menurunnya kualitas ekologi perairan yang diakibatkan oleh  sedimentasi, aktivitas gelombang musim barat,serta aktivitas manusia seperti wisata, berenang, memancing ataupun pencari kerang turut serta memicu banyaknya pecahan karang akibat terinjak – injak (gleening).

Abstract

Tiger prawn ( Penaeus monodon Fabricius)  is one of very ideal species  of crustacean  to be cultivated. This is  due to  its growth is very quickly, highly survival rate, easy to live in compartement, and  its also very acceptable  by local and international market. In order to  increase production of cultivation, therefore caporit was applicated as disinfectant in cultivation  in order  to reduce  virus and bactery which  couse of  diseases. However to date, the impact of the use of kaporit has  not yet been known on  food attractant  degradation. The aim of  this research was  to know effect of the use of  caporit on food attractant  by the prawn. Research was conducted  in  Marine Station Teluk Awur, Jepara. Faculty of Fishery and Marine Science Diponegoro University.  The method of this research was ekperimental Laboratory  by using complete randomly  design  ( RAL) with four treatments and three replication , concentration kaporit 0 ppm  as control ( K1)  2 ppm ( K2), 4 ppm ( K3) and 6 ppm ( K4)., respectively. Data obtained was tested by F test ( Anova)The Results showed that food attractant  of  control treatment (K1)  is 53,68, K2 ( 2 ppm) is 285,25, K3 ( 4 ppm) is]364,59 and K4 ( 6 ppm) is]373,37 seconds. The  Results of statistical analysis confirmed  that the use of kaporit have an effect on food attractant   ( P < 0.05). However , continued test by BNT shows  that only  control gave  significant  different to the treatment, but  within threatment was not  give significant different . Udang windu (Penaeus monodon Fabricius) merupakan salah satu spesies crstacea yang ideal untuk dibudidayakan. Hal ini dikarenakan pertumbuhannya yang cepat, derajad kelulus hidupannya yang tinggi, tahan hidup dalam  tempat pemeliharaan, serta sangat digemari oleh konsumen dalam dan luar negeri. Guna peningkatan produksi dalam budidaya maka  digunakan kaporit sebagai disinfektan pada media air budidaya guna pengendalian bakteri dan virus sebagai penyebab munculnya penyakit. Namun sampai saat ini belum diketahui  dampak penggunaan kaporit terhadap penurunan daya aroma pakan yang diberikan. Tujuan dari penelitian ini adalah guna mengetahui pengaruh penggunaan kaporit terhadap daya tarik udang pada pakan yang diberikan. Penelitian dilaksanakan di Marine Station Teluk Awur,  Jepara.

Abstract

Concentration of Lead in the Seawater, Sediment, and the Seaweed Sargassum sp. in Jepara waters, Indonesia The increasing human activities led to an increase in waste disposal which eventually accumulates and decrease the water quality of rivers and seas. One of the pollutant resulted by human activities is heavy metal. The presence of heavy metals in the waters could directly harm the bioorganisms and indirectly affect human health by food chains. The purpose of this research is to investigate the lead content (Pb) in the water, sediment, and seaweed Sargassum sp., as well as to determine the status of pollution in Teluk Awur waters, Jepara. The research was conducted in November 2017 and January 2018 using descriptive method. Sampling sites were decided by Purposive Sampling Method. Analysis of lead content was conducted using AAS (Atomic Absorption Spectrophotometry). The results showed that the lead content of seawater in Teluk Awur, Jepara, was within 0.003 mg/L and not on the level of concern, according to KepMen LH No. 51/2004. The range of lead content in the sediment was 47- 68,35 mg/kg and considered as polluted, according to NRCC GBW07313. The range of lead content in the seaweed Sargassum sp. was 0.22-0.79 mg/kg and has exceeded the quality standard  specified by PerBPOM No. 23/2017. Meningkatnya  kegiatan  manusia  menyebabkan  peningkatan  pembuangan  limbah  yang pada akhirnya bermuara ke sungai maupun laut, yang mengakibatkan perairan laut menjadi tercemar. Salah satu pencemar akibat aktivitas   manusia   adalah   logam   berat   timbal yang dapat membahayakan kehidupan organisme perairan secara langsung, maupun tidak langsung terhadap kesehatan manusia. Tujuan penelitian ini adalah untuk mengetahui kandungan logam berat Pb pada air, sedimen, dan rumput laut Sargassum sp. serta untuk mengetahui status pencemaran di Perairan Teluk Awur, Jepara. Penelitian dilakukan pada bulan November 2017 dan Januari 2018. Metode penelitian yang digunakan  adalah  metode  deskriptif.  Penentuan  lokasi  penelitian  dilakukan dengan Purposive Sampling Method. Analisis logam berat Pb dilakukan dengan menggunakan AAS (Atomic Absorption Spectrophotometry). Hasil penelitian menunjukan kandungan logam berat Pb di Perairan Teluk Awur, Jepara, pada air laut yaitu 0,003 mg/L dan masih belum tercemar menurut KepMen LH No.51/2004. Kandungan logam berat Pb pada sedimen yaitu berkisar 47 - 68,35 mg/kg dan telah tercemar menurut NRCC GBW07313.

Abstract

 Empu Rancak coastal  waters in Karanggondang village, Mlonggo District is one of the coral reef ecosystem location in coastal area of  Jepara Regency. Following the growth of culinary and Marine  tourism bring the need for monitoring the condition of coral reefs so that such activity does not provide ecological impacts against the condition of coral reefs. The method used to assess the condition of coral reefs  is Line Intercept Transect which done by percentage calculation of living coral coverage. The research results shows that the condition of the coral reefs in a depth of 3 metres found coral cover percentage of 4.5%, while at a depth of 6 meters found coral cover percentage of 9.7%. From this result indicates the coral reefs in critical condition，however the high biodiversity and dominance index value is presumed that these coral reefs was in good condition. It`s showed by the high percentage of coral die either at a depth of 3 metres (95.54%) or at a depth of 6 meters(90.30%). The diversity of species of coral were found at a depth of 3 meters consist of 6 genus, they are: Goniastrea sp., Favia sp., Galaxea sp., Porites, Acropora sp. and Montipora sp., whereas at a depth of 6 meters were found more species of coral diversity for at least 11 genus, they are: Acropora sp., Favites sp., Echinopora sp., Goniastrea sp. Symphyllia agaricia sp, Favia sp., Goniopora sp., Porites sp., Montipora sp., Platygyra sp., and Montastrea sp. The condition of coral reefs cover which relatively critical are caused by decreasing the quality of waters ecology that caused by sedimentation rate and runoff processes of land activity, high waves in northwest monsoon and the growth of culinary tourism as well as marine  tourism in Empu Rancak coastal  waters gradually worsen the condition of coral reefs.  Perairan pantai Empu Rancak desa Karanggondang, Kecamatan Mlonggo merupakan salah satu lokasi ekosistem  terumbu karang yang berada pesisir di kabupaten Jepara. Dengan berkembangnya aktivitas wisata kuliner serta wisata  bahari, maka perlu dilakukan pemantauan kondisi terumbu karang agar kegiatan tersebut tidak tidak memberikan dampak ekologi terhadap kondisi terumbu karang. Metode yang dipergunakan untuk menilai kondisi terumbu karang adalah  dengan metode perhitungan persentase penutupan karang hidup menggunakan Line Intercept Transect. Hasil penelitian menunjukan bahwa Kondisi terumbu karang di kedalaman 3 meter ditemukan prosentasi tutupan karang sebesar 4,5 %, sedangkan pada kedalaman 6 meter ditemukan prosentase tutupan karang sebesar 9,7 %, maka kondisi terumbu karang di perairan pantai empu rancak Mlonggo, dalam kondisi buruk sekali, namun tingginya keanekaragaman dan nilai indeks dominasi, maka diduga bahwa terumbu karang dilokasi penelitian pernah dalam kondisi baik sebelumnya. Hal ini ditunjukan dengan tingginya prosentase karang mati baik pada kedalaman 3 meter (95,54 %) maupun pada kedalaman 6 meter (90,30 %). Keanekaragaman jenis karang yang ditemukan pada kedalaman 3 meter terdiri atas 6 genus yaitu : GoniastreaSp., Favia Sp., Galaxea Sp., Porites Sp., Acropora Sp.,dan Montipora Sp.,sedangkan pada kedalaman 6 meter ditemukan keanekaraamanan jenis karang yang lebih banyak (11 genus), yaitu : Acropora sp., Favites sp., Echinopora sp., Goniastrea sp., Symphyllia agaricia, Favia sp., Goniopora sp., Porites sp., Montipora sp., Platygyra sp. ,dan Montastrea sp. Kondisi tutupan terumbu karang yang relatif buruk sekali  diduga  diakibatkan oleh menurunnya kualitas ekologi perairan yang diakibatkan oleh oleh tekanan  laju  sedimentasi serta proses  run off dari aktivitas didaratan, tingginya paparan  gelombang pada saat musim barat serta  berkembangnya  wisata kuliner serta wisata bahari  di perairan Pantai Empu rancak yang  memperburuk kondisi terumbu karang.

Abstract

Online transportation has become a basic requirement of the general public in support of all activities to go to work, school or vacation to the sights. Public transportation services compete to provide the best service so that consumers feel comfortable using the services offered, so that all activities are noticed, one of them is the search for the shortest route in picking the buyer or delivering to the destination. Node Combination method can minimize memory usage and this methode is more optimal when compared to A* and Ant Colony in the shortest route search like Dijkstra algorithm, but can't store the history node that has been passed. Therefore, using node combination algorithm is very good in searching the shortest distance is not the shortest route. This paper is structured to modify the node combination algorithm to solve the problem of finding the shortest route at the dynamic location obtained from the transport fleet by displaying the nodes that have the shortest distance and will be implemented in the geographic information system in the form of map to facilitate the use of the system.

Abstract

In education quality assurance, the accuracy of test data is crucial. However, there is still a problem regarding to the possibility of incorrect data filled by test taker during paper-based test. On the contrary, this problem does not appear in computer-based test. In this study, a method was proposed in order to analyze the accuracy of answer sheet filling out in paper-based test using data mining technique. A single layer of data comprehension was added within the method instead of raw data. The results of the study were a web-based program for data pre-processing and decision tree models. There were 374 instances which were analyzed. The accuracy of answer sheet filling out attained 95.19% while the accuracy of classification varied from 99.47% to 100% depend on evaluation method chosen. This study could motivate the administrators for test improvement since it preferred computer-based test to paper-based.

Abstract

Penyu merupakan spesies yang terancam punah dan dilindungi dalam IUCN Red List of Threatened Species. Konservasi terhadap spesies ini telah dijalankan di berbagai tempat, termasuk di Kabupaten Kebumen, Jawa Tengah, Indonesia. Diketahui bahwa konservasi penyu di Kabupaten Kebumen mulai dikembangkan sejak tahun 2016. Konservasi tersebut dijalankan secara swadaya dan masih belum dilakukan secara resmi. Kegiatan konservasi ini memiliki potensi besar untuk dikembangkan secara maksimal menjadi kawasan konservasi berbasis ekowisata. Penelitian ini bertujuan untuk memetakan kawasan pesisir yang potensial untuk kegiatan konservasi menggunakan teknologi penginderaan jauh serta untuk mengetahui potensi ekowisata wilayah tersebut. Lokasi penelitian difokuskan di Pantai Kalibuntu dan Pantai Kembar Terpadu pada periode Maret sampai April 2021. Citra Sentinel-2A digunakan untuk pemetaan kawasan. Data terkait kelerengan, lebar, pasang surut, arus, dan batimetri pantai diambil secara primer dan sekunder. Sampel sedimen diklasifikasikan menurut skala wentworth dan dihitung persentase kelembabannya. Potensi ekowisata kawasan tersebut dinilai berdasarkan pengamatan langsung dan pengambilan data melalui wawancara. Hasil penelitian menunjukkan bahwa kedua pantai pengamatan memiliki tingkat kesesuaian sebesar 75,75% untuk dijadikan kawasan ekowisata. Analisis butir sedimen, perhitungan kelerengan pantai, dan lebar pantai menunjukkan bahwa kedua stasiun mendukung aktivitas peneluran penyu. Kedua stasiun memiliki kegiatan konservasi penyu seperti pemantauan peneluran, pemindahan telur ke sarang penetasan semi alami, penangkaran, pelepasliaran tukik, serta sosialisasi edukasi. Pengelolaan dilakukan oleh lembaga masyarakat lokal dan Kelompok Tani Ngadimulya. Dinas Kelautan dan Perikanan dan BKSDA Provinsi Jawa Tengah sudah memberikan bantuan sarana dan pelatihan. Budaya pesisir seperti batik penyu dan upacara Sedekah Laut menjadi potensi pendukung pengembangan ekowisata.Sea Turtles are protected species base on the IUCN Red List of Threatened Species. Conservation of this species has been done in various places, including in Kebumen Regency, Central Java, Indonesia since 2016. It is done independently and has not been officially. This activity has great potential to be maximally developed into an ecotourism-based conservation area. This study aims to map potential coastal areas for turtle conservation using remote sensing and to determine the ecotourism potential of the area. The research location is on Kalibuntu Beach and Kembar Terpadu Beach from March to April 2021. Sentinel-2A imagery is used for area mapping. Slope, width, tide, current, and beach bathymetry were taken primary and secondary. Sediment samples were classified according to the Wentworth scale and the moisture percentage was calculated. The ecotourism potential of the area was assessed based on direct observation and interviews. The results showed that the beaches had a suitability level of 75.75% to be used as an ecotourism area. Sediment analysis, coastal slope calculation, and beach width showed that both beaches supported turtle nesting activities. Both stations have turtle conservation activities such as eggs monitoring, transferring eggs to semi-natural hatchery nests, captive breeding, releasing hatchlings, and educational outreach.
