Dokumen ini menganalisis kesesuaian lahan tambak udang di dua kecamatan di Jawa Barat dengan mempertimbangkan parameter seperti penggunaan lahan, tekstur tanah, dan jarak dari sungai dan pantai. Evaluasi menunjukkan bahwa sebagian besar tambak saat ini berada di wilayah seharusnya menjadi sempadan sungai. Jika aturan dilaksanakan, luas lahan tambak yang sesuai akan berkurang 46,6% menjadi 12,7 ha.

EVALUASI KESESUAIAN LAHAN TAMBAK UDANG DI
KECAMATAN CIJULANG DAN PARIGI, CIAMIS, JAWA BARAT

20160043
Budidaya Perairan

Tuajuan dan Manfaat Penelitian
• untuk menganalisis dan mengevaluasi kesesuaian lahan tambak udang dengan
mempertimbangkan perencanaan wilayah sempadan pantai dan sempadan
sungai di Kecamatan Cijulang dan Parigi, Kabupaten Ciamis, Provinsi Jawa
Barat
• proses evaluasi akan menyeleksi suatu hal apakah sudah memenuhi
standar atau kompetensi dalam kegiatan budidaya udang vannamei yang
sesuai standar operasional Prosedur (SOP).

Metode Penelitian
• Metode yang digunakan untuk menghasilkan peta kesesuaian lahan tambak adalah analisis spasial
beberapa data parameter dengan mengggunakan SIG.
• Matriks kesesuaian lahan tambak udang terdiri dari 8 parameter seperti ditampilkan pada Tabel 1.
Secara matematis, proses penentuan
kesesuaian lahan tambak udang
menggunakan perhitungan berikut :
{([land use] x 20) + ([tekstur tanah] x
13) + ([jenis tanah] x 13) +
([kelerengan lahan] x 12) + ([jarak
dari garis pantai] x 12) + ([jarak dari
sungai] x 10) + ([pH] x 10) +
([salinitas] x 10)} x 1% ……….. (1)
S1 = sangat sesuai, dengan selang 3,27 – 3,78
S2 = sesuai, dengan selang 2,76 – 3,26
S3 = sesuai bersyarat, dengan selang 2,25 – 2,75
N = tidak sesuai, dengan selang 1,74 – 2,24

Hasil
• KONDISI UMUM TAMBAK
Tambak yang ada di sekitar muara sungai
Cijulang berada sangat dekat dengan muara
sungai yang memungkinkan terjadi abrasi.
• Analisis penutupan lahan
Lokasi yang sudah menjadi tambak udang ( )
di wilayah ini berdasarkan perhitungan adalah
sebesar 23,8 ha. kawasan tambak ( ) yang
luasnya sebesar 54 ha tambak itu sendiri dan
wilayah sekitar tambak yang biasanya banyak
ditumbuhi oleh semak belukar dan
pepohonan. Penggunaan lahan yang paling
luas adalah hutan mangrove ( ) dengan luas
sebesar 66,1 ha

Lahan yang baik untuk tambak, memiliki kelerengan sekitar 0
– 3%. Lahan tambak yang ada di sekitar muara sungai
Cijulang, memiliki kelerengan 0 – 3%. Oleh karena itu, tambak
yang sudah ada di wilayah tersebut dapat dikatakan sesuai dari
aspek

Sumber dan kualitas air
Parameter Nilai Standar Budidaya Nilai Uji
Derajat keasaman
(pH)
5,5 - 9,5. 6 - 8
Salinitas 15 - 30 ppt 3 – 24 ppt
Sumber air untuk mengisi tambak di sekitar muara sungai Cijulang
berasal dari sungai yang mengalir sepanjang tahun, yaitu sungai
Cijulang, sungai Cialit, dan sungai Citerusan.

Jarak dari sungai
Tambak tentunya memerlukan air dalam jumlah besar untuk media hidup udang yang akan
dibudidayakan. Dalam memudahkan dalam proses pengisian tambak maka tambak harus terletak dekat
dengan sumber air, baik air tawar maupun air asin.
Nilai Standar Nilai Uji
Jarak sungai 50 – 500 meter 0 – 50 meter
sehingga tambak tersebut termasuk wilayah yang tidak sesuai.
Jarak dari pantai
Nilai Standar Nilai Uji
Jarak dari Pantai 300 – 4000 meter 300 – 4000 meter
sehingga tambak tersebut termasuk wilayah yang sesuai.
Air laut diperlukan untuk mengatur salinitas air pada tambak.

Kesimpulan
Parameter yang digunakan dalam mengevaluasi kesesuaian
wilayah budidaya tambak udang di Kecamatan Cijulang dan
Parigi, Ciamis, yaitu: penggunaan lahan (land use); tekstur
tanah; jenis tanah; kelerengan; jarak dari pantai; jarak dari
sungai; pH perairan; dan salinitas;

Tambak yang eksis di wilayah ini hampir
seluruhnya berada pada wilayah yang
seharusnya menjadi sempadan sungai.
Apabila peraturan sempadan sungai dan
sempadan pantai dilaksanakan, maka luas
wilayah tambak udang yang sesuai akan
berkurang sebanyak 46,6% menjadi 12,7 ha;
yaitu 11,7 ha di wilayah sangat sesuai dan
1,0 ha di wilayah sesuai.

How Race, Age and Gender Shape Attitudes Towards Mental HealthThinkNow

��

Mental health has been in the news quite a bit lately. Dozens of U.S. states are currently suing Meta for contributing to the youth mental health crisis by inserting addictive features into their products, while the U.S. Surgeon General is touring the nation to bring awareness to the growing epidemic of loneliness and isolation. The country has endured periods of low national morale, such as in the 1970s when high inflation and the energy crisis worsened public sentiment following the Vietnam War. The current mood, however, feels different. Gallup recently reported that national mental health is at an all-time low, with few bright spots to lift spirits. To better understand how Americans are feeling and their attitudes towards mental health in general, ThinkNow conducted a nationally representative quantitative survey of 1,500 respondents and found some interesting differences among ethnic, age and gender groups. Technology For example, 52% agree that technology and social media have a negative impact on mental health, but when broken out by race, 61% of Whites felt technology had a negative effect, and only 48% of Hispanics thought it did. While technology has helped us keep in touch with friends and family in faraway places, it appears to have degraded our ability to connect in person. Staying connected online is a double-edged sword since the same news feed that brings us pictures of the grandkids and fluffy kittens also feeds us news about the wars in Israel and Ukraine, the dysfunction in Washington, the latest mass shooting and the climate crisis. Hispanics may have a built-in defense against the isolation technology breeds, owing to their large, multigenerational households, strong social support systems, and tendency to use social media to stay connected with relatives abroad. Age and Gender When asked how individuals rate their mental health, men rate it higher than women by 11 percentage points, and Baby Boomers rank it highest at 83%, saying it’s good or excellent vs. 57% of Gen Z saying the same. Gen Z spends the most amount of time on social media, so the notion that social media negatively affects mental health appears to be correlated. Unfortunately, Gen Z is also the generation that’s least comfortable discussing mental health concerns with healthcare professionals. Only 40% of them state they’re comfortable discussing their issues with a professional compared to 60% of Millennials and 65% of Boomers. Race Affects Attitudes As seen in previous research conducted by ThinkNow, Asian Americans lag other groups when it comes to awareness of mental health issues. Twenty-four percent of Asian Americans believe that having a mental health issue is a sign of weakness compared to the 16% average for all groups. Asians are also considerably less likely to be aware of mental health services in their communities (42% vs. 55%) and most likely to seek out information on social media (51% vs. 35%).

AI Trends in Creative Operations 2024 by Artwork Flow.pdfmarketingartwork

Creative operations teams expect increased AI use in 2024. Currently, over half of tasks are not AI-enabled, but this is expected to decrease in the coming year. ChatGPT is the most popular AI tool currently. Business leaders are more actively exploring AI benefits than individual contributors. Most respondents do not believe AI will impact workforce size in 2024. However, some inhibitions still exist around AI accuracy and lack of understanding. Creatives primarily want to use AI to save time on mundane tasks and boost productivity.

Google's Just Not That Into You: Understanding Core Updates & Search IntentLily Ray

��

1. Core updates from Google periodically change how its algorithms assess and rank websites and pages. This can impact rankings through shifts in user intent, site quality issues being caught up to, world events influencing queries, and overhauls to search like the E-A-T framework. 2. There are many possible user intents beyond just transactional, navigational and informational. Identifying intent shifts is important during core updates. Sites may need to optimize for new intents through different content types and sections. 3. Responding effectively to core updates requires analyzing "before and after" data to understand changes, identifying new intents or page types, and ensuring content matches appropriate intents across video, images, knowledge graphs and more.
