Abstract

ABSTRACTIndonesian National Standard (SNI) No. 8420 of 2018 concerning forest plant seeds is a reference for determining the quality of quality seeds. Technical instructions for assessing the quality of forest plant seeds by Regulation of the Director General of Land Rehabilitation and Social Forestry (RLPS) number P.05/V-SET/2009. Gmelina arborea and Aleurites moluccana seeds are priority seeds for production and use in RHL activities, so research focuses on these two types. The study aimed to determine the quality of Gmelina arborea and Aleurites moluccana seeds produced by the BPDAS-HL Bone Bolango Permanent Nursery. Data collection was carried out by selecting the sample using the Systematic Sampling with Random Start method based on SNI sampling requirements. There were 19,800 Gmelina arborea seeds and 5,900 Aleurites moluccana seeds with a sampling intensity of 0.2%. Testing for Gmelina arborea showed poor results in contrast to Aleurites moluccana in terms of percentage: Media compactness of the two types tested produced a percentage of 100% of the Aleurites moluccana type and 73.5% of the Gmelina arborea type. Seedling height, from the test percentages for both types, produces a percentage of 100%. For seed diameter, the Gmelina arborea test produced a value of 91%, and the Aleurites moluccana type produced a value of 100%. The percentage of leaves for the Gmelina arborea type is 45%, while the percentage for the Aleurites moluccana type is 100%. Average special requirements (RPK), the Gmelina arborea type produces a percentage of 77.37% while the Aleurites moluccana type produces a percentage of 100%. The test results (final score) resulted in 68 Gmelina arborea seedlings that fell into the first criterion (P), 120 in the second criterion (D) and 12 that did not pass the test (X). Meanwhile, the Aleurites moluccana type produces a percentage of 100% which is in the first quality (P).Keywords: Quality Testing; Seedlings; SNI; BPDASHL; Bone-Bolango.

Abstract

This study evaluates the environmental impact of road construction in the Muara Kaman Sedulang Nature Reserve (CAMKS), with a particular focus on land cover changes and biodiversity loss. The 8.189 km road construction aims to connect the isolated areas between Kupang Baru Village and Liang Buaya Village. Satellite imagery was used to analyze land cover changes due to road construction, while field surveys were conducted to assess the biodiversity of flora and fauna affected by the development. Findings research indicate that  majority of land covers consist of shrub/swamp thicket. Additionally, no protected plant species were found in either village, but naturally growing tree species were identified, and approximately 26% of protected wildlife were located within the CAMKS area. This means the impacts include habitat loss, disruption of natural behaviors, and increased risk of vehicle-related fatalities, and that the area holds high conservation value.

Abstract

Pantai  Kaisomaru  merupakan  objek  wisata  yang  baru  dibuka  di  Kecamatan Leato  Selatan. Pantai ini terkenal dengan pasir putihnya yang eksotik, selain pemandangannya yang sangat indah, bisa menarik wisatawan baik dari dalam maupun luar pulau. Pantai Kaisomaru juga merupakan tempat dengan perairan yang tenang dan bisa menikmati camping, snorkeling serta diving. Tujuan dari penelitian ini untuk mengetahui potensi Ekowisata Pantai Kaisomaru dan tingkat kelayakan potensi pengembangan ekowisata di Pantai Kaisomaru. Metode yang digunakan dalam penelitian ini yaitu metode deskriptif kualitatif dengan menggunakan teknik pengamatan secara langsung (survey).  Teknik analisis yang digunakan terdiri dari dua analisis yaitu panduan analisis daerah operasi objek dan daya tarik wisata alam (ADO-ODTWA) serta analisis kelayakan potensi objek wisata dengan berdasarkan metode penilaian kelayakan potensi objek wisata menurut Pedoman Analisis Daerah Operasi Objek dan Daya Tarik Wisata Alam (ADO-ODTWA) oleh Dirjen PHKA Tahun 2003. Hasil penelitian ini menunjukkan Pantai Kaisomaru memiliki nilai tingkat kelayakan yang berkisar antara 71% - 94% dan termasuk dalam interpretasi kelayakan dengan kategori tinggi pada lima kriteria yaitu 1) Aksesibilitas, 2) Kondisi Lingkungan Sosial Ekonomi, 3) Pengelolaan dan Pelayanan, 4) Sarana dan Prasarana, 5) Ketersediaan Air Bersih. Sedangkan, dua kriteria yang memiliki nilai dengan interpretasi kelayakan Sedang, yaitu 1) Daya Tarik, 2) Akomodasi. Hasil penilaian ODTWA keseluruhan pada kawasan wisata Pantai Kaisomaru memiliki nilai tertinggi yaitu 3.730 dengan indeks kelayakan 79,5% menunjukan klasifikasi tinggi yang berarti objek wisata Pantai Kaisomaru menunjukan layak untuk dikembangkan. Namun, beberapa aspek seperti peningkatan akomodasi serta tambahan sarana dan prasana dapat menjadi fokus dalam upaya pengembangan keberlanjutan wisata.

Abstract

Propolis is a resinous material that bees gather from specific plant exudate streams and utilize to build hives, caulk or seal crevices, create funnels for bees to enter, store honey and pollen, maintain a warm environment, and function as a natural antibacterial. One type of propolis from the Meliponini Tribe, Propolis Homotrigona Apicalis, is made from resin of the damar tree. This research aims to present scientific data on the effects of propolis as an antibacterial in the human gastrointestinal system. The parameters examined included qualitative phytochemical activity, Porphyromonas sp, Steptococcus sp, and Eschericia sp activity as measured by the minimum inhibitory concentration (MIC) using the agar well method on Mueller Hiton Agar (MHA) media, as well as testing for antibacterial potency and comparing its activity to that of a positive chloramphenicol control. Using the cold maceration technique, 96% EtOH solvent was used to extract propolis over the course of three 24-hour periods. Alkaloids, flavonoids, triterpenoids, and carbohydrates were all active, according to the findings of phytochemical tests. According to the findings of the activity test, Porphyromonas sp, Steptococcus sp, and Eschericia sp all exhibited antibacterial activity. Propolis Homotrigona Apicalis has the potential to be utilized as a treatment that treats diarhea, gum inflammation, and bad breath since it has antibacterial action in these areas as well as a healthy digestive system.

Abstract

Pohon adalah salah satu elemen penting pada lanskap kampus karena memiliki banyak fungsi, misalnya sebagai peneduh, penyerapan karbon, dan suplai oksigen. Sehingga, perawatan pohon menjadi hal yang harus dilakukan untuk mendukung keberlangsungan hidup dan fungsi pohon. Penelitian ini bertujuan untuk mengevaluasi tingkat kerusakan pohon pada lanskap kampus UKSW Diponegoro. Metode yang digunakan dalam penelitian ini adalah purposive sampling, dimana pohon yang dijadikan sampel adalah pohon yang memiliki diameter minimal 20 cm. Teknik analisis data yang digunakan adalah Forest Health Monitoring (FHM). Teknik ini berfokus pada bagian fisik pohon, dimana indikator adalah bagian kerusakan, tipe kerusakan, dan jumlah keparahan. Hasil Penelitian menunjukkan bahwa terdapat 433 sampel pohon yang memenuhi kriteria minimal diameter 20 cm. Jenis pohon yang mendominasi lanskap kampus UKSW antara lain pohon Kiara  Payung (Filicium decipiens) dengan jumlah 55, Glodokan tiang (Polyalthia longifolia) dengan jumlah 35 dan Angsana (Pterocarpus indicus) dengan jumlah 57 pada kampus UKSW Diponegoro. Dari hasil analisis FHM ditemukan bahwa pohon yang mengalami rusak ringan sebesar 19 pohon, rusak sedang 410 pohon dan rusak berat 4 pohon. Kemudian, jenis kerusakan yang mendominasi pada seluruh pohon adalah patahnya cabang atau kematian, rusaknya daun serta perubahan warna daun. Kesimpulan dari penelitian ini adalah sebagian besar pohon di UKSW masuk dalam kategori rusak sedang dan kerusakan yang dialami oleh pohon tersebut meliputi patahnya cabang atau kematian, kerusakan pada daun, serta perubahan warna daun.
