PENGARUH HAMBATAN SAMPING TERHADAP KINERJA JALAN (STUDI KASUS: JL. LEMBONG, KOTA MANADO)

Jalan menjadi prasarana transportasi darat yang sangat penting dalam menunjang aktivitas masyarakat, sehingga dapat memberikan akses yang mudah bagi masyarakat baik mobilitas maupun ke tata guna lahan. Pertambahan penduduk mengakibatkan adanya peningkatan terhadap penggunaan transportasi darat, sehingga kapasitas dan kinerja jalan pada jalan berkurang. Pada kondisi ini kemacetan pun terjadi, salah satu faktor penyebabnya adalah aktivitas pada sisi jalan atau hambatan samping Analisa pengaruh hambatan samping terhadap kinerja jalan perlu dilakukan untuk mengatasi permasalahan lalu lintas. Dalam menganalisa data ini terbagi menjadi dua bagian yaitu volume, kecepatan dan kecepatan arus bebas menggunakan Manual Kapasitas Jalan Indonesia (MKJI) 1997. Sedangkan analisis kapasitas untuk derajat kejenuhan diperoleh melalui model linear Greenshield, model logaritmik Greenberg, dan exponential Underwood sebagai tinjauan tingkat pelayanan jalan. Pengaruh hambatan samping dianalisis menggunakan regresi liniear berganda serta tundaan dengan bantuan Microsoft Excel. Kemudian analisis melalui simulasi dari software Simulation Of Urban Mobility (SUMO).Model terpilih untuk mendapatkan nilai kapasitas model liniear Greenshield dilihat dari nilai koefisien determinasi (R2) tertinggi yaitu pada hari Kamis, 5 November 2020 sebesar 0,7701 sehingga didapat nilai kapasitas sebesar 426,624 smp/jam dan volume pada jam puncak sebesar 494,4 smp/jam sehingga nilai derajat kejenuhan sebesar 1,159 dengan tingkat pelayanan jalan LOS F, dan tundaan sebesar 58,951 detik. Hambatan samping mempengaruhi kinerja jalan sebesar 74,8967% terhadap kecepatan. Kemudian, analisis dengan simulasi melalui software SUMO dilakukan pelebaran jalan menjadi 3 lajur sehingga saat hambatan samping rendah nilai kecepatan sebesar 13,414 km/jam dan hambatan samping tinggi nilai kecepatan sebesar 8,42 km/jam..Kata kunci: Hambatan Samping, Kinerja Jalan, Greenshield, Greenberg, Underwood, Level Of Service (LOS), Simulation Of Urban Mobility (SUMO

POTENTIAL BIRD REPELLENTS TO REDUCE BIRD DAMAGE TO LETTUCE SEED AND SEEDLINGS

The authors evaluated the effectiveness of ReJeX-iT® AG-145, Mesurol®, activated charcoal, lime, and fipronil to reduce homed lark damage to lettuce seeds and seedlings. In Experiment 1, homed larks consumed significantly more feed mixture (50:50 grains and lettuce seed) than untreated clay-coated lettuce seed in a three-day choice-test. In Experiment 2, where clay-coated lettuce seed was treated with ReJeX-iT® AG- 145, Mesurol®, activated charcoal, or lime, there was no significant difference in consumption of untreated clay-coated lettuce seed and treated clay-coated lettuce seed. Homed larks consumed insignificant amounts of all seed treatments including untreated coated lettuce seed. In this experiment homed larks lost an average of 28 % of their body weight over the three-day test period. It was concluded that the clay seed coating alone reduced damage significantly. In the aviary test, flats of sprouting lettuce seedlings were sprayed with Mesurol® (4 kg/ha), ReJeX-iT® AG-145 (64 kg/ha), lime (32 kg/ha), activated charcoal (32 kg/ha), and fipronil(4 kg/ha). Mesurol®, ReJeX-iT® AG-145, and lime significantly reduced consumption of lettuce seedlings over a four-day test period. Even though lime significantly reduced consumption, homed larks still consumed over 50% of the available lettuce seedlings. Field evaluations are warranted with Mesurol® and ReJeX-iT® AG-145

HTLV-III Serology in Hemophilia: Relationship with Immunologic Abnormalities

We investigated the relationship of the presence of antibodies to HTLV-III and immunologic abnormalities in patients with hemophilia. Serum antibodies to HTLV-III were analyzed by ELISA assay, immunoprecipitation of labeled cell extracts, and immunoprecipitation of purified HTLV-III p24. Thirty-four (61%) of the total group (n = 56) had antibody to HTLV-III; 34 (76%) of 45 patients given commercial factor VIII preparations were seropositive, compared with none of 11 patients treated exclusively with cryoprecipitate obtained from volunteer blood donors. Of patients who were seropositive for HTLV-III antibody, 94% had abnormal T4/T8 ratios, and 33% of those whose serum was antibody negative had abnormal T4/T8 ratios; five patients, each antibody positive, have lymphadenopathy syndrome. Sequential studies in a subset of patients indicate that there is a changing pattern of antibody production to HTLV-III antigens after seroconversion

Using Extension Phosphorus Uptake Research to Improve Idaho\u27s Nutrient Management Planning Program

Irrigated silage corn is the main crop used for P removal in southern Idaho; however, little is known about the actual amounts of P removed under southern Idaho growing conditions. The study surveyed P removal by irrigated silage corn in primarily manured southern Idaho fields and wide-ranging soil test P. Whole plant corn tissue P concentrations ranged from 0.116 to 0.307% total P and averaged 0.208%—lower than Natural Resources Conservation Service (NRCS) estimates used prior to 2007 (0.26%P) but higher than estimates used since 2007 (0.185%). The study was used to update the OnePlan.org© Nutrient Management planning online program

Pulmonary rehabilitation referral and uptake from primary care for people living with COPD: a mixed-methods study.

Healthcare service and patient barriers contribute to low referral to and uptake of pulmonary rehabilitation (PR). Solutions should support skilled clinician-patient conversations and span primary care-PR boundaries to prevent disjointed working. http://bit.ly/2PVKHZf

Evolution by Any Other Name: Antibiotic Resistance and Avoidance of the E-Word

The word "evolution" is rarely used in papers from medical journals describing antimicrobial resistance, which may directly impact public perception of the importance of evolutionary biology in our everyday lives
