Abstract

Research has been conducted on VCO emulsion drinks with the addition of purple sweet potato extract. The research was conducted using the complete randomized design (CRD) method with 5 treatments (A, B, C, D, and E) and 3 replications so that 15 experimental units were obtained. The treatment variations were A = VCO + 0 g Purple Sweet Potato Extract (control); B = VCO + 2 g Purple Sweet Potato Extract; C = VCO + 4 g Purple Sweet Potato Extract; D = VCO + 6 g Purple Sweet Potato Extract; E = VCO + 8 g Purple Sweet Potato Extract. Parameters that were then observed were the stability of the emulsion, viscosity, pH, total phenolic, antioxidant activity, total anthocyanin, and level of liking (hedonic test). The data obtained were then analyzed using one-way analysis of variance (ANOVA) using the SPSS 22 program at the 5% confidence level. The results of the emulsion stability test showed the highest antioxidant activity of VCO emulsion drink was 41.627% in sample E or with the addition of 8 g of purple sweet potato extract. The more purple sweet potato extract is added, the more antioxidant activity will also increase. The same applies to the total phenolic content and total anthocyanin content. The more acidic extracts that are added, the lower the emulsion stability. The viscosity of the VCO emulsion drinks made had values of 85.66 - 127.19 cP. Citric acid contained in purple sweet potato extract affected the pH of the emulsion which ranged from 5.44 - 4.81. Organoleptic test results showed panelists liked the VCO emulsion drink with the addition of purple sweet potato extract and honey in terms of aroma, texture, taste, and color. Keywords: Antioxidant, VCO, Purple Sweet Potato Abstrak Telah dilakukan penelitian tentang minuman emulsi VCO dengan penambahan ekstrak ubi jalar ungu. Penelitian dilakukan menggunakan metode rancangan acak lengkap (RAL) dengan 5 perlakuan (A, B, C, D, dan E) dan 3 kali ulangan sehingga diperoleh 15 satuan percobaan. Variasi perlakuan yang dilakukan yakni, A = VCO + 0 g Ekstrak Ubi Jalar Ungu (kontrol); B = VCO + 2 g Ekstrak Ubi Jalar Ungu; C = VCO + 4 g Ekstrak Ubi Jalar Ungu; D = VCO + 6 g Ekstrak Ubi Jalar Ungu; E = VCO + 8 g Ekstrak Ubi Jalar Ungu. Parameter yang kemudian diamati  yakni stabilitas emulsi, viskositas, pH, total fenolik, aktivitas antioksidan, total antosianin, dan tingkat kesukaan (uji hedonik). Data yang diperoleh kemudian dianalisis menggunakan sidik ragam atau analisis variansi (ANOVA) satu arah menggunakan program SPSS 22 pada taraf kepercayaan 5%.                Dari hasil uji stabilitas emulsi menunjukkan aktivitas antioksidan tertinggi minuman emulsi VCO yaitu sebesar 41,627%  pada sampel E atau dengan penambahan 8 g ekstrak ubi jalar ungu. Semakin banyak ekstrak ubi jalar ungu yang ditambahkan, maka aktivitas antioksidan juga akan semakin meningkat. Begitu pula dengan kandungan total fenolik dan kandungan total antosianin. Semakin banyak ekstrak yang bersifat asam yang ditambahkan maka dapat menurunkan stabilitas emulsi. Viskositas pada minuman emulsi VCO yang dibuat memiliki nilai 85,66 – 127,19 cP. Asam sitrat yang terkandung pada ekstrak ubi jalar ungu memengaruhi pH emulsi yang berkisar pada 5,44 - 4,81.

Abstract

Spodoptera frugiperda is a dangerous invasive pest because its life cycle is short and is often known by farmers as the brown armyworm pest on corn plants. Armyworms are included in the category of pests that are most difficult to control because the adults spread quickly and can fly long distances quickly. Armyworm control by farmers in Tomohon City generally uses synthetic pesticides. This activity aims to determine the use of the botanical insecticide soursop leaves, Pangi leaves, and citronella leaves against S. frugiperda pest attacks on corn plants. The research experiment was arranged in a randomized block design consisting of vegetable insecticide treatment from extracts of soursop leaves, Pangi leaves and citronella leaves treated with surfactant and a control. Each treatment was repeated 4 times. For one treatment, 20 corn plants are required. The application of vegetable insecticides is carried out 5 times with an application interval of once a week in the vegetative phase. The results of research on plant-based insecticides consisting of soursop leaf extract, Pangi leaf extract, and citronella extract are very effective in suppressing damage caused by Spodoptera frugiperda pests.  Fruit weight in soursop leaf extract weighed 314.59 grams per fruit, Pangi leaf extract weighed 338.75 grams per fruit, citronella extract weighed 345.00 grams per fruit and control weighed 230.14 grams per fruit Keywords: Botanical Insecticide, Spodoptera frugiperda   Abstrak Spodoptera frugiperda  merupakan salah satu hama invasif berbahaya karena siklus hidupnya pendek oleh petani sering dikenal sebagai hama ulat grayak coklat pada tanaman jagung.

Abstract

The illicit wildlife trade is a significant global issue, compounded by the increasing use of social media platforms. This study explores the dynamics of protected wildlife trade through social media and evaluates law enforcement responses in North Sulawesi, Indonesia.  This case study was conducted at the Regional Environmental and Forestry Law Enforcement Office in Manado, integrating interviews, surveys, and thematic analysis over a span from 2016 to 2023.  Results showed that social media, particularly Facebook, was utilized in 71% of the wildlife trade cases, predominantly involving avian species. Traders employed sophisticated methods including the use of anonymous accounts and disguised packages to evade detection. Law enforcement operations have included forest security traps and wildlife circulation interventions, but challenges remain in prosecuting major financiers and dismantling international networks.  It can be concluded that effective enforcement is hindered by technologically sophisticated traders and the need for more robust international cooperation and legal frameworks. Keywords: wildlife trade, social media, law enforcement, North Sulawesi. Abstrak Perdagangan satwa liar ilegal merupakan masalah global yang signifikan, yang diperparah dengan penggunaan platform media sosial yang meningkat. Studi ini mengeksplorasi dinamika perdagangan satwa liar yang dilindungi melalui media sosial dan mengevaluasi respons penegakan hukum di Sulawesi Utara, Indonesia.  Studi kasus ini dilakukan di Kantor Penegakan Hukum Lingkungan dan Kehutanan Daerah di Manado, mengintegrasikan wawancara, survei, dan analisis tematik selama rentang waktu dari tahun 2016 hingga 2023.  Hasil menunjukkan bahwa media sosial, khususnya Facebook, digunakan dalam 71% kasus perdagangan satwa liar, terutama melibatkan spesies burung. Para pedagang menggunakan metode yang canggih termasuk penggunaan akun anonim dan paket yang menyamar untuk menghindari deteksi. Operasi penegakan hukum telah mencakup perangkap keamanan hutan dan intervensi sirkulasi satwa liar, namun masih ada tantangan dalam menuntut para pemodal besar dan membongkar jaringan internasional.  Dapat disimpulkan bahwa penegakan hukum yang efektif terhambat oleh pedagang yang cakap teknologi dan kebutuhan akan kerja sama internasional serta kerangka hukum yang lebih kuat.

Abstract

Watershed is a plain area bounded by hills or mountains that serves to store, accommodate, and drain water from upstream to downstream of the river. Watersheds (DAS) are part of the unity of resources where humans actively use them. In this study, the aspect studied was the condition of the soil texture which aims to determine the erodibility (K) of the soil around the Kombot watershed. This study used survey methods and laboratory analysis to obtain data on soil texture and erodibility (K).The results showed that: 1) The soil erodibility value was very high in the soil sample (1) with a K value of 0.60 at a slope of 0-400 with land use namely moor while soil texture class was dusty clay, 2) The soil erodibility value of low value is found in the soil sample (13) with a K value of 0.17 on slopes 9-140 with plantation land use while the soil texture class is sandy loam, 3) soil texture is a factor that affects the value of soil erodibility (K), because soil texture has sensitivity to erosion. Key words: Kombot watershed, soil erodibility, soil texture Abstrak Daerah Aliran Sungai (DAS) merupakan suatu wilayah dataran yang dibatasi oleh perbukitan atau pegunungan yang berfungsi sebagai tempat menampung, menampung, dan mengalirkan air dari hulu ke hilir sungai. Daerah Aliran Sungai (DAS) merupakan bagian dari kesatuan sumber daya yang dimanfaatkan secara aktif oleh manusia. Dalam penelitian ini aspek yang diteliti adalah kondisi tekstur tanah yang bertujuan untuk mengetahui erodibilitas (K) tanah di sekitar DAS Kombot. Penelitian ini menggunakan metode survei dan analisis laboratorium untuk memperoleh data tekstur dan erodibilitas tanah (K). Hasil penelitian menunjukkan bahwa: 1) Nilai erodibilitas tanah pada sampel tanah sangat tinggi (1) dengan nilai K 0,60 pada kemiringan 0-400 dengan penggunaan lahan yaitu tegalan sedangkan kelas tekstur tanah lempung berdebu, 2) Nilai erodibilitas tanah yang bernilai rendah terdapat pada contoh tanah (13) dengan nilai K sebesar 0,17 pada lereng 9-140 dengan penggunaan lahan perkebunan sedangkan kelas tekstur tanahnya adalah lempung berpasir, 3) tekstur tanah merupakan faktor yang mempengaruhi nilai erodibilitas tanah (K), karena tekstur tanah mempunyai kepekaan terhadap erosi.
