ABSTRACTBangun-bangun [Plectranthus amboinicus] is a functional vegetable that is used as lactagogue. This research was aimed to provide information of the effect of organic fertilizer on shoot, total phenolic, and anthocyanin production of bangun-bangun. This experiment was conducted at Bogor Agricultural University, Leuwikopo experimental station (Indonesia), from December 2012 to February 2013. The experiment was laid out in randomized block design with single factor with five combination of organic fertilizer treatments (combination of cow manure 12.3 t ha-1, rock phosphate 1.5 t ha-1, rice-hull ash 5.5 t ha-1) with three replications. The result showed that application of organic fertilizer increased of shoot production. Application of 12.3 t ha-1 cow manure + 1.5 t ha-1 rock phosphate + 5.5 t ha-1 rice-hull ash produced shoot dry weight ha-1 (57.33%) and metabolite production ha-1 (total phenolic 12.06%, anthocyanin 41.73%) higher than no fertilizing (P > 0.05). Application of cow manure + rock phosphate produced the lowest shoot dry weight ha-1 and metabolite production ha-1. The result of this research suggested that nitrogen, phosphorus, and potassium were needed on shoot production of bangun-bangun.Key words: Plectranthus amboinicus, phenylalanine ammonia lyase, secondary metabolite

This study was aim to examine the response of growth and biomass of oil palm seedlings in the pre-nursery to the application of NPK and mycorrhizal compound fertilizers. This research was conducted in April - June 2022 (4 months). A factorial randomized block design was implemented in this experiment. The first factor was the dose of NPK fertilizer which consisted of four (4) different treatment levels: Control/without NPK, 10 g/polybag, 15 g/polybag, and 20 g /polybag. The second factor was the dose of arbuscular mycorrhizal with four (4) different treatment levels, namely: Control/without mycorrhizal, 5 g/polybag, 10 g/polybag, and 15 g/polybag. These two factors resulted in 16 treatment combinations. Each treatment combination was repeated three (3) times so that there were 48 experimental units. Based on the results of the study it can be concluded that the application of NPK fertilizer combined with arbuscular mycorrhizal fungi on oil palm seedlings gave a significant interaction with the variables of the number of leaves (age 6, 7, and 11 WAP/Week After Planting) and stem diameter (age 6 WAP). but no significant interaction was shown on the variables: seedling height, root length, and plant biomass. The combination of 15 – 20 g of NPK/polybag with 10 – 15 g of mycorrhiza/polybag resulted in a higher number of oil palm seedling leaves than without NPK and mycorrhizal fertilizers at the age of 6 and 7 WAP. INTISARIPenelitian ini bertujuan untuk menguji respons pertumbuhan dan biomassa bibit kelapa sawit di pre-nursery terhadap pemberian pupuk majemuk NPK dan mikoriza. Penelitian ini dilaksanakan pada bulan April - Juni 2022 (4 bulan). Rancangan acak kelompok faktorial diimplementasikan dalam percobaan ini. Faktor pertama adalah dosis pupuk NPK yang terdiri dari empat (4) taraf perlakuan yang berbeda, yaitu: P0 (tanpa pemberian NPK/kontrol), P1 (10 g/polibag), P2 (15 g/polibag), dan P3 (20 g/polibag). Faktor kedua adalah pemberian dosis mikoriza arbuskula dengan empat (4) taraf perlakuan yang berbeda, yaitu: M0 (tanpa pemberian mikoriza/kontrol), M1 (5 g/polibag), M2 (10 g/polibag), dan M3 (15 g/polibag). Kedua faktor tersebut menghasilkan 16 kombinasi perlakuan. Setiap kombinasi perlakuan diulang tiga (3) kali sehingga terdapat 48 unit percobaan. Berdasarkan hasil penelitian dapat disimpulkan bahwa pemberian dosis pupuk NPK yang dikombinasikan dengan cendawan mikoriza arbuskula pada bibit kelapa sawit memberikan interaksi yang nyata terhadap peubah jumlah daun (umur 6, 7, dan 11 MST) dan diameter batang (umur 6 MST), namun interaksi yang tidak nyata ditunjukkan pada peubah: tinggi bibit, panjang akar, dan biomassa tanaman. Kombinasi pemberian 15 – 20 g NPK/polibag dengan 10 – 15 g mikoriza/polibag menghasilkan jumlah daun bibit kelapa sawit yang lebih banyak dibandingkan tanpa pemberian pupuk NPK dan mikoriza pada umur 6 dan 7 MST.

The article discusses the Measurement of Impact Assessment on the Coffee Farmer Empowerment Program in South Tapanuli. Data collection techniques were obtained from in-depth interviews, FGDs and direct observation of all relevant stakeholders. The data results are used as a unitary material together with the SROI calculation. SROI is currently the most generally accepted way of explaining the monetary value of the social, economic and health outcomes of an initiative. Social return on investment (SROI) is a framework used to measure and account for the value created by a program or series of initiatives, beyond financial value. In order to calculate the benefit to cost ratio, SROI uses monetary values to represent social, economic and health outcomes. For example, the 4:1 ratio in the SROI analysis shows that an investment of IDR 1 generates IDR 4 of social value. Based on the results of the SROI calculation, the SROI ratio reached 1: 2.29. This ratio means that every IDR 1 invested in the Iron Green House program is capable of producing a social impact of IDR 2.29. As a new initiative in the implementation of the TJSL program that departs from environmental issues, the number of these ratios is large enough to produce social impacts. Keywords: Coffee Farmer Empowerment Program, Environmental Issues, Economic Outcomes, Social Impacts
